The device has a system computer 100, a central programmable

basic clocking circuitry. South central controller 108 and a plurality of independent zone drive means. In the system part shown, the independent zonal drive means for feeding the primary coil windings represented by coils 138, 142, 146 and 150 are zonal drive devices such as 136 drives.

140, 144 and 148, and zone controllers, such as zone controllers 128, 130,132 and 134, each of which is connected to a respective zone drive associated with it. In the system central

5, a controller 108 is connected to each zone controller, a central programmable basic clock circuit 106 is connected to the central controller 108 and provides clock signals to the zone controllers through the central controller 108; system computer 100 is connected to a central programmable base clock circuit 106, a central controller

5 to 10 and zone controllers 128, 130, 132 and 134 via a data communication bus 102. A system with this configuration is designed to operate in a variety of stable states and in transition state for

0 making the transition between stable states.

It is also contemplated that the system of the invention may operate in one steady state. When the system has such

5, it includes all elements of the described system except for the system computer 100 and central controller 108. A central programmable basic clock circuit 106 is connected to each zone controller and provides clock signals to the zone controllers to control their respective outputs. Zone controllers with this

5 embodiments have only one memory that contains instructions for one steady state.

System computer 100 provides overall supervisory control of the system of My invention. The computer 100 is connected to the data communication bus 102 and generates, among other things, control information for initiating changes in the operation of the system steady state.

5 Computer 100 also downloads information to the three storage devices of all zone controllers for storage. This information is intended to create three different signal supply structures.

Central controller 108 is a logic circuit used to control the state in which the system is operating. The operating states of the system are the first steady state, the atomic steady state, and the transition state for transitioning from the first steady state to the second. The outputs of the central controller 108 determine which memory of the zone controller is selected to create a power signal to power the primary coil of a specific zone. It also provides clock signals from a central programmable base clock circuit 106 for accessing the selected memory in order to send the binary instructions contained therein from the zone controller to the zone drive device. The central controller 108 performs two-way communication with the data communication bus 102 both to send information and to receive it from the computer 100.

The central programmable base clock circuitry 106 generates a constant frequency pulse signal for the central controller 108, which in turn provides a base clock or subset signal to each zone controller. The signal generated by the base clock circuit 106 is a conventional base clock signal used to synchronize the output of the zone controllers. The output pulse rate of the central programmable base clock circuit 106 can be tuned up to various desired values by commands received from the system computer, which are set by the operator. This makes it possible to increase or decrease the speed scale of the secondary windings without changing the ratio of speeds and the relative pitch between the secondary windings.

Zone controllers 128, 130, 132 and 134 characterize all zone controllers of the system of the invention. These controllers are used to store binary commands of the characteristics of the supply signals in order to create an EM wave for a specific zone of the primary winding, which is connected through a separate zone drive device.

Zone actuators 136, I40, 144 and 148 are connected together with the described zone controllers to which they are connected ;;

device. Each zonal underfloor is half a three-phase AC input from an external source, which is then rectified and filtered to create a DC power supply. The stop current power is supplied through pairs of power transistor switches, which are switched to provide a frequency-controlled AC output signal in the primary winding. Take the zonal drive device-136 as an example: it receives digital input signals from the connected zonal controller 128. The digital input signals are fed to the input of the gate logic circuit of the zonal drive device 136, the output of which causes the switching of the SIP transistor switch to produce, for example, a six-step output signal type with an energized primary coil coil for generating a traveling EM wave. The zonal drive device (drive 136) has a well-known construction: the drive devices are modified by the aforementioned gate logic circuitry for switching the switches on the power transistors and the voltage control circuit.

The primary winding coils 138, 142, 146 and 150 represent specific winding coils of the zones which are powered by a separate zone drive means consisting of a zone controller and a zone drive device. Egi coils are malicious, that in this zone you can see that i-ash is moving with a magnet

In FIG. 2, the primary winding 152 and the secondary windings 160 and 1 70 are typical for PSD with a short secondary winding. Primary winding 152 is a cross-sectional view of a portion of an elongated primary winding. From FIG. Fig. 2 shows independently energized discrete adjacent zones (pos. 184. Zone 1 is a constant-velocity zone, i.e., as zones 2–4 pre, GGT: are acceleration zones in the acceleration coil is primary; windings 152. The primary winding 152 has a base 154 for accommodating coil turns & 06 and 0 C. There are adjacent i-teeth 156 d of needles adjacent to the grooves 154, which are intended to complete the TPG. group of the NM-current of d / 1 creating a moving EM wave The path is current ccj, voic in the usual way, typical for (1 LSD and rm-readable for the player about and dango. -techniques, V; gn.egaymu not treGg / .t d: p.h-j obznzni In a typical example, the turns of the primary coil are related to the chord 2/3.

In the example shown in FIG. 1, the frequency of the three-phase feed sigma generated from the primary winding is constant in constant speed zone 1, and also in acceleration zones 2-4. However, it is believed that the three-phase supply signal used by the primary power supply of the primary winding coil of the acceleration zone has a frequency that changes over the course of the EULMR, providing a frequency slope of the signal to increase or decrease the secondary winding speed, which is accelerated by this, the xioe is filled with ronigo It is connected with a varnishing medium ZM halfway, PNRBAT-PASMOP in the primary winding by a feeding gig dad.

The coils which are located j1 n Zr) -1L4 are shown, for example, as A and A (bar over a certain booklet means pa - the ancestor of the positive current R katuix is opposite to the direction of a to k in katutsk, which does not have a primary designation).

Secondary windings, while KIR. To 160 and 170 are advanced along the perpendicular winding 1/2 with a perennial EG /, are full, created by the pin. It is preferable to install the secondary windings on the monorail for movement along the primary winding. Between the primary and secondary windings, there is usually an air gap when on the monorail. Secondary winding 160 has conventional permanent magnets 162 and 164 located at the bottom surface. These magnets provide reverse polarity at the lower surface of the secondary winding adjacent to the primary winding 152, but somewhat distant from it. The magnetic poles 162 and 164 are separated by a distance of one pole pitch or I, which matches the fixed pole pitch of the primary winding. The adjacent secondary windings, such as 160 and 170, have the opposite arrangement of their magnets. For example, the secondary winding 160 has a magnet 162, which is the north pole, followed by a magnet 164 representing the south pole, while the adjacent second winding 170 has a magnet 172, which is the south pole, followed by the magnet 174, representing north pole Neighboring secondary windings have reverse poles, which makes it possible to arrange adjacent secondary windings in the same zone, which divide 1 I between the magnetic boundaries of adjacent secondary windings. However, magnets can be arranged in a repeating combination. in neighboring secondary windings, for example, north / south - north / south. If the magnets are arranged in this way, the minimum distance separating the magnetic boundaries of the adjacent secondary windings should be 2 I.

With motivation, the moving EMs are full, if we take the example of momentum in Fig. 3, the current in the C-phase coils has a maximum positive value. Therefore, in zone 1, the current in the C-phase coils 190 and 198 flows in a counterclockwise and clockwise direction To the merchant's home 192 This will mean that on the digital designation 182, according to the well-known right-hand rule, the north pole is created by coils 190 and 198, and the south pole by coil 192 of zone 1. As shown in pos. 180, along the T1 line, the south pole The C-phase coil 192 of zone 1 is coupled to Sevep np “the pole of the magnet 162 of the secondary winding 160 and the north pole above the C-veil coil 198 of zone 1 is engaged with the south pole of the magnet 164

All zonal accessory devices 136, 140, 144, and 148 for zones of 1 liter do not generate power signals n to not instantly

are coordinated at the junctions between the zones along the length of the primary winding 152, For example, about the last C-phase coil of zone 1, a positive current flow in the counterclockwise direction generates a north pole; in the C-phase coil of zone 2, a positive current flow in a clockwise direction generates the south pole; in the C-phase coil of zone 3, the positive current flow in the non-directional direction counterclockwise generates the north pole, and in the C-phase coil of zone 4 the positive current flow in the clockwise direction generates the south pole. This arrangement C, C is repeated along the entire length of the primary winding for the C phase coils. This is also true for A-phase and B-phase coils. Thus, north and south poles are generated along the primary winding 152 to interlock with the magnets and advance the secondary windings 160 and 170. In addition, since there is a distance of 2 A between the center lines of the nearest poles of the adjacent secondary windings, the secondary winding 170 can be accelerated regardless of the secondary winding 160. because each accelerated secondary winding will always be in a separate zone at any given point in time, therefore, subject to the individual frequency slope of the supply signal us or the zones through which they promote it.

Take now T2: the next peak current coil to generate a moving EM wave to propel the secondary coils is a B-phase coil. As can be seen from FIG. 3, at time T2, the current in the B-phase coil has a maximum negative value. Essentially, current will flow in the opposite direction to the arrow direction of coil 196. Note the alternation of polarities for the B phase coils along line T2 for zones 1-4 in the same shape as described above for C phase coils. When shifted from T1 to T2, the B phase coil 196 changes pole from north to south. This will advance the north pole of the magnet 162 of the secondary winding 160 to the right, thereby moving the secondary winding along the primary winding 152 by shorting the magnetic poles of the secondary winding 160 to a traveling EM wave. By clock action, the secondary windings 160 and 170 advance along the primary winding along with the moving EM wave. Moreover, although one secondary winding can be advanced through two zones in one, because

the smallest zone may be 1) long. while the secondary winding is 2 A, there is never a situation in which more than one secondary winding is simultaneously in the same acceleration zone.

Fig. 4 is a block diagram of a portion of the system of the invention showing the relationship between the primary and secondary windings as they move along the primary winding from the acceleration section and further to the second constant speed section. Secondary windings are initially included in the system at fixed time intervals at or near the first constant speed and in synchronism with the full GP. In Fig. 4, secondary windings 200 are more characteristic. 202, 204, 206, 208,210, 212, 214, 216, 220, 222 and 224, sold along an elongated primary winding 152, The primary winding 152 is divided into three sections, namely the first constant speed 300, acceleration (positive) portion 302 and fifth constant speed portion 304. FIG. 4 is a point in time showing the relative position of each secondary winding relative to the others currently in the system. The offshore constant speed section 300 is designed to advance the secondary windings at a speed lower than the speed on the second constant speed section 304. However, it should be understood that “in the first constant speed section 300, secondary windings can be advanced at a speed greater than the speed on the section the second constant SPEED 304, in this case, the acceleration portion 302 will be the negative acceleration portion, and the size of the zones will decrease along the length from the left to the right, and not increase.

Each section is further divided into one or more zones that are connected to individual zonal drive means (Fig. 1), of which only zonal drive devices are shown. The section of the first constant speed is 300 rp: it contains only one zone, zone 1 (308), with which the drive device 136 is connected; the acceleration section includes six zones, here the input device 140 is connected to zone 2 (310), the drive device 144 is connected to zone 3 (3 2), the drive device 148 is connected to zone 4 (314). the drive device 226 - with zone 5 (about 16), the drive device 228 - with zone 6 (313) and the input device 230 - from zones: hey 7 (320), about the site of this constant speed 304 includes three zones, where the drive device 232 is connected to Ground 8 (332), the drive device 234 is connected to zone 9 (324) and the drive device 236 is connected to zone 10 (326).

The portion of the first constant speed 300, in which the secondary windings 200, 02, 204, 206 and 20B are closely spaced, represents SOYOE one zone 1 (308). The hill windings advance from the section of the first constant SPEED 300 to the section of positive acceleration 302. In this section, the speeds of the secondary windings, currents like 2 SO, 212, 2.14 and 216 increase independently as they move to the right. Secondary windings then pass south from the acceleration section 302 to the second constant speed section 301, at which the speed of the secondary windings, such as 220, 222 and 224, is constant.

Schedule 350 is a graph of the speed of the secondary windings depending on the size of the primary primary circuit: Graph 1 350 and 306 at the beginning of the frequency rise shows a 2 A segment. It is necessary to ensure that the secondary winding, the xyural has a length of Ј I, halfway through the first acceleration zone, until the speed increases. In phi), the li-system is in operation and in a steady state. Secondary windings go to the system in sections of persons of constant speed 300 at short intervals. As shown via (Jn.r. 4, this is an internal circuit with a length of 3 A and includes the length of the secondary windings 2 A and the gap 1 X between the magnetic boundaries of the adjacent secondary windings. However, the secondary windings can enter the system through unequal spacing W when removing the ONMU in unforgettable windings and leaving others in the same position vigorously with OM holia, i.e., secondarily windings 202 and 204 are very removed, the unequal gap has been fixed, but atorichesky OPMST-200 to / sna carry the same positional interconnection s with created EM ROLNA.

The acceleration section 302 has zones of increased length, which is especially noticeable when comparing the length of zone 2 (310) with the length of zone 7 (320). The increased length of the zones in the acceleration section 302 facilitates the use of an economical method for separating the secondary windings by increasing their speed in separate zones, based on finding only one secondary winding in a certain zone at any given time, as well as crossing and leaving each secondary ob at least odmti SOHJ, except for zone 1. in

over a fixed period of time However, there is no need for tones to have extended lengths. Each zone along the entire length of the primary winding may

have the same length, for example 1. If this is the case, you just need to add additional zone drive units and corresponding zone controllers to accommodate the increased number

0 zones.

FIG. 5 is a detailed block diagram of a representative zone controller of the drive means. The zone controller shown in FIG. 5. has

5, the numeral 128 that indicates the zone controller for zone 1 in FIG. 1. Zone controller 128 has 400 random access memory access logic and three pairs of rewritable address

0

random access memory counter

(RAM), namely a RAM X steady state pair including an address counter 402 and a random access memory 404; a RAMZ transition state pair, into a key a address counter 406 and a random access memory 408; and a steady state RAMZ pair including an address counter 410 and random access memory 412. Also included in the local controller 128 are a linear drive 416 and a local programmable base clock 414. A RAM Y pair is analogous to a stable pair RAM X status and

5 7 except that it has an additional memory connected thereto.

As mentioned above, the zone controller needs to have only one memory if the system should work only in one stable state. In such an embodiment, the zone controller will contain only one pair of rewritable random access address counter / memory. Since this is the embodiment

5 should only operate in one stable state, random access memory access logic 400 is also excluded, while the rest of the area controller remains the same as shown in FIG. 5. The memory of each zone controller contains binary instructions for the frequency and phase characteristics of an individual signal.

In a preferred embodiment, each of the three random access memory devices stores binary instructions for the frequency and phase characteristics of an individual signal. For example, memory with 404 access will be TM-V / VJ d | h; -, YUROY

and frequency characteristics of the steady state signal, random access memory 408 are binary instructions for the phase and frequency characteristics of the transition state signal, and random access memory 412 are binary commands of phase and frequency characteristics of the second steady state signal other than those that is stored in memory 404. The binary instructions stored in each type of RAM X, RAM Y and RAM Z in all zone controllers have the same fixed number of addresses. The binary instructions for these signals and their application will be described in more detail below, but at this stage it must be understood that the binary instructions for the transition signal stored in random access memory 408 are used to transition from the binary instructions for the signal a stable state stored in random access memory 404 to binary instructions for a stable state stored in random access memory 412.

The contents of the selected random access memory are output from the random access memory sample logic 400 and supplied to the linear random access device 416. The random access memory selected by the RAM 400 sample logic will correspond to the signals received from the central controller 108 along lines 116 , 118 and 120. Typically, a random access memory type is sampled in all zone controllers of the system. For example, for the first steady state operating condition, the central controller 108 supplies input signals to all the random access memory logic circuits of the zone controllers to select PAM X, 404. This is necessary because the supply signals for neighboring zones are matched at the junction when a random access memory device of a certain type is selected.

During operation, the basic clock pulses, namely the signal 144 of the basic clock circuit X, the signal 112 of the basic clock circuit Y and the signal 110 of the basic clock circuit Z are supplied from the central controller 108 to the respective address counters of the random access address rewritable counter / memory pairs when This memory is selected. Consider, for example, a pair of rewritable random access memory counter / memory, consisting of 402 and PAM 404: here, the signal of the gross circuit of the Poami X detrobes the address counter 402. The signal 114 of the basic circuit is clocked-5 mil X, then RAM 404 based on it, it generates an output signal, Address counter 402 sequentially passes through all random access memory addresses RAM 404 v,

0 sequence when RAM 404 reaches the last preprogrammed address.

The central controller 108 controls which signals from all the logics5 of the E random access memory access circuit packs by choosing the same random access memory types, be it RAM X. RAM Y or RAM Z. for all zone controllers and start 0 from them all in unison. Since pse memory devices with random access RAM X C -: e; from the same number of cor. ND and VSO are gated by a common clock signal - base signal 114

5 of the X scheme. Then they all go through their addresses sequentially, reach their final address and start again at the same time. Because ego tzk, the central controller 108

0 it is only necessary to control the overflow lines 122,124 and 120 of one zone controller for overflow of address counters Z, Y and X, respectively, in order to determine the moment of reaching the end of memory of each type of RAM if it is necessary to select a new type of RAM. The choice of a new random access memory can only happen after reaching the final address of the random access memory, to

0 which occurs in the summer time. When switching from one memory with random access to another, there should be no interruption in the issuance of commands by the zonal drive device. Thus, following the last output data from the currently used random access memory, the following data will be output, which is the first output data from the newly “

0 of the selected random access memory d based on the next clock.

In FIG. 6 is a logical truth table for the RAM 400 sampling logic. Latch enable signal 116, select-1 110 signal, and pick-up, select 0 120 coming from central controller 108, determine which random access memory is selected for output by RAM sample logic 400. When the enable enable signal 116 has a false value of 1, and both the select-11 signals 118 and the selection - p 120 have a logical O value, the random access memory devices are disabled and the output value of the PAM 100 sampling logic is logical O.

If the enable enable signal 110 again had a checkmark value, the select signal - 113 - the logical value of G, and the select signal - Ј120 - the value of the logical O, for the output to the linear non-linear drive device 416, RAM 400 sample logic selects the transition state RAM V (RAM 403). When the enable enable signal 116 riMcer has a logical value of 1, while both CHIs select-1 18 and select 0120 have T. Log value is-1 for output from RAM 400 sample tray to linear drive 416 RAM sample logic 416 selects RAM Z steady state (RAM 412). When the enable enable signal 116 has a logical O value, the RAM 400 sample logic latches its output value that was prior to the logical O value. This output value will be a 3-digit value from one of the random access memory devices.

In FIG. 7 shows the logical truth table of the outputs from the central controller 108 with respect to the logical states of the RAM 400 sampling logic. When the random access memory devices are locked, the select signal is 1 118, the signal is select 0 120, signal 114 is the basic clock circuit X, signal 112 is the basic circuit clock Y and the signal 110 of the base clock circuit Z have logical O values from the central controller 108, when you want to select

PAM X, the select-1 118 signal has a logical value of O, the signal 114 of the basic clock circuit X is supplied from the central controller 108 to gate the address counter 402, and the signal 112 of the basic clock circuit Y and the signal 110 of the base clock circuit Z have a logic value of 0. When it is required to select PAM Y. signal 118 select-1 has a logical value of 1, and signal select-0 120 has a value

logic O, a signal 112 of the basic clock circuit Y is supplied from the central controller 108 to gate the address counter 406, while the signal 114 of the basic clock circuit X and the signal 110

of the basic clock circuit Z have a value of logical O. When it is necessary to select RAM X, the signal 118 select-1 and the signal 0 120 select-have a value of logical 1, a signal 110 of the basic clock circuit X is supplied from the central controller 108 to gate the address counter 410, and the signal 114 of the basic clock circuit X and the signal 112 of the basic clock circuit Y have a value of logical O.

In FIG. 8 is a diagram of a zonal drive device 136. It will be appreciated that FIG. 8 merely characterizes all zonal drive devices of the system of the invention. As noted, zone drive devices, such as drive devices 136, are modified by incorporating the logic gate 520 circuitry and parts of the frequency-voltage converter

5 to the second busbar 531 of the drive unit and switches the inverter 527 to match the voltage of the second busbar of the drive unit with the voltage setting point provided by the voltage control system. Part of the output electronic circuit 508 is designed to disconnect the zone drive unit 136 in the event of a potential state of the art. A part of the output protection of the circuit 508 detects any fault on the goku via the shunt 524 and sends the corresponding signal to the logic gate circuit via the output trip line 510 to open all the hoist transistors, which is necessary to protect the drive unit 136.

The gate logic circuitry 520 of the zonal drive unit provides a digital input to the SILOVIR transistor switches to control the output of the zonal drive unit 136 to power the primary windings 0 A, 0 V, and 0 C of the coil 138 of the primary 152. 4-bit passive an input signal 500 is supplied from the linear drive device 416 of the zone controller 128 (shown in FIG. 5) to the input of the zone drive device 136. Of the 4-bit parallel input signal, 1 bit feeds the frequency for part of the reference zovatel voltage control circuit voltage and the output protection 508 to determine the average levels of n voltage for the drive unit, and the other 3 bits contain the binary yes command for switching the power transistor switches and a frequency control circuit of the supply signal for powering namogki phase 0n. 0V and 0C coil 138.

Input A connected to turns 0L of the primary winding coil is fed to opto-isolator 514, input B connected to turns 0 V of primary coil is fed to opto-isolator 516, and RHOD C connected to turns 0 From the coil, to the opto-isolator 518.

In FIG. 9 is a logical truth table for the inputs and outputs of the gate logic of the zonal drive device 520 shown in FIG. 8. Three bits from line 500 causes the power transistor switches to switch, resulting in a six-step supply output CHI cash / bank of each phase coil, which is consistent with the frequency structural shown in FIG. 3.

FIG. 10.

As noted, an alternating current cycle causes the EM wave to move one pole step or 1 A. Therefore, the position of the secondary winding promoted by such an EM wave relative to the primary winding zone can be tracked by binary command signals, as indicated by the notation I under the 0 A graphs. The length of the primary winding zones is equal to or a multiple of 1 A. This will mean that any secondary winding will always be transferred from one zone to the next in a multiple of A position. However, the zones need not have equal A lengths.

When the secondary winding begins to enter the zone (and the GOO position), the phase angle is 0 °. At position 680, a frequency slope is also initialized based on a binary command at a memory address above address 200. Transmission and installation from the initial state occurs simultaneously at the same memory address. From the point of simultaneous transmission and initialization, the phase angle and frequencies increase over time, as shown by the positive slope of the instantaneous frequency curve. The ego is also seen from the smaller width of the corresponding pulses 0A, 0V and 0 C, when they move to the right, the frequency rise occurs continuously until the secondary winding but begins to move to the next zone of the primary winding at position 682 with a fozoy angle of 1080 ° and at the memory address directly preceding address 1100, where the next transmission takes place. The frequency for the zone that the secondary is leaving continues to rise until transmission is complete. Only after this is the frequency structure restored to its original state. During the initial state setup, the frequency structure also performs a 180 degree phase shift to receive the next secondary winding with oppositely spaced magnets.

FIG. 12 provides a mainly graphical representation of the complex frequency slopes of the acceleration portion of the system of the present invention. The frequency profiles that make up the complex frequency slopes are the repeating profiles of the saw tooth for each zone, which correspond to and overlap the profiles of the adjacent zone. This correspondence and overlapping allows smooth transfer of the secondary windings from one zone i. another one.

In order to properly promote the second; - Now the windings are preferable to have such

system design, in which any one secondary winding would pass through one specific acceleration zone or second constant speed of any length in a time less than fixed

0 cyclic time, which in figure 2 is designated as cyclic time T. Cyclic time T is a function of the initial minimum interval of the secondary winding and the actual speed

5 secondary windings when they enter the system. However, during the cyclic time T, only one secondary winding will enter a certain zone. When the system is running and the first is secondary

0 has reached the end of the primary, the system will contain the maximum number of secondary windings, so from this point, in order for some secondary winding to enter the system, the friend must leave it,

5 most support a constant number of secondary windings in the system.

In FIG. 12 shows the acceleration of the secondary windings from the first constant speed, which is indicated on F1 by the number 700,

0 of the second constant speed, having a higher value, which is indicated on F2 by the number 726. The frequency profile of zone 1 is a constant frequency profile operating at a frequency of F1, and the frequency

5, the zone 8 profile is a constant frequency profile operating at a frequency of F2. Intermediate zones (zones 2-7) with frequency rise profiles are the acceleration zones through which

0 acceleration of the secondary windings from the frequency F1. to frequency F2.

As shown in FIG. 12, cyclic time T is the time interval at which adjacent, closely spaced secondary windings enter the LSD system of the system of the invention.

Secondary windings A, B, C and D are individual secondary windings that are included in the first of a plurality of zones

0 acceleration from the first constant-speed zone at time intervals T. During to, the secondary winding, winding A moves along the primary winding s of zone 1 with a constant speed determined by the frequency

5 F1. When the secondary winding A moves further to the right in zone 1, at the time indicated by the number 714, it is transferred to zone 2, whose frequency and phase setting in the initial state were consistent with these parameters of zone 1 at point 714. Until

upon completion of the transmission, the frequency in zone 2 continues to operate with the frequency and phase parameters of zone 1. After completion of the transmission at position 702, the frequency in zone 2 begins to rise in accordance with a pre-programmed binary command stored in the zone controller of zone 2, in the usual case, in RAM X, 404. As the frequency rises, the secondary winding A positively accelerates c along the primary winding. Secondary winding A will continue acceleration in accordance with the frequency slope of the frequency profile of zone 2 until it reaches point 716 where it is transferred to zone 3. At transmission point 716, the signal of zone 3 and the signal of zone 2 are instantly matched by a change in frequency and phase when the secondary winding completely crosses the joint between the zones, and the secondary winding is smoothly transmitted. During transmission between acceleration zones, the system according to the invention matches a continuously changing frequency and phase, but does not interrupt the acceleration of the secondary winding with a flat constant-speed section, as is the case in prior art systems. After completion of the transmission, the frequency profile of zone 2 is set to its initial state.

After completing the transmission at point 716, subsequent transfers at points 718, 720, 722, 723 and 724 between the remaining part of the adjacent acceleration zones, between the last acceleration zone and the first zone of the second constant higher speed section and between consecutive zones of the second more high speeds occur in the same manner as described above.

As shown in FIG. 12, the secondary windings B, C, and D, one after the other, enter the system at multiple T times, namely, t0 + T, t0i2T and to + ЗТ, respectively, and are accelerated in the same way as the secondary winding A. Further, as seen from the drawing, not one of the secondary windings is simultaneously with the others in the same acceleration zone or second constant higher speed; consequently, independent acceleration and arrangement of individual secondary windings occurs.

In FIG. 13 is a graphical representation of the position with respect to time for twenty secondary windings traveling through the system of the invention. With reference to FIG. 13, steady state and transition state operations will be described.

Next to the abscissa of the graph shown in FIG. 13, characteristic zones 1-13 are located. the lengths of which are indicated in A in parentheses. The individual zones are indicated by abbreviations - 5, for example Z 3. which represents zone 3. The abscissa of the graph is marked by degrees of the phase angle together with their corresponding equivalents, expressed in A. The position along the primary winding of any fluorine that enters the system can determine its phase angle. This is because the pole pitch of the EM is faithfully fixed as A, which corresponds to the pole pitch of the primary coil, for example, phase 5 A - phase A, the warrior’s PM and any secondary bite synchronized with it will move from 2 I along the primary v-ahdom 360-degree phase change resulting

0 alternating current supplying the turns of the primary coil, which generates an EM wave. The cost. on which the secondary winding has moved along the primary, can be determined as follows

5 by the expression: The position of the secondary winding is 2 A (phases where the phase is measured in or degrees of alternating current divided by 360 °. Therefore, the position of the second phase of the secondary treatment can be primary

0 be there., As shown by the abscissa either in the phase angle or in (N) A - where N is a positive number.

The value of the binary commands used to create the power signal of the given frequency and the halyard can be determined by converting the phase angle into the curve for this particular secondary winding and then translating the position on the curve to a certain time meter along the xs0 signal of the signal, for example, indicated by the binary output signal for binary commands 0 A 814. shown below the ordinate of the graph. The high and low levels are taken from the truth table 5.

Signal 814 is a predetermined L-phase binary instruction for the fifth signal 0A. designed to create a 3M wave to promote

0; -. Below the secondary ab; aces through the system along curve 802. It is clear that by shifting by 60 ° (or 1/3 I) or 120 ° (or 2/3) I). from each integer .quantity: l of the primary winding, it is possible to OCR;

5 k-omand of the C-phase and 8-faoi, respectively. In essence, the binary signals C and B are similar to the A-phase signal 814. Except that they are switched off by 60V or 120 to the right, respectively. Also mo, io see that

the signal of the binary A-phase instructions at 8I is constant at the first constant frequency (section 816), is fixed at the changing frequency section 820, and the drift becomes constant, but at a higher frequency at the second constant frequency section 822.

Specific steady state signals, as shown in designation 814 of FIG. 13 for 0A are obtained based on a predetermined position of the secondary windings along the primary winding and a predetermined point in time. Therefore, in order to load the correct instructions into the random access memory of the drive controllers, the following method is used to receive such instructions.

First, the range of motion of the secondary system members is determined. This is also determined by the repeating time interval T between the total circuits of successive secondary windings that move past a fixed reference point in the system. The position with respect to the time profile is determined for all secondary windings of the system, when all the secondary windings only follow the same position with respect to the time profile, changing at time intervals T. After that, it is nice to determine the position with respect to the profile, it was determined to relocate. time for some binary winding of the system at time intervals T. After this determination, for each zone, the phase angle relative to time is determined by (1) selecting the initial phase angle corresponding to the selected position of the secondary winding, before this step winding will go to a certain area; - TPSM provision of the present invention is the position in which the gear; 1 kral of the secondary winding is located at the boundary of the zone, i.e. at the beginning of the transfer; (.) determining from the phase angle with respect to the information of the interval of information of information of length T, starting with the starting phase cenn for the specific zone; and (3) ensuring coordination of the initial phase angle information OTHOCVI-time for a certain zone g with information of the previous zone on phase angles corresponding to the length of the secondary winding, having in mind the length that the secondary winding is needed to completely cross the physical boundary of the zone, but if this is not so, it is necessary to adjust the position relative to the time profile or the length of the zone, followed by the repetition of the above steps. In the described process, it is the third step that ensures that only one secondary winding is present in the zone of the acceleration section at any given time.

After the determination of the phase angles with respect to time for each zone is made, the switching signals of the zone drive device for each zone are determined. This determination is made by (1) encoding the phase angle information relative to the time for each zone into binary switching instructions at discrete points within

the information time interval T2, where (a) the points must be equally spaced and precisely divide the time interval T and (b) the number of points must be the same for all zones, and this number is also equal to the number of memory cells for this type of storage device for all corresponding zone controllers; and (2) placing switching commands for each zone in total

the time interval designated as Tc with; (a) dividing the total time required by the secondary winding to achieve the selected initial phase, which in the present invention is

the beginning of transmission, to the interval T, in order to determine the remaining time for the last whole time interval (b) the beginning of the total time interval Tc from the aforementioned remainder of the time interval T and the display of the switching commands, starting from the start phase commands and continuing to the end of the total time interval Tc, and (c) continuing to display from the beginning of the total time interval Tc the display

the remaining teams, whereby the remaining teams are completed when the start phase is displayed on the teams.

When the system is operating, after performing the above actions, the switching commands of the zone drive devices coming from the memory devices of the zone controllers of a single memory type, RAM X, Y or Z, are simultaneously and continuously synchronized, starting with

the total starting time, which in the invention of the preferred embodiment is at the beginning of the general time interval Tc. This will cause each zone to start and repeat its switching commands for each time interval T for each secondary winding. Now, by supplying the secondary windings to the system at the beginning of each time interval T, their movement of the original

 the system speed will be achieved synchronization of the secondary windings with ZM ROLONA and their correct transfer from one zone to another through the whole system

Referring again to FIG. 13: Not based on the position of a given secondary winding along the primary, the distance of this secondary winding with respect to the adjacent one is always known. Take for example the first secondary winding moving along curve 802: if the leading edge of this secondary winding is at 806, then it is located at a phase angle of 1760 °. The passage from curve 802 to curve 804 dp of the second secondary winding, the line intersects at point 808, becoming the front edge of the second secondary winding and a single angle of 720 °. This means that between the front edges there is a gap of 3 A. Since each secondary winding has a length of Я, the distance between the magnetic boundaries of these secondary windings at this point is 1 Я. Similarly, the first secondary winding, with its leading edge at 810, is located along the 002 bars 6 I ahead of the second secondary winding, the leading edge of which will be at point 812 along curve 804. This increased distance means that the successive secondary the windings are individually accelerated in the respective acceleration zones, independently of the other secondary windings.

A method for changing the first steady state into a transition state and then the second steady state will be described with reference to FIG. 13. When the secondary windings 1 through 10 enter the system, all of them are advancing to the first steady state, as, for example, from RAM X zone controllers, this will be maintained. The validity of this will be maintained until time + UT.

The first and second secondary windings moving through the system along curves 802 and 804, respectively, are affected by only one stable condition of RAM X. The secondary windings 3-11, which move through the system along curves 805, 807, 809, 811, 813, 815 , 817, 8-19, and 821, respectively, are somewhat affected by the transition state stored in the RAM Y of the zone controllers when during transition to + SO the transition state is selected to change the steady state of operation. Secondary windings 12-20 moving through the system along curves 823, 825, 827, 829,831.833, 835, 837 and 839, respectively

of the normal time interval T, and a minimum occurs between the otoric windings 5 and 6 along the curves R09 and 811, respectively. This indicates the changing nature of the windings and puzzles in the speed of the secondary windings. From line 83 to line 834, new steady state velocities are established, but not a single curve has a new slope along its entire length, which indicates that the transition state has a residual effect on these curves. This also means that the time when the next vortex windings leave the system has not stabilized and returned to the time interval T, Until such stabilization is achieved, a completely new condition for the steady state is established. the time of which a second steady state signal from RAM Z can be initialized to energize the primary and advance the fluxes. The separation time between the secondary windings leaving the systems is continuously increasing from the mm between the secondary windings 5 and 6 along curves 809 and 011, respectively, to the time interval Tme / cd by the secondary windings 1 and 13. The ROL of curves 8 and 825coo1 is directly non-immediate after line 834, when initialization of the second steady state occurs. Therefore, as soon as the urine is initialized, the second stable state, the system must be freed from all the secondary windings that are affected by the transition state.

When operating, the random access memory access logic for all zone controllers will act with stable state commands stored in RAM X up to the clock time (824). At this time, the random access memory sampling logic will select transitional suction by selecting RAM Y. The transition state will be in effect from time t + uT at no. 824 to time 1ST at no. 834. That is, the transition state has a programmed operating time of 8G. This programmed time is the time during which all secondary windings affected by the transient state are removed from the system. During tn + 8T, the controller aptsmatically directs random access memory access logic to a choice of RAM Z to enable the system in a new steady state. Working in the stable state for RAM Z, the system computer can reprogram RAM X and RAM Y with new binary numbers

This new programming will provide RAM X with a new stable state, which can be for higher or lower secondary winding speeds.

New programming for RAM Y will be done with the goal of transitioning from the steady state of RAM Z to the new stable state of RAM X

Transitional commands to execute

0 transitions from the first steady state to the second are taken on the basis of a predetermined position relative to the time of each secondary winding, moving along the primary defined by their zones during the total transition time. Below is a method for determining the commands to be loaded into the memory devices with random access transition state of the set zonal controllers to make the transition from the first steady state to the second.

As it was for steady state operations, the secondary windings

5 go to the system with a predetermined time interval T The position relative to the time profile for all secondary windings in the system is initially determined when the transition state is initialized. However, the secondary windings present in or entering the system during the transition state do not follow the same position with respect to the time profile. Thus, to begin with, the relationship between the position relative to the time required for each secondary winding affected by the transition state is determined, taking into account the requirement that only one secondary winding can be in the zone at any given time point. For each position relative time profile for the corresponding secondary

5, the phase angle relative to time is determined. After that, for each zone, the phase angle relative to time is determined by (1) determining during initialization

0 transition state of the secondary winding profile, which is in a certain zone, or, if a certain zone is empty, the profile of the last secondary winding in this zone and creating a phase profile from

5 angles regarding time information; (2) determining from the phase angle with respect to the time information of the predetermined profile, the interval of information starting in the pre-initialization of the transition state, which will be a multiple

the interval T, and extending the interval to the starting phase angle of the first secondary winding entering the zone after the initialization of the transition state, in the same manner as described above for the steady state; (3) determining an isfsa angle with respect to the time information of the profile of the first secondary winding, where the information interval starts from the starting phase angle of this secondary winding and continues until the second secondary winding enters the zone; (A) determining, from the profile of the second secondary winding, the required information, as indicated in the above paragraph 3; (5) continuing the Bt determination process in the above paragraph for each subsequent secondary winding until each end of the transition time interval, denoted by T, which will occur in multiples of the Time Interpol (b) ensures that the phase angle is matched with respect to the time information for each nuric windings entering the zone during the transition state, with information for the same secondary winding and the previous zone, at least at the phase angles corresponding to the length of the secondary winding, having the form the length necessary for the secondary winding to completely cross the physical boundary of the zone, but if it is not, adjust the position relative to the time profile or the length of the zone; (7) encoding the phase angle with respect to the time information for each zone and binary switching commands about discrete points inside the transition information interval Tg, where (a) the points must be evenly spaced and must - | Separate each interval Tg inside the interval Tg and (b ) the number of points should be the same for all zones, and this number should also be equal to the number of transition memory cells for all zone controllers; and (8) displaying the switching instructions for each zone in the total transition time interval Tg, one after the other.

In order to operate in a transition state, the system first operates on a first stable state, and a transition state is selected for all zone controllers at the end of the execution of the last random access memory command of the first stable state. According to the next clock pulse, transient commands are simultaneously issued from all zone controllers with the beginning of the total transition time interval Тг. This forces

all umbrellas1, whose counterintelligence is synonymous with issuing transitional ones; comlnds until their respective random access memory devices are reached in unison at the end of the transition period. When the end of the transition period is reached, the second steady state is selected and initialized. Transitional commands are not

It is also preliminarily that the invention may have a reciprocal side, returning the secondary 5 n.me. windings from the end to the beginning of the elongated primary flashing. In the resulting system, the secondary windings return to the beginning of the elongated primary winding by opposite acceleration of the secondary

This mating side may be a mirror image of the elongated primary winding for the purpose of accelerating the secondary windings, or it may be other appropriate means, which the Court of Justice, “point windings back into the entrance area of the elongated primary OUMOIKH,

In a preferred embodiment, when a mating side is provided that forms an endless loop for the secondary windings, the system of the present invention is particularly suitable for use on stretching or stretching the web

In more detail, with reference, in particular, to drawings 14 and 15, a device or extension frame 901 is shown which

located opposite each other. Both loops 900, 902 are symmetrical — the elements of loop 900 are mirrored in loop 902. Clamping stretch carriages are shown as white dots on a black field, such as carriages 908, 908 in two loops. The carriages advance along the working sides 910 and 912 of the loops 900 and 902, respectively, in polar symmetry. That is, carriages, such as 905 and 908, are aligned along line 914, propended perpendicular to the center of line 904, which is the center line between the working sides of the two loops.

Each contour loop has a number of parts or sections that define the working sides 910 and 912 and the return sides 903 and 923 of the tensile frame. In particular, the first part of the guide tracks defines a transport section 918, where the film is held prior to stretching and is heated at the required temperature without tension.

The second parts of the guide tracks define the key stretch portion 922 of the stretch frame. These portions of a given section generally diverge from the GO outer sides of the lateral line of the machine for stretching the web in the transverse direction.

The third parts of the tracks are connected to the second parts in the front or working portion of the stretch frame. These parts are opposite each other and are remote from the center line of the frame; they define between themselves a stabilizing portion 926 of the device.

These first, third and third parts of the tracks define the working sides 910 15 912 of the extension frame. The tracks end on the return sides of the frame 903 and 923 in fourth parts, where the tension clips are detached from the film. A quarter of the parts connect the first and third parts of the tracks, completing the endless paths. The elongated contour loops 900 and 902 are mounted to move a number of carriages, such as 900. 908 and 940. Extension clamps are attached to the carriages, as can be clearly seen from FIG. 18, which are adapted to grip the edges of the film when it enters the extension frame 901, in order to release the film after it is advanced by the carriage through the working sides. After the film is released, the carriages advance along the return sides of the stretch frame to a position to repeat the stretching operation.

The linear synchronous motor control system of the invention is used to control the carriage advancement.

940 on the working sides of the contour lines 910 and 912, two working sides are connected and installed so as to ensure overall control of each pair of clamps as they move through the stretching section and other working sections.

In a typical application, a web of material or film 961 is formed at the top

in the direction of movement on the designation 916 and is fed to the input of the extension frame at position 920. Extension clips located not opposite pairs of carriages sequentially capture

successive surfaces along the opposite edges of the film at position 920 and advance it at a first constant speed through the transport section 918, where the film is heated. The tracks then diverge, thereby stretching the film in the transverse direction, while at the same time the opposite pairs of carriages are individually accelerated, which causes them to separate from neighboring pairs and

at the same time, it stretches the film in the longitudinal direction at the stretch 922. Heating of the film continues at the stretch to control the temperature of the film during stretching. Then

the tracks become parallel and the individual opposite pairs of carriages reach a final speed at the end of the stretch at 924, and the film stabilizes at 926.

Temperature control of the film continues at the stabilization section. The film is then released from the tension clamps at the exit of the stretch frame at position 929 and goes to a conventional tape drive mechanism. The individual carriages of each loop are then returned along the counterparts 903 and 923 of two endless paths — loops to the input 920 of the extension frame.

If you want to loosen the film or reduce its stress in the machine spout in the stretching or stabilization areas, you can gradually or gradually reduce the speed of the carriages,

controlled by linear motors, in accordance with - any desired program, thereby providing direct control of shrinkage and evenness of the film. It is also possible to weaken in the transverse direction in the stabilization section, which is accomplished by slightly narrowing the tracks of the stretching frame so that the stretching clips move laterally closer to each other.

Groups of coils are adjacent to the secondary windings on the carriages along the working side of the loops. They correspond to zones such as 308, 312, 314 and 423 in FIG. 4, and zones such as Z1, Z4, Z5 and Z10 in FIG. 13-16. Whenever the carriages need to be separated, the control zones are given such dimensions that for a number of the required operating conditions in the control zone there will never be more than one pair of carriages when moving the pairs of carriages symmetrically along the primary winding. However, the carriages in the control zone of the 1st constant speed 930 are closely adjacent to each other at intervals that are a multiple of an integer lmba and move at the same speed, so there can be many carriages in this control zone.

FIG. 18 shows a typical section (Fig. 17) through the working side 910 of the pintle 900. A side view of the carriage 940 is provided. A guide track 942 is provided. It extends along the loop 900 along both the working and return sides, and connects the working and return sides. . The track is supported by fastening to the frame 962. The carriage is mounted on the guide track with eight rollers 944, 946, 948, 950, 952, 954, 956 and 958 that are rotationally mounted on the carriage body 960. The rollers are aligned with rotation and shifted into machine or longitudinal direction (inward of Fig. 18) to provide stable carriage support. In other words, the rollers of the horizontal contour surface 944 and 958 are aligned longitudinally, while the horizontal rollers 946 and 956 are also longitudinally aligned. but shifted or offset from the roller 944 and 958 in the longitudinal direction. Similarly, the rollers of the vertical contour surface 948 and 952 are longitudinally ejected, while the vertical rollers 950 and 954 are also longitudinally drilled, but are offset relative to the rollers 948 and 952 in the longitudinal direction. A different number of rollers or moving elements can be used if the carriage is stably supported for free sliding or rotational movement along the guide track. Additional tracks may be available. The rollers hold the carriage in an exact position on the track and carry loads determined by the weight of the carriage, the voltage of the film 961, clamped by the film clamp, the axial pressure of the motor and unbalanced

magnetic forces between the primary and secondary windings.

A film clamp lever 964 is also attached to the carriage body 960,

connected to 966. The gripping surface 968 is movably mounted on an axis to press the film against the surface 970, which stops the rotational movement. The film is clamped as shown in FIG.

0 18, by pressing on the lever 964 in the direction of the arrow 972, and is released by pressing the lever in the direction of the arrow 974. The upper edge of the lever 964 forms a cam repeating the surface

5,963 and 965, which are controlled by cam surfaces along the guide track. In FIG. 17, the lever surfaces 967 and 969 are moved at the input to clamp the film, and the surfaces 971 and 973 at the exit

A stretch frame moves the lever to release the film. Between the lever 964 and the carriage body 960, suitable resilient assemblies, such as springs, can be connected to hold the clamp in

5 in an open or closed position so that it is forced into the opposite position only under the influence of cam surfaces. Such placement is preferable because

0 cams 967, 969, 971, and 973 must only be set at the inlet and outlet of the extension frame to open and close the clamps. The transverse dimension (inside FIG. 18) of the surface 968 and the forged surface 970

5 is narrow, which allows the film to move freely when it is tensioned between the clamps.

Synchronous secondary windings 976 and 978 are attached at the top and bottom of the carriage body 960. They consist of magnets located at 980 and 982 and transformer iron 984 and 986, like the secondary windings 160 and 170 shown in Figs. 2 essentially magnets in

5, position 980 will consist of one magnet oriented outward by the north pole and a second adjacent magnet located one lbm south of the south pole outward. As shown in

0 FIG. 2, as regards the secondary windings 160 and 170, it is preferable that the secondary windings on adjacent carriages have a reverse arrangement of their psg, wasps. Also, when adjacent carriages have the smallest

5 interval that occurs in the extension frame with adjacent carriage housings, the magnetic boundaries of the secondary windings will have a gap R of one l mba. Go to one klretka. let’s take a leave. that the magnet near the front stsgoni slr mki

the upper secondary winding and the magnet near the front of the carriage on the lower secondary winding will both have the same outward-facing poles. For example, both the upper and lower secondary windings will have north poles near the front of the carriage.

The clamping carriages should go into the entrance of the stretched frame at position 920 with a known interval in synchronism with the EM wave in the first control zone A. Before the machine starts, the carriages are pressed one against the other, the carriage housing is adjacent to the carriage 960, and the first carriage is held motionless, say about 921. This establishes a gap of known constant magnitude at which the magnetic pole pitch of the crate secondary windings is matched with the pole pitch of the EM wave determined by the primary winding coils; in this case, the primary winding is the control zone A. A number of means can be used to press the carriages against each other, for example, linear motor means, conveyor belt means, gravity means, etc. Since the preferred embodiment of the device has carriages with two different polarities, on both working sides, at position 921, an appropriate polarity carriage must be installed. For example, if the starting EM wave requires a north magnet near the front of the carriage at position 921 on the working side 910, then a north magnet is also required near the front side of the carriage 921 on the working side 912. This is true when the magnetic polarity on adjacent carriage secondary windings reversed. Obviously, when such polarity carriages such as these are used, there must always be an even number of carriages on each path so that 3-s and alternate reversal of polarities are maintained as the carriages are continuously circulating in the loops.

After such a pre-launch orientation of the carriages is established, and the rest of the working sides do not have carriage paths, you can start the extension frame - the carriages will advance one after the other along the working sides in synchronism with the EM waves and return on the return sides, as shown in FIG. . 17. If the working side of the stretch frame is stopped under control, the relative positions of the carriages can be maintained so that when restarting the carriages do not need to be aligned again.

At 908 and 990, elongated primary windings are located above and below the carriages, which are divided into control zones. A typical structure of the primary winding is shown in FIG. 2 (designations 182 and 184). It usually consists of coils mounted in grooves between lamellar metal teeth. A predetermined alternating current is supplied to the primary windings through conductors 992 and 994. Using both the upper and lower primary windings provides maximum force to the carriage by simultaneously advancing both secondary windings 976 and 978. In some sections of the extension frame where the maximum force is not required, one upper or lower primary winding can be omitted. However, the upper and lower primary windings provide the carriage with a balanced magnetic force of attraction, therefore, when one of them is eliminated, the load on the rollers vertically arranged on the carriage increases. The primary windings are located in close proximity to the carriage secondary windings, they are separated by only small gaps 996 and 998.

Along the working side of the draw frame, each primary winding includes a number of coil groups, the coil groups of one primary winding being sized to match the coil groups of the other primary winding, and each of the opposite coil groups is electrically combined and defines one control zone. Such control zones are independently controlled and all of their coil groups receive matching or identical drive commands at the same time. In the previous description of the linear synchronous motor system of FIG. 4, for one primary winding, the zone consisted of only a single group of coil windings, which required a zone drive device and a zone controller to independently control this single group of coil windings. The control zone in the description for the stretching frame consists of opposite groups of reel windings.

The control zone for the primary windings of both loops preferably consists of four groups of primary coils. As for the control zone C. including a group of coils 934-934, it consists of a first group of upper coils and a second group of lower coils on the working side 910, as well as a third group of upper coils and a fourth group of lower coils on the working side 912. Groups coils in the control zs:; with C are electrically connected by its zonal drive means 1000. This drive means may consist of one zonal drive device, for example 114, shown schematically in FIG. 1, and in more detail in FIG. 8, or of two zone drive devices, one for the upper and lower groups of coils on each working side, out of four zone drive devices, one for each group of coils in the control zone. The choice of the number of zonal drive devices to be used is recorded by matching power between the power requirements of each group of coils relative to the rated power and zonal drive device. The groups of coils can be electrically connected to the zone drive device or zone drive devices in series, in parallel, or afterburning / parallel, which also depends on the specified power matching. It is important that the zone controller means, such as 1002 dlch of the control zone C, be common to all the zone drive devices of this zone. This zone controller tool may be a single zone controller, as indicated by 132 in FIG. 1 and is shown in more detail in FIG. 5, for reasons of controller capacity, it may be two or more zone controllers storing identical control commands. When in a preferred embodiment, the zonal drive means 1000 consists of a single zonal drive device, the zonal controller means 1002 consists of a single zonal coaster, and coils such as, for example, 146 cc. 1 represent all four groups of coils with a control zone of a stretch frame, then FIG. 1 shows a characterization part of a control system for a linear motor film stretch frame.

It is also necessary to keep in mind that part of the control zone within the same primary coil group, for example, the lower primary winding of the working side 910 of the constant-speed zone A, can be divided into 3–3 subgroups of coils by feeding each subgroup from separate drive devices. However, all zonal drive units will simultaneously receive the same commands from one or more controllers when these sub-function coils operate as one control zone

In the same way that the characteristic control zone C is connected to the zone drive and the means of the zone controller, they are also connected respectively to the zone drive devices 1004, 1006 and 1008 and the zone controllers 1010, 1012 and 1014, typical controllers zones A, B and D, By analogy with FIG. 1, all zone controllers

connected to the central controller

1016, which corresponds to the central controller 108 and the central programmable basic clock circuit of FIG. 1. The central and zone controllers 5 are also connected to a system computer 1018 corresponding to a system computer 100 in FIG. 1. which in FIG. 17 is shown only connected to a central controller 1016,

0 All zone controllers in the control system of the draw frame have a structure corresponding to FIG. 5, and include a first steady state memory, such as 404, to activate

5 of the control zone under the operating conditions of the first steady state; a second steady state memory, such as 412, for activating a control zone under the operating conditions of the second steady state;

0 and a third, transitional memory, such as 408, for activating the control zone to enable transition from the operating conditions of the first stable state to the operating conditions of the second stable state 5. In a stretched frame, this ability to transfer from one operating condition of a stable state to others allows the stretch frame to vary the degree of drawing in the machine direction, the transition from one

0 working degree of continuous stretching to another, not stopping the stretching of the web of material.

The peculiarity of the ability to quickly change operating conditions,

5 i.e. the degree of drawing, for control zones without stopping the advancement of the carriages of the clamps of the extension frame through the control zones, gives the extension frame according to the invention unique possibilities. Firstly, it allows you to start the stretching frame and begin to stretch the film with a low degree of simultaneous biaxial stretching of the first stable state, and then, continuing to continuously stretch the film,

5 move to a higher degree of simultaneous biaxial drawing of a steady state. Secondly, it allows precise adjustment of the degree of simultaneous biaxial PO working time to optimize and achieve previously impossible film quality, since the frames of simultaneous biaxial stretching of the prior art make it possible to perform only discrete changes in the degree of stretching in the machine direction by long and expensive line stops.

During operation, it is also possible to fine-tune and adjust the hood in the transverse direction using discretely adjustable adjusting screws, such as 907, which move the paths towards each other or vice versa. The tracks bend and move at the points of the bend of the trajectories in order to adapt the flame arrest1. Such methods of lateral adjustment are already known. The screws and movably mounted nuts for adjusting the width of the extension frame have a screw segment with a right-hand thread (pos. 911 and nuts 913 and 915} for one of the paths and a screw segment with a left-hand thread (key 917 and nuts 919 and 909) for another path . In this way, rotation of a screw mounted on the axis (for example, 907) will move two paths and opposite directions to each other or vice versa. An engine 905, attached to the screws and controlled by the operator, rotates the screws before and during operation of the stretch frame . Thus, when not bhodimosti can vary the degree of stretching in both the machine and cross nzprEEZleni of x, without stopping the continuous biaxial stretching of the web.

At low degrees of stretch in the machine and transverse directions, film stretching is relatively easy, while at higher degrees of stretch many film polymers, such as polyethylene terephthalate films, often break and break.

After running the film at a low degree of stretching in the machine and transverse directions, using this device it is possible to increase the degree of stretching in the transverse direction by adjusting the width of the stretching frame and in the machine direction by switching the control of the clamps of the stretching frame to the third operating state transition, and the degree of drawing in the machine direction is continuously changing until then. until it reaches a machine-drawn degree of second stable state. Then, the control system can switch the clamp control of the stretch frame to the machine draw ratio of the second stable

states for continuous operation This allows you to run at a high degree of drawing in the machine direction in two axes simultaneously, which was not previously possible in 5 stretched frames of the prior art, because they work with only one fixed degree of simultaneous biaxial machine-drawn hoods which cannot be

0 increased when it is large. High degrees of simultaneous biaxial machine-drawn stretching are those that are superior to 3X or more preferably 5X or even more preferably

5 7X or, in the most preferred embodiment, 9X. This leads to the possibility of simultaneous biaxial stretching of the film, which could not be continuously done earlier with single-stage stretching (single-stage means limiting to the limits of a single stretch of stretching frame).

It can be seen from the foregoing that, in accordance with the invention, it is possible to precisely control the longitudinal elongation of the film due to the use of a number of cage pairs driven by a linear motor, individually controlled independently of other pairs with respect to their

0 longitudinal movement. Therefore, both the simultaneous described dibasic stretching of the I-film can be performed as well as sequential. In sequential stretching to transverse stretching

5 precedes longitudinal and vice versa. If it is required to cross-stretch the film before longitudinal stretching, the speed of the carriages in the diverging parts of the guide tracks is maintained

0 is constant so that only transverse stretching is performed, and after that, in the stabilization section, the speed of the carriages is continuously increased in order to carry out longitudinal film unloading. If this mode of operation is required, the size of some groups of coils shown in the control zones of FIG. 17 should be revised so that when separating the carriages in the control zone, there will never be more than one pair of carriages. In order to stretch the film longitudinally before transverse stretching, the guide tracks in the first part of the stretching section are retuned to continue parallelism, and

5, the speed of the carriages in the parallel portion of the stretch portion is steadily increased to provide longitudinal traction, after which the speed of the carriages is kept constant when the track diverges in the rest of the stretch portion to provide only transverse traction. Moreover, if only longitudinal stretching without transverse is required, the guide tracks 921 to 929 can be kept parallel, thereby not producing any transverse stretching of the film. Similarly, if only transverse stretching is required without longitudinal stretching, the tracks will diverge, as in Fig. 17, but all the carriages will move at a constant speed, not distanced from each other throughout the working area of the stretched frame.

The advantages obtained by the invention essentially arise from elongated stationary primary windings divided into control zones, these control zones act on moving pairs of synchronous secondary windings of linear motors, communicating predetermined speeds to carriages carrying secondary windings and clamps of the stretched frame along the primary windings. Thus, since each pair of carriages moves independently (i.e., precisely moves independently of other carriage pairs), an acceleration program can be defined to superimpose a predetermined, controlled longitudinal extension on the lateral torture. Accordingly, the longitudinal displacement applied to the film as it moves through the stretch portion can be accurately controlled all the time; and you can also precisely control the speed of the film in the transport and stabilizing sections. Whenever it is necessary to separate the carriages, the lengths of the control zone are selected so that at the same time in the group of coils on the primary winding of the control zone there are no more than one carriage. Then, predetermined frequency

and the phase supplied to each zone of the primary winding, any desired stretching of the film can be achieved, such as a variable degree of stretch in the machine direction and a variable ratio of magnitude and degree of stretch of MI-PN within the stretched portion. For example, the strain rate in the machine direction during simultaneous biaxial tension of the film can be controlled in

different positions in the stretch portion of the stretch frame. The deformation rate is determined as follows:

change in unit film length after tension

unit length of non-strained film

 strain in 1 min

The strain rate can be controlled as a constant through all simultaneous tension in the machine direction, or it can increase continuously during simultaneous tension in the machine direction, or it can increase rapidly and then gradually decrease during simultaneous tension. In comparison with the known stretching frames, the stretching frame according to the invention can provide two to three times higher deformation rates, because for any given adjustment of the distance of the machine direction and the deformation rate, the stretching frame according to the invention can act on the working speeds two, three, and sometimes ten times higher than the speeds of any prior art drawbar for uniaxial axial tension. For example, a prior art stretched frame may

X 100% / tension time

provide operating speeds for continuous film exit of only not more than about 500 feet in 1 min. The stretched frame of the invention can provide a working film exit speed of about 1,200 feet per minute. When stretching a film with such an output

a speed and a 5-fold degree of simultaneous biaxial drawing in the machine direction by a distance of about nine feet at a constant speed of deformation in the machine direction resulting from a deformation rate in the machine direction of approximately 32% in 1 min.

To fully appreciate the advantages of the invention, on the extension frame of a linear synchronous motor of the invention

at the same time, polymer films were drawn along two axes in the machine and transverse directions using variable speeds, various degrees of drawing, etc. Hot device known

The uropex techniques provide the possibility of biaxial stretching of the film simultaneously in both directions, but only by stretching the film on the described device did we manage to achieve the remarkable properties of the films of the invention — films that are stretched in two directions absolutely simultaneously in both directions or which are stretched move along two axes, strictly controlled in a predetermined manner.

Thus, films are drawn in both directions at least three times with a strain rate of 10% min to 60,000% / min. Preferably, the films can be stretched at least five times, and in the most preferred embodiments, at least seven and nine times. Films can be any of the following materials: polyesters, for example polyethylene terephthalate-lat and polybutene-terephthalate, polyamides, polyacrylates, polyolefins, for example low and high pressure polyethylene, polypropylene, etc., propylene-ethylene copolymers, polycarbonates, poly nyl chloride, polystyrene, polyurethanes, polyvinyl alcohol, polyvinyl fluoride, polyacrylonitrile, polyamides, copolymers of ethyl and vinyl alcohols, polyphenylene sulfides, copolymers

vinylidene chloride and oiyl chloride and copolymers of ethylene and olefinically saturated monomers such as vinyl acetate, methyl methacrylate, ethyl methacrylate, ethyl acrylate, methyl acrylate, acrylonitrile, methacrylic acid or acrylic acid, and their monomers.

Particularly preferred is a biaxially oriented polyethylene terephthalate film obtained on the device according to the invention and having many good characteristics such as high mechanical strength, very low temperature shrinkage and excellent dimensional stability, which makes it most suitable for use as a base film of magnetic tapes and drives, capacitors, etc. This is especially true for those films which are extruded in two axis five or seven times.
