Description

The invention relates to a device with a adjustable protective device for protection against light and / or Weather and / or burglary. The adjustable protective organ is particularly suitable for placing on a wall of a building provided on the outside of a window or door and consists for example of a store, in particular a venetian blind or a folding blind or one Roller shutters, folding shutters, sliding shutters or an awning.

Have devices known from DE 197 07 607 A. a venetian blind with slats and one at the bottom arranged, rod-shaped, vertically adjustable end organ. The slats are through flexible connecting elements, namely ribbons or cords, with each other as well connected with an actuator, and can with the the latter can be pivoted into different positions. If such a store lowered to the lowest possible position is, for example, window glazing cover and from the outside not without destroying any Parts are lifted. If, however, a burglar separates the flexible connecting elements, he can the slats move and thereby the behind the store make existing window glazing accessible and destroy it, although this may not be noticed immediately becomes.

Similar disadvantages arise with a folding blind, Roller shutters, folding shutters or sliding shutters or with an awning or similar.

The invention has for its object disadvantages to fix the known devices and in particular to prevent an unnoticed break-in if possible.

This object is achieved according to the invention by a device solved according to claim 1. Advantageous configurations the establishment go from the dependent claims forth.

The protective organ of the device according to the invention has preferably not or only slightly displaceable, first end and a (much more) movable, second End and can, for example, optionally in a cover position or be brought into a release position, in which the protective organ has a designated area, for example at least most of the glazing of a window or covers or releases a door of a building. The The device is also preferably designed such that the two ends of the protective member in the cover position at least approximately immovable. The or at least one sensor element preferably runs at least approximately from the first end to the second end of the Protective organ, preferably depending on the width of the protective organ, two or more transverse to the direction of displacement the second protective organ end at a distance from each other standing sensor elements are available.

The at least one sensor element of the protective organ and the monitoring means together form security means against burglaries. If a burglar tries to get into the cover position and held in this Protective organ, he may be able to open it Damage violence in such a way that the covered Area is at least partially accessible. With more suitable Formation and arrangement of the at least one sensor element However, if or when violence is used, the or at least one sensor element interrupted. The surveillance media then generate at least one alarm signal, for example at least one electrical and / or optical and / or acoustic alarm signal. This will the protective effect of the protective organ against a break-in significantly increased and significantly reduced the risk that a burglar in the area of the security guard went unnoticed into one Building invades.

In an advantageous embodiment of the device are at least a substantial part of the monitoring means and one or each for power supply of the monitoring means and for the generation of any Alarm signal required battery in and / or on the protective device itself, for example essentially in and / or on an existing at the second, adjustable end of the protective member, hollow end organ arranged. The final organ is preferably with at least one of the monitoring means belonging, optical and / or acoustic signal transmitter Mistake. The or each sensor element, the monitoring means and the or each serving for energy supply Batteries can then be completely in the manufacturing plant the device installed in the protective organ and ready for alarm be made so that when installing the protective device in a building or other place of use neither electrical connections nor other measures must be taken to secure the burglary alert. The protective organ is with this configuration, therefore, in relation to burglary protection and generation of at least one alarm signal completely autonomous, i.e. regardless of being away from the protective organ arranged parts.

The monitoring means integrated in the protective organ can in addition to an optical and / or acoustic Signal generator or possibly one instead of one Have signalers to generate an alarm signal and wirelessly, for example by high-frequency, electromagnetic Waves or ultrasound or audible sound or Infrared light or visible light, to one from the protective organ distant, central, for example several different ones Protective organs assigned to alarm device transfer. Furthermore, one for generating an electrical Alarm signal serving, integrated in the protective organ Signal generator through an electrically conductive connection connected to an alarm device remote from the protective organ his. In these cases, the protective organ and its Burglar alarm devices are still partially autonomous.

In another embodiment of the invention The device is the means of monitoring by the protective organ removed, for example at least in part at and / or in an adjusting device used to adjust the protective member, arranged and close to this with the or each sensor element of the protective member connected. The Monitoring means can then be used with power supplies provided and / or connected, for example, to the electrical AC network are connected and / or have a battery. The surveillance means and the Power supplies should be like this in all cases be arranged from the outside of the building and are inaccessible to the facility.

A wall 1 of a part shown in FIG. 2 Building has a window 5 shown in simplified form. This has glazing 7 and borders an interior of the building against its surroundings. One in the figures 1 and 2 visible device 11 has one on the Outside of the window, i.e. in the floor plan on the Surroundings of the building facing the glazing 7 arranged protective element, shown separately in FIG. 3, namely a venetian blind 13 that serves as a curtain a first, upper end 14 and a second, lower end 15. The store has several, for example in essential slats 16 made of light metal sheet, the ends with plastic guide elements 17 are provided. The second, lower end 15 of the store is through an elongated, rod-shaped, hollow end member 18 educated. This has the same as the slats 16 trained lamella 19 and one under this arranged, somewhat simplified also shown in Fig. 4 Profile bar 20. There are at each end of the end organ an end piece 21 and one in the longitudinal direction of the End organ protruding outwards from the end piece Bolt 22 attached. The lamella 19, the profile bar 20 and the two end pieces 21 together delimit one Cavity and close it essentially on all sides against the environment. The lamella 19 and the profile bar 20th of the end organ consist of metallic, non-ferromagnetic Materials, such as light metals. The various parts of the hollow end member 18 and in particular its lamella 19 and profile bar 20 are unsolvable as well as not separable without damage or at least connected with each other in such a way that they can only be Tools and / or only with great effort and time are separable from each other. The lamella 19 and the Profile bar 20 have, for example, interlocking Edges and can additionally at least in places be glued together. The end pieces 21 are for Example in the from the lamella 19 and from the profile bar 20th formed hollow rod inserted, screwed to this and possibly additionally glued to this.

The venetian blind has at least two along the Slats 16 and the end member 18 spaced apart standing, consisting of a one-piece band, at the top End coherent and open loops at the bottom 24 on. The two strands of each loop 24 form a pair of opposing, elongated, flexible, Connecting elements 25 which the slats 16 and that Connect the end member 18 movably. Any fastener 25 extends from the first, upper end 14 to the second, lower end 15 of the store and is by each a holder 26 movable with each slat 16 and the End organ 18 connected. Each holder 26 is a ball joint formed and has two joint parts, of which the one on one edge of a slat 16 or 19 and the other is attached to a connecting element 25. The sidewalls of the profile bar 20 are for each connecting element 25 provided with a hole in which a spout 27 made of rubber or the like is attached. The lower unrelated Ends of the connecting elements 25 are through the Holes of the spouts 27 in the cavity of the end member 18th introduced and fixed in some way in the latter.

A section of one belonging to a loop 24 Connecting element 25 is shown separately in FIG. 5 and has a band-shaped fabric 29 as the main component from electrically insulating, textile threads, for example made of plastic, such as polyamide and / or Polyester. The fabric 29 is near the an edge with one in the longitudinal direction of the connecting element trending, to increase the tensile strength serving reinforcing thread 30. This has a bundle of fibers from under the trade name Kevlar available aramid and at least one essentially completely wound around this fiber bundle, black, as opaque as possible, as light protection serving thread made of polyester. The fabric 29 is in the Proximity to his farther from the reinforcing thread 30 Provide longitudinal edge with a sensor element 31. This extends uninterruptedly along the whole, a pair mutually opposing connecting elements Loop 24 and in particular at least approximately from second end 15 to first end 14 and back to second end 15 of the store. The sensor element 31 has one running in the longitudinal direction of the connecting element, bendable core 32 and a winding around it, electrical conductor 33. The core 32 consists of an electrically insulating thread, for example made of twisted Polyamide and / or polyester fibers. The leader 33 consists of a bundle of fine twisted together or twisted fibers from a well bendable, metallic material, such as stainless steel. The Head 33 forms a helix, the slope of which is essential is greater than the thickness of the fiber bundle forming the conductor, leaving a space between each other following turns of the conductor is present. The single ones, Metallic fibers of the conductor 33 are for example much shorter than the conductor 33 and a connecting element 25, so every metallic fiber just over a portion of the conductor and connector extends. However, it would also be possible for everyone metallic fiber of the conductor 33 without interruption above it extends the entire length.

The conductors 33 of all loops 24 are in the cavity of the End organ 18 electrically connected in series and form together with a loop-like electrical line 34 two ends. The end organ 18 is equipped with monitoring means 35 provided that together with the sensor elements 31 Burglar alarms form, their electrical Circuit diagram in Fig. 6 can be seen. The Monitoring means 35 have an electronic Interrupt detector 36 and a test interrupter 37. The the latter is for example by an electrical, magnetically actuated normally closed switch contact, namely one Reed contact formed. Have the monitoring means at least one signal generator, namely an acoustic, for example piezoelectric signal generator 38, one optical, for example a light emitting diode with integrated Flashing signal transmitter 39 and possibly another in dash-dotted lines in the circuit diagram in FIG. 6 shown radio signal transmitter 40. The monitoring means 35 are electrically conductive with at least one battery 41 connected or provided, for example, only one only battery 41, namely only for the one time Provided, i.e. not rechargeable Lithium battery with a nominal voltage of 9 V and one Capacity or charge of at least or about 1 Ah is available. The battery 41 and the monitoring means 35 are at least substantially in the cavity of the End organ 18. The light emitting diode of the optical signal transmitter 39 may protrude through a hole in the window glazing 7 and the interior wall of the building Profile rod 20 a little from the cavity of the end member 18th out. Furthermore, any radio signal transmitter 40 possibly one that is outside the end organ Have antenna. If a radio signal transmitter 40 is present is a radio alarm signal generated by it in the form electromagnetic waves wirelessly onto one of the venetian blinds 13 removed somewhere in the building, for several Stores common central alarm device 43 transmitted become.

The interruption detector 36 has a semiconductor switch 45 with a Darlington transistor circuit 46. This has two or more bipolar npn transistors integrated in a common housing, has three connections and is shown schematically as an npn transistor. The line 34 is electrically conductively connected to the Darlington transistor circuit 46 at two connection points. One of the ends of the line 34 and the negative pole of the battery are in fact directly connected to the emitter of the Darlington transistor circuit 46 and to the ground connection of the entire monitoring means 35 and, for example, to the metallic parts 19, 20 of the end element 18. The other end of line 34 is connected to the base of transistor circuit 46 via test breaker 37. The base of the transistor circuit is also connected via a resistor 47 to the positive pole of the battery. The collector of the transistor circuit is connected to a coil of a relay 49 via resistor 48. The relay 49 has a make contact which, in the closed state, connects the positive pole of the battery to the signal transmitter, so that the relay serves as an electrical signal transmitter. The Darlington transistor circuit 46 has a current amplification _factor h _fe of at least 20,000 and for example at least 30,000. The Darlington transistor circuit can consist, for example, of the transistor circuit available under the designation BC517 (Motorola). The large current gain enables a resistor 47 to be used, the resistance of which is at least 1 MΩ, better at least 3 MΩ and, for example, approximately 4.7 MΩ. The use of a Darlington transistor circuit with high current amplification and a high-resistance resistor 47 makes it possible to keep the current flowing through this and the interruption detector very low when the line 34 is intact. The current consumption of the line 34 and the entire monitoring means 35 is at most 10 μA, preferably at most 3 μA and, for example, at most or approximately 2 μA in the off state of the transistor circuit. The battery 41 can then keep the monitoring means in operation and ready for alarm for a period of at least 5 years and for example at least or about 10 years, without the battery having to be replaced or recharged or without any power being supplied from outside.

The device 11 has two on the wall 1 of the Fixed vertical guides 51 with a building Profile bar. Each slat 16 is at its ends with the Guide elements 17 vertically displaceable and around a horizontal Axially pivoted in the guides 51. The end member 18 is horizontal by the bolts 22 Axis pivotally connected to two sliders 52, of each of which is vertically displaceable in one of the guides 51 is led. An actuator 55 has one in the upper ends of the guides attached to the wall 1, against bottom open support channel 56, which is a rotatably mounted Contains wave 57. This is through a drive device 58 rotatable, for example a manually operated Crank. Each slide 52 is characterized by an elongated, transmission element arranged in one of the guides 51, namely a toothed belt 59, with one on the shaft 57 seated gear 60 connected. In the support channel 56 is for each pair of opposing fasteners 25 a turning device 61 which can be actuated by the shaft 57 available. The fasteners 25 of each loop 24 are near their top, contiguous ends by short, particularly clearly visible in Fig. 3, such as additional connecting elements having cords or the like 62 with the associated turning device 61 connected so that the slats 16 so with the connecting elements 25 and additional connecting elements 62 suspended are. For each loop 24 there is an upper one End penetrating holding member 63 and one immovable part of the loop concerned assigned turning device 61 and / or directly on Support channel 56 attached. The holding member 63 has Example a rigid, metallic bracket or a Wire rope on, allows limited movements of the by the Loop 24 formed connecting elements 25 and is trained and attached so that it and its Connection with the support channel a greater strength than has the loop 24. The additional connecting elements 62 and Holding members 63 are completely within one arranged at the top of the window, not drawn, also containing the support channel 56, against bottom open storage box so that it is from the outside of the building are practically inaccessible. The Adjustment device supports the external venetian blind and enables this to adjust in the usual way, i.e. to lift or to lower and the slats 16 and the end organ around to pivot horizontal swivel axes.

If the store - as shown in Figures 1 to 3 - is lowered to the lowest possible position, all Slats 16 carried by the connecting elements 25 and in Distance from each other and from the end member 18. The Slats 16 and the end member 18 are in Figures 1 to 3 drawn in an open swivel position in which it is still let in a lot of light. By turning the shaft 57 can the slats 16 and the end member 18 via the turning devices 61 and the connecting elements 25 in one Closing swivel position can be pivoted in the overlap each other. The store moves into the cover position in which the store the glazing 7 at least covers almost completely and without gaps. The end organ starts when swiveling into the closing swivel position from its open position drawn in FIG Swiveled clockwise. The main radiation direction or Radiation axis of the optical signal generator 39 is then directed obliquely upwards against the glazing 7.

The lower, second end 15 of the venetian blind can through Rotation of the shaft 57 starting from that in FIGS 3 drawn position can be moved up, whereby the first, upper end 14 of the store raised a little at most and the store is gathered in the usual way. In the the highest possible position, the store takes a release position one in which he has at least most of the Glazing 7 releases.

The adjusting device 55, the connecting elements 25 and the transmission elements 59 are designed such that they all slats 16 and the end organ 18 in the Cover position of the store cannot be moved and cannot be swiveled hold tight. So it is not possible to get the store from to lift the outside of this and the building without destroying anything. However, if a burglar is under Use of violence tried the whole venetian blind or at least part of this away from the support channel 56 to tear down and / or slats 16 away from each other as well for example at least in part away from the end member 18 Moving up is practically inevitable at least a loop 24 forming a pair of connectors 25 in at least one place and probably mostly in two connecting elements belonging to the loop interrupted. This will cause at least one of the Sensor elements 31 and its conductor 33 interrupted.

The electrical resistance of line 34 is very high much smaller than the resistance value of resistor 47. If line 34 is intact and the test breaker is closed, the base and emitter of the Darlington transistor circuit 46 therefore practically on the same potential. The transistor circuit is located then in the blocked state and the make contact of relay 49 is open. If at least one of the Sensor elements 31 and thus line 34 interrupted the Darlington transistor circuit gets into the Control state, so that the closing contact of relay 49 is closed and the signal generators 38, 39 electrical alarm signal, i.e. an electrical voltage feeds. The two signal generators 38, 39 then generate in turn an acoustic or visual alarm signal, for example a whistle or a sequence of colored ones or white light pulses. If the end organ 18 also has a radio signal transmitter 40, this generates a electrical formed by electromagnetic waves Radio alarm signal and transmits it wirelessly to the central Alarm device 43, which is then also acoustic and / or generate visual alarm signals and / or a police station or alert another surveillance service can. Otherwise, the signal generator 38, 39 and the possible signal generator 40 after the triggering of a Alarms continuously alarm signals until the battery 41 discharges or until someone opens the end organ 18 and the Monitoring means 35 puts out of operation. Because the monitoring means 35 and the battery 41 at least in arranged substantially well protected within the end organ 18 and especially in the cover position of the store completely inaccessible from the outside of the housing are, it is almost impossible for a burglar to do that To put alarm security devices out of operation without first to trigger an alarm.

The formation of each conductor 33 by a helix stainless steel fibers ensure good flexibility the conductor, so that this by the when adjusting the Venetian blind deformations of the sensor elements not be broken. The leaders are also steadfast against weather influences and therefore permanently.

The test interrupter 37 connects the line 33 normally conductive with the break detector 36 and is arranged in the hollow end member 18 that it with a small permanent magnet through the wall of the end organ can be operated without contact and the connection the conductor 33 with the interruption detector 36 temporarily interrupts. If the monitoring means and the If the battery is ready for alarm, then alarm signals generated. The interrupter 37 thus enables control the battery and the function of the monitoring means.

If the battery due to a long installation time and / or discharged as a result of an alarm process , it can be carried out by specialist personnel from the manufacturer of the Facility to be replaced, possibly the whole End organ 18 is replaced.

The facility 111 has a venetian blind 113, the slats, as a protective device 119, has a hollow end member 118 and loops 124, each of which is a pair of elongated connectors 125 forms. Each loop 124 in turn consists of an integral piece Band, but is at the top of this facility Open end and contiguous and penetrating at the lower end holes at the lower end with grommets End organ profile bars 118. Each connector 125 is provided with a sensor element 131, which is an electrical Has conductor 133. The store is through a Adjusting device 155 adjustable, the carrying channel 156 having. The monitoring means 135 are at this facility not in the end organ 118, but from the venetian blind 113 arranged away. The heads 133 of the various connecting elements facing each other in pairs are near the top ends of the fasteners 125 and actuator 155 electrically in series switched and together form a line 134 which with the interrupt detector of the monitoring means 135 connected is. The break detector as well acoustic signal generator of the monitoring means 135 and associated with and / or belonging to these Power supplies are, for example, at Actuating device 155 on the inside of the building Long side of the support channel 156 in the already mentioned not drawn storage box, so it from the environment of the building are practically inaccessible. The Power supply means have one, for example the AC power supply connected as well as at least a rechargeable buffer battery or one Accumulator. The monitoring means 135 still have at least one optical signal generator, for example is arranged so far from the support channel 156 that it Light in the room behind the glazing 7 of the building shines. The relay of the break detector and / or an additional electrical signal generator Monitoring means 135 may also be by electrical conductors with a relatively far from the store and from the Monitoring means 135 removed for multiple stores common, central alarm device. The from the AC network to the monitoring means 135 and this to an alarm device remote from the store leading conductors are shown schematically by arrows in FIG. 7 indicated.

Each connecting element 25 and 125 can by one 8 connecting element 160 be replaced. This in turn is band-shaped and has one fabric and two in the longitudinal direction of the connecting element 160 running sensor elements 161, of which each similar to the sensor element shown in FIG. 5 31 and one designated 163 in FIG. 8, has electrical conductor. The opposing ones Fasteners can in turn be through dreams be formed in one piece and at the top or lower end related. The two leaders 163 can be electrical at one end of the loop, for example conductive with each other and at the other end of the loop Conductors from other fastener loops and / or be connected to the interruption detector.

The light guides of the different For example, loops are optically connected in series and connected to monitoring means. The surveillance means are trained to work with at least one To generate light source continuously or in pulses as well as through the light guide and with one having at least one optoelectronic element Interruption detector in the event of an interruption in the light line to trigger an alarm.

The sensor element 181 shown in FIG. 10 is elongated, limited a free, close to the environment closed cavity for receiving a fluid and consists, for example, of a thin, easily bendable Tube. For example, there can be several, in pairs Connection elements forming loops, each with at least be provided with such a sensor element. In the various connecting elements arranged sensor elements 181 are connected to each other, for example that they are sort of connected in series and together form a continuous line with one end Monitoring means connected and at the other end, for example is completed. The monitoring means have, for example one connected to the cavities of the sensor elements Fluid source to the cavities of the sensor elements a fluid, for example compressed air or another Gas with a pressure above the ambient air pressure feed. The monitoring means can then also one Interrupt detector with a pressure switch, the in case of an interruption of a sensor element in an electrical alarm signal caused this change in pressure generated.

The sensor elements 171, 181 according to FIGS. 9 and 10 may have a core around which the Light guide or the one that delimits a free cavity Hose helical and analogous to the conductor 33 around the Core 32 run around.

The protective device can also consist of a venetian blind, where there is little or no movement, first end below and the widely sliding second end and the end organ at the top of the store. The first, lower end of the store can then, for example, be constantly in are held in a recess in a window parapet, while the one at the second, upper end of the store End organ vertically displaceable by the adjusting device and is pivotable. The slats of this venetian blind are hung with fasteners on the end organ and can by lifting, lowering and pivoting the end organ as well be raised, lowered and swiveled. The Venetian blind takes in the highest possible position of the end organ the cover position and in the lowest possible position of the end organ the release position. The support elements are provided with sensor elements that are in a of the types described above and trained with monitoring means are connected. The latter can, for example analogous to that shown in Figures 1 to 7 Facilities at least to a large extent in the End organ or be arranged in the actuator.

Furthermore, a device with a horizontal sliding venetian blinds are provided, the slats, a first end that cannot be moved or can only be moved slightly, a horizontal, for example, about the width of the Glazing of a window slidable by an end organ formed second end and elongated, flexible Has connecting elements, which from the first to the second End of the store and the slats as well as the end organ connect with each other and with an actuator. When the fasteners are stretched, they run with this variant of the store not from bottom to top, but horizontal. The connecting elements are the same as in the previously described devices with sensor elements provided that associated with monitoring means are.

The device can be used instead of a venetian blind different type, provided with at least one sensor element Protective device, for example a folding blind, roller shutters, Folding drawer, sliding shutter or an awning or the like exhibit. If the protective device comes from a roller shutter or Rolling armor exists, the actuator has a shaft and / or roller for winding and unwinding the roller shutter. The Roller shutter has a little height adjustable with which Shaft and / or roller connected, first end, one more Height adjustable, normally in the cover position second end below, a number of fixed Rods and at the second end a rod-shaped, possibly hollow Final organ. The rods and the end organ are through joints and / or elongated, flexible connecting elements, for example Belts or the like with each other and the shaft and / or roller connected. If the roller shutter all bars and the end organ connecting, flexible, made of belts or the like has existing connecting elements, can do this similar to the described connecting elements the venetian blinds are provided with sensor elements. If the roller shutter has no such connecting elements, can elongated, flexible sensor elements in any a way on all bars as well as the end organ of the shutter and possibly additionally on the shaft and / or roller be attached.

If the device as a protective device an awning owns, this can be the main component of a fabric exhibit. This is at the first end of the awning with a Shaft and / or roller connected to an actuator. At the the other, second end of the awning is a rigid, elongated, rod-shaped, possibly hollow end organ on the fabric attached.

Furthermore, the ladder possibly with an electrical coaxial to them insulating jacket. If the protective organ like the venetian blind 13 through flexible transmission elements 59, for example toothed belt, with the adjusting device is connected, these transmission elements can possibly can also be provided with sensor elements. in the the rest of the protective device can instead of a window be arranged on the outside of a door.

The Darlington transistor circuit can be pnp transistors instead of npn transistors, where then the battery with the reverse Polarity is connected to the transistor circuit. Furthermore, the interruption detector 36 and the signal generator 38, 39, 40 possibly by two or more separate batteries can be powered. The Monitoring means 135 of that shown in FIG. 7 Device 111 can instead of from the AC network also only from at least one battery with electricity be supplied, the battery can only be discharged once or can be rechargeable. Furthermore, the relay 49 by one of the Darlington transistor circuit 46 controlled semiconductor switch to be replaced.

Monitoring means with a Darlington transistor circuit and approximately according to FIG. 6 Trained circuit diagram can also be used for monitoring at least one electrically conductive sensor element provided that is not in a venetian blind or other protective organ of the type described is arranged, but possibly with one arranged in a protective organ Sensor element is connected in series, but not absolutely must be. For example, there can be at least one Sensor element can be provided in a window or a door of a building or possibly a vehicle is arranged and when the window is opened violently or the door is interrupted. Such a sensor element can have, for example, a thin conductor which is arranged in such a way that when the window is opened or the door is torn. Such a sensor element can also an electrical switch contact, namely one Have normally closed contact that is normally closed and when opening, especially when opening by force, a window or door leaf is opened. If more such sensor elements are present, they can be electrical be connected in series and together a line form their ends with the Darlington transistor circuit are connected. Such low power Monitoring means are also for example Holiday homes without connection to the AC network or also for securing doors and / or windows from Suitable vehicles and the like and can then from at least one battery supplied with electrical current be, the or each battery can only be discharged once or be rechargeable.

Finally, we will refer to the one already quoted DE 197 07 607 A and the Swiss patent application 1664/97 and the corresponding European patent application 98 810 612, the content of which is hereby incorporated into the the present application is included, insofar as none Contradictions arise.
