"Time sequence switch"

The priority of U, SA patent application No. 468 699 of July 1, 1965 is claimed for this application.

The invention relates to a time sequence switch that is used for Control of various programs can be used.

The present invention makes this general today The usual mechanical escapement is replaced by an electronic circuit that connects to other mechanical and electrical ones Parts of the timer work together to generate timed electrical pulses that drive the drive motor energize the time sequence switch and in this way a step-by-step activation of the time sequence switch by a through the programmed timing.

in the application of the hitherto customary mechanical Henimvverke canceled, such as the following:

Mechanical inaccuracies or malfunctions reduce the service life of the switch, the designer must select a certain step time interval of the escapement and consequently the later one Operation of this switch generally at only this one selected step time interval or multiple limited by this, the size of the angle of a switching step is limited and one is forced to to keep very tight tolerances with regard to the switching angle «,

By using an electronically generated time interval According to the present invention, these disadvantages or limitations in the applicability of a time sequence switch become eliminated. The present invention is also particularly beneficial in that the lack of agitation Parts leads to an extension of the service life and also several components of this electronic circuit one exercise double function and because finally the resetting of the timer circuit and the program sequence through causes the drive motor only by a single, normally open contact of the timer switch can be. No further justification is required for the fact that electronic components, as they are according to the invention are used, work much more reliably than the mechanical parts that are made by these electronic

Components are replaced.

As an electronic circuit generates a controlled interval, the usual timer motor, which was required to drive the mechanical escapement, can be omitted specific starting point of the time program towards reasonable M are exaggerated.

Another major advantage results from the fact that now the variable time interval that is generated by the electronic Circuit according to the present invention has been generated, can be changed simply by adding a the only resistance within the timer circuit is adjusted. The time series switch according to the invention is therefore extremely adaptable in terms of the timing of the set programs. If necessary you can for it ensure that the time sequence switch automatically has a certain Resistance repeatedly selects and thus a different time interval for different sections of the programmed timing

Eint bypassing the electronic circuit that controls the Generated time intervals, enables an extraordinary rapid continuation of the time sequence switch in the off position for a specific switching program or for

Omission (skipping) of a circuit program corresponding control of the drive motor.

The amount of the angle feed of the time sequence switch is mechanically determined by the shape of a control cam, and this angular feed is within the range adjustable from zero to 360 »part of the drive motor the camshaft is only operated intermittently, ™ is its expected service life compared to that of Motors in the time series switches still common today

Vieil now a direct motor drive is used for the rotation of the camshaft of the timer and also for overcoming any external load Available energy is no longer necessarily due to the size of the timer motor and the mechanical Ilemmwerk fc limited; the output torque is now only from the Depending on the number of the motor and the reduction gear.

A particularly advantageous feature of the present invention is that there is now only one control switch in the process the step feed is required. This single switch interrupts the engine and also sets the Zeitgeberstronikreis back to the starting position »There is still several other components within the scope of the invention Time sequence switches that perform a dual function as required for the correct operation of the switch.

Zeitfoli, eschalters according to the invention described in detail. The current flowing through the motor 11 is due to the high resistance of the circuit on the output side of the Bridge rectifier 20 limited to a very small value «Since the motor current is very low, the Motor 11 does not start. After the timer circuit 21 has run through a period, it provides an output pulse to the cathode-gate connection of the silicon-controlled φ rectifier 34, which is now this silicon-controlled Rectifier 34 ignites, over rectifier 34 remains this ignition continues to be switched on because the capacitor 27 through the parallel to the silicon-controlled rectifier 34 and the I; resistance 35 removed voltage is sufficient is charged vtorden to the silicon controlled rectifier 34 during the period in which the Load current for this purpose does not bother to provide a through current. After cer silicon controlled rectifiers 34 has been switched on, the resistance drops of the stepping circuit 22 to a very low value and maintain this value until the rectifier 34 is switched off by closing the switch 30 and until the switch 36 is also opened sufficiently has been. When the resistance of the stepping circuit is low, the motor 11 has almost all of it Mains voltage so that sufficient current flows through the motor and it starts up.

Shift lever 36 operated to reset the sensor circuit 21. \ ienn the contact lever 36 is lifted again, the motor 11 is switched off and the encoder circuit 21 starts the time sequence again. The time sequence switch has now run through a complete time interval. The time lying between two intervals depends on the period of the ^ eitgeberkreises and from the rotation angle of the cam shaft 19 of the timing switch off which in turn through the fi cam plate 37 and is determined by this actuated contact arm 36 _o By changing the Viderstanüswerte of the variable resistor 18 within the Timer circuit 21, the time interval of the switch can be changed from one see "to three minutes"

ftenn the motor 11 (latch circuit later) is turned on by other circuits than the bridge rectifier 20, the ^ eitgeberkreis 21 and the step circuit 22, etc. is obtained a very rapid further rotation of the motor 11 up to a certain starting point of a timing program or it is also possible to skip of a complete program. This rapid advance can be impressed as a coded value on the cam switching device, for example by automatically skipping certain sections of the switching time program.

The switch according to the invention is a novel combination in the sense that several of the components assume dual functions and thus the entire arrangement is particularly simple

Thus, in one case, the motor 11 acts as a load and he in the other case limits the diode current of the diodes 23bis to a value below that for which the diodes are dimensioned. The capacitor 27 acts both as a filter as well as the electricity supplier for the rectifier 34 «Die Diodes 23 to 26 both supply a high voltage direct current for the timer circuit 21, and they allow

φ an alternating current flow to the drive motor 11 in time, with only a single control rectifier 34 being present. The single cam-controlled switch 36 causes the Motor 11 continues to run after rectifier 34 has fired and it also puts timer circuit 21 back on Initial state back. The bridge rectifier 20 can obviously also by some other rectifier circuit be replaced, which ensures double rectification of an alternating current and the timer circuit 21 as well
