Abstract

Input terminal 10 receives a triggering impulse from an electrical component to be timed, such as cam-operated contacts, to fire strobotron 15. In some instances, it is desirable to fire 15 as soon as the contacts are closed. At other times it may be desirable to wait until some other event takes place in response to the closing of the contacts, such as the pickup of the armature of a magnet.

Strobotron Circuit

Input terminal 10 receives a triggering impulse from an electrical component to be timed, such as cam-operated contacts, to fire strobotron 15. In some instances, it is desirable to fire 15 as soon as the contacts are closed. At other times it may be desirable to wait until some other event takes place in response to the closing of the contacts, such as the pickup of the armature of a magnet.

Input 10 is connected to a latch 20 and a selector switch 21. The output of 20 associated with the set side is connected to the input of a delay circuit 22. The period of delay can be varied as desired over a given range. The output of the delay circuit is connected to the reset terminal of latch 20. The output of latch 20 associated with the reset side is connected to a transformer 23 for firing the strobotron 15.

The switch 21 is a manual switch having open and closed positions. When the switch 21 is closed and there is an input, the latch 20 is switched. The resulting output is then delayed by the delay circuit 22 and resets the latch 20. The resetting of the latch effects an output to transformer 23 for firing strobotron
15. Hence, in this instance, strobotron 15 fires at a predetermined time after the closing of the electrical contacts.

When the selector switch 21 is open, the latch 20 does not function. A signal to input 10 applies an output signal directly to transformer 23 to fire strobotron 15 immediately.
