    • A self-contained electronic wall switch actuator can easily be mounted directly onto the outside of the face plate of an ordinary wall switch. When so mounted, the actuator engages the wall switch's actuating lever and permits the automatic actuation of the wall switch by way of simple touch action: (i) by lightly pressing a Bypass Key, the wall switch is caused to reverse its state from ON to OFF, or from OFF to ON, whichever is appropriate; (ii) by lightly pressing a Delay Key, the wall switch is caused to enter its ON-state and to remain there for a presetable first period of time; and (iii) by lightly pressing a Cycle Key, the wall switch will, starting right then and repeatedly every 24 hours thereafter, enter its ON-state for a presetable second period of time.The actuator comprises a small battery, a miniature electric motor with a gear/linkage mechanism operable to engage with and to move the wall switch's actuating lever between its OFF and ON positions, and a quartz-clock-based programming means.

    • A circuit for disengaging an electrically actuated transmission brake of a racing car has a bank of transistors in series with the brake to hold the brake on at the beginning of a race. The bases of the transistors are connected through normally open contacts of a relay to the emitter of a transistor that can be turned on or off by an optoisolator and the brake is connected through diodes to the relay coil to isolate the transistor bases once the brake has been disengaged. The optoisolator is connected, through diodes, to the zero count terminals of two clocked, programmable counters either of which will turn the optoisolator off at the end of a count. Reset terminals of both counters are connected to the outputs of a flip-flop to disable one counter and toggling of the flip-flop is effected by closing normally open contacts of a second relay to complete a circuit between the flip-flop input and a voltage regulator output through a Schmitt trigger. The second relay contacts are also connected to preset enable terminals of the counters to enter preselected numbers into the counters and prevent counting while the relay is energized. The relay is energized by closure of a starting switch connected between the second relay coil and the car battery so that release of the switch will enable one counter to provide a preselected time delay in the release of the brake.

    • A conveyor system for delivering work pieces to a predetermined area comprising a first conveyor, a second conveyor disposed at an angle to the first conveyor, a mechanical brain, and a transfer apparatus (arm) at the juncture of the first and second conveyors. The mechanical brain has a shim, a rotating disk and sliding plates on the disc that are temporarily moveable to form a protrusion that rotates with the disc. The disc rotates at a speed that is a function of the speed of the first conveyor and the protrusion activates a device to create a light path transverse to the first conveyor near the first and second conveyor juncture just prior to a workpiece entering such juncture. The protrusion is returned to its normal state, subsequent to the creation of the light path, by the coaction of the rotating disk and the shim. The workpiece interrupts the light path causing the transfer apparatus (an arm) to divert the workpiece to the second conveyor and upon the reestablishment of the light path, the arm is caused to retract.

    • Electric power switch housed in a housing B, operated manually by a toggle or button I and connected to ends V and W of an electric power cord supplying power to an electrical appliance or apparatus. In the housing B there is a built-in cyclical electronic control timer which when the commutator S is in the "stand-by" position continously stores during a gliding period of time (cycle) the schedule of sequences of on/off power switchings, as commanded by the user by operation of I, into an electronic memory. When the commutator S is in the "simulation" position, operation of the electric power switch is taken over by the electronic control timer, which implements power switchings cyclically and indefinitely according to the schedule of sequences of on/off power switchings stored in said memory during the cycle immediately preceding the transition from the "stand-by" to the "simulation" mode of operation and as long as the commutator S stays in the "simulation" position.
