  • Patent number: 4376896
    Abstract: A switching assembly to be incorporated in a window-regulator for a motor vehicle and the like, which includes paired units of switching members, each of which is arranged to serve for operating an electric motor in either of two rotational directions in a manual mode or in an automatic mode subject to the displacing amount of a single switching knob, and an electric circuit means including a solenoid for selectively self-retaining and self-releasing the automatic operating mode. The switching assembly is arranged to be capable of selectively energizing and de-energizing the electric motor incorporated in the window-regulator together with operating the solenoid simultaneously.

  • Patent number: 4376895
    Abstract: An electromechanical switching device has a housing containing an armature. This armature is mounted in the housing to reciprocate between a closed and an open position. A coil mounted near the armature in the housing can magnetically hold the armature in its closed position. A manually operable member is mounted in the housing to reciprocate between a set and a reset position. This member can be moved into the set and reset positions to drive the armature toward its closed and open positions, respectively. Being arranged in this fashion the coil can be operated by a relatively small current. This current may be insufficient to attract the armature from its open to its closed position. However, the full travel of the armature is accomplished by the combined effects of the manually operable member and the coil.

  • Patent number: 4362954
    Abstract: A microprocessor controlled appliance is provided which has a smooth unbroken control surface. A control panel assembly includes a support panel and a decorative panel overlying the support panel. The assembly further includes a continuous flexible membrane layer. The support and decorative panels each include a generally aligned opening providing rear communication with the flexible membrane layer. A power source provides power between a pair of electrical conductors for energizing the appliance. A manually-set electrically-reset switch is associated with one of the conductors and is mounted to the support panel below the flexible membrane layer. The switch is manually operable to a closed position by depressing the membrane layer through the opening to complete a circuit across the pair of conductors for powering-up the microprocessor controlled appliance. Mechanism is provided for holding the switch in the closed position including a portion engageable with the switch.

  • Patent number: 4326133
    Abstract: A control circuit for alternately actuating a pair of loads includes a voltage doubling circuit having a capacitor common to a pair of charge storage devices and switch means which are alternately actuated to discharge the charge storage devices through a pair of loads. Coupled to the circuit is a holding current power supply for maintaining the loads in an actuated position once the charge storage devices are discharged. The circuit thus provides an initially high current pulse for rapidly actuating inductive loads such as solenoids.

  • Patent number: 4323762
    Abstract: Apparatus for disconnecting electrical powered devices from a source of electrical energy when the use of the devices is no longer needed. The apparatus includes an electrical switch movable in response to an actuation member. The switch is connected between a source of electrical energy and an electrical powered device so as to selectively connect/disconnect the device to the source of electrical energy depending upon the use of the actuation member. A second electrical switch, also responsive to the actuation member, is connected between the source of electrical energy and another electrical powered device, such as a heating/air conditioning unit, to connect/disconnect the heating/air conditioning unit to the source of electrical energy. One temperature responsive device is associated with the second electrical switch in order to maintain the room temperature above a predetermined minimum temperature.

  • Patent number: 4303836
    Abstract: A silencer adapted to suppress the audio output of a radio or television set during commercial breaks in a program. The silencer which requires no wiring changes in the set includes a probe insertable in the existing earphone jack. The probe is constituted by a truncated tubular plug whose length falls short of the flexible switch arm of the jack that normally engages a contact arm to connect the audio signal line to the loudspeaker, the plug having a retractable plunger therein. When the plug is advanced by a local actuator, it engages the switch arm of the jack to flex it away from the contact arm to cut off loudspeaker sound, the sound being restored when the plunger is retracted. The local actuator of the plug is coupled to a remote actuator which when manually-activated acts selectively through the local actuator to advance or retract the plunger to cut off sound at the outset of a commercial break and to restore it at the conclusion thereof.

  • Patent number: 4249089
    Abstract: The control portion of a television receiver includes a flip flop which when supplied with operating power stores a binary signal having either an "on" level corresponding to the on condition of the receiver or an "off" level corresponding to the off condition of the receiver. In addition to a user responsive input arrangement for selectively controlling the level of the binary signal, a switching circuit is coupled to the flip flop to return the binary signal to its prior level after power line dropouts having less than a predetermined duration, and otherwise causing the binary signal to have its "off" level. The switching circuit is rendered operative at the end of power line dropouts to cause the binary signal to have its "on" level if an enabling signal selectively developed by a circuit including a capacitor and a diode connected between the flip flop and capacitor during the presence of operating power is still stored in the capacitor.

  • Patent number: 4185208
    Abstract: The circuit breaker is taught with an anti-pumping control circuit. If the circuit breaker closes on a fault and quickly reopens without the closing switch being either mechanically or electrically released in the interim, reclosure of the circuit breaker either by an automatic reclosure or by the mere fact that the closing switch remains closed will be prevented until the closing switch is once again opened. In addition, if the closing switch is actuated prior to power being applied to the circuit breaker control system, the circuit breaker will not close when power is applied. The closing spring will be charged, however, for a subsequent circuit breaker closing after release and reactuation of the closing switch.

  • Patent number: 4002956
    Abstract: Apparatus for the prevention of theft of electrical appliances comprises an automatic electronic lock off system which may be activated in a particular manner after the appliance is connected to a source of electrical power, and which becomes deactivated when the appliance is disconnected from its source of power to cause the further disconnection in the appliance electrical circuit. The apparatus comprises essentially three components, a key-operated activator switch, a relay, and the appliance's own on-off switch, all connected with the appliance's own circuit leads in a particular manner. The key-operated activator switch is designed to be operated with its own individual key and may, if desired, be hid from view. Initially, the key-operated activator switch is briefly closed to complete a circuit with the coil of the relay. Activation of the relay closes a normally open switch in series with the appliance on-off switch to permit the appliance then to be operable.
