Abstract: A controlled electronic switch is coupled in series with a load for controlling power to the latter when a main switch is closed to provide a connection to an AC power supply, and an adjustable trigger circuit determines conduction in the controlled switch. Moreover, a shunt resistance is coupled in parallel with the main switch to apply full voltage to the controlled switch when the main switch is open, thus eliminating any sudden voltage transient to the controlled switch when the main switch is closed to a conductive state. The shunt resistance provides sufficient leakage current to the controlled switch to maintain line voltage thereacross although such leakage current is not adequate to operate the load.
Abstract translation: 当主开关闭合以提供与AC电源的连接时，受控电子开关与负载串联耦合，用于控制电源，并且可调触发电路确定受控开关中的导通。 此外，当主开关断开时，分流电阻与主开关并联耦合，以在受控开关处施加全电压，从而在主开关闭合到导通状态时消除了受控开关的突然电压瞬变。 分流电阻为受控开关提供足够的漏电流以保持线路电压，尽管这种泄漏电流不足以操作负载。

Abstract: An electronic device, such as an electronic oven or other device in which electromagnetic radiation is used, has primary, secondary, and tertiary radiation seals for preventing radiation leakage from the device. In one form of the invention a microwave oven has a primary capacitive radiation seal formed between the oven body and the hinged oven door with a secondary radiation absorbent seal in the door about the oven access opening and a tertiary radiation seal including radiation absorbent material in the oven body about the access opening except proximate the hinged edge of the door where the hinge itself forms the tertiary seal.

Abstract: A fail-safe spark ignition system for gas burners includes a spark energy monitoring circuit for controlling the gas valve and bimetal spark gap disabling means for eliminating radio interference. Two circuit arrangements are shown for protection against short circuit failure of rectifiers energizing the gasvalve solenoid or other load from an AC power source, using a second rectifier and a fuse or fusible resistor for circuit disconnection.

Abstract: A control circuit for a self-cleaning oven consisting of a switching system for alternatively connecting the bake and broil elements across the 236-volt powerline to generate heat for normal cooking operations, and for connecting the elements in parallel across the 236-volt line during the self-cleaning cycle. A semiconductor rectifier in series with the parallel-connected elements is utilized to control the rate of heat rise during the cleaning cycle to a predetermined cleaning temperature level, and to further limit power application thereafter. The switching system also controls temperature-regulating components and a safety circuit responsive to abnormal operation of the semiconductor rectifier to interrupt the cleaning cycle.
