Abstract: BALANCED AREA SAFETY VALVE            Abstract of the Disclosure A single line surface controlled, subsurface safety valve, adapted for connection in a well tubing string.  The safety valve has a closure means disposed in the bore of the safety valve housing and is operable by action of control pressure fluid causing a longitudinal operator to move the closure means to an open to flow position.  The control pressure fluid cham-ber in the safety valve is protected from well pressure by providing annular areas, between the longitudinal operator and the housing, positioned between the control pressure fluid chamber and well pressure.  The annular areas are sealed from exposure to well pressure and are in fluid communication with each other.  A floating piston is positioned to respond to well pressure entering the annular areas and thus move to engage and assist the operator means in closing the safety valve to flow of well fluids therethrough.  Vent means is provided to prevent a hydraulic lock from retarding movement of the floating piston.

Abstract: CONTROL APPARATUS FOR HEATING APPLIANCE                 Abstract of the Disclosure A control apparatus for a heating appliance, such as a microwave oven, uses a microcomputer as its control means.  A power switch for supplying power to heating means, such as a magnetron, is controlled by two switching devices, which switching devices are controlled by the microcomputer.         When the user actuates a start switch, the first switching device is actuated by a control signal from the microcomputer, and thereafter, the second switching device is actuated to activate the power switch if the heating appliance is in proper operating condition.  The microcomputer stops the entire heating operation whenever the heating means is not operating properly, by sensing an improper condition of the second switching device.

Abstract: ABSTRACT:            In a differential amplifier with single-ended drive in accordance with the invention a balancing impedance is arranged between the base of the transistor connected to the signal input and the common point of the two emitters of the transistors which form a differ-ential pair. The capacitance value of the capacitor which forms at least part of the balancing impedance is at least substantially equal to the capacitance value of the stray capacitance of the collector-substrate (or "earth") junction of the transistor which forms the cur rent source. This results in a symmetry of the capaci-tances between the input and the common point and between the common point and earth via the transistor forming the current source, which yields an improved balance in the output signals on the output terminals and a flat fre-quency response of the differential amplifier for higher frequencies.
