Abstract: A method of converting a thermometer code in an analog-to-digital converter to a binary code. The method involves counting the ones in the thermometer code and using the parity of the count as bit 0 of the binary code; downsampling the thermometer code by dropping every other bit to form a downsampled code; counting the ones in the downsampled code, and using the parity of that count as bit 1 of the binary code; and repeating the procedure until the binary code is completed. A circuit carrying out this method in a single clock cycle without computations is disclosed.

Abstract: An improvement in a rotary vee device that includes relative rotational and reciprocal motion between the interior walls of the cylinder and the exterior walls of the pistons characterized by each piston having first flow areas defined on its periphery and a first fluid flow passageway; each of the first fluid flow passageways in communication with the interior of its respective cylinder above its respective piston and with its respective first flow areas; and each cylinder wall having intake ports and discharge ports located at predetermined locations.

Abstract: An improved engine, particularly of the rotary type, or so-called angle piston type, having conventional components and characterized by a compressor serving as a supercharger interposed between the carburetor and the engine intake ports for compressing the combustible mixture; a bypass manifold for passing compressed combustible mixture to the suction side of the compressor; and a fine throttle means for controlling the proportion of combustible mixture bypassed for fine control and efficient combustion in the engine. The master throttle on the carburetor is employed only for major adjustments in power requirements. Also disclosed are details of critically located and designed intake ports and passageways and discharge ports and passageways to take advantage of centrifugal force of the angle piston type engine to obtain very nearly perfect scavenging, as well as details of employing a center section compressor for compressing the combustible mixture.
