Abstract: A one-piece, self-lubricating, thermoplastic sealing member suitable for a single action piston pump, the sealing member comprising a tubular shaped body, a peripheral portion of which is radially cut into two flanges of preselected length and thickness. One of the flanges has a shorter radial length and a thinner width than the other flange. The flanges are substantially in registry with one another and are bent, preferably in the vicinity of their respective bases, in the same direction to a preselected angle below 20.degree. relative to a transverse axis of the sealing member. When the sealing member is disposed in an annular space between the piston and the cylinder, the double flange portions of the sealing member are in contact with the annular surface of the cylinder or alternately, with a fixed or moveable shaft, providing two sealing engagements therebetween in seriatim, and the oppositely disposed peripheral portion of the sealing member is secured in the piston, or alternately, in the cylinder.

Abstract: A burner having a pulsating mode of operation has a combustion chamber for the periodic burning of successive separate charges of combustible fuel continuously supplied from an inlet system. Upstream of the combustion chamber is an ignition chamber having roughened internal walls, an ignition source and an inlet system for fuel and oxygen. During use of the burner, periodic ignition of successive separate charges of combustible gas in the ignition chamber produces fast moving combustion or detonation waves capable of igniting the successive separate charges of combustible fuel in the combustion chamber.

The printer comprises a CO.sub.2 gas laser light source, a modulator for the laser beam from said laser source, an optical scanning system for scanning the laser beam, which is passed through said modulator, transversely of a predetermined recording surface while focusing it on said surface, and a web feed mechanism for feeding a heat-sensitive recording web, which presents said recording surface, in a direction at right angles with the direction of said beam scanning.

Abstract: A control system is disclosed for an ion implantation system of the type in which the wafers to be implanted are mounted around the periphery of a disk which rotates and also moves in a radial direction relative to an ion beam to expose successive sections of each wafer to the radiation. The control system senses beam current which passes through one or more apertures in the disk and is collected by a Faraday cup. This current is integrated to obtain a measure of charge which is compared with a calculated value based upon the desired ion dosage and other parameters. The resultant controls the number of incremental steps the rotating disk moves radially to expose the adjacent sections of each wafer. This process is continued usually with two or more traverses until the entire surface of each wafer has been implanted with the proper ion dosage.

Abstract: Two embodiments of a non-compatible television system are disclosed. In the first embodiment, two video sources of color television picture information, comprising an independent or stereoscopic pair of real-time images, are encoded and transmitted over a standard bandwidth channel to a non-standard television receiver, i.e., one with means for decoding the encoded transmission. In the case of independent images the received encoded video signal is decoded to recover the two video sources for display; and in the case of stereoscopic images the received encoded video signal is decoded for presentation of stereoscopic imagery. In the second embodiment, a single video source of real-time color television picture information is encoded and transmitted over a half standard bandwidth channel to a non-standard television receiver. The received encoded video signal is decoded to recover the single video source for display.

Abstract: An optical system for an intruder detector which employs an infrared ray detecting element and a parabolic mirror above the infrared detecting element for collecting infrared rays from a detection region and directing them onto the infrared ray detecting element, and which has a detecting range through a wide visual field of 360.degree.. Reflecting mirrors 3 having the visual field of 360.degree. are disposed around the outside of a parabolic mirror and confront the parabolic mirror 1 around the outer periphery of the infrared ray detecting element 2. A window 5 which transmits infrared rays and does not shield the visual field of the mirror 3 mounts the parabolic mirror 1 at a prescribed position with respect to a base 6. A convex lens 15 located at the conical axis of the parabolic mirror 1 forms another detection region directly under the intruder detecting device. The intruder detector using this optical system is mainly for mounting on the ceiling of a house.

Abstract: A torque joint for transmission of force in both longitudinal and circumferential direction about thin-wall tubular torque tubes is provided by overlapping an inner one of said tubes and an outer one of said tubes, inserting a mandrel having longitudinal and circumferential slots therein, applying a deformation force for pressing the tubular members into the slots of the mandrels, and extracting at least a portion of the mandrel to provide the torque joint.
