Abstract: A B S T R A C T   An implantable electrically operated medical device, such as a pacemaker, having one or more electrochemical cells and operative electric circuity mounted in an encapsulated covering of epoxy resin which is imper-meable to body fluids.  The electrochemical cells generate a hydrogen gas and the encapsulated covering, while being relatively impermeable to hydrogen gas is capable of passing the gas through at a relatively low permeation rate.- Buildup in pressures within the encapsulant occur under increased hydrogen evolution rates from the electrochemical cells and the improved device modifies the shape of the electrochemical cells and reinforces the epoxy resin encapsulant over the corners of the cells to strengthen the en-capsulant covering and increase the burst strength of the device.

Abstract: A B S T R A C T     Apparatus for automatically coupling pneumatic brake lines on railway wagons and other articulated vehicles.  The apparatus comprises an axially and resiliently compressible tubular projection which is fitted to the end of the vehicle to extend outwardly beyond the coupling plane of the vehicle.  The head at the free end of the projection is formed to align and connect airtightly with a similarly formed head at the free end of a like formation on an adjacent vehicle when the draw-gear of the vehicles is coupled.  This action compresses each projection thereby opening a valve between the bore of the projection and the brake line of its associated vehicle.  The valve is releasably locked in the open position so that if the vehicles are uncoupled deliberately or accidentally air in the brake line will be dissipated thus applying the brakes of the vehicle.

Title: FAN BEAM X- OR .gamma.-RAY 3-D TOMOGRAPHY

Granted: 1980-11-25
Abstract: Application for Patent of Douglas P. Boyd and Michael C. Goitein for ABSTRACT OF THE DISCLOSURE     A fan-shaped beam of penetrating radiation, such as X-ray or .gamma.-ray radiation, is directed through a slice of the body to be analyzed to a position sensitive detector for deriving a shadowgraph of transmission or absorption of the penetrating radiation by the body.  A number of shadowgraphs are obtained for different angles of rotation of the fan-shaped beam relative to the center of the slice being analyzed.  The detected fan beam shadowgraph data is reordered into shadowgraph data corresponding to sets of parallel paths of radiation through the body.  The reordered parallel path shadowgraph data is then  convoluted in accordance with a 3-D reconstruction method by convolution in a computer to derive a 3-D reconstructed tomograph of the body under analysis.  In a preferred embodiment, the position sensitive detector comprises a multiwire detector wherein the wires are arrayed parallel to the direction of the divergent penetrating rays to be detected.  A focused grid collimator is interposed between the body and the position sensitive detector for collimating the penetrating rays to be detected.  The source of penetrating radiation is preferably a monochromatic source.

Title: Insulated door mounting frame structure
Inventor: HEANEY JAMES J
IPC: A47F3/04
Filed: 1975-12-18
Granted: 1979-05-01
Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to commercial upright type refrigerators.  Generally, the frame structure and the door frames are made of metal because of the durability and appearance of that material and the ease with which it may be manufactured.  Most metals, however, are superior conductors of heat.  It has become the practice to provide a submerged electrical heating wire located within the door mounting frame structure which, when supplied with electrical current generates a small amount of heat, ade-quate to prevent condensation.  The heater wires do not consume a large amount of energy relative to the total energy consumed by most refrigerators, nevertheless it is desirable to conserve energy by providing a door frame mounting structure which is thermally as efficient as possible.  The present invention utilizes a thermal barrier between the cold portion and the warm portion of the frame in combination with a divided thermal conduction path extending from an intermediate portion into the cold por-tion.  The divided path comprises a thick load-bearing section through which conduction is impeded by the thermal barrier, in parallel with a thinner sealing face plate section exposed to the air outside the refrigerator and electrically heated to prevent condensation.  In this way condensation is prevented and the heat load on the refrig-erator is minimized.

Abstract: ABSTRACT            An improved process for dyeing nylon carpeting material which is tufted or woven from a blend of cationic dyeable nylon yarns and acid dyeable nylon yarns is provided.  Staining of the cationic dyeable portion is substantially eliminated and red and dull shades on the deep dyeing acid dyeable nylon is avoided by using as the acid dye a member of a small class of monoazo dyes made by coupling an appropriate diazotized aminobenzene sulfonic acid into N-ethyl-N-phenylbenzylamine.  The monoazo dyes of the invention are applied to the carpet material along with an appro-priate cationic dye in a conventional application procedure.  The use of the monoazo dyes according to the invention produces a dyed blended nylon carpet material in which the cationic dyeable port-ion is not appreciably dyed or stained by the acid dye and in which the acid dyeable portion is characteriezed by outstanding light fastness and excellent transfer properties.  Deep dyeing acid dyeable nylon is dyed a bright crisp shade with the monoazo dyes according to the invention.

Abstract: ABSTRACT OF THE DISCLOSURE    Extending the size of the main memory of a data processing system having a synchronous inner storage unit by attaching a relocation translator having special connection interfaces and translated addressing for attaching a synchro-nous outer storage unit and an asynchronous storage unit which may be remotely located from the processor.  A different form of storage cycle is generated by the transla-tor for interfacing each of the three storage units being accessed.  The translator performs address translation which expands the number of bits in the physical address to support the extended main memory.  The extended address uses a concatenation of a program-derived address and a machine-derived address key.    The maximum extendable size of the memory can substan-tially exceed the maximum addressing capability of any program, which is determined by the relocatable addressability obtained through any stack of segmentation registers.  The maximum extendable size of the main memory is determined by the number of bit positions in the physical block address field in a segmentation register (for addressing a physical block in any of the storage units) concatenated with the number of bit positions needed to address a location in any selected storage block.
