Abstract: ABSTRACT:              The invention relates to a glow-discharge starter having a bimetallic electrode and a rare gas.  According to the invention the glow-discharge starter also comprises a reversible getter which, when the temperature increases, gives off a gas and, when the temperature decreases, absorbs the gas and the value of the gas pressure also determines the electric conductivity of the glow-discharge starter. In this way a glow-discharge starter is obtained in which undesired breakdown can be prevented by controlling the gettering temperature.

Abstract: LINE ENDER                 Abstract of the Disclosure A line ender for use in coupling an end choker line to a hauling line in a log-hauling system.  The ender is formed of a unitary body having an elongate, axially extending chamber which terminates at upper and lower seats for nubbins located at the ends of the hauling and choker lines, respectively.  The two lines are received through bores in associated ends in the body.          An opening on one side of the ender body is dimensioned to allow the main line nubbin to move therethrough into its seat. An opening on the other side of the body is longitudinally aligned with the lower portion of the first-mentioned opening, allowing a choker nubbin to be passed transversely through the body with the hauling line nubbin in its seat. An entry slot on the lower portion of the body extends from one of the openings to the lower bore in the body in a path which revolves about a quarter of the circumference of the body, providing entry of the choker line into the bore at the lower end of the body.

Abstract: ABSTRACT           This invention covers fibrillated matrix active layers for gas-fed electrodes having improved strength, service durability and resistance to mechanical failure as well as methods of making such active layers and electrodes.  The term "matrix" is used to indicate that the active carbon particles (which constitute the main component thereof) are disposed within an unsintered network of carbon black/PTFE (fibrillated) material.  The finished electrodes are generally three-layer laminates wherein said active layer is positioned between a hydrophobic (wet-proofing) backing layer on its non-working surface and a current distributor on its working surface.  Key features of technical advancement in this invention include the use of active carbons as the main electrocatalytic component of the active layers disposed within a strong, highly conductive matrix, the use of a shear blending step to mix the ingredients and fibrillate said matrix and the final formation of the complete mixture into an active layer without sintering.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is an integrated flow control valve and check valve arrangement for gases, and in particular an arrangement having a check piston incorporated into the outlet side of a gas valve.  By incorporating the check piston in the outlet of the gas valve itself, the check piston protects the gas valve as well as the gas service against possible back flow of fluid, for example, water.  For example, if the gas valve is connected by a hose to a water faucet, water cannot flow back through the gas valve and into the gas line which typically has a much lower supply pressure, e.g. 1/2 PSI, than the water supply (20 to over 100 PSI).  The invention thus frustrates vandals who have been known to connect a rubber hose between a gas cock and a water faucet and then turned both items to the open position.

Abstract: A STEERING SYSTEM AND COMPENSATING VALVE                   Abstract of the Disclosure A hydrostatic power steering control system with variable feedback compensation employing a unique compensating valve.          The steering control system includes first and second hydraulic cylinders, each having two internal chambers denoted as head and feedback chambers.  A piston is movably retained in each of the cylinders and is attached to a piston rod which extends outwards.  The pair of piston rods are connected to a pair of steerable wheels by a mechanical linkage.  Fluid contained in a reservoir is pressurized by a supply pump and is selectively passed to a head chamber of one of the cylinders by a control valve.  The control valve is actuated by pressure differences in two interconnected fluid passages which connect to the feedback chambers of the two cylinders.  A pressure difference in these passages is created by manually operating a steering wheel which actuates a metering pump positioned across the fluid passages.          In order to alleviate pressure fluctuations between the two feedback chambers, a compensating valve and a pair of one way check valves are connected across the fluid passages in a parallel relationship.  The compensating valve allows pressurized fluid above a predetermined pressure range value to be relieved from the system, but does not limit a pressure value generated by the metering pump.

Abstract: ABSTRACT OF THE DISCLOSURE         A wideband chroma key switching signal is generated from lower bandwidth chrominance signals in a video signal by first conventionally generating a chroma key switching signal from these chrominance signals, and then detecting high frequency transition components in the corresponding luminance signal.  These luminance signal high frequency components are then added to the switching signal in a manner that insures that their polarities match, thereby generating a higher bandwidth chroma  key switching signal.  This resultant higher bandwidth chroma key switching signal is used to control cross fade amplifiers which function to output either the video signals of a first or a second scene with linear transitions between these video signals during switching.

Abstract: ABSTRACT       The present invention is directed to a blend comprising a normally-solid polyestercarbonate copolymer or terpolymer and a normally-solid aromatic hydrocarbylene polycarbonate resin, the polyestercarbonate copolymer or terpolymer containing a plurality of repeating units corresponding to the Formula I:                                  I   wherein each R is independently aromatic hydrocarbylene or inertly-substituted aromatic hydrocarbylene, each R' is independently meta- or para-phenylene and X is a number from 0.05 to 10.  The invention is characterized in that the polyestercarbonate copolymer or terpolymer comprises from 10 to 26 weight percent of the blend, the polycarbonate resin comprises from 90 to 74 weight percent of the blend, and the mole percent ester in the blend ranges from 10 to 22 based upon the sum of the number of moles of ester and carbonate groups.  The blends of this invention exhibit mechanical and thermal properties very similar to a synthesized 29,368-F     polyestercarbonate copolymer or terpolymer having the same overall ratio of ester to carbonate groups. Surprisingly, these blends exhibit toughness superior to that of any of the component polymers at temperatures below -25°C and improved Izod impact strength over a wide range of temperatures where the notch has a 5 mil (0.13 mm) radius.  These blends are used in applications where a tough rigid thermoplastic is required.

Abstract: ABSTRACT OF THE DISCLOSURE A novel sliding-vane type oil free rotary compressor is provided herein.  Such compressor includes a center housing, two side housings, a rotary sleeve rotatably mounted in the center housing, a rotor eccentri-cally contained in the rotary sleeve, a plurality of vanes movably fitted in the rotor, a discharge chamber provided in the side housing, a pressure chamber defined by and between the rotary sleeve and the center housing and connected to the discharge chamber through at least a high-pressure passage, the high-pressure passage being disposed in the center housing and communicating with a passage extending to and along the side surface of the center housing, through the side housing and communicating with the dis-charge chamber, the high-pressure passage opening to the pressure chamber through at least one throttle means, whereby the rotary sleeve is floatingly supported by at least one of the static pressure of said pressure chamber and the dynamic pressure of fluid flowing through the throttle means from the high-pressure passage to the pressure chamber.  Such compressor can support the rotary sleeve at a wide range of rotary speeds by the use of static and dynamic pressures of a compressible fluid, as compared with the conventional compressor using incompressible fluid to support the rotary sleeve.  The com-pressor has a relatively small heat generated from sliding friction, because the rotary sleeve slides relative to either of the vane and the center housing so as to have a smaller resistant force.  Therefore, it is particularly suit-able for a supercharger required to operate at high compression ratios and large capacities for use in an automobile.
