Abstract: ABSTRACT OF THE DISCLOSURE     An upstream or predeposition cathode system for use with glow discharge deposition apparatus, said apparatus adapted for the continuous production of large area -photovoltaic devices.  In such apparatus, process gases are commonly introduced into a deposition chamber from a gas manifold disposed upstream of a substrate.  As the process gases are drawn across the surface of the substrate, they are disassociated and recombined under the influence of an electromagnetic field developed by a deposition cathode or microwave generator.  By providing a precathode system upstream of the deposition cathode or microwave generator, (1) impurities in the process gases, (2) contaminants from the walls of the deposition chamber and (3) initially disassociated and recombined process gas compositions may be deposited onto and collected from a collection plate disposed upstream of the substrate.  In this manner, the process gases subjected to the upstream electromagnetic field are more easily broken down by the deposition cathode and deposited onto the substrate in desired chemical combinations and compositions so as to provide improved electrical, chemical and optical properties.  Also disclosed herein is the use of such a precathode assembly to aid in the high speed deposition of homogeneous, amorphous, powder-free semiconductor material of uniform thickness across the entire width of the substrate.

Abstract: LABEL PRINTING AND APPLYING APPARATUS                     Abstract of the Disclosure A hand-held label printing and applying apparatus includes a platen  and a movable printer for successively printing pressure sensitive labels advanced across the platen  by a carrier web.  Each label is separated from the web by pulling the web around a delaminator with a web engaging feed wheel rotatably indexed in response to release of a finger actuator.  When the apparatus is assembled for printing relatively short labels, each separated label engages applicator rollers rotatably supported by a pair of non-rotating adaptor hub members.  The hub members have aligned eccentric holes for receiving a support shaft which is used without the hub members for supporting larger applicator rollers when the apparatus is assembled for printing longer labels.  The carrier web is directed into engagement with the feed wheel by a form roller supported for rotation by a U-shaped adaptor which is used when the apparatus is assembled for printing shorter labels.  The U-shaped adaptor is omitted when the apparatus is assembled for printing longer labels, and a larger feed wheel is assembled.

Abstract: Improved Siren Abstract A siren comprises a compressed air supply which is deflected by stationary deflectors to exit radially through stator ports.  A rotor with spaced ports rotates between the stator and deflector thereby opening and closing the stator ports.  Stationary vanes are disposed at circumferentially spaced locations, and constitute together with the deflector plate and stator and rotor housing, plenums.  There are fewer rotor ports than stator ports, which generates an out-of-phase acoustical pattern which creates an acoustic combination from the stator ports of an acoustic output at a distance from the siren which is more uniform spatially. The thermoplastic seal between the stator and the rotor has minimal clear-ance under operating conditions having been run-in and plastically deformed at a temperature higher than for normal operation.

Abstract: ABSTRACT OF THE DISCLOSURE          In a cyclic hydrogen sulfide oxidation-catalyst regeneration process using an aqueous chelated polyvalent metal catalyst solution, excessive degradation of the aminopolycarboxylic acid chelating agent is prevented by incorporating in the solution an effective amount of a stabilizing agent capable of retarding or preventing rupture of nitrogen-carbon bonds in the chelating agent during oxidative regeneration of the catalyst solution.          Alkaline thiosulfates are the preferred stabilizing agents.          Particularly good results are obtained using an alkaline thiosulfate stabilizer in a catalyst solution comprising the dimer form of the NTA-iron complex.

Abstract: ABSTRACT OF THE DISCLOSURE         A vibration isolating and damping suspension strut for vehicle undercarriages comprising an elongated cylinder and piston structure wherein the cylinder is divided into opposed chambers which are in communication with each other by passages formed in the piston and in a flow restricting shuttle valve mounted on the piston rod.    When the strut undergoes a retraction stroke of the piston to absorb loads silicone fluid is compressed in the opposed chambers and transferred from the chamber opposite the piston rod to the rod side chamber through passages in the piston only. When the strut rebounds or extends its piston rod fluid is forced to flow through passages in the shuttle valve member and the piston flow passages at a more restricted rate. The piston flow passages and the shuttle valve are arranged to direct fluid flow toward the outer cylinder borewall to improve heat transfer to the exterior of the strut and minimize heating of the fluid contained in the cylinder chambers. Alternate embodiments of the suspension strut have spiral fluid transfer grooves formed on the periphery of the piston or on a cylinder sleeve insert member.
