Abstract: S P E C I F I C A T I O N     Title of the Invention:        CARTRIDGE/CARRIER LOCKING DEVICE FOR      AUTOMATIC GUN   Abstract of the Disclosure:        A cartridge carrier locking device for an automatic gun including a latch plate pivotally mounted on an inner wall of a receiver to pivot in a seesaw like manner to have two ends thereof alternately protrude inside of the receiver.          The front end protrudes to restrain a cartridge and the rear end to restrain a carrier.  A spring pushes the rear end toward the inside of the receiver.  Against this spring, a breechblock and a cartridge brought out of a magazine respectively restrict the protruding motion of the rear end until the breechblock moves backward approximately to a maximum extent. The position at which the breechblock comes to restrict the protruding motion of the rear end of the latch plate is arranged to differ from the position at which the cartridge comes to restrict in such a way as to allow the rear end to lock the carrier.

Abstract: CONTINUOUS PAPER SORTING MACHINE                 Abstract of Disclosure Continuous paper sorter mechanism in which a receiver section is comprised of at least two columns of inclined side-by-side stacks of paper storage bins or shelves with entrances for receiving paper sheets from the feeder.    The receiver is mounted for lateral movement relative to a feeder mechanism, such that the bin entrances move past the feeder in ? generally vertical plane.  The feeder has an in-feed conveyor which takes paper from a copy making device such as a press or duplicating machine and feeds the sheets of paper either to an intermediate down-wardly inclined conveyor or onto an intermediate upwardly inclined conveyor, depending on whether the feeder is distributing paper sheets from the top or from the bottom.          Sheets from the intermediate conveyors in turn are trans-ported to a generally vertically disposed, reversible feeder conveyor.  The feeder conveyor is provided with a plurality of two-way deflectors which intercept the paper sheets and direct them off the conveyor moving either downwardly or upwardly.  A deflector guide section is disposed between the deflectors and the entrances of the bins in the receiver.  A proof tray mechanism is also provided over the in-feed conveyor.

Abstract: PNEUMATIC RODDING OF CONDUIT USING EVERTED FLEXIBLE TUBING Abstract of the Disclosure: Utility lines or cables are installed in under ground conduit using imperforate flexible tubing having a circumference no less than that of the conduit interior. One end of the tubing is everted and fixed within the conduit near end. Air blown into said near end is directed against a displaceable pocket between the fixed everted end and entering portion of the tubing so that the tubing lines the conduit interior wall, taking its shape and strength therefrom, as it is advanced through the conduit to the far end thereof. In one embodiment, the tubing when half way through is severed outside the conduit near end and a pull line attached thereto is drawn with the tubing the rest of the way through the conduit to its far end; and the tubing is twisted on the pull line to form a tow of higher tensile strength. In a modification, the twisting step is omitted and the pull line is attached to the inner portion of the tubing at the far end of the conduit; and it is drawn with the inner portion of the tubing back through the everted portion while continuing to blow air of reduced pressure into the near end of the conduit to prevent tubing collapse.

Abstract: METHOD AND APPARATUS FOR CONDITIONING     ABSTRACT   In order to reduce the electrical resistance of entrained fine particles of fly ash resulting from the burning of low sulfur coal and to enhance the efficiency of their collection by an electrical precipitator means, there is a conditioning of the particles carried in the flue gas stream by having a vapor of H2SO4 condensed and adsorbed on the particles themselves.  Sulfuric acid at ambient temperature is mixed with air in an acoustic nozzle to form a mist having an average particle size of about 10 microns which is injected uniformly into a cyclonically flowing stream of hot gas in a chamber located adjacent an upstream inlet duct portion of the precipitator unit.  The hot gas in the chamber vaporizes the acid which is then injected into the precipitator inlet duct so that the acid can condense on the particles.  The hot gas is preferably obtained from the combustion air preheater.

Abstract: Abstract of the Disclosure In a portable traffic control system in which receivers are controlled from a central transmitter the carrier signal employed is modulated by two different modulation signals in order to command a green light to be shown, reducing the possibility of this happening accidentally.  The receipt of a carrier signal with only a single pilot modulation causes production of a red signal.  An amber caution light if present is lit automatically upon turning off green, and flashing amber is produced by switching on green and then turning it off before the green can be lit.  A drop in battery voltage below a predetermined level will cause a flashing red signal to warn and conserve the battery power.  A non-resettable link in circuit with the green light is broken upon existence of a malfunction condition whereby another light is lit while green is alight, so that the green can no longer be lit until the unit is serviced to remove the malfunction.

Abstract: Abstract of the Disclosure: The electrolysis of aqueous alkali metal chloride solutions under pressure has already been carried out. In accordance with the invention there is applied a pressure of at least 8 bars in the anode apace for such an electro-lysis, as well as a special process for the work-up of the products of the anode space. The mixture of gas and ano-into leaving the anode space is at first mechanically se-parated, and the anolyte is then depressurized into a stripping column. In the course of this process a dechlo-rination and cooling of the anolyte are taking place. The anolyte is to enter the pressure release vessel (stripping column) with a temperature being above the boiling point of the anolyte at atmospheric pressure. The reduced pressure in to be between 2 bars and atmospheric pressure. By means or these measures it may be ensured that the anolyte in the stripping column reaches boiling point. Finally the chlo-rine set free in the pressure release operation is separat-ed from the anolyte.

Abstract: ABSTRACT      A soft permeable material, such as a foamed plastics material  or  a  fibrous  material  (10)  is  shaped,  and optionally provided with one or more facing layers (12), by applying to the faces thereof a polyurethane based prepolymer composition (11) under such conditions that a non-tacky coating having latent adhesive properties is formed.  The coated material (20, 40) may be stored for a period of several months and subsequently shaped by the application of heat and pressure sufficient to cure the pre-polyer.   Facing layers (13) can be bonded thereto simultaneously  without  the  application  of  additional adhesive substance.  The latent adhesive substance may be applied to the permeable material in solution or in the form of a dry film.  In the latter case the film may be applied initially to a facing layer.  The latent adhesive substance may be used to form reclaimed waste material into a coherent mass which can subsequently be shaped and faced  without  the  application  of  further  adhesive substance.
