Abstract: A B S T R A C T     A synchronous self-shifting toothed clutch, for use between a gas turbine and an electrical generator, of the type comprising an intermediate member  which moves helically relative to a rotary clutch part in the direction to interengage the coacting clutch teeth upon passage of the rotary clutch parts through synchronism in one direction of relative rotation, and wherein a dashpot is provided for cushioning the final phase of clutch engagement.         The improvement comprises a first ring of locking dogs carried by the said rotary clutch part, and a second ring of locking  dogs carried by a control sleeve mounted for axial movement relative to the intermediate member.   The dogs of the first ring are alternately  short and long, the short dogs being narrower than the long dogs, and the dogs of the second ring are alternately short and long, the short dogs being wider than the long dogs.   In each ring, the long dogs project axially beyond the short dogs towards the other ring, and the spaces between the dogs are alternately wide and narrow.       With the clutch teeth partially engaged the long dogs of each ring can interengage with the long dogs of the other  ring, but the short dogs of the second ring are baulked axially by the long dogs of the first ring.  With the clutch teeth fully interengaged the dogs of each ring can interengage with the dogs of the other ring.

Abstract: SYSTEM FOR CONTROL OF EXHAUST GAS RECIRCULATION            ABSTRACT    In an automotive internal combustion engine, metered quantities of exhaust gases are recirculated by way of a control value to the intake manifold of the engine in order to control temperatures within the combustion chambers, thereby reducing formation of oxides or nitrogen.  The control or metering valve is actuated by a vacuum motor which may be in the form of a diaphragm and which vacuum motor is actuated by vacuum signals derived from a pair of ports in the carburetor which supplies the air-fuel mixture to the engine.  Vacuum signals are picked up at each of the two ports in the carburetor and merged by way of a single conduit to the vacuum motor chamber of the control valve. Location of the ports and calibrated restrictions within the conduits regulate the control of the metering valve.

Abstract: ELECTRONIC COMPOSITE PHOTOGRAPHY WITH              COLOR CONTROL                  Abstract of the Disclosure Improved electronic compositing procedures and apparatus are described, based typically on the blue screen process and suitable for processing motion pictures of professional quality and the like.  The electronic system produces a com-posite color picture from foreground and background video signals.  The foreground signals represent respective color components of a foreground scene having areas of different effective transparency against a backing effectively illuminated with light which is predominantly confined to one of the colors, e.g. blue, and which contains an impurity of at least one other color.  The improvement comprises sub-stantially compensating for this color impurity throughout a continuous range of the effective transparencies of the foreground scene.  The result is improvement in performance of the system in relation to color accuracy.

Abstract: ABSTRACT             A machine tool having a tool-supporting hollow spindle has the tool mounted in fixed relation to a draw bar which slides axially within the spindle between a tool remaining position and a tool release position. A barrel cam within the spindle is adapted to be engaged and rotated by a cam driver member secured to an actuating shaft longitudinally movable within the spindle. The spindle rotates with the cam until a predetermined angular position is reached, after which additional longitudinal movement of the actuating shaft causes movement of the draw bar downwardly within the spindle from its tool retaining position to its tool release position, where the tool is resiliently supported until it is removed, either manually or by automatic means.

Abstract: ABSTRACT OF THE DISCLOSURE         A multiple-stage catalytic conversion system in which a hydrocarbonaceous charge stock and hydrogen flow serially through a plurality of catalytic reaction zones in each of which the catalyst particles are movable via gravity-flow.  The reaction product effluent from each zone, in admixture with added hydrogen is heated prior to the in-troduction thereof into the succeeding reaction zone.  The disclosed technique alleviates problems associated with the occurrence of stagnant catalyst areas as a result of cat-alyst particles being "pinned" within the reaction zone and thus unable to assume a downward gravity-flow pattern.          In addition, the technique allows utilization of excess heater capacities before and between reaction zones.

Abstract: Abstract Of The Disclosure A hydrometallurgical process for recycling the paste and electrolyte of junk lead-acid batteries begins by separating the paste and electrolyte from the junk batteries. The paste and electrolyte are then reacted to increase the lead sulfate content of the paste and reduce the acid content of the electrolyte.  Sulfuric acid may be added to the mixture of paste and electrolyte if there is an insufficient amount of electrolyte to react with all the paste. Excess liquid is then remove from the mixture of paste and electrolyte, after which the paste is mixed with an aqueous ammoniacal ammonium sulfate solution to dissolve a substantial portion of the lead sulfate from the paste.  The remaining solid materials are then separated from the resulting pregnant lead solution, after which lead carbonate is precipitated from the pregnant lead solution by the addition of ammomium carbonate, ammomium bicarbonate or carbon dioxide.  The precipitated lead carbonate is removed from the spent liquid and either converted to lead oxide by calcining, or mixed with sulfuric acid and then calcined or reacted with a chemical reducing agent to convert lead dioxide therein to lead oxide, and the lead oxide-containing material is then mixed with sulfuric acid in a second sulfating reaction to increase the lead sulfate content thereof. The resulting product is mixed with an aqueous ammoniacal ammonium sulfate solution to dissolve further lead sulfate therefrom. The resulting pregnant lead solution is separated from any solid materials remaining therein, after which lead carbonate is precipitated from the solution.  If desired, the original battery paste may be calcined or reacted with a chemical reducing agent before it is reaction with the battery electrolyte in the primary sulfating reaction, and in this case the secondary recovery process may be omitted.
