To serve a turret-mounted tank cannon, automated loading apparatus includes a pair of arcuate guide tracks vertically mounted to the turret. The guide tracks, lying on radii centered with the cannon elevating axis, guide a trolley for movement between magazine and cannon loading postions. A rammer, carried by the trolley, is activated to retrieve an ammunition round from magazine storage and to ram the round into the cannon breech regardless of cannon position in elevation and azimuth. The troll...

An analog line store comprises a bank of storage capacitors n in number, an n:1 read multiplexer for sequentially sampling from the n storage capacitors as part of a read-then-write operation, a 1:n write multiplexer for sequentially sampling to the n storage capacitors as a further part of the read-then-write operation, and a scanning register for generating control signals for the write multiplexer and the read multiplexer. The storage capacitors have similar capacitances that are substantiall...

In an ammunition fuzing system, a fuze setter is inductively coupled with an electronic fuze incorporated in the projectile of an ammunition round being fed to a rapid-fire cannon to transmit power supply charging energy and fuze-setting data thereto. A detonation counter is incremented at a high counting rate to accumulate a projectile flight time count indicative of the fuze-setting data. A conformation signal is transmitted to the fuze setter for determination that the flight time count accep...

A process for the conversion of olefinic hydrocarbons according to the olefin reaction including olefin disproportionation by contacting the olefinic hydrocarbon with a catalyst comprising a compound of vanadium or niobium complexed with NO and a selected complexing agent (e.g., benzoic acid) and combined with an organoaluminum compound (e.g., methylaluminum sesqui-chloride). The metal complexes which form a part of the catalysts are also claimed. 10 Claims, No Drawings

Melt-spinnable thermoplastic polymeric filaments are melt extruded from at least one spinneret die plate having at least 25 spinning orifices per square inch of effective spinning area through an airgap of less than 1 inch into a liquid quench medium, for example, water. The surface tension of the quench liquid is maintained at least below 65 dynes per centimeter. The as-spun filaments can have a denier per filament in the range of about 4 to about 600. Polypropylene filaments processed in this ...

A process for the conversion of olefinic hydrocarbons according to the olefin reaction (e.g., the olefin disproportionation reaction) by contacting the olefinic hydrocarbon with a catalyst comprising a coordination compound of molybdenum or tungsten complexed with NO, together with an organoaluminum adjuvant. 15 Claims, No Drawings

A novel oil recovery vessel for removing oil and other floating impurities from the water surface, is provided with means for collecting such impurities, means for conveying said collected liquid impurities through the vessel and means for the discharge of redundant water from the vessel the conveying means keeping the emulsification of the removed impurities to a minimum despite a rather high operational throughput.

A compressed-air braking and brakes locking system for trailers is provided, which permits to release the trailer brakes and to apply and lock the trailer brakes again when the trailer is separated from its tractor. The system includes a compressed air reservoir and an emergency relay valve on the trailer and a hand operated valve so arranged to put the control inlets of the emergency relay valve and of the brake unlocking device selectively in communication with the control circuits of the trac...

Articles are printed or decorated with thermoplastic color by an offset process, by melting the thermoplastic color in a screen, applying the melted thermoplastic color by the screen to a transfer member which is at a temperature below the melting temperature of the thermoplastic color, adhesively coating the surface of the article to be printed or decorated, and then transferring the color from the transfer member to the adhesively coated article surface.

Molten metal is treated by flowing gas through it. The container for the treatment is provided with a fore hearth, with a cover and with means for blowing the gas in fine bubbles into the metal. From the container the treated metal flows into a hopper provided with a cover having means for flushing the hopper with an inert gas.
