Abstract: A fired rifle cartridge is resized in the cartridge neck area for reuse. A first die set is employed to compress the cartridge neck such that the inner surface of the neck fits a standard size bullet. A second die set is used to expand selected areas of the cartridge neck to snugly fit the firing chamber. The resultant ammunition round can be fired with a greater degree of accuracy than ammunition resized by prior art procedures, because the longitudinal axis of the cartridge neck coincides with the bore axis of the firearm.

Abstract: A filtration apparatus designed to remove solid contaminants from a liquid includes an endless filtration belt located in a liquid tank, so that liquid flows through minute openings in the belt into a liquid collection box located within the belt envelope. Edge areas of the belt are engaged with annular support walls carried by the tank side walls, such that a continuous seal is provided against migration of contaminants around the belt side edges. Contaminants collecting on the belt surface can be periodically removed by moving the belt across a spray system that dislodges the contaminants from the belt into the tank. A drag conveyor removes contaminants from the tank.

Abstract: A high speed shuttle conveyor includes two motor-driven belts for moving two carriages forwardly to rapidly propel an article conveyor from a starting position to an ending position. The belt movements are reversed to return the carriages to the starting position. Each carriage has a retractable pusher element for imparting forward movement to the article conveyor, and a retractable retention element for preventing the article conveyor from moving forwardly at a faster speed than the pusher element. When each carriage reaches the limit of its forward stroke the retention elements exert snubber actions on the carrier; the carrier is safely decelerated to a motionless condition and released.

In the position that the louver is open, air can flow through the screen past the air conditioner unit.

Abstract: A golf putter includes a putter head that is equipped with three ball-striking surfaces, such that the putter can be used by a right-handed golfer or a left-handed golfer, employing either a conventional putting stance perpendicular to the ball roll path or a non-conventional putting stance facing the ball target. The club head is connected to the shaft at a center location coinciding with the head center of gravity. Also, the upper surface of the putter has a central cavity and two opposing rails that cause the putter weight to be concentrated at the perimeter of the head, thus tending to minimize the effect of mishits on ball travel accuracy on all three ball striking positions. The shaft to head connection is aligned with the ball roll in all ball striking positions.

Abstract: A pneumatic pressure tank and valve system for pneumatically conveying a granular material to a destination can include a pressurizable chamber adapted to be filled with granular material through an upper inlet opening. When the chamber is filled, pressurized air is introduced into the chamber to lift a floating cone valve to a position closing the inlet opening. Pressurized air in the chamber conveys the granular material through an outlet opening toward the materials destination. The system operates on a very simple time cycle, while achieving effective use of the pressurized air for granular transport purposes.
