20070245890 - Actuator with a non-contact position sensor: An actuator having a fixed part, a movable part movable with respect to the fixed part in a travelling direction, and a non-contact position sensor connected to the movable part to read the position of the movable part. The position sensor has a reading device connected to the fixed part... Agent: Charles N.j. Ruggiero Ohlandt, Greeley, Ruggiero & Perle, L.L.P.

20070245891 - One piece slipper holddown device: A holddown pin mechanism for hydraulic power units is a ball guide with a cylindrical flat base having a central opening, a plurality of spaced elongated holddown pins have one end rigidly secured to one side of said ball guide. The pins extend outwardly at right angles from the side... Agent: Zarley Law Firm P.L.C

20070245892 - Two-cycle, opposed-piston internal combustion engine: In a two-cycle, opposed-piston internal combustion engine, opposed pistons disposed in a cylinder are coupled to a pair of side-mounted crankshafts by connecting rods that are subject to substantially tensile forces acting between the pistons and the crankshafts. This geometry reduces or eliminates side forces between the pistons and the... Agent: Terrance A. Meador Incaplaw

20070245893 - Piston assembly for a food extruder: A piston assembly for a food extruder having a food reservoir with a chamber and an inner surface, a piston rod and a piston dish. The piston rod slidably extends into the chamber of the food reservoir. The piston dish is attached loosely to the piston rod and has a... Agent: Patenttm.us

20070234899 - Fluid powered dual-piston actuator with efficient fluid porting and method of implementation: In an actuator, a first piston is attached to a first toothed rack, and a second piston is attached to a second toothed rack. A rotary member is attached to one pinion mating with the first or second toothed racks. A first volume is disposed in the cavity on one... Agent: Oblon, Spivak, Mcclelland, Maier & Neustadt, P.C.

20070227348 - Hydraulic hand pump with locking device: A method and apparatus is provided that includes a hand pump having a handle locking mechanism, a counter bored nut, pivoting links, and unloading valve assembly.
