Abstract: A float system for a ball type accumulator includes a circular hollow float member which surrounds the float travel guide rod in the ball type accumulator. Connecting the float member to the vertical guide rod is a ball member which is located in the center of the float. A circular arcuate band surrounds the ball member thus allowing the float to tilt with respect to the vertical guide rod as the level of the fluid tilts within the accumulator. The tilting of the float prevents the float from flooding when the ball type accumulator is moved.

Abstract: In reversible compressed air rotary motors for compressed air tools, particularly for wrenches, it is known to discharge the waste air radially from the casing of the motor, which results in a considerable nuisance, in particular as regards noise. Furthermore, due to the close positioning of the compressed air inlet and air outlet, poor efficiency is achieved. To avoid those drawbacks in a rotary sliding vane motor having an elliptical working chamber, the rotor end over on the inlet side is rotatably mounted, and air outlet means is arranged axially and lies in both the clockwise as well as in the antic-clockwise direction or rotation of the rotor relative to the major semi-axis of the elliptical working chamber. Thus by rotating the end cover to one or other of its limit positions, the outlet means communicate with different pairs of passageways.

Abstract: A spring for a top entry ball valve includes a generally "u" shaped spring body with an open end. The ball valve includes a valve body with inlet and outlet flow passages communicating with a valve chamber. A ball element is mounted in the valve chamber for rotation between open and closed positions relative to the flow passages. A seal element is mounted adjacent each flow passage with a sealing face in opposed sealing relation to the ball element. A moveable seat assembly is located between the seal element and the valve body for maintaining the seal element in sealing relation to the ball element. The spring is located between the moveable seat assembly and the valve body and is adapted to urge the moveable seat assembly and the seal element toward the ball element.

Abstract: An electrical entry is provided to secure an armored electrical cable to an access port of an electrical enclosure. The cable entry has a body portion for securing to the enclosure, with a passage therethrough to receive the armored cable, and a plurality of chuck members each internally profiled to engage the corrugations of the metal armor. The outer surface portions of the chuck members are tapered to engage a radially inner tapered portion of the entry body, and a compression nut axially compresses the chuck members within the entry body into gripping relation with the cable armor to mechanically secure and electrically ground it; a seal is provided within the entry to prevent passage of moisture or liquid through the entry.

Abstract: A method and apparatus for detecting proper arrangements of fuses (10) in fuseblock (70). A scanner (80) detects a chemical material in fuse (10) and identifies the material and correlates the material to a proper amperage rating. The arrangements of different amperage rating fuses in the block is automatically compared to a standard by a microprocessor or computer to determine if fuse location is proper.
