A hydraulic motor receives pressurized fluid from a source controlled by a human operator to convert the energy in the hydraulic fluid to a rotational output to propel a drive wheel of a machine. The hydraulic motor includes an end cover, a manifold, a drive assembly, a wear plate, a housing, and an output assembly. The drive assembly includes a rotor with external teeth and a stator with internal teeth formed by rollers having end faces. The pressurized fluid from the source flows through the manifold to the drive assembly and causes rotational and orbital movement of the rotor relative to the stator. The rotational movement of the rotor is transmitted to the drive wheel by the output assembly. A first set of anti-cogging passages and a second set of anti-cogging passages communicate fluid pressure to the end faces in timed relationship to reduce cogging or detenting of the rotational output of the motor.

A scroll compressor is provided with structure that allows a reduction or modulation in mass flow capacity. Structure is provided for controlling the back pressure force tending to bias one scroll into other. This structure defines two distinct back pressure chambers. Pressure fluid is not supplied to at least one of the back pressure chambers during modulated operation.

A scroll compressor having a housing containing an orbiting scroll and a non-orbiting scroll each having a base formed with a free side and a compression side and having an involute extending generally normally from the compression side, each the involute terminating in an axially outer, substantially planar edge and having a radially outer inlet end and a radially inner discharge end, the scrolls being mounted within the housing in mating arrangement about a center axis of the involutes for relative orbital motion for compressing gas between the base and adjacent side portions of the involutes, the orbiting scroll having special bearing structure for eliminating the laterally directed tipping forces which are generally experienced by the orbiting scrolls of conventional scroll compressors, the bearing structure having a bearing hub integral with the discharge end of the involute of the orbiting scroll, the hub having a cylindrical bore oriented substantially normal to the compression side of the orbiting scroll for rotatably receiving an eccentric shaft section of a compressor crankshaft, bearing means formed axially thru the base of the non-orbiting scroll, a crankshaft having an axial section and an eccentric section, the axial section being rotatably mounted in the bearing and the eccentric section being rotatably mounted in the hub, whereby rotation of the crankshaft will move the orbiting scroll thru an orbit relative to the non-orbiting scroll to thereby generate compression pockets between both the base and the involutes.

A safety bumper pad includes a bumper pad, a mattress retaining sheet, and a plurality of positive locking straps. A bumper cover is sewn around a bumper cushion to form the bumper pad. The mattress retaining sheet is sewn on the bottom of the bumper pad such that a mattress may be inserted therein. The mattress retaining sheet is deep enough to allow the entire bumper pad to protrude above the mattress. A plurality of positive locking straps are attached to substantially the top of the bumper pad. The positive locking straps include a strap portion, a female locking member, and a male locking portion. The female locking member is attached to one end of the strap portion. The male locking member contains a loop section through which the other end of the strap portion is inserted. The male and female locking members are pulled around at least one crib rail and then the male locking member is inserted into the female locking member. A loose end the strap portion is pulled tight to hold the bumper pad against the crib rail.

A device for electrically connects a plurality of electrical devices with a source of electrical energy. The device includes a base, a primary power cord, a primary reel, the capability of receiving a plurality of separate conductors, and at least two secondary reels. The primary power cord is adapted for connection with the source of electrical energy. The primary reel is attached to the base and has the primary power cord at least partially wound thereon. The primary reel is biased in a first direction and rotatable in the opposite direction which permits extension and retraction of the primary power cord. Each of the plurality of separate conductors is adapted for electrical connection with the primary power cord and adapted for providing a remote source of electrical energy to the electrical device. Each of the secondary reels include one of the conductors at least partially wound thereon for effecting extension and retraction thereof.

A scroll compressor having a housing containing a non-orbiting scroll and an orbiting scroll and a crankshaft having an eccentric mounted on the orbiting scroll, the non-orbiting scroll being fixed in operative position on the housing by a plurality of pairs of cooperating, mating key and keyway type components provided on the housing and non-orbiting scroll and mating with predesigned pressure contact, wherein all of the pairs have been mated with substantially equal pressure contact prior to fixing the positions of the pairs on the housing, and wherein the mated pairs allow axial compliance motion of the non-orbiting scroll while providing predetermined resistance to the motion.
