Abstract: A captive ball and end connector assembly having an annular bearing half positioned within the cavity is disclosed. The bearing half has an inner spherical surface on which are disposed a plurality of crush elements or ribs, and a bottom planar surface on which is disposed an annular crush element or rib. The plurality of crush elements crush against the spherical surface of the captive ball, and the annular crush element crushes against an annular shoulder in the cavity to retain the ball within the cavity with a zero clearance. A ball retaining ring is disposed within a groove in the cavity and bears against the bearing half to hold the ball firmly in the cavity.

Abstract: An adjustable lower limb prosthesis has a pylon connected to both a prosthetic foot and to the stump adapter by way of a foot/pylon joint and a pylon/stump joint, respectively. Each of the joints is similar and includes a tapered socket holding a truncated conical wedge sleeve. The wedge sleeve has a bore which may be angled with respect to the cone axis, and into which the pylon is fitted. A cap locks the wedge sleeve in the bore and locks the pylon in the wedge sleeve. For adjusting the prosthesis, a set of wedge sleeves are available to the prosthetist, each having a bore with a different offset with respect to the conical axis of the sleeve. The prosthetist selects the appropriate sleeve based upon a prior determination using a temporary pylon and an alignment adapter. The correct foot wedge sleeve and circumferential alignment of the wedge sleeve are set with the aid of discs having offset holes.

Abstract: A compound shift lever mechanism employs a noise and vibration damper assembly for isolating an upper shift lever from a lower shift lever of a transmission. In a preferred form, the levers are held in spaced, coaxial alignment for unitary movement in a plurality of planes by a damper which comprises two parts. The first part is a cylindrical elastomeric sleeve defining axially spaced female end portions comprising bores which frictionally overlie and snugly encase the two lever end portions which extend thereinto. The second part is a cylindrical metallic shell which circumferentially encapsulates the elastomeric sleeve which contains the respective ends of the upper and lower levers. The shell thus radially encapsulates both of the end portions, as well as the sleeve, which incorporates a midportion containing a radial internal barrier to prevent direct physical contact between the extremities of the levers.

A plurality of rib members project from the body member into each of the cavities, and are deformable under pressure to vary the size of the cavities.

Abstract: An electrical connector for connecting a first conductor to a second conductor. The electrical connector includes a generally C-shaped body which defines first and second conductor receiving cavities for accomodating the respective conductors. The body member is provided with an opening communicating with the conductor receiving cavities, by means of which the condutors are adapted to be positioned within the cavities. An integral hingedly connected retaining member is associated with one of the conductor receiving cavities whereby, once a conductor has been placed in the latter cavity, the retaining member may be manually rotated to a position wherein it secured the condcutor in the cavity. The connector is then intended to be placed over a second conductor, such that the second conductor is received in the other conductor receiving cavity. The connector is adapted to be compressed, by means of a compression tool, so as to substantially close the opening in the body member.

Abstract: The method for producing the transmission device including coupling means connected to a sleeve comprises forming a collar from an apertured blank of the coupling means and cold forming projecting portions on the outer surface of the collar for connecting the collar to rotate with the sleeve. The projecting portions may be formed by expanding the collar in a die from which die the collar is removed before connection to the sleeve. Alternatively, the projecting portions may be formed by radially expanding the collar in the sleeve whose inner surface has projecting portions which form the projecting portions of the collar upon contact with the collar during the expansion of the latter.

Abstract: A connector is disclosed which includes an electrically conductive compression barrel and a deformable core grip which includes an inner sleeve and three longitudinally extending lobes projecting radially outwardly from the sleeve. The core grip fits over the projecting end of the reinforcing core member in a cable, and the end of the cable with the core grip thereon and a length of the cable with conductor strands thereon fit into the end of the compression barrel which is crimped against the core grip and against the conductor strands. Crimping produces a strong mechanical connection between the core grip and both the cable core contained therein and the surrounding compression barrel, and produces a good electrical connection of the compression barrel to the conductor strands on the cable.

Abstract: A cylindrical metallic sleeve has opposite end portions and a cylindrical body portion with a longitudinal passageway for receiving the end portions of a conducting cable in overlapping relation. A shaped annular portion is positioned adjacent the sleeve end portions and include an inner, outwardly flared surface and an outer cylindrical surface that intersect in a rounded end portion. The outer cylindrical surface is planar and positioned substantially parallel to the sleeve cylindrical body portion so that the insulation surrounding the cables adjacent the sleeve end portions is not abraded upon flexing the spliced cable. The flared inner surface is removed from contact with the overlapping cable end portions in the sleeve to permit flexing of the cable end portions therein without abrading the cables. The sleeve body is crimped into frictional engagement with the overlapped cable end portions.
