    摘要: In the process of manufacturing a refrigeration oil where an oil stock is dewaxed by forming a complex with urea in the presence of an activator, the improvement of adding hot vacuum gas oil to the separated urea complex whereby the activator is flashed off and is recycled for reuse and the slurry of the urea complex in the gas oil is treated with hot water to break the adduct and separate a water-urea mixture and oil and paraffin. The improved method enables accurate and uniform temperature control and degradation of urea is suppressed.

    摘要: A low-mass roller is disclosed comprising a cylindrical body formed of polymeric material and having an exterior surface, first and second open ends and defining an interior tubular space along a longitudinal axis therethrough for receiving an axle; and an outer shell formed of thin metal covering the exterior surface of the cylindrical body. In another aspect, the outer shell of the low-mass roller comprises an assembly of first and second tubular shells having inside diameters, equal within a predetermined tolerance, at first respective ends thereof, wherein the first respective ends are joined together and welded. The assembly of the first and second tubular shells includes a weld ring disposed between and nested within the first respective ends of the first and second tubular shells such that the shells are held together in alignment during the welding process.

    摘要: The universal joint is provided for use with power drive tools. A driving member (12) is provided having a bore (16) at one end for receiving a drive member and a cavity (18) at the other end. A driven member (14) is provided having a quadrified ball (20) at one end and a socket receiving member (22) at the other end. The quadrified ball (20) has quadrified sides (40), a spherical head (42) and spherical corners (44). The quadrified side (40) contains sloped portions (46). The cavity (18) contains a base (54), a square cross-sectional area (48), radius corners (56) and a spring groove (66). The quadrified ball (20) is held in place in the cavity (18) by means of a "C" spring (68). The "C" spring (68) fits in spring groove (66). Disposed at the base (54) of the cavity (18) is a plug compression washer (60) made of a compressible polymer. Disposed between plug compression washer (60) and the head (42) of quadrified ball (20) is a plug tension washer (62). The plug tension washer (62) comprises a cylindrical disk with a frustroconical end and a planar end. The plug compression washer keeps pressure on the quadrified ball (20) against the "C" spring (68) such that the driven member (14) will remain at an angle at which it is placed. The plug tension washer (62) accepts the friction from the quadrified ball (40) as it rotates at its articulated angle.
