Abstract: A method is provided for in situ cleaning of lubricated parts of a machine in which the machine is operated with a lubricating fluid that contains an effective concentration of a cleaning composition comprising a synthetic ester of a naturally occurring fatty acid for an amount of time sufficient to remove from the lubricated parts adhered debris which is not removed by the lubricating fluid conventionally used in the machine.

Abstract: A method for predetermining the controlled and uniform discharge rate of a fluid from a single lumen tubular body having passageways radially extending through the wall of the tubular body has been developed and is described. The method involves predetermining such parameters as the transverse cross-sectional areas of the passageways extending through the wall of the tubular body, the spacing of the passageways, the pressure at each of the passageways, and the rate of flow at each of the passageways. One specific preferred application of such a tubular body is an infusion catheter for delivering various fluids to designated areas of the body for either a therapeutic treatment and/or diagnostic purposes. For example, such a catheter may be adapted to deliver controlled and uniform quantities of thrombolytic agents, chemotherapeutic agents as well as such diagnostic agents as fluorescent dyes and radioactive agents.

Abstract: A butterfly valve or a similar quarter-turn valve is provided with a locking mechanism which permits the disc assembly to be rotated from the open position to the closed position, but prevents the disc assembly from being rotated back to the open position. The locking mechanism includes a cam carried on a rotatable stem supporting the valve disc assembly. The cam has a camming surface including a detent notch situated at a location corresponding to the open position of the disc assembly. A plunger, which is spring loaded into engagement with the camming surface, is urged into the detent notch when the disc assembly is rotated from the open to the closed position and prevents the disc assembly from being rotated back to the open position.

Abstract: Surfaces of hydrophobic polymers are treated to reduce their friction resistance characteristics when in contact with an aqueous environment by exposing the surfaces to an oxidation treatment, preferably by use of radio frequency glow discharge. This oxidation is followed by exposure to atmospheric air, until there is a substantial reduction in the air-water contact angle of the surfaces. The reduced friction resistance characteristics are important in aqueous applications where there is movement between the surfaces of two polymeric materials, such as in double slideable catheters and similar medical products. This process also provides lower coefficients of friction for general polymeric products in contact with water and aqueous solutions.

Abstract: A two-piece electrical connector means for detachably connecting an ignition cable or the like having a plurality of high tensile strength, nonconductive strands coated with an electrically conductive material to a mating stud terminal is disclosed.

Abstract: An insulated vehicle body, such as a refrigerated truck or trailer, has load carrying reinforcement beams in the roof structure with bottom slots accessible through openings in the ceiling skin to receive removable hangers that may be used to suspend meat rails or other articles from the roof structure.

Abstract: The disclosure relates to a load bearing, post-free sidewall for an over-the-road trailer or the like. A bottom rail of the sidewall is attached to the floor of the trailer and secures the sidewall thereto. Each of the sidewalls comprises a pair of substantially parallel, vertically extending, horizontally spaced and load bearing plastic panels having foam insulation disposed therebetween. The bottom rail member transfers loads thereon substantially equally to each of the panels of each sidewall.

Abstract: The disclosure relates to a meat rail support system for refrigerator trailers having post-free, foam-filled walls. An outer top rail of the trailer side wall is secured to the outer skin of the side wall. An inwardly extending flange is positioned above the side wall and is either integral with the top rail or riveted thereto for the acceptance of a meat rail support beam.In one embodiment, an inner side wall top rail of low heat conducting material, for example, FRP plastic, is secured to a plastic inner skin of the side wall and has an outwardly extending flange positioned above the wall. A meat rail support beam extends transversely across the trailer and rests on the flanges of the inner and outer top rails. Fastening means are located between the inner and outer skins of the side wall so as to transfer loads on the meat rail support beam relatively equally to both the inner and outer side wall skins.
