  • Publication number: 20240116159
    Abstract: A tool system for installing a parking pawl includes a tool that includes a base, a plate, and an actuator. The base includes a base surface configured to support a parking pawl in a predetermined position. The plate includes a protrusion that extends upward from a front portion of the plate. A rear portion of the plate is coupled to a front portion of the base. The plate is movable relative to the base between a retention position in which the protrusion is positioned to retain a pawl spring loaded on the parking pawl in a pretensioned state, and a release position in which the protrusion is configured to release the pawl spring. The actuator is operably coupled to the plate such that activation of the actuator moves the plate between the retention position and the release position.

  • Patent number: 6526764
    Abstract: Hydrofluorocarbon refrigerants are not soluble in hydrocarbon oil. Retrofitting refrigeration equipment with hydrofluorocarbons generally entails the use of expensive polyol ester (POE) lubricants. The invention provides hydrofluorocarbon refrigerant compositions that are soluble in hydrocarbon oil thus allowing for a simpler and less expensive retrofit option to the refrigerant user.

  • Patent number: 6516837
    Abstract: Provided are methods of introducing environmentally desirable refrigerants into refrigeration systems. The present methods involve recharging a refrigerant system that contains a chlorine-containing refrigerant and a lubricant comprising the steps of (a) removing the chlorine-containing refrigerant from the refrigeration system while retaining a substantial portion of the lubricant in said system; and (b) introducing to said system a composition comprising: (i) a refrigerant; (ii) a surfactant; and (iii) a solubilizing agent.

  • Patent number: 6500358
    Abstract: The present invention provides refrigerant blends which are replacements for chlorodifluoromethane(HCFC-22). The present blends have refrigeration characteristics which are similar to HCFC-22. The blends comprise from about 10 to about 90 weight percent of a first component selected from the group consisting of 1,1,1-trifluoroethane, difluoromethane, propane, and mixtures thereof; from about 1 to about 50 weight percent of a second component selected from the group consisting of hydrofluorocarbon having 1 to 3 carbon atoms, fluorocarbon having 1 to 3 carbon atoms, inorganic compound, and mixtures thereof having a boiling point at atmospheric pressure in the range from about −90 degrees C to less than −50 degrees C; and from about 1 to about 50 weight percent of a third component which is hydrofluorocarbon having 1 to 3 carbon atoms, other than 1,1,1-trifluoroethane, having a boiling point at atmospheric pressure in the range from about −50 degrees C to about 31 10 degrees C.

  • Patent number: 6355113
    Abstract: A non-aqueous cleaning process uses an organic solvent for removing soil or surface contamination from contaminated articles such as printed circuit boards which are cleaned by immersion into a sump compartment of a cleaning tank containing the organic cleaning solvent. The organic solvent is preferably a hydrocarbon solvent. The cleaned articles, now coated with the organic cleaning solvent, are then disposed in a rinsing sump containing a fluorocarbon based rinsing solvent having an affinity for the organic cleaning solvent. The organic solvent is thus removed from the articles which are then dried without waste water as in a conventional solvent vapor degreasing solvent process.
