Abstract: Systems and methods include providing a tolerance ring in an electric drive motor assembly having a housing and a stator disposed within the housing. The tolerance ring is disposed within the housing and retains or secures the stator within the housing and control movement of the stator within the housing. The tolerance ring includes an annular ring-shaped substrate formed from a metallic material and a plurality of projections protruding radially inward from an inner surface of the substrate or radially outward from an outer surface of the substrate. The tolerance ring optionally includes one or more cooling features formed in the substrate and configured to promote cooling between a fluid disposed in the housing and the stator.

Abstract: A bearing including a generally cylindrical sidewall including an electrically conductive substrate, and an electrically non-conductive or low-conductive sliding layer coupled to the substrate, where the generally cylindrical sidewall includes a plurality of protrusions protruding radially inward or radially outward from a bore defining a central axis, where at least one protrusion is adapted to contact an opposing component such that at a point of contact the bearing has a void area free of sliding layer so as to provide electrical conductivity between the bearing and the opposing component, and wherein at least one protrusion has a spring rate of not greater than 30 kN/mm, such as not greater than 25 kN/mm, such as not greater than 15 kN/mm, or such as not greater than 10 kN/mm.

Abstract: A laminate includes a first layer of a first fluoropolymer. The laminate can further include a second layer of at least one ply of a fluoropolymer fabric overlying the first layer. The laminate can further include a third layer of a second fluoropolymer overlying the second layer opposite to the first layer. The laminate can have a strain of not more than 50% at a stress of 15 MPa as measured by DIN EN ISO 527 with a sample width of about 1 inch, at a clamp distance of about 50 mm, and a speed of about 50 mm/min. Embodiments of such laminates can find applications, for example, as diaphragm membranes, solenoid valves, conveyor belts, or bearings.

Abstract: Use of working fluids for energy conversion in a thermal Organic Rankine Cycle (ORC) process for combined generation of electrical and heat energy. The heat source used in the ORC process is in particular thermal water. The working fluids used in the ORC process are partially or perfluorinated hydrocarbons and/or partially or perfluorinated polyethers and/or partially or perfluorinated ketones. In some embodiments, the working fluid used is a combination of 1,1,1,3,3-pentafluorobutane and a fluorinated polyether having a molecular weight of 340 and a boiling point of 57° C. at 101.3 kPa, or a combination of 1,1,1,3,3-pentafluorobutane and at least one partially or perfluorinated ketone.

Abstract: Working fluid for the heat transfer, in particular for the heat transfer by heat pipes, containing or consisting of partially fluorinated and/or perfluorinated hydrocarbons and/or perfluorinated polyethers. Preferably, a mixture of pentafluorobutane and perfluorinated polyether is used as a working fluid.

Abstract: A refrigerant mixture that is suitable as a substitute for the refrigerant 1,1,1,2-tetrafluoroethane (R134a) in which the mixture contains or is composed of halogenated hydrocarbons having a GWP100 of not more than 150 and carbon dioxide. The refrigerant mixture is suitable for use as a refrigerant in air conditioning systems, especially for automobile air conditioning systems.
