    Abstract: An improved electric field dependent fluid and method of preparing the same for use at temperatures in excess of 100.degree. C. (typically 120.degree. C.) without releasing water comprising: a nonconductive liquid phase; and a dispersed particulate crystalline zeolite phase (e.g., M.sub.(x/n) [AlO.sub.2).sub.x (SiO.sub.2).sub.y ] wH.sub.2 O where M is a metal cation or mixture of metal cations of average valence charge n, x and y are integers and the ratio of y to x is from about 1 to about 5, and w is a variable). Such field dependent fluids are particularly useful in automotive and/or other high temperatures applications.

    Abstract: Self-lubricating bearings, such as journal-type bearings are obtained by molding under pressure at elevated temperatures a substantially homogeneous blend of from about 70 to 95% of an ultra high molecular weight ethylene polymer and from about 5 to 30% of a normally solid lubricant which can be a wax, fat or mixtures thereof, or a mixture of either or both of these lubricants with a grease. The bearings exhibit excellent dimensional stability, good wear resistance, and a surface which is not oily to the touch. The bearings are self-lubricating, slowly releasing lubricant at temperatures developed in ordinary use.
