Patent number: 4431698Abstract: A low-friction, water- and steam-resistant packing suitable for both static and dynamic applications includes inorganic fiber selected from the group consisting of chemical, electrical, structural and alkali resistant glasses, ceramic, quartz, carbon and graphite materials, and dispersed and dried, but unsintered, polytetrafluoroethylene (TFE). The packing is essentially free of wetting agent and is prepared by combining the inorganic fiber with a TFE dispersion containing a wetting agent and heating the resulting combination to a temperature high enough to decompose the wetting agent but insufficiently high to sinter the particles of the dispersion.Type: GrantFiled: September 30, 1982Date of Patent: February 14, 1984Inventors: Edward M. Case, Chester S. Hopper

Patent number: 4395458Abstract: For use in a stringed apparatus, such as a tennis racket, a synthetic string having a cross-sectional diameter between about 0.025 and about 0.08 inch and comprising a plurality of fused, entwined filaments which are composed of a polyamide, such as nylon, impregnated with from about 0.05 to about 2.0 weight percent graphite particles having cross-sectional diameters ranging from about 0.1 to about 2.0 microns. To make the string, polyamide is heated to a temperature between about 300.degree. and 550.degree. F., preferably between about 450.degree. and 500.degree. F., mixed with graphite particles present at a concentration sufficient to promote cross-linkage of the polyamide substantially in the absence of cleavage, filtered, nozzle extruded into filaments, cooled, prestressed, and then fused into a string. A string having a cross-sectional diameter between about 0.05 and 0.06 inch exhibits a tensile strength greater than about 60,000 psi, modulus of elasticity less than about 0.3.times.10.sup.Type: GrantFiled: August 17, 1981Date of Patent: July 26, 1983Inventor: Ben T.
