Patent number: 5000228Abstract: Insulation sleeving, such as for providing thermal and/or electrical insulation for cables and cable connections, of the type comprising an inner sleeve of woven synthetic organic or inorganic fiber, such as fiberglass, and an outer coating of silicone elastomer. The woven fiber of the inner sleeve has a substantially open weave, i.e., the number of picks per centimeter is in the range of between about 2 and 9, andthe silicone elastomer of the outer coating has a reduced modulus of elasticity, such as between about 0.5 and 3.5 MPa at 100 percent elongation, and an increased tear strength, such as between about 5 and 45 KN/m. Insulation sleeving is elastically expandable to an extent such that its diameter can be increased up to twice its original unexpanded dimension without materially affecting the thermal, electrical and mechanical insulation properties of the sleeving thereby enabling a standard sized sleeving, i.e.Type: GrantFiled: August 16, 1988Date of Patent: March 19, 1991Assignee: Relats, S.A.Inventors: Jordi R. Manent, Ernest V. Montagut

Patent number: 4992314Abstract: Rubber compositions are disclosed which are capable of exhibiting superior adhesion and high water resistance in bonding rubbers to brass and to organic fiber cords and also to different rubbers. Such bonding characteristics can be obtained by the use of specified amounts of a selected class of organic sulfur-containing compounds combined with sulfur-curable rubbers, silica, resorcin donors and methylene donors. Hoses are also disclosed which have these compositions applied as adhesive layers.Type: GrantFiled: May 15, 1989Date of Patent: February 12, 1991Assignee: 501 Yokohama Rubber Co., Ltd.Inventor: Tomoji Saitoh

Patent number: 4992313Abstract: A fiber-reinforced plastic article having first, second, and third cylindrical portions is disclosed. A helical braid is applied along a first cylindrical portion as a first cylindrical sleeve which conforms to and encases the outside surface of said first cylindrical portion. The second cylindrical portion is passed through the filaments forming the braid and the braid is collapsed into a first, substantially flat, double-ply braided ribbon which is then wrapped about the outer surface of the second intersection portion. The helical braid is again applied along the first cylindrical portion and a second braided ribbon is then wrapped about the outer surface of the third cylindrical portion. The fibers are impregnated with a thermosetting resin which is cured to produce the article.Type: GrantFiled: June 21, 1989Date of Patent: February 12, 1991Inventors: James P. Shobert, Elson B. Fish
