    摘要: A thermally self-regulating elastomeric composition and heating element made therefrom. The composition includes a body of elastomeric material in which is distributed electrically conductive particulate material, such as carbon black. Short fibers are also distributed in the elastomeric matrix. In the disclosed invention, the short fibers are present in the amount of approximately 0.5 to 20 volume percent. In one alternate form, the matrix is foamed. Different arrangements of the electrodes in electrical conductive association with the thermally self-regulating elastomeric body are disclosed. Preferred proportions and characteristics of the particulate conductive material and short fibers providing optimum thermally self-regulating characteristics of the composition are disclosed.

    摘要: A manufacture of an impact-resistant power transmission belt tensile cord and belt using the same. The tensile cords of the invention are caused to have coordinated characteristics of toughness, elongation under load, shrinkage, and shrinkage stress so as to provide absorption of longitudinal and transverse impact shock forces to the belt during high power transmission therethrough, with minimized dimensional changes of the belt over the useful life thereof, permitting the belt to be utilized in multiple parallel drive applications in extremely rigorous environments with minimized maintenance. The tensile cords are adhesively coated, thermally drawn and set multifilament polyester cords.

    摘要: A toothed belt having a fabric adhered to the toothed portion of the belt formed of synthetic resin yarns having an ultimate viscosity of greater than approximately 1.30. In the illustrated embodiment, the yarns extending in the longitudinal direction of the belt are fully processed yarns. The cloth is preferably a woven cloth wherein one or the other of the weft and warp are wooly processed. The use of the disclosed cloth provides a substantial improvement in resistance of the belt to cracking and shearing of the teeth in use.

    摘要: A drive belt (10) having an elongated body (11) provided with tensile cords (12). The belt is provided with teeth, or cogs, (13) and a two-ply reinforcement is provided on the surface of the teeth, or cogs, including an inner layer (15) and an outer layer (17). The inner layer is formed of parallel yarn, or twine, elements (16), which may be spirally wrapped to extend in the longitudinal direction of the belt. The outer layer is formed of a woven or knit cloth, and in the illustrated embodiment, is formed of a sailcloth having a highly elastic warp extending in the longitudinal direction of the belt and an inelastic weft for providing improved transverse rigidity and strength. The first layer yarn (16) and second layer warp (19) preferably have a ductility of greater than 50%. A number of candidate materials for the high ductility yarns is disclosed.
