  • Patent number: 4255137
    Abstract: A heating device, particularly useful for heating the end portions of hollow elongated objects such as thermoplastic hose or tubing, comprises an enclosure for substantially surrounding the end portion of the object, means for substantially immobilizing the end portion within the enclosure and means for directing a stream of heated gas around the inside and outside of the object along the length of the end portion. In a preferred embodiment, the enclosure is an insulated metal circular cylinder having at one end apertures for receiving thermoplastic hose and controlling gas flow. At the other end, the enclosure has an apertured conical member for insertion into the hose to immobilize it in axial alignment with the cylinder.

  • Patent number: 4034617
    Abstract: Conveyor belting ends, each comprising a pair of carcass plies separated by an intermediate elastomeric ply and enclosed by a pair of outer rubber plies, are spliced by removing material from various plies to expose one surface of each terminal portion of the carcass plies. The two belting ends are then interfitted, after the application of tie gum to exposed surfaces, such that each carcass ply terminal portion overlies the terminal portion of the associated carcass ply on the other belting end, thereby assuring two uninterrupted carcass plies at the longitudinal location on the belt where each carcass ply is severed.
