  • Belt profile and profiled belt
    Patent number: 8567593
    Abstract: This invention provides a belt profile and profiled belt that can be easily mounted to and detached from a toothed belt. Specifically, a profile body and a claw section are integrally formed via a connection section. A side edge section of the toothed belt is inserted between the profile body and the claw section from an inner side in the belt width direction. The profile body is arranged on a rear surface side of the toothed belt. The claw section is arranged at the side edge section, on the tooth surface side. The connection section passes outside the side surface of the toothed belt. The profile is mounted on the toothed belt by engaging the claw section with a belt tooth while the profile body and the claw section sandwich the side edge section. The profile is removed from the toothed belt by performing these procedures in reverse order.

  • Safety and indicator apparatus systems and methods for high pressure conduits
    Patent number: 8561647
    Abstract: A pressure-relieving safety assembly, comprising a sleeve and collar, protects against human injury and loss of life by blocking flow of fluid from a ruptured high pressure conduit and provides pressure relief for escaping fluid. This pressure-relieving assembly includes a sleeve that encircles the high-pressure line and is secured to, at one or both ends of the line, a coupling. The sleeve is secured to the coupling(s) by a collar having raised portions that provides a path for fluid that has escaped from the conduit at a burst or pin-hole failure location, to flow towards the ends of the conduit, indicating to the user that a conduit failure has occurred. The sleeve lowers the fluid velocity while the path provided by the collar prevents the fluid pressure from building up behind the sleeve.

  • METHOD OF MAKING OPEN-ENDED THERMOPLASTIC BELTING
    Publication number: 20130153126
    Abstract: A system and method of making an open-ended, reinforced, layered belt having a profile layer, a top layer material, and tensile cords fully encapsulated there between. The method includes engaging portion of the profile layer on a rotatable cylindrical mandrel with an engaging roller, disengaging with a take-off roller, and applying and fusing the cords to the profile layer at a desired cord spacing there between. The cord may be fused by melting the profile layer surface with a heated plow and/or with heated cord. The cord is then covered with the top layer material in a lamination step involving heating to melt at least a portion of the top layer and pressing it to fuse it to the reinforced profile layer. Lamination may be done downstream or directly on the mandrel.
