  • Caterpillar traction apparatus
    Patent number: 8663528
    Abstract: A caterpillar traction apparatus (110), wherein two pairs of pulleys (122 & 123, 132 & 133) can be driven at different speeds, so that the linear member (40) being driven by the mechanism is subjected to either compression or extension forces.
    Type: Grant
    Filed: November 19, 2010
    Date of Patent: March 4, 2014
    Inventors: Peter David Jenkins, Daniel Owen Jenkins
  • Apparatus and method for forming annular grooves on the outer surface of a cable or tube
    Patent number: 8465235
    Abstract: The present invention provides an apparatus (100) for forming circumferential grooves (14) in the exterior surface of a linear member (10), such as a tube. The grooves are formed by rotating a cylindrical cutting element (120) around the tube such that cutting means in the cylindrical cutting element form the grooves. One rotation of the cylindrical cutting element causes multiple grooves to be formed in the surface of the tubes.
