  • Method of installing an optical fibre unit in a tube
    Patent number: 6385378
    Abstract: A method for installing a lightweight optical fiber unit, preferably less than approximately 10 g/m, into a tube, by pulling the optical fiber unit through the tube using a pulling member. The pulling member may be attached to the optical fiber unit by a braided sheath. Alternatively, the pulling member itself may be a braided tube.
    Type: Grant

  • Propellable optical fiber cables
    Patent number: 4930860
    Abstract: An optical fibre cable comprises a plurality of optical fibre structures each of which comprises an optical fibre surrounded by at least one sheath layer. The optical fibre structures are separably held together side-by-side. The optical fibre cable is propellable along a tubular pathway by fluid drag of a gaseous medium passing over the cable, and each of the individual optical fibre structures is preferably also so propellable when the said structures are separated from one another.

  • Femoral stem prosthesis
    Patent number: 4681590
    Abstract: A femoral stem prosthesis designed for secure fixation to the walls of the intramedullary canal of the femur. The prosthesis has an elongated stem portion, with a ball-shaped head, which carries one or more elongated resilient spring strips which are acted upon by an adjustable screw actuator to cause the spring strips to bow outwardly into engagement with the canal walls.
