Patent number: 5551138Abstract: A process for encasing articles, particularly encasing cable splices, cable termination, a radially expanded tube made of a rubbery elastic material is positioned on the article. The tube is maintained in the expanded condition by a tension medium in the form of a plastic tube attached to the outer surface of the tube. The attachment between the surface of the tube and the tension medium is removed for the purpose of resetting the tube. The resetting is accomplished by cooling the plastic tube to a sub-ambient temperature thereby destroying the plastic tube.Type: GrantFiled: June 5, 1995Date of Patent: September 3, 1996Assignee: kabelmetal electro GmbHInventors: Franz Grajewski, Horst Matzat

Patent number: 5493765Abstract: A method is indicated for producing lengthwise waterproof cables, with a jacket that is formed around the transmitting elements containing the core. The voids in the core and between the core and the jacket are filled with a viscous sealing material, which is pumped from a storage container by a feed pump driven by a speed-controlled electric motor, and supplied to a pressure chamber. The core is passed through the pressure chamber so that the voids in the core are filled with the viscous sealing material. The pressure in the pressure chamber is continuously measured and is kept constant with a regulator. Sealing material leaving the pressure chamber is directed to a catch-container equipped with a level switch. From there it is supplied to the pressure chamber by a feedback pump driven by a speed-controlled electric motor, which is switched on and off by the level switch.Type: GrantFiled: November 28, 1994Date of Patent: February 27, 1996Assignee: kabelmetal electro GmbHInventors: Wolfram Klebl, Gunter Titze

Patent number: 5327637Abstract: A process for repairing the winding of an electrical linear drive having three winding strands formed of electrical cables which meander in the grooves of an inductor belonging to an elongated stator. To correct a defect in one of the winding strands, the respective cable is first removed from the grooves of the inductor in the defective area. Then, a section of predetermined length of the cable containing the defect is cut from the winding strand. The removed section of the cable is then replaced by a length of prefabricated cable of suitable length and shape, and the repaired cable is then reattached to the grooves of the inductor.Type: GrantFiled: January 28, 1993Date of Patent: July 12, 1994Assignee: kabelmetal electro GmbHInventors: Otto Breitenbach, Hermann Mollmann
