Title: Pressure butt welding of chain links - where the surfaces are previously flattened by mechanical compression and two=stage application of electric current
Inventor: EXNER KARL-CHRISTOPH DIPL ING
IPC: B21L3/00
Filed: 1979-05-25
Abstract: Method of pressure butt welding of chain links is described in which heat treatable steels contg. >0.15% C and >0.5% Cr can be used to produce high strength chains. The process comprises two steps, in the first of which the surface faces to be joined are smoothed by application of a forging current of 0.5kA/mm2 lasting two periods together with a compressive stress on the surfaces in contact of 45 kp/mm2. The second step comprises application of an initial welding current of 0.75 kA/mm2 while a pressure of 40kp/mm2 is reached over 4 periods, due account being taken of the kinematics of the mechanical-hydraulic drive of the chain welding machine, so that no sweating out of liq. phase occurs from the joint. Oxide formed on the surface of the steel during welding does not become emulsified with the liq. metal in the joint, hence the oxide does not penetrate the joint to cause weakening.

Title: Method for detecting defects on motor vehicle tyres, and device for carrying out the method
Inventor: ENGLING WOLFGANG ING GRAD
IPC: G01M17/02
Filed: 1981-04-25
Abstract: The invention relates to a method for detecting structural defects and material defects in the sidewalls of motor vehicle tyres, in particular constrictions, blisters and undulations. In the method, a motor vehicle tyre is clamped on a rim device, subjected to a constant internal air pressure and set rotating uniformly. So that it is possible using such a measuring method to eliminate the disturbing influences which falsify measurement of the actual defects of the strength carrier and yet to obtain information on the fabric layer, it is proposed according to the invention that at least one of the tyre side walls is pressed in with a constant compression/jounce, that the pressure fluctuations are measured and that the structural defects of the tyre determined thereby are classified by size and/or direction. In this case, the device for carrying out this method is characterised in that there is arranged next to at least one side wall (20) of the tyre (7) at least one pressure device (25a, 25b) which can be moved in the direction of the axis (27) of rotation of the tyre (7) and has a roller (2a, 2b) mounted in a freely rotatable manner, at its end assigned to the side wall (20) of the tyre (7). <IMAGE>
