Title: Testing vehicle window sealing strips
Inventor: JUNKER BERND
IPC: B60J10/00
Filed: 1990-09-12
Abstract: A sealing strip (4, 5) is mounted on a platten 22 connected to a force measuring unit 20 and its initial height measured by a probe 40 extending through a hole 34 in a contact plate 32. Plato 32 is then lowered to compress the seal. The resultant force is measured by the unit 20 and plotted on a pen-recorder which shows how the force gradually reduces with time due to "relaxation" in the material of the sea caused by molecular adjustment and release of air or gas in its foamed construction. The shape of the curve, and the ratio of the forces at the beginning and end of a fixed period, indicate properties of the seal. The contact pressure is then removed and the height of the seal to which it resiles and the rapidity with which it reaches this height are measured. <IMAGE>

Title: A method and apparatus for controlling a robot
Inventor: MILBACH JOACHIM
IPC: B25J9/02
Filed: 1991-07-02
Abstract: A gantry robot is moved in synchronism with a moving workpiece such as a car body on an assembly line. The robot is coupled to the workpiece by a position transducer 14 through a mechanical, optical or other link 13. Signals from the transducer are used in position and speed control of robot movement. To reduce the signal processing time the characteristic values determined by the position transmitter are fed into a position control card of the robot control unit in the fine interpolation cycle. After completion of its assembly task, the robot returns upstream to work on the next car body. At the appropriate time, the robot is pre-accelerated to bring it into approximate synchronism with the workpiece. <IMAGE>

IPC: C22C11/06
Filed: 1992-12-22
Abstract: A Cu-Pb composite bearing has at least three layers including a backing metal, a bearing alloy layer formed on the backing metal, and an overlay or surface layer formed on the bearing alloy layer. The Cu-Pb bearing alloy contains 2 to 10% Ni and 0.05 to 1.0% B. A preferred composition of the Cu-Pb bearing alloy is from 0.5 to 8% Sn, from 15 to 30% Pb, 0.2% or less P, from 2 to 10% Ni, 0.05 to 1.0% B and the balance being Cu and any unavoidable impurities.
