All types of abrasive particles can be used. Disintegrated material is dry mixed with oil-resistant grade of rubber, using an abrasive content to suit the end application e.g. 40-70 vol.%, the binder remaining low e.g. max. 15 vol.%. ADVANTAGE - Abrasive particles in the product yield successively under load. Prods. are resistant to oils (and hence to cooling lubricants).
Patent DE-4117455-A1 (DE)
Title: Spring system for wheel support on motor vehicles
Inventor: RUNKEL WALTER
IPC: B60G17/056
Filed: 1991-05-28
Abstract: The hydraulic medium, during springing in and out, flows backwards and forwards via a hydraulic connection between the spring legs (2,4) and at least one hydro-pneumatic spring accumulator (22,20) contg. a compressible medium. The spring accumulator, by compression of the compressible medium, produces a hydraulic pressure, which affects the force of the spring legs via the piston activation (8).     During the springing out of the spring legs, two at least timewise varying hydraulic pressures prevail in the legs and in the spring accumulator, whereby the closure and opening of the connections (16,18) between the spring legs and the spring accumulator are automatically controlled by the difference in the hydraulic pressures (p1,p2) in the legs and the accumulator.

Patent DE-4237368-A1 (DE)
Inventor: NEHL WOLFGANG
IPC: B65D85/575
Filed: 1992-11-05
Abstract: Containers having a fastening base are known which can be locked via a connecting piece into insertion apertures which are arranged on a lid which is mounted on the rear of the casing. This fastening base support which is situated outside the centre of gravity of the container causes vibrations and increases the level of load on the fastening base. To avoid these disadvantages, a container is proposed which has a fastening base (1) which has, on each of its two lateral surfaces, a holding strip (5), which strips engage in guides (6) of the container casing which extend into the holding strips. Furthermore, there are arranged on the fastening base (1) further guiding surfaces (7), one guiding surface being formed by a bridge-like web (8) which is provided with teeth (9) and presses in a resilient manner against a toothed strip (10) which is arranged on the container casing. The container may, moreover, be composed of an upper part and a lower part which are connected via a joint and can be locked at different angular positions with respect to one another. <IMAGE>
Patent DE-4237634-A1 (DE)
Inventor: ROSENTHAL HANS-DIETRICH
IPC: H04N5/63
Filed: 1992-11-07
Abstract: A video receiver with a switched-mode power supply (6) for generating operating voltages which are DC-isolated from the power mains contains on the mains-connected primary side of the switched-mode power supply a receiving decoder (28) for receiving and decoding remote control signals for switching the video receiver between operating mode and standby mode. In standby mode, the switched-mode power supply is completely de-energised which has the effect that a demagnetising device (18) for the picture tube of the receiver is also de-energised via a triac (19) which is controlled by the input current (Iw) in the mains feedline (20) to the power supply (3) to the switched-mode power supply. The receiving decoder (28) is fed from a transformerless standby power supply having a low active power dissipation, which is independent of the switched-mode power supply. <IMAGE>
