Title: Brake and/or drive dynamometer with detection of the transverse force
Inventor: WEINLICH LEOPOLD
IPC: G01L3/16
Filed: 1993-02-26
Granted: 1995-01-05
Abstract: A brake and/or drive dynamometer, consisting of a stator and a rotor, is fastened to a fixed structure in such a way that the unit formed by the stator and rotor can be deflected with respect to two axes. The deflections about the two axes are detected with the aid of two separate force measuring devices, in order to be able to detect both the torque introduced into the rotor and that transverse force which, for example, would act on the axis of the rotor as a result of stresses or transmission faults and would lead to a measurement error.

Title: Working up waste material for recycling
Inventor: RATJEN WERNER
IPC: C04B18/02
Filed: 1994-09-27
Granted: 1995-12-21
Abstract: Scrap material is comminuted and thoroughly mixed together in a first step before being mixed with water and cement in a second step. The cement mass is then pressed through holes in a disc to produce rod shaped material with an increased temperature. In a fourth step the material is cooled and broken up. The fifth step involves encapsulating the particles in water glass and after setting encapsulating in a water-cement mixture. The sixth step involves encapsulating again in water glass and then encapsulating in a sand, cement, water mixture to produce the pellets which are allowed to harden in the final step in air.
