Title: Dental articulator with two swinging arms - has arms connected by ball joint which permits rotational and sliding movement but prevents any lateral movement
Inventor: LANG HANS WALTER
IPC: A61C11/06
Filed: 1992-04-02
Abstract: A dental articulator, when in its working position, has two arms (2,3) which extend forwards. One of these arms can be swung about a horizontal axis (5) and is mounted in two bearings (11,12) which permit both rotational and sliding movement. Each bearing is formed by a pivot pin with a ball end which co-operates with a specially shaped surface which permits the required rotational and sliding movements. Any lateral movement of the arm is prevented by the side wall (39) of each bearing housing. USE/ADVANTAGE - Production of dentures. The device simulates the relative movement of a patient's jaws.

Inventor: JAEGER WOLFGANG DIPL ING
IPC: D01H4/12
Filed: 1992-06-12
Abstract: A process and device for reducing power consumption in the operation of spinning components are applicable to the spinning rotor drive in OE spinners or the spindle drive in ring spinners or flyers. The purpose of the invention is continuously to keep the power consumption low in the operation of spinning components. This purpose is achieved in that the pressure between each spinning component and the indirect drive system is controlled dependently upon the momentary difference between the rotations speeds of the spinning component and the indirect drive system during stationary operation at rated speed or on changes in speed so that the slip between the indirect drive system and the spinning component remains constant in time.

Patent DE-4329339-A1 (DE)
Inventor: BARTSCH ROBERT
IPC: B02C17/18
Filed: 1993-08-31
Abstract: The invention relates to an agitator mill which, on the outlet side of the grinding space, has both a static separating arrangement and a dynamic separating arrangement. These two separating arrangements complement one another ideally as, in the start-up phase, in particular the dynamic separating arrangement ensures a fault-free start while, in running operation, the static separating arrangement enlarges the overall effective passage opening in a desirable manner and thus leads to low pressure in the mill. The agitator mill according to the invention is thus characterised by high operational safety, low maintenance expenditure, low wear and universal applicability. <IMAGE>
