Title: Separator system for machinery coolant-lubricants has alarm system - indicating excessive pressure difference across filter and need for cleaning
Inventor: KOCZY BERNHARD
IPC: B01D17/12
Filed: 1990-04-14
Abstract: This is an arrangement for monitoring the behaviour of a separator for the regeneration of used emulsion, in particular coolant-lubricants. The separator outflow piping, for the regenerated emulsion, includes a fine-mesh filter. There is a device for measuring the pressure difference across the filter and for giving a signal if this difference exceeds a prescribed amount. The filter mesh and the prescribed pressure difference are chosen to suit the required quality of the emulsion. Variants claimed include several relating to the pressure-difference signal. USE/ADVANTAGE - Unlike other separator systems, the proposed system provides an indication of troubles in, or affecting, the separator. This allows an increased time interval between de-sludgings, without affecting the quality of the regenerated emulsion. It also increases the general reliability of the separator in respect of emulsion quality.

Inventor: RAUSER ULRICH
IPC: B25D16/00
Filed: 1991-10-25
Abstract: In order to synchronize switching from drilling to chiselling and vice-versa in a drilling and chiselling hammer, an axially movable sleeve (25) is capable of acting on spring-loaded switching members, i.e. a toothed wheel (16) and a retaining ring (26). The toothed wheel (16) meshes with the rotary motor drive and can be coupled by teeths (15, 17) to a rotary drive sleeve (13). The retaining ring (26) is linked by a pin (35) to the gear housing (3) so as not to turn and can be coupled by teeth (14, 31) to the rotary drive sleeve (13).  The modes of operation may be switched over without considering the position of the teeth. Another advantage of the invention is that the individual parts of the device are more simple and that the volume of the parts to be tempered is reduced.
