Patent DE-4209790-A1 (DE)
Inventor: EILENBERGER GERT DR ING
IPC: H04Q11/00
Filed: 1992-03-26
Abstract: Prior art: multi-stage optical switches. Individual stages have different combinations of space-division, time-division and frequency-division converters. Technical problem: time-division conversions are urgently required but are very expensive to implement. Basic concept: time-division conversions only in the last stage, otherwise only space-division and frequency-division conversions. Solution: last stage contains space-division, time-division and frequency-division converters, the remaining stage in each case contains base-division and frequency-division converters. Advantage: no overtaking possible in multi-path connections in the switch. <IMAGE>

Title: Closure cap with elastic seal and safety pressure release - has indentation in inner bearing face of cap connecting with outside air and taking up seal section when pressure in container is too strong.
Inventor: AUER HELMUT
IPC: B65D51/16
Filed: 1992-08-14
Abstract: When the cap is fixed on the bottle neck the elastic seal fits tight between a bearing face on the inner cap wall and a sealing face on the bottle neck. The bearing face (7) has at least one indentation (9) which forms a hollow cavity and connects with the outside air. In the event of excess pressure inside the bottle a section of the seal enters the indentation to release a path to allow the pressure to escape. The cap (1) pref. has a stop (16) so that when the cap is inserted on the bottle neck it is restricted to a defined position. The seal can be designed so that it restricts the movement of the cap when fitting onto the bottle neck. The seal and cap can be made of the same material USE/ADVANTAGE - The extent of the overpressure which the seal lets escape is independent of the mfr. tolerances of the cap and the force applied when fixing the cap on the bottle neck.
Patent DE-4230775-A1 (DE)
Title: Compressing of waste, esp. paper, in passage press - wherein backward movement of waste in passage is prevented by plates attached at one edge to the inner passage walls
Inventor: WESTERFELD MANFRED
IPC: B30B9/30
Filed: 1992-09-15
Abstract: In a press for paper and other waste material, the material is fed from above into a press housing and is conveyed horizontally by a piston into a pressing passage. The piston reciprocates into and out of the press passage, and the compressed material is prevented from moving backwards by restraining elements built into the passage walls. The piston has lateral openings which permit the movement of these elements. The novel feature is that the restraining elements are in the form of metal plates (12) whose outer edges (18) retain the compressed material and whose inner edges are attached to the side walls of the press passage (4) and the housing (2), and which extend as far as the outermost position of the piston (5). These plates fit closely to the lateral openings in the piston. USE/ADVANTAGE - For compressing solid waste materials e.g. paper. The reliability and long life of the press are maintained while improving its operation so that breakdowns are reduced and maintenance is made easier and much more economical.

Patent DE-4236334-A1 (DE)
Inventor: TOPP RAINER DIPL ING
IPC: H03K17/14
Filed: 1992-10-28
Abstract: A monolithic integrated MOS high-level stage component, in particular a DMOS high-level stage, has a high-level stage element (10) provided with a GATE, a SOURCE and a DRAIN connection, as well as an overload protection arrangement. An integrated GATE pre-resistance (11) connects an outer GATE connection (Ga) of the high-level stage component to the GATE-connection (Gi) of the high-level stage element (10). The overload protection arrangement is integrated in the high-level stage component and has a level adapter stage (30) which causes the transmission characteristic curve of the high-level stage element (10) to be displaced by a defined voltage offset value when the GATE pre-resistance (11) is crossed by a defined current. A limiting stage (34) limits the cumulative value of the DRAIN-SOURCE voltage and of a voltage proportional to the DRAIN current to a predetermined value. An overload protection arrangement in a monolithic integrated form having an improved protective function may thus be achieved at a reduced cost, as the physical limitations of the semiconductor can be better used.

USE/ADVANTAGE - Provides short and compact stylus assembly enabling axial dimension of instrument to be reduced. Height of stylus point is self-adjusting due to spring to match variable stack thickness of recording charts.
