Title: Hinge fixture for door pivotable around horizontal axis - has Z=shaped formation of hinge component free arm allowing oven door to be releasably retained in oven frame slot
Inventor: GIRAUD HUBERT DIPL ING
IPC: F24C15/02
Filed: 1990-12-20
Abstract: The oven door (1) has a hinge housing (3) fitted to it. In this housing is the hinge axis or shaft with a return spring located. The shaft carries at least two hinge arms (5), and through the oven front (7) extends a middle bridge (9) of a Z-shaped formation of the hinge arm (5). The end section (92) of the Z-shaped formation supports from the inside and the other end section (93) from the outside on the oven front frame (7) by reason of the torque produced by the gravitational forces of the oven door. The Z-shaped formation (9) is guided through a slot (8) in the oven front frame (7), and supports via the middle bridge (91). In this way, the door is retained firmly on the oven by its own wt. USE - As a hinge fixture arrangement for an oven door which lowers around a horizontal axis.

Title: Contactless detection or adjustment of centering error for lenses - involves positioning surface w.r.t. fibre=optic sensor until received signal caused by surface rotation is sufficiently small
Inventor: MOLLENHAUER OLAF DIPL ING
IPC: G02B7/00
Filed: 1991-03-07
Abstract: A method of contactlessly detecting and/or adjusting the optical surface centreing errors involves rotating the surface. A specific arrangement of the surface (8) and a fibre optical sensor (14) is set up so that light from the sensor is reflected back from the surface as a periodic signal with the frequency of the rotary relative motion. The adjusted position and parameters are derived from the received signals and relative rotational position. The surface is dsplaced and tilted w.r.t. the sensor to reduce the extrema of the received signal's a.c. component. The process is repeated until the received signal is sufficiently small. USE/ADVANTAGE - Esp. for correcting centreing errors of optical lenses at reduced cost.

Title: Nozzle for RAM jet engine - uses suction effect to exclude acceleration to high speed for engine start
Inventor: WERDING HANS J
IPC: F02K7/12
Filed: 1991-04-02
Abstract: The ram jet engine has a self-starting nozzle made of sheet metal with a thickness of 0.5 mm. The nozzle has a circular corss-section and a curved longitudinal axisw with the inlet dia. (A) much larger than the jet outlet dia. (E). The shape of nozzle generates a suction force at the inlet, which makes the nozzle self-starting. A ram jet engine fitted with such nozzle does not need to be accelerated to a relatively high speed to generate the ram pressure which is normally required to make a ram jet engine self-sustaining. ADVANTAGE - No need for starter motor, or use of centrifugal forces.

Title: Extinguishing continuously fuelled fires at oil wells etc. - using enclosing jacket immediately after fire has been blown out by removal of oxygen@
Inventor: PIETZSCH LUDWIG DR ING
IPC: E21B35/00
Filed: 1991-04-05
Abstract: Process is for extinguishing continuously-fuelled fibres such as those at burning oil-wells. An enclosing jacket for preventing the surrounding air from reaching the fire, provided with a gas outlet, is used. Before the jacket is lowered over the fire, the fire is blown out by a brief removal of oxygen. After this, gas leaving via the gas outlet is, at a safe distance from the outflow of fuel, ignited and flared off. The several features and variants include bringing to the site of the fire, before the jacket is placed, a work shield or housing whose protection allows preparatory work to be done before the extinguishing work. USE/ADVANTAGE - Improvement over methods in which enclosing jackets are used in extinguishing these fires.

Patent DE-4123479-A1 (DE)
Inventor: ROBILLARD CHRISTOPHE
IPC: G02B27/28
Filed: 1991-07-16
Abstract: The invention aims at improving the operational safety of lighting systems for polarized light. For that purpose, an indesirable direction of polarisation is rotated by deflecting means having a rough surface, thus allowing so-called quarter-wave plates to be dispensed with. In addition, the operational safety is increased thanks to the use of two independant light sources provided with their own focussing means. The light sources are further controlled by controlling means, thus reducing the load applied to the individual light sources. The invention is particularly useful for lighting liquid crystal light valves that form part of a projection system.

Title: Electromagnetically operable hydraulic control valve - regulates fluid pressure by means of damper integrated into hollow screw for adjustment of armature spring tension
Inventor: PETRI WOLFGANG
IPC: F15B13/044
Filed: 1992-05-09

Title: Safety locking system for discharge door of baling press - has sliding locking bolt that is mechanically locked and is released by actuation of stepping motor when press ram is withdrawn
Inventor: SCHAUTZGY ACHIM DIPL ING
IPC: B30B9/30
Filed: 1992-05-12
Abstract: The bolt (33), which holds the hinged discharge door (5) closed, slides through a housing (31) fixed to the press frame, and is locked in position by the engagement of balls (41) in a groove (40). Depression of the spring-loaded plunger (43) allows the balls to move inwards so that the bolt can be moved and the door opened. A motor (52) is connected to the press control panel and linked with the valve controlling the press hydraulic ram. A time delay relay prevents the motor from being actuated until the press ram has withdrawn and pressure in the baling chamber has been relieved. A limit switch sensing the presence of the door catch in the slotted end of the bolt (33) prevents operation of the ram when the door is open. ADVANTAGE - Low-cost system ensuring safe operation. Personnel remain safely distant from door under pressure.
