Title: Pistol operated by compressed gas - has safety pawl to prevent operation of striker when breech is retracted
Inventor: WESP HORST ING
IPC: F41A17/00
Filed: 1990-04-25
Abstract: The pistol, which is actuated by compressed gas, has a barrel (1) with an attached container (1a) for the high pressure gas. The container (1a) is connected by passageways (3) to the pistol breech. The flow of air is controlled by a valve (2) which can be opened by a spring-loaded striker (7) which, when released, strikes the valve rod (5). The striker is held in its retracted position by the trigger (8) and can be released by actuating the trigger. The pistol has a breech block (9) which is retracted by toggle levers (10) which are actuated by an arm (11) and a shaft (12). When the breech block is in the firing position a projection (19) on the arm acts on a pawl (13) and holds it clear of the striker. When the breech block (9) is retracted and the arm swung upwards the pawl is pushed upwards by the spring  (14) and holds the striker in its retracted position. USE - Pistol operated by gas pressure.

Filed: 1990-06-26
Abstract: A disc brake of the partial lining type for road vehicles, especially utility vehicles, uses lining pad holders with friction which are pressed by leaf springs against guide surfaces of lining housings to prevent the brake linings from chattering and to prevent the guide surfaces from being deflected. When fitted, the leaf springs (5) are pressed by means of a holding bracket (7) against the outer edge of a pad holder (1) introduced into the lining housing and where necessary also against the outer edge of a pressure distribution plate inserted in a housing, whereby there are window-like apertures (21) in the wings (23) extending laterally from the centre (15) of the leaf spring (5) which, with the leaf spring (5) under tension, can be guided via holding clips (19) formed on the outer edge of the pad holder (1) or the pressure distribution plate in such a way that the outer edges of the apertures (21), with the leaf spring in the released or partly tensioned state, engage with edges formed by rear cutouts (25) on the holding clips (19) and prevent any undesired release of the leaf spring. This prevents any sudden release which would present a danger for the operating staff when the leaf spring (5) is removed.

Patent DE-4100242-A1 (DE)
Title: Treating liquids contaminated with oils, esp. emulsions of oils - in which carry-over of oil in the vapour evolved in evaporative oil-water separator is prevented by using centrifugal separator
Inventor: BRITZE RICHARD ING GRAD
IPC: B01D17/00
Filed: 1991-01-07
Abstract: In the treatment of liqs. contaminated with oils by evapn., the parameters of the evapn. process (stages I to IV) are chosen so as to limit the oil concn. in the vapour evolved, principally by keeping the oil concn. in the liq. being treated below a max. allowed level. The liq. is then taken to a separator in which oil is removed from it, and the remaining liq. is the further evaporated. The proposed max. allowed oil concn. is 20%. USE/ADVANTAGE - Used in the treatment of oil-contaminated liqs., such as oily waste water which must have the oil removed before it can be taken to a waste water treatment plant. The essence of the invention is that the oil is removed from the water and concentrated by evaporation to the required 98% oil content, without the need to evaporate a liq. with a high oil content. This is an advantage since the evapn. of liqs. with high oil content inevitably involves the prodn. of an undesirable level of oil carry-over in the vapour evolved during evapn.. This is avoided by using a separator to remove oil from the water once a certain level of oil concn. has been reached in the evaporation equipment.

Title: Automatic atomic spectroscopic analysis of multi-component soln. - by set programme starting with known data and producing comparison standard
Inventor: NAUMANN BERND DIPL PHYS
IPC: G01N21/67
Filed: 1991-01-24
Abstract: For simultaneous automatic determnm by atomic spectroscopy of the elements present in a soln, the first of six process stages extracts from information sources the input data, spectral channels, and lines, and starting values for technical parameters. A second stage uses these data to produce a comparison standard from a comparison soln. From these stages a testing and control programme is derived for adjusting the appts parameters to permit correction by the comparison standard. The data are then supplied with details of objective and of relevant regulations. The fifth stage uses results to relate the objectives to the appts parameters and their limiting values, before finally the results are delivered to an information store, eg for future use. ADVANTAGE - Produces results with adequate sensitivity and speed without extensive addns to appts.

Patent DE-4125448-A1 (DE)
Inventor: BAIER JOACHIM
IPC: E05B85/02
Filed: 1991-08-01
Abstract: An electromotor actuator for the central door locking system of a motor vehicle has a housing and a first bolt that can be moved by a first electromotor between two end positions and that can be linked to a door lock of the motor vehicle, regardless of its direction. The bolt is preferably decoupled from the electromotor in its end position, so that it can be easily moved by hand between its end positions. This electromotor actuator comprises an anti-theft protection in that it makes it impossible to unlock the doors of the vehicle by actuating the inner locking handles once a window pane has been broken in. The parts of the actuator cannot be subjected to high forces when the inner locking handles are actuated. Finally, the doors may be unlocked from the outside even when the anti-theft protection is in force. For that purpose, a second bolt may be coupled to the first bolt by a catch movably guided on one of the bolts transversely to the direction of movement of the bolt. When loaded by a spring, the catch engages the other bolt, and it can be moved back by a second electromotor against the loading force of the spring from the coupling position in which it engages the other bolt into an anti-theft position, by means of a control element. In said position, the catch, together with the bolt up on which it is guided, can be moved away from the control element.__________________________________________
