Patent DE-3742558-A1 (DE)
Title: Plant box or the like for a false floor
Inventor: BRUECKNER GUENTHER DIPL ING
IPC: A01K63/00
Filed: 1987-12-16
Abstract: Until now, plant boxes, flower boxes or the like have simply been erected on the false floor at the desired places. If, however, this floor has a carpet covering, this method gives rise to pressure points and discolorations which become visible in the event of movement or removal of the boxes and impair the appearance of the false floor. The invention avoids this problem by the plant box (17) being integrated into the false floor. In this connection, the plant box (17) extends in a free space between the foot supports (11) downwards into the cavity under the false floor. The plant box (17) has a laterally projecting, circumferential edge (19), the external dimensions of which correspond to the modular dimension of the false floor panels (10) or a multiple thereof. The plant box (17) is mounted with this edge (19) on the foot supports (11) and/or with its bottom (20) on support brackets (21) which are fastened on the foot supports (11). In this manner, a flush transition from the plant box (17) to adjacent floor panels (10) is achieved. The plant box (17) can be installed anywhere in the false floor by removal of a floor panel (10). <IMAGE>

Patent DE-3802333-A1 (DE)
Title: Centrifuge for dewatering solid/liquid mixtures
Inventor: VIERTEL RUDOLF
IPC: B04B15/12
Filed: 1988-01-27
Abstract: When dewatering solid/liquid mixtures in centrifuges, in particular in solid-bowl worm centrifuges with adjoining screen casing component, in addition to post-dewatering the materials which are pre-dewatered in a solid-bowl component are also frequently washed on the screen casing component in order to free these materials of undesired accompanying materials. In previously known centrifuges, the material which is respectively separated from the liquid in the centrifuge is washed at the start of the screen. However, in many cases this is inadequate and does not permit optimum adaptation of the washing process to the solids to be washed. According to the invention, at least one annular slide (13, 14) which is adjustable in the axial direction is arranged in the hollow shaft (3) in the region of the screen casing component (2), the said annular slide (13, 14) closing or uncovering the jet-shaped openings (12) in the hollow shaft (3). In this way, optimum adjustment and adaptation of the washing zone to the respective solids to be washed is made possible from the outside before the solids are discharged from the centrifuge. <IMAGE>

Title: Device for releasing an aircraft rescue parachute from a container
Inventor: SEIFFERT WULF
IPC: B64D17/80
Filed: 1988-04-02
Abstract: The invention relates to a device for releasing an aircraft rescue parachute from a container, which is provided with a closure flap, by means of a propellent gas. This propellent gas which is located in a cartridge (3) on or in the container produces an overpressure, which forces the rescue parachute out of the container, under the rescue parachute after the cartridge (3) has been opened. In order to achieve improved storage of the rescue parachute, the container is pumped to be empty of air or virtually empty of air. A vacuum-pressure valve (15) is provided for this purpose. The cord of the rescue parachute is fastened by means of a strong shackle to a sufficiently dimensioned ring bolt (4) which is screwed to the container base and to the connection U-piece (11). The rip cord is fastened to an eye bolt (12) which is held in the quiescent position by a helical spring (9). Via a tilting lever (8), this eyebolt knocks a blade (6) into the compressed-gas cartridge (3). The housing cover (1), which is provided with a rubber seal, is held on the upper housing opening by the vacuum pressure. A filter is located between the rescue parachute and the release mechanism. <IMAGE>

Title: Hit indication for ball games
Inventor: GRUTESEN HANS-JOSEF
IPC: A63B71/06
Filed: 1988-12-01
Abstract: To achieve an accurate hit indication in ball games, the ball is provided with an electrically conductive surface. For this purpose, the ball is coated with a flexible metal layer or a conductor network or an electrically conductive plastic, or a conductor (wire) is incorporated into the surface covering, for example the layer of felt, of the ball. Two separate conductor tracks of metal or electrically conductive plastic, which engage in each other in a comb-like manner, are set into the permanently installed or transportable impact area - such as a court, boundary lines, out area and net. Upon contact of the conductive ball, these conductor tracks are electrically connected, and a circuit is thus closed. This signal is evaluated electronically by an amplifier circuit with connected storage circuit or by a computer with a corresponding program and indicated optically or acoustically, or the hits are automatically counted.

Title: Photosensitive composition
Inventor: HORIGUCHI RUMIKO
IPC: G03F7/004
Filed: 1988-12-09
Abstract: The invention relates to a photosensitive composition comprising an alkali-soluble resin and a compound which is sensitive to deep UV radiation, in particular the light having a wavelength of 248 nm emitted by a KrF excimer laser. The composition is suitable as a resist for the formation of fine, high-precision resist patterns. The invention furthermore relates to a silicon-containing photosensitive composition comprising a silicon-containing alkali-soluble resin and a silicon-containing photosensitive compound. A resist film produced from this silicon-containing photosensitive composition is highly photosensitive and is highly resistant to reactive ion etching with oxygen. In addition, it can be developed by means of alkaline solutions and consequently does not swell. This resist film is thus suitable for the production of the upper layer of a two-layered resist system.
