Patent DE-3811623-A1 (DE)
Title: Movement aid for bath tub and seating furniture
Inventor: WEDEMEYER ERWIN
IPC: A61G5/14
Filed: 1988-04-07
Abstract: Movement aids are devices for disabled or frail people which assist them in sitting down, lying down, sitting up or getting up or enable them to do these. This movement aid comprises a foldable frame with three plates which are connected in joints and form a Z and between which there are two two-cell bellows arranged opposite each other. They are operated by water or compressed air and cause a supplementary lifting movement to the seat plate. Control of these processes takes place via control valves or switches for the compressor. The movement aid has a very flat, simple design due to the foldable frame and the bellows. If required, it can be taken along and used on journeys. For use in an arm-chair as a movement aid assisting in rising or sitting down, the special feature resides in the fact that the control system causes the front bellows to fill first in order to support the knee joints and then the rear bellows to lift the main weight of the body out of the arm-chair.

Title: Apparatus for separating off solids from liquids
Inventor: KOLLER JOSEF DIPL ING
IPC: B01D29/35
Filed: 1988-08-30
Abstract: The invention relates to an apparatus for separating off solids from liquids, in particular from cooling water. The apparatus comprises a rotationally symmetrical screen 1 and a suction apparatus 4 arranged on the intake side and a scraper 5 arranged on the outlet side, to clean the screen 1, the shut-off valve 8 being opened and the drive 3 setting in rotation the suction apparatus 4 and scraper 5. The resulting vacuum in the dirt discharge tube 7 effects a backwashing of the screen 1 at the suction slot 9. For most types of fouling, this backwashing is sufficient, but not for fibrous fouling which in many cases leads to entangling on the outlet side of the screen 1. In these cases, the scraper 5 has the task of scraping off or shearing off the fibrous fouling, the detached fouling being taken up by the backwash and extracted by the suction apparatus 4. <IMAGE>
Patent DE-3831274-A1 (DE)
Inventor: OIKAWA RYUETSU
IPC: B29C37/00
Filed: 1988-09-14
Abstract: An injection molded angle product comprises a groove 30 formed along the inner edge portion between the two walls 10, 20. The shape of the groove 30 is preferably U-shaped in cross-sectional, the width and depth of the U-shaped groove being 30 to 60% of the wall thickness of the angle product. The groove 30 is formed during the moulding process, its purpose being to allow the material in the edge region R to cool more rapidly than the material of the walls 10, 20 when the moulded article is removed from the mould. This prevents the angle formed between the walls 10, 20 during moulding from getting smaller during such cooling. Reinforcing ribs 40 may be provided across the groove. <IMAGE>

Title: Rotary hoop-knife splitting machine
Inventor: TRUETSCHEL WILLI
IPC: C14B1/18
Filed: 1988-09-16
Abstract: In a rotary hoop-knife splitting machine (1), there is a programme-control device which, during the passage of the splitting material, lowers the articulated roller (15) out of a lower basic height and/or the gauging roller (13) out of an upper basic height. This allows even greater accuracy during the production of the grain-split material, so that the waste during further processing is low. <IMAGE>
Patent DE-3834738-A1 (DE)
Inventor: SCHWARTE STEPHAN
IPC: C08F265/02
Filed: 1988-10-12
Abstract: PCT No. PCT/EP89/01126 Sec. 371 Date May 3, 1991 Sec. 102(e) Date May 3, 1991 PCT Filed Sep. 26, 1989 PCT Pub. No. WO90/03851 PCT Pub. Date Apr. 19, 1990.The invention relates to a process for the preparation of a multicoat coating which uses an aqueous, clear topcoat composition containing a polyacrylate resin as binder. The polyacrylate resin can be obtained by adding an ethylenically unsaturated monomer (a1) which contains carboxyl groups, and a mixture (b) consisting of (meth)acrylic esters which are free from carboxyl groups and of ethylenically unsaturated monomers which contain hydroxyl groups, to an organic solvent or mixture of solvents either successively or alternately in part amounts and polymerizing the mixture in the presence of a radical-forming initiator, neutralizing the resultant polyacrylate resin after termination of the polymerization and dispersing it in water. The type and amount of (a1) and (b) are chosen such that the polyacrylate resin has a hydroxyl value of 40 to 200, an acid value of 20 to 100 and a glass transition temperature (TG) of -40 DEG  C. to 60 DEG  C.
Patent DE-3834869-A1 (DE)
Title: Method for the speech-dependent identification of individuals
Inventor: ZINKE JOACHIM DIPL ING
IPC: G10L15/14
Filed: 1988-10-13
Abstract: By establishing a correspondence of an analysed pattern of words actually spoken in with reference patterns which have been analysed in a speaker-dependent way and stored, it is intended for it to be possible for an individual to be unequivocally recognized, without further operating procedures, apart from the speech to be entered, being necessary. A sequence of words to be entered as speech by the individual to be recognized, and characterising the identity, is analysed by a speech analysis device and offered to a first comparator for speaker-independent recognition. From the sequence of words recognized in a speaker-independent manner, an address is formed with which a storage region in a speaker store, assigned to the respective person, is controlled, so that a speaker-dependent recognition can be carried out. This is carried out by means of a second comparator which establishes whether a correspondence exists between the reference patterns of the words actually spoken in and the content of the associated storage region. By this means, the identity of the individual concerned is unequivocally recognized. In the next successive speaker-independent recognition, the storage region responsible for the speaker-dependent recognition is addressed directly, so that a relatively rapid recognition is possible with a simple mode of operation, additional commands being, furthermore, able to be input individually later.

Title: Electrically triggerable, hydraulic pressure control valve
Inventor: HONIG ERNST-AUGUST DIPL ING
IPC: F16H61/08
Filed: 1988-10-28
Abstract: An electrically triggerable hydraulic pressure control valve (1) for the controllable pressure medium actuation of a gearshift element (2) of a motor vehicle automatic transmission by means of a control piston (5) is described which, under the influence of a control pressure, acting counter to a return force and infinitely adjustable by a solenoid valve (15), triggerable as a function of the operating condition, controls the actuation pressure prevailing in a pressure actuation line (4) leading to the gearshift element (2) by connecting the pressure actuation line (4) to a pressure medium feed line (3) or to an outlet line (22) as a function of the position, it being possible to apply a pressure derived from the actuation pressure to one active face of the control piston (5). In the said pressure control valve, it is proposed that, with the current applied to the solenoid valve (15) switched off, the control piston (5) be in a position connecting the pressure actuation line (4) to the pressure medium feed line (3) and that it be possible to feed the pressure derived from the actuation pressure to the control pressure chamber (16) connected to the solenoid valve (15) in order to form the control pressure, so as to ensure an infinitely variable adjustment of the actuating pressure of the gearshift element. <IMAGE>

Title: Apparatus for drawing an optical waveguide
Inventor: SCHNEIDER SIGRUN DIPL ING
IPC: C03B37/027
Filed: 1989-03-30
Abstract: In the production of an optical waveguide (2) from a preform (3) in a drawing furnace (1), the optical waveguide must be cooled so that it can be further processed, for example coated. It is known to cool the optical waveguide (2) by a gas. The gas surrounding the optical waveguide (2) forms a boundary layer thereon which prevents its cooling and can be stripped off by at least one gas flowing in at an angle. n gas inlets (6, 7, 8, ...) are therefore installed along and around the optical waveguide (2) between the drawing furnace (1) and the cooling device (4), from which a plurality, at most n, gases flow out. The gas flowing out of the nth gas inlet (6, 7, 8, ...) strips off the boundary layer formed by the gas coming from the (n-1)th gas inlet. <IMAGE>
