Patent DE-3836981-A1 (DE)
Title: Pressure sensor, especially tyre pressure sensor for motor vehicles
Inventor: SCHMID GUENTER DIPL ING
IPC: B60C23/04
Filed: 1988-10-31
Abstract: A pressure sensor (10) is proposed, especially a tyre pressure sensor for motor vehicles, which is to be fastened to the periphery of a wheel rim and has a switching element to be pressurised with air pressure and arranged in a reference pressure chamber (11). In order to be able to monitor a plurality of threshold values of the tyre pressure by means of a cost-effectively producible tyre pressure sensor, it is proposed to arrange a plurality of reference pressure chambers (11, 11a, 11b) within each other. The respective diaphragms (13, 17, 22) of the reference pressure chambers (11, 11a, 11b) are oriented to the effective pressure. On the respective inner sides of the diaphragms (13, 17, 22), contacts (18, 23, 25) are arranged, which interact with counter contacts (19, 24, 26) arranged on the upper side of the diaphragm (17, 22) lying thereunder or of the bottom plate (14). Electrical contacts (18, 23, 25) and counter contacts (19, 24, 26) are arranged with respect to each other on the same axis. A plurality of air pressures can be detected in a common pressure housing with a relatively good measuring sensitivity. <IMAGE>

Title: Device for printed circuit board retention
Inventor: FEUERLEIN FRIEDRICH
IPC: H05K7/14
Filed: 1988-11-12
Abstract: It is intended to create a device for printed circuit board retention for electronic apparatuses having a high packing density, which device grips the entire printed circuit board arrangement starting from the side walls of the apparatus chassis, can easily be installed, and permits rapid access for replacement of printed circuit boards. Retaining elements (4) which are provided with latching hooks (40) are inserted into corresponding apertures (120) in the side walls (12) and, by means of a retaining groove (41) constructed on them, allow the fastening of a motherboard (3), which is fitted with further printed circuit boards (91). By means of a shaft bearing which is constructed on the retaining element (4), it is furthermore possible to insert a hinged shaft (92) to which retaining bars (5) are fastened such that they can pivot, which, for their part, lock the plugged-on printed circuit boards (91). The invention can be used generally for relatively large electronic apparatuses, especially for built-in apparatuses (flush-mounted apparatuses). <IMAGE>

Patent DE-3901101-A1 (DE)
Title: Device for reproducing colour television signals
Inventor: FRANCKE ERWIN ING GRAD
IPC: H04N15/00
Filed: 1989-01-16
Abstract: To create a colour picture reproduction device of small construction and having a high picture resolution, it is proposed to use three monochromatic picture tubes which are arranged parallel to one another in a common plane. The picture tubes are supplied with the red, green and blue separations of the colour television signal to be reproduced. The monochromatic images reproduced on the screens are reflected "on the backs" of the picture tubes and combined to form the colour picture in an additive colour mixer mounted above the picture tubes. The colour picture is then distributed to the two oculars of viewing optics by means of a beam divider. Since the resolution of monochromatic picture tubes is much better than that of colour picture tubes, the picture resolution of the colour picture thus generated is increased correspondingly compared with a reproduction on a dot matrix tube (Fig. 1). <IMAGE>
Patent DE-3902929-A1 (DE)
Title: Feeding apparatus, in particular for wood disintegrators
IPC: B26D7/06
Filed: 1989-02-01
Abstract: An advancing/reversing drive for a drawer in wood choppers which consists of pressing plate (13), side faces (12) and rear wall (14), is formed by drive motor (20), chain (19) and chain wheel (18) which acts on a drive spindle (16). On the latter (16) there runs an advancing nut (21, 21a, 21b) which transmits the advancing force (P) to the drawer rear wall via a strong compression spring (22). The spring (22) thus acts simultaneously as shock absorber for the driving and advancing elements. <IMAGE>

Title: Method and device for conditioning agricultural cuttings, in particular mown grass, for feed purposes
Inventor: GRUBE GUENTER
IPC: A01D82/00
Filed: 1989-02-25
Abstract: The invention relates to a method for conditioning (stalk) cuttings for feed purposes, in which the stalks are picked up after being cut and are then conditioned by tearing and/or beating in such a way that they are (only) partially opened, so that although the outer wax layer is broken open, the basic geometric stalk construction is essentially retained, while the cells providing for the strength of the stalks are essentially destroyed; and to a device suitable for this purpose, with a pick-up rotor for picking up the cuttings and a downstream conditioning rotor with profiled strike edges for conditioning the cuttings, and with a stationary strike rail profiled corresponding to the strike edges of the conditioning rotor, the strike edges of the conditioning rotor having essentially triangular projections arranged alongside one another and meshing with the correspondingly formed projections, whose radial spacing from the conditioning rotor is adjustable, and the points of the projections of the strike edges (plates) of the conditioning rotor and those of the strike rail are broken; and the stationary strike rail is held immovably on the support construction of the device (Fig. 1). <IMAGE>
Patent DE-3909467-A1 (DE)
Title: Golf course
Inventor: HUG WILLI H
IPC: A63B69/36
Filed: 1989-03-22
Abstract: The application relates to a golf course. It is based on a golf course with a plurality of holes for holing the ball, a plurality of teeing grounds being arranged around a central region, from which teeing grounds the ball is in each case driven outwards and, from different teeing grounds, in different, substantially radial directions. The object is, while substantially restricting the use of land as compared with conventional golf courses, nevertheless to allow golf to be played with conventional clubs and balls and without any restrictions. This object is achieved, in the case of a golf course according to the invention, in that the number of teeing grounds corresponds to the number of holes to be played to, in that fairways extend substantially in a star pattern from the central region, in that the holes are arranged substantially radially outside the central region at a long distance therefrom and close to the outer end of the fairways, and in that substantially radially extending return paths to the central region are arranged between fairways and protected from the latter.

Title: Process for the preparation of a gas adsorbent
Inventor: SUGO TAKANOBU
IPC: B01J47/12
Filed: 1989-04-04
Abstract: In the process for the preparation of an adsorbent which is capable of effectively removing substances which emit an odour, and in particular foul-smelling substances, the adsorbent is obtained by exposing an organic compound of high molecular weight, such as, for example, polyolefinic polymers or halogenated polyolefinic polymers, to ionising radiation, and then graft-polymerising the compound of high molecular weight with a polymerisable monomer containing ion exchange groups, and/or with a polymerisable monomer which can be converted into ion exchange groups, in order to incorporate the ion exchange groups into the compound of high molecular weight.
