Title: Method of driving a multiplexible bistable liquid-crystal display
Inventor: AMSTUTZ HERMANN
IPC: G09F9/30
Filed: 1982-09-23
Abstract: In a method of driving a multiplexible bistable liquid-crystal display, a first operating voltage (V1), which is greater than a first limit voltage (Vg1) is applied to the selected display elements, and a second operating voltage (V2), which is less than a second limit voltage (Vg2), is applied to the nonselected display elements. At the first operating voltage (V1), only a first optical state (1) is stable, and at the second operating voltage (V2), only a second optical state (2) is stable. All the display elements are simultaneously caused to display by a single write voltage pulse. This achieves a high-contrast, steady and immediate display of the entire display surface. <IMAGE>

Title: Process and installation for enriching precious metals, heavy metals or heavy minerals in sand or gravel
IPC: B03B11/00
Filed: 1982-06-18
Abstract: Process and installation for enriching gold or other heavy metals and precious minerals occurring in freely distributed form in sand or gravel deposits, the material being divided by washing, shaking and sieving into an acceptably manageable, relatively large number of classified grain fractions and each fraction as a water-solids mixture being transformed into a broadly and uniformly flowing state. During the flowing state, the mixture is delayed by a plurality of transverse walls of a height between about 1/3 to 2/3 of the overall height of the fluidised bed and arranged one behind the other in the direction of flow, and is at the same time treated by suction and compression surges (pulsations), at amplitudes of up to about 15 mm and frequencies of up to about 3 Hz, introduced from below via flexible bottoms of the chambers formed between the transverse walls. The fine-grained waste fraction flowing off is after-treated at least to recover and recirculate mud-free water.

Patent DE-3306245-A1 (DE)
Title: Elastic bearing for building structures
Inventor: BATTERMANN WALTER
IPC: E04B1/36
Filed: 1983-02-23
Abstract: Elastic bearings for building structures in the form of resilient pads, blocks or similar elements made of rubber or rubber-like plastic require, for firm attachment to the connection part to be cushioned, a rigid, as a rule metallic supporting plate which is provided with the fastening means, such as for example studs, threaded inserts or the like. Frequently occurring disadvantages of these supporting plates are their susceptibility to corrosion and their low vibration damping. In contrast, the invention provides for such bearings a supporting plate of greater layer thickness and produced from a very hard and therefore practically undeformable rubber or plastic and thus creates an all-elastomer bearing which avoids the disadvantages of the known rubber-metal spring elements while retaining all of the desired elastic properties.

Title: Process for the liquid treatment of textile fibre material
Inventor: KARRER FRITZ
IPC: D06B5/22
Filed: 1983-06-21
Abstract: Textile fibre material is dyed particularly rapidly, uniformly and gently by evacuating it to dryness in a container, after which the dye liquor is introduced, avoiding an initial condensation in the fibre material, into the container. This is achieved by introducing the dye liquor at a low temperature coordinated with the vacuum, or preheating the fibre material to the necessary extent. After introducing the dye liquor, this is placed under a slight excess pressure and made to act on the fibre material, which is then dried in the container.
Patent DE-3323131-A1 (DE)
Inventor: LINK HELMUT D
IPC: A61F2/30
Filed: 1983-06-27
Abstract: A hip joint endoprosthesis has a downward tapering stem (1) which is to be anchored in the femur and is composed of a main part (7) connected to the condyle head (4) and of a plurality of wedge pieces (10) which are movably guided longitudinally along the main part by means of cooperating guide surfaces (11,12). The friction on the guide surfaces between the main part (7) and the wedge pieces (10) is smaller than the friction caused by the outer surface (13), formed for promoting adhesion, of wedge pieces (10) on the bone. When the medullary cavity receiving the prosthesis stem widens, the load on the main part (7) causes an expansion of the wedge pieces (10) and hence an adaptation of the shape of the prosthesis.

Title: Pulse-controlled lifting-magnet drives
Inventor: LUNGU CORNELIUS DIPL ING
IPC: H01F7/16
Filed: 1983-06-29
Abstract: Pulse-controlled lifting magnet drives. These drives represent an optimised combination of a lifting magnet and a permanent-magnet retaining device. In the event of rectified polarisation of the coil 1 and of the permanent magnet 4 by powerful pulses, the magnet armature 3 is attracted. In the attracted state, said magnet armature 3 is fixed by the magnetic field of the permanent magnet 4. The magnetic field lines run through two axial air gaps a' and b' which are arranged in series, which increases the retaining force. The magnet armature 3 is released under the influence of an external force by weak pulses in the opposite direction. In the event of short switching characters, forces can be achieved which are 50 times greater than the intrinsic weight of the device for stroke lengths which reach half the drive lengths. In this case, material savings which make the additional costs for the necessary pulse units competitive can be obtained with a simple construction. <IMAGE>

Title: Brake pressure control unit
Inventor: REINARTZ HANS-DIETER
IPC: B60T8/30
Filed: 1983-12-02
Abstract: A brake pressure control unit for a pressure medium operated dual circuit vehicle brake system is proposed, in which the control valves (7, 8) of each brake circuit (I, II) lie in series in a housing (1) and in which the control pistons (14, 14') of the control valves (7, 8) can be displaced in opposition to one another into the closed position as a function of the pressure. The two control pistons (14, 14') are acted upon by a common control spring (10) and the mutual spacing of the valve seats (20, 20') assigned to the control pistons (14, 14') can be varied. In the event of a variation of the mutual spacing of the valve seats a uniform variation in the reversing pressure is achieved by very simple means in both brake circuits (I, II) by the control spring (10) common to the two control pistons (14, 14') and the uniformity of the brake pressure build-up during the pressure-reducing phase is improved. <IMAGE>

Patent DE-3421213-A1 (DE)
Title: Two-channel/two-frequency laser interferometer
Inventor: SCHUESSLER HANS-H DR ING
IPC: G01B9/02
Filed: 1984-06-07
Abstract: The invention relates to a two-channel/two frequency laser interferometer, in which the emitted light beam is firstly split uniformly into two beam corridors situated next to one another in parallel. Inside these two beam corridors, the light is then divided in each case into its two beam components of different frequency, and the reference beam component thereof is retroreflected into the receivers of the laser head. Only the measuring beam component is passed in the measurement section, which can be of various lengths, and is retroreflected by measuring reflectors at the end thereof, interference taking place with the reference beam. In order to simplify the computational outlay in the signal evaluation, it is proposed to construct or arrange the polarisation beam splitters for the beam splitting in such a way that beam components of different frequency in the two beam corridors enter the measurement section. As a result, it is possible by simple subtraction of the two interference signals to obtain an aggregate signal for double the mean value of the length of the measurement section on the two beam corridors.
