Title: Osmotic cyclic process
Inventor: HEITKAMP DIETER DR
IPC: F01K25/00
Filed: 1987-07-06
Abstract: An osmotic cyclic process suitable for energy recovery, in which solvent LM passes through a semi-permeable wall from a solution LK of relatively low concentration to a solution LA of relatively high concentration, can be operated with a relatively low volume of liquid in the pressure cell while maintaining its output for a relatively long time by virtue of the fact that, at the beginning of each cycle, there is in the higher-concentration solution LA precipitate B which goes into solution as the transfer of LM progresses, and that the regeneration (II) includes the recovery of the precipitate B, in particular by crystallisation due to relatively low solubility at relatively low temperatures TK, giving rise at the same time to a depletion of solution LK.

Title: Elastomer-coated shaped body for high dynamic stress - contg. small hard elastic bodies with high E-modulus distributed in rubber-elastic matrix
Inventor: ZEPPERNICK FRIEDRICH DR
IPC: B29D99/00
Filed: 1987-08-04
Abstract: In an elastomer-coated shaped body for high dynamic stress, the functional layer consists of a rubber-elastic matrix having low E-modulus of 0.1-1000 (1-100) N/sq.mm. Small hard elastic bodies equally large in each dimension, with a size of 0.9-20 (3-8) mm in the largest dimension, and E-molulus over 10000 (over 100000) n/sq.mm are strongly bonded, by chemical bonds, in the functional layer. USE/ADVANTAGE - The functional body is used esp. for elastomer-ocated rollers, full rubber tyres or wheels, caterpillar tyres or rims, resilient cushioning pts. or bridge supports. The dynamic E-molusus and the specific load/surface are increased. A higher squeezing efficiency of rollers can be achieved and higher pressure-pores can be transmitted.
Patent DE-3726411-A1 (DE)
Title: Fibre-optic magnetic field sensor
Inventor: BOSSELMANN THOMAS DR
IPC: G01R33/032
Filed: 1987-08-07
Abstract: The invention relates to a fibre-optic magnetic field sensor, in which a measurement is made of the magnetic field-dependent Faraday rotation of the plane of polarisation of a linearly polarised light beam (10, 11) which is propagated in an optical fibre (7). However, the Faraday rotation caused by the magnetic field has superimposed upon it linear and circular double-refraction properties of the optical fibre (7), which make more difficult the measurement of the Faraday rotation and, moreover, are still subject to environmental influences. According to the invention, an arrangement with heterodyne receiver and reciprocal light path is proposed, which permits measurement of the Faraday rotation without influence from linear double-refraction components of the optical fibre (7) and virtually without influence by circular double-refraction components of the optical fibre (7). Current sensors, magnetic field sensors. <IMAGE>

Patent DE-3735184-A1 (DE)
Title: Arrangement for controlling the gear change of a motor vehicle transmission
Inventor: STELTER NORBERT DIPL ING
IPC: B60W50/02
Filed: 1987-10-17
Abstract: A control for a semi-automatic transmission of a motor vehicle, in which the gear stages engaged are preselected by the driver, is equipped with a plausibility monitoring for the preselected gear stage; this prevents the acceptance of a gear stage which would lead to over-revving or stalling of the driving internal combustion engine. In certain driving conditions, it seems necessary, however, to suppress this plausibility monitoring. This is achieved in that a shift command transmitter is moved beyond the normal gear stage preselect position by increased operating force, so that the preselected gear stage is engaged, bypassing the plausibility monitoring.

Title: Method for displaying radar images
Inventor: PIEVERLING KLAUS VON DR ING
IPC: G01S13/86
Filed: 1988-02-09
Abstract: The radar image is displayed as a perspective image on a colour screen by the azimuth information from terrain points and moving targets being formed as x-axis information, and the elevation information of these terrain points and moving targets being formed as y-axis information. The range information on these terrain points and moving targets is converted into range-zone dependent colours. The brightness of the associated pixels is controlled analogously to the respective echo signal amplitude of the terrain points, while in contrast the echo signals from moving targets are displayed with constant brightness which contrasts with the brightness of the stationary terrain points and possibly also flashes. The method according to the invention is suitable for use in on-board radar in aircraft and in battlefield radar. The three-dimensionally scanning radar set can at the same time operate on the interferometer principle.

Patent DE-3821239-A1 (DE)
Inventor: FRANZ OTTO
IPC: G01M1/22
Filed: 1988-06-23
Abstract: The invention relates to a process for balancing rotating parts, in which compensation masses are arranged on the part to be balanced and in which the vibration acceleration of the rotating system formed by the rotating part and the compensation masses is measured and then integrated in order to obtain the vibration speed of the rotating system. A measure of the unbalance is obtained from the vibration speed in order to be able to monitor the unbalance during individual minimisation procedures in balancing. During a minimisation procedure, the size and/or the position in the rotating system of the individual compensation masses is altered, a further minimisation procedure being initiated as soon as the unbalance increases again during the current minimisation procedure. During a minimisation procedure, the maximum peak value of the vibration speed during a measuring time (Ti) is detected and stored. The peak value of the vibration speed during the current measuring time (Tn) is compared to the maximum peak value of the vibration speed of the immediately preceding measuring time (Tn-1). As soon as the instantaneous peak value of the vibration speed is greater than the stored maximum peak value of the vibration speed of the preceding measuring time (Tn-1), the next minimisation procedure is initiated.
Patent DE-3825843-A1 (DE)
Inventor: BROSIG STEFAN DIPL CHEM
IPC: G02F1/1339
Filed: 1988-07-29
Abstract: In a process for introducing distance elements (11) of a liquid crystall cell (1), the distance elements (11) are first dispersed in a liquid. The liquid is sprayed onto the substrate (2) of the liquid crystal cell (1). The vaporization process is so designed that the liquid droplets vaporize before reaching the substrate (2). To ensure rapid vaporization, the temperature of the liquid in the chamber of a spraying device is 20 DEG  above the boiling point TSO of the liquid at ambient atmospheric pressure. The substrate may also be heated to a temperature 20 DEG  above the boiling point TSO. The process is particularly suitable for introducing spherical distance elements (11) with a diameter less than 2 micrometres for liquid crystal displays.
