Title: Device for indicating the state of vehicle tyres
Inventor: RAUCH HANS DR
IPC: B60C11/24
Filed: 1982-10-02
Abstract: The invention shows the state of vehicle tyres, in particular the tyre pressure and the tread depth. For this purpose, speed-of-revolutions sensors (22 to 25) are arranged on the relevant wheels (10 to 13) and are connected a reference speed former (29) and comparators (32 to 35) for comparing the sensor signals with the reference speed. The reference speed former (29) is driven here by means of a logic element for detecting a predetermined vehicle state, namely forwards and/or non-braked straightline travel of the vehicle. The reference speed identified in the detected driving state is fed to a memory (31, 52) and compared with the sensor signals as a function of the respective travel speed (vF). As a result, both long-term changes of the tyre state (tyre wear) and short-term changes (pressure drop) can be detected (Fig. 2). <IMAGE>

Title: Method and device for making slotted grooves for drainage of traffic areas
Inventor: DERTNIG WOLFGANG
IPC: E01C11/22
Filed: 1982-11-23
Abstract: The method and the device described here serve for making slotted grooves for drainage of traffic areas and specifically on site and as it were continuously. To this end, a pipe string (19) is placed on a foundation (6) made from lean concrete and is then enclosed with concrete by means of a sliding form (9), either a slot reaching into the interior of the pipe string (19) and extending parallel to its longitudinal direction being milled in after setting and hardening of the concrete, or, if fine-grained material is used for the production of the concrete body, a joint plane being provided in the sliding form (9), which recesses in the formed concrete the necessary slot so that in future only the pipe string (19) has to be cut up and into with a milling tool. The production of a slotted groove for drainage of traffic areas according to this method is extremely economical in comparison with the measures used previously. <IMAGE>
Patent DE-3243901-A1 (DE)
Title: Pipe separator
Inventor: WEBER KLAUS
IPC: E03C1/10
Filed: 1982-11-26
Abstract: The invention relates to a pipe separator for installation in a pipe passage between a water supply point and a mixing device. To prevent any harmful mixture substances from being sucked out of the mixing device into the water pipe network when the water supply is shut off, a transfer pipe (13), which is connected to a piston (15) in a water pressure chamber (14), is mounted axially displaceably in the pipe separator. The water pressure chamber is connected to the water supply point. If the water supply is turned on, water flows into the water pressure chamber (14), with the result that the piston (15) and thus the transfer pipe (13) firmly connected thereto are axially displaced. The lower end of the transfer pipe (13) cooperates with a stop valve (7), which is open in the flow position of the pipe separator in order to free the pipe passage between water supply and mixing device. If the water supply is shut off, the piston (15) is drawn back, with support of a compression spring (16), owing to the resulting vacuum, with the result that the free end of the transfer pipe (13) is drawn out of the stop valve. The pipe passage between water supply point and mixing device is interrupted. <IMAGE>

Title: Flexible damping coupling
Inventor: SCHUHMANN BERND
IPC: F16D3/50
Filed: 1983-07-26
Abstract: The invention relates to a flexible damping coupling with compression springs which transmit the torque from one part of the coupling to the other. In order to construct a damping coupling of the said type in such a way that it is possible to achieve constant but, within limits, variable damping from coupling to coupling while, at the same time, keeping the structure comparatively simple and hence keeping down the outlay on assembly, it is proposed that the compression springs (7) be arranged radially and concentrically to the axis of the coupling in cylindrical recesses (10) in one part (1 or 2) of the coupling and that sliding pistons (6) supported under the spring load against surfaces arranged coaxially to the axis of the coupling on the other part (2 or 1) of the said coupling act in these recesses (10). <IMAGE>

Title: Method for the electrical excitation of gas lasers having at least two discharge paths, and a device for carrying out the method
Inventor: ELSNER JANOS
IPC: H01S3/097
Filed: 1984-01-16
Abstract: In the case of gas lasers having at least two discharge paths, it is particularly important to distribute the energy uniformly in time and space. In order to prevent resistive elements and the losses associated therewith, each discharge path is additionally supplied by a transformer and each of these transformers is energised by the same current. The energy supplied is consequently distributed uniformly in time and space, with purely inductive coupling and without resistive elements. As a consequence of this, the beam generation is improved and the electrical efficiency is considerably increased. A further advantage is that the individual supplies for the discharge parts are insulated from one another and are hence floating. This results in versatile possibilities for laser head design; earthing, interconnection, etc.

Title: Preparative separation of racemic mixtures into the antipodes by complexation gas chromatography on optically active metal coordination compounds
Inventor: SCHURIG VOLKER PROF DR
IPC: B01D53/02
Filed: 1984-03-23
Abstract: The present invention describes a method for the preparative separation of racemates (enantiomers, optical isomers, mirror-image isomers). The object is achieved by "complexation gas chromatography". This entails a chiral, non-racemic metal coordination compound being applied, either as solution in an involatile stationary phase (e.g. squalane, silicone oil) or as polymer, to an inactivated support (e.g. Chromosorb, kieselguhr), and packed into a gas chromatography column. Because of the enantiospecific interaction between racemic substrate and chiral stationary phase, preparative separation of racemates is possible in a gas chromatography procedure. The racemates which can be separated in this way comprise chemical compounds which are capable of coordination and which contain, in particular, oxygen, nitrogen and sulphur functionalities. Typical examples are: ketones, ethers, cyclic ethers, acetals, aziridines, thioethers. The method according to the invention is particularly used for racemates which have no suitable functionality for the conventional racemate resolution via diastereomers and which have not to date been amenable to racemate resolution by liquid chromatography. The method is used for racemate resolution of pheromones (e.g. chalcogran, brevicomin), fragrances, flavourings, chiral fine chemicals and chiral radiochemicals.

Title: Evaluation method for Doppler signal of magnetic proximity fuse for target detection and deep flying air target objects, involves detecting clutter-Doppler signal of received frequency or periodic time-spectrum
Inventor: BAUMER HANS
IPC: F42C13/04
Filed: 1984-04-17
Abstract: The evaluation method involves detecting clutter-Doppler signal of the received frequency or periodic time-spectrum. A predetermined tolerance excess change of the spectrum is interpreted as an echo signal reflected from the target. The compounding frequency or determined period spectrum is identified by comparing the frequency or period spectrum of the clutter-Doppler signal with the target echo and clutter-Doppler signal. An independent claim is also included for an arrangement for evaluating Doppler signal of magnetic proximity fuse for target detection and deep flying air target objects, which comprises a signal processing circuit and a target recognition unit.

Title: Process for producing a multiple-use copy for printed circuits, and appliance for implementing the process
Inventor: KELLER HANS
IPC: G03F9/00
Filed: 1984-05-10
Abstract: In the case of a process for producing a multiple-use copy, which accurately fits a drilled blank plate for generating a printed circuit, from a patterned film, a drilling pattern is compiled at the same time when drilling the blank plates and is provided with register holes and auxiliary gauge holes located in a defined position with respect thereto. The drilling pattern, which has been positioned with the aid of the auxiliary gauge holes and whose position has then been fixed, is used as an alignment pattern for the multiple-use copies placed thereupon, as a result of which the bores for the components are visually aligned with the soldering eyelets to an accuracy within tolerance. In order to fix the aligned position, the multiple-use copies have register holes punched into them, which are congruent with corresponding register holes of the drilling pattern and thus of the blank plates. Suitable appliances are described for carrying out the process.

Title: Circuit arrangement for current limiting in a DC/DC converter
Inventor: PROBST HARALD
IPC: H02M3/335
Filed: 1984-06-29
Abstract: A DC/DC converter having current limiting. The control variable for the current limiting is derived in the input circuit of the converter from the difference between the input pulse current (ie) and the input DC current (Ie). Since this difference is essentially proportional to the output DC current (Ia), this results in effective current limiting without direct measurement of the output current (Ia). This obviates costly output DC current measurement and the transmission of the measurement signal which generally requires DC isolation. <IMAGE>
