Patent DE-3304387-A1 (DE)
Title: Device for absorbing noises in cooling towers and large blowers
Inventor: ZOELLNER KURT
IPC: F28F25/00
Filed: 1983-02-09
Abstract: The absorption of the noise pollution from cooling towers and blowers is substantially improved by silencers which are arranged in the direction of propagation of the sound, or rather the air flow, and are assembled from individual silencer elements without being subjected to stress. In this arrangement, the silencer elements are preferably provided as elements whose longitudinal sides are produced from films. Such silencer elements produced from plastic films are protected both against contamination and against moisture and attack by bacteria, since they have a surface that is sealed on all sides. Surprisingly, they provide high absorption values, this being achieved by the particular construction of depressions and their arrangement. The individual films of the silencer elements are arranged pointing at one another, specifically at a distance from one another, the cavity additionally serving to absorb sound and, moreover, possibly being filled with sound-absorbing materials. It is possible to use such silencer elements to assemble silencers in practically any shape and size. <IMAGE>

Patent DE-3324959-A1 (DE)
Title: Receiving circuit for a space diversity method
Inventor: WERNER ERHARD DR
IPC: H04B7/08
Filed: 1983-07-11
Abstract: The invention relates to improving a space diversity method which, in particular, is used for receiving radio-frequency signals emitted by a wireless microphone. In deviation from the known prior art which disadvantageously needs two complete receiving circuits, the circuit according to the invention is characterised by the fact that the RF signals picked up by at least two antennas arranged at different locations are supplied via a change-over switch to only one main receiver circuit which contains the modules necessary for reproducing the information and that the change-over criterion is generated by brief interrogation via a changing-over of the main receiving circuit to the other antennas and by comparing the successively obtained stored reference voltages.
Patent DE-3326532-A1 (DE)
Inventor: KLEEBERG WOLFGANG DIPL CHEM DR
IPC: H01B3/40
Filed: 1983-07-22
Abstract: This application relates to methods for the manufacture of leakage current-proof epoxy-resin molded materials from epoxy resin mixture based on di- or polycarboxylic-acid glycidyl esters, di- or polyfunctional cycloaliphatic olefinic epoxides and dicarboxylic-acid anhydrides, carried out in such a manner that molded materials with good mechanical properties are obtained also for parts of large volume. For this purpose, the invention provides that, by means of the experimentally determined time necessary to reach the maximum temperature during the cross-linking of the epoxy resin mixture under quasi adiabatic conditions, the rate of cross-linking of the epoxy resin mixture is adjusted, by the addition of a diol or polyol, to at least as long as the time necessary to reach the maximum temperature during cross-linking of the glycidyl ester/dicarboxylic acid anhydride components.

Patent DE-3333463-A1 (DE)
Title: Multi-purpose cabinet
Inventor: KIEHN GUENTHER
IPC: A47B55/00
Filed: 1983-09-16
Abstract: In virtually all spheres of life, cabinets are required in order to be able to accommodate goods of the most varied type. In electrical engineering, both small cabinets, such as house connection boxes and small distributors are required and cabinet systems for medium and large distribution systems. The problem is now to develop a multi-purpose cabinet capable of combination with a minimum of designs, which cabinet offers a multiplicity of combination possibilities and, at the same time, considerably restricts the outlay for assembly means. The solution to the problem is seen in a multi-purpose cabinet which consists of two moulded parts, side walls (1, 2), the rear wall (3), the bottom plate (4) and the top plate (5) forming one moulded part and the door (6) forming the second moulded part. The side walls and possibly the bottom plate and top plate have partial surfaces (7) which run perpendicular to the rear wall and in which prepressed bores (8) are introduced in each case for receiving distancing adaptors (16) and/or twisting nipples and/or armoured thread screw connections. <IMAGE>
Patent DE-3335170-A1 (DE)
Title: Power amplifier for short electromagnetic waves
Inventor: MOLIERE THOMAS DIPL ING
IPC: H03F1/52
Filed: 1983-09-28
Abstract: Power amplifiers in semiconductor amplifier element construction, such as are used, in particular, as output stages for shortwave transmitters, require a control device for stabilising the temperature of the operating point in order to ensure the optimum intermodulation ratios are also achieved with full drive of the amplifier elements, independently of the operating temperature. As has been shown in practice, the temperature probes (TF) arranged at the semiconductor amplifier element housing can only incompletely detect the temperature changes actually occurring in the semiconductor in dependence on the drive, so that in the event of fast changes in the drive of such amplifier element units (EVS1, EVS2, ... EVSn), an unwanted displacement of the operating point occurs. It is proposed to considerably improve the temperature stabilisation of the operating point of such semiconductor amplifier elements by the fact that a further measurement variable derived by rectification of the RF output energy is superimposed on the electrical measurement variable supplied by the temperature probe, in such a manner that the aggregate measurement variable is also effective with increasing RF output energy in the direction of a temperature increase and conversely. <IMAGE>
Patent DE-3337725-A1 (DE)
Title: Process for producing wear zones, support regions or recesses in a sole or a foot bed
Inventor: BIRKENSTOCK KARL
IPC: A43B13/04
Filed: 1983-10-18
Abstract: The present invention "process for producing wear zones, support regions or recesses in a sole or a foot bed" relates to closed-cell, foamed products of this kind formed from a foam plastic material, especially by a blowing agent after opening the mould. These have a low weight and a fine and homogeneously formed pore structure, and are thus formed from a flexible material which can thus serve only inadequately as support for the foot. The material is additionally subject to high wear during use. According to the invention the foamed sole or the foot bed is heated at defined sections through the thickness of the material before or after the crosslinking, and compressed by a pressure treatment with permanent material compression and deformation to its intended shape and desired density, whereas the non-compressed part substantially retains its original material density and shape. Moulded-on material projections can in this way be pressed in whilst achieving the intended shaping to form regions with increased material density.

Patent DE-3345171-A1 (DE)
Title: Motor vehicle
Inventor: KIRCHWEGER KARL ING
IPC: B60K5/04
Filed: 1983-12-14
Abstract: In the case of a motor vehicle with a standard unit comprising an engine-transmission block, a vehicle axle and a subframe, which unit is held in the bodywork having an engine compartment cover, walls are fixed on the subframe covering this below and at the sides and the side walls, between which the engine is arranged, connected to the subframe preferably by way of rubber bearings, are connected to the body walls and extend the latter downwards. In this way, double walls are avoided and in addition the fixing of the walls on the subframe ensures that the walls do not have to be inserted between the body walls and the engine after mounting of the engine as has been the case hitherto, thereby essentially simplifying the assembly.
Patent DE-3345221-A1 (DE)
Title: Electrical conductor provided with an extruded conductive layer
Inventor: EL-AMIR KADRY DIPL ING

Filed: 1983-12-14
Abstract: The invention relates to an electrical conductor which is provided with an extruded conductive layer and consists of a plurality of conductive elements and in which tape lapping having conductive tapes is applied between the electrical conductor and the conductive layer. The invention is based on the object of designing the tape lapping for the electrical conductor at a low cost, such that it makes possible a conductive connection between the electrical conductor and the extruded conductive layer, with a small thickness and high compression strength. The object is achieved in that the tape lapping consists of a combination of conductive layers and insulating pressure-resistant tapes, the conductive layers being provided between two adjacent sections of insulating tapes in such a manner that they are arranged with a part of their width between the electrical conductor and one of the two adjacent insulating sections, and with another part between the other of the adjacent insulating sections and the extruded conductive layer. <IMAGE>

Patent DE-3402783-A1 (DE)
Title: Surveillance system, particularly a warning device triggered by the infrared radiation of persons entering into rooms to be monitored
Inventor: AKIYAMA SHOICHI
IPC: G08B13/19
Filed: 1984-01-27
Abstract: A surveillance system for detecting the presence of a person by utilising the infrared radiation emanating from it contains a detector which exhibits a number of concave reflector segments for generating separate fields of view. The infrared radiation emanating from the person who passes into any one of the fields of view is collected and focused onto a single sensor element for generating a warning signal. A plane mirror arrangement is provided in an optical reflection system of the detector for reflecting the radiation reflected onto the sensor element by the reflector segments, in order to reduce the space required for the optical system along the optical axis of the sensor element and thus to construct the detector to be space-saving. The optical system of the detector exhibits a device for optionally interrupting one or a number of beam paths between the relevant reflector segments and the sensor element so that the detector only receives the infrared radiation from the selected or desired fields of view. This makes it possible to adapt the field of view or the surveillance area of the detector in a very simple manner to the respective actual requirements.
