Title: Cover for roofrack
Inventor: BEHNK HOLGER
IPC: B60R9/055
Filed: 1981-09-08
Abstract: The invention relates to a cover for the roofracks of cars, especially cars to tow caravans. It is composed of a covering hood (10, 10a, 10b, 40, 45) which can be placed on the roofrack (5) and is pivotable about a joint (21), which is arranged on the front end section (8) of the roofrack (5), in such a way that the rear section (12) of the covering hood (10, 10a, 10b, 40, 45) is raised with respect to its front section (11). The covering hood (10, 10a, 10b) takes the form of a shell-like hollow body (39) which decreases in thickness (51) from the rear section (12) to the front section (11). The rear section (12) of the hollow body (39) may take the form of a spoiler (13). A supporting device (43, 43a, 43b, 48) is provided for connecting the rear section (12) to the rear end section (9) of the roofrack (5). The roofrack cover according to the invention reduces the occurrence of travelling wind noise due to air turbulence around the roofrack (5) and reduces the air resistance of the vehicle and/or the vehicle and trailer. <IMAGE>

Title: Cable having reinforcing elements, especially an optical cable
Inventor: HAAG HELMUT DIPL PHYS
IPC: G02B6/44
Filed: 1981-10-01
Abstract: The invention relates to an optical cable having at least one optical waveguide and longitudinally running reinforcing elements which are twisted around the cable axis. In order to achieve the object of creating reinforcement which is as free of torsion as possible, which does not exacerbate the manufacture especially of an optical cable and permits light cables with a small diameter it is proposed that the reinforcing elements consist of a plurality of individual elements twisted in the opposite direction to the cable twist of the reinforcing elements, and that the sections of the individual elements which are located radially outside run approximately parallel to the cable axis.
Patent DE-3145698-A1 (DE)
Title: Apparatus for producing components from fibre-reinforced materials
Inventor: VOGEL RICHARD ING GRAD
IPC: B29C43/56
Filed: 1981-11-19
Abstract: The invention relates to an apparatus for producing components from fibre-reinforced materials, for example glass-fibre laminates or components from other materials, which are adhesively bonded under a vacuum, cured and subjected to pressure in similar production processes. The apparatus comprises a compression mould (1) having a mould body (3) adapted to the component (4, 5) to be produced. The fibre-reinforced material for the component is laid onto the mould body (3); a membrane (6), for example of silicone rubber, adapted in the mould to the component, is slipped over this arrangement. The membrane overlaps the fibre-reinforced material for the component. In this marginal region (7), the membrane is provided with a peripheral sealing profile (8), which engages in a correspondingly shaped profile seat (9) within the compression mould (1). As a result, the space between membrane, compression mould and fibre-reinforced material is sealed off gas-tightly from the outside. By means of a vacuum connection (10) of the membrane, a negative pressure can then be generated in this space, by which pressure the material for the component is compressed. To improve the gas-tight seating of the membrane in the region of the sealing lip (8), a further vacuum connection (11, 12) may be provided, by means of which a negative pressure is generated in the hollow space between sealing lip (8) and the bottom of the profile seat (9), by which pressure the sealing lip is sucked firmly into the profile seat. The advantage of such an arrangement is that the membrane (6) can be used repeatedly; in this way, 50 or more components can be produced with one membrane. <IMAGE>

Title: Heat exchanger
IPC: F28D7/02
Filed: 1981-11-24
Abstract: The heat exchanger consists of a primary circuit having ribbed tubing which is helically wound in the form of a screw and has an intake and an outlet, a housing accommodating the tube helix and made from two concentric tubes having sealing covers on the end faces for the inlets and outlets of the carrier media, and a secondary circuit having a flow channel formed by a partition strip that is helically wound in the form of a screw in a manner coaxial with the tube helix, the width of the partition strip corresponding approximately to the cylindrical annular gap between the tubes and the partition helix being screwed into the tube helix. This results in a design for a heat exchanger that is particularly favourable from the point of view both of heat engineering and of production and assembly engineering.

Title: Flexible endless test tube connector with arbitrary separating possibilities
Inventor: STIMPFIG JOERG
IPC: B01L3/00
Filed: 1982-05-11
Abstract: The flexible endless test tube connector has a perforation for the purpose of separation, for cost-effective reduction of the time spent on processing of laboratory reagents, especially of radioimmuno-assays, for facilitating automation of radioimmunoassays and for saving of expensive equipment in laboratories. The perforation permits separation of any number of test tubes and hence economical use of material. The test tube connector can be produced in a particularly cost-effective way, so that the final product becomes more expensive only by fractions of a percentage.

Title: Semiconductor components and process for producing them
Inventor: ADLERSTEIN MICHAEL G
IPC: H01L21/78
Filed: 1982-11-23
Abstract: A multiplicity of microwave semiconductor components can be produced by coating a surface of a semiconductor material body with a thin heat dissipation layer, then masking certain areas of the heat sink layer and coating the unmasked areas of the heat sink layer to form a carrier layer. Extensive parts of the semiconductor material body are then removed, thereby producing a multiplicity of mesa-structured diodes, at least one of which is in each case situated in that part of the semiconductor material body which is associated in each case with a masked area of the heat sink layer. Consequently, each mesa-structured diode has, or groups of mesa-structured diodes have in each case, a thin heat sink layer on one side, the mesa-structured diodes being mounted on a carrier layer to enable them to be handled subsequently. There are electrodes on the mesa-structured diodes to produce the connections. The individual diodes or diode groups are then separated from the carrier layer so that individual diodes or individual groups of diodes are obtained.

Title: Method and device for representing signal information provided in polar coordinates
Inventor: BIRK ADALBERT DIPL ING
IPC: G01S7/531
Filed: 1982-12-23
Abstract: It is particularly in the case of ultrasonic echo signals, which were obtained by means of a sector scan process and must be temporarily stored for being displayed in accordance with a television standard, that the problem exists that the echo information provided as vectors in a scan direction must be transferred in a suitable manner into cartesian memory matrixes. In this connection, it is appropriate to carry out a data reduction for the purpose of digital storage. According to the invention, all data acquired from the signal information are then temporarily stored in a vector memory, and from the vector memory the data are transferred into a cartesian memory matrix, the required data reduction only being carried out when the information is transferred into the memory matrix. <IMAGE>

Title: Method of testing pipes or pipe networks for leakage
Inventor: MERTENS PETER DIPL PHYS DR RER
IPC: G01M3/28
Filed: 1983-05-07
Abstract: A method of testing pipes or pipe networks for leakage is specified in which the leakage test is effected by means of pressurised fluid by determining changes in pressure. To improve the leakage test by eliminating temperature-induced pressure change, the fluid pressure in the pipes, pipe networks or pipe sections thereof is set to at least two different pressure levels as an initial pressure in each case for determining at least one pressure change. A pressure-change difference standardised in terms of time is formed from the pressure changes standardised in terms of time and belonging to the different initial pressures and is compared with a preset value related to the time unit. Leakage is deduced if the pressure-change difference is greater than the preset value.
