Patent DE-3113334-A1 (DE)
Title: Method for producing multilayer printed-circuit boards
Inventor: MERKENSCHLAGER HANS-HERMANN DI
IPC: H05K3/46
Filed: 1981-04-02
Abstract: The invention relates to a method for producing multilayer printed-circuit boards by hot compression of a plurality of etched inner layers which are insulated from one another by adhesive films. During the compression of a plurality of inner layers which are separated by means of insulation films, air enclosures cannot be completely avoided. After the incorporation of holes, and their through-plating, these air enclosures lead to insulation defects. In order to reduce the influence of such air bubbles on the insulation level, the etched inner layers are coated, before compression, with a low-viscosity solution of that resin (or a compatible resin) from which the carrier board is made, as a result of which an additional insulation layer is produced between the holes and the copper-conductor layer. The method according to the invention is particularly suitable for the production of highly miniaturised multilayer printed-circuit boards for use in data technology. <IMAGE>
Patent DE-3115446-A1 (DE)
Title: Circuit arrangement for electrical components of a motor vehicle
Inventor: DEICKE AXEL DIPL ING
IPC: B60Q1/26
Filed: 1981-04-16
Abstract: A circuit arrangement for electrical components of a motor vehicle whose circuits can be switched on before the vehicle engine starts and which contain a timing element which determines the switch-on duration and is switched off before its expiry during or directly after the starting of the vehicle engine, contains a switching element which responds to the ripple of the supply voltage in the circuit of the component itself and switches off the timing element prematurely. As a result, intervention in other circuits which change their conductive state when the motor vehicle starts is dispensed with.
Patent DE-3119692-A1 (DE)
Title: Structural element which can be prefabricated
Inventor: CARL HEINZ ING GRAD
IPC: E06B9/17
Filed: 1981-05-18
Abstract: The invention relates to a structural element which can be prefabricated and is intended for a window or a door with a roller blind. Said structural element can be introduced into a window opening and forms a surround for a frame. A known structural element has a surround which is screwed together using plate-edge profiles and extruded profiles and the upper transverse member of which is formed by the side walls of a roller-blind casing. Said structural element is introduced into a correspondingly dimensioned wall opening and is sealed and fastened therein in a conventional manner. The production of the known structural element is expensive. In addition, cold bridges are unavoidable. It is also a disadvantage that the wall opening has to be matched precisely in each case to the structural-element size which varies in dependence on the window size. The invention provides a structural element which, as a surround, is a shaped concrete element in which the roller-blind casing on the outer side of the frame can be fixed and, in addition, heat-insulating elements are provided in the contact regions between the shaped element and the frame or the roller-blind casing. It is of advantage that the shaped element can be prefabricated from concrete inexpensively. The fastening and arrangement of the frame and of the roller-blind casing avoid cold bridges. A basic size of a structural element can be used for differently sized windows or doors by varying the opening size for the frame. The wall openings to be provided for this purpose can then have a uniform size, although the windows or doors are of different sizes.

Title: Device for the continuous treatment of a web material in a cold plasma
Inventor: IMADA KIYOSHI
IPC: B29C71/04
Filed: 1981-06-19
Abstract: The device for the continuous treatment of web material in cold plasma comprises a plasma chamber upstream of which is connected a front pre-vacuum chamber and downstream of which is connected a rear pre-vacuum chamber, these pre-vacuum chambers serving for the leading in of the web material into the plasma chamber and the leading out of the web material out of the plasma chamber without air being thereby able to pass from the surrounding atmosphere into the plasma chamber. In the plasma chamber itself, the cold plasma is generated between a rotatable cathode drum and a plurality of rod-shaped anodes arranged around the cathode drum by the application of high-frequency electrical power. The web material is guided in direct contact with the cathode drum in the interspace between the cathode and the anodes with the aid of guide rolls which guide the web material onto the rotating cathode and remove it from the latter. The electrodes and the guide rolls are together mounted or supported cantilevered on one and the same lateral wall of the plasma chamber, the lateral wall bearing the electrodes and the guide rolls being designed so as to be removable and re-installable rotated through 180 DEG  with respect to the horizontal. The opposite lateral wall of the plasma chamber is designed as a removable cowl for the plasma chamber. By means of this removable cowl, the plasma chamber is readily accessible for maintenance and cleaning purposes.

Title: Full-lining disc brake
Inventor: REINECKE ERICH ING GRAD
IPC: F16D55/10
Filed: 1981-11-19
Abstract: Brake discs in full-lining disc brakes, which are manufactured from U-profiles, may deform (bend apart) due to high contact pressures. As a result, the brake linings are pressed against brake discs of varying curvature, leading to high wear of the linings. According to the invention, the brake lining carriers are provided with cut-outs, with the result that, due to the elasticity of the lining carriers thereby achieved, the brake linings, which consist of segments, can follow the obliquity which has arisen due to the deformation of the brake discs and the linings assume a largely planar position.
