Title: Capacitor and method for its production
IPC: H01G4/08
Filed: 1987-10-09
Abstract: The invention relates to a capacitor (1) which is constructed from a plurality of electrically conductive and dielectric layers (2 and 3), a dielectric layer (4) in each case being arranged between two electrically conductive layers. The invention is based on the object of constructing such a capacitor (1) from layers which are as thin as possible. According to the invention, two successive electrically conductive layers (2 and 3) are in each case produced from two different materials. The dielectric layer (4) arranged between these electrically conductive layers (2 and 3) is produced from a material which is formed by an electrochemical or electrolytic conversion of the two materials which are used for the production of the electrically conductive layers (2 and 3). <IMAGE>

In order that the closure flap can be kept open and can nevertheless be pressed down again into as far as possible a clearly defined position in order to reclose the container, the handle is connected via a curved articulating member to the middle portion of the lid. The curved articulating member is preferably provided on the surface of the lid alongside the engaging means.
Patent DE-3840243-A1 (DE)
Title: Electromagnetic cable coupling, especially for towed bodies
Inventor: BORBERG HARTMUT DIPL ING
IPC: B64D3/00
Filed: 1988-11-29
Abstract: Until now, the coupling mechanism on the towed bodies has been operated with the aid of pyrotechnic means, that is to say, for example, a coupling bolt has been exploded in order to separate the cable from the towed body which process, however, is costly and, furthermore, not without danger. It is thus proposed no longer to accomplish the uncoupling of the towed body from the towing cable by pyrotechnic means, but to replace these means by a device using which the tensile force which acts in the towing cable and is introduced via the towing cable into the coupling body as an axial force can be converted into a transverse force which is less by a factor of 10-1000 than the axial force and can be applied by the electromagnet of the coupling as the actuating force which causes the uncoupling process.
