Title: Membrane for sound converters (transducers)
Inventor: THIEL BERNHARD
IPC: C04B35/111
Filed: 1985-11-29
Abstract: The known membranes consist of pasteboard or of plastic. These can be manufactured inexpensively and have high internal damping but tend to troublesome partial vibrations in the audible range. Membranes made of metal are expensive; because of their high strength the partial vibrations are admittedly higher but because of the lower internal damping of the metal they are very obtrusive. The proposed membrane (1) consists of corundum which is formed of pure aluminium, which has been brought to the desired shape, by anodic oxidation and subsequent firing at temperatures above 600 DEG C. The method of manufacture of the membrane consisting of corundum is simple and inexpensive and the product is superior to the known membranes in respect of its acoustic properties (partial vibrations, distortion, pulse characteristics). <IMAGE>

Title: Method of fabricating a lead rechargeable battery having a gel electrolyte
Inventor: SALAMON KLAUS DIPL PHYS DR
IPC: H01M10/10
Filed: 1986-02-03
Abstract: Additional reinforcement of an acid electrolyte fixed with a gelatiniser to protect it against shrinkage cracks is possible with the aid of an acid- and oxidation-resistant fibrous material by first producing a homogeneous sulphuric acid/fibre mixture, adding colloidally dissolved or colloidally dispersed silica to the latter while continuing to stir and then pouring this mixture while still in the sol state into the rechargeable battery where it gels. The gelling process starts approximately 10 minutes after adding the silica, with the result that the pouring operation has to be completed by this point in time. Apart from glass, suitable fibrous materials are various plastics such as polyester, polyethylene, polypropylene or polyolefins, fibre lengths around 1 mm and fibre thicknesses between 0.5 and 20  mu m being particularly advantageous.

Title: Circuit carrier for an electronic circuit
Inventor: SAITO MASAHIKO
IPC: H05K9/00
Filed: 1986-02-14
Abstract: In the case of a circuit carrier, two circuit boards are provided which are arranged with their rear sides opposite one another. Located on the front of one board are two circuit elements which are intended to be screened from one another in order that there is no capacitive and/or inductive coupling between the circuit elements. An earthing metal plate is located between the two boards. A screening metal plate projects approximately at right angles from this earthing metal plate. This screening metal plate, which is constructed integrally with the earthing metal plate, is located between the two circuit elements which are to be screened from one another, as a result of which any capacitive and/or inductive coupling between these circuit elements is overcome.

Title: Device for sealing rotary tubular kilns (furnaces) with respect to fixed housings
Inventor: SANGERHAUS WOLFGANG
IPC: F27B7/24
Filed: 1987-12-31
Abstract: The invention relates to a device for sealing rotary tubular kilns with respect to fixed housings by means of radial sliding surfaces on a fixed sliding ring and on a radially and axially movable, revolving wear ring. A supporting ring was unified in such a way that it fulfils, as a core piece of the seal, all of the functionally important tasks. This ring is axially movable by means of a plurality of articulated bows and is prestressed by means of a plurality of tension springs, as well as additionally connected to the revolving drum via tangential tension rods. An annular groove provided in the supporting ring serves to receive a two-piece wear ring. The packing is wound round as a band and forcibly deformed into a single-wave extension compensator. A spring element provided in the wave trough ensures the dimensional stability of the extension wave which is drawn in with respect to the drum axis. By means of a scraper and an opening in the fixed housing, in the region of the seal the interspace is kept free from solid materials and ensures the functional reliability of the sealing elements. <IMAGE>

IPC: E04B1/82
Filed: 1988-01-21
Abstract: For connecting elements which insulate with respect to structure-borne sound, use is made of metal/rubber elements.
