Patent DE-3040669-A1 (DE)
Title: Continuous coating applied to insulation on electric cable - where soot or graphite powder is rolled onto insulation to form compacted electrically-conducting layer used for cable screening
Inventor: NORDMEYER FRIEDRICH DR ING
IPC: C23C24/02
Filed: 1980-10-29
Abstract: Powdered soot or graphite is fed continuously onto the insulation on an electric cable. The powder is then rolled so that it is compacted and/or smoothed to form a continuous conducting coating on the insulation. The powdered soot or graphite pref. contains a binder to assist its consolidation round the insulation. The pref. coating appts. includes at least two rolls located in a ring cage which is rotated round the cable, so the rolls rotate on the powder coating. Each roll may also be driven. The compacting rolls may be followed by a set of smoothing rolls. The surface of the rolls pref. consists of steel or a felt. A simple and reliable method is provided for forming a conducting carbon layer in a cable; this layer is used esp. for screening.

Title: Digital tone generating circuit for electronic organ - produces tone sequences using oscillator, frequency divider and modulator
Inventor: SCHLOSSER GEORG DIPL ING
IPC: B06B1/02
Filed: 1980-11-18
Abstract: The circuit produces a sequence of two or more tones and controls their decay. A switch actuates a voltage stabilising circuit (ST) whose output supply voltage actuates an RC oscillator (O) and the remaining circuit components. The oscillator is coupled to a frequency divider (TT) whose output feeds a sequencer (AS) and a modulator (Mo). The modulator's outputs pass via d-a converters (DA1-DA3) to a mixer (M) whose output is amplified and passed to the loudspeaker (L). The advantage lies in relatively few components.

Filed: 1981-01-13
Abstract: The invention relates to a machine for the stacking of articles, especially of ready-bound books, possibly provided with protective wrappers, or of not yet ready-bound books, for use on a production line, with which the stacking of the books fed to the upper part of a stacking shaft by means of a feed conveyor takes place on supporting devices arranged in the stacking shaft, in such a way that the upper end of the stack obtained is uniformly at a predetermined height. The finished stacks are finally lowered, deposited on a roller conveyor and automatically pushed to a position, from which they are automatically lifted, by means of a vertical conveyor having supporting battens fastened to endless chains and equipped with rollers, up to a discharge device which is essentially at the same height as the feed conveyor.

Title: Adhesive tape
Inventor: HIROSE TOKUZO
IPC: A47G11/00
Filed: 1981-01-21
Abstract: An adhesive tape wherein, for engagement with a "magic" or touch-and-close tape which bears on its surface a multiplicity of closely applied short fibres of hooked or mesh shape, a surface of a backing film is filled closely with fine short fibres of a fitting hooked or mesh shape corresponding either to the mesh or hooked shape of the touch-and-close tape, while an adhesive is applied to the second surface of the backing film. As a result, objects to be connected to one another in a simple and releasable manner can be connected by the interaction of the adhesive and the touch-and-close tapes, and the adhesive tape can be used to a great extent particularly whenever a high adhesive force is required in the sliding or slipping direction.

IPC: C08K5/25
Filed: 1981-08-06
Abstract: A method for stabilizing organic polymers against copper-catalyzed oxidative decomposition by means of N,N-bis-salicyloyl hydrazine as a metal deactivator is described wherein dust development of the metal deactivator is precluded with certainty and negative property changes of the stabilized organic polymers are avoided. For this purpose, it is provided that a paste which contains finely-crystalline N,N'-bis-salicyloyl hydrazine in fine distribution in a liquid to wax-like aliphatic hydrocarbon of low volatility is worked into the polymer. The method is particularly well suited for stabilizing polyolefins for cable and wire insulation.

Patent DE-3151549-A1 (DE)
Title: Stimulation device
Inventor: MAURER DONALD D
IPC: A61N1/36
Filed: 1981-12-28
Abstract: The device serves for the electrical stimulation of living tissue, such as organs of the body, muscles and nerves. The device can be mounted on the surface of the body or implanted in the body. The device has an electric circuit which contains a pulse width control device (41) for varying the intensity of stimulation, the pulse repetition frequency and the pulse duration for varying the pulse width. Variation of the pulse width causes the intensity of stimulation to vary in a prescribed mathematical fashion, so that it approximately follows the curves of intensity/duration or pulse stimulation amplitude versus pulse width. This enables optimum choice from among the various classes of stimulated nerve fibres inside a nerve bundle. Stimulation can be precisely adjusted, so that the feeling of the soothing of pain is optimised. <IMAGE>

Abstract: A drawer magazine (1), especially for the stockkeeping and/or storage as well as for the transport of small articles, is to acquire a design which allows its drawers to be used as an independent, especially stably stackable storage system, but which nevertheless can easily be used movably independently of such a storage system. For this, the drawers (15) consist of stackable storage boxes, especially display storage boxes, having laterally and upwardly angled stacking edges (16) arranged continuously on at least three sides, and the stop faces on the housing (2) are formed by webs (18) directed downwards from the upper front limiting edge of each compartment (3) into the clear space of the compartments (3). At the same time, at least the upwardly angled flange (17') of the rear stacking-edge portion (16') can, in the pull-out position, be brought to bear as a counterstop against the webs (18). Catch bosses (37) are formed on the bottom at a distance (36) in front of the rear push-in limitation (11') of each compartment (3'). The display storage boxes forming the drawers interact with these catch bosses in the pushed-in position by means of countercatches (38) arranged near the bottom at their rear end. <IMAGE>
