Title: Coupling, junction-forming and combining light conductor fibres - using supporting body with grooves for fixing fibres and grinding or polishing region of grooves
Inventor: DESERNO ULRICH DR PHIL
IPC: G02B6/28
Filed: 1980-09-30
Abstract: The branch coupling is built-up from two different type coupling halves, namely a supporting body with a curved fibre and a supporting body with a face-end fibre element, having two, three or four entrances. By combining several such components, elements can be produced, having more than four entrances. Only three process steps are necessary to produce these components, -one- the production of a suitable supporting body, with guide channels for the fibre, -two- the fixing of the fibre or fibres in the guide channel, and three the grinding and polishing of the supporting body. A simple coupling can consist of two fibres (3,4) whose face-ends butt up flush with one another. The method of building up a coupling is suitable for mass production methods.

Title: Secure axial fastening of a machine element
Inventor: TROESTER MANFRED DIPL ING
IPC: F16B21/18
Filed: 1981-03-25
Abstract: The invention relates to the secure axial fastening of a machine element, in particular roller-contact-bearing race, on a shaft or in the housing under axial prestress with the aid of a tubular ring which bears, on one side, in a groove and, on the other side, on the side surface of the element to be fastened. The secure axial fastening is achieved in that, with an axial oversize, the slotted approximately S-shaped ring comes to bear, by means of its end surface, in an axial annular cutout on the element to be fastened. The intended result is that, even in the event of very high axial prestresses, no radial forces or overturning moments are exerted on the element to be fastened. <IMAGE>

Patent DE-3122899-A1 (DE)
Title: Temperature switch
Inventor: HOFSAESS PETER
IPC: H01H37/54
Filed: 1981-06-10
Abstract: The subject-matter of the invention is a temperature monitor (10). Such temperature monitors are known which, in addition to an active bimetallic snap-action disc, have a spring snap-action disc which produces the actual contact pressure in a closed position. For switching, the bimetallic snap-action disc must overcome all the force of the spring snap-action disc producing the contact pressure. In order to apply a corresponding force, the bimetallic disc must either be designed to be large enough, or the contact pressure forces must be so low that the conduction and switching behaviour is relatively poor. In order to achieve the object it is proposed according to the invention that two prestamped spring snap-action discs (22, 24) be provided and that the spring snap-action discs (22, 24) be arranged in opposite directions to one another. The solution according to the invention makes it possible to achieve contact pressures which ensure high reliability of the monitor (10), using small bimetallic snap-action discs (26). <IMAGE>

Patent DE-3136427-A1 (DE)
Title: Print head
Inventor: WIEDEMER MANFRED
IPC: B41J2/06
Filed: 1981-09-14
Abstract: Contained in the print head is a cavity in which writing liquid, e.g. ink, is contained. Two electrodes which can be connected to high voltage are arranged in the cavity. In this case, a spark discharge is formed between the electrodes (10, 12), which produces a pressure wave through which a droplet of the writing liquid is ejected through an opening in the cavity. The cavity is formed in the first electrode (10) which has a U-shaped cross-section and whose central part is provided with a slot (30). The second electrode (12) is mounted in a support (32) made of insulating material which has a projection (34) which can be inserted in the slot (30) and seals the latter off tightly. Fastened on the central piece of the first electrode (10) is a printing plate (36) which closes off the slot (30) towards the outside and is provided with an opening (18) through which, during spark discharge, the droplet of writing liquid thus produced emerges towards the outside. <IMAGE>

Patent DE-3143615-A1 (DE)
Title: Spreading anchor
Inventor: MAECHTLE ROLAND
IPC: F16B13/00
Filed: 1981-11-03
Abstract: In a spreading anchor (4) for mounting in a cylindrical drilled hole (6) which has a widened area (12) and is supported in the drilled hole via bolts (32) which can spread out into the widened area (12), it is proposed for the bolts to pivot outwards into the widened area (12) by means of a cylindrical expanding sleeve (24). This has the advantage that the bolts (32) are completely pivoted out even when, because of faulty assembly or because of deformations of the spreading anchor, the expanding sleeve (24) moves itself away, out of its desired position, from the bolts (32), to a greater or lesser extent, in the event of cracks occurring subsequently in the base material (8). <IMAGE>
Patent DE-3143637-A1 (DE)
Title: Method of applying a two-part fastening element, such as a stud button, to flat products, such as textile webs of garments
Inventor: NYSTEN BERNHARD DIPL ING
IPC: A44B1/28
Filed: 1981-11-04
Abstract: In a method of applying a two-part fastening element, such as a stud button, to flat products, such as textile webs of garments, the issue is to connect an insertion part provided with at least one pin to a receptacle for the retaining part exhibiting the pin end. For this purpose, pin parts and retaining parts are placed on opposite sides of the flat product and the insertion part is then driven through the flat product by its pin until its end is pressed out on the opposite side and serves for receiving the retaining part. In order to avoid high manufacturing and material expenditure for a positive fastening between the insertion and retaining parts, it is proposed to pass an electric current surge between the insertion and retaining parts when the parts are pressed on, which current surge causes the contacting points between the pin and its receptacle to melt as a function of the given material thickness of the flat product. The cooled melting points form a weld connection between the insertion and retaining parts which has a high resistance to disconnection.
