Patent DE-4214035-A1 (DE)
Title: Bases for settings of jewels etc. or for producing handicraft items - consists of hot melt adhesive which is e.g. cast over jewels set in wet clay, allowed to cool, and then readily released from the clay
Inventor: BODEN NICOLE
IPC: B29C39/00
Filed: 1992-04-29
Abstract: The bases for jewellery and articles of handicraft are made of hot melt adhesive; as an example a base set with pearls is produced by placing pearls in a negative mould of moist clay and casting hot melt adhesive in. Moist clay is an excellent material for the techniques as it adheres so well to jewels, etc. but does not adhere to the hot melt adhesive. When the adhesive has set solid its bond to the jewels, etc. is stronger than that to the clay, so that the jewels are readily released. Other methods however can also be used, e.g., starting with a positive mould to cast A negative in the adhesive, here the starting mould is wet plaster. By choice of colour of the adhesive different decorative effects can be obtained. The clay or plaster moulds can be water-cooled much faster than silicone. The process also has advantages over conventional methods using a centrifuge; another variant is to place an irridescent film over the base. Many other items, e.g., toilet boxes, etc. can also be produced besides jewellery bases, etc. ADVANTAGE - The principle makes it very simple to produce the jewellery, etc. which is nevertheless hard-wearing. It is cheap. The products can be made in almost any size and shape.

Patent DE-4317408-A1 (DE)
Title: Method for reducing contact resistances due to corrosion, on anode and cathode rails of electrolytic baths, and arrangement for implementing the method
Inventor: KOSIKOWSKI THOMAS
IPC: C25D17/00
Filed: 1993-05-18
Abstract: The invention relates to a method for reducing electric contact resistances due to corrosion, on the anode and cathode rails of electrolytic baths. The parts attached to the rails as a rule consist of a material which is different from that of the rails. The aggressive ambient conditions close to electroplating baths cause corrosion and consequently an uncontrolled increase in the resistance at the junction of the materials. This is avoided, according to the invention, by a partial combination of corrosion-resistant material for the contacts (2), preferably alloy steel (high-grade steel) with a highly conductive material for the rails (1), preferably copper. A gas-tight junction (4) of materials is produced by press-fitting, welding, friction-welding, pulse welding or soldering (brazing). It thus eludes troublesome corrosion. <IMAGE>

Title: Band brake for units driven by internal combustion engines
Inventor: KRAPPMANN KLAUS
IPC: F16D65/04
Filed: 1993-09-30
Abstract: The invention relates to a band brake for braking and bringing to a halt units driven by an internal combustion engine which, for safety reasons, must be brought to a halt immediately, i.e. after a defined short deceleration time, after being switched off. The use of the band brake, which interacts directly with the pole wheel of the internal combustion engine, is coupled to the ignition current of the internal combustion engine in such a way that as soon as the internal combustion engine is switched off, the braking action, brought about by the release of a Bowden cable, begins by the activation of a tension spring. A gentle but powerful response is achieved by a brake lining of reduced thickness which is bonded to the circumferential surface of the pole wheel and thus revolves with the latter. The brake band itself has no lining.
