Title: Anchoring hooks for cables
Inventor: WEINBRENNER ALFRED
IPC: H02G7/02
Filed: 1988-11-10
Abstract: In the case of conventional anchoring hooks, which frequently consist of a groove which is wound in a spiral shape to form a ring, it is possible for the cable to be anchored to kink at the end of the groove.

The auxiliary slots (5, 5') are considerably more highly curved than the groove (1) and are mounted on a holder (4). Anchoring of optical waveguide cables. <IMAGE>
Patent DE-3843787-A1 (DE)
Inventor: HEIDEMANN ROLF DR
IPC: H01L23/373
Filed: 1988-12-24
Abstract: Printed circuit boards in which the components are secured by a sprung mounting plate are known. The mounting plate serves not only as current path but as cooling plate. Such a component fixture is not suitable for high-frequency applications. The problem of the invention is to mount high-speed chips (for frequencies of over 1 GHz), which cannot be built into small microwave housings owing to the requirements to be met for such high frequencies, on a board in such a way a connection suitable for microwave applications and the necessary heat dissipation from the component can be achieved with simple means. The basic idea of the solution is to connect the metallic base surface of the chip housing (2) to the metallic layers of the multilayer printed circuit board (1) via plated-through holes. For this purpose, the printed circuit board (1) is provided with through holes (21) which open into a mounting pad (20) on the printed circuit board (1) and which are in contact with planar conductor tracks (13, 14) in the printed circuit board. The housing base (4) is placed on the mounting pad (20) and the holes (21) are filled with a molten solder. This connects the housing (2) in a thermally and electrically conducting manner to the planar conductor tracks (13, 14). <IMAGE>

Inventor: FINK ROLAND
IPC: F16H21/44
Filed: 1989-04-07
Abstract: Pivoting device for a robot arm, wherein the part to be pivoted is rotatably mounted about a pivot axis.

Patent DE-3917650-A1 (DE)
Title: Occlusal position support with adapter
Inventor: MARX JOACHIM
IPC: A61C9/00
Filed: 1989-05-31
Abstract: The occlusal position support permits the dentist to record the bite provisionally in advance during the clinical preparatory work for a denture, such that this instrument is used to introduce a suitable impression composition into the mouth, so that the patient can close the mouth during preparation of the impression of the oral cavity. The shape of the occlusal position support permits this irrespective of the teeth that are still present in the mouth of the patient. This advance recording of the bite can thus be carried out in patients having all their teeth or only some remaining teeth, as well as in toothless patients. By this type of advance recording of the bite the dentist permits the dental technician to prepare a mouth model with the aid of which bite plates or recording equipment can be produced in a manner based on the skull coordinates. This occlusal position support with adapter simultaneously permits attachment and fixation of tranfer bows and makes it possible to carry out impression, advance recording of the bite and use of a transfer bow without further aids in a single session.

Title: Cleaning travelling machining-coolant filter belt
Inventor: HAEFNER JUERGEN DIPL ING
IPC: B01D33/04
Filed: 1990-12-12
Abstract: Contaminated liq, esp coolant contg metal chips from a machine tool, is received into an open-topped chamber along whose base passes a continuous filter belt supported on a chain above a low-pressure flat compartment for cleaned liq. An extension above the chamber end and into which the belt rises undergoes preliminary treatment to  detach loose coarse material, esp by gravity scraper or knocking, to be removed by a transverse worm conveyor. The belt then travels below a first row of spray nozzles operated at low pressure bars from a pump to detach loosely adhering material, Deeper cleaning of pores is provided by a row of high-pressure nozzles. Both sets of nozzles are enclosed in a common housing, together with a trap preventing spray dissemination.
