Title: Method and installation for processing scrap
Inventor: PIPER KARL-ERICH DIPL ING
IPC: B07C5/344
Filed: 1989-05-23
Abstract: The invention relates to the processing of scrap of a non-magnetic metal, which consists at least partially of chips and contains ferromagnetic cutting material particles drawn in with these, the precleaned scrap being guided, after other processing, through an additional magnetic field and residues of ferromagnetic cutting material particles thus also being magnetised.

Patent DE-4014149-A1 (DE)
Inventor: WAGNER HANS DIPL ING
IPC: G01R31/308
Filed: 1990-05-02
Abstract: In automatic insertion devices, testing the printed circuit cards before and after soldering constitutes an important factor in the production process. It is therefore necessary to specify test procedures which guarantee reliable evaluation at different stages of production. In the method according to the invention, reliable statements about the presence or the correct position of the components can be made by assessing the relative position of the components with respect to the terminal areas. For this purpose, the test specimen is illuminated without shadows by means of a planar, diffuse light source. The parts of the terminal areas not covered reflect the light very strongly. In this way, it is possible by recording an image of the printed circuit card to be tested and evaluating the video signals of the parts, not covered by the components, of the terminal areas with respect to their size and shape to reach a conclusion on the absence of defects in the printed circuit card. <IMAGE>

Date Nov. 28, 1991.The volume of water in circulation is controlled by means of a bell-type mixer (4) which has a stationary section disc (6) and a somewhat sickle-shaped rotary distributor bell (7). The section disc has at least three separate passage openings, the first of which is connected with the boiler feed pipe (KV), the second (12) with the heating pipe (HV) and the third with the boiler return pipe. The distributor bell (7) is acted upon externally by the heating return water pressure and internally housing a communication duct (19). The distributor bell shunts the boiler feed pipe over a limited area of rotation via the second passage opening (12) with the heating pipe and simultaneously frees a variable area of the opening into the second passage for the admixture of return water. In this way optimal regulation is achieved with little structural, maintenance or operational outlay.
