Title: Metallurgical evaluation of blast furnace burden - esp. of copper metallurgy by radionuclide tracer technique
Inventor: MAASS WOLFGANG DIPL ING
IPC: G01N33/20
Filed: 1979-06-21
Abstract: In the metallurgical evaluation of the blast furnace burden components of a poly-burden mixt. and for determining the output index in the individual process steps. esp. of Cu pyrometallurgy, by a radionuclide tracer technique, novelty comprises grinding the sample to 0.1 mm., weighing out analytically correct proportions and mixing with 7 vol.% sulphite waste liquor. Cylindrical briquettes of compsn. are pressed, having a cylindrical central cavity for accepting the standard aliquot and a monitor probe, pref. of Cu wire. A standard aliquot, of the same substance as the briquettes but without the sulphite waste liquor, and sealed in an ampoule of quartz, polyethylene or polystyrene, is introduced into the cavity. The briquette is provided with 3 monitor probes, esp. of Cu wire, at its outer surface, parallel to the longitudinal axis and at an angle of 120 degrees, and sealed, with aliquot and probes, in an Al capsule having the size of the briquette. The capsule is chemically and system-isotopically marked radioactively. Directly before charging on a burden, the Al capsule is opened with a bolt circle saw; standard aliquot and monitor probes are removed, the Al capsule is re-sealed and fed, with the burden, to the metallurgical process. The added total radioactivity impulse of the metal investigated in briquette is determined from the standard aliquot and monitor probes. Activity/wt. of sample material is determined by gamma-spectrometry of the radioactive samples of the individual smelting prods., after grinding at const. grinding time. Alternatively, the samples are worked up chemically and then evaluated. The intervals for measuring the radioactively marked burden components can be chosen. The process can be carried out at a selected moment on an opt. pyrometallurgical aggregate. Total activity measurement accuracy is >1%.

Title: Power operated compass saw - has blade taper edge spring biased against roller to prevent tearing of teeth
Inventor: GEBHART SIEGFRIED
IPC: B27B19/04
Filed: 1979-10-26
Abstract: The power operated compass saw has a blade (1) clamped at an upper end in a supporting structure. At its lower end the blade (1) has a taper (18) on the rear edge such that, on downward movement of the blade the tapered edge engages with a roller (19) to be moved towards the material being cut. A spring (21) biasses the blade (1) against the roller (19). On its upward movement, the blade is moved by the spring free of the material as the taper moves on the roller, thus preventing tearing of the teeth of the blade. The spring also assists the drive motor during downward movement of the blade.

Title: Toxic air components sepn. - by fibre mat filters sprayed with absorption agent
Inventor: ZAKRZEWSKI ERHARD
IPC: B01D53/54
Filed: 1979-11-23
Abstract: Toxic components, specially nitrous gases, are removed from gas-air mixtures by merging the mixt. with absorption agents. The mixt. is merged with an absorption agent in a concurrent flow in one or more stacks of laminated filter pads, made of chemically resistant fibre mats. The admixture of absorption agents is controlled by pH or redox adjustment or by colorimetric measurement. This requires no elaborate columns with plates or packings and achieves a higher sepn. efficiency.

Patent DE-3005587-A1 (DE)
Inventor: DIAS FRANCISCO JOACHIM ING GRA
IPC: C04B35/56
Filed: 1980-02-15
Abstract: Refractory parts or articles, even of very large dimensions, are made with a starting material of carbon particles mixed with silicon particles in a predetermined ratio which is suspended in a solution of a binder, after which the suspension is squirted into a precipitating liquid to coat the particles with the binder, the solids then being separated and dried, molded under slight pressure, and coked (at 800 DEG -1,000 DEG  C.), and then rapidly raised in temperature (to 1,400 DEG -1,600 DEG  C.) for formation of silicon carbide throughout the article. It is useful to add powdered silicon carbide and mix it in before the coking step and, also, to hold the heated body at a temperature somewhat below 1,400 DEG  C. long enough to remove temperature gradients within it, followed by rapid heating up to a carbide-forming temperature. The porous bodies thus formed can be heated to reduce porosity after the coking step by impregnation with a suspension of silicon powder in a resin, after which the body is again coked, or impregnation may be carried out on the completely fired body, with a liquid resin or a molten metal, after evacuation of the porous body and the application of pressure to the impregnating fluid.

Title: Ultrasonic transducer with time variable magnetisation - has laminated yoke core generating magnetic field lines parallel to test specimen surface
Inventor: REPPLINGER WILHELM DIPL ING
IPC: B06B1/02
Filed: 1980-05-07

Patent DE-3127091-A1 (DE)
Title: Method of producing a dental impression and impression tray
Inventor: LUDWIGS HORST
IPC: A61C9/00
Filed: 1981-07-09
Abstract: During production of a dental impression, the trimmed or prepared teeth to be reproduced are initially covered by a distance coating (spacer). A pre-impression of the covered teeth is made with a pre-impression material, a final impression composition is then placed in the gap in the pre-impression composition formed by the distance coating and a final impression is then made with the pre-impression prepared in this way after discarding the distance coating. Impurities, particularly, pools of blood at the cervical border of the gingival sulcus falsify the impression of the prepared teeth and their environment during the final impression. The improvement of this method resides in the fact that the final impression material now rests against the teeth to be reproduced so that it follows their contours exactly without being affected by any impurities. For this, the gap in the pre-impression composition is opened toward the outside at two points between which the tooth or teeth to be reproduced is or are located. The pre-impression is initially placed on the denture without the final impression material, and thereafter a stream of a free-flowing medium which entrains impurities is passed through the gap. Along the path of the free-flowing medium the final impression material is then passed into the gap between the pre-impression composition and the teeth. This method is conducted using a special impression tray having passage holes, so that opening of the gap surrounding the prepared teeth can take place through the material of the impression tray.
