Title: Model device for the preparation of a dental attachment by metal casting, and a process for forming such an attachment
Inventor: RADEMACHER BERND
IPC: A61C13/265
Filed: 1984-09-25
Abstract: In a model device for the preparation of a dental attachment by metal casting, an attachment part (female) retained on the pillar crown is used, and on to this a counterpiece (male) 3 releasably connected with the prosthesis 6 can be pushed vertically with sliding fit. A conical peg 36 for accommodation of a corresponding, conical, slotted guide sleeve 41 which is cast-on with a space-retaining duplicating sleeve by the duplicating method, is provided on this counterpiece 3.   The appropriate duplicating method is used to put the space-retaining duplicating sleeve on to the conical peg 36 of the counterpiece 3 inserted in the attachment part retained on the pillar crown, and the sleeve is coated with wax in order to form the investment material model. After formation of the latter model the plastic jacket and a retention of the duplicating sleeve are combusted during the subsequent drying and curing of the model. This is followed by filling the investment material model with metal, the inner guide sleeve 41 joining up with the metal of the prosthesis 6 and at the same time forming the receptacle for the conical peg 36 of the counterpiece 3. <IMAGE>

Title: Process for producing purified phosphoric acid
Inventor: IOSEF ALEXANDER
IPC: C01B25/234
Filed: 1984-10-22
Abstract: A process is disclosed for producing purified phosphoric acid from phosphatic rock. In this process, the phosphatic rock is decomposed with mineral acids, for example with acid and/or sulphuric acid. The solution liquor obtained is neutralised with a calcium-containing compound, such as calcium oxide, calcium carbonate, tricalcium phosphate or powdered phosphatic rock, thereby producing an aqueous solution containing 0.4 to 5.5 % by weight of CaO. After the precipitated solids have been separated off, the phosphatic constituent is extracted from the clarified solution using an organic solvent. The phosphoric acid is subsequently produced from the solvent extract using known methods, such as washing-out or distillation.

Title: Shaft seal
Inventor: WEHRFRITZ HEINZ DIPL ING
IPC: F16J15/16
Filed: 1984-10-23
Abstract: The invention relates to a process for sealing off one machine part, rotating relative to another and projecting from this, by means of a shaft-sealing ring connected firmly to the rotating machine part and having axial or radial elastic sealing lips of known design, so that, at a standstill or in the event of slow relative movements, hermetic contact sealing is provided, and in which, at an increasing relative speed, the sealing lip is relieved in a predeterminable manner controllable from outside, lifts off from the sealing face and changes into a contactless shaft seal. According to the invention, compressed air is blown in between the shaft-sealing ring and the sealing face via a ring of nozzle bores and a pressure cushion is thereby generated. Advantageously, the compressed air assisting the lift-off of the seal is cut in only in the starting phase or at low speeds. The invention relates, furthermore, to an apparatus for carrying out this method.

Patent DE-3510664-A1 (DE)
Title: Lightweight mirror
Inventor: ERNST WOLFGANG
IPC: G01B11/245
Filed: 1985-03-23
Abstract: The enormous reduction in weight and lowering of production costs are the characteristics of the carbon-fibre- and epoxy-resin-based mirror support to be vapour-coated. In comparison with conventional mirror supports, this simplifies use in large telescopes and, if appropriate, in space. Production is performed with the aid of a prefabricated positive body, from which in each case two component pieces consisting of a plurality of layers of carbon fibre of different weighting are taken. The epoxy resin bonds the layers homogeneously. The two paraboloids thus produced are connected by means of lamellae, likewise produced from carbon fibre, which are intermeshed and form a uniform network, thereby achieving the stability of the mirror support. The chambers thereby produced have to be ventilated. Final jobs which remain are to close the edge remaining open between the component pieces and to fit wedge-shaped mountings for the purpose of forming a planar bearing surface on the convex side of the paraboloid (the concave side is vapour-coated). In addition to long curing times, to finish off the mirror support is once again conditioned in order to make the coefficient of thermal expansion approach zero.
