Patent DE-3711396-A1 (DE)
Title: Dressing tool
Inventor: RIEGGER WOLFGANG
IPC: B24B53/12
Filed: 1987-04-04
Abstract: For the fine-working of the working surface of a workpiece-working means, in particular a grinding wheel, which serves, for its part, for the fine-working of workpieces, use is made of a dressing tool which, in operation, is held in the radial direction against the rotating working surface and performs an axial feed movement relative thereto. The dressing tool has at least one dressing diamond which works the working surface using its free end face and is held in an embedding means. The dressing diamond, of which there is at least one, is ground to form a shaped body whose greatest width dimension parallel to the axis of rotation is the same throughout over its depth dimension reaching from the free end face into the embedding means. In this way, an effective width independent of the diamond wear is obtained.

Title: Magneto-optical store with a magnetic head integrated into the scanning unit
Inventor: KEGLER ERNST
IPC: G11B5/127
Filed: 1987-09-15
Abstract: In the case of conventional magneto-optical stores information is recorded by exposing/blanking out the radiation source while a direct-current magnetic field is applied at the same time. This requires an erasing procedure before the actual recording operation. Before the subsequent recording operation, the polarity of the magnetic field is reversed. This erasing procedure, which prolongs the processing time considerably, is to be eliminated. For this purpose there is provided a vertical magnetic head (23), which generates the magnetic field, forms a mechanical unit with a positionable optical scanning head (17) and is arranged with only an air gap separating it from the surface of a storage disk (10). While there is provided a radiation source (1), which continuously emits a radiation energy adequate for the recording of information, the magnetic head (23) is designed in such a way that it generates a vertically directed magnetic field with a direction of magnetisation controlled by the information to be stored. The storage disk (10) preferably has a magnetically conducting return layer (12) arranged underneath the magneto-optical storage layer (13). Rewritable optical store. <IMAGE>

Filed: 1987-09-17
Abstract: Box girders for double-girder bridge cranes are subjected to high compressive loading under the trolley wheel. This especially applies to the welds which connect the top chord (3) to the web plates (1). To relieve these welds, the top chord is formed from a rigid section, for example a T-shaped rolled section. To increase the torsional rigidity, the side plates can be at an angle so that a trapezoidal cross-section of the hollow-box section results. <IMAGE>

Patent DE-3739513-A1 (DE)
Title: Seal
Inventor: HEINRICH RICHARD
IPC: F16J15/3256
Filed: 1987-11-21
Abstract: The seal has a rotor bush arranged on a shaft and a sealing part with a sealing edge for radial sealing, which is held in the sealing position under spring force. The intention is that, apart from providing radial sealing, the seal should also provide axial sealing and be capable of being arranged in the installation space rapidly and in a simple manner. In order to achieve both axial and radial sealing with the seal and given that the seal is to be arranged in a fixed manner in the installation space, the sealing part has at least one further sealing edge, which is sealed off axially. In addition, the rotor bush forms a ready-to-install cartridge-like module with the supporting body. The rotor bush is arranged in a fixed manner on the shaft so that it rotates with it. Since the rotor bush is integrated into the supporting body, the seal can be installed rapidly and in a simple manner as a module, like a cartridge seal.

Title: Process for producing shaped bodies comprising highly pure SiO2
Inventor: URBACH HANS-PETER DR RER NAT
IPC: C03B19/06
Filed: 1987-12-07
Abstract: In a process for producing shaped bodies comprising highly pure SiO2, the base material is produced from technical grade SiO2 or SiO2-containing minerals by the so-called fibre leaching process, the leached fibres are finely milled after heat treatment thereof and the millbase is, optionally together with auxiliaries, stirred to form a slip. The slip is then cast into the desired moulds and the body taken from the casting mould is sintered. The process can be used for the production of apparatus (crucibles, pipes, plates) for laboratory and industrial purposes, which apparatus are characterised by high purity, mechanical and thermal data comparable with conventional quartz glass or quartz ware apparatus and low production costs. <IMAGE>

Abstract: The use of alginate as impression material for precision impressions for prosthetic crowns and bridges has recently attracted great interest for reasons of cost but to date has failed because the mechanical strength is inadequate. The present application relates to a fibre-reinforced alginate in which the mechanical properties are significantly improved by admixture of micro- and macrofibres.
Patent DE-3804099-A1 (DE)
Title: Process for treating ammonia-containing solutions
Inventor: SEIFERT KLAUS DIPL ING
IPC: B01J41/05
Filed: 1988-02-10
Abstract: The invention relates to a process for treating ammonia-containing solutions arising in a power station, which ammonia-containing solutions further contain anionic impurities, especially carbonate. Such solutions occur in particular as condensate from the evacuation systems of a turbine condenser. This pump condensate contains ammonia and carbonate. It is provided that the anionic impurities, in particular the carbonate, are first removed from the ammonia-containing solutions by an anion exchanger. A highly basic anion exchanger is suitable for removal of carbonate. The solutions freed of anionic impurities still contain ammonia. Since anionic solution contents, but not the ammonia required for conditioning, have an interfering effect on the water-steam circulation of the power station, the solution purified in the anion exchanger and still containing ammonia is returned according to the invention to the water-steam circulation. This reuse avoids the production of ammonia-polluted wastewater from the said source.

Abstract: Known methods require several operations for manufacturing conductive connections, for example between light bulbs and supply terminals. The new method is intended to reduce the number of these operations. In a first operational step, rigid contact parts, such as contact springs or the like, are mechanically fitted on the lamp holder and, in a second operation, the contact material is then applied in fluid or paste form in accordance with the route of the electrically conducting connection paths. The method is suitable for the manufacture of lamp holders, especially for motor vehicle construction. <IMAGE>
