Patent EP-0538280-A1 (EP)
Inventor: ZIMMERMANN BERNHARD
IPC: H01C10/30
Filed: 1991-06-27
Abstract: Un commutateur, notamment pour régler le régime de moteurs électriques ou similaires, comprend un élément de résistance monté en surface qui sert de piste de résistance pour régler le régime. L'avantage de cette construction est le fait que la plaquette de circuits imprimés et la piste de résistance peuvent être fabriquées séparément et peuvent être individuellement optimisées. On peut mettre en oeuvre des procédés modernes de fabrication, tels que le montage automatique en surface des composants et l'égalisation au laser, indépendamment du montage usuel de la plaquette de circuits imprimés, ce qui permet de fabriquer économiquement le commutateur en grandes séries.

Abstract: La fabrication de pièces ayant une forme de base circulaire, lesquelles sont munies de saillies en forme d'arête, p.ex. de roues dentées, ne pouvait se faire jusqu'à présent que dans les procédés de fraisage par développante et de mortaisage par développante à l'aide d'outillages coûteux. Grâce à une superposition d'au moins deux mouvements circulaires, il est possible de guider un outil sur une trajectoire cycloïde, de manière à pouvoir prédéterminer, pour la zone de prise avec l'outil tournant, pratiquement n'importe quel tracé de ligne de coupe désiré, même une ligne de coupe rectiligne. Ceci permet de travailler avec des formes d'outil simple et avec des matériaux de coupe fortement sollicités, comme on les connaît dans le travail de tournage normal.

Abstract: In order to protect shaft, mine and tunnel constructions, in their development phase, against earth and water invasions, the earth is strengthened in the surroundings of the works by freezing. In particular when the freezing procedures are integrated into the continuous construction operation, delays and operational standstills in the subsequent works can come about freezing is too slow. For the purpose of accelerating the freezing, water is extracted from the earth by delivery wells (4) before or during freezing.

Abstract: The measuring device (1) comprises a scale graduation element (3) provided with a number of tracks, a pick-up device (5) which comprises a number of sensing elements (4, 6) provided with sensors, which number corresponds to the number of tracks, and also comprises a signal processing system (7). The tracks include an incremental track and an absolute track. Both tracks are formed as a succession of strip-shaped parts, each of which has a property which can be detected by the sensors of the sensing elements (4, 6). This property is dependent on the location on the scale graduation element (3). This property is preferably bivalent. In the signal processing system (7) signals originating from the sensing element (4) associated with the incremental track and signals originating from the sensing element (6) associated with the absolute track are combined. 
     On the absolute track the property is distributed in a pseudo-random fashion between the strip-shaped parts so that the combination of signals for a pitch of the incremental track produces a specific value for each pitch. Consequently, the measurement value produced by the signal processing system (7) is absolute.

Abstract: Apparatus located in an implantable medication infusion pump (126) for quickly and easily detecting a condition adversely affecting medication delivery in the infusion pump. The system uses the amplitude of an acoustic signal (piezo sensor (150)) generated by operation of the pumping mechanism as compared with a baseline signal to detect an encapsulated or occluded catheter (132) or air in the fluid line. The system can detect occurrences including an occluded catheter (132), the presence of air in the pumping mechanism (126), and the failure of the pumping mechanism (126). In addition, the system can detect a partially encapsulated or occulated catheter by detecting repeated downward slope patterns during repetitive, closely spaced pumping cycles.

Abstract: A process for efficiently recovering metals such as nickel, cobalt, and manganese from oxide ores such as laterite and garnierite, said process comprising subjecting an atmospheric leaching residue to sulfuric acid leaching under a high temperature and high pressure conditions in an oxidizing atmosphere, and then carrying out atmospheric leaching on the high pressure leaching solution thus obtained together with the slurried oxide ore, in an acidic sulfuric acid solution. After neutralizing the atmospheric leaching solution thus obtained, an alkali sulfide compound is added therein to recover nickel and cobalt as sulfides. Then, a carbonate is added further to the resulting solution to recover manganese as a carbonate. Furthermore, the solution from which the metals are recovered is circulated for use as a rinsing solution, flocculant solution, and as water for slurrying the oxide ores.
