Abstract: Ce procédé est destiné a être mis en oeuvre avec un réducteur de mesure haute tension à effet Faraday comportant un interféromètre de Sagnac ayant une boucle optique formée d'une fibre (47) montant au potentiel entourer le conducteur 11 parcouru par le courant alternatif à mesurer et aboutissant sur un circuit en optique intégrée (43) délivrant à une platine électronique (46) un faisceau lumineux de sortie dont la puissance optique a une composante de son spectre de fréquence qui est une fonction sinuoïdale de l'écart de phase engendré par l'effet Faraday dans le rapport d'un facteur d'échelle. Il consiste en une mise à jour périodique de ce facteur d'échelle à partir des composantes continues du signal de sortie de l'interféromètre en réponse à deux pertubations successives qui modifient l'effet Faraday et qui sont provoquées à l'aide d'un courant continu de test prenant deux valeurs successives distinctes et parcourant des enroulements auxiliaires (44, 45).

Abstract: The invention relates to a method for coating objects by means of a coating powder which emerges from the distribution member of a coating plant and is moved by electrostatic forces towards the object to be coated. The coating powder adheres to the object and is converted into a cohesive layer of material by the action of heat and by fusion. The coating powder used is produced from powder raw materials and provided with powder additives suited to the particular application. The method followed is that a crude coating powder, substantially comprising only the powder raw materials and produced by mixing, extruding and pulverisation, is prepared, the additives being added thereto only after its preparation, the additive in question being sprayed in liquid form onto the particles of the crude coating powder, so that the latter are given a coating of additive.

Abstract: For the optimum design of a steam fluidised bed drying installation, it is proposed to use, for heating the steam fluidised bed, a straight-tube bank (3) which is rolled or welded in the wall (5) on the inlet side and has a floating head exchanger on the other side. The straight-tube bank (3) has a number of steam runs (4, 4', 4'', 4''') so that the speed distribution of the steam is evened out in the individual tubes of the straight-tube bank. The corresponding condensate is deposited in the collecting and distributing chambers (6, 7) so that the flow resistance, in particular in the last steam runs, is not greater than in the first. There is consequently a considerably different number of tubes in the individual steam runs. <IMAGE>

Abstract: A semiconductor laser apparatus detects a laser beam from a semiconductor laser element (11) using a light-receiving element (16) so as to perform automatic light power control. A temperature dependency of the power of a laser beam transmitted through an end face protection film (14, 15) of the semiconductor laser element (11) and the temperature dependence of a detection power of the light-­receiving element (16) have inverse characteristics to each other, so that a variation in intensity of output light due to a change in temperature is minimised.

Abstract: Methods for forming or purifying organometallic compounds of elements of Group III-A of the Periodic Table. An intermediate compound is formed which is an adduct of the desired organometallic compound and a Group I-A or Group II-A compound. The adduct is nonvolatile, so volatile impurities are removed from the adduct by distillation. The adduct is decomposed to release the volatile organometallic compound, which is then distilled away from the nonvolatile remainder of the adduct. The method can be used to produce organometallic compounds which are substantially free of volatile metallic compounds and complexed solvents. A method of separating volatile Group II-B impurities from volatile Group III-A compounds is also disclosed.

Title: Amortisseur a plateaux multiples utilisant un fluide visqueux

Abstract: Amortisseur dans lequel des plateaux mobiles (6) auxquels une force externe est transmise et des plateaux fixes (7) qui ne sont pas reliés fonctionnellement aux plateaux mobiles sont agencés en alternance dans un carter (1) contenant un fluide visqueux (A). Tant les plateaux mobiles (6) que les plateaux fixes (7) sont formés de manière à pouvoir se déplacer dans le sens de leur épaisseur. La distance entre les plateaux peut ainsi être régulée de manière uniforme grâce à l'effet d'alignement des plateaux, de manière à éviter que les plateaux ne soient soumis à une force trop intense qui les endommagerait. Pour permettre le réglage manuel de la force de freinage de l'amortisseur, la tolérance de déplacement des plateaux mobiles (6) et des plateaux fixes (7) peut être modifiée, ou alors le nombre et la taille des plateaux mobiles (6) et/ou des plateaux fixes (7) sont variables. Afin d'éviter que la force de freinage de l'amortisseur ne s'exerce dans une mauvaise direction à cause des variations de la température ambiante, on prévoit un élément déformable sensible à la température, ou les plateaux mobiles (6) et/ou les plateaux fixes (7) sont composés d'un matériau déformable sensible à la température. Cet agencement permet de maintenir automatiquement constante la force de freinage.

Abstract: On prépare un matériau à transfert thermique en déposant une couche (13) d'encre thermofusible sur l'une des surfaces d'un film de base (11) par l'intermédiaire d'une couche adhésive (12) et en déposant une couche (14) de régulation de transfert sur la couche d'encre thermofusible. Ce matériau permet des transferts multiples. Etant donné que la couche adhésive déposée colle fermement le film de base sur la couche d'encre thermofusible, le décollement au niveau de l'interface entre le film de base et l'encre thermofusible pendant l'impression est évité, tout en maintenant la fonction de la couche de régulation de transfert. On peut ainsi réguler de manière appropriée la quantité d'encre transférée par l'intermédiaire de la couche de régulation de transfert.

Title: Methods and apparatus for forming pressed glass articles.
Inventor: ZIEGLER MICHAEL J
IPC: C03B/
Filed: 1988-06-10
Abstract: A system for forming hollow pressed glass articles (20) utilizes a flow of cryogen that is mixed with air supplied by tube (50) to provide a cooling gas that enables newly pressed articles to be removed from their molds after a thin skin of solidified glass has been formed on internal surfaces of the articles. Two flows of cryogen are used, one being a gentle, substantially continuous flow of cryogen gas, the other being a controlled intermittent flow of cryogen vapor in liquid and/or gaseous form. To assure a proper introduction of cryogen vapor, and to prevent debilitating accumulations of ice within and about the tube that is used to inject high pressure cryogen, the high pressure injector tube (62) is surrounded by a low pressure cryogen tube (64), through which a flow of low pressure cryogen gas is maintained on a substantially continuous basis.

Abstract: The invention relates to a cutting tool with cutting jaws mounted pivotably about bearing pins, the mounting being formed by means of straps connecting the cutting jaws at the back of the cutting-jaw region and by means of a tooth-gap engagement (ZL) binding the two cutting jaws to one another. While retaining the known crossing overlap, the one-piece design of gripping limbs (1, 2) and pliers-type jaws (3, 4), the invention proposes, in order to increase the cutting efficiency, that the pliers-type limbs be designed to cross over without pivot pins.

Abstract: The invention relates to a contactless transmitting method for physical quantities measured in a rotating component (3), which quantities are detected by a sensor (10) and are converted into electrical values, the sensor (10) being supplied with power via an induction coil pair (15a, 15b) which bridges the air gap between the rotating and the fixed component, and a further induction coil pair (16a, 16b) being provided to transmit the electrical values. The measured values emitted by the sensor (10) are converted directly into a current signal which is passed in the rotating component (3) as an analog signal via two measurement leads (13) to the transmission coil (16a) of the induction coil pair (16a, 16b), is digitised immediately before transmission and is transmitted in serial form from the rotating component to the fixed component. The power transmitted via the second induction coil pair (15a, 15b) into the rotating component is supplied to the sensor (10) via the same measurement leads (13) in a defined range which lies outside the measured value transmission range. <IMAGE>
