IPC: G01G23/10

Abstract: A spring balance consists essentially of a measuring spring 1, a load dish 2 for placing an unknown weight 3 on it, a piston rod 4 and an inductive displacement transducer 8 which generates a measurement signal Um. There are two electrically controllable force members 13, 14 which each consist of a live coil 15, 16 and of a common magnetic core 17 fastened to the piston rod 4. An electronic control unit 18 controls the force members 13, 14 as a function of the measurement signal Um, in such a way that these briefly subject the moved elements to braking or acceleration forces acting parallel to the direction of displacement, but not proportional to the displacement speed. The transient phenomena can thereby be actively damped very effectively, so that the new position of equilibrium is reached in the shortest possible time. Adjustment times of less than a quarter of the period of the non-damped system can be obtained. <IMAGE>

Abstract: In order to provide a wear-resistant surface coating for the rollers of roller machines, in particular for high-pressure roller crushers for the pressure comminution of granular material, which surface coating has a high durability and can be built up economically on the basic body of the rollers, at least two superimposed layers of such materials built up on the basic body of the rollers are proposed so that a gradual increase in hardness and strength from the parent material of the rollers via the intermediate layer(s) to the clad outer layer is obtained in proportion to the radial distance of the layers from the basic body of the rollers.

Abstract: The invention relates to a spread of the water-in-oil type comprising an intimate mixture of particles of vegetable fats and of milk fat, wherein the spread possesses a structure which is to be obtained by forming an emulsion of at least water, molten vegetable fats and/or oils, a milk cream phase with a milk fat content of 5-70% and 0.5-3% of a lactic acid bacterial culture, subjecting this emulsion to a mechanical treat­ment while cooling to below 20°C and finally separating off the product obtained and storing it at a conversion temperature at which the lactic acid bacteria form lactic acid and butter aroma substances from substances belonging to the milk cream phase, is described. The total fat mixture preferably contains at least 40% poly­unsaturated fatty acids. The milk fat content of the milk cream phase preferably being 20-40%. The cream particles present after the mechanical treatment will separate out butter particles on storage. The cooling may be interrupted during the mechanical treatment. The conversion temperature is lower than 20°C. The spread is advantageously continuously prepared by forming an emulsion of at least water, molten vegetable fats and/­or oils, a milk cream phase with a milk fat content of 5-70% and 0.5-3% of a lactic acid bacterial culture, subjecting this emulsion to a mechanical treatment while cooling to below 20°C and finally separating off the product thus obtained and storing it at a conversion temperature at which the lactic acid bacteria form lactic acid and butter aroma substances from substances belonging to the milk cream phase.

Abstract: Est décrit un procédé pour faciliter l'élimination, par des moyens chimiques, de corps étrangers encastrés sous la peau (2), généralement dénommés échardes (1). Ce procédé consiste à appliquer de manière topique, sur la peau en un point adjacent à l'écharde (1), tel que le point (5) au niveau duquel l'écharde a pénétré dans la peau, une composition chimique renfermant de l'acide salicylique. Cette composition chimique peut également contenir un antibiotique pour activer la cicatrisation, et un véhicule tel que du pétrolatum. Lorsqu'elle est mise en contact avec la peau au niveau d'un point adjacent (5) à l'écharde (1), par un pansement (6) ou un autre support fixé sur la peau, la composition chimique provoque la desquamation de la peau au niveau de la lésion, une hydratation épidermique, et une désagrégation diffuse de l'écharde (1) noyée sous la peau.

Abstract: Raccordement fileté où la charge axiale entre une vis (11) et un écrou (15), lorsqu'ils sont vissés ensemble, est répartie de manière plus équilibrée entre les différents tours des filetages qui entrent en prise que dans un raccordement standard. A cet effet, le pas du filetage (14) de la vis (15) augmente progressivement (Pa, Pb, Pc) à mesure que le filetage avance hélicoïdalement dans un état axial prédéterminé, tandis que le pas (P) du filetage (13) de la vis (11) est uniforme sur toute sa longueur. Le pas du filetage de l'écrou (14) peut augmenter de manière prédéterminée pour compenser les variations de la force de traction qui s'exerce sur la vis (11) et de la force de compression qui s'exerce sur l'écrou (15) en différents points sur leur longueur lorsque la vis (11) et l'écrou (15) sont vissés ensemble jusqu'à un état précontraint.

Abstract: Un dispositif de mise en tension librement suspendu (134) possédant des moyens d'amortissement de mouvement et des moyens de stabilisation de l'effet gyroscopique s'utilise dans un système de transmission comportant un élément de transmission souple (135). Ce dispositif de mise en tension (134) comprend un ensemble de mise en tension (42, 142) assorti d'un élément d'amortissement (140) et/ou d'un élément de stabilisation (138). L'ensemble de mise en tension présente des premier et second éléments de mise en tension (42) ayant chacun une surface de contact qui vient en contact avec l'élément de transmission (135), et une pièce de positionnement (142, 144) destinée à assujettir les éléments de mise en tension (42) à une certaine distance l'un de l'autre en vue d'appliquer à l'élément de transmission (135) une force de mise en tension appropriée. L'élément d'amortissement (140) est relié à l'ensemble de mise en tension (42, 142) et convient pour amortir les vibrations et oscillations du dispositif de mise en tension pendant le fonctionnement. L'élément d'amortissement (140) comporte un matériau amortisseur (154). L'élément de stabilisation (138) est relié à la pièce de positionnement (142, 144) et produit un couple de stabilisation qui est sensiblement égal et opposé au couple gyroscopique créé par les éléments de mise en tension (42) pendant le fonctionnement. Un mode préféré de réalisation de l'élément de stabilisation (138) est un élément contrarotatif (138) présentant une surface de contact contrarotative. La rotation de l'élément contrarotatif (138) est engendrée par contact de la surface de contact contrarotative avec la surface de contact d'un élément de mise en tension (42) ou avec une surface de l'élément de transmission (135). L'élément d'amortissement (140) se prête à un emploi avec un dispositif de mise en tension possédant des éléments de mise en tension pourvus de surfaces de contact qui sont fixes par rapport aux éléments de mise en tension respectifs.

Abstract: Selon la technique d'intégration à l'échelle de la tranche, appelée WSI d'après les initiales de l'appellation anglaise, des puces (C1-C16) pré-testées sont montées et connectées sur une tranche pré-câblée (W). On utilise surtout le silicium comme substrat de la tranche, étant donné qu'il est ainsi possible de câbler la tranche de manière économique selon un procédé multicouche standard. La conductivité d'un tel micro-cablâge de la tranche interdit toutefois l'utilisation de longues lignes d'alimentation dans le cas de longs cycles, de sorte qu'il faut introduire des circuits d'attaque intermédiaires (Tr1-Tr4). A cet effet, on a utilisé jusqu'à aujourd'hui des puces d'attaque séparées qui doivent être placées, connectées et testées, outre les puces fonctionnelles proprement dites. Selon le système WSI décrit, les circuits d'attaque intermédiaires ne constituent pas des puces séparées, mais sont réalisés sur les puces fonctionnelles elles-mêmes.

Abstract: Bearing cag es consist of a comb-shaped part and a cover disc. The method and the apparatus have the following features: an annular block, the mass of which is greater than the mass of the comb-shaped part which is to be shaped, is introduced into the block-receiving opening (15a, 15b) of a die (12). During extrusion with a ram (6), the block material is extruded forwards into the cavities (14) of the die (12), in which the webs of the comb-shaped part are formed. The material continues to be pressed, the excess material being removed by backwards extrusion. This excess flows out of the die (12) through a gap between the sidewalls of the upper part (15a) of the block-receiving opening and the lower part (6a) of the ram (6). The cavities (13) which serve for the shaping of rivet spigots at the ends of webs of the comb-shaped part are also filled with material. <IMAGE>
