Patent EP-0480731-A1 (EP)
Inventor: WADE MALCOLM VICTOR
IPC: F16D35/00
Filed: 1991-10-10
Abstract: A start-up coupling engages progressively in two stages. During the first stage drive is transmitted from an input shaft (3) along respective paths (8,7,9,12,11,10,25 and 26; and, 19,20,19 and 32) to helically-toothed rollers ( 2 7 , 30 ) which mesh but are designed to be incapable of transmitting drive between them, or of doing so very inefficiently. The rollers (27,30) are mounted in an oil-filled chamber (18) in a casing (1) integral with an output shaft (2). During the first hydraulic stage of engagement, oil pockets between their oppositely-moving teeth (28,31) prevent them from engaging as the phase of one roller (27) is progressively changed by a centrifugal adjustment (4) against the bias of a torque cell (19). However, increasing frictional resistance in the oil pockets causes the rollers (27,30) to exert an increasing rotational torque on the casing (1). Simultaneously, the relative movement of the roller teeth diminishes to reduce the hydraulic pressure in the pockets to a level where the pockets collapse. This initiates the second stage of engagement when drive is transmitted through the coupling mechanically by way of rubbing of the roller teeth (28,31). This rubbing ceases when engagement of the coupling is completed. Tooth wear is lessened by the two stages of engagement.

Title: Feed-through for a lead terminal on the cover of an accumulator cell.
Inventor: BRINKMANN JUERGEN
IPC: H01M50/172
Filed: 1991-02-25
Abstract: In the feed-through disclosed, an annular sleeve (3) made of plastic material is attached to the shaft (1) of the terminal at the same height as the cell cover (6). The sleeve extends through the cover and is joined to it to form a seal between the two. The internal diameter of the sleeve is a defined amount larger than the external diameter of the terminal shaft which, in the vicinity of the sleeve, has at least two rectangular cross-section annular grooves (4) located a certain axial distance apart. Located in each groove is an O-ring (5) made of elastomeric material, the difference between the internal diameter of the sleeve and the radial depth and axial width of the grooves being chosen so that the O-rings are deformed from a circular cross-section to a cross-section with a shorter and a longer axis, thus pressing the O-rings against the grooves and the sleeves in four areas where the ring is flattened.

Title: Synthese fractionnaire de type n/m
Inventor: BLACK GREGORY R
IPC: H03L7/187
Filed: 1991-04-22
Abstract: Un synthétiseur de fréquence utilise un démultiplicateur de fréquence (103) et un multiplicateur de fréquence (403) dans la boucle de réaction. La séparation de fréquence minimale entre deux canaux synthétisés contigus est égale à la fréquence de référence divisée par le rapport de multiplication du multiplicateur. Le rapport de division du démultiplicateur de fréquence (103), qui peut être analysé comme étant la somme d'un nombre entier et d'une partie fractionnaire, est modifié dans le temps par une séquence numérique, ce qui se traduit par un incrément de fréquence minimal égal à une fraction de la fréquence de référence. Le multiplicateur (403) sert à réduire les non-linéarités du synthétiseur de fréquence lorsque la partie fractionnaire du rapport de division entraîne une variation importante du rapport de division instantané, en réduisant le rapport de division effectif de la boucle.

Abstract: Methods are provided for determining relations between autoimmune degenerative diseases and specific variable regions of T-cell receptors as associated with the host HLA or T-cells associated with combatting neoproliferative diseases. By identifying the particular T-cell receptors which cause or are the disease in mammals, various prophylactic and therapeutic techniques may be employed for inhibiting the attack of the T-cell receptors on the native protein or tissue enhancing the defense. In addition, individuals may be diagnosed as to their propensity for a particular autoimmune disease or the occurrence of such a disease.

Abstract: This invention provides shielded and wireless connectors for interconnecting electronic circuit boards that are stacked in metal carriers. Serial interconnectors through the carriers provide transmission line paths through the stacked layers through connector assemblies embedded in and fed through each carrier in collinear alignment with each other. Each of the embedded feed through connector assemblies has upper and lower button connectors interconnected by a metal conductor, all positions within an axial hole formed by a pair of substantially cylindrical dielectric inserts.

Abstract: Technique de traitement de tranches consistant à séparer une tranche extrêmement fine en une pluralité de puces complètes contenant des circuits sans avoir à manipuler directement la tranche. Dans un mode de réalisation, un substrat est aminci par formation d'une configuration de tranchées dans sa surface supérieure, la profondeur des tranchées étant de l'épaisseur voulue des puces. Une matière résistant au polissage est ensuite formée dans la tranchée, et applanie jusqu'à une couche de passivation du côté supérieur, laquelle est configurée pour exposer des régions de test de surface. Une fois la tranche testée à l'aide d'une sonde, ladite tranche est fixée face vers le bas sur une poignée de support au moyen d'une matière collante telle que de la cire. Le substrat est érodé sur son côté inférieur jusqu'à la matière d'arrêt se trouvant dans la tranchée, laissant une couche de tranche mince. La matière de tranchée est ensuite éliminée. Les puces individuelles sont séparées de la poignée de support par fusion de la cire. Dans un autre mode de réalisation, une couche de tranches minces est formée sur une couche d'oxyde en fuite. Après la configuration des tranchées et le montage à la cire face vers le bas, le substrat de support est poli jusqu'à la couche isolante enfouie. La couche d'oxyde enfouie est ensuite ôtée par gravure. Les puces sont retirées par chauffage de la cire. Dans un autre mode de réalisation, une matière résistant à la gravure est formée sur la couche de passivation et sur les parois latérales de la tranchée, une partie de plancher de la configuration de tranchée exposant l'oxyde enfoui. Un agent de gravure est ensuite appliqué à l'oxyde enfoui par l'intermédiaire de la partie de plancher exposée de la configuration de la tranchée, de manière à ôter par gravure l'oxyde enfoui, soulevant ainsi les puces du substrat de support.
