Abstract: Levier muni d'un bouton (1) et d'une partie allongée (2). Le bouton est supporté à une des extrémités de la partie allongée (2) éloignée de l'extrémité reliée à un mécanisme devant être mis en action. Le bouton (1) qui comprend un interrupteur (14, 12), peut se déplacer radialement par rapport à l'axe longitudinal (3) de la partie du levier. Ledit bouton comprend également un creux (4) dans lequel déborde une extrémité (10) de ladite partie du levier (2). Le creux (4) présente une surface périphérique (11) définissant un espace vers la surface (12) de ladite extrémité de la partie du levier. Dans ledit espace est situé un élément de centrage annulaire élastique (13) butant, à sa périphérie externe, contre ladite surface périphérique de l'espace. A sa périphérie interne, ledit élément bute contre la surface (12) de la partie du levier et contre un élément de contact électrique annulaire (14). L'élément de contact fait partie de l'interrupteur connecté de façon fixe au bouton et apte à suivre celui-ci lors de ses mouvements radiaux. L'élément de centrage (13) a pour but de centrer l'élément de contact à la partie terminale (10) de la partie du levier. Lorsque le bouton est en position neutre, l'élément de contact mobile définit un espace vers la partie terminale de la partie du levier (la partie terminale étant inclue dans l'interrupteur en tant que deuxième élément de contact). Un mouvement du bouton, latéral par rapport à la partie du levier, et effectué manuellement, entraîne le déplacement de l'élément de contact annulaire vers une position excentrique où ledit élément se trouve en contact avec le deuxième élément de contact.

Abstract: PCT No. PCT/CH90/00266 Sec. 371 Date Jul. 23, 1991 Sec. 102(e) Date Jul. 23, 1991 PCT Filed Nov. 21, 1990 PCT Pub. No. WO91/08477 PCT Pub. Date Jun. 13, 1991.The apparatus of the invention has two heads each of which has three sensors for measuring the propagation speed of ultrasonic waves, the degree of moisture, and the temperature in a test material, in conjunction with a module having a microprocessor and memories. The microprocessor calculates the measured propagation speed of the ultrasonic waves. This speed is normed with respect to a set temperature (e.g., 20 DEG  C.) and a set value (e.g., 15%) of the degree of moisture. From these measurements, the microprocessor searches for the class of standardized mechanical properties in which the material falls. The microprocessor finds the class in which the value of the normed propagation speed falls in a table of values contained in one of the memories. The apparatus thereby enables the determination of the class of the material automatically and non-destructively.

Abstract: L'invention concerne un procédé de fabrication d'une prothèse dentaire ou encore la base pour une prothèse dentaire. Ici, la base est fraisée à partir d'un bloc de plastique en fonction de la topographie et du contour de l'intérieur de la bouche. La topographie et le contour de l'intérieur de la bouche peuvent être déterminés par une empreinte ou par un moyen optique ou par une combinaison des deux. Pour produire une empreinte, il est nécessaire d'utiliser un porte-empreinte, lui-même produit par fraisage en fonction de la topographie et du contour d'une empreinte d'origine. Le bloc plastique servant d'ébauche et une fixation de pièce sont conçus de telle façon que le bloc de plastique ne peut être admis qu'en une seule position dans la fixation de pièce.

Abstract: An apparatus and method for monitoring corrosion to members within the core of a nuclear reactor, particularly fuel rod cladding. A sensor means is submerged inside the core of a nuclear reactor near the member or fuel rods. The sensor means is comprised of a generally cylindrical section (24) having an outer surface that is subject to corrosion and radiation, and has a cross-sectional area A₁. The sensor means additionally has a reference section (15) subjected to radiation but not to corrosion, and having a cross-sectional area A₂. At least one pair of first probes (17c,17e), separated by a length L₁, is placed in electrical contact with the cylindrical section (24). At least one pair of second probes (17a,b) separated by a length L₂, is placed in electrical contact with the reference section (15). A current is passed throughout the sensor means to produce a potential gradient in the cylindrical section and reference section. The change in potential in the reference section, and the cylindrical section is measured and used to calculate the subsequent cross-sectional area in the cylindrical section between the first probes. Preferably, the cylindrical section and reference section are made from the same material as the member.

Abstract: In a magnetic resonance apparatus, a coil system is added to a gradient coil system, as a result of which a measuring field range can be adapted to the geometry of an object to be examined. For example, by addition of a Bo coil system to be activated simultaneously with the  z -gradient system, an asymmetry can be realized in the  z -gradient field, as a result of which return of disturbing resonance signals from an object part located outside the gradient field operating range can be avoided. Further, by addition of additional arc conductors, the  z -gradient linearity range may be displaced in the  z -direction.
