Abstract: L'invention concerne une vanne comprenant un conduit d'entrée et un conduit de sortie. En vue d'obtenir une vanne, en particulier pour usage médical, pouvant être fabriquée économiquement sous forme d'un article à jeter, et pouvant être commandée aussi bien manuellement que par l'intermédiaire d'une pompe, l'invention est caractérisée en ce qu'il est prévu un élément de rappel réversible en un matériau élastique interrompant l'écoulement du fluide du conduit d'entrée vers le conduit de sortie en l'état de non-fonctionnement et autorisant cet écoulement, lorsqu'une pression axiale est exercée sur la face extérieure de l'élément de rappel, opposée au fluide circulant dans la vanne, en libérant une ouverture disposée axialement par rapport audit élément de rappel. On obtient ainsi une vanne de construction simple autorisant le passage d'un fluide par simple application d'une pression sur la face extérieure de l'élément de rappel.

Abstract: L'invention concerne un dispositif et un procédé de brasage par faisceau laser, notamment de brasage fort par faisceau laser. Dans le brasage par faisceau laser, la position relative mutuelle du foyer laser, du fil et du joint de brasage est déterminante pour obtenir des résultats de haute qualité. Dans les têtes de façonnage connues, la position relative est obtenue à l'aide d'un mécanisme au niveau du guide-fil et/ou par ajustement adaptatif du faisceau. Le dispositif proposé est un dispositif mobile qui permet de positionner le foyer laser indépendamment de la tête de façonnage et par conséquent également indépendamment de la position du fil (1) et de la trajectoire de façonnage. A cet effet, il est prévu d'utiliser des dispositifs à déplacement linéaire (13) et (14) qui déplacent la lentille de focalisation (5) et par conséquent simultanément le foyer laser par rapport à la tête de façonnage. Ledit dispositif permet d'effectuer un ajustement très précis de la position relative entre le fil (1) et le foyer laser ou peut être utilisé avec des mécanismes de commande par moteur sur des dispositifs à déplacement linéaire (13) et (14), dans un circuit de réglage et de régulation.

Title: Stepless variable chain transmission - has two fixed and two movable chain wheels carried on carrier with endless chain
Inventor: GRUB WALTER
IPC: F16H9/26
Filed: 1973-11-20
Abstract: The endless chain rotates about four chain wheels carried on a carrier. Two of the chain wheels are fixed position and the other two are correspondingly movable away from the centre of the carrier, thereby defining a variable gearing dependent on the spacing of the chain wheels from the centre of the carrier. Displacement of the other two chain wheels is achieved by a push pull lever which effects axial movement of a sliding dog which cooperates with a spiral toothed gear to rotate a spiral gear and a meshing gear. The meshing gear moves around the periphery of the spur gear thereby altering the position of the associated chain wheel.
