Abstract: L'invention concerne un échangeur de chaleur à plaques qui comprend une pile de plaques annulaires profilées de dimension et de forme similaires dont les faces avant et arrière se font face successivement. Les surfaces de l'échangeur de chaleur enfermées entre un bord plat intérieur et un bord plat extérieur présentent de préférence des profils ondulés. Les ondulations s'étendent en spirale et chacune d'elle prend naissance et se termine dans un plateau imprimé jusqu'au niveau des crêtes des ondulations. Un passage est ménagé à travers la plaque au centre de chaque plateau. Les plaques sont soudées ou brasées dans les endroits où elles sont en contact les unes avec les autres dans la pile. Une substance cédant de la chaleur est acheminée à l'échangeur de chaleur à plaques à partir de la périphérie et circule à travers ce dernier de façon radiale. Une substance absorbant de la chaleur circule à travers l'échangeur de chaleur dans le sens radial inverse et est acheminée et évacuée par l'intermédiaire de canalisations circulaires placées au niveau des faces. Une section de passage augmentant avec le rayon est ainsi destinée à la substance expansible absorbant de la chaleur, et une section de passage est prévue pour la substance cédant de la chaleur dont le volume diminue. Ceci permet de stabiliser l'écoulement et d'améliorer le transfert de chaleur. A la différence des réfrigérants à l'huile connus, un filtre n'est pas raccordé de façon axiale, mais disposé à la périphérie du boîtier. Le filtre présente ainsi une surface plus importante et une durée d'utilisation supérieure, et les contraintes dynamiques exercées sur l'échangeur de chaleur sont réduites.

Abstract: This is regarding a type of device aimed at a simpler, in relation to alrea dy existing techniques, endovascular positioning of a stent-graft in the abdominal aorta for the therapy of aneurysms up to the point of its bifurcation. This device is comprised of a system of three cylinders: a "main" centrally place d and two "limbs" peripherally placed. Each of these cylinders has a central and a peripheral orifice. The cylinders are comprised of a cylindrical metallic skeleton which is self-expanding and made out of stainless steel or nitinol and which is externally covered with a cylinder made out of thin-layered PTFE, Dacron or some other elastic biocompatible material, refolded around th e peripheral orifice of the skeleton of the main cylinder. These cylinders can be compressed into small diameter tubules and enter the vascular lumen. Afte r their insertion into the desired position, they expand, regaining their original diameter. The main cylinder is placed inside the aorta becoming more circular when it comes in contact with the healthy part of the aorta central to the aneurysm at the center of the orifice. The peripheral orifice of the main cylinder sits upon the expanded aortic bifurcation. The two limbs have a central orifice with a diameter equal to or approximately about 2 mm smaller than the diameter of the peripheral orifice of the main cylinder. The branching of the main cylinder is accomplished by the entrance of the main ends of the two limbs inside the peripheral end of the main cylinder. Both limbs are at the same height in such a manner that they compress each other at the center of the cylinder. Each limb exerts equal pressure, whereas equal pressure is also exerted on the internal surface of the main cylinder from their externa l surface and together they both occupy at the height of their orifices the entire perimeter of the main cylinder. Alternatively, as limbs (peripher al cylinders), tubes of different diameters and types of skeletons can be used.

Title: Torque converter
Inventor: YOSHIMOTO TOKUJI
IPC: F16D33/18
Filed: 2000-11-08
Granted: 2004-12-21
Abstract: A torque converter includes a pump impeller, a turbine impeller, a stator impeller disposed between the pump impeller and the turbine impeller, and a free wheel which is interposed between the stator impeller and a stationary case and operable to lock the stator impeller in order to allow the stator impeller to bear a reaction force generated with the amplification of torque between the pump and turbine impellers. In this torque converter, a stator shaft connected to the stator impeller is disposed with its tip end being passed through a turbine shaft to protrude outside the turbine shaft. The free wheel is interposed between the tip end of the stator shaft and the stationary case. Thus, it is possible to reduce the diameter of the stator impeller and thus, the diameter of the entire torque converter, irrespective of the presence of the free wheel inhibiting the rotation of the stator impeller.
