Patent FR-2723048-B1 (FR)
Inventor: MATERNA PETER
IPC: B60R21/268
Filed: 1995-07-27
Granted: 1997-04-11
Abstract: A stored gas inflator is operable over a wide range of initial temperatures and such that the dependence of its total output as a function of initial temperature is substantially reduced. A vessel contains gas under pressure and has a seated outlet for the gas which is adapted to open upon command and permit passage of the gas therethrough. A thermal reservoir element is provided. A first exiting flowpath directs gas so that it substantially bypasses or avoids thermal contact with the thermal reservoir element. A second exiting flowpath directs whatever gas does not leave through the first exiting flowpath through the thermal reservoir element so that the gas has substantial thermal contact with the thermal reservoir element. A temperature-dependent flow control means varies the amount of gas passing through each of the aforementioned flowpaths.

Abstract: The module consists of a body (1) forming a compression chamber (3) which is fed with air under pressure. The chamber has an aperture (5) which is normally closed by an inner plate (6) connected to an outer flange (7). The body and the outer flange are connected respectively to two components of the robot. The module is equipped with an automatic rearming system in the form of a power cylinder (14-16) inside the outer flange and with its rod (17) passing through the inner plate (6) and interacting with the base (2) of the body. The power cylinder is fed constantly with a fluid under pressure so that its rod is held permanently against the base of the housing with a predetermined force, while the pressure chamber is fed with compressed air through a nozzle.

Abstract: The retaining element for a boot on a ski board comprises a body (3) which carries a retaining jaw with two webs (6,7). There is spring (14) housed in the body and a chain of connecting elements (6a,7a) between each web and spring such that the spring opposes outward displacement of either web. A vertically movable support plate supports part of the boot. A transmission connection activated by movement of the support plate modifies the return force the spring opposes to movement of each web. The transmission connection acts in a different way on the return force than that the spring exerts on each web. This results in the release threshold of one of the webs to be momentarily greater than that of the other web.

Title: METHOD FOR PROMOTING MAGNETIC PROPERTIES OF SINTERED NEODYMIUM-IRON-BORON (Nd-Fe-B) MAGNET
Inventor: SHUWEI ZHONG
IPC: C23C14/16
Filed: 2022-05-02
Granted: 2023-11-13
Abstract: A method for promoting magnetic properties of a sintered Nd-Fe-B magnet is provided. The method is suitable for sintered Nd-Fe-B magnets with various 5 components; the method includes: grain boundary repairing via a low-melting metal or alloy, grain boundary diffusion via a heavy rare earth element and the corresponding heat treatment process. In the present invention, low-melting properties of alloys are utilized to preferably diffuse and repair the discontinuous grain boundary rare earth phase on the surface layer of the magnet, thus obtaining a continuous low-melting rare 10 earth phase; the continuous low-melting rare earth phase serves as a rapid diffusion path for the heavy rare earth element to effectively promote the diffusion depth of the heavy rare earth element in the magnet and reduce the use amount of the heavy rare earth element, thus achieving the promotion in coercive force of the magnet. Therefore, the present invention has wide application prospects. 15
