Abstract: Heat sink for a network card of a compute blade, said compute blade comprising a cold plate wherein a cooling liquid circulates, said heat sink comprising a body comprising two main faces of which a so-called “hot” face and a so-called “cold” face, opposite said hot face, said cold face being configured to be interfaced with the cold plate, the hot face comprising at least one housing configured to receive at least one heat generating component of the network card.

Abstract: A liquid-cooled heat sink for a plurality of compute blade connectors, including an elongated shaped body defining on one of its faces a heat collection surface of the plurality of connectors. The heat collection surface includes a plurality of interfacing zones arranged consecutively along the heat collection surface, wherein each interfacing zone is configured to interface with a connector of the plurality of connectors in order to collect the heat, and wherein the heat sink includes at least one stiffener mounted on the body.

Abstract: Method for manufacturing a heat sink for liquid cooling system of a compute blade of a supercomputer, comprising in particular a friction-stir welding step of a base plate at a machined central rib and at a machined rim.

Abstract: A damper for an object is placed in a medium subjected to vibrations. The damper has an idle state in the absence of vibrations, a first operating state in case of vibrations of a first type, and a second operating state in case of vibrations of a second type. The level of each vibration of the first type is less than the level of each vibration of the second type. The damper includes an outer support structure, an inner support structure, and at least one pair of membranes formed of a first membrane and a second membrane. Each membrane is formed of a viscoelastic material including fibers aligned substantially in a same direction.

Abstract: A machine for producing metal die castings is disclosed and comprises a crucible that incorporates an injection pump assembly which is mounted in such a way as to clear the upper access of the crucible to facilitate cover sealing and removing. The crucible is located in a furnace and is reciprocable to move the injection barrel and nozzle to and from a mold. The injection barrel is immersed in the crucible beneath the level of the molten metal to enhance heat transfer between the barrel and injected metal. The separate plunger and shot assemblies are located in the pump body in a "V" configuration so that maintenance of these units can be carried out without exposing the top of the furnace to the atmosphere.

Abstract: Device for maneuvering large capacity bags filled with powdered or granular materials wherein a square 6 formed from four tubes 11-14 is placed on the bag, the cross-pieces 9 formed by the ends of the tubes being engaged in the straps 2-5 of the bag. The forks of a forklift truck can be inserted in two parallel tubes enabling the bag to be maneuvered without risk of overturning, without the truck driver leaving his seat and without the help of another person. Equipped with an annular accessory 18 forming a support for the funnel 21 of a bag 20 which can be locked onto the inner sides of the tubes so that is inscribed in the square, one of the major applications of the device according to the invention is the robotization of the emptying and filling of flexible containers.

Abstract: A machine for injection molding or die casting includes a main machine base with an injection unit mounted on the rear face and a mold guideway mounted on the front face. An aperture in the main machine base and a corresponding one in the base of the guideway provides for the nozzle of the injection unit to engage molds carried in the guideway. The reciprocating of the molds toward and away from one another is due to the action of a totally enclosed toggle assembly interconnecting mold-carrying shanks with compression lever brackets mounted in the ends of the guideway, actuators being located centrally of guideway ends and linked to the toggle assembly. Position adjusters are incorporated for adjusting the location of the injection unit on the rear of the machine to position its nozzle relative to the molds.

Abstract: A die casting machine has a frame with a base plate pivotally mounted thereon and supporting a furnace pot. A die assembly is mounted on the front face of the base plate and a double locking toggle arrangement is used to open and close the dies. The gooseneck assembly is mounted for linear movement to actuate the nozzle onto the die parting line.
