Patent FR-2007615-A1 (FR)
IPC: B29C41/14
Filed: 1969-05-02
Abstract: 1,273,524. Moulding shoes. PORVAIR Ltd. 30 April, 1969 [1 May, 1968], No. 20737/68. Heading B5A. [Also in Division A3] Water vapour permeable, flexible, microporous three dimensionally shaped shoe uppers or upper components having resistance to loss of shape when heated are made by dip moulding a former into a mixture of a polymer extended in a liquid vehicle, e.g., a solvent, and coagulating the layer of polymer formed upon the former by a non-solvent for the polymer. The uniformity and size of the pores may be enhanced by incorporating removable particles of a filler, e.g., salt, in the extended polymer and removing the filler subsequently by means of the non-solvent, e.g., water, in the case of a salt filler. The non-solvent may contain a dye to be transferred into the dip moulded layer to colour it during the coagulating step. In one embodiment multi-layered polyurethane shoe uppers are made by dipping a hollow sintered polyethylene former into successive salt containing polymer mixtures, the former being covered with a reinforcing sock or toe reinforcement if desired. The former is withdrawn at different speeds to give regions of differing thickness if desired and the non-solvent may be applied by dipping in a bath, passing it into the interior of a hollow porous former, or both. The former may be made of wood, metal, for example wire gauge, solid or sintered plastics, or fabric and is internally supported if necessary. Where hollow, the interior of the former is preferably vented by a tube to the atmosphere to promote adhesion of the material to core.

Title: Heat exchanger module for several different coolants - esp. for gas liquefaction comprises one drum per coolant
IPC: F25J1/02
Filed: 1973-07-03
Abstract: A heat exchanger module comprises a number of parallel vessels or drums, integrally connected together as a unit, e.g., three in number, to permit a single warm fluid to be cooled by heat transfer from three different coolant paths passing through the three drums. Each drum is a plate heat exchanger with the plates extending transversely, the hot pass being across all three drums, while each drum operates as a flooded drum with respect to its refrigerant or coolant, which flows vertically. The hot and cold passes are sealed around the edges by rectangular strips, except for the hot fluid inlet and outlet, and cold fluid inlets and outlets. Used esp. in cascade cooling circuits, using different coolants such as propane, ethane, methane. A typical application is the liquiefying or natural gas.

Patent FR-2296114-A1 (FR)
Title: Hydraulic jack with double valve - uses magnetic force to position valve ball against one of two seats
IPC: F16K1/14
Filed: 1974-12-26
Abstract: The hydraulic jack transfers the oil via a double valve, allowing free flow from one side to the other or an increase in pressure by a ball bearing against one or other of the two valve seats. Magnetic fields are used to position the ball against a seat or in the central position allowing free fluid flow. Means are provided for shifting the jack piston into the position for oil transfer and also for raising the pressure on one or other side of the jack. There can be a cavity accommodating the ball in the central position so that it does not shift during fluid transfer, it being held in this position by a third magnetic force acting at right angles to the other two.
