Patent FR-2109018-A1 (FR)
Title: Chromium plating - accelerated by fast electrolyte circulation between electrodes
IPC: C25D5/08
Filed: 1970-10-30
Abstract: Electrolytic Cr-plating is carried out with the electrolyte being passed at a speed of 1-50 m/sec through the electrode gas and a current density of between 200 and 1200 A/dm2. The ratio between the electrolyte circulating speed and the current density is between 1:24 and 1:200. The contours of the workpiece cathode and the anode should be parallel so that a constant gap is formed for the electrolyte. The process is between 10-20 times faster, than conventional methods, and permits deposn. thicknesses of =200 mu m of improved hardness.

Title: Engine timing equipment - magnetic detector with electronic integrator circuit
IPC: F02P7/067
Filed: 1973-05-22
Abstract: Location of the precise angular position of a shaft is important in internal combustion engines, to determine when ignition should occur. In a distributor a cam shaft (4) with shaped teeth (31) is driven from the engine and rotates in the plane of a carrier plate (8) in which is located in a slot (9) for the operating arm of a vacuum pump.

Title: Elastic jointing sleeves mfr. on a removeable core - by inflating and freezing the sleeve to facilitate core entry
IPC: B29D23/00
Filed: 1973-11-07
Abstract: Elastic sleeves are mounted on a core, which can be removed to apply the sleeve on to a concentric cable joint etc. by prefabricating a fully vulcanised and elastic tube from natural or synthetic rubber; blocking the ends of the tube; inflating it to a bore of greater than the diameter of the core; and freezing the tube sufficiently to be able to cut it into individual sleeves and load prefabricated cores into the sleeves before the sleeve warms up sufficiently to partially relax back on the core. Sleeves may be combined with cores made by prefabricating a rigid extruded plastic tube and machining a relatively deep helical groove on or inside the tube. They are used for making joints by locating an oversize core supporting a prestretched sleeve to saddle a joint in e.g. a cable or hose, and progressively removing the core as a helical strip by pulling to develop a crack along the helical groove in the core. The elastic sleeve contracts to fit the joint as the core is removed.

Title: Detecting a change in the viscosity of moving fluid - by measuring the deformation of fixed element acted on by fluid
IPC: G01N11/10
Filed: 1974-01-07
Abstract: The change in viscosity of a fluid in a container moving under the action of e.g. an agitator is detected by measuring the deformation of fixed element due to the force exerted on the fixed element by the fluid. The method is used for e.g. detecting the polymerisation of styrene in the presence of rubber to determine the point at which processing operations should change. The method is more suitable for industrial use than using e.g. conventional viscometers.

Between the inner circumference of this washer and the pipe bore are elastically deformable, relatively soft, washers (9, 10) adjacent to the flange faces, and between these an annular spacer (8) with circular edges. As the bolts are lightened the grooves are forced into contact with the washers and these deform to counteract any surface irregularities in the pipe flange. The joint is useful for inflammable liquids or corrosive liquids and may be used withint a temperature range of -200 to 1600 deg.C. and up to a pressure to 10000 bars.

Secondary surface assembled on the panel are of stamped sheet metal with corrugations forming upward air passages between it and the panel, there being intervals between the corrugations to allow its mounting on the panel. The corrugations are so shaped that subsequent squeezing brings their sides closer together than at the base, where the interval occurs by which they are fixed to the panel. They can be closest to each other at a level near that of the crests after squeezing. After stamping, the sides of the corrugations can be parallel, their crests being roof-shaped, and the crests being flattened by squeezing.

Title: Stepping-switch arrangement for shell-type transformer - is in lateral projecting chamber of transformer housing with selectors level with taps
Inventor: KOCH ETIENNE
IPC: H01H9/00
Filed: 1974-07-11
Abstract: The arrangement for a stepping-switch for a three-phase shell-type transformer locates the selector above the selector load switch in such a way that the selector is on level with the taps of the winding. Selector and selector switch are located in a lateral projecting chamber attached to the tranformer housing. The load selector switch is withdrawable in a downward direction after the removal of a cover plate. The positioning of the selector switch reduces the copper wiring length resulting in copper savings and lessens the maintenance costs due to the smaller oil volume in the chamber.

Patent FR-2300884-A1 (FR)
Title: Temporary window sealing strip - has temporary protective sheath attaching to head and foot of one seal face and cantilevering over other
IPC: E06B7/23
Filed: 1975-02-12
Abstract: The sealing strip (1) with a temporary protective sheath (7), has a sheath which connects to the web type seal via hinges at the web base (12) and tip (13) to form rupture lines for eventual sheath removal. One face of the seal thus has a fixed sheath (7b), and an elastic cranked membrane (7a) catilevers over to cover the other face. The elastic nature of this latter section (7b) of the protective membrane permits its retraction to give tool access for the insertion of the seals shark toothed support base (3) in a woodwork mortice, and should the door require to be closed before sheath removal, the rupturing of the necked joint (12) between the membrane and the base obviates difficulties due to trapped air.
Patent FR-2302482-A1 (FR)
Title: Heater system using waste oil from engine sumps - includes tank sepg. heavier f impurities and circuit facilitating ignition
IPC: F23K5/20
Filed: 1975-02-26
Abstract: An arrangement for buring waste oil, esp. oil from the sumps of internal combustion engines, injected as a vapour into the hearth of a central heating boiler, has a vessel into which the crude oil is filled after having been filtered. In this vessel there are heaters positioned so that the flow of the crude oil is brought into their proximity the raising of the temp. of the oil resulting in the breaking up of the constituents of the mixt., and the settling out of suspensions of solid matter and of the water content as an emulsion. The oil phase rises to the surface of the fluid in the vessel which has a drain positioned at a point high enough from the bottom for the clean oil to be drawn off, as well as a vent for the sediment and the aqueous matter. A pump propels the oil through a heat exchange ensuring that the oil injected from the nozzle into the boiler hearth is at a high enough temp. The nozzle assembly has a byepass to a return line with a stop valve so that starting up is facilitated. The arrangement overcomes the difficulties of recovering spent lubricating oil contaminated with particles of metal, water, etc. and enables waste oil from engine sumps to be used 100% for central heating, hot air generators.
