A final brushing operation is pref. effected on the pile by brush rollers and the fabric passes over a heated roll between the preliminary and final brushing operations to produce a sheen on the fabric. Wear on the preliminary brushing rolls is reduced thereby increasing their working lives.
Patent FR-2234973-A1 (FR)
Title: Casting large filled epoxy resin mouldings under vacuum - using a cascade between two funnels to devolatilise the resin
IPC: B29C39/42
Filed: 1973-06-28
Abstract: Mouldings are made by mixing an epoxy resin with all required fillers, catalysts, etc. at ambient pressure and any optimum temp. and then admitting the fluid mixt. from a funnel fitted with a mushroom valve into an evacuated autoclave contg. a mobile mould. The resin mixt. falls freely into a funnel on an opening in the mould inside the autoclave. Esp. suitable for mfr. of large, void free mouldings for e.g. electrical power distribution components. Mixing at atmospheric pressure avoids emulsification which tends to occur if mixing is effected under vacuum, and which inhibits subsequent degassing. Degassing from a falling liq. film. is more efficient than degassing from a bulk resin placed under vaccuum after casting.
Patent FR-2235157-A1 (FR)
Title: Thermoplastic foam prodn. by volatilisation - of impregnated liquid which is nonsolvent for plastic and contains water

Title: Fixed exercise bicycle with effort indicator - pedals operate a dynamo whose output is measured by transforming into heat
IPC: A61B5/22
Filed: 1973-10-16
Abstract: The therapeutic bicycle on adjustable length lever arms has pedals (13). The axle (30) carries a gear wheel (1) which drives a dynamo (11) by means of a chain to another gear wheel (2), a pulley (12) and a belt (4). Tension of the belt (4) is maintained by the weight of the dynamo (11), hinged about a pin (6). The various devices are mounted on a light alloy base (3) fixed onto a steel tube frame with a tube (9) for the saddle. The dynamo (11) generates an electric current which flows through an electric resistance. The heat dissipated by the resistance gives a measure of the effort exerted by the feet of the patient onto the pedals (13). A regular check of the progress of the patient can be made by this bicycle.
Patent FR-2243076-A1 (FR)
Title: Trailer vehicle in which grapes are pressed - using screw worms and twin rollers while waste is shed during transport
IPC: B30B9/16
Filed: 1973-11-27

Patent FR-2260724-A1 (FR)
Title: Brake lining wear warning system - has wire embedded in friction lining making contact when exposed by wear
IPC: F16D66/02
Filed: 1974-02-13
Abstract: The steel brake lining support (1) is provided with an indentation (11) shaped as required to fit the detector wire (3). This indentation improves the mechanical integrity of the support-lining-detector wire system. After bonding or moulding the lining (2) to the support, a hole is drilled, parallel to the indentation to take the insulated (31) wire which is held in place by polymerisation of the plastic (32). The wire is thus rigidly held in place and electrically isolated. When the lining wears down and exposes the wire, electrical contact is made and this actuates the thickness warning indicator. Various forms are described which have advantages of low production cost or high mechanical strength.

The rotor is enclosed in a duct (1) which has a tapering inlet running into a circular housing with an outlet (6). The tapered shape of the duct increases the velocity of the air as it impinges on the blades (5) and in addition the blades are shielded from the wind until they arrive at the position where they begin to move in the same direction as the wind. The rotor and duct assembly is mounted on a vertical spindle and provided with a vane to align itself to the wind.

Title: Stable emulsion prepn. from two immiscible liquids - by polymerisation of e.g. polyalkylene glycol diacrylate dissolved in dispersed oil phase, for lubricants, paints, etc.
Inventor: VAYSSIE MADELEINE
IPC: C09K23/00
Filed: 1975-09-19
Abstract: A stable emulsion comprising two immiscible liquid phases is prepd. by dissolving a polymerisable cpd. (I) in one liquid, (I) being insoluble in the second liquid and having surfactant properties with respect to both phases, mixing and then emulsifying the two phases and finally polymerising the emulsion. Polymsn. of (I) produces a polymer film around the emulsion droplets and prevents coalescence. The emulsion therefore has indefinite shelf life and is stable under mechanical stresses and shear.

Title: Control valve for pneumatic brakes - with interchangeable conical support surfaces to prevent damage
IPC: B60T8/18
Filed: 1975-10-17
Abstract: The control valve for the pneumatic braking system has the control element supported on the housing walls by a flexible membrane (13). The membrane is supported on the one side by a conical face (1) in the valve housing. The upper side of the membrane is likewise supported by a conical face, but this face is fitted as an insert (15) with the angle of the face chosen to fit the characteristics of the valve. The space between the membrane and the insert is connected to atmosphere by a venting line fitted with a filter pad (17). The support surfaces reduce any wear on the membrane which would shorten its effective life.
