Title: Low relief polyester mouldings with sprayed metallic coatings - made using sealant between the cast polyester and the surface
IPC: B29C70/02
Filed: 1974-07-03
Abstract: Low relief sculptured mouldings with a metallic skin on a reinforced polyester resin support, made by coating a mould with a light varnish to anchor a dressing of metallic particles applied by spraying, then coating the rear of the metallic particles with a secondary varnish which seals the interstitial pores without either penetrating the metallic layer or fully submerging the protuberances of the uppermost particles. The layer of polyester resin reinforced with glass fibres is then built up on the sealed face and cured. Seal varnish prevents the low viscosity polyester precursor resins from permeating the sprayed metallic coating and thus staining the moulding surfaces and/or fouling the mould.

Title: Ski safety fixing with separable sole plate - permits easy replacement of sole plate on ski with springs retaining sole plate
IPC: A63C9/00
Filed: 1975-01-28
Abstract: The ski (2) carries a central boss (4) which fits in an elongated hole (3) in the sole plate (1). The sole plate (1) has a rounded end (5) which is held in place by the bracket (7). The heel-piece (14) of the sole plate (1) is retained by a spring-loaded plunger (10).

The sole plate (1) is easily replaced by placing it on the ski (2) so that the spring plunger (10) fits in the groove (16). The sole plate (1) is then snapped home by pressing on the bracket (9) so that the end (5) is forced past the ramp (21).
Patent FR-2311276-A1 (FR)
Title: Positional variation measurement device - has coreless coils supplied with HF voltage for large rapid movement detection
IPC: G01D5/22
Filed: 1975-05-12
Abstract: The device for the measurement of positional variation produces a voltage, e.g. a dc voltage, proportional to the linear motion of the object over the region of interest. The device can cope with rapid large movements without the necessity of an iron core for the flat measurement coils, which are mounted essentially opposite each other, by varying the coupling between the coils using a metal screen (16) moving between them. A higher operating frequency is made possible, a high frequency voltage being supplied to the exciter coil (12) from a generator (11). The screen (16) is attached to the object whose movement is to be measured. The other flat coil (15) acts as a secondary winding driving a suitable measuring circuit (18) whose output voltage represents the position.

A photocelll (3) receive light from a lamp (4) when the pointer is disturbed. The photocell output is then applied to the trigger (5) of a thyristor (6) in an alarm circuit.
Patent FR-2328828-A1 (FR)
Title: Safety mechanism to prevent forcing of locks - comprises sprung pivoting disc which releases pin and immobilises bolt
IPC: E05B65/00
Filed: 1975-10-20
Abstract: The mechanism consists of a disc (21) which is able to pivot inside the lock-casing. In its normal position, it lies parallel to the front surface (12) of the lock and is held in position by a spring (33). If an attempt is made to force the lock using some kind of tool, pressure exerted on the disc (21) causes it to pivot against the action of the spring. During this movement, a pin (28) is released which holds the disc in such a way that the bolt of the lock is immobilised.

The design allows the cups to be stored in stacks, occupying the minimum amount of space.
Patent FR-2333130-A1 (FR)
Title: Fuel injection pump for IC engine - has pressure relief valves to reduce pressure fluctuations in supply pipes
Inventor: CAMENEN JEAN-LUC
IPC: F02M55/04
Filed: 1975-11-27
Abstract: The fuel supply to an internal combustion engine is supplied through the pipe (21) and the fitting (24) to the injection pump (11). The upward motion of the piston (14) forces fuel at a pressure of 1000kg/cm2into the chamber (18). When the shoulders (15, 16) of the piston (14) come into line with the ports (20, 22) this high pressure is suddenly transmitted to the inlet pipe (22) and drain pipe (23). To prevent these high pressure fluctuations causing damage to the pipes (22, 23) the fittings (24, 25) are provided with spring loaded ball valves (26, 31) which limit the maximum pressure to a pre-determined value. Any surplus fuel returns to the fuel tank through the pipes (39, 40).
Patent FR-2296099-A1 (FR)
Title: Spark-ignition engine ancillaries for better timing control - increase engine braking with reduced carbon monoxide emission
IPC: F02D9/02
Filed: 1975-12-24
Abstract: The equipment is for an engine with a carburettor utilising a butterfly valve (20). A pressure tapping (66) just downstream of the valve in its idling position applies a vacuum of small throttle openings and low engine speeds to one side (82) of a diaphragm (76) which rotates the contact-breaker so as to retard the ignition timing. At a certain threshold speed, solenoids (96 and 108) operate two slides valves (88 and 100), one of which applies a vacuum produced at large throttle openings at another tapping (64) in the carburettor to the other side of the diaphragm (76) to advance the ignition timing. If the throttle control is released at speeds above the threshold, vacuum is derived from a further inlet tapping (50) via a pre-loaded valve which now retards the ignition and slightly opens the butterfly valve; this provides engine braking torque.
Patent FR-2336149-A1 (FR)
Title: Static exercise bicycle with oscillating handlebar - has links engaging behind fixed bar to prevent oscillation by cam
IPC: A63B23/04
Filed: 1975-12-24
Abstract: The static exercising machine has oscillating handle bars, enables exercise to be taken in a confined space, and extends the usual leg exercise to include the trunk. The machine constitutes a floor mounted chassis (15) bearing respectively fixed and articulating saddle (2) and handle bar (8) support columns (1, 7). The handle bar column (7) supports the pedal axle (14) and a polygonally profiled disc (11) which acts on a chassis fixed roller (3) to impart handle bar column oscillation. Two rod linkage systems (6) running longitudinally down the handle bar column (7) enable the handle bar column to be locked against oscillation by engaging the end of a link between the column and a transverse bar (6) on the chassis. A lever (14) adjustable spring (12) restrains the lower handle bar column end, enabling effort required to move the column to be varied, the machine requiring a rowing type action to manoeuvre the handle bars.

Title: Liquid treatment e.g. sizing of warp yarn layer - by sepg. into two layers before passing through liq. bath and then recombining
Inventor: NEVEUX J
IPC: D06B23/06
Filed: 1976-09-17
Abstract: A warp layer of high density parallel yarns being fed horizontally is liquid treated by being sepd. into two separate layers which are advanced essentially vertically in a treatment bath. The separate layers pass around identical guide arrangements and after liq. treatment are recombined into a single warp layer and wound up in conventional manner. Method is used for applying size or size and dye to high density yarns e.g. 835 Dtex being fed in a warp of e.g. 45 yarns/cm. The yarns can be kept well sepd. after the liq. treatment to reduce the risk of them sticking together as the size dries.

Title: Photosensitive film guide channel in developing process - comprises two parallel plates with antiphase sinusoidal slots providing support
IPC: G03B1/44
Filed: 1977-01-18
Abstract: A thin and flexible film with a photosensitive coating slides between two guides which give longitudinal rigidity for the film in an automatic developing process. This reduces undesirable deformation effects received when the film is wound on a bobbin. A guide for a film (3) comprises two parallel plates (1a, 1b) in which guide slots (2a, 2b) are cut. The edges (3a, 3b) of the film thus give longitudinal rigidity to the film. The plates are spaced at approximately the width of the film. The slots have a sinusoidal form in the longitudinal direction and one is in phase opposition to the other. Amplitude and wavelength are chosen to produce negligible deformation in the transverse direction.
