Patent FR-2316061-A1 (FR)
Title: Thermoplastic article with two moveable parts - formed by moulding parts separately using different plastics to prevent adhesion
Inventor: NOURY LOUIS ROBERT
IPC: A44B11/10
Filed: 1975-07-02
Abstract: Thermoplastic article having two relatively movable parts is formed by moulding the first part using a first thermoplastic and then moulding onto it the second part using a second thermoplastic. The second thermoplastic is selected so that it doesn't stick to the first thermoplastic and moulding of the second part is at a sufficiently low temp. that the first part doesn't melt. The method is used for moulding buckles used for garments or shoes. The moulding of a buckle is simplified and thereby cheaper as special bearing sockets for the tongue don't have to be used to prevent the tongue axle from sticking to the bearing housing of the surrounding frame.
Patent FR-2277860-A1 (FR)
Title: Spinning solns. of acrylonitrile copolymers contg. unsatd. sulphonates - rendered clear and colour-free by addn. of maleic acid
IPC: C08F220/44
Filed: 1975-07-10
Abstract: Spinning solns. contg. copolymers of acrylonitrile, unsatd. sulphonates such as allyl sulphonate and opt. other comonomers, made by soln. polymsn. of the monomers in DMF, are modified by the addn. of 0.01-1 wt % (on monomers + polymer) maleic acid. The maleic acid gives clear, cloud-free spinning solns. which give fault-free spinning over long periods with freedom from blockage of spinning nozzles, etc. The maleic acid may be added before the polymsn. or after removing the reaction mixt. from the polymsn reactor but before concn. The spinning soln. may also contain oxalic acid to bind Fe ions, to give fibres with a high degree of whiteness.
Patent FR-2320239-A1 (FR)
Title: Packing carton for wet fish - is fitted with convex base and drain holes to allow water to drain away
IPC: B65D5/00
Filed: 1975-08-05
Abstract: The carbon is made from two pieces of cardboard, one for the box and one for the lid. The box has a flat base, and the ends (2, 3) are extended into the flaps (7) which form the sides of the box. The sides are re-inforced by folding over the flap (4) on the outside and its extension (9) inwards. The slots in the side are cut to take the tongues on the outer edge on the flap extension (9). These tongues protrude vertically downwards below the base and give the base a central hump. This causes the melted ice in the carton to flow out through the drain hole (16).
Patent FR-2328160-A1 (FR)
Title: Double filament vehicle headlamp - has deflector above forward filament to guide beam through peripheral lens region
IPC: F21V13/00
Filed: 1975-10-17
Abstract: A vehicle headlamp ensures high light intensity for the undipped light beam. The dipped light intensity is not affected. The lamp filaments (22, 24) are arranged on the optical axis X of the reflector (12) on either side of its focal point (F). The reflector has collar (16) and screen (40) for deflecting light into a zone (30) in the upper part of the lens (18). Hence only reflected light from the undipped beam filament (24) is passed through this zone. The lens zone for this purpose can be smooth or it can have only shallow ridges. This zone ensures that light can reach its maximum distance.
Patent FR-2328611-A1 (FR)
Title: Aircraft arrester cable system - has two transverse cables forming part of endless loop with movable pulley blocks connected to energy absorption system
IPC: B64F1/02
Filed: 1975-10-24
Abstract: The two parallel transverse cables at approximately the same height above the landing strip (2) form part of a continuous loop of cable. The cable runs over fixed pulleys (3,4,5,6) on either side of the strip and the loop is then taken forward, parallel with the strip, to pass over a moving pulley block (7,8) on each side. A cable connects each of the moving blocks with an energy absorption unit (9,10) which may be of oil damped turbine vane type. The aircraft arrester hook thus has two chances of catching a wire and the distance moved by the damper cable is halved.
Patent FR-2329312-A1 (FR)
Title: Board game with football theme - has cards giving various playing manoeuvres used to move ball over squared surface
IPC: A63F3/00
Filed: 1975-11-03

Each player has eleven figures (3), representing a team and a small card (9) reproducing the playing area. A timer (10) controls the game and cards (6,7,8) are provided, these giving details of various playing manoeuvres used in full-size football. Each player selects several cards and uses these to manoeuvre his team and the ball in accordance with the instructions. Played cards are stacked in a box (5), other being selected to replace them.

Abstract: The sachet is used for infusing coffee and consists of two pieces of specially treated paper, of oval shape, joined round the edges. The sachet is filled with coffee powder and has a label attached indicating the type of coffee contained. The sachet is used by being placed in a cup and having hot water poured over it. A cord attached to the sachet is used to remove it.
Patent FR-2305903-A1 (FR)
Title: Closed circuit TV receiver - switches out audio channel when TV sync. signal is received
IPC: H04N5/60
Filed: 1976-03-25
Abstract: The closed circuit television receiver has a detector consisting of a coincidence circuit, a rectifier and a switch to switch on the audio channel when the television sync. signal is received. A demodulator in an IF stage only demodulates the IF signal when a carrier frequency is present that lies within a narrow region of the IF stage's passband. The IF stage is fed from an input stage with high cross modulation immunity. The audio channel is cut in only after the receiver is synchronised with the sync. signal. Switching out the audio channel when the receiver is not in use prevents the reception of other adjacent signals, e.g. police communications etc.
Patent FR-2307365-A1 (FR)
Title: Electromagnetic contactor with armature coupled guide - has two clamps connected to guide pressing armature against protrusion
IPC: H01H50/22
Filed: 1976-03-30
Abstract: The electromagnetic contactor has a magnetic system driving the moving contacts, whose moving armature is connected with a moving guide. For connection of the armature (3) and the guide (7) are provided clamps (4) connected to the guide and located on both sides of the armature. These clamps press the armature against a protrusion (7a) on the guide. Preferably on both sides of the armature is provided a shaped part (3a) with a holding surface (10) on which the clamps run up. In addition each clamp has typically a lug (9), reaching behind the shaped part of the armature and lifts the armature from the guide, when the clamps are swivelled into open position.

Title: Dentists drill with vibratory head - has piezoelectric wafer fitted to spindle to provide longitudinal vibrations and reduce heating effect
IPC: A61C1/07
Filed: 1976-04-14
Abstract: The dentist's drill is fitted with a vibratory head, longitudinal vibrations being supplied to the tool spindle by means of a piezo electric wafer (9). This wafer is connected into a source of alternating current. The head (1) of the drill has a right angle drive, transmitted through bevel gearing (4, 5) from a horizontal shaft (2) to the vertical spindle. This latter is supported in bearings at top (7) and bottom (8). The piezo electric wafer is in the form of a disc, fitted around the top bearing and contacting the spindle. The vibratory action reduces the heating effect of the tool and ensures freer cutting.
