Patent FR-2269980-A1 (FR)
Title: Swimming flipper with foot pocket - has flexible flaps in rigid part of pocket extension
IPC: A63B31/11
Filed: 1974-05-09
Abstract: Each flipper comprises a pocket (1) fitting over the foot and extended to form an enlarged flattened area. The outermost part (6) of this is flexible whilst the part nearest the pocket is essentially rigid. In this part are two elongated flaps (2, 3), each being flexible about the side (4, 5) attached to the fliper. These flaps cover openings in the flipper, and increase the flexibility and effective propulsive surface of this area. On the down stroke, the flaps cover the openings; on the up stroke, each flap opens, contributing to the propulsive effort. Water flowing through the openings reduces the resistance encountered.
Patent FR-2288565-A1 (FR)
Title: Central vacuum installation for large buildings - has secondary pipes to outlets arranged in closed ring circuit for cleaning purposes
IPC: B08B5/04
Filed: 1974-09-02
Abstract: A central cleaning plant contains a blower to produce a vacuum and cyclone separators from which dust is collected in a vessel. A main collecting pipe runs from the cyclone inlet up the building and terminates in a regulator which maintains the suction pressure constant regardless of how many outlets are in use. At each level secondary pipes branch from the main pipe and run round their respective floors. They carry outlets to which portable vacuum pipes with nozzle can be attached. The secondary pipes are continued round their floors to form closed loops starting and finishing at the same point on the main pipe. This enables the secondary pipes to smaller without reduction in the capacity at each outlet.

Title: Slide track with balls for vehicle seat - has U-sections with edges bent over to lock together
Inventor: CHEYNET PIERRE MARIE OCTAVE
IPC: B60N2/07
Filed: 1974-10-01
Abstract: The track is particularly for the adjustment of vehicles seats, and comprises a lower U-section (1) fixed to the body work and receiving an inverted U-section fixed to the seat. Relative sliding between the sections is eased by a series of balls. The edges of the two vertical arms (5) of one (1) of the setions are bent over inwards through 180 deg. and those of the other section (2) are bent over outwards through the same angle. Thus the edges (11) of the lower section fit inside the edges (7) of the other section (2). Races can be formed for the balls (3) in the lower portion, while the faces of the upper portion which bear against them can be inclined so as to thrust the balls outwards.

Title: Spraying wheel for abrasive materials - has wear-resisting parts and is used for spraying barbotine into a drying tower
IPC: B24C5/06
Filed: 1974-10-14
Abstract: The spraying wheel, or rotary multiple nozzle, is for spraying materials which are highly abrasive, esp. barbotine or a slip used in the mfr. of ceramic articles. The hollow wheel consists of a base with a ring wall and an annular disc is used to bolt the ring wall to the base, the disc leaving an annular gap through which the ceramic slip can be fed. A row of nozzles, made in a wear-resistant material, is mounted round the entire periphery of the ring wall in radial directions w.r.t. the axis of the wheel, and the ring wall consists of two concentric rings. The inner ring is pref. made of a low-tensile steel, a synthetic material or rubber. Used for spraying ceramic suspensions into a drying tower. Gives improved wear resistance of the ring wall and easy replacement of all parts.

Title: Device for synchronising quartz oscillator to RF wave - has second oscillator to synchronise signal compared with oscillator signal
IPC: G04R40/02
Filed: 1974-11-28
Abstract: The device for synchronising a quartz oscillator to a stabilised radiofrequency analogue amplitude modulation or numerical phase modulation processes first and second signals whose frequencies are equal. The first signal is synchronised by the radio-frequency wave and the other by the controlled oscillator. A phase comparator which receives the first and second signals delivers a phase shift signal to a correction control input such that the level of the phase shift signal remains between predetermined limits. The signal synchronised by the radio frequency wave is processed by an auxiliary oscillator synchronised with the radio frequency wave.

Title: Fishing lure with detachable body - has bar with central and end hooks slidable in groove in body
IPC: A01K85/16
Filed: 1974-12-10
Abstract: The lure consists of a body (1) with a plate (2). A bar (3) slides in a longitudinal groove (4) in the lower part of the body, from which it can be removed by shaking. The bar has a central hook (5a) and an end hook (5b). Plate (2) has an aperture (6) through which the bar, attached to the line (8) by eye (7), may pass. When the fish is hooked, it attempts to free itself and causes bar (3) to slide in groove (4), freeing the body so that it is not damaged or swallowed by the fish, but retaining it on the line. If desired the body can then be slid off plate (2), by means of grooves (13a, 13b) and replaced by another body of a different colour or shaped as required.

Title: Measurement of postal envelope weight - uses balance whose movement is detected by movement of moire interference fringes
IPC: G01G19/00
Filed: 1977-03-22
Abstract: Weight of postal envelopes is measured rapidly by a weighing machine in which the moving weighing structure produces a parallel movement and comprises two parallel blade springs spaced vertically. Movement is detected by sensing movement of interference fringes. Envelopes for weighing enter a weighing platform (22, 24) to cause movement of a moving system (54) positioned between two arms (40, 42) of a transducer (36). Two blade springs prevent lateral movement thus producing parallel movement relative to a fixed system (46). A condenser lens (60) is located between a lamp (64) and the moving system which causes movement of interference fringes. These are detected by photodetectors (72) in an isolating disc (76) and produce mass measurement information.

Title: Separation of air from liquid before a centrifugal pump - a chamber being attached to the pump to collect the air
IPC: B01D19/00
Filed: 1977-10-04
Abstract: The pump consists of a turbine rotating within a housing of which the centre is pierced by a liq. inlet, the outlet being at the bottom. The air separating appts. comprises a chamber separated into two compartments by a wall extending upwards from the bottom of the chamber, the two compartments communicating with each other at the top of the chamber.
