Patent FR-2134191-A1 (FR)
Title: Drying powder - or granules, eg sand by passing over grille with suction pressure below
IPC: B01D21/00
Filed: 1971-04-26
Abstract: Granular or powdered materials, such as sand, crushed mineral ore, coal, sludge is dried after washing by being conveyed over a grille which has a sub-atmos pheric pressure maintained on the other side. The moisture content can be reduced to a degree suitable for storage transport or immediate use. The operation is continuous and is equally efficient as more expensive and sophisticated operations under-taken in centrifuging and vibratory equipment.

Title: Machine to form piles of fragile disc shaped objects - has rotary tables with guide holes and ramps and cam operated pushers
IPC: B65G57/32
Filed: 1974-05-03
Abstract: The apparatus builds piles of fragile disc shaped objects, and moves the piles to a subsequent operation. The machine comprises two tables (8, 9) driven in rotation by a motor (3) and gears (4, 5). The objects arrive on the top table and are guided by stationary ramps to holes (15) in the top table. The objects then pass down a ramp made of spring sections between two walls (13, 14) and are thus built into piles. When a pile reaches the required height an electrical contact operates an actuator (40) which raises a shaft (31) on a push rod (34) into engagement in cams (32, 33). The piles are pushed radially outwards on the lower table, and are then moved off the table by curved vertical wall of increasing radius.

Title: Rubber wall or floor tiles cut into segments - interlocking segments of different colour tiles form patterns
IPC: E04F13/18
Filed: 1974-07-02
Abstract: The rubber linoleum tiles are cut in an arc in such a way that a diagonal of the original square forms radii of this arc. These shapes are cut from red and black tiles and the black part of one (B') is laid with the red part of another tile (A') to form a two colour patterned square. In another form of the invention yellow and black square tiles are cut diagonally and halves of different colours are matched to form shapes such as arrows. The tiling system produces no wastage and large numbers of different cuts may be used.

Patent FR-2287029-A1 (FR)
Title: Detector for ferromagnetic objects - has coil movable in magnetic field in circuit rejecting mains interference
IPC: G01V3/08
Filed: 1974-10-02
Abstract: An inductive coil is connected in series with a transistor emitter circuit. The emitter current generates a magnetic field in the coil which is capacitively tuned to a low resonant frequency. Resistors in the base circuit permit adjustment of the current and provide thermal stabilisation for the transistor. A feedback capacitor and a capacitor coupled to a second transistor ensure that high frequencies are eliminated. A third transistor acts as a limitter while a fourth transistor provides an output for recording or indicating purposes.

Abstract: The system turns the containers through 90 deg. about their lengthwise axis, being particularly for use when sandblasting or painting the underside. A first hoist is coupled to the corner fittings at the top corners of the container, and a second one to the diagonally opposite bottom ones, the top and bottom corners concerned being at the same sides of the container. This is then lifted clear of the transporter truck, and manipulated by means of the two hoists until it has been turned through 90 deg., after which it is lowered onto the truck again.
Patent FR-2257822-A1 (FR)
Title: Cylindrical tension-compression spring - has cylindrical sections joined axially by spacers
IPC: F16F1/02
Filed: 1975-01-15
Abstract: The spring is composed of a series of short, thin walled, equal cylindrical rings (11, 12, 13) spaced axially by longitudinal forming pieces of the same thickness. The spacers are so arranged that there are an equal number between each pair of rings, and each spacer falls midway between those joining adjacent rings. Spring effect is given by the elastic deformation of the rings between spacers. The end rings are typically wider than the intermediate rings and the spacers can increase in width towards one end of the spring. The rings may be formed of short zig-zag lengths joined to spacers at the corners.

Title: Light waveguide with two or more fibres - is connected by truncated cone arrangement and with liquid included between fibre faces
Inventor: ROCTON LUCIEN
IPC: G02B6/255
Filed: 1975-02-14
Abstract: The light waveguide has at least two optical fibres (1, 2) linked by means of a connector, in which the end of one (1) or both of the two fibres forms a truncated cone (3) defining the front face of the connection. The truncated cone (3) may be formed on the fibre (1) positioned on the transmission side and, in this case, the small base (of the cone), having a diameter less than that of the fibre, constitutes the front face of the connection. Alternatively, the truncated cone may be formed on the fibre positioned on the reception side and, in this case, the large base(of the cone), having a diameter greater than that of the fibre, constitutes the front face of the connection. The waveguide may include a liquid (pref. polyisobutylene), whose refractive index is close to that of the fibre cone, between the front faces of the fibres.

A spacer of cardboard or plastics with a row of matching U-shaped slots is inserted into the block of pages. A second plastics strip provided with a row of spikes is pressed into position so that the spikes penetrate the holes. Heat is applied to bond the end of plastics spikes to the lower strip. The spacer is then removed, leaving a gap between the block of pages and the upper strip so that the pages lie flat.

Title: Recovery of perchloroethylene from exhaust of dry-cleaning machine - by cooling and washing, with a final filtration
Inventor: BLONDEL PIERRE
IPC: D06F43/08
Filed: 1975-09-12
Abstract: The solvent-charged air from the dry-cleaning machine enters the recovery appts. at a low level and p asses upwards, (a) first through a cooler at 0 degree C, then (b) through two near-freezing water sprays separated by a grid and finally (c) through a filter before returned to the dry-cleaning machine. The perchlorethylene condenses into droplets, which fall into the water at the bottom of the appts. Here they meet a sloping plate down which the solvent runs to collect at one side of the appts. while the water gravitates towards the other, a partition separates the two regions. When enough solvent has collected, it is runn off though a cock, the water, still at 0 degree C, is returned to the spray nozzles.

Title: Electrically fired safety missile fuse - has percussion charge carrier rotated into armed position and indicator projecting at rear
Inventor: SCHILLING MICHEL
IPC: F42C15/30
Filed: 1976-03-17
Abstract: The electrically fixed fuse is for the main charge (8) of a missile such as a rocket and incorporates a safety device protecting it from inadvertent firing either electrically or pyrotechnically. The percussion charge (1) is mounted at an angle, in a tubular carrier (2) held in a safe forward position by a shear pin (7). When the missile is fired, gases entering a chamber (5) in front of the carrier, force it back under pressure. At the same time, a pin (11) projecting from the housing (3) engages a curved groove (12) along the side of the carrier, rotating about its axis. This aligns the percussion cha*ge with an opening (8a) under the main charge (8). Two electrical contact pins (9) are inserted in corresponding openings (10) in a socket at the rear. A pin (14) is pushed backwards to project from the casing to indicate that the fuse is armed.
