Patent FR-2004624-A1 (FR)
Title: Distributing apparatus
IPC: B05B1/30
Filed: 1969-02-26
Abstract: An apparatus is provided for distributing fluid material and more particularly one which makes it possible for the user to select different means of distribution and different kinds of material, for example, different kinds of paints. It consists of a source of the fluid material, means for distributing it, a first pipe for carrying the fluid from source to distributor head, a source of fluid propulsion under pressure, a second pipe connecting the propulsion source to the fluid material source so as to circulate it towards the distribution means and a valves for controlling the rate of flow of fluid through the first pipe. This valve provides a fine control of the distribution and consists of a body enclosing a cylindrical dowel and pierced by a channel, an intermediate part of which intersects the cylindrical dowel. There is also a piston pierced by a transverse opening which adjusts itself to rotate in the dowel in which it moves axially. It has a primary axial position in which it blocks the intermediate part of the channel so as to close the valve independently of its angular position and it has means of moving the piston into this position. It can also be displaced axially to a second axial position against the force exerted by the piston-moving means and can be rotated, in this second position to open the valve in a variable controlled manner.

Title: Hydro-electric water screen cleaning rake - fully automated with inexpensive positive drive
IPC: E02B8/02
Filed: 1973-03-29
Abstract: Motorised cleaning rake is for removing weeds and other rubbish from the spaces between parallel bars of a grill used to screen the intake water to a hydro-electric plant. The rake has teeth which comb between the grill bars with a linear movement effected by the towing action of a flexible band, e.g. a metal strip, being wound onto a winch drum which may be driven by a geared motor. The rake can be made self-cleaning by extending its working stroke so that the rake teeth are cleaned out by teeth of a stationary comb. The winch drum is a more positive drive than friction rollers and less costly than a rack and pinion.

Patent FR-2236102-A1 (FR)
Title: Hydraulic or pneumatic power switch control valve - contains medium channel extending parallel to actuating section of rotary part
IPC: F16K11/074
Filed: 1974-06-25
Abstract: A channel extends parallel to the rotary axis of the actuating section. The dimensions of this section, in direction of the axis, are small in relation to the other surrounding dimensions. The section may be shaped as a disc, held by ball bearings at its edge, and moved by an electro-dynamic drive. Movable hollow cylinders contact the section as sealing elements, and are subjected to a constant spring pressure. When a pressure medium is present, an additional force acts on the seals. The drive for the disc motion has a capacitor discharging via a coil, which causes the disc to rotate approx. through 70 deg.
Patent FR-2277215-A1 (FR)
Title: Burglar alarm incorporated in door lock - has circuit contacts closed when foam compressed if lock pivoted by lock picker
IPC: E05B45/06
Filed: 1974-07-04
Abstract: A bolt (4) is fixed by any appropriate means to the door (1) and, when in the locked position, the latch (5) enters an opening (6) in the inner wall (8) of a casing (7). The casing is fixed in place by at least four screws (9) on its upper and lower parts and by a further two screws which are inserted through the extended wall (8) of the casing, the extended wall being sunk into a groove (8b) in the door frame. If an attempt is made to force the lock by inserting a lever between the frame and the door, the door moves and the latch (5) tilts upwards, thus compressing cellular insulating material (14) and thereby connecting the two contacts (15, 15a) to complete the alarm circuit.
Patent FR-2237670-A1 (FR)
Title: Two stage gas stream dust separation - having inner cyclone and outer filter sleeves
IPC: B01D50/00
Filed: 1974-07-16
Abstract: Separator to remove dust from gas streams has a central cyclone unit with a tangential inlet branch. The centrifugal action causes the bulk of the dust to fall down the leg of a cyclone into a collector. The air passes up through a central shaft into a mantle and then flows down the inside of tubular filter sleeves. Cleaned air passes out into the shell of the separator and is exhausted by a fan. For separating dust from dust laden air e.g. in rock drilling.

Title: Washing machine control - providing partial pump-out of hot dirty wash water and refilling with clean water
IPC: D06F34/08
Filed: 1974-09-26
Abstract: In the control of a washing machine, partic. a machine for household use, at the end of the washing phase in which the wash water is pumped away from the wash drum, at least once, only a part of the water in the wash drum is pumped away and clean water is supplied in its place. More esp. the drum is filled with clean water each time after partial pumping out takes place. By carrying out the partial pumping out of the used wash water and refilling with clear cold water, a pre-selected number of times, the articles being wahed can be cooled gradually rather than being subjected to possibly deleterious 'thermal shock'.

Title: Lamp unit for night fishing - has generator and alternator supplying three lamps providing alternate light and shaded a eas to attract fish
IPC: A01K75/02
Filed: 1975-06-20
Abstract: The lamp unit uses a diesel generator to drive an alternator and provide electricity for three high pressure sodium vapour lamps. These are suspended over the stern of the boat, using a cantilever bracket. Each lamp faces outwards at 120 deg. intervals and is fitted with a reflector which brilliantly illuminates an area. These areas alternate with shaded areas and that under the lamp also provides shade. Fish are attracted by the lights and move towards them. When this becomes too bright they pass into the shaded areas and then move under the lamp and the boat itself for easier catching.

Title: Hot water central heating system - has small dia. copper pipes with flow and return within common casing
IPC: F24H9/12
Filed: 1975-11-07

Title: Pneumatic radial ply tyre has single ply - of reinforcing cords alternating with weaker filler cords
Inventor: GREINER HENRI
IPC: B60C9/08
Filed: 1975-12-31
Abstract: Pneumatic radial tyre has a single ply of cords comprising reinforcing cords alternating with filler cords. The reinforcing cords have dia. 0.5-2 mm and a resistance to rupture 50-300 Kgm.

Patent FR-2300495-A1 (FR)
IPC: A01C17/00
Filed: 1976-02-13
Abstract: The fertiliser broadcaster possesses a supply container (1) with agitator (7) and outlet orifice (3) and, underneath it, a centrifugal disc (4). Located above the supply container is a liquid container (10), from which liquid is supplied to the agitator via a regulating valve (16), in order to moisten the spreading material. In order to achieve a uniform supply of liquid and therefore a regular distribution of the spreading material, the liquid container (10) is closed off in an airtight manner and a pipeline (20) opens at the bottom into the liquid container, the inflow orifice (21) of which is located above the maximum possible liquid level. As the liquid flows off from the container (10), outside air is sucked in through the pipeline (20). The pressure exerted on the outflowing liquid consequently remains constant until the container is virtually empty.

Title: Electromagnetic windscreen washer pump - has magnetic piston moved along bore by energising solenoid coil
IPC: F04B17/04
Filed: 1976-03-03
Abstract: The windscreen washer pump (22) is operated electromagnetically by a solenoid coil. It comprises an outer casing fitting inside the liquid container (10) its suction orifice (42) communicating with it. The bore (32) of the pump is non-magnetic and holds the piston (38), this being a rod of magnetic material lying in the lower part (40). Around the upper part is the solenoid coil (50) which pulls the piston upwards when energised by an electrical impulse. The liquid in the bore is displaced through the outlet chamber (54), past a non-return valve (44). The piston strikes a buffer spring (52) and is returned by gravity, suction refilling the bore.
