Patent FR-2299537-A1 (FR)
IPC: F04D7/04
Filed: 1975-06-23
Abstract: The inlet port (6) of the centrifugal pump has a section which narrows in the direction towards the impeller (1). The impeller is open, at least on the inlet port side. The narrowing section ends in a circular edge which is positioned at a distance (l) upstream of the impeller (1). Downstream of this edge, the inlet port does not narrow any further. This design counteracts any accretion of fibres in the gap (5) between the impeller vanes (2) and the pump casing (4), so that the centrifugal pump is particularly suitable for fibre-containing liquids.

Title: Two stroke engine with fuel injection - has fan driven from torque converter to supply air to cylinders
IPC: F02B25/20
Filed: 1975-07-22
Abstract: The cylinder (10) of a two stroke engine is supplied with fuel from a tank pumped through the needle valve (23) by the pump (21). The needle valve (23) is controlled by the accelerator pedal (24). The fuel enters the cylinder (10) by the port (11) which is directly opposite the exhaust port (12). The fan (30) which supplies air through the ports (12, 13) is driven from the torque converter (31) in such a way that the air delivery pressure is determined by the difference between engine torque and the load torque. A valve (40) in the exhaust (41) is controlled both by the accelerator pedal (24) and the pressure sensitive diaphragm (44).
Patent FR-2287583-A1 (FR)
Title: Adjustable hydraulic valve control - for inlet and outlet valves of reciprocating IC engine
IPC: F01L9/11
Filed: 1975-10-09
Abstract: The hydraulic control arrangement consists of a hydraulic cylinder and piston which is driven by a camshaft. The piston pumps fluid to a control cylinder with piston which acts against the valve. When the top of this piston reaches a by-pass channel in the cylinder, the hydraulic fluid can flow back directly to the fluid reservoir and the piston stroke is ended. The first piston pumps more fluid than is required for the movement of the valve. The first piston has an annular groove which is connected to the pressure side of the pump. A sleeve with control edge is mounted over this groove, and can be moved to and fro over the piston relative to the annular groove and controls the position at which the fluid from the pressure side is returned to the fluid reservoir.

The first flip-flop MOSFET (1) is connected by its drain to the gate of a seventh MOSFET (7) and the gate of the corresponding control MOSFET (5) is coupled to the output of an eighth MOSFET (8). The gate of the second control MOSFET (6) is coupled to the output of a tenth MOSFET (10). The timing generator consists of an ohmic resistor (12) and a capacitor (13) regulated, via the switching transistor (7), by the flip-flop.

Title: Isolating lipase and labferment enzymes - from medium residue used in vibrio cholera cultivation
Inventor: DODIN ANDRE AIME
IPC: C12N9/52
Filed: 1976-02-20
Abstract: Enzymes, partic. lipases and labferment, are obtd. by isolating them from the culture medium residue from which vibrio cholera microorganisms have been isolated. The lipases are used partic. for the destruction of fat bodies (e.g. in measuring methods) and also in preserving bread. The process provides a new source of these enzymes from the residue of vaccine prepns. The enzymes may be isolated by filtration or centrifugation of the culture medium to obtain a soln. which is treated with ammonium sulphate to ppte. the enzymes which are then centrifuged. The enzymes are sepd. in a known manner, such as chromatography of the solns., or by dialysis, esp. to separate labferment.
Patent FR-2343518-A1 (FR)
Title: Paint roller with brush attached - uses brush to spread paint more evenly and eliminate air bubbles
IPC: B05C17/02
Filed: 1976-03-09
Abstract: A paint roller with a conventional cylindrical plastics foam applicator surface has a rod frame with one end passing through the cylinder acting as a spindle, and bent over with a shorter portion parallel to the spindle, with a brush attached to it. The handle is mounted on a further extension of the rod so as to slope at an angle of 45 deg. to the plane of the brush. This brush is slightly wider than the roller and is used to distribute the paint more evenly and also to eliminate air bubbles, especially in adverse conditions. In an alternative design, the handle is fastened by a block onto the spindle, and a screw on the block allows the handle to be locked at a required angle.

Title: Reciprocating workpiece chute for automatic lathe - advances to catch finished piece as it drops, and retracts to allow parings of subsequent piece to fall into bin
IPC: B23Q7/12
Filed: 1977-02-11
Abstract: The linearly reciprocating chute (6) is for use in recovering workpieces (4) produced by an automatic cycle lathe (1). The chute (6) adapts to conventional machinery where the finished piece (4) usually drops into a bin (5) collecting the parings. The chute slides into place to intercept the piece (4) as it drops, and then retracts until the subsequent piece is dropped. The chute may slide within a rectangular hollow section guide (7). The guide (7) falls away from the lathe (1) towards a recovery tray (26) which is approx. half as long as the chute. A pneumatic ram (11) mounted on the side of the guide (7) engages a chute-lug projecting through a longitudinal slot, and displaces the chute relative to the guide (7). The movement of the chute (6) may be co-ordinated with the lathe cycles by a rotating cam (21) and contact-breakers (20).

These give a signal which disconnects the drive when a certain value is exceeded.
Patent FR-2352678-A1 (FR)
IPC: B44C7/02
Filed: 1977-03-10
Abstract: A profile rail (10) is used for retaining the edges of wall-covering webs. It has a region (13) which flattens in a wedge-shaped manner towards a rail edge (11), as far as the bearing surface (12) of the rail, and which is adjoined by two walls (14 and 15) which are parallel to, and at a distance from, each other and define a clamping groove (16) which is open towards the narrow side of the profile rail (10). One wall (14) forms a part of the bearing surface (12) of the profile rail (10) and has a web (17) which runs parallel to, and at a distance from, the opening edge of the groove (16). The other wall (15) forms a part of the upper side of the profile rail (10) which runs parallel to the bearing surface (12) and is provided with a self-adhesive strip (18) which is covered by means of a protective strip (19) which can be torn off.

Title: Swivel bearing for large crane - has balls to resist tipping moment, supported by aligned semi-circular grooves in inner and outer rings
IPC: F16C19/54
Filed: 1977-04-14
Abstract: The swivel bearing has a fixed outer ring(1) and a rotating inner ring(2) which is supported by a row of rollers(6). The inner and outer rings(2, 1) have circumferential grooves(16, 17) of semicircular cross-section to support the row of balls(7). These grooves(16, 17) are so aligned w.r.t. each other, that the line joining the points of contact(18, 19) makes an angle alpha with the bearing axis. When a tipping moment is exerted on the bearing by the load being lifted by the crane, the angle alpha tends to increase so that the capacity of the bearing to resist this tipping load also increases.
