Patent FR-2083634-A1 (FR)
Title: Moulding foamed plastics articles - with decorative pattern
IPC: B68G7/00
Filed: 1971-03-08
Abstract: A plastic sheet elastic in two dimensions formed from a woven support covered by a thermoplastic layer and designed to fit the inner wall of the mould exactly, is applied to this wall by reduced pressure prior to the injection of the material to be foamed and is provided with a decorative design on its visible surfaces. The thermoplastic material impregnates the woven fabric so that the constituent yarns are adhered to the thermoplastic layer on one side and project on the other side. Alternatively the plastic sheet may have a decorative design on the visible face and on the interior invisible face may be treated mechanically, physically, or chemically to cause it to bond directly to the polyurethane foam. The mouldin g proper is then carried out by injection the material to be foamed, closing the mould while maintaining it under reduced pressure so that the thermoplastic sheet accurately fits the inner walls of the mould, and until the foamed material has reached its dimensionally stable state and is no longer deformed. The product is foamed plastic moulding bonded to a sheet sufficiently elastic to permit it to undergo the shape changes to which it will be subjected during use.

Patent FR-2260890-A1 (FR)
Title: Electrical machine cooling system - uses fine water and air mist to improve cooling heat exchange
IPC: H02K9/20
Filed: 1974-02-12
Abstract: The motor cooling agent is a fine mist of water and air. The air is circulated around the windings by the motor ventilation system and water droplets are introduced by nozzles which project in the airstream. The heated mixture then exhausts to the atmosphere. In the case of sealed motors, the air can be replaced by a gas such as hydrogen and the water can condense around an internal cooling jacket and be reintroduced as droplets by nozzles as before. This cooling system takes advantage of the improved high-humidity performance of machines and the thermal characteristics of vaporising water.

Title: Composite modular insulating and structural wall panels - incorporating expanded polystyrene insulation and butyl and polysulphide seals
IPC: E04C2/04
Filed: 1975-09-17
Abstract: Wall panels incorporate a layer of expanded polystyrene between layers of reinforced concrete. The vertical edges of the panels have large trapezoidal channels where tie wire loops from adjacent panels can overlap and be interlocked by rods passing through the loops. The vertical edges also define an interstitial small trapezoidal channel for accepting a supported seal and small hemispherical grooves for venting the interface. Used as modular wall elements for load bearing structures up to 10 floors high. Each panel may be the height of 1 storey, up to 4.5 m wide and weight up to 5 tonnes. The design provides continuity of the thermal insulation layer and freedom from potential thermal bridges, so that the 'K' value for thermal insulation of the structure is 1, typically about 0.5 W/m2 degrees C.

On the inside, i.e. on the side away from the cutting edge and on the inner side of the chamfer there is connection to a downwards inclined flank, on the lower and inner side and lower and inner edges of which there is connection in the centre to a correspondingly deeper, parallel plane (28) to the chamfer, so that in no way is a rising swarf breaking flank present.
Patent FR-2291474-A1 (FR)
Title: Diesel engine injection timing equipment - has computer producing signal representing advance period before top dead centre
IPC: G01M15/12
Filed: 1975-10-08
Abstract: A first unit generates a signal on the start of injection into a reference cylinder of the engine, while a second one produces first and second impulses in accordance with movement of the crankshaft through a predetermined number of degrees, the second impulse being at TDC. This causes a third unit to emit a signal representing the time interval between the impulses. The first and second units cause a fourth one to emit a signal representing the time interval between fuel injection and the second impulse. A computer multiplies the ratio between the signals from the third and fourth units by a signal representing the number of degrees between the impulses. This produces a signal showing the time interval between the start of injection and reaching TDC.

Abstract: A support table for a recumbent patient has a table plate provided at least along the side edges, and preferably also at the head and foot edges, with gate members which are pivotally mounted so that they can be fixed in up positions. In the up positions the gate members not only keep a patient from rolling off the table but they cooperate with a mattress on the table to form a trough in which water may be retained for bathing the patient. The mattress has an outlet for discharging the water after bathing. In the down positions of the gate members the mattress edges are also folded downwardly.
Patent FR-2337636-A1 (FR)
Title: Road vehicle speed limiter - has selector switch and speedometer contacts and detects engine oil pressure to regulate carburettor
IPC: B60K31/12
Filed: 1976-01-12
Abstract: The road vehicle speed limiter has a multi position switch (8). When the selected speed has been reached a mechanical governor (2) in the speedometer acts on contacts (7) fed by the switch (8). This then actuates an electro valve (1) in the engine oil pressure circuit. The valve feeds oil to a bellows (4) which can be deformed and acts on the accelerator cable, connected to the butterfly valve control (6). Oil flow from the bellows is via a strangler valve (5). The overall effect is that vehicle speed is maintained at the desired level.
