Title: Vehicle propulsion device with drive motor - has centrifugal hydraulic pump forcing fluid against reaction casing
IPC: F03H99/00
Filed: 1974-08-09
Abstract: A propulsion device for a vehicle has an impeller mounted on a shaft running in bearings in a casing. The casing is filled with oil which is driven, by centrifugal force generated by the rotating impeller, through the passageways formed between the impeller and a shroud. The axial component of the thrust exerted on the shroud due to centrifugal force is used to propel the vehicle in which the device is installed. After leaving the impeller the oil impinges on the blades of a turbine which drives the impeller through a torque converter. The device thus exerts thrust without using a jet of air or water and with negligible energy consumption.
Patent FR-2284726-A1 (FR)
Title: Fixing of tensioned fabric veneers on walls - by applying fabric with edge overlapping batten to adhesive layer on batten
IPC: B44C7/02
Filed: 1974-09-10
Abstract: The method of fixing linings, particularly woven material, under tension on walls uses adhesive fixing battens with grooves for reception of lining sheed edges. The method removes the need for closure battens and lining edge binding. Installation entails the fixation of the batten to the wall followed by the pressure or heat application of the lining hem to the batten. This initial lining fixing is made with the sheet edge projecting beyond the groove, the excess them beng trimmed off with a razor blade or the like if one form of groove (Fig. 5) is used, or simply folded into a wider alternative type groove. (Fig. 6). Alternatively the battens can be split in two longitudinally and used in pairs.

Patent FR-2299746-A1 (FR)
Inventor: PAL IMRE
IPC: H02G1/12
Filed: 1976-01-27
Abstract: In order to prevent damage to a coaxial cable during removal of a piece of its screen, the cable end (c, d, f) is initially passed through the hole of a cutting plate (1) and is subsequently pushed into or onto a tubular cutting die (2). The piece (L1) of the screening mesh (c) to be cut off at the same time comes to rest on the outer envelope surface of the cutting die (2), while the conductive and insulating components, which are located under the screening mesh (c) to be cut off, are inserted into the space inside the cutting die which is constructed as a blind hole. During the operation, the cutting die (2) is pushed together with the cable end thus placed on through the hole in the cutting plate (1), as a result of which the screening mesh is cut off. In this case, the force components which endanger the intactness of the said components of the cable are absorbed by the cutting die (2).

Title: Monobloc electric resistance heating element - has heat source in direct contact with diffuser to give improved thermal efficiency
Inventor: LAJOUX PIERRE
IPC: H05B3/50
Filed: 1977-02-01
Abstract: The electrical resistance heating element is designed to have a high thermal efficiency. The resistance element (1) is surrounded by magnesium (2).

Abstract: The grinding or polishing tool for flat surfaces is driven with a fast to and fro movement of small amplitude. The grinding/polishing wheel mounting is moved across the surface at a speed which is reversed when the tool reaches the edge of the workpiece. The tool mounting is moved in cycles across the surface to be finished following two speed vectors which are at different orientations. Both vectors are at an angle to the to and fro movement of the tool. A first motor moves the tool or the work carrier in a first direction and a second motor carries out the same movement in a second direction. An arrangement alternatively reverses the drive direction of the two motors when the edge (2) of the surface (1) is reached.
