Patent FR-2246918-A1 (FR)
Title: Electrical indicator with additional floating battery - has facilities for maintaining indicated values in voltage breakdown
IPC: G01R13/00
Filed: 1974-10-08
Abstract: Electrical indicator elements have connected in parallel to them electro-mechanical auxiliary indicator elements which are normally inoperative. In case of voltage breakdown the floating battery is loaded only for the purpose of adjusting the indicated values on the auxiliary indicator elements. The connection to the auxiliary indicator elements is made via a agate which cuts through connectors in response to a signal triggered by a voltage breakdown and supplied by the floating battery. The supply of voltage for the indicator elements is maintained by the battery during transfer of the indicated values to the auxiliary elements. The apparatus thus operates continuously in spite of the breakdown.
Patent FR-2263407-A1 (FR)
Title: Device mounting plastic sheeting on structures - has springs holding plastic in troughs mounted on structure
IPC: F16B2/24
Filed: 1974-12-20
Abstract: Metal troughs (5) with a flat base, included converging sides (7) and outwards rolled top edges (8) are bolted to the greenhouse frame. The flexible, relatively soft sheeting (c) is laid on the troughs, pushed into them, and held there by 'zig-zag' springs (4). For harder materials a linear similar in section to, but smaller than, the trough is positioned between the sheeting and the spring. This liner is easily deformed due to it having a flexible base, thus allowing the liner to be press fitted into the trough, the hard sides of the liner pressing the sheeting against the sides of the trough.

Title: Weight for mechanical testing machine - has horseshoe magnet in base and top hook for suspension in end to end chain
IPC: G01G21/26
Filed: 1975-02-13
Abstract: Each weight (1) is made from a non-magnetic material, and is cylindrical with both ends flat and parallel. In one end (1a) is a hook (2), in the other end (1b) is a magnet (3). This magnet is a horseshoe shape, with north and south poles (3a, 3b) buried in the weight, its ends flush with the end face. One weight is fixed to another by respective magnets contacting each other. Additional weights are added by using the hooks. Having one end flat without a hook permits weights to be placed singly on a flat surface in a stable position, and the successive weights are alternately inverted.

Title: High quality red wine mfr. - in which marc is pumped from fermenting vessel while agitated by pumped juice
IPC: C12G1/032
Filed: 1975-06-12
Abstract: Fermentation of the grapes is carried out in a vertical, pref. cylindrical, vessel with its base sloped to fall to a large outlet for marc. As in traditional winemaking, the naturally drained wine ('Vin de Goutte') is first drawn off separately. The remaining marc is then extracted by pumping via the base outlet, flow to the outlet being assisted as necessary by juice pumped through an overhead spray and through small bore inlets near the base to force circulate and break up the marc. The pumps used both for marc extraction and juice injection are pref. rubber diaphragm pumps of the reversible type. Design eliminates labour-intensive, manual extraction of march without resorting to high cost installations using self-emptying fermenting vessels.

Title: Slide valve for hydraulic or pneumatic system - has spool with end chambers which receive free ends of respective rods whose pistons are subject to signal pressure
Inventor: MATROT PIERRE
IPC: F15C4/00
Filed: 1976-11-02
Abstract: The slide valve (1), forming part of a pneumatic or hydraulic system has an inner slide (4) with a separate piston (8, 8a) at each end which actuates a respective valve (13, 13a). A constant pressure is applied to the inlet (23) and is transmitted to the chambers (10, 10a). When a signal pressure, equal to the pressure in the chambers is applied to the inlet (11a) the inner slide (4) and pistons move to the right and the valve (13a) is opened causing the pressure in the chamber (10a) to fall. If a pressure is next applied to the other inlet (11) the slide (4) is pushed to the left because of the low pressure in the chamber (10a).

Title: Road vehicle electrically driven double ball screw jack - synchronises screws by comparing output from screw driven generators
IPC: B66F7/02
Filed: 1977-03-03
Abstract: A jack for raising a vehicle to provide access for undersealing is actuated by two electrically driven ball screws. The jack has two parallel cantilevers (4) which run on rollers on vertical guides (1). The guides (1) are held vertical by bracing members (2, 3). Ball nuts attached to the cantilevers (4) are engaged by vertical screws driven by an electric motor mounted on the upper cross beam (7). The two screws are synchronised by a device which compares the voltage from generators driven by each screw. A brake is then applied to reduce the speed of the faster running screw to maintain the cantilevers (4) at the same level.
Patent FR-2385471-A1 (FR)
Title: Continuous casting machine - has assemblies of pinch rolls in which adjacent rolls are individually driven
IPC: B22D11/14
Filed: 1977-03-31
Abstract: A cage is provided for a continuous casting machine, producing several slabs, housing pinch rolls. The cage has a housing supporting assemblies of several pinch rolls. Each assembly comprises a hollow pinch roll and a roll having a support axle extending rotatably through and coaxially with the hollow pinch roll. The rolls in each assembly are assembled in such a way that they are individually driven independently of each other. The space between adjacent slabs can be considerably reduced in comparison to prior art machines so that the machine can be reduced in size and can be cheaper. Since the space is reduced so can the casting vessel, and tuyere blockage can also be eliminated. The use of a small vessel enables the replacement of worn refractories to be cheaper. The rolls can be of a construction less complex than prior art devices and the cage can be of a very robust and simple construction.

Title: Two=stroke IC engine with stepped piston - has transfer port between crankcase and cylinder in piston instead of in cylinder
IPC: F02B25/14
Filed: 1977-04-29
Abstract: The engine has a cylinder with inlet and exhaust ports and a piston reciprocating in it. The piston has a wider lower section and a narrow upper section. The narrow section slides in a narrow extension at the top of the cylinder. The working surface is formed by the conical transition between the wider and narrower sections of the piston and combustion takes place below the upper projection of the cylinder. The transfer port between the crankcase and the cylinder is formed in the upper narrow section of the piston. The port is closed when the narrow section enters the upper portion of the cylinder and opens again on the next downstroke. The design reduces limitations on possible port sizes.
