Patent FR-2524576-A1 (FR)
Inventor: GILMER ANDRE
IPC: F04D13/10
Filed: 1982-03-31
Abstract: A motor-pump unit for submerging down a well, e.g. an oil well, comprises a motor portion driving a pump portion. The motor portion is filled with fluid to prevent ingress of the surrounding medium which the pump portion pumps. The fluid is maintained at a higher pressure than the surrounding medium by including a flexible tank filled with fluid and in communication with the fluid in the motor portion. The flexible tank is compressed both by the surrounding medium and by resilient compression means so that the pressure inside the motor is higher than the surrounding pressure, thereby ensuring any leakage is outwardly from the motor. Down the well the temperature rises causing the fluid to expand, so the flexible tank is left substantially empty when the unit is prepared at the surface prior to lowering. If a large rise in temperature is to be expected, a resilient compression means which provides adequate excess pressure near the top of the well as the unit is lowered, will provide too much excess pressure at operating depths, and similarly compression means which provide adequate excess pressure at operating depths do not supply enough near the surface. This problem is solved by providing compression means which includes a first spring (79) and a second spring (80) so disposed that the flexible tank (66) is subjected to the sum of their resilient thrusts, with the second spring applying its thrust via release means (83 to 88) which cause said second spring to be released and to relax once its displacement reaches a predetermined value.

Title: Split rack assembly for play-free pinion drive - uses spring-loaded sliding rack housed in main rack to maintain teeth in contact with pinion
Inventor: AGOSTINO GUY D
IPC: F16H55/28
Filed: 1982-04-21
Abstract: A hydraulic jack comprises a body (1) forming a cylinder (2) in which a piston (3) slides. The piston forms part of a shaft (4) which is extended by a toothed (5) rack (4a). The rack and shaft have a blind hole (6) in which a second rack (7) is able to slide. The teeth (8) on this rack are located in the same plane between the two toothed parts of the rack housing it. A helicoidal spring (10) is located in the blind hole to press its ends against the base of the hole and against the end of the second rack. The teeth on the two racks engage the teeth (11) of a pinion (12) carrying a cam (14) and which rotates on a shaft (13). Operation of the jack causes pinion and cam to rotate and the spring action acts on second rack to keep the teeth in contact with the teeth on the pinion to take up any play.

Title: Profiled tray pack for storage of fruit, etc. - moulded from dry cellulosic pulp in cold pressing operation
Inventor: SORBIER JACQUES
IPC: D21J3/00
Filed: 1982-05-04
Abstract: A moulded tray-pack of cellulosic fibre for the storage and transport of fruit, vegetables, etc. is manufactured from a pulp having a moisture content of less than 50%. The pulp is built up to the required thickness in several layers, in between which a bonding agent is sprayed, then cold-pressed between moulding dies under a low pressure of approx. 1 bar to form a profiled tray. The raw material may be derived from sheets of chemical or mechanical cellulose pulp, recycled card or paper, or other cellulose-based material in suitable form. It is conditioned to a moisture content of 30-50%, then shredded and finely divided in a single operation in a mill having rotating wire-clothed cylinders. This is a simple, inexpensive process producing a strong tray which helps to preserve the fruit, etc. in good condition.

Abstract: The invention relates to a clock with two phases, with no overlap, which can be produced as an MOS integrated circuit of period adjustable to the operation of the circuit to be controlled. The clock with two phases phi 1 and phi 2, with no overlap, consists of two coupled oscillators each including a gate P1 or P2, of NOR type with two inputs, the output of which is connected to two delay lines LR1 and LR2 or LR3 and LR4 connected in cascade. The delayed signal provided by the second delay line LR2 or LR4 is reinjected onto the first input B or D of the NOR gate. The second input C or A of the NOR gate constitutes the control or coupling input to the other oscillator. It is connected to the output of the first delay line LR3 or LR1 of the other oscillator. The assembly can be integrated on the same wafer as the circuit to be controlled. The delay lines consist of an even number of invertors.

Title: Automatic controllable-pitch propeller independent of any manual command in both forward motion and backward motion
IPC: B63H3/00
Filed: 1983-11-21
Abstract: Automatic marine or aerial propeller device which is entirely autonomous in both forward motion and backward motion. According to the figure, the device consists of a boss 5, in which, when the engine torque is positive, planet wheels 4 and 10 mounted on a shaft 13 move. These planet wheels 4 and 10 control satellites 9 and 9 bis, on which the blade feet 17, 18 of the propeller are fixed. A projection 8 bis, the essential subject of the invention, undergoes an angular displacement between the positive clutches 7 and 8 which allows the blades to have an optimum angle of attack when the projection 8 bis comes into abutment, according to the direction of rotation of the driving shaft. A shaft or torsion spring 3 restores the energy stored at the precise moment when the engine torque is zero. At this moment, the blades of the propeller return exactly to the feather position, which closes the operating cycle. The device according to the invention is intended in particular to serve motor boats such as sailing boats, trawlers, fishing boats, multi-engined boats, as well as all aircraft with propellers and light motorised units.

Title: Method relating to the conversion of lost roof spaces into useful roof spaces in dwelling houses
IPC: E04G23/02
Filed: 1983-12-22
Abstract: This method amounts to placing prefabricated trusses with a so-called tie beam, which are especially truncated and have rafter-raising blocks (drawing number 5), making it possible to place them onto raising blocks which are integral with the load-bearing walls, by sliding after only part of the roofing pane has been laid. (Existing roofing - roof battens - crossbracing). After the new trusses have been placed, they are fixed by screwing against the old trusses, in order to take over their use and to allow the internal members of the old trusses which have become redundant to be cut. After crossbracing and buckling prevention, the placing of a floor in timber or agglomerate allows the space which has thus been cleared to be used. As necessary and depending on the accessibility of the site, the sliding of the trusses on a tie beam may be carried out mechanically or manually by means of rollers positioned on the old trusses.
