Patent FR-2273223-A1 (FR)
Title: Thermal insulation element - has insulating pads on backing material folded to form boxes or channels
IPC: F24H9/02
Filed: 1974-05-29
Abstract: The thermal insulation element may be easily assembled to and dismantled from various shapes. Layers of fibrous insulating material such as cermic or alumina are bonded with suitable heat resisting cement to a backing material. Parallel channels are left between the insulated areas equal to the insulation thickness so that when the support is bent at right angles, along one edge of an insulated area, a continuous insulating layer is formed on the inside. The support extends beyond the length of insulation, so that an assembly flange is formed. It is possible to form multiple flanges for mounting hinges may be used instead of bending the support in the case of rigid support material.

Title: Microwave frequency transmit-receive assemblies - has resonant cavities coupled to circular wave guides via wave guide slots
Inventor: ROUSSET RAPHAEL
IPC: H01P1/161
Filed: 1974-07-10
Abstract: A rectangularly polarised wave generated by a semiconductor diode oscillator (11) passes through a quarter wave impedance transformer (12) to a circular waveguide (13). This allows the wave to pass to a truncated conical shaped revolving antenna (14). A rectangular resonant cavity (15) is coupled to the waveguide by a longitudinal rectangular window (16) and is attached to the quarter wave transformer by two screw threads (23, 26). The cavity contains a microwave detector diode mounted on a conducting pillar (30). Tuning and impedance matching is enabled by a piston (31). Two assemblies are carefully aligned on a plate and one is used for transmission and the other for reception.

Title: Beryllium based superconductor - has theoretical critical temp of twenty five degrees Kelvin
Inventor: KLEIN JEAN
IPC: H01L39/12
Filed: 1974-09-17
Abstract: Superconducting material made up in a thin film of a fine granulat structure, the grain size being 10 angstroms. The material is a berylium based alloy of the form, Be1-xRex. (0.5% x8.0%). Other elements may form the alloy, i.e. molybdenum, tungsten technecium, providing a high debye temp, characteristic. The critical temp. is theoretically 25 degrees K allowing the use of liquid hydrogen. The alloy is evaporated in an oxygen atmosphere onto its support structure, the evaporation being achieved by cathodic bombardment at radio frequency from a silicon oxide or aluminium base material. This process may be equally well accomplished using a filament heater or laser bombardment. The support structure is maintained at liquid nitrogen temp.

Title: Scaffolding system for hold of ship - has elevator pairs on columns supporting platforms with travelling working positions
IPC: B63C5/02
Filed: 1974-11-08
Abstract: The system has columns at four corners (15), and two pairs of elevators working up and down the pairs of front and rear columns. These pairs of elevators support platforms (35, 36) on which there are mounted working positions (37) travelling along the front and rear walls of the site. Lateral girders join the tops of the front and rear columns and carry guide rails, and second elevators travel up the columns, having rails brought into line with those on the girders, so that rail trucks can be transferred between them, and the pairs of trucks support second platforms, along which other working positions travel along the left-and right-hand walls of the site. Each second platform travels along the lateral girders, allowing work to be carried out on the hold roof also.

Title: Hand lever safety cover - has cut out to receive handle and is weakened along junction with mounting flange
IPC: F16K35/00
Filed: 1975-02-21
Abstract: This safety cover is intended for use on hand levers which operate ventilators or fume extractors in emergency. The cover (5) is in the form of a box having a projecting lower flange (5e) drilled for mounting on a wall. The two vertical sides of the box are slightly shorter than the box height so that on one side, the handle (3a) of the lever (3) actuating the ventilator control can protrude and is therefore located by the cover.

Patent FR-2346051-A1 (FR)
Title: Centrifuging and redissolving crystalline sugar in one operation - ejected crystals sluiced at high pressure in turbulence chamber
IPC: C13B30/10
Filed: 1975-11-20
Abstract: A mass of fluid and sugar feed continuously from the crystallisers into a continuously operating centrifuge, is separated and redissolved by bringing the ejected sugar into contact with solvent fluid as it leaves the centrifuge. Immediately on passing the top edge of the centrifuge basket the crystalline sugar is subjected to the impact of a solvent fluid from nipples, the jets being directed, as the sugar follows a path, at an angle to it. The high degree of turbulence in the outer chamber formed by the inclined baffle, sets up a cloud of vapour which impinges repeatedly against the chamber sides, and follows the contour to a point where the air, crystals, vapour and already dissolved matter bank up before being forced through a narrow gap and over the rim of a dam and drained off for processing. The concn. of the sugar soln. obtained is maintained at the optimal value by measuring the temp. of the soln. as it drains off. Any deviation from a nominal value registered, generates a control signal for altering the input from the crystallisers and/or the solvent fluid tank, the temps. of the charge and the solvent being kept constant at values differing slightly from each other. The sugar thrown outwards from the rotating basket is redissolved completely within the centrifuge, and a product with a high degree of purity results.
Patent FR-2342409-A1 (FR)
Title: Double acting reciprocating hydraulic motor - has elastic end stop for reversing rod to avoid premature reversal of valve
IPC: F01L23/00
Filed: 1976-02-27
Abstract: The motor has a piston (4) working in a cylinder (5). A reversing rod (12) is displaced by the piston every time it reaches one end of its movement, and carries a valve slide (9). The valve slide can also slide laterally within a recess in the top (11) of the reversing rod (12). This movement is effected by an auxiliary piston (13) perpendicular to the axis of the motor. The auxiliary piston is moved by fluid admitted to its end by ports (18, 19) uncovered by the valve slide (9). There is an elastic end stop (36) against which the reversing rod (12) presses at one end of its movement. This allows sufficient free movement to prevent the reversing rod moving the auxiliary piston prematurely.

Title: Sealing cap for container - has supple sealing ring which engages under lip on container and covers edge of stopper
Inventor: COURNUT RENE
IPC: B65D41/58
Filed: 1976-03-29
Abstract: The sealing cap is designed for cases or flasks containing medicines or dangerous products so that it cannot be removed by accident. It consists of a supple ring (4) which fits over the stopper (3) of the container (1). The ring has a cylindrical wall (5) terminated at the top by a supple lip (7)which fits over the stopper and terminated at the bottom by a thick lip (6) which fits firmly under the collar of the container. To an unaware observer the cap appears to only one piece but it cannot be pulled off and attempting to unscrew it merely rotates the sealing ring. The cap is removed by prising the top lip of the sealing ring over the rim of the stopper.

Title: Temp. regulation system for liq. bath - uses heat exchanger assembly maintained at minus 78 degrees centigrade
IPC: G05D23/13
Filed: 1976-05-13
Abstract: The first enclosure contains methanol which is to be maintained at -30 deg.C. The enclosure has an agitator on a shaft driven by a motor. On the shaft there is a centrifuge pump. When the pump operates the methanol is pumped through the opening and passes into the pipe towards a regulating valve. From the valve the methanol is led by a pipe to an 'all or nothing' valve. A pipe passes into the heat exchanger maintained at a temp. of -78 deg.C. The methanol is also circulated by pipes and a valve which bypass the heat exchanger. When the methanol temp. in enclosure rises above -30 deg.C valve is opened so that the methanol can pass into the heat exchanger. The methanol circulated through the heat exchanger mixes with the methanol passing through the bypass pipe (16) into the input pipe.
