Title: Nuclear fuel element sub-assembly - with coolant flow limited jacket temp around elongated needle matrix
IPC: G21C3/32
Filed: 1971-04-20
Abstract: Elongated needle shaped, sheathed fuel elements are spaced parallel to each other as a bundle within a jacket, esp. hexagonal and of stainless steel, through which the coolant flows. To prevent distortion and deformation of the jacket, which would render difficult and perhaps dangerous any refuelling operations, the flow of coolant in the jacket is canalized by inner shells etc., in such a way that the temp of the jacket is held outside the range 450-500 degrees C. The rate of swelling of the jacket material when exposed to radiation is thus significantly less than the maximum rate of swelling.

Patent FR-2249274-A1 (FR)
Title: Gas pipe control valve controlled by leak detector - is prevented from closing until leak is detected
IPC: F16K31/00
Filed: 1973-10-26
Abstract: The valve (1) is mounted on a shaft (4) which may be rotated by the rack (6) acting on the pinion (5). The rack is actuated by the spring (7) but is normally held against the spring pressure by the armature (8) of the solenoid (10). When the solenoid is activated by an electrical signal from a malfunction or gas escape detector, the armature is retracted and the rack is then free to rotate the valve to the closed position. The jockey wheel (11) reduces friction and also operates the electrical interlock microswitch (12). Manual resetting of the valve is achieved by turning the squared end of the shaft (13) when the fault has been cleared. The main advantages are high speed response without the need for human monitoring.

Title: Mould for foodstuffs in paste form - has ribbed sides with edged flanges and has uprights and handles
IPC: A01J25/13
Filed: 1973-10-26
Abstract: The mould is made in stainless steel, and is ultra-light. It consists of a rectangular or square box (1) with four sides which have edged flanges. There are angle iron reinforcements (2) with the flanges facing outwards at each of the corners and there are vertical sections (3) which press against the ribs (5) of the side walls preventing distortion resulting from internal pressure. The ridge of the ribs faces outwards resulting in a space between the side wall and the reinforcing section, thus facilitating cleaning. A hand grip could be provided on the long or the short sides. The angle iron reinforcements on the sides have the flanges facing outwards at 45 deg. to the side being reinforced.

Method provides a flexible sealed lining without micropores, thus preventing escape of the foamable material.
Patent FR-2285765-A1 (FR)
Title: Telephone locking system for restricting calling ability - has key operated mechanism to limit dial or pushbutton selection
Inventor: RICHARD PIERRE
IPC: H04M1/667
Filed: 1974-09-17
Abstract: The key operated mechanism is for subscriber telephone sets and when operated limits the code selecting ability of the dial such that only local calls may be made. The design is equally applicable to button operated sets. The set is built to accept a lock operating a code limiting circuit in the body of the set, either multi-frequency or decimal code and is arranged such that the key must be rotated through 360 degrees between insertion and withdrawal, the actual operating mechanism within the lock moving through 40 degrees. Due to the 360 degrees rotation it is not possible to detect whether the dial is limited or not.
Patent FR-2286095-A1 (FR)
Title: Multiple lift control system - has lift cages making or breaking contacts in resistance circuit representing routes
IPC: B66B1/16
Filed: 1974-09-30
Abstract: The system ensures that only the nearest of the lift cages is called to serve a particular floor. As the cages travel they make or break an electrical contact in a resistance circuit representing in the control unit the routes taken by them. The contacts can not be on the sets of resistances representing the cages either travelling or stopped, without a programmed direction. The call circuits can be connected via contacts representing the call, using two sets of resistances connected to opposite sides of a third reference resistance in the main circuit, for stopped cages. For moving cages there is a resistance circuit per direction.
Patent FR-2255516-A1 (FR)
Title: Control for hydrostatic transmission motor - movement of control valve piston is linear with increasing output pressure
IPC: F03C1/00
Filed: 1974-11-27
Abstract: The directional command for the hydraulic motor (7) is given by a valve in which the piston is normally held centrally by two springs. An auxiliary pump feeds fluid to this valve via a feed pipe (21) and a three position direction switch (9). A second pipe (22) connects the valve via a pressure regulator valve (16) to the fluid reservoir. Depending on the pump output pressure (3) the regulator valve either discharges the control fluid to the reservoir (normal) or puts the full control pressure on the direction switch (high). In the latter case the pressure back-up neutralises the piston in the control valve and reverses the motor. The pressure regulator valve has a two-piece piston, interconnected by springs, to give a movement directly proportional to output pressure.
Patent FR-2293831-A1 (FR)
Title: Compensation circuit for Hall effect sensors - has RC network which integrates voltages generated by varying magnetic fields
Inventor: LAMARCHE JEAN-LUC
IPC: G01R33/07
Filed: 1974-12-06
Abstract: The circuit provides compensation for Hall effect sensors, where the wiring necessary for measurement of the normal Hall effect voltage forms a closed loop in which are induced parasitic voltages if the magnetic field is varying in time. The circuit consists of an integrating arrangement of a single or two resistors in series with the Hall sensor output leads and a capacitor across the output side of the resistors. A meter in parallel with the capacitor provides measurement of the Hall effect output, the second resistor provides offset voltage compensation. Correction for fields varying over the range 50-100Hz. Between -40 and +100 deg.C. requires C = 1 nanofarad and R = 100 kilohms.

Title: Travelling dolly for opening and reloading tyre moulds - with inter-locked clamp guides to facilitate automatic control
IPC: B29D30/06
Filed: 1975-02-28
Abstract: Tyre vulcanisation system has a series of tyre moulds in a row which are automatically opened, unloaded, reloaded and closed by a travelling carriage fitted with claws for releasing and lifting the upper mould halves from bayonet fitting clamps and moving the mould tops aside to allow other claws to unload and reload the base moulds. The mechanical linkages are such that the mould covers are removed by solitary action of the first set of claws but that the refitting of the mould tops is aligned and operated in conjunction with the action of the second set of jaws after they have reloaded the mould with a prefabricated, uncured carcass. Both jaw systems progress together along the series of mould tools. Design minimises the number of independent controls involved in positioning the grabs laterally and vertically, simplifying automation of the equipment.
