Patent FR-2329911-A1 (FR)
Title: Pressure vessel for use at extremely high pressures - with strength increased by magnetic field generated by electric current
IPC: B01J3/00
Filed: 1975-11-03
Abstract: The cylindrical pressure vessel has a conical cover and a spherical base. The strength of the vessel can be increased by a factor of >100 by electric currents of up to 100 000 amp. flowing along the length of the vessel. The vessel is a large number of parallel conductors each carrying an electric current. The currents generate magnetic fields which repel each other so that a compressive tangential force arises which resists the hoop stress due to internal pressure. The compressive force has a radial component (Q) which in turn has horizontal and vertical components (qr) (qn). The vertical components generated in the cover and in the base resist the longitudinal stresses.
Patent FR-2295550-A1 (FR)
Title: Pressure medium operated switch - has movable element which operates three sets of contacts one after another
Inventor: BOTTOMS HARRY SIMISTER
IPC: H01H35/34
Filed: 1975-12-16
Abstract: The switch comprises a body with a channel (14) for the pressure medium and the movable element is operated by the pressure medium and in turn operates a rocking bridge element which presses on the free ends of contact springs carrying the movable contacts; each movable contact requires a different pressure for its operation, with the first contact requiring the weakest force, and the third contact the strongest; when the pressure in the channel rises, the movable element and the bridge element are gradually moved, so that the bridge element closes contacts one-by-one. The bridge element rocks, so that the first contact is closed without second or third being closed, and the second is closed without closing the third.

Title: Test function generator for transmission channel or servo-mechanisms - produces complex periodic function by summing elements extracted from memory
Inventor: SILVENT ANDRE
IPC: G06F1/035
Filed: 1976-04-15
Abstract: The generator produces a complex period function from its components. Each of these components being defined by its amplitude, frequency, phase at the origin and its form. The generator processes the signals representing the arguments of an elementary period function for the diverse components. It has a memory in which is arranged a table defining the form of each component. The generator periodically consults the memory's table and produces an output signal. This signal represents the sum of the values of the periodic elementary function. This sum corresponds to the diverse components (balanced) compared with the values of the amplitudes corresponding to the same components. The generator periodically repeats these operations.

Thus a 30 [deg] set square has a slot made at an angle of 45 [deg] to one of the sides forming the right angle. Conversely, the 45 [deg] set square has a slot at an angle of 60 [deg] to one of the sides forming the right angle. All the edges are stepped so as to ensure a clean line as the drawing instrument is moved along it.

Title: Travelling gauge rod for railway track - has sensor following rail and linked to pen indicating deviations on reel of graph paper
IPC: E01B35/04
Filed: 1976-05-11
Abstract: The travelling gauge-rod is for use on permanent way railway track and automatically registers deviations in the track gauge width. A registered deviation coincides with a particular position of the vehicle, and if the deviation necessitates remedial work to the track the relevant sleeper is scribed. A graphic display gives instant indication of the deviation at that point along the track and the instrument may include a reel of graph paper with a gauge-width indicator. The latter may mark a line on the graph paper with gearing equating reel rotation to the progress of the vehicle.

Title: Stacker for packing machines - uses rotating crank arms to lift objects from conveyors and stack them in trays on the machine feed chain
IPC: B65B35/50
Filed: 1976-05-31
Abstract: The packing machine, such as a carton packer, places two or more objects directly onto the feed chain, avoiding all preliminary stacking. The machine consists of conveyor belts, equal in number to the number of objects to be placed on one stack, which feed the objects onto tables (5). The objects are then lifted from the tables by arms (18) attached to a crank (22) which is rotated about an axle (23). On the downstroke the objects are deposited on trays (17) attached to the feed chain, a wheel (24) on the bottom of the arm acting with a rail to rotate the arms outwards thus releasing the trays. With each cycle of the arms the trays move one place down the feed chain.

Abstract: A generator produces single-phase or multi-phase AC. It has a permanent magnet rotor that has "p" pole-pairs and is divided axially into at least two parts that work in unison with the same stator poles. The generator may be used as a bicycle dynamo. To overcome the difficulty in providing regulated excitation, so as to avoid excess voltages when the totor speed is sharply increased, one of the rotor parts is connected in locked-rotation relationship with the rotor shaft. The other part of the rotor is arranged on the rotor shaft such that the part can be rotatably displaced by a maximum of two pole divisions.

The cords have better long term flexural endurance than cords where adjacent concentric layers are overwound in opposing directions. Several concentric layers are readily wound on simultaneously if they are applied with the same sense of rotation.

Title: Double lift open shed Jacquard machine with single lifting wires - allows proper operation with minimum repair downtime
IPC: D03C3/24
Filed: 1976-09-06
Abstract: A Jacquard loom of the double lift-open shed type using single lifting wires is equipped with at least one stationary guide edge at the stationary arresting blade fixing the lower shed position. The guide edge co-operates with a projection at the neighbouring lifting wire moving into the lower shed position. This deflects the lifting wire and when it assumes the lower shed position it is coupled with the associated arresting blade. Possible errors which may arise regarding the coupling operation at the lifting wire entrainment hooks and the lifting blade entrainment hooks are during depressing or shifting of the depressing needles are immediately compensated by positive coupling or engagement. The operation of the Jacquard loom is free of disturbances and loom downtime.

Patent FR-2377912-A1 (FR)
IPC: B65G69/28
Filed: 1978-01-19
Abstract: When the stop device is in its operating position, the flap (3) is rotated, by the pressing of the nose (4), against the force component of the spiral spring out of the elevated plane level until the neck (9) of the flap (3) is supported on the surface (8) of the approach profile (2). In this process, the force component of the spiral spring (5) which is mounted on one side in a channel (10) of the approach profile (2) and on the other side in the channel (11) of the flap (3) ensures that the flap (3) remains in its operating position. The flap (3) and the nose (4) together form a rocker which is held in the "operating" or "out of operation" positions respectively by specific guiding of the force component of the spiral spring (5). This stop device structure, which is essentially composed of extruded profile sections, provides both a simple stop device which saves costs, as well as operating in a simple manner. The additional expenditure needed to ensure greater safety is therefore kept low.
