Title: Plasticiser and injector - in combined unit for high pressure injection
IPC: B29C45/23
Filed: 1972-06-23
Abstract: A preplasticiser and injector, for thermoplastics, thermosetting plastics and elastomers comprises an injection cylinder, in which there is slidably mounted an injection piston containing a central longitudinal duct which receives the material direct from the preplasticiser. The piston is advanced to eject material from the nozzle by a ram mechanism, the outlet from the piston longitudinal duct into the injection cylinder being enclosed by a valve during this advance stroke. For the return stroke, the valve is opened and the pressure produced by continuing feed of material causes the piston to retract. Pref., the barrel of the preplasticiser is connected to the rear end of the piston and contains the plasticising screw, so that the whole of the preplasticiser unit advances and retracts with the piston. The material is injected in the same sequence as that in which it is plasticised, and the injection pressure does not react back against the slender plasticising screw.
Patent FR-2202037-A1 (FR)
Title: Pulsating freezing bell - for purificn. of sea-water
IPC: C02F1/22
Filed: 1972-10-10
Abstract: Annular heat exchangers are housed under an insulated shell. The freezing bell, with a thin, resilient wall of undulating cross-section, is deformed periodically by flexible sagging, so that ice cannot form during the heat exchange. This fluctuating internal tension is caused by the freezing fluid running down against the internal undulations of the bell, and the rhythmic variations in tension are produced by suction and are followed by the resilient relaxation of the bell. The press. is rapidly restored by the internal evapn. of the freezing fluid. The ice crystallises in the liq. in the freezing chamber, rises to the surface to be collected by a rotary device, and is then transferred to the heat exchanger where it melts. Purificn. by freezing uses less energy than by distn. and with the new system no complex mechanism is needed for breaking the ice, since it does not adhere to the heat exchange surface. A fixed or portable freezing bell operated by muscular or other form of energy, is suitable for sea-side camps and for use in ships. Larger units can supply villages with fresh water.

The sides incorporate a U-profile slot with a steel wire stringer.
Patent FR-2222592-A1 (FR)
Title: Sensitive safety valve for hydraulic circuit
IPC: F16K17/04
Filed: 1973-03-22
Abstract: The pressurized fluid circuit is connected to the valve's chamber through a passage in its base which is closed by means of a small ball pressed against its seat by a spring assembly such as a stack of bellville washers. The other end of this stack forces another ball against the outlet passage in a part which, for adjustment purposes, is screwed to the top of chamber. The spring moves axially without touching the walls and this lack of friction enables a smaller difference between opening and shutting pressures. Flow may reach the outlet passage through openings around the outlet seat, to allow flow with the outlet ball on its seat.

Title: Wave shed loom magnetic shuttle drive - with friction force between shuttle and shedding mechanism eliminated
IPC: H01F7/02
Filed: 1973-03-27
Abstract: At reat, the shuttle magnet assembly of magnets polarised perpendicularly to the direction of movement, alternately polarised, lie over, and are attracted to, the similarly arranged driver part, with a small air gap between. The driver perpendicularly orientated magnets are smaller and between them have magnets polarised in the motion direction, whose poles are, on the air gap side, arranged with like poles of the perpendicularly orientated magnets. When the driver moves, its poles are displaced to come towards like poles of the shuttle magnets, which repel, giving not only driving force but also separating force levitating the shuttle to eliminate friction.

Patent FR-2241136-A1 (FR)
Title: Colour TV CRT luminescent screen prodn - uses perforated mask for projection illumination of deposited phosphors
IPC: H01J9/227
Filed: 1973-08-17
Abstract: The luminescent screen is formed by using a light from a source, projected through a perforated mask on the screen phosphors. A tubular light source is used for projection through an elongated slit in a sheet metal plate. The light source and the slit intersect and are so formed and of such relative arrangement that the light coincides with the movement of a deflection centre which may form a point from which an electron beam starts. This results in coincidence of the electron beam focal point from an electron gun with an associated phosphor point on the screen. The elongated light source may be arcuated and the intersecting slit linear, or vice versa. Alternately both the light source and the slit may be arcuated.

Title: Attachment method for two documents - uses window on second page located over adhesive strip on first, secured by tape
IPC: B42F5/00
Filed: 1973-09-20

Title: Hot-rolling thick steel plate on a four-high mill - using detectors to indicate start of gamma-alpha transformation
IPC: B21B37/74
Filed: 1974-02-08
Abstract: Process for controlling hot-rolling in a rolling mill producing thick products, esp. thick plate in steels which gamma - alpha transformation during cooling, and where the temp. of the Curie pt. is above the gamma - alpha transformation temp. for the conditions of rolling. The novelty is that after each rolling pass the product is inspected on both sides of the rolling mill by sensors which induce eddy currents in the metal in order to detect the moment where the gamma - alpha transformation start. The rolling conditions are then controlled so that this transformation only occurs in accordance with the programme required, i.e. after the last pass during rolling, or during cooling after rolling. Hot-rolling thick plate on four-high mills. The gamma - alpha transformation temp. depends on steel compsn. and rate of cooling, but this process permits its accurate detection.

Title: Rotary IC engine with four cavity rotor - has annular end rotor seals joined to axial rotor seals
IPC: F01C19/02
Filed: 1974-03-28
Abstract: The rotor is so shaped as to form four chambers within the casing. The chambers are separated by lip seals which are fixed to the rotor. The initial chamber connects with the inlet port which allows the combustion mixture into the engine under pressure. As the rotor revolves the charge connects with the spark plug which burns the mixture at constant volume. Further rotation of the rotor allows some of the gas to escape through the auxiliary port and increase the pressure in the preceding chamber, thus utilising some of the remaining energy in the gas. A second auxiliary passage repeats the process before the exhaust port is uncovered. The lip seals comprise linear (13-17) joined to the inner annular seals (10, 11) of pairs of annular end seals (9-12).
