Patent FR-2211178-A1 (FR)
Title: Plastic mould for mfr. of soft cheeses - with moulded base drainage grid
IPC: A01J25/13
Filed: 1972-12-27
Abstract: Mould comprises a cylindrical base portion and an inter portion. Both parts are made from a plastic matl. which is completely resistant to milk prods. The lower portion is moulded with a base which forms a grid consisting of parallel, highly tapered blades. These are triangular in section with the summit facing downwards, to facilitate the flow of the whey. The first drainage phase is much better effected in the new mould than in the old type; there is no risk of the formation of pockets of whey against the side walls and when the mould is turned over there is no sticking at the edges, because the pasty cheese slides freely over the plastic walls. For use, the curds are poured into the superimposed parts of the mould; the whey drains through the grid. After the first drainage, the bases are placed on any surface which can canalise the liqs. which drain out. The two parts of the mould are then turned over together, bringing the base to the top; as the compaction is practically equal to the height of the lower part, this can now be withdrawn. The upper part is turned over again and this phase is followed by de-moulding.

Title: Explosion prevention in heat exchanger - partic useful for hydrocarbon vaporisers
IPC: B01D3/42
Filed: 1974-02-13
Abstract: A safety device prevents an explosion occuring through flammable gas escaping from a hydrocarbon vaporiser, into the stream of heat transfer fluid circulating through the heat exchanger of the vaporiser, and thus coming into contact with the flame of the heater. The device consists of two separators and a max. press. manostat. The separators are connected respectively on each side of the vaporiser, in the pipe carrying the heat exchange fluid, between the vaporiser and the heater. The manostat is connected into the pipe between one of the separators and the heater. If the press. rises through accidental leakage of hydrocarbon into the stream of heat exchange fluid, the manostat acts to stop the flow of the stream and to isolate the vaporiser and the separators by two electropneumatic valves. The separators have purge valves and level indicators. The device ensures the automatic protection of the heating circuit against any accidental entry of hydrocarbon into the burner zone.

Title: Laser proximity detector for flying vehicle - obtains position of target and discriminates between various target surface areas
Inventor: KOCK SIEGFRIED
IPC: G01S17/06
Filed: 1974-10-08
Abstract: A laser proximity detector in a flying vehicle is used to measure the distance from a target. The detection is independent of the nature and reflecting properties of the target surfaces. This system discriminates between a plane target area and pseudo targets such as a cable or mast. An optical proximity detector is mounted in the nose of a missile and comprises a laser emitter and receiver mounted in an enclosure. A beam from the emitter is focussed by a lens and has a small angle of divergence from the perpendicular direction. Energy reflected from a target is returned to pass through optical lenses to photodiode detectors. These are mounted at a predetermined distance behind the emitter. The diode send electrical signals to a processing circuit (6) which determines the ratio between the signals in order to obtain the target position.

Title: Container leakage detecting appts. - measures time taken for specified pressure change after creating reduced pressure by releasing pressurised fluid
IPC: G01M3/32
Filed: 1975-10-08
Abstract: A thermodynamic process is used to detect leakage of a container. Cooling is produced as a fluid under pressure enters a container to create a reduced pressure in the space between container and sealed envelope. The time for increase of pressure is measured. A sealed container (1) is in communication with an exterior envelope (2) whose external boundary (3) is perforated and blanked by a flexible membrane (4) carrying an electrical contact (5). A spring (6) pressed against the contact which operates in conjunction with an adjustable contact (8) to close a signalling circuit. Cooling produced by releasing air under pressure creates a reduced pressure region to move the membrane against spring action to close the electrical circuit within a time period. This period is increased when leakage is present.
