Patent FR-2286560-A1 (FR)
Title: RF coupling device for car radio - has loop formed on window and collecting parasitic currents from car body
Inventor: MOTHIRON CLAUDE
IPC: H01Q1/12
Filed: 1974-09-24
Abstract: Parasitic currents in a car body are collected by a loop (16) attached to a car window (11) connected to the car body (29). Connection to the radio is by a twisted pair of wires (21). Low impedance minimises pickup from ignition permitting unscreened connection, particularly if the rear window is used. Alternative configurations have a single wire to reduce obscuration in windscreen of a rear-engined car, and the use of a rear window heater as the collection loop, with choke/capacitor coupling to reduce impedance. Loop wire can be deposited on window or on a plastic sheet attached to the window or embedded in glass, and may be on same window as heater.

Title: Throwaway package for drink - has container with foot around filler neck and pull off cap at opposite end
IPC: B65D41/16
Filed: 1974-10-01
Abstract: The container (1) has one end narrowed down to form a neck (3) used for filling. At this end is fixed a foot (2) which is a tapered circular sleeve projecting beyond the neck. The other end has an annular groove (6), just below its edge, providing a location for a rib (7) on a flat cap (4) closing off this end. During the filling operation the container is positioned on its cap end and after filling, the neck is permanently sealed by a cap (5). To use, the cap is pulled off by means of a pull tab (8) and the container rests on the foot.

Title: Engine operating on mixture of fuel and water - utilises carburettor depression to inject spray into inlet manifold
IPC: F02M25/022
Filed: 1974-12-05
Abstract: A pipe (G) from a water tank leads into a pipe (E) which is connected to the carburettor at a point (C) near the plane of the butterfly plate so that even when the butterfly plate is slightly open, the depression in the carburettor causes water to flow through the pipe (G) and form a fine spray in the pipe (E) at the point (F). The other end of the pipe (E) is connected to the fuel tank (N) filler pipe at a point (H) just below the filler cap (J). The depression in the carburettor then sucks in a mixture of water and petrol vapour which mixes with the air and the fuel from the float chamber (A).

Title: Counter-thrust nozzle mounting for rocket - has heat resistant rubber sleeve slidable in nozzle tube and screwed to base
Inventor: LACOSTE P
IPC: F02K9/76
Filed: 1975-01-29
Abstract: When a space satellite is ejected from its rocket it is necessary to retard the rocket until it is clear of the satellite orbit by using counter-thrust nozzles mounted on the rocket nose. Since the rocket nose deflects under variations in internal pressure, a flexible mounting is provided between the divergent part (4) of the nozzle and its base (9) which is attached to the rocket nose (2). The mounting consists of a sleeve (5) of heat resisting rubber, one end (6) of which slides in the nozzle tube (3), and the other end is attached by the screwed fitting (8) to the base (9). alternative designs use rubber bellows provided with metal reinforcing rings.

Title: Air-to-air heat exchange - gives greater exchange where currents are parallel
IPC: F24F13/30
Filed: 1975-06-03
Abstract: Heat is recovered from one current of air in order to warm another at lower temperatures, both currents being created by blowers, using plate-type heat exchangers. In the latter the currents initially intersect, then flow parallel to each other in opposite directions, and finally intersect againt. The structure of the heat exchanger plates is such as to aid heat transfer between parallel currents and not when they intersect. The exchange surfaces can be greater where the currents are parallel, and where they intersect plate material thickness can be increased.

Title: Machinery for welding the edges of fabrics together - comprises travelling carriage which moves along the selvedge
IPC: B29C65/00
Filed: 1976-08-09
Abstract: The machinery for welding a crinoline strip onto the edge of a fabric consists of a long flat table with a heating strip along one edge on which the edge of the fabric is placed. A carriage moving on overhead rails, lays firstly a film of adhesive material along the edge of the fabric and then places the crinoline strip on top. This is followed by a jet of hot air to preheat the crinoline strip and then by a heated wheel, which applies sufficient heat and press. to weld the crinoline strip onto the edge of the fabric. Finally a cutter and cutter guide working in a slot along the edge of the table cuts off the excess material. The machinery enables very wide fabrics to be welded and is suitable for fabrics which cannot be conveyed by a moving belt.

Title: Detection of poisons of microorganisms in effluent - sensitively and in a few minutes to protect treatment plant
IPC: G01N33/18
Filed: 1976-08-10
Abstract: The presence of material which would slow growth of bacteria in effluent is detected by measuring the rate of disappearance of dissolved oxygen in a sample which has been oxygenated and inoculated with bacteria. The measurement is made with an electrochemical oxygen meter. The steps in the test are as follows: (A) Measured quantities of effluent, diluent water and bacteria source are charged to separate measuring tanks. They are held at the required temp. and air is bubbled through all the tanks for a predetermined time. (b) The diluent and bacteria source are run into a stirred fermentor at the same constant temp. and air is bubbled through the mixt. for a predetermined time. (c) The effluent is run into the fermentor. The air supply is stopped and the vessel is sealed from the atmos. The amts. of effluent and diluent are chosen so that the bacteria added are sufficient for the bacterial activity can reach its maximum value. The oxygen and demand is greater than the total oxygen available in the fermentor. The rate of oxygen used is small enough for equlibrium to be maintained between the liq. and gas phases in the fermentor. A meter is used to determine either the fall in oxygen concn. in the liquid in a given time or the time taken for a given concentration drop. The average rate of oxygen use is calculated. The actual rate is compared with that for a similar procedure with a poison free nutrient substrate replacing the effluent. The method is sensitive to small amts. and takes only a few mins. to give a result.

Title: Opener for flat or curved oysters - has lever operated piercer and has screw to section holding muscle
IPC: A47G21/06
Filed: 1977-03-16
Abstract: The device is intended to open oysters without effort. A lever (1) supports in its centre the main grasping device composed of an outer part (3) the extremity of which ends in a hollow punch. Inside this punch the piece (4) whose upper part is a helicoidal screw slides freely. By a vertical pressure on the lever (1) the shell of the oyster is pierced. A second and simultaneous pressure of the fingers on the lever (2) makes the steel point come out of the punch. This steel point is curved and takes up a semi-horizontal position and effects a total rotation with the help of the helicoidal screw, sectioning the muscle that holds the oyster closed. The device opens with equal facility flat Belon oysters and hollow Portuguese oysters.
