Patent FR-2249734-A1 (FR)
Title: Process and machinery for slitting strip metal - has one edge profiled direct from wider strip
IPC: B23D19/06
Filed: 1973-11-05
Abstract: The process relates to the manufacture of strip with a profiled edge for use in forming floor grills. Wide strip material is uncoiled from a stock roll in the direction of the arrow to pass in a horizontal plane between slitting discs. The slitting discs on the shaft are below the strip. The slitting discs on the shaft are above it. Grooves are cut in the face of the discs and the top of the circumference of a disc just intermeshes with the bottom of the circumference of a disc. Thus as the strip material passes between the opposing pairs of discs the edge is sheared to shape. Plain edged discs may be used in addition to make the cuts so providing several strands of strip plain on one edge and profiled on the other, at the same time.

Title: Treatment of effluents from animal rearing units - to give fertilizer products and reusable water for cleansing units
IPC: C02F11/12
Filed: 1974-02-11
Abstract: A process for the continuous treatment of effluents from cattle rearing units comprises coarse filtering the effluent, subjecting the filtrate to coagulation/flocculation, filtering suspended matter under pressure, concentrating the filtrate by evapn. and deodorising the distillates and gases evolved. Large volumes of effluent contg. higher concns. of organic matter than those from domestic sources may be safely treated. The process yields material useful as fertilizer and 80% of the water used to wash the floors of the units may be recovered and reused.

Title: Brake shoe wear indicator system - uses two embedded electrodes which are shorted when wear limit is reached
IPC: F16D66/02
Filed: 1974-02-13
Abstract: The two electrodes (15A, 15B) are embedded in a plug of non-conducting material (12), the plug being supported in the backplate (10) of the brake assembly. The plug and electrodes protrude into the brake pad so that when wear reaches a given level the electrodes are shorted out, and an indicator activated (18 to 22). Using two electrodes helps reduce the chances of accidental activation of the system, and can allow for uneven wear patterns. Two plugs can be used, each with one electrode. The electrodes can be simple wires, perpendicular to the face of the pad, or parallel to the face. One electrode can be placed to form a loop round the other.
Patent FR-2265513-A1 (FR)
Title: Processing high nitrile polymers - formation of packaging films for environmentally sensitive matl. e.g. foodstuffs, medicines etc.
IPC: B29B13/06
Filed: 1974-03-29
Abstract: Ploughs are continuously rotated within a heated cylindrical processing chamber containing a moist batch of high nitrile resin particles of broad size distribution, to establish a converging mixing pattern and repeatedly force portions of the batch upwardly along the surface of the chamber while vaporising at least some of the moisture. Portions of the resin are diverted in the opposite direction from the converging pattern to increase the surface exposure of the particles, without fusing them together. A low pressure gas is circulated through the particles to purge the vaporised moisture and entrain a portion of the smaller particles from the chamber. The particles are dried without degenerating the polymer.

Title: Catalyst for converting ammonia to nitrogen dioxide - obtd. by decomposition of cobalt nitrate mixed with other nitrates
IPC: B01J23/89
Filed: 1974-05-31
Abstract: Process for mfg. and regenerating solid porous catalysts, used for the oxidn. of ammonia in the presence of air, by the spraying at a controlled temp. above the decompsn. temp., of a decomposable molten mixt. or soln. of nitrates consisting of cobalt nitrate with at least one cpd. selected from the nitrates of Ce, Mg or Fe. The mixt. is pref. subjected to pressure to obtain a fine spray or a hot oxidising or neutral carrier gas may be used; the mixt. may contain trace amts. of promoters consisting of metal- salts or -acids in the liq. state, esp. of Pt. Decompsn. of the mixt. may occur on a heated support and regeneration of a catalytic bed can be achieved in situ in a reactor. This catalyst provided a yield of 96% NO2 as compared with 94% by a known process, and catalyst can be regenerated with virtually no interruption to prodn. and with substantial savings in cost.
Patent FR-2280889-A1 (FR)
Title: Weighing out components of mixtures - in variable quantities and proportions avoiding calculations for different total quantities
IPC: G01G19/26
Filed: 1974-08-01
Abstract: An appts. for weighing mixts. consists.. of a steelyard balance with one or more beams and cursors. Each beam has several series of graduations. Each series is calibrated in parts of a specific quantity of mixt. The graduations of one series on a beam are to one scale and the others on that beam are multiples of that scale, whole or fractional e.g. 1, 2, 4 to allow different quantities of mixt. to be weighed. The graduations of the scales on successive beams are multiples e.g. 1, .1, .01 to allow finer weighing. The beam may be a hollow tube, with a longitudinal opening, in which is a rotatable cylinder carrying graduations each corresponding to a quantity of mixture. The cylinders may be coupled mechanically by gears so that they can be turned together by a knob to display the required series in the openings. The balance allows the operator to weigh out the components of a mixt. in a given order without having to calculate the amts. of the individual components for a given total amt. of mixt.

Title: IC engine carburettor with ball valve fuel pump - has ball valve opening to vent injector during no acceleration
Inventor: PAULMIER CLAUDE
IPC: F02M7/08
Filed: 1974-09-20
Abstract: The throttle valve which is operated by the accelerator pedal has a crank attached to the valve spindle. The end of the crank carries a spring loaded link which moves a bell crank lever bearing against a spring loaded piston. The piston operates a diaphragm pump. The diaphragm discharges fuel through a discharge passage which is connected to the fuel in a float chamber by a fuel inlet ball valve. The discharge passage is also connected to a fuel injector by a fuel outlet ball valve being connected to atmosphere by a third ball valve. During no acceleration the third ball opens to the injector and prevent fuel being discharged due to high pressures in the engine inlet.

Title: Offset press moistening appts - uses gas jet to project liq from stirrer to transfer cylinder
IPC: B41F7/30
Filed: 1975-01-31
Abstract: A stirrer works in a basin full of the moistening fluid, and there are one or more transfer cylinders, clear of the stirrer, and between it and the cylinder carrying the printing blocks. The stirrer (16) has a component on its surface retaining the fluid on it as it rotates in the basin (17), and in which orifices are formed. A jet of gas (20) is directed onto the stirrer surface so as to form a chord near its periphery, near the interval between it and the nearest transfer cylinder (15). This blows the fluid retained in the orifices against other parts of the stirrer, from which it rebounds and is deposited on the transfer cylinder. The interval between stirrer and cylinder can be less than 12.7 mm.

Title: Plastic transport bag for cut flowers - has inflatable internal collar for retaining small amount of water (AR200575)
IPC: B65D85/50
Filed: 1975-03-27
Abstract: A plastic bag provides a transport wrapping for cut flowers which can also contain some water to keep the flowers fresh. To prevent the water from flowing out of the bag when it lies on its side, the open bag end is folded inwards (22) to form an internal collar (13). A tubular ring (28), also made from plastic is fitted around the collar (22). After the stems (36) of the flowers are inserted through the collar and the water is added, the tubular ring (28) is inflated through an external nozzle extension (29). The flowers are thus held in a required position inside the bag and the water is prevented from escaping through the collar.

Title: Visual vehicle engine performance indicator - displays engine speed and throttle opening on same dial for driver
IPC: F02B77/08
Filed: 1975-05-28
Abstract: An engine performance indicator for a vehicle driver employs a display panel (8) so that the driver can see at a glance the engine speed and throttle opening. He is then able to take the appropriate action of altering the throttle opening or changing gear for optimum engine performance. An electronic sensor (9) measures the frequency of the ignition impulses of the sparking plugs (2) of the engine (1). A voltage proportional to this frequency is transmitted to a galvanometer (6). The angle (alpha) of the opening of the throttle (4) of the carburettor (3) is measured by a potentiometer (12) which transmits a voltage to a second galvanometer (7).
