Patent FR-2311087-A1 (FR)
Title: Desulphurisation of coal - by heating in contact with a gas contg nitrogen dioxide to oxidise sulphur cpds
IPC: C10L9/06
Filed: 1975-05-12
Abstract: The desulphurisation of coal is carried out by (a) heating coal particles to 100-500 degrees F, and (c) contacting the hot coal with a gas contg. NO2 (rest non-reactive components) to selectively oxidise the S cpds. in the coal, forming oxidised S cpds. (sulphates and sulphites) and gaseous S cpds. which are readily separable from the coal. High degrees of desulphurisation (e.g. 56-87%) can be achieved; saleable H2SO4 can be obtd. as a by-prod.
Patent FR-2311271-A1 (FR)
Title: Portable antitank weapon using shells with velocity boosters - involving strip explosives, a filament wound firing tube and sundry foam components
Inventor: ARENE FRANCOIS
IPC: F42B5/16
Filed: 1975-05-16
Abstract: Weapon comprises a firing tube for accepting and aiming shells fitted with an integral velocity booster cartridge and with a support to fit the rear of the firing tube. The firing tube is strong enough to withstand radial pressures released via the walls of the booster pack, which are of semi-open construction. Prod. may be carried aimed and fired either manually or with supporting devices, opt. including automatic aiming and aim correction controls. The shell may include gyrostabilisers and other flight controls. As a weapon system it combines the merits of a recoil-less cannon and of a rocket launcher, by firing a shell at a supersonic speed with some in-flight acceleration without submitting the launching personnel to a heavy recoil or a high nozzle crack (noise) and without much tell-tale evidence of the firing position. The barrel construction provides a combination of durability, strength and light wt. The form of the explosive charge minimisers pressure differentials during acceleration within the firing tube, thus avoiding serious stress differentials in the tube and providing reproducible shell flight characteristics.

Title: Moulding of materials based on cement - where all mould surfaces are coated with water-tight plastic foil
IPC: B28B7/36
Filed: 1975-06-13
Abstract: Moulding a block of cementitious material in which all the internal surfaces of the mould are coated with a watertight plastic material presenting a smooth, glossy finish, the mould then being filled with the cement-base material. Where necessary, cores or inserts may be used to provide holes in the moulding pref. by employing expanded synthetic plastics coated with a water-tight, smooth plastic where they are in contact with the material being moulded. The water-tight, platic may be applied by painting or by using a plastic foil fixed by an adhesive and the pref. mould and any inserts are thus entirely covered by plastic. Used e.g. for moulding blocks of refractory concrete used for the wall of boiler flues in which carbon is burnt, providing an ideal surface on the blocks.

Title: Advertising leaflet with detachable coupon - consists of envelope with easily torn-off edge, enclosing third sheet
IPC: B65D27/34
Filed: 1977-05-06
Abstract: The use of advertising leaflets which are enclosed in newspapers or magazines is widespread. This type of leaflet usually includes a tear-off coupon which the recipient is asked to fill up and return. However evese coupons are often difficult to detach and so are less likely to be used.

The two outer sheets are torn along the perforated line (18) near the gummed edge (14). This enables the inner sheet (13) to be easily extracted and then torn off the gummed edge (15) along the perforated line (18).
Patent FR-2350919-A1 (FR)
Title: Electrodischarge machining using travelling wire electrode - where wire is oscillated at high frequency to increase rate of machining
IPC: B23H7/02
Filed: 1977-05-16
Abstract: A conducting workpiece is machined by spark erosion using a travelling wire electrode, where the workpiece moves at 90 degrees w.r.t. the axis of the wire to form a gap fed with a liq. A sequence of electric pulses is applied to create a discharge in the gap, thereby removing material from the workpiece; and the electrode wire is oscillated at min. 100 Hz during spark erosion. The pref. frequency of wire oscillation is 1-50 kHz, with amplitude 1-50 (1-5) mu m. In the pref. machine, the wire travels under tension between two guides, and a vibrator is located near one guide to oscillate the wire. The pref. working liq. is water with specific resistance 5 x 102 to 5 x 104 ohm. cm.; a coolant may also be fed to one of the guides. The plane of wire oscillation pref. coincides with the cutting direction of the wire, and an oscillation parameter may be periodically altered. For accurate machining, the wire dia. is usually 0.05-0.5 mm., which previously limited the voltage which could be applied, as the wire broke due to arcing or short circuits. Oscillation of the wire interrupts arcs or short circuits, and also reduces friction of the guides, so wire breakage is eliminated and the rate of material removal is increased.

Title: Sterilising ion exchange resins using bactericidal salt soln. - prepd. from salt pastilles contg. isolated bactericide inside
IPC: B01J49/00
Filed: 1977-06-01
Abstract: The ion-exchange materials used for water softening are treated with a sodium chloride soln. circulated through the material, the soln. being prepd. by percolating water through a mass of sodium chloride in which has been incorporated >=1 bactericide. The bactericide is present as sodium chloride pastilles in which it is enveloped in a manner such that it has no contact with the exterior. The sterilising agent comprising a pure bactericide, or one premixed with NaCl, contained in the NaCl pastilles is novel. The NaCl soln. is used for regenerating the ion exchange resin. The use of chlorine contg. bactericides, such as chloramine T, results in hydrolysis with moist air contg. reducing the efficiency and also polluting the atmosphere. By using the pastilles this problem is avoided.

Patent FR-2399362-A1 (FR)
Title: Liquid container with discharge opening - has closure securable to container with movable discharge tube
IPC: B65D47/06
Filed: 1977-08-03
Abstract: A liquid container (19) has a closure (20) and an outlet tube (26) which extends through the discharge opening (25) of the container and is displaceable between two positions. In the first position it extends into the container and permits closure of the opening, and in the second position it extends outwardly to act as a discharge tube. The tube has an external flange (27) which, in the first position, forms a first seal around the opening and a second seal against the closure. During release of the closure the first seal is broken before the second seal so that an over-pressure in the container prior to the release does not force liquid out through the tube.
