Title: Cartridge for a sporting rifle - plastic end has concave outer face and central passage to interior
IPC: F42B5/307
Filed: 1974-06-28
Abstract: A cartridge for a sporting rifle has base (3) of plastics material, with a hole (5) through the middle and which fits inside the tubular casing, and which has a slight taper on its outside. The outer face (11) is dished or slopes at an angle of between 7 deg. and 10 deg. to its transverse section.

Patent FR-2314896-A1 (FR)
Title: Mixed ion-exchange resin bed for ultra purification of water - with two exchange resins sepgd. by inert interlayer
Inventor: WOLFF JEAN-JACQUES
IPC: B01J49/00
Filed: 1975-06-19
Abstract: A bed for the ulta-purification of water comprises an anion exchange resin and a cation exchange resin together with at least 2% by volume, based on the total resins, particles of an inert material. The dimensions of the particles and the specific masses of the resins are chosen so that when the particles are raised by a liquid flow, the inert material forms an interlayer separating the resins. The bed is used for purifying water e.g. for nuclear reactions which desirably require a content 1.5 ppm of Cl ions and below 1 ppm of Na ions. A two layer bed with anions and cation exchange resins of different densitiesiis used at present. Because of poor sepn. of the resins in use, optimum regeneration of the bed is not possible. The above enables perfect sepn. of the resins and optimal regeneration gives Cl and Na concentrations in the purified water lower than can be achieved by present ion-exchange beds.

Title: Compacting plastic bottles, etc. for recycling - by drawing them through a rotating nozzle to subject them to torsion and traction
IPC: B29B17/00
Filed: 1975-07-18
Abstract: The process comprises introducing the neck of the bottle into a rotating nozzle so that it can be grabbed by a clamp on a pivotal arm. As the arm pivots it pulls the bottle through the nozzle os that the bottle is subjected to a torsional and a longitudinal force. The amplitude of movement of the arm is longer than the length of the bottle. Handling and reprocessing of the bottle is simplified, compared with using a press to compact them. Pref. the nozzle has a polygonal aperture and pref. the clamp also rotates.

Title: Conductivity cell for particle analysers - measures electrolyte resistance variations by amplified voltages in direct proportion
IPC: G01R27/22
Filed: 1976-01-19
Abstract: An outer glass tube (11) has a microscopic pore (14) and an inner glass tube which can be filled with electrolyte via a valve at its outer end (26). An electrical potential (30) is applied to electrodes placed in the container (32) and in the neck of the inner glass tube (31). A third electrode (33) is situated in the upper half of the outer tube (34) and is connected via a capacitor (40) to an amplifier (36). The upper end of the outer tube is placed under vacuum.

Title: Sail mounting for boat - has forward sails formed in sections and rotatable concentrically about mast at different radii
IPC: B63H9/06
Filed: 1976-06-09
Abstract: The sailing boat has the forward sail on each mast formed as individual sails rotating concentrically to the mast, but at different radii. This allows these sails to be set at any angle through 360 deg. under the wind, and the rigging of the jib to be transformed, so that either the individual sails form one giant one, mounted edge to edge, and with the minimum angular area, or are opened up. Intermediate settings are possible by causing the sails to overlap for various amounts. The curves through which the sails are adjustable can be for between 80 deg. and 200 deg., extending equally to port and starboard.
Patent FR-2361143-A1 (FR)
Title: Dry hot compressed air for blast furnace - produced using heat exchanger and dehydrator assembly upstream of hot air furnaces
IPC: C21B9/16
Filed: 1976-08-11
Abstract: The air passage between a blower and hot air furnaces for a blast furnace incorporates a dehydrater assembly having a gas permeable rotor impregnated with a regenerative hygroscopic substance and a cooler for condensing the moisture in the air. a heat exchanger is arranged in the passage so that some of the hot compressed air coming from the blower can transfer its heat to the dehydrated air coming from the dehydrated assembly. All the air to be introduced to the hot air furnaces is passed through the dehydrater assembly and the heat exchanger and is dehydrated. It is unnecessary to supply any external hot air to regenerate the rotor. The moisture content of the treated air can be reduced without any significant loss of temp. and pressure. Air leakage between the regenerating and dehydrating zones in the dehydrater is prevented by sealing clearances with packing elements and externally introducing dry pressurised air into the sealed spaces.

Title: Converting water into hydrogen and oxygen - esp. for utilising waste heat from nuclear reactors
IPC: C01B3/06
Filed: 1977-02-25
Abstract: Process for decomposing water into hydrogen and oxygen comprises (1) reacting iodine with water and H2SO3 to form HI and H2SO4; (2) decomposing the HI into H2+I2; (3) decomposing the H2SO4 into H2O and SO3 e.g. via Fe2O3 or CuO; (4) decomposing the SO3 into SO2+O2 and (5) reacting the SO2 with water to form further H2SO3. Pref. stage (2) is operated at 400-900 degrees C, stage (3) at around the b.pt. of H2SO4 (nearly equal 300 degrees C) and stage (4) is conducted at 500-900 degrees C in the presence of a catalyst such as V2O5 or Pt. Stage (2) may be accomplished by reacting HI with Fe2O3 to form I2, FeO and H2O, and the FeO is reacted with H2O to form Fe2O3 and H2. Process is esp. useful for converting surplus heat, e.g. from nuclear reactors, into a useful fuel source. Process has less technical difficulties than decomposing water by electrolysis.
