Title: Bolt locking coil spring in nut - extends along annular nut groove and projects into nut bore
Inventor: LATOUR CLAUDE
IPC: F16B39/34
Filed: 1975-04-02
Abstract: The nut (1) is used to prevent loosening of assemblies screwed or similarly held together and has an annular groove, perpendicular to the axis and with a semicircular bottom face. An annular spring (2) in this groove is made of wire wound spirally, and it projects into the nut bore and grips the bolt. As the bolt is turned the spring turns lie over at an angle offering least resistance to bolt passage. If the bolt tends to turn in the opposite direction, the spring turns attempt to re-orientate themselves and prevent relative motion between nut and bolt.

Title: Soap tablet wrapping machine - has vertical guide tube in which pivoted arms draw strip under tablet
IPC: B65C9/14
Filed: 1975-04-30
Abstract: A wrapping machine for tablets of soap has the tablets (13) delivered individually by a conveyor (1) and lifted by a reciprocating piston (3) into a vertical guide tube (8) pulling with them a section (4) of the flexible wrapping strip. Arrival of the strip is synchronised with the tablets. The strip is then wrapped round the top of the tablets. Mounted on the guide tube are two pivot arms (9a, 9b). These pass through slots in the side of the tube. As the piston pushes a tablet upwards, the arms draw the strip down round its sides and underneath it. In this way a pile of tablets is built up inside the tube. There is a side exit and an ejector piston at the top of the guide to expel the tablets.

Title: Dialyser for balance dialysis of small vol. samples - can measure diffusion of small molecules through membrane trapped between two recessed plates
IPC: B01D61/28
Filed: 1975-05-05
Abstract: Two plates with recesses machined into them are bolted together so that the recesses are opposite each other. A median membrane is trapped between the 2 plates sepg. the recesses. Fine holes are bored through each plate to reach the recess of the plate. Alternatively the membrane can be trapped between 2 plates made of fluorinated material, each plate pierced with holes. The whole lot is then enclosed by aluminium alloy plates also pierced with holes that are concentric to the holes in the fluorinated material plate, but larger in dia. These holes can form incubation chambers that are open but able to be sealed by adhesive tape. The plates are used in biochemistry for e.g. enzymology; in medicine for e.g. immunology and in the chemistry of macromolecules. This assembly is simpler than current appts. and improves the accuracy of measurements.

Patent FR-2356072-A1 (FR)
Title: Safety system for e.g. crimping machine - uses light beams with photo-electric cells on sides of work to stop machine when light beam is broken
IPC: F16P3/14
Filed: 1976-06-23
Abstract: Machines used for crimping electrical connectors are a source of danger due to the possibility of the operator's fingers being trapped. The usual type of guard is not very effective, since it often obscures the operator's view. To overcome this difficulty, it is proposed to use a light source which emits two beams of light on either side of the work. The light beams are received by photo electric cells. In the event of the operator's fingers being too close to the work when the machine is operating, the light beams are intercepted and the machine is switched off. If necessary, more than one light source and more than two photo electric cells may be used, and the principle can, of course, be applied to other types of machine.
Patent FR-2357294-A1 (FR)
Title: Filter with integral spray nozzle cleaning system - using water to move the nozzles backwards and forwards along the filter
IPC: B01D46/42
Filed: 1976-07-08
Abstract: A filter with an integral cleaning system is described. The washing system comprises spray nozzles on a tube connected to the water supply. The tube with the nozzles is moved on a carriage to and fro along the length of the filter, being supported on a horizontal rail parallel with the top of the filter case. The traction is provided by means of a hydraulic motor which is integrated with the cleaning fluid circuit. The motor may either be stationary and linked to the movable carriage by means of a chain transmission or may itself be mounted on the carriage. The system eliminates the use of an electric motor and the electric circuitry necessary to produce the directional changes needed at each end of the rail. This means that the difficulties of operating an electric motor so close to spraying nozzles and the periodic maintenance necessary to an electric motor are removed.
Patent FR-2322680-A1 (FR)
IPC: B21D24/00
Filed: 1976-09-03
Abstract: The invention proposes production of lightweight containers from a metal/plastic composite sheet, in which the sheet (1) is given depth by stretch-forming by means of a punch (10). A relatively large depth is achieved by means of a punch (10) which, next to its end surface (31), has at least one offset shoulder edge (27, 28, 29), with the result that, when advancing, first of all only the end surface (31) acts on the sheet (1) and only later does the shoulder edge (27, 28, 29) come to bear on the inclined wall of the preform. By virtue of a friction fit, the shoulder edges (27, 28, 29) help to expand the sheet in a uniform manner.

Title: Ethylene prodn. from higher paraffin(s) - by hydrocracking and steam cracking
Inventor: FRANCK JEAN-PIERRE
IPC: C10G69/06
Filed: 1976-10-04
Abstract: Prodn. of ethylene comprises hydrocracking (hydrogenolysis) of ahydrocarbon feed boiling in the 0-360 degrees C range an and contg. >=10 wt. % C4+n-paraffins and >=10 wt. % C4+ isoparaffins, followed by steam cracking at the C2-3 prod. Hydrocracking is carried out in a series of >=2 reaction zones each operating at 300-550 degrees C, 10-150 bars, LHSV of 0.2-5 and an H2/feed ratio of 300-3000 Nl/l. The temp. in each downstream zone is 5-25 degrees C higher than that in the preceding zone. The 1st zone contains an acidic mordenite catalyst contg. 0.01-25% of Ni, CO and 1 or Fe. The downstream zone(s) contain(s) a catalyst comprising 0.01-25% of >=1 Pt-group metal on a support comprising SiO2, Al2O3, SiO2-Al2O3 or a zeolite. The effluent from each hydrocracking zone is fractionated into an H2 stream, a CH4 stream, a C2-3 fraction (ethane + propane) and a C4+ fraction. Each C4+ fraction is passed to the next zone or, in the case of the last zone, is recycled to >=1 preceding zone. THe C2-3 fractions are combined and passed to a steam cracking zone. Steam cracking is carried out at 700-850 degrees C, 1-1.4 bar, a residence time of 0.2-1.2 sec and an H2/hydrocarbon wt. ratio of 0.25-0.4. cf. process employing one-stage hydrocracking with steam cracking of the total effluent, the process gives higher ethylene yields (e.g. 46.6% cf 42.9%) and reduced CH4 formation (e.g. 36.2% cf 40.4).

Title: Metal fires extinction with expanded graphite - prevents metal flow and gives rapid extinction
IPC: A62C3/06
Filed: 1976-11-22
Abstract: Fires caused by metals such as alkali metals esp. Na and certain light metals Al and Mg which have ignited are extinguished by applying expanded graphite, obtd. opt. in situ, to exclude the atmos. Alkali metals used in nuclear power stations as thermal carriers which ignite can be extinguished irrespective of the type of metal and its state and the temp. of the fire. The sponge-like graphite fixes the liq. alkali metal and prevents it from flowing as well as preventing contact with the atmos. The amt. of graphite complex is surprisingly small to achieve extinction.
Patent FR-2376253-A1 (FR)
Title: Reinforced concrete bridge construction on piers - has part of shuttering and support work used as concrete reinforcement
Inventor: RICHARD ANDRE
IPC: E01D4/00
Filed: 1976-12-31
Abstract: An inverted soffit in two sections is first put into position. One section forms the permanent structure reinforcement and is eventually cast into the concrete and the other is an external section. Shuttering is then put in place and the permanent reinforcement is cast into the concrete. Once the concrete has set, the external part of the soffit support structure is dismantled. The supporting structural reinforcements consist of a series of trellises the same shape as the girders of the bridge which are in turn supported on permanent piers. The external part of the soffit which is located above the supporting reinforcement should preferably consist of trellises whose individual sections are connected to those sunk in the concrete in order to form a structure which is sufficiently rigid to overcome any formation of the soffit under the weight of the newly poured concrete.
