Patent FR-2337249-A1 (FR)
Title: Tunnel lining cage for tunnelling machine - consists of double rings and spacers, with longitudinal members and tensioners
Inventor: OGER JACQUES FRANCOIS
IPC: E21D11/28
Filed: 1975-12-29
Abstract: The ring-shaped cage used in conjunction with a tunnelling machine consists of double rings (4a, 4b) matching the shape of the tunnel, kept spaced from one another by longitudinal struts. Further, one ring (4a) is kept spaced from the other ring (4b) of each pair by bridging clamps with a bolt passing through, or alternatively big sections of rods welded between them, or by special straps locked by wedge shaped keys. As the tunnelling machine is advanced, a fresh double ring can be added, and tensioned against the tunnel wall. The double ring segments can be joined by an adaptor consisting of two blocks (20) with flanges (15) which are bolted together, with an upright (18) to fit the ends of the rings (4a, 4b) against which they are gripped by a U shaped bridge (12) secured by a through bolt (7). A wedge (22) can be fitted into a sloping slot (21) between the flanges to expand the ends.

Title: Valve for dispensing liquids, semi-liquids and aerosols - is actuated by lever mounted on flexible diaphragm and formed with fork engaging collar on valve needle
IPC: B65D83/16
Filed: 1976-01-19
Abstract: The valve (1) for dispensing liquids, semi-liquids or aerosols has a tapered needle (2) with a pointed end (8) which sits in a conical seat (7). The needle (2) is guided partly by ribs (16) in the front housing (5) and partly by ribs forming a cross (9) in the rear housing (10). A spring (12) keeps the valve on its seat. The valve is opened by the L-shaped lever (3) which is formed integrally with the flexible diaphragm (4). Pressing the lever arm (15) downwards causes the fork end (14) to press against the collar (13) on the valve (2) and lift it off its seat (7). The lower part (6) of the housing is of a suitable shape to form a tight fit on the liquid or aerosol container.

Title: Core support plate - with cooling fluid passages provided with flow restrictors to produce laminar flow in the fuel assemblies
IPC: G21C15/02
Filed: 1976-01-30
Abstract: A core support structure for fuel assemblies in the core of a reactor, fixed to the lower end of a core sleeve enclosing the core and suspended in the reactor vessel, consists of a simple plate provided with a series of channels for the passage of the cooling fluid, extending vertically through it at each fuel assembly support location. Each of the channels has a throttling orifice at its inlet and a zone of greater diameter downstream of this orifice, such that the cooling fluid penetrating the channels experiences a pressure drop and the flow of the fluid leaving the channels is laminar so as to ensure a uniform flow distribution of the cooling fluid in the interior of the fuel assemblies constituting the reactor core. Simplifies the core support construction very considerably so that the number of assembly operations and the cost is substantially reduced.
Patent FR-2348284-A1 (FR)
Title: Aq. organic electrolyte soln. purification - by electrolytic removal of tin, used for treatment of tin-plated materials before melting treatment
Inventor: YOSHIDA MINORU
IPC: C25D3/32
Filed: 1976-04-15
Abstract: Known electrolytic Sn-plating process in which a material (e.g. Sn-plated steel strip) is treated with a soln. of an organic electrolyte (I) then subjected to an Sn-melting process is improved as follows: After use, the aq. soln. of (I) is regenerated by electrolysis (to deposit Sn metal and to maintain Sn concn. in soln. at 0.2-5 g/l.) then recycled. Inexpensive economical effectively recovers Sn with high current efficiency from (I) solns., and allows these to be recirculated. In an example, an aq. soln. contg. 8 g/l. of cresolsulphonic acid (as I) and 1.2 g/l. of Sn was electrolysed at 7 V/current density 5A/dm2. The current efficiency was 82%, and the sn concn. was kept at 0.9-1.2 g/l.
Patent FR-2357821-A1 (FR)
Title: Open fireplace system for domestic heating - has waterway in base under grate and back to provide hot water
IPC: F24B1/183
Filed: 1976-07-09
Abstract: The fireplace has a base and a backplate which are formed of two castings (3, 4) with a narrow gap between them leaving a thin space (5) which serves as a waterway. There is an inlet header (6) at the front of the base and an outlet header (7) at the top of the back. Water circulates between them by natural convection. The base and back have ribs (8) which project into the fire space and increase the heat transfer area. Logs (12) can rest across the tops of the ribs from the base leaving an ash pit space below them. The construction increases the heat transfer from the fire and thus improves the efficiency without obstructing the chimney and thus without reducing the draught.
Patent FR-2359575-A1 (FR)
Title: Irrigation system for large areas - has tractor powered by incoming water pressure to unroll and position irrigation hose from drum
IPC: A01G25/09
Filed: 1976-07-28
Abstract: The irrigation system is designed for large areas and uses a tractor carrying a drum of irrigation hose. The tractor and its functions are powered by the pressure of the incoming irrigation water. This drives an hydraulic motor which, in turn, powers the two front wheels of the tractor through a reduction unit. The single rear wheel is for steering and guiding the hose. The same motor also powers the drum for winding or unwinding the hose, a selector clutch being provided. A combustion engine may replace the hydraulic motor for driving the wheels, the motor powering the drum only.

Title: Prodn. of coinage steel - using a ferritic stainless chromium steel or special surface hardness and smoothness
Inventor: CHALK DAVID LLOYD
IPC: C22C38/18
Filed: 1976-11-15
Abstract: Steel for coinage is a cold-rolled, low-carbon, ferritic, stainless steel contg. C =0.03, Mn =0.50, P =0.04, S =0.02, Si =1.0, Cr 12-18, Ni =0.50 and Al 0.1-0.3 wt.%. The steel is not heat-treatable owing to its low C level. Ingots are hot rolled and box-annealed at 815-845 degrees C for >=1 hr. After annealing a surface layer of up to 0.07 mm is removed and the strip cold rolled, pref. in a Sendzimir mill, to 1.27-1.52 mm. The strip is then annealed in a continuous furnace in a H atmos. at 845-900 degrees C followed by pickling in an aq. soln. of 4-10 wt.% HNO3 and 1-2 wt.% HF. The surface hardness should not exceed Rockwell 8 of 75 and the surface should have a max. roughness of 4.06 x 10-4 mm in order to facilitate stamping and coining as well as to produce a coin with a lustre appearance and showing fine details and contours of the images. The actual metal value of the coin is less than its nominal value so that there is no risk that the coins will be used for purposes other than coinage.

Title: Exploitation of red mud obtd. from titanium ores - where mud is used as vitreous coating on steel, or in glass fibres or tiles
IPC: C04B18/04
Filed: 1977-08-18
Abstract: The ores contain iron titanate, and have a compsn. of up to 60% TiO2, 8-15% iron oxides, 1-10% alumina, and the oxides of Ca, Mg, Mn, Zr, Cr, V, Nb. The mud is obtd. by treating the ore with H2SO4, and is exploited by several different thermal processes. One pref. process is to spray the mud in a redn. plasma of H2 to produce a coating resisting corrosion, erosion and/or wear. In another pref. process, 50-60% of the mud is mixed with 14-18% lime and 30-40% sodium feldspar as used in glassworks, and melted at 1400 degrees C to obtain a vitreous mass used to mfr. fibres; cement contg. fibres, where the mud replaces asbestos; tiles; multicoloured coatings in buildings; or solar heat collectors with low emission of radiation. The melt can be sepd. into two phases, viz. a glass and a sponge(S) not melting at 1450 degrees C. Sponge (S) is rich in metals, and can be used as an addn. in mfg. special steels. Numerous prods. with a commercial value can be obtd. at low cost.

Title: Brake mechanism for a loom warp beam - automatically maintains constant wind-off tension in the warp yarns by controlling tension in brake band from yarn winding dia.
IPC: D03D49/08
Filed: 1977-10-10
Abstract: The brake mechanism is provided with an arm mounted in hinged manner relative to the loom frame. A follower element following the outer periphery of the yarn on the beam is mounted on the arm at a distance from the hinge axis. A transmission is provided between this arm and the adjustable end of the brake band. The transmission is so constructed that a rotation of the arm e.g. caused by the redn. of the outer dia. of the yarn windings on the beam, reduces the tensile force on the brake band and hence the braking action on the beam. The mechanism provides a simple and relatively cheap automatic braking system.
