Title: Recovery of vanadium from residues by cationic exchange
IPC: C22B3/00
Filed: 1971-04-14
Abstract: Method of recovering vanadium from e.g. oil, petrol residues by cationic exchange, involves (a) dissolving V with accompanying metals, e.g. Fe, Ni, under highly acidic conditions e.g. pH 1.5 (b) oxidation of solution by e.g. NaClO3 (c) precipitation of Fe and Ni by passing solution through cationic resin, e.g. Zerolit 425 (RTM).

Patent FR-2235477-A1 (FR)
Title: Image storage display tube - uses writing gun to provide selective erasure by target secondary emission
IPC: H01J31/18
Filed: 1973-06-29
Abstract: This storage tube has, within an evacuated envelope, at least one writing gun (7 and/or 8), control and deflection electrodes and a gun (6) for the maintenance of the image. The target is capable of secondary emission under the influence of the writing beam. To provide selective erasure, this tube uses the writing gun's electron beam to provoke secondary emission with a coefficient greater than unity. The target area affected by the beam is polarised to a positive potential with respect to the collector grid and therefore the secondary electrons return to the target thus neutralising the negative image charge. Suitable variation of the erase beam provides selective erasure.

Title: Human male spermic duct implant device - comprising reversible valve providing arbitrary contraception device
IPC: A61F6/24
Filed: 1973-08-24
Abstract: Valve with cylindrical sleeved inlet and outlet branches is fitted between two severed ends of the spermic duct. Ball valve with transverse central aperture, and valve stem transverse aperture, fits in valve centre section. When valve stem aperture is in line with longitudinal valve centre line, the valve is closed, and is open when this stem aperture is transverse to valve centre line. Before insertion of the cylindrical in and outlet sleeves into spermic duct, a gold fine wire mesh is wrapped around the sleeves to create a homogeneous cellular fixture between spermic duct and sleeves. For aligning purposes of the two spermic duct ends, a needle pointed at each end is temporarily inserted during implantation through the valve transverse aperture, so that each pointed end aligns each duct end section. Surgeon removes needle after implant simply by pushing the needle along part of the transverse hole in ball valve aperture, till it penetrates the duct wall tissue, after which it is withdrawn.

Title: Humidifier for skin-divers compressed air supply - draws moisture via tiny perforations from water-loaded absorbent matl.
IPC: C22B5/04
Filed: 1974-10-04
Abstract: A humidifier is claimed for the air, or other respiratory gas, which is supplied to a skin-diver, via a pressure-reducing valve from this high pressure cylinder. The humidifier, which is fitted in the line between the reducing valve and the diver's mouthpiece, comprises a container in which a water-loaded mass of absorbent material communicates with an air passage only via very small perforations, e.g. about 3-6 mm dia, such that surface tension prevents free flow through the perforations but allows them to fill with water drawn from the absorbent material as the diver inhales.
Patent FR-2251893-A1 (FR)
Title: Annealing of extruded power cable sheathing - by passing a quenched sheath through a horizontal high pressure annealing tunnel
IPC: B29C48/15
Filed: 1974-11-20
Abstract: In the continuous prodn. of power cable with concentric extruded sheathing the surface of the extrudate is promptly quenched to permit generally horizontal haul off without loss of symmetry while the sheathed cable is passed through a pressurised annealing chamber to develop optimum toughness and electrical insulation characteristics prior to being cooled to sub curing or crystallisation temps. Method is useful for mfr. of thermoplastic or rubber cable sheathing, esp. if crosslinkable by treatment with liq. peroxides and/or prodn. of sheathing >=10 mm thick, of e.g. polyethylene. The quench treatment produces an annular skin to inhibit drooling of the sheath to a pear-shaped cross-section. The sheath cools to an amorphous solid which is transparent and readily inspected for imperfections in the sheath or core to allow prompt adjustment of the initial extrusion sheathing operation. Annealing may be developed by flash heating to crosslink or fusion temps. at the sheath surface followed by controlled cooling with external pressure to produce radially transient optimum crystallisation or curing conditions in a consolidated, void free structure. Unlike vertical tower annealing treatments, cable can be produced in continuous lengths.

The armatures two separated groups of slots are separated by one or more spacing discs. The slot liners end at these discs. Despite the machines small air gap and its large amount of material it exhibits relatively little noise but has increased induction in the armature circuit.
