Patent ES-334694-A1 (ES)
Title: Method and apparatus for producing conductors surrounded by three or more extruded layers
IPC: B29C48/06
Filed: 1966-12-20
Abstract: An electrical conductor core 10 is given a relatively thin conducting covering 14 at an extruder (12), Figs. 1 and 2 (not shown), and is then passed through a second extruder 16 to receive a relatively thick insulating covering 18 and simultaneously a further relatively thin conducting covering 20. The covering materials may be curable butyl rubber or ethylene-propylene polymers, but are preferably of cross-linkable polyethylene, the conducting layers being suitably loaded with carbon black. Extruder (12) has an exchangeable die (35) centred by screws (42). Extruder 16 is spaced downstream of extruder (12) to allow sufficient cooling of covering 14 before it passes through die 55. Covering 20 is derived from material 79 which is forced through conduit 76 to a peripheral channel 82, which promotes even flow, and is then bled to the interface between die 55 and insulating material 69 which forms covering 18. This form of feed gives to material 79 the action of a lubricant and it is stated that this material may be a compound, e.g. of polyethylene and butyl rubber. A curing chamber (22), Fig. 1 (not shown), preferably a catenary chamber, is provided downstream of extruder 16 and a further extruder (24) may provide a protective covering (23), Fig. 6 (not shown), applied before or after passage through chamber (22). All the extruders may incorporate screw impellers. Preferred thicknesses of the coverings are 15-20 mils for covering 14, 150-350 mils for covering 18 and 15-30 mils for covering 20.
Patent ES-336819-A1 (ES)
Title: Laminated glass structures
IPC: B32B17/10
Filed: 1967-02-14
Abstract: Glass laminates comprise at least one layer of glass adhered to a layer of a novel ethylene copolymer (see Division C3) which comprises at least 35% by weight of ethylene units, units of one or more hydroxy or epoxy aliphatic or cycloaliphatic monoesters of acrylic or methacrylic acid, in which the (cyclo)aliphatic radical consists only of C, H and O and contains not more than 6 carbon atoms, and 0-55% by weight of units of a further comonomer having one ethylenic double bond which is an ester of acrylic or methacrylic acid (e.g. an alkyl ester) or a vinyl ester (e.g. vinyl acetate). The hydroxy or epoxy ester may be a hydroxyalkyl or glycidyl acrylate or methacrylate. Generally, the copolymer layer is present as an interlayer between sheets of glass or between a sheet of glass and a transparent or translucent, substantially rigid plastics material, e.g. polymethyl methacrylate, rigid polyvinyl chloride, polystyrene or a polycarbonate. Such a laminate can be prepared by sandwiching the copolymer layer between two sheets of glass or between a sheet of glass and a sheet of the plastics material, and heating the assembly to a temperature above the melting point of the copolymer (e.g. 110-130 C.) for a sufficient time and at a sufficient pressure to effect bonding the copolymer layer may be ridged or roughened to prevent blocking. In one particular embodiment, the assembly is placed in a flexible plastics or rubber bag which is then evacuated, and the bag and the assembly are heated in an oven or, preferably, in an autoclave at elevated pressure the assembly is then cooled before being removed from the bag. The glass surfaces to be bonded may, if desired, be pre-treated with an adhesion promoter, e.g. silanes of the type described in Specification 1,095,700. In examples, the copolymer is admixed with 4,41- thiobis - (3 - methyl) - 6 - t. - butylphenol), as antioxidant, before being formed into a film layer. The glass laminates are useful as safety glass in such applications as vehicle windscreens, bandit- or bullet-resistant windows or display cases, doors and wall panels in buildings, and transparent or translucent light fittings.
Patent ES-342698-A1 (ES)
Title: Armor piercing,sabot shells
IPC: F42B14/06
Filed: 1967-07-06
Abstract: An armour piercing projectile for firing from rifled gun barrels comprises a hard, dense, metallic core 1, e.g. of tungsten carbide, housed within a detachable, tubular case 2 of lighter material e.g. aluminium alloy or plastics, the core being locked in the case at the front end by a split ring 6 which protrudes from an annular groove 7 to abut a shoulder 5 on the core. When the projectile is fired, the case 2 and core 1 are set spinning and the ring 6 expands wholly into groove 7. Due to resistance in moving through the atmosphere the case 2 then quickly drops away from the core 1. A hole 12 in the base of the case prevents the occurrence of suction which would oppose the separation and also enables a tracer compound 13 to be ignited by the hot gases in the gun barrel: An empty annular space (not shown), may be provided inside the case so that it contacts the core over two separate areas of its length. The case may also be fitted on the outside with a thin steel ring (not shown) to prevent too deep a penetration of the barrel riflings into the case.

Patent ES-355348-A1 (ES)
Title: Irrigation conduit and method for producing such
IPC: B29C65/56
Filed: 1968-06-22
Abstract: An irrigation, or soaking, conduit 5 has a wall structure of intercommunicative cellular plastics material, e.g. formed ethylene polymers and copolymers, and an outer surface which, at normal operative pressures, is impervious to water, the wall having at least one score line 9 which penetrates the outer surface and destroys its water impervious nature. As shown, the conduit has four longitudinal score lines 9. Alternatively, a single helical score line, or a number of axially-spaced, ring-shaped, score lines, may be provided. The conduit is formed by extruding a hot hollow conduit from a foamable thermoplastic resin, e.g. polyethylene, with an alkali metal bicarbonate gas-releasing agent and a small amount of naphthylenic-type pail oil, the extruding taking place at about 300- 360 F. Air is then forced through the extruded conduit to expand it as it passes through the extrusion die and into a cooled sizer which cools, sizes, and hardens the conduit to form a water impervious external wall surface. The air injection also aids in connecting the cells of the foamed plastics. Each score line is then made in the external wall surface.

Title: Process for the purification of titanium tetrachloride
IPC: C01G23/02
Filed: 1969-05-09
Abstract: Vanadium compounds (e.g. VOCl 3 , VCl 4 ) which exist as impurities in titanium tetrachloride are removed therefrom by treating with hydrogen sulphide at from 130-180 C., the amount of hydrogen sulphide used being from 1 to 3 mols. per mol. of vanadium compound present, whilst at the same time cooling the crude titanium tetrachloride by injection of liquid titanium tetrachloride. The process may be carried out in a spray-quencher, and the contact time (for the reaction) should be at least 10 seconds, preferably 15-50 seconds. Afterwards the vapours may be scrubbed with liquid titanium tetrachloride, this liquid being recycled to the hydrogen sulphide treatment and the gaseous purified titanium tetrachloride sent for rectification. The gases may be passed through a cyclone between the spray-quencher and scrubbing apparatus to remove some of the solid particles, some of which collect in the sprayquencher. The process may be used to treat impure titanium tetrachloride made by chlorinating titaniferous material. Molten elementary sulphur formed in the reaction between hydrogen sulphide and the vanadium compounds is discharged with solid impurities from the spray-quencher and cyclone. In Example 1, the solids contained 4.9% sulphur and in Example 2, where a larger ratio of H 2 5 was used per mol. of vanadium compounds the solids contained about 25% by weight of sulphur.
