Patent ES-272301-A1 (ES)
Title: Method of manufacturing decorated molded articles from finely divided thermoplastic materials
IPC: B29C67/00
Filed: 1961-11-24
Abstract: In a powder sintering method the articles are decorated by a thermoplastic film. The film may be stuck to the wall of the p mould by an adhesive or may be formed from coloured powder which is also stuck to the wall by an adhesive. The mould walls may be painted with a decoration. Another method is to produce an uncoloured plastic film adjacent to the walls either by using a preform or by beating thermoplastic powder, and strewing coloured powder on the film whilst it is still stickly to form the decoration. The adhesive may be silicon oils and fats, or a pasty mixture of solid and liquid hydrocarbons. The Specification describes several examples.

Title: Method and apparatus for controlling and metering the flow of granular material
IPC: E01C23/20
Filed: 1967-08-04
Abstract: In a road line marking vehicle wherein paint-spraying nozzles 37-38-39 are followed by glass bead spraying nozzles 34-35-36, a smooth adjustable flow of beads from a pressurised tank 11 is obtained by connecting the nozzles 34-35-36 to a manifold or container 30 which is maintained at a desired pressure by an air line 16-24-26 controlled by a valve 21. The .pressure in container 30 tends thus to remote the effect of fluctuations in the pressure drop in the bead line 28 (e.g. due to variations in bead packing). As shown the air line is supplied from the compressor 13 which pressurises tank 11, and is connected through filters 27 to two containers 30, 30'. The valve 21 may be controlled manually, or electronically in relation to vehicle speed.
Patent ES-344542-A1 (ES)
Title: Apparatus for continuously casting metals
IPC: B22D11/128
Filed: 1967-08-19
Abstract: An increased rate of intermittent withdrawal of a continuously cast strand 6 (from at least one mould 2 connected to a furnace 1 and surrounded by a cooler 3) by pairs of gripping rollers 8, 9, is said to be achieved, by employing an hydraulic motor 15 (having an intermittently operated valve 19 in its pressure-medium feed circuit 12, 14) to rotate at least one roller. Metal of fine structure is said to be thus produced. The valve 19 may be a magnetic valve operated by a pulse generator but as shown it is a valve operated by a cam 21 driven through a variable speed gear to vary the length of the cycle. A regulator 20 controls the quantity of medium fed to the motor 15. As shown the upper rollers 8 are releasably pressed against the strand 6 and the lower rollers 9 are all driven via a gear 13, a shaft 11 and an endless chain 10. Both sets of rollers may be pressed against the strand and one or several lower rollers 9 may be driven, each by its own hydraulic motor. One or more of the upper rollers 8 also may be drivable.
Patent ES-346794-A1 (ES)
Title: Process for welding two pieces of plastic by friction of one against the other and apparatus for carrying out this process
IPC: B29C65/00
Filed: 1967-11-04
Abstract: Two sheets of plastics material, e.g. polypropylene, are friction welded together by vibrating one of the sheets in a direction parallel to the other whilst holding the two sheets together under pressure, the duration of the welding operation being automatically timed, e.g. by means for stopping the vibration of the one sheet upon increase of sliding resistance between the sheets when the interface of the sheets melts. As shown, an eccentric 6 carried at the end of the shaft of an electric motor (2), Fig. 2 (not shown), turns in a square 7 sliding in a rectangular opening 8 in a welding tool 9 the lower end 92 of which is serrated to grip the upper sheet of a pair to be welded which are positioned on a plate 13 of a base 12. The tool 9 is spring-urged upwardly against a tempered steel ball 25 or cylinder which rests in a hollow 93 in the upper part 91 of the tool 9 and is received in a recess in a piston 16. The tool 9 is lowerable by a lever 14 having an eccentric portion 15 which acts on the piston 16 through a strong helical spring 17. A second lever 18 acts resiliently on a toothed drum 19 co-operating with a plate 20 for advancing the sheets. The working surface of the tool 9 comprises toothed zones 31, Fig. 3, and channels 32 between the zones 31 into which channels plastics material can flow during welding. In a modification (not shown), the perimeter of the working surface of the tool 9 is raised to provide a boss. In operation, the motor (2), Fig. 2 (not shown), is automatically operated through a pusher (22) and switches (23) when the lever 14 is lowered. Initially, the rubbing of the ball 25 against the piston 16 and the tool 9 is such that the part 91 does not move laterally relative to the piston 16. When the resistance of the upper sheet increases due to its adherence to the lower sheet the tool 9 is braked and the part 91 begins to oscillate about the fixed lower part 92 and thus avoids tearing of the upper sheet.

Title: Improvements in or relating to Tubular Scaffolding
IPC: F16B12/40
Filed: 1968-06-01
Abstract: A scaffolding coupling for connecting together in aligned relationship two scaffold tubes of cylindrical form in cross-section, is of the kind comprising a pair of mutually parallel clamping elements 11, each of elongated form and of part-circular configuration peripherally, the opposite ends of each of which elements are adapted to extend within the two scaffold tubes, connecting means, e.g. a pin 12, connecting said two clamping elements together in such a manner as to permit of the elements moving relatively into and out of clamping engagement with the interior of the two tubes, and clamping means for forcing the two clamping elements relatively apart into frictional clamping engagement with the interior of the two tubes to be connected the connecting means are so formed as to permit of the two clamping elements moving angularly relative to one another about an axis parallel to their length, and the clamping means comprise an impact drivable member 14 of wedge shape extending between the two clamping elements in a direction transversely of their length, and having relatively inclined clamping element engaging faces 14a, the arrangement being such that when the wedge member is driven in said transverse direction, in addition to the two clamping elements being displaced relatively apart from one another, the two clamping elements are permitted by the connecting means to rock relative to one another about said axis, parallel to the length of said elements. As shown, the elements 11 are of part-circular configuration and the pin 12 extends through the tube 10 to secure the elements non-detachably to the tube. The wedge member 14 extends through openings 15, 16 in the wall of the tube and disposed at different levels so that the member is inclined downwardly. In a modification, the member 14 is of T-section and passes through diametrically opposed T-shaped slots to engage elements 11 which are D-shaped in crosssection.

Patent ES-373717-A1 (ES)
Title: Process for preparing supported permanently-magnetizable metals or alloys
IPC: B22F9/24
Filed: 1969-11-20
Abstract: Supported permanently magnetizable metal (s) or alloy(s) are produced by suspending a finelydivided carrier material in a solution containing the metal ions and gradually generating OH1 ions homogeneously in the solution at a sufficient rate to deposit the active element(s) on the carrier but not fast enough to get nucleation of the pure precipitate in the solution, the precipitate being hydroxide or hydrated oxide, removing the carrier from the solution and then reducing the precipitate to give metal or alloy particles of size in the single-domain range. The reduction may be by means of hydrogen, optionally in the presence of water vapour, or by hydrazine and the precipitate may be calcined in air before reduction. The loaded carrier materials may be impregnated under vacuum with a polymerizable monomer or molten polymer for application to tapes or for the production of sheets or moulded bodies to form magnetic recording material. The examples refer to the deposition of Fe or Ni- Co alloy on SiO 2 particles.

A single diffusion from POCl 3 defines the n+ type region 32, the two junction depths being determined by the different dopant concentrations in the first region 28/30. Alloyed Al electrodes 38, 40 are finally applied as shown.
