Title: Method and apparatus for the continuous manufacture of zigazag-shaped strutting for lattice structures and of lightwght structures comprising such struting
IPC: B21D13/04
Filed: 1963-07-03
Abstract: Corrugated strip is continuously produced by passing it between a series of relatively moving, meshing, generally triangular bending tools which form corrugations each extending across the strip, the strip being additionally shaped by the impression of a desired transverse profile thereon. Co-operating bending tools 12, 16 are carried by chain links 10 of opposed endless chains, one of which is driven, the tools being so shaped as to give the strip a trough-shaped profile as well as forming the corrugations. The nodes of the corrugations may be additionally shaped to resist buckling and this may be effected after the corrugating by a press comprising upper and lower tool carried by pairs of cranks so as to match the velocity of the strip. The tools 12, 16 may be so shaped as to form corrugations, the legs of which are laterally angled relative to one another, Figs. 8- 14 (not shown). The tools may be shaped to corrugate a plurality of strips side by side, optionally with corrugations of different height and/or bend angle, Figs. 15 and 17 (not shown). To aid the tools 12, 16 to disengage the corrugated strip they may be moved apart at the exit by cam means, Figs. 18-19 (not shown). The tools may incorporate a cam-actuated punch at their apices to deform the strip. The corrugated strip is connected to upper and lower chord members by welding to form pylons, masts, joists or the like.

Patent ES-338911-A1 (ES)
Title: Manufacture of prestressed concrete pipes
IPC: B28B21/90
Filed: 1967-04-04
Abstract: Prestressed reinforced concrete pipes are formed by forming a concrete pipe containing reinforcement in a hollow resilient mould, applying pressure inside the pipe before the concrete hardens and then releasing the pressure and removing the pipe from the mould. As described the mould comprises a rigid casing 2 and a resilient moulding surface 1 preferably of reinforced glass fibre. End pieces 7, 6 contain holes 10 in which the reinforcement 8A is located the concrete pipe 8B being formed round the reinforcement by any suitable process such as rotational casting. A lining 11 impermeable to water is placed over the inner face of the concrete and a bulkhead assembly 12 comprising a tube 14 with ends 16 and 18 is inserted into the mould so that end 16 sealably abuts end 7. A further bulkhead 22 with attached rim 24 seals the other end of the water cavity (13) and is attached to end member 18 by bolt 19 and nut 27. Suitable sealing rings are supplied at each join to prevent leakage of water. Warm water (to speed the setting of the concrete) is supplied under pressure through pipe 30 and the pressure maintained until the concrete has set. The water pressure is released and the bulkhead assembly 12 and also rings 7 and 6 are removed. Steel discs 31, 32 fitted with rubber gaskets are then fitted, 31 to the right hand end of the pipe and 32 (which contains a water inlet) to the right hand end of rigid casing 2. Water pumped through disc 32 into the space between these discs forces the pipe out of the mould.
Patent ES-342345-A1 (ES)
Title: Method of Fibrillating Synthetic Thermoplastic Film and apparatus therefor
IPC: D01D5/42
Filed: 1967-07-26
Abstract: A web of film or a filament consisting of an organic synthetic thermoplastic polymeric material and which has been stretched in the longitudinal direction at a stretch ratio sufficiently high to render it fibrillatable is fibrillated by passing it between a pair of co-operating rotating parallel nip rollers which exert a pressure on the film or filament as it passes between them, the direction of travel of the film or filament being parallel to its length, and one of the rollers oscillating along its longitudinal axis or oscillating both rollers along their longitudinal axes in opposite directions. The film may be gathered into a rounded or folded configuration before being passed between the rollers. The frequency of oscillation may be 1000 to 4000 oscillations per minute and the amplitude of oscillation may be 0À1 inch to 6 inches. The rollers may exert a pressure on the film or filament of at least 10 lb. per sq. inch of cross-sectional area of the film or filament. The film or filament may be given two or more passages between the same or different pairs of rollers. The film or filament may be fed between the roller at the rate of 100 to 1000 feet per minute. After passage between the rollers the film or filament may be allowed to relax in an untensioned condition for a period of time sufficient to allow the fibrillated film or filament to crimp spontaneously. The film or filament may consist of a 1-olefin polymer containing polymerised units from one or more C 2 -C 8 monoolefins such as polyethylene or polypropylene. Alternatively, it may consist of a polyamide, a polyester, polyvinyl chloride, polyvinyl alcohol, polyvinyl acetate, polyvinylidene chloride or an acrylic polymer.
Patent ES-344339-A1 (ES)
Title: Spring Brake Systems.
IPC: B60T15/08
Filed: 1967-08-22
Abstract: In a spring-applied pneumatically-released braking system the manual control valve is in the form of a housing comprising separate upper and lower parts 2, 3 respectively, separated by spacer 4 and surmounted by a rotatable cap 5 carrying an operating handle 6. Rotation of handle 6 causes longitudinal movement of a member 8 by the action of cam surfaces (not shown) formed on members 8, 9 member 8 carries a stop collar 10 in contact with which is spring 11. A slidable piston member 12 is kept in contact with the other end of spring 11 by means of a further spring 23 an extension 14 of piston member 12 carries a valve seat 15 which in conjunction with closure member 16 forms an exhaust port. A further fixed valve seat 17, forming with closure member 18 an inlet valve, is connected to compressed air inlet port 20. Inlet valve 17/18 is biased to the closed position by spring 21 urging a retaining ring 22 against closure member 16. Over the major part of the rotation of handle 6 the arrangement acts as a self-lapping valve giving a steadily increasing pressure in chamber 24 connected to the brake cylinder: toward the end of the downward travel of member 8, however, stop collar 10 comes into engagement with extension 14 of piston member 12. Thereafter piston member 12 is forced rapidly downwards closing valve 15, 16 and opening valve 17, 18 to bring the pressure in chamber 24 up to the maximum supplied pressure: the operating point at which this occurs may be chosen by selection of the thickness of spacer 4. The arrangement is described as applied to a braking system in which the brake cylinder is double ended, the one end providing for "emergency" operation under spring control, with release via a control valve of the type described. The other end provides for normal "service" operation under pneumatic control via a separate control valve, each control valve being provided with its own reservoir (Fig. 1, not shown).
Patent ES-346822-A1 (ES)
Title: Colour Display Cathode Ray Tube Display Screens.
IPC: H01J9/227
Filed: 1967-11-06
Abstract: A multi-colour cathode-ray tube is manufactured by passing light from a source through a perforated shadow mask to fix luminescent material of each colour, a photo-cell responsive to light from the source controlling the energy supplied to the source to maintain light intensity constant. The screen of the tube is moved from one to the other of a number of operating stations. At each station a layer of luminescent material of a different colour is applied together with a photo-sensitive lacquer which fixes the material to form dots where it is exposed to light from a discharge lamp passing through a suitably perforated shadow mask which may be that finally used in the tube. The unfixed material is then washed off before passing the screen to the next station at which a further pattern of dots, displaced from the first and corresponding to a different colour, is produced. In Fig. 2, the voltage output of a photo-cell 12 responsive to light from a HPMV discharge lamp 7 at a typical station is compared with a reference voltage from a potentiometer 31 so that any difference is effective through a transistor amplifier 29 to operate a motor 30 adjusting the tapping 24 of a lamp supply transformer 23 in the appropriate direction to maintain constant light output from lamp 7. The lamp is switched on by a self-holding manually-operated push button switch 44 which remains on until a clock 43 releases a pin 40 after a time suited to the colour. When the reading of a voltmeter 45 exceeds a predetermined value, lamp 7 needs replacing. Operation of the lamp above its rating because of its intermittent use is referred to.

Patent ES-352864-A1 (ES)
Title: Angular speed change sensor
IPC: B60T8/74
Filed: 1968-04-18
Abstract: An inertia switch which closes when a preset rate of change of speed of a rotatable member such as a vehicle wheel is exceeded, comprises a flywheel 29, Fig. 3, rotatably supported in a housing 25, 31 attached to the rotatable member, the flywheel being frictionally coupled to an actuator plate 38 which is coupled for limited rotational movement relative to the housing against a biasing spring 53, displacement of the plate completing an electric circuit through an electrical contact finger 42. The actuator plate 38 is rotatably mounted on a central boss 32 and its movement is limited by a housing stud 33 extending through an arcuate slot 48, Fig. 4, in the plate, the plate being biased to a rest position at one end of the slot by spring 53. Frictional coupling of the actuator plate to the flywheel is effected by a centrally pivoted spring steel plate 58 having leaf springs 59, 61-63 which frictionally engage a flywheel recess 64. Normally the electrical contact finger 42 rests on an insulating stud 57, but when the actuator plate is displaced against the spring 53 due to the preset rate of change of speed being exceeded, the finger engages the conductive body of the plate and completes an electrical circuit from a rivet 47 to a brake pressure regulating apparatus 22 through a slip ring and brush 16, 17. The switch may be mounted either centrally, Fig. 2 (not shown), or eccentrically, Fig. 1, of a vehicle wheel, and in either position the flywheel tends to rotate relative to the housing when the vehicle decelerates.
Patent ES-357854-A1 (ES)
Title: Process and apparatus for treating textile materials
IPC: D06M13/535
Filed: 1968-09-05
Abstract: In a process for treating textile material the material is initially vacuum degassed at a pressure between zero and 10 inches of mercury absolute, and then immediately treated with a fluid treating agent on leaving the vacuum degassing zone, for dyeing, scouring, resin treating or mercerising, whereby the penetration and pick-up of the treating agent by the material is increased, the entrance and exit of the evacuating zone being sealed to maintain evacuation and prevent entry of the treating fluid into the zone. In one embodiment a continuous length of material 10 is passed vertically through an evacuated chamber 4 having entry and exit sealing rolls 12, 14. The material is preferably exposed to a vacuum of 0.6 to 3.5 inch mercury absolute for from 1 to 15 seconds. On being withdrawn from the vacuum chamber 4 the material is immediately passed through the treating liquid 20 located in the nip of the upper sealing rolls 14, and thence between padder rolls 22. The pressure between the sealing rolls 12 or 14 is adjustable by moving one roll relative to the other. In alternative embodiments the treating liquid is located in a separate chamber immediately adjacent the exit from the vacuum chamber and the seals of the vacuum chamber may be cooperating rubber flaps or inflated non- rotating tubular members. To further improve the penetration and pick-up of the material it may be heated during its passage through vacuum chamber to from 50 to 150 C such as by infra-red or dielectric heaters or by passage over heated rollers. Also the material may be passed through the vacuum chamber zig-zag fashion over rollers, and the vacuum chamber may be horizontally arranged or may be spherical. In yet a further embodiment the vacuum treatment is carried out at 0 C. In an alternative embodiment the continuous length of material is first passed through an additional treating agent 50, then vacuum chamber 4 (Fig. 10) in a zig-zag manner during which it is heated by heaters 55, and is then passed through the main treating chamber 59. The treating agent may be a liquid or a gas. Several specific examples are given.

Title: Arrangement for preventing the escape of dust and gas during the filling of a furnace
IPC: C10B31/04
Filed: 1974-07-17
Abstract: A furnace has a normally closed filling inlet. There is provided an arrangement for opening the filling inlet, then filling the interior of the furnace with a charge, and then reclosing the inlet, all in gas-tight and dust-tight manner, in order to prevent the free escape of dust and gases into the ambient atmosphere during the filling of the furnace. The arrangement includes a housing having an opening positioned in proximity to the normally closed filling inlet. A sealing arrangement is activatable for establishing a gas-tight and dust-tight seal between the portion of the housing surrounding the housing opening and the portion of the furnace surrounding the normally closed filling inlet, so as to confine within the interior of the housing any dust and gas entering the filling inlet or escaping from the filling inlet during the filling of the interior of the furnace. Inside the housing there is provided an arrangement activatable for opening and closing the normally closed filling inlet of the furnace. A filling arrangement is operative for conveying a charge through the interior of the housing and into the furnace filling inlet. The filling arrangement has a discharge end portion located within the housing gas-tightly and dust-tightly connected to the housing so that dust and gas leaving the discharge end portion but not entering the filling inlet is confined within the housing and is unable to freely escape into the ambient atmosphere. Advantageously, the arrangement is used in conjunction with a battery of furnaces having respective filling inlets arranged in a row, and the arrangement, as a whole, is movable into sealing engagement with successive ones of the filling inlets for filling successive ones of the furnaces.
