Patent ES-371119-A1 (ES)
Title: Foldable foam laminates
IPC: B32B27/00
Filed: 1969-09-02
Abstract: A foldable foam laminate comprises a rigid layer of foam, e.g. polyurethane foam, confined between a flexible upper skin and a foldable lower skin, the latter having at least one crimp of inverted V-shape extending from one edge to an opposite edge, the angle subtended by the "V" being 30-120 degrees, and the apex of the "V" extending at least half-way into the foam layer. The upper skin may be polyolefincoated paper and may be stripped off before folding of the laminate. The lower skin may have one or more upstanding ribs and may be metal, which is crimped by means of tools, or a flexible material such as paper, plastics or fabric which is crimped by feeding it on to a triangularly-ridged endless belt and applying the foam to make the skin conform to the belt surface. The laminate may be folded about the crimp or crimps either inwardly (i.e. to decrease the angle subtended at the apex of the crimp) or outwardly and may be folded back upon itself. A laminate having a crimp near each of its ends (Fig. 13, not shown) has its ends folded upwardly and its undersurface is glued to another laminate comprising an upper paper sheet (if desired) an inner foam layer, and a lower metal or plywood sheet, to form a roofing panel. A pair of the crimped laminates are glued back-to-back (Fig. 16, not shown) with their respective crimps running at an angle, e.g. right angles, to each other. A laminate having two spaced-apart pairs of V-shaped crimps (Fig. 12, not shown), each of c. 45 degrees and half-foam thickness is bent into a U-shape and its outer surface is provided with a further laminate comprising a paper sheet, a foam layer and an outer metal panel, to form a shop counter body. Laminates having various numbers of the V-shaped crimps are folded into various other shapes to provide roofing, wallcladding, containers and ducts. When used in roofing, a steel strip may be bolted to a singlecrimp laminate, the strip projecting beyond one edge of the laminate. The latter is then "outfolded" about the crimp through 180 degrees and the folded arm self-tapped to the projecting metal strip (Fig. 8, not shown), adhesive also being used if desired.

Title: Method for preparing a viewing-screen structure for a CRT having temperature-compensated mask-mounting means, including cooling mask during exposure
IPC: H01J9/227
Filed: 1975-11-29
Abstract: In a direct photographic process for preparing a viewing-screen structure for a shadow-mask-type CRT having temperature-compensated mask-mounting means, an inner surface of the panel is coated with a layer of light-hardenable material and then heated above 50 DEG C to dry the layer.

Title: Hydraulic system for opening and closing hopper barges
IPC: B63B35/30
Filed: 1976-05-28
Abstract: A hydraulic system for opening and closing hopper barge comprises at least one and preferably two fluid pressure cylinders which are adapted to be positioned on one of the barge parts and a piston which is slidable in the cylinder which is adapted to be connected through its piston rod to the other barge part. The cylinder is connected by a first conduit at its piston rod end and by a second conduit at the opposite end, and a pump and a return line are connected to the respective first and second conduits. A pilot valve is located in the first and second conduits and includes three separate positions. In one position a pump discharge is connected to one end of the cylinder and the other end is connected to the return, and in another position, the opposite is true. In a third position, the first conduit is connected to a check valve and the pump discharge is connected to a return line in order to short circuit the pump. One end of the cylinder, for example one having the first circuit, is provided with a check valve arrangement which permits the piston to be locked in its position in the cylinder, preventing return flow except upon the occurrence of a predetermined excess of pressure. The check valves permit relief of the pressure throughout the connective system. Before the check valve locking system is opened, the pressures lines to the associated piston are checked by an electrohydraulic pressure switch, and for this purpose a second pilot valve is connected in the first and second conduits for selectively connecting them to the pressure side of the pump or the return line.

Title: Method and plant for converting fly ash and other powdery industrial refuse into manufactured blocks suitable for discharge into the sea.
IPC: B63B35/30
Filed: 1981-04-03
Abstract: In a ship there are provided a plurality of refrigerated cells (10) in which fly ash or other powdery refuse is mixed with water the temperature being progressively lowered in the refrigerated cell until the mixture changes state from substantially liquid to solid, i.e. to ice the walls (18) of the refrigerated cell (10) are then successively heated in order to melt the ice layer which adheres thereto finally, a lower door (13) of the cell (10) is opened to cause the ice block to fall into the sea.

In order to attain this, the weight of the quantity of fly ash, present in unit volume of the mixture, must be in such a ratio that the weight of the volume of liquid displaced during the fall of the block towards the sea bed is less than the weight of the block itself.
Patent ES-8303210-A1 (ES)
Title: Position drive for railway switches.
IPC: B61L5/04
Filed: 1982-03-12
Abstract: A high-speed switch machine for actuating railroad switch points. The machine has an electric motor which drives a hydraulic pump. The pump supplies pressure fluid to a hydraulic cylinder adapted to move the switch points from an initial to a second limit position.
