Title: Continuous casting plant for slabs
IPC: B22D11/14
Filed: 1972-04-12
Abstract: The invention relates to a continuous casting plant wherein a cooling means is provided which includes, apart from customary nozzles, flat ray nozzles which are arranged at a distance of the slab guided in a supporting and guiding structure between rollers so as to be parallel to the width of said slab, the longitudinal axes of said flat ray nozzles extending parallel to the axes of the rollers. By means of these flat ray nozzles it becomes possible to spray the underside of the bar and the rollers in a uniform and plane manner. A satisfactory cooling is acheived also when the bar owing to skrinkage lifts off the rollers.

Title: High pressure spray washing system
IPC: B05B12/10
Filed: 1974-05-16

Patent ES-435736-A1 (ES)
Title: Method of reshaping resiliently deformable sheet material for integration with a flexible plastic foam as a cover therefor
IPC: B29C51/40
Filed: 1975-03-18
Abstract: A method is disclosed of reshaping a sheet of resiliently deformable material impervious to fluid by conforming it to the cavity of a female mold and casting a flexible plastic foam into contact with said sheet material, whereby said material is integrated with the foam and forms a cover sheet therefor. A perforated elastic diaphragm is interposed, during the reshaping and foam casting process, between the cover sheet and surface of the mold cavity so that the cover sheet is in superimposed direct contact with the diaphragm throughout its area. The two are clamped to the periphery of the mold to form a seal thereat, and a differential pressure is applied across the cover sheet and diaphragm. The sheet is therefore deformed against the walls of the mold simultaneously with the diaphragm and is stretched evenly with the diaphragm in order to produce uniform thickness. If the cavity of the mold has a complicated configuration a diaphragm of varying thickness is used in order to ensure uniform stretching of the sheet. In simple molds, the diaphragm can be made to slide against the walls of the mold by using a lubricant which does not come in contact with the sheet being molded. The sheet and diaphragm together stretch uniformly because the diaphragm can slide against the walls of the cavity.

Title: Production of pure alkali metal phosphate solutions from wet-processed phosphoric acid
IPC: C01B25/30
Filed: 1975-11-11
Abstract: Production of pure alkali metal phosphate solutions by neutralizing wet-processed phosphoric acid with an alkali liquor and/or carbonate. To this end, the wet-processed phosphoric acid is neutralized to a pH from 4 to 9, the resulting neutralization sludge consisting substantially of insoluble aluminum and iron phosphates is separated from the alkali metal phosphate solution and scrubbed with water, the sludge so treated is mixed with alkali liquor, alkali metal phosphate solution and water-glass so as to establish in the resulting suspension a molar ratio of SiO2 to Al2O3 of at least 2 : 1 and a molar ratio of dissolved alkali metal oxide to dissolved P2O5 ranging from 2.9 : 1 to 3.3 : 1, the whole is heated to temperatures from 80 DEG to 100 DEG C to effect breakup of the sludge in the suspension with the resultant formation of a solid matter residue together with a trialkali metal phosphate solution, the solid matter residue is separated from the trialkali metal phosphate solution, water-scrubbed, and discarded. More particularly, crude wet-processed phosphoric acid containing more than 45 weight % of P2O5 is diluted with a portion of the scrubbing water obtained during operation and its P2O5-content is thereby reduced down to 30 to 45 weight %. The acid so treated is neutralized with an alkali liquor and/or carbonate and with the trialkali metal phosphate solution originating from the processed neutralization sludge.

Title: Method to apply a protective layer to the surface of optical reflectors, and so-made reflectors, particularly automotive vehicle head lamps
IPC: F21V7/22
Filed: 1976-08-20
Abstract: The reflectors, for example for automotive vehicle head lamps are reflectorized by evaporating aluminum thereon in a vacuum vessel at a vacuum of about 10-7 bar thereafter, and without removing the reflectors, a gaseous monomer is introduced raising the pressure to about 5 x 10-6 bar to deposit a protective layer by polymerization from the gaseous phase. The monomer gases, preferably, are low molecular weight siloxanes having methyl-, vinyl- or phenyl groups, preferably hexamethyldisiloxane (HMDS), or methyl-, vinyl- or alkoxy silanes, preferably vinyltrimethylsilane (VTMS), polymerization being accelerated and ensured by an electrical discharge generated within the vessel by a heated electron emitter placed at a negative voltage with respect to the reflector blanks. After polymerization, the layer is rendered hydrophilic by treatment with oxygen at a pressure of about 10-2 to 10-3m bar to form an organosilicon polymeric protective layer which is inherently hydrophobic and has a hydrophilic surface.

Title: Manufacturing method for a high pressure distributor rotor
IPC: B21K1/20
Filed: 1978-01-05
Abstract: A method for manufacturing a rotor, in particular for a power steering rotary valve, wherein a rotor is positioned in which a plurality of axial grooves have previously been designed.

Title: Device for computer tomography
IPC: A61B6/00
Filed: 1978-09-12
Abstract: A device for computer tomography, comprising an X-ray source, a number of X-ray detectors and a signal processing network which includes a comparator for comparing detector output signals with data obtained during measurement of a calibration material and stored in a memory.

Patent ES-476337-A1 (ES)
Title: Arrangement for controlling a fluid under pressure by means of a seal
IPC: F16K11/07
Filed: 1978-12-26
Abstract: A hydraulic valve is disclosed which has a gasket sealing against and, to a limited extent axially movable on, a movable valve member. The valve member has a radial shoulder sealing surface which is spaced from a matching, larger diameter concentric radial shoulder sealing surface of the body of the valve. The sealing surfaces can be aligned with each other by an axial movement of the valve element, with a radial spacing between them providing a fluid passageway. The gasket has an angular cross-section, with the apex being toward where the sealing surface of the valve element adjoins the valve element surface over which the gasket extends outward from the axis of the valve element. The angular relationship between the aligned sealing surfaces and the sealing portion of the gasket is such that when the gasket is moved toward the sealing surface of the body by the valve element, the outer lip of the gasket sealing portion first contacts the surface, thus significantly blocking fluid flow. This causes the gasket sealing portion to be pushed by the fluid pressure itself so that the gasket rotates about its cross-sectional torsional axis to press the sealing portion flat against the aligned sealing surfaces and over the fluid passageway to block its flow. Various relative configurations of the gasket and sealing surfaces are disclosed. Also disclosed are combinations of such arrangements for forming multiple-function valves.

Patent ES-480541-A1 (ES)
Title: Method of modulating a composite color television signal on a carrier signal and device for carrying out said method
IPC: H04N11/00
Filed: 1979-05-14
Abstract: A method of modulating a composite color television signal on a carrier wave. The luminance signal is frequency-modulated on the carrier wave. The chrominance signal is translated to a subcarrier wave frequency either by mixing the modulated carrier wave or frequency modulating the carrier wave with said chrominance signal. Subsequently, the carrier wave is pulse-width modulated with said subcarrier wave. In this way a signal is obtained from which the original color television signal can be recovered by a single frequency demodulation operation, while the normally occurring undesired interference components can be reduced substantially.
