Title: UN SISTEMA DE TELEVISIoN EN COLORES
Filed: 1948-04-27
Abstract: Sistema de televisión en colores en el cual un solo tubo catódico, una sola trama de línea y un solo objetivo efectúan la transmisión alternativa de los componentes espectrales del lado emisor y también del lado receptor. Este sistema se caracteriza por los elementos siguientes: a) la abertura utilizable del objetivo está dividida en dos o más secciones filtrantes, de transparencias espectrales complementarias. El paso de la luz al través de estas secciones es controlado por cubas fijas puestas en serie con filtros conjugados y que actúan por turno como obturadores. Las cubas están llenas de una suspensión de pequeñas partículas planas en un líquido dieléctrico de viscosidad apropiada. Bajo la influencia de un campo eléctrico aplicado al través de la capa de suspensión, las partículas se orientan rápidamente, paralelas a las líneas de fuerza, efecto que provoca un aumento de transparencia de la cuba. Este aumento se regula a partir del estado casi opaco existente en ausencia del campo de control para llegar bajo la acción del campo excitador, a un grado de limpidez suficiente. b) La sucesión cíclica de las canales de colores sincrónica y en fase en el emisor y el receptor, es controlada por impulsos de tensión sensiblemente rectangulares, desplazados en el tiempo según la figura 3 e impuestos a los electrodos de las diferentes cubas para hacer alternar las secciones ópticas y por tanto los filtros de luz. c) Se mantiene una tensión de polarización entre los electrodos de las cubas de suspensión de tal manera que los impulsos U1 (figura 3) superpuestos a esta tensión cambien inmediatamente la transparencia de la cuba. d) La alternancia del punto 2º puede coincidir con la frecuencia de línea o con la frecuencia de imagen, la rapidez de la iluminación y del oscurecimiento de las cubas, puede, en efecto, llevarse hasta valores necesarios en el primer caso, eligiendo convenientemente las propiedades eléctricas y mecánicas del líquido de suspensión y aumentando la tensión de control. e) Los electrodos de las cubas son con preferencia capas metálicas transparentes depositadas en las paredes interiores, estas capas pueden al mismo tiempo servir como filtro óptico gracias a su absorción selectiva. f) La sección de las cubas, en el plano de la proyección, puede concebirse diferentemente: rectangular, en forma de sectores como en la figura 5, o en forma de anillos concéntricos. g) El líquido de suspensión utilizado en las cubas obturadoras, puede, bien por su coloración natural, bien por disolución de un agente colorante, servir de filtro selectivo. h) La respuesta fotoeléctrica del tubo analizador y la emisión de la pantalla fluorescente del tubo reflector son bastante homogéneas al través del espectro visible. i) Para la despolarización de la suspensión se utilizan en su caso "tops" de voltajes dosificado a que actúan en el sentido contrario del que ha provocado la polarización previa.

Patent ES-334527-A1 (ES)
Title: Electronic device for automatic indication,registration and forecast of local and distant thunderstorms
IPC: G01W1/16
Filed: 1966-12-14
Abstract: In an apparatus for indicating and recording lightning strikes a rotatably mounted tuned ferrite antenna A detects signals from the strikes in the frequency ranges 0À5-10 Kc/s. and 1-10 Mc/s. and passes them via a selective amplifier V to a rectifier GL. This produces D.C. impulses, each corresponding to a lightning strike. To determine the average intensity of the strikes the impulses are integrated by a first resistor-capacitor circuit RICI, RI1CI1, the average being taken over the period determined by the time constant of the circuit (5-60 mins.). The intensity is indicated by the meter JI in series with resistor R 1 11 across the capacitor C 1 1. To count the lightning strikes, the impulses are used to energize relay Re 1 , whose contacts r 1 change to enable the capacitor C 2 to charge from the battery B. When the relay is released, the contacts change back so that C 2 discharges to the much larger capacitor C 2 1. The voltage across this is measured by meter J 2 in series with resistor R 2 11, to represent the number of strikes. To measure the time for which the strikes occur the output from the rectifier GL is used to trigger a thyristor Th. While this is conducting, a capacitor C 3 is charged from the battery ZI. The charge acquired by C 3 is then determined by the meter J 3 , in series with resistor R 3 11 to indicate the time. The centre of the thunder-storm is located by adjusting the antenna. Instead of using the capacitive circuits referred to above for counting the strikes, the impulses from the rectifier may be supplied to heat a winding (HW) in an insulated enclosure coupled by a mercury filled capillary to a second enclosure maintained at ambient temperature. The movement of the mercury indicates the number of input pulses. Alternatively a stepping motor may be used to count the strikes (Figs. 3 and 4, not shown). The output indicators associated with the system may have special scales so marked and expanded as to warn of the increasing intensity, and thus the nearness, of the lightning strikes. The indicators may co-operate with a barograph to provide marks on the record thereof representing the lightning strikes as they occur.

Title: Methods of producing a semiconductor device and a semiconductor device produced by said method
IPC: H01L21/32
Filed: 1967-10-30
Abstract: A method of making a semiconductor device is described in which a selected surface portion of a silicon wafer is masked against oxidation, and then the surface is oxidized to grow a thermal oxide which sinks into the silicon surface at the unmasked areas, with the result that the masked silicon remains as a mesa surrounded by the sunken oxide. Then semiconductor devices can be provided by various techniques in the silicon mesa. The advantages include the provision of flat junctions, as distinguished from dish junctions in the prior art, reduced capacitance resulting from the extension of the device interconnections over the silicon wafer, and a flatter surface on top of the wafer reducing the risk of damage to the deposited interconnections.

Abstract: A marine protein concentrate is produced by contacting raw fish with a mild organic acid capable of releasing fats and oils from the fish without causing substantial deterioration of the proteins, accumulating the fats and oils released, e.g. by heating, separating the fats and oils from the treated fish to give a protein residue, extracting the protein residue with a fat solvent to remove substantially all the fats and oils, removing the solvent and drying the protein residue. The mild organic acid may be lactic or citric acid or may be produced in situ by culturing the fish with a suitable microorganism. The fat solvent may be hexane, methanol, ethanol, propanol or isopropanol.

Title: Tire-vulcanizing press
IPC: B29D30/06
Filed: 1969-05-16
Abstract: A tyre press, e.g. for the retreading of tyres, includes an upper mould part 2 movable downwardly on to a lower mould part 1, a heating bag 18 locatable, when folded double, between cylinders 12, 14 and its edges clamped to the inner one, pressure fluid cylinders 9a, 9b which act on the base of the outer cylinder to raise it to either reject a vulcanized tyre or receive a fresh tyre 46 from a support 45, Fig. 1 in the latter case frictional forces between the bag and cylinders cause the inner cylinder to be raised to a predetermined position in which it is locked before the upper mould part is lowered and the mould closed. With the cylinders 12, 14 in their uppermost positions, Fig. 2, a fresh tyre is received on a seat ring 13 of the outer cylinder, and a flange 26 of a rod 24 depending from the base of the inner cylinder engages a fixed abutment 8, and a locking bolt 28 is passed through a transverse bore in the rod to secure it. An upper seat ring 43 for the tyre is secured to a cylinder 42 and is driven downwardly relative the upper mould part by a fluid cylinder 39, and rods 48a, 48b depending from the cylinder base 41 are brought into abutment with rods 30a, 30b upstanding from the outer cylinder base so that the spacing between the rings 13, 43 is retained during the subsequent lowering of the upper mould part, the tyre, the outer cylinder and the closure of the press. The inner cylinder remains stationary during this action during which the bag impinges the ring 43 and is guided into the tyre cavity, fluid under pressure being fed into the bag via a pipe 29. On opening the press and raising the outer cylinder the heating bag is drawn into the space between the two cylinders the tyre is raised to a height enabling the support 45 to be located beneath it and the bolt 28 is removed from the rod 24 whereupon the cylinders 9a, 9b lower both cylinders 12, 14 to the position of Fig. 1.
