Patent ES-300019-A1 (ES)
Title: An improved process for the production of crimped yarn
IPC: D02G1/00
Filed: 1964-05-19
Abstract: A process of crimping a monofilament or multifilament yarn comprises feeding an undrawn or incompletely drawn yarn - for example nylon or polypropylene - from a package to a set of crimping members or pins which with the yarn lying between them in a substantially zig-zag configuration, are moved towards and away from one another to deform and draw the yarn. As described, yarn from a package is first drawn over a heater before passing to the pins which are secured on the circumference of, and parallel to the respective axis of, one of two discs which are mounted on skewed axes so that the circumferentially spaced pins on one disc intermesh with the pins on the other disc to provide a point of maximum separation and a point of maximum intermeshing displaced 180 DEG from the first point. After the maximum lateral distortion the yarn initially relaxes a little, but thereafter due to the grip of the pins on the yarn lessening any slack in the yarn is taken up by a ringtwister or other winding apparatus. The yarn produced by this process has a high potential shrinkagee.g. higher than 8% -, a high potential crimp contraction upon exposure to heat, and, when viewed through a polarizing microscope, a uniformly interrupted fringe pattern.

Patent ES-328416-A1 (ES)
Title: High power, high frequency transistor
IPC: H01L29/00
Filed: 1966-06-27
Abstract: A transistor is made by fusing a wafer consisting of a series of alternately N+ and P + -type layers mutually isolated by insulating material to the P or N-type face of a PN wafer so that dopant from the N+ and P+ layers diffuses from the first wafer into the second to form emitter junctions and base contact layers, the material of the opposite face of the wafer serving as the collector region. The first wafer is preferably formed by oxidizing the faces of N + and P + -type silicon, germanium or gallium arsenide wafers, forming a stack of alternately P + and N + wafers, bonding them together by heating in a press, and slicing the resulting assembly perpendicular to the wafer faces. It is fused to the second wafer, formed from an N-type wafer by epitaxial deposition or diffusion techniques, by heat and pressure. Mutually perpendicular grooves 44, 46 (Fig. 7A) extending through the first wafer into the second are then formed by conventional techniques. The groove walls are oxidized and a glass block 57 softened and pressed into the grooves. Subsequently face 58 is lapped down to the grooves to isolate individual transistor elements which are then cut from the block. The N + and P + strips are finally nickel plated and tinned and copper heat sinks functioning as emitter, base and collector contacts soldered to the element, the base and emitter heat sinks, which are disposed side by side, being provided with teeth to engage all the base and emitter contact layers respectively.

Patent ES-367453-A1 (ES)
Title: Voltage regulator
IPC: H04N3/185
Filed: 1969-05-20
Abstract: In a deflection and EHT generating circuit for a TV receiver current is supplied from a voltage source B + via a variable reactance 75 to an energy storage capacitor 35 during a trace portion of each deflection cycle and a semiconductor switch 39 couples said energy storage capacitor 35 to deflection coils 33 during at least a retrace portion of each deflection cycle and includes means for varying the reactance 75 in response to variations in EHT so as to maintain image size substantially constant. As shown, horizontal deflection coil 33 is supplied with deflection current from a circuit of the type described in Specification 1,260,375 but in which thyristor 27 is connected to a tapping on the primary winding 53a of a transformer so as to compensate for the difference in voltage across diode 29 and thyristor 27 when conducting. The exchange of energy between the E.H.T. transformer 53 and the deflection circuit is so arranged that variation of beam current in the cathode-ray tube 13 will result in a variation in deflection amplitude and a change in E.H.T. voltage. If the ratio of the change of deflection current to that of the E.H.T. voltage is between one half and one, then the image width tends to remain constant despite variation in beam current. The image width is further stabilized against variation in supply voltage by comparing the voltage across capacitor 31 with that of a Zener diode 71 and amplifying the result by means of a transistor 73 which controls a saturable inductor 75 so as to vary the inductance across winding 47 and hence compensate both for change in deflection amplitude and in E.H.T. voltage. The Zener diode 71 may be connected in the emitter circuit of transistor 73 or omitted.

Title: Color phosphor electroluminescent screen with filters for color cathode-ray display tubes
IPC: H01J29/32
Filed: 1970-06-03
Abstract: A luminescent screen for a colour television tube comprising a pattern of luminescent areas, e.g. dots as shown in Fig. 1, is characterized in that the areas are separated by dark areas formed by overlapping filters. In Fig. 1 red green and blue filters are deposited on the faceplate in the pattern shown so that the areas of overlap (shown cross-hatched) do not transmit visible light, and phosphors emitting the corresponding colours are deposited over the filters so that each effective light emitting area is a curvilinear hexagon, as illustrated at 11g, which is smaller than the corresponding aperture in the shadow mask with which the screen is to be used. Processing screens.-In a photo-resist method of manufacture a photo-sensitive slurry including powdered fusible material adapted to form a green filter is deposited on the face-plate and exposed through the shadow mask to form the green filter areas. The red and blue filter areas are formed by the same process, and then the phosphor areas are also formed by the same process, preferably using a shorter exposure time so that the phosphor areas are smaller than the filter areas. The screen is aluminized and the filter components will be affixed to the substrate either in a separate heat treatment step or during bakeout. In an electrostatic process the face-plate is covered with a conductive layer and a photo-conductor, both preferably being organic so as to be eliminated in bakeout. The screen is charged by a corona discharge and exposed to ultraviolet light through the shadow mask to form a latent image which is developed by the application of a toner. The toner may include both powdered filter material and powdered phosphor material in suspension so that both are deposited simultaneously, stratification being obtained due to the different densities of the materials. Alternatively the toner may contain only the filter material after its application there will be sufficient residual charge left to allow the application of a second toner including the phosphor, or alternatively the phosphor may be sprayed over the first toner. Those combined filter and phosphor elements that overlie other filter and phosphor elements should be sufficiently thick that when the screen is in use the electrons cannot penetrate them to excite the underlying phosphor.

Title: Process for the production of stable water-in-oil emulsions of water-soluble polymers
IPC: C08F2/00
Filed: 1974-10-25
Abstract: alpha ,ss-monoolefinically unsaturated monomers which are water-soluble or are capable of forming water-soluble salts are converted into the state of a solution in the water phase of a water-in-oil emulsion. Their polymerisation is carried out in the W/O emulsion with the aid of photoinitiators which are soluble in the water phase or oil phase and with the aid of UV light. In this way, stable W/O emulsions having a high content of extremely high-molecular-weight polymers dissolved in the aqueous phase are obtainable. The preparation can be carried out either batchwise or continuously. The process is suitable for the preparation of polymers which are employed as retention agents in papermaking or as flocculants in effluent treatment.
