Patent ES-429345-A1 (ES)
Title: Crosstalk suppressor for magnetic deflection yokes
IPC: H04N3/16
Filed: 1974-08-17
Abstract: Ringing in both the horizontal and vertical sections of a magnetic deflection yoke in a cathode ray tube system is eliminated by inserting a toroidal transformer in the low frequency axis deflection circuit. The flow of the common mode current is through one winding of the transformer, thence through the low frequency axis yoke winding and out of the transformer in the opposite direction through a second winding. The two windings through which the common mode current flows are balanced and series opposing and therefore no common mode signal is transferred to the third winding of the transformer. However, when an extraneous or unwanted signal is generated by the high frequency retrace signal through capacitance coupling between the horizontal and vertical windings, this unwanted signal is transferred from the two windings through which the common mode current flows to the third winding in the transformer. Thus, the two windings act as a primary to the third winding. Connected across the third winding is a variable resistor which can be adjusted to critically damp the ringing of the magnetic deflection circuits.

Patent ES-442314-A1 (ES)
Title: Grid lattice with horizontally-movable bar
IPC: G21C3/334
Filed: 1975-11-04
Abstract: A typical embodiment of the invention provides a means for selectively inserting and withdrawing one or more fuel rods from a fuel element cellular grid structure. The transverse stubs on one side of a long, thin bar are turned through 90 DEG to extend across the gap between mutually perpendicular grid structure plates. The extreme ends of these stubs engage the adjacent portions of the associated plates that form part of the grid cells. Pressing the stubs against the plate portions through the application of appropriate force in a longitudinal direction relative to the bar deflects the engaged plates through a sufficient distance to enable fuel rods to be inserted into, or withdrawn from, respective cells. After rod insertion, the force applied to the bar is released to enable the plates to relax and engage the fuel rods. The bars are rotated once more through 90 DEG and withdrawn from the grid structure. A similar procedure is employed to withdraw fuel rods from the grid structure.

Patent ES-452039-A1 (ES)
Title: Incorporating a gas in candy
IPC: A23G3/34
Filed: 1976-10-01
Abstract: This invention relates to a method of incorporating a gas in a candy glass. The incorporation or mixing of the gas takes place in a vessel containing hot candy (sugar) melt under superatmospheric pressure. The melt is stirred within the vessel using a rotatably mounted shaft with paddle blades attached to it and is mounted on the vertical axis of the vessel. Said shaft has a hollow interior with sidewall openings at each end. The level of the melt in the vessel envelops the paddle blades and the lower opening of said shaft. Thus, when the gas is introduced at the top of the vessel, it enters the shaft at the top opening and exits at the bottom opening and is dispersed within the melt by the rotating paddle blades.
Patent ES-460639-A1 (ES)
Title: Methods of and apparatus for encoding and recovering binary digital signals
IPC: H04L25/49
Filed: 1977-07-11
Abstract: In this method, which can be used, in particular, in transmission systems and in magnetic storage and recovery systems for digital data, for example three bits in each case (three time intervals T) of a binary data signal are combined to form one word. This word corresponds to data cells of the transmission or recording signal. A data cell (Z) exhibits six possible points of signal change (P1 to P6). The binary data signal is converted into a transmission or recording signal in such a manner that a minimum distance (3/2 T) and a maximum distance (6 T) is always ensured so that self-clocking is possible during the reading. Since it is not sufficient only to pay attention to the signal changes within one data cell (Z) but care must also be taken that two signal changes (P5 and P1) of adjacent data cells (e.g. Z4 and Z5) are not closer together than the required minimum distance (3/2 T), the present word is in each case compared with the preceding and following word. If it is found for a word, that a signal change should take place at a point (P5) which is not the minimum distance (3/2 T) away from the point at which a signal change (P1) for another word should take place, the two signal changes are combined at one point (P6). For this purpose, the device for carrying out the method has a coding device with three coders (17, 24, 29) for the present, preceding and following word and switching means (33) which provide a signal change at the boundary (P6) between the data cells (Z4, Z5) instead of the two prevented signal changes (P1, P5).

Filed: 1977-08-20
Abstract: Apparatus is provided for supporting and drivingly opening and closing an overhead single-panel door such as a garage door. The apparatus includes drive rollers protruding from the plane of the door at respective opposite upper corners thereof, which drive rollers are bearingly supported by a plate member attached to the door. These drive rollers are supported from underneath and in driving contact with fixed guide tracks arranged at the building accommodating the door. In order to insure continuous firm driving engagement of the drive rollers with the topside of the guide track, a bearing bracket is rotatably supported at the drive roller axles, which bearing bracket in turn supports a pair of counterpressure rollers engageable directly at the underside of the guide track. The counterpressure rollers are spaced from one another in the direction of travel of the guide roller at respective opposite sides of a line through the axle with the drive roller and extending downwardly, such that at least one of these counterpressure rollers is continuously in supporting backing engagement with the guide track so as to assist in assuring a firm driving contact between the guide rollers and the guide track. In preferred embodiments, an additional spring support system is provided between the drive roller and the bracket supporting the drive roller axle and the door, so as to provide an additional biasing force in the downward direction on the drive roller. In preferred embodiments, the guide track is constructed as a C-shaped cross-sectional member, and the bearing bracket includes an extension which protrudes over the top of the guide track as a safety measure to support the door in the event of an axle breakage or the like.

Patent ES-8101386-A1 (ES)
Title: Sonic-actinic cleaning and sterilising of instruments
IPC: A61L2/10
Filed: 1980-01-15
Abstract: A source of actinic radiation, e.g. a UV lamp 4, is positioned to irradiate cleaning liquid 8 in a metal tank 1 (e.g. being mounted inside a tank lid 2 which is shaped as a reflector). There may be a thermostatted heater 13 for the tank. A piezoelectric transducer 10, 11, 12 agitates the liquid 8 ultrasonically. The liquid may be circulated through loop 14 by pump 17, causing macroscopic agitation and allowing liquid and/or entrained waste to be discharged through tap 18. Ambient air may be blown through an aperture 5 in the lid 2, sterilised by radiation, and serve to dry the cleaned articles 9 after discharge of the liquid 8. Operation of pump 17, heater 13, lamp 4 etc may be controlled by an automatic programmer 26. The micro- and macroscopic agitation causes contaminants such as bacteria to be dislodged from all parts of the articles, dispersed in the bulk of the liquid, and neutralised by irradiation before agitation ceases.

Title: Skimmer for removing the surface layer from a stretch of liquid
IPC: C02F1/40
Filed: 1980-03-26
Abstract: A skimmer comprising two main, nested components: a skim vat (1) supported by floats (3) and arranged to float beneath the surface (5) of a sheet of liquid and a spillway (6) supported by floats (7) and free to move telescopically with respect to the skim vat. Liquid is extracted from the bottom of the skim vat (1), thereby lowering the surface (8) of the liquid therein until the spillway (6) which floats with respect to the inside liquid surface (8) has moved far enough down for the rate of flow of surface liquid into the skimmer over the rim of the spillway, to match the rate of extraction via the pipe (4). Two O-ring seals (9 and 11) prevent liquid from escaping from the inside of the skimmer while allowing the nested components to move relative to each other. The skimmer is particularly intended for removing surface pollution from stretches of water.
