Patent ES-262528-A1 (ES)
Title: Process for the recovery of aluminum from aluminum-aluminum carbide mixtures
IPC: C22B21/06
Filed: 1960-11-17
Abstract: Aluminium is extracted from aluminium-aluminium carbide mixtures by using a flux containing at least one alkali metal halide and/ or at least one alkaline earth metal halide in a proportion by weight less than that of the mixture to form two phases which are separable. One phase comprises liquid aluminium, the other a slurry of the flux and aluminium carbide which becomes progressively more viscous as the carbide concentration increases until it finally congeals. The proportion by weight of the flux is preferably equal to that of the carbide in the Al-Al4C3 mixture. The flux may contain AlCl3 to lower the surface tension thereof and is preferably heated to a temperature of 100 DEG C. or more above its melting point in the pure state, e.g. 850-1000 DEG C. The temperature of the flux may be lowered during the course of the process to get a better separation of the aluminium and a small quantity of an inert substance (Al4C3 or Al2O3) may be added near the end of the process for better separation. Specifications 865,861 and 893,345 are referred to.

Title: Electrolytic recording sheets
IPC: G03G5/147
Filed: 1963-01-16
Abstract: An electro-photographic material suitable for electrolytic development has over the photo-conductive layer, though not necessarily in direct contact therewith, a continuous, glossy, transparent, cohesive, and water-permeable layer containing a film-forming silica, this layer being substantially free of alkali-metal ions. The silica-containing layer is intended to improve the contrast of the developed image and is stated to be more suitable for this purpose than layers of polyvinyl alcohol, polyvinyl pyrolidone, dimethyl hydantoin formaldehyde, or gelatin. A layer containing a developer material may be provided between the photoconductive layer and the silica-containing layer or developer materials, such as electrolytically-reducible dyes or salts of zinc and silver, may be included in the silica containing layer. A wide variety of other materials may be added to the silica containing layer including inorganic materials, filter dyes, and other organic materials. In the embodiments given, however, silica-containing films are coated directly on to photoconductive layers. Three developers are given for such materials. One consists of an aqueous solution of specified quantities of silver nitrate, ethylene thiourea, magnesium acetate, and acetic acid. Cathodic development is used, the current being passed intermittently to avoid polarisation troubles. A second developer consists of an aqueous solution of silver nitrate and magnesium nitrate. Again intermittent development is used. The third developer is an aqueous solution of nickel chloride, ammonium chloride, and ammonia (pH 6. 5). It is suggested that with silver developers the surface may be treated with known photographic sensitizers such as quatenary ammonium halides, saccharine, and ethylene thiourea.

Patent ES-354115-A1 (ES)
Title: Improvements in or relating to automatic mooring winches
IPC: B66D1/48
Filed: 1968-05-20
Abstract: A mooring winch has its drive automatically controlled to maintain a preset tension in a mooring rope 11 by a moment balance mechanism comprising a planetary gear 4, 5, 12 which forms part of the drive to the winch drum and causes deflections of a spring balance 18, which in turn controls the power supply to the winch motor 1. A gear-wheel 8 fixed to the drum shaft 9 is driven by a gear-wheel 7 mounting a frame 6 for planet gears 5, the latter engaging both a sun-wheel 4 secured to the crank-shaft of the drive motor 1, and an annular gear 12. The latter is pivotally mounted on links 13, 14 which when the gear 12 rotatably deflects in proportion to the moment differential between the drive motor 1 and the tension in the rope 11, transmit this deflection through links 16, 17 to the balance 18. A cable 29 for transmitting deflection in the spring balance 18 to a control valve 2 of the motor 1, operates through a linkage 31, which is adjustable relative to the valve 2 to permit a setting corresponding to any desired tension in the rope 11. A lever 32 is provided in association with the linkage 31 to permit manual control of the winch motor which may be steam, hydraulic or electrically powered.
Patent ES-355850-A1 (ES)
Title: Bi-directional capacitive load driver
IPC: H03K17/60
Filed: 1968-07-06
Abstract: In a capacitor charging circuit comprising a positive charging circuit 42, a negative charging circuit 44 and the capacitor, such as a crystal 46 connected in parallel, the positive and negative charging circuits 42, 44 each include a diode 64, 36, a Zener diode 40, 38, and a respective voltage pulse generator 47, 48, the pulse generators are operated alternately and the diode and Zener diode in each charging circuit are poled such that discharge of the capacitor is blocked by the diode in one charging circuit and by the Zener diode in the other charging circuit in accordance with the polarity of the capacitor voltage. To positively charge the crystal, which may be used to change the state of polarization of linearly polarized light, a switching pulse 86 (Fig. 4) is applied at 50 to turn on switching transistor 54. This generates a pulse in secondary 62 which is passed by diode 64 to charge the crystal 46. The Zener diode 40 conducts and maintains the voltage across it, e.g. at 2000 volts. The diode 64 blocks discharge of the capacitor and the Zener voltage across the Zener diode 38 blocks discharge via the negative charging curcuit 44. Leakage of charge is compensated by applying sustaining pulses 88 at 58 which produce an output Fig. 4e, having a slight sawtooth superimposed on the load voltage. Similarly the negative charging circuit is operated by switching transistor 74 when a switching pulse 90 and sustaining pulses 92 are applied at 70, 78. The transformer 48 is wound so that the upper end connected to diode 36 is negative. The capacitors 68, 84 act as filters. The Zener diodes 40, 38 may consist of a plurality of series connected Zener diodes. The amplitude and duration of the pulses induced in the charging loops may be controlled by controlling the amplitude and duration of the current through the primary of each transformer.

Title: Raster distortion correction circuit
IPC: H04N3/233
Filed: 1968-08-13
Abstract: In an arrangement for correcting vertical pin-cushion distortion in the raster on a cathoderay display tube by coupling a correction waveform into the vertical deflection circuit the waveform is produced under the control of two trains of pulses of horizontal repetition frequency and opposite phases. The pulse trains 66, 68 (Fig. 1) are derived from the horizontal scan transformer 22 and supplied via respective capacitors 62, 64 and resistors 74, 78 to respective diodes 76, 80 which are rendered progressively more conductive (diode 76) and less conductive (diode 80) by a sawtooth wave 60 (derived via an integrating circuit 58 from the waveform 54 at the output of the vertical deflection. amplifier 40) so that an increasing and decreasing portion of the two pulse trains respectively is shunted to earth via circuit 58 centered about zero potential as shown at 82 and 84. The latter pulse trains are then applied to respective diodes 94, 98 and the transmitted pulse trains 96, 100 combined via respective amplitude control adjustable resistors 102, 104. The combined output at the junction of the latter resistors is then supplied to an L.C. circuit 106, 108 resonant at the horizontal frequency and via resistor 112 capacitor 114 and triode 116 to the primary winding of a transformer 120 the secondary 122 of which resonates at the horizontal frequency and is connected to the vertical deflection coils 50, 52. L.C. circuit 106, 108 produces a sinusoidal voltage waveform 110 (this being a sufficiently close approximation to the ideal parabolic correction waveform) having the required decreasing and increasing amplitude characteristic with a reversal of phase between the two portions but since the pulse trains which cause circuit 106, 108 to ring to produce the waveform occur during line retrace intervals it is necessary to change the phase of waveform 110 by 180 degrees so that the correction is effected during the trace periods. This phase change is produced in two stages, the first being on 90 degree phase shift produced by inductance 106 together with resistor 112 and capacitor 114 and the second an additional 90 degree phase shift produced by the action of the vertical deflection coils 50, 52 in converting the voltage waveform 110 into current counterpart. The latter is thus combined with the normal sawtooth deflection current 53 and provides the waveform required for correction of pincushion distortion of the kind shown in Fig. 2.

Patent ES-374175-A1 (ES)
Title: Electronic printing input-output station
IPC: B41J2/34
Filed: 1969-12-03
Abstract: An input-output station for a remote time-shared computer is described which has a high-speed electronic printer output and a keyboard encoder input. The output from the keyboard is temporarily stored in a one character buffer which serves as the input to the electronic printer and to an accumulator register comprised of parallel MOS shift registers where an entire line of characters are stored as they are printed. Only after the accumulator is full does the station respond to a poll character from the central processing unit to send the data through a parallel-to-serial converter and over the data link to the computer. The input to the computer is at the maximum rate at which the data can be transmitted, thus occupying the computer for only a fraction of the time otherwise required for the operator to enter the data direct from the keyboard. Data sent from the computer is routed through the converter to the buffer and is printed out by the high speed electronic printer at the maximum rate. This system provides for most efficient use of the computer by the input-output stations.
Patent ES-384160-A1 (ES)
Title: Ignition circuit for spark plugs of internal-combustion engine
IPC: F02P3/08
Filed: 1970-09-16
Abstract: The ignition circuit of a spark plug of an internal-combustion engine includes a storage condenser in series with a controlled rectifier which is periodically triggered under the control of an engine-driven cam switch by a blocking oscillator comprising a transistor with grounded emitter in series with the primary of a coupling transformer. One secondary winding of that transformer is inserted, together with a pair of diodes, in a charging path for the storage condenser while another secondary winding lies between the emitter of the transistor and its base which is connected through a feedback resistor to the collector thereof and via an R/C network to the gate of the controlled rectifier. During the open phase of the cam-switch cycle, the base is grounded through the last-mentioned secondary winding which is so poled as to intensify a firing pulse capacitively transmitted to the base upon the opening of the switch at the same time the controlled retifier is turned on to discharge the previously charged storage condenser through the ignition circuit, whereupon the transistor cuts off and the condenser is recharged by the reversed transformer voltage.

Patent ES-411033-A1 (ES)
Title: Radial tire with additional sidewall reinforcement
IPC: B29D30/08
Filed: 1973-01-27
Abstract: A radial tire is formed with the usual radial carcass and, in each sidewall, an additional reinforcement ply comprising cords arranged circumferentially of the tire and having a stiffness which generally increases with increasing distance from the axis of the tire from a minimum value at the edge adjacent to the bead wire to a maximum value at the other edge. In manufacturing the tire on a building drum, the cords selected to form the additional ply comprise a fragile core portion and a portion wound in a helix around the core and capable of elongation by rupture of the core and increase of the pitch of the helix. During the subsequent shaping, the cords of the additional ply automatically acquire the proper stiffness. This produces a tire providing improved road qualities and passenger comfort.
