Patent ES-295252-A1 (ES)
Title: Method of manufacturing flat glass on a bi-level forming surface
IPC: C03B18/18
Filed: 1964-01-13
Abstract: In the production of heat-finished glass, a sheet or ribbon of glass is supported upon a fluid bed at a temperature at which the glass flows, the edge portions of the ribbon or sheet being supported at a different level from that of the central portion. A continuous ribbon of glass 14 is fed into a tank 18 which contains three molten metal baths 26, 16, 28. The central bath 16 is considerably wider than either of the other two, is separated from them by walls 30, 32 and is at a higher level. The molten baths are heated to a temperature at which the glass will flow. The edges of the ribbon overlie the side baths 26, 28 and when hot they contact these baths and flow to reach their equilibrium thickness. Thus the ribbon thickness at its centre may be maintained different from the equilibrium thickness. As the ribbon progresses down the tank 18 its surfaces become flat and fire-polished. The ribbon is cooled, so that it may be removed without damage, by passing it over successive zones 50a, 50b &c. of the molten baths of progressively cooler temperatures. To heat treat the upper surface radiant heaters are fixed in the tank roof. A <PICT:1021851/C1/1> <PICT:1021851/C1/2> <PICT:1021851/C1/3> <PICT:1021851/C1/4> heated inert gas is maintained above the molten metal (e.g. tin or tin alloy) to prevent oxidation. Alternatively the fluid supports may be gaseous. Beds of modules 108 above the ribbon and 102, 104, 106 below are supplied with hot gases to allow the ribbon to flow. The module beds comprise a plenum chamber 114 which is fed with gas under pressure, which gas is then conveyed to orifices 132 in nozzles 126 within open chambers 110. The orifices 132 ensure that a diffused flow of gas flows into the chambers 110 below (and above) the ribbon. Since exhaust chambers 116 are between each chamber 110 the gases exhaust within the support zone, and thus have virtually no lateral flow.

Patent ES-347680-A1 (ES)
Title: A process and apparatus for the distillation of a liquid and particularly for the production of soft water from sea water
IPC: B01D3/06
Filed: 1967-11-27
Abstract: Liquid, e,g. sea water, is evaporated in a series of evaporator stages lf . . . 1a by means of a countercurrent stream of air (or other gaseous vehicle) circulated through the apparatus by fan 4, and a mixture of vapour and air is withdrawn from each stage and led separately through valves 14a ... 14f to a multi-stage heat exchanger 2a . . . 2f where the vapour condenses. The condensate (desalinated water) is withdrawn from the heat exchanger by pump 7, and discharged from the system via preheater 9. Sea water is fed by pump 6 through preheaters 9, 8, through the coil traversing the heat exchanger 2, and through heater 3 and the heated water is then introduced into the first evaporator stage 1f. Part of the brine withdrawn from the last evaporator stage la is pumped back to the coil of heat exchanger 2, and the remainder is discharged from the system through preheater 8. The temperature of the sea water flowing from preheater 8 to heat exchanger 2 is controlled by thermostat 12. The temperature of the brine flowing between the evaporator stages is controlled by thermostats 15f . . . l5b. The process is preferably operated so that the difference between the temperature and/or specific enthalpy of the liquid and that of the air is maintained lower in the first evaporator stage than the last. An apparatus is described in which the evaporator stages and the heatexchanger are disposed in a common housing.
Patent ES-348949-A1 (ES)
Title: Negative feedback amplifiers
IPC: H03F1/34
Filed: 1968-01-04
Abstract: A three-stage amplifier, e.g. a repeater in a transmission system, includes an overall feedback path from the last to the first stage and local feedback paths associated with the first and last stages, equalizing networks being included in the local feedback paths to shape the gain-frequency response of the amplifier to compensate for the attenuation-frequency characteristic of the cable or line. In the embodiment described, using three cascaded commonemitter stages (the transistors being omitted from Fig. 2) the overall feedback is provided from the emitter C of the last stage to the emitter B of the first stage by impedance Z 2 , and the local feedback paths are provided by impedances Z 1 , Z 3 in the emitter leads of the first and third stages. Impedance Z 1 includes an EQUALISER network the impedance of which is controlled by a thermistor T to compensate for the variation with temperature of the attenuation of the cable. Impedance Z 3 includes an equalizer Z 4 the impedance of which, and consequently the impedance of is preset in accordance with the length of cable. The value of resistor R 2 is much larger than the impedance formed of R 3 and in parallel, so that no substantial variation occurs in the impedance Z 2 . Thus substantial variation occurs only in the local feedback paths so that the loop gain remains constant despite variations in the through gain. The input and output impedances of the amplifier are matched to the respective cables by means of hybrid transformers associated with points A, B and the input circuit and points C, D and the output circuit respectively (Fig. 3, not shown).

Patent ES-361684-A1 (ES)
Title: Process for producing aluminum
IPC: C22B5/02
Filed: 1968-12-20
Abstract: Aluminium is produced from aluminium trichloride by reacting the aluminium trichloride with manganese in a reaction zone at a temperature sufficient to produce liquid aluminium, the manganese being present in a manganese - containing mass in amounts greater than 5% at the beginning of the reaction. The temperature may be above or below the boiling point of manganese chloride so that this product is removed as a gas or is separated from the liquid aluminium by decanting. The process can be incorporated in a two-stage process for the production of aluminium from alumina in the first stage of which alumina is reacted with coke and manganese chloride, e. g. in a blast-furnace, to form manganese and aluminium trichloride, the aluminium trichloride is removed from the furnace as gas, mixed with carbon monoxide, and the manganese is tapped in molten form. The aluminium trichloride is freed from the other gaseous products and reacted with manganese in the second stage to produce aluminium.
