Patent ES-338177-A1 (ES)
Title: Method for producing sponge iron
IPC: C22B1/26
Filed: 1967-03-17
Abstract: In a process for the gaseous reduction of metal oxides in a plurality of reactors the reducing gas is passed through a body of metal-bearing material in a reactor to cool the material and is then passed through one or more reactors to reduce further bodies of the material. The cooling stage is carried out in two sequential steps in the first of which the gas feedrate to the cooler is essentially the same as that to the reducing stage and in the second of which a portion of the gas leaving the cooler is cooled and recirculated to accelerate the cooling process. The process is exemplified by the production of iron sponge from ferrous ores. In the Fig. steam and natural gas are reacted in a reformer furnace 18 to form a reducing gas containing Co and H 2 and sensible heat which is used in waste heat boiler 42. The gas is then quenched in tower 56 and led from the top thereof to the cooler reactor 10 where, in the first cooling step, it is partially cracked to deposit carbon on the iron sponge product before passing through a quench tower 66, in which water is removed therefrom, and a furnace 74 to the second reducing reactor 12. In the second cooling step a part of the gaseous product of the cooler after passing through the quench tower is led via conduit 130, compressor 128 and conduit 134 back to the feed conduit 62 to cooler 10. Some pre-heated air is introduced into the feed for reducing reactor 10 as described in Specification 2, 900, 247. After passing through reactor 12 the gas is again water quenched and heated prior to passing into the first reducing stage reactor 14 whence it is again quenched in tower 122 and then used as a furnace fuel in conduit 38.

Title: A.c. phase control system responsive to a sensed condition
IPC: G05D23/24
Filed: 1967-09-09
Abstract: An automatic system controlling energization of an A.C. load through a gated semi-conductor switch has a control circuit including a differential amplifier having transistors Q1, Q2, to the control electrodes of which pulsating biasing voltages are applied, one of which has an instantaneous amplitude determined by a sensed condition. Air is circulated in a refrigerator by an A.C. fan motor 11, speed controlled by the temperature sensed by a resistor 56, preferably with a negative characteristic, which with a resistor 55 forms a voltage divider across a pulsating D.C. voltage derived from points 22, 23. When the voltage at the centre junction 36 of a R.C. circuit 45, 47 in each half cycle exceeds that of a point 53, transistor Q1 conducts partly shunting the capacitor 47 through a resistor 61. When at a later time the capacitor 47 voltage exceeds that of another junction 67, transistor Q2 is rendered conductive turning on a third transistor Q3 regeneratively, the voltage across a resistor 75 firing a thyristor 15, which switches a diode budge to a conductive condition. In another arrangement, Fig.2 (not shown) a transformer primary winding (131) replaces the resistor 75, and secondary windings (132, 133) fire reverse parallel connected thyristors (101, 102). The positions of resistors 55, 56 may be interchanged to reverse the temperature-motor speed characteristic.

Patent ES-363451-A1 (ES)
Title: Hydrostatic reactor cavity seal
IPC: G21C13/028
Filed: 1969-02-08
Abstract: A reactor cavity seal comprises a large flat ring used to cover and seal the annulus around the reactor vessel during the refueling time period in which the area is flooded with water. The seal is effected by compressing large diameter O-rings between the flat ring and machined surfaces on the reactor vessel and on a ring set in the surrounding concrete. The O-rings are compressed by using the hydrostatic pressure of the water above the seal ring. Because an absolute seal must be maintained at all times during refueling, auxiliary clamps are utilized to provide the seal compression force required during the low water pressure periods when the refueling canal is being flooded or being drained. These clamps are also utilized to lift and support the seal ring a sufficient distance above the seal surface during plant operation to permit the flow of reactor cavity cooling air.

Title: Cation exchange membranes and their preparation
IPC: C08J5/22
Filed: 1969-04-29
Abstract: A cation exchange membrane made of a homogeneous mixture of (a) a poly-p-vinylphenol, which is optionally halogenated, and which is cross-linked via the oxygen atoms of its hydroxyl groups and substituted by cation exchange radicals, and (b) an inert polymer may be prepared by forming a layer of a solution in and organic solvent of the inert polymer and the poly-p-vinylphenol and then, either successively or simultaneously, evaporating the solvent, cross-linking the poly-p-vinylphenol by reaction with its hydroxyl groups and introducing the cation exchange radicals. The inert polymer is one which does not interfere with the cross-linking of the poly-p-vinylphenol or the introducton of cation-exchange radicals and in particular is inert to halogenated compounds and sultones. Suitable polymers are polyvinyl chloride and a copolymer of vinyl chloride with vinylidene chloride or vinyl acetate. Cross-linking may be effected by dehydration in an inert medium containing hexamethylphosphotriamide or dioxane or by treatment of the salt of the polymer with a compound containing at least two reactive halogen atoms e.g. o- or p-xylylene dihalide or 3,3 - bis(halogeno - methyl) - oxetane. Crosslinking and radical introduction may be effected by reaction with a polysultone e.g. spirobi-2: 21- propanesultone. Exchange radicals may be introduced by sulphonation with e.g. sulphuric acid, oleum, chlorosulphonic acid or a monosultone e.g. propanesultone. The membrane may also contain a quaternary ammonium salt and a hexaalkyl phosphotriamide. In the examples are also used poly(4 - hydroxy - 3 - chlorostyrene), poly(4 - hydroxy - 3 - bromostyrene), methyltrilaurylammonium chloride and tributyl orthophosphate.
