Patent ES-251391-A1 (ES)
Title: Process for the production of water or hydrogen enriched in deuterium
IPC: C01B4/00
Filed: 1959-08-11
Abstract: <PICT:0892087/III/1> In a process in which hydrogen passing to an ammonia synthesis is depleted in deuterium by countercurrent isotopic exchange with ammonia produced, the ammonia is enriched by isotopic exchange with H2O before contact with the H2, and the ammonia after both enrichments is either burnt to nitric oxide and enriched water, or cracked to enriched hydrogen and nitrogen. H2O 1 is converted to H2 in A, e.g. by electrolysis, and the H2 passes through isotopic exchanger B, countercurrent to NH3, to NH3 synthesis C. The NH3 vapour formed is passed, in part, through isotopic exchanger D countercurrent to natural water to produce NH3 (with the natural deuterium content) which is liquefied by compressor or cooler E. The liquid NH3, after addition if desired of catalyst, e.g. platinum or alkali metal amide, through 17, is passed in countercurrent to the H2 through exchanger B, and through filter F to remove catalyst, to combustion or cracking plant G where NH3 is burnt to nitric oxide and H2O, or cracked to N2 and H2. Resulting H2O or H2 is passed through pipe 11 to generator A or to line 2 respectively. Part of the H2O or H2 may be by-passed through deuterium concentration plant H, whence a D-enriched H2O or H2 is recovered, and the D-poor fraction is returned through 13. D may also be recovered by diverting part of the H2 feed at 15 to a concentration plant and returning the D-poor fraction at 16. It is stated that where combustion of NH3 is used, HNO3 formed is neutralized with metal oxide, e.g. quick lime, and an anhydrous salt recovered to avoid D losses.

Title: Thermally controlled electric switch
IPC: H01H37/54
Filed: 1964-10-21
Abstract: A thermal switch has a concave bimetallic plate 1, which changes the direction of its concavity with a snap action when heated, and a movable contact 5 interposed between the bimetallic element 1 and a fixed contact 12, the movable contact 5 comprising a resilient projection 7 extending radially inwards from a ring (6) of electrically conducting material and adapted to be pressed against the fixed contact 12 by movement of the bimetallic plate 1 (see also Figs. 2, 3, not shown). The ring 6 of plate contact 5 is pressed against a circular seating 4 by a ring 8, being locked by an insulating cap 9 which in turn is held in position by the rim 10 of the body 3 of the housing, thus ensuring good electrical contact between plate contact 5 and housing 3. The switch closes a circuit from a terminal 13 to the body 3 and hence via the body of a motor vehicle on which the switch is mounted to its battery, the connection to earth being via a screw plug 15 or a flanged attachment 16 which connects body 3 to the surface of the body the temperature limit of which is to be signalled, the body 3 being adapted to be immersed in a fluid, e.g. engine oil or radiator water, of which the temperature is to be controlled.

Title: Process for coagulation of emulsions with steam containing,as a vapor,a material which reduces emulsion stability
IPC: D04H1/68
Filed: 1965-04-29
Abstract: An emulsion of an organic material of high molecular weight is coagulated within a porous substrate impregnated with the emulsion by subjecting the substrate to the action of steam containing, as a vapour, a material which reduces the stability of the emulsion. The substrate may be a web of fibres, a woven or non-woven fabric or paper. The emulsion may be of natural rubber, natural or synthetic wax, a polymer of isoprene or chloroprene, a copolymer of butadiene with acrylonitrile, styrene or acrylic ester, a polymer or copolymer of an acrylate, vinyl chloride, vinyl acetate or vinylidene chloride, a silicone resin or a mixture of these. It may also contain an additive such as a stabilizing or vulcanizing agent, an antioxidant, a pigment, a thermosetting resin or a catalyst. The material that reduces the stability may be an acid, e.g. formic, an alkali, e.g. ammonia, or an alcohol, e.g. methyl or ethyl alcohol. The emulsion may also contain a material that reduces its stability, but does not coagulate it at ambient temperatures, e.g. ammonium chloride or polyvinyl methyl ether. Non-woven fabrics can be made by impregnating a web of fibres with an emulsion of natural or synthetic rubber or resin, coagulating as above, washing to remove auxiliary agents from the emulsion not wanted in the finished fabric and drying. In the Example a web of flax is impregnated with an emulsion of butadiene-methacrylate copolymer, polyvinyl methyl ether, ammonium chloride and water. The impregnated web is then passed over a boiling mixture of water, formic acid and ethyl alcohol, squeezed, rinsed in water containing sodium carbonate, squeezed again and dried. Other applications are to the impregnation of yarns with rubber, the finishing of textile fabrics and dyeing by binding pigments to fabrics by acrylic emulsions.

Title: Supervisory circuits for checking a repeater in a carrier current communication system
IPC: H04B17/40
Filed: 1965-11-09
Abstract: In a supervisory system for two-way repeaters using different frequency bands for the two directions of transmission and in which repeater testing is carried out using two frequencies, or one frequency and the noise generated in the repeater, lying in the frequency band for one direction of transmission which, when modulated together, produce a difference frequency which lies in the frequency band for the other direction of transmission, the modulating circuit, units 10 to 13, Fig. 1, is connected, on the side of the repeater remote from the testing terminal station, between a pair of branching circuits so that the modulating circuit is isolated from W to E transmissions and faults in the modulating circuit have no effect on transmissions in either direction. Test signal transmission takes place via line 16, hybrid 9, line 14, hybrid 8, line 15, filter 10, amplifier 11, modulator 12, filter 13, hybrid 9, line 16 &c. The hybrid circuits 8 and 9 may comprise bridged-T networks as shown at 17 and 18, Fig. 3, the resonant circuits 20 and 21 being tuned to the test signal frequencies so as to block their transmission over the circuit W to terminals 26 but accept transmission from terminals 26 to the modulator circuit 19. The network 18 is arranged to provide frequency equalization which may replace that normally provided in the repeater. An equivalent form of the networks 17 and 18 is described with reference to Fig. 5 (not shown), this network having only one transformer 27 coupling the line to both input and output of modulator circuit 19.

Title: Liquid cooled continuous metal casting chill mold
IPC: B22D11/05
Filed: 1969-02-07
Abstract: In a mould supported on a frame 6, Fig. 2, and formed of water-cooled plates 1-4 (held together by bolts 5), two opposed plates 3, 4 each comprise two wedge-shaped units 14, 15, so that relative up-and-down movement, e.g., by means of a screw-threaded spindle 17, Fig. 4, and nuts 21, 22, while the bolts 5 are temporarily loosened, widens these sides and broadens the mould cavity, which may have a curved axis. The spindle 17 is located in a bore 16 in one wall unit 14 of a narrow wall 3 or 4 and held from axial movement by a ring portion 18 at its middle, located in a recess (19) at the end of a projection from a backing support 13 for the wall units 14, 15. It has threads of opposed bands so that its rotation causes the nuts 21, 22 to move in opposite directions. Spigots 23, 24 from the nuts cause similar movement of the units 14, 15 since there are slotted holes 29 to receive bolts 25-28 by which the narrow wall 3 or 4 is held on the backing support 13. This support is in two parts 13a, 13b, Fig. 3, between which lie transverse bolts, 30, 31 bearing conical nuts 32, 33 which can spread the parts 13a, 13b to tighten the bolts 25-28. By means of screw-threaded spindles 11 (12) and worm gearing 8, 9, Fig. 3, of drives 7, the narrow walls 3, 4 are also movable towards and away from each other so as to widen or narrow the mould cavity and, since the lower spindles (12) have a smaller pitch, the angle between the narrow walls 3, 4 is changed to modify the cavity taper at the same time. The mould may be divided into two cavities by a wall (34), between the narrow walls 3, 4 and comprising backing parts (13a, 13b) with a pair of units (14, 15 at) each side.
