Patent ES-232029-A1 (ES)
Title: Improvements in or relating to the production of vinyl esters
IPC: B01J8/24
Filed: 1956-11-21
Abstract: Vinyl esters are prepared by reacting acetylene and a carboxylic acid using standard fluidized-bed technique, the catalyst, consisting of at least one metallic salt known to activate the reaction and which is capable of regeneration by combustion, being continuously removed from the reaction zone, a deposit of catalytic particles being formed at the lower end of the reactor acting as a substantially water-impermeable pad, regenerated by combustion and recycled to the reactor. The rate of flow of reactants is greater than that which would permit complete reaction. The catalyst is used as a powder, alone or on a support such as silica gel or clay. The particle size may vary from 40-200 microns, 95 per cent of the particles being from 50-150 microns. Zinc and cadmium silicates are the preferred catalysts. The reactants may be used in stoichiometric proportions or one reactant, preferably the acetylene, may be in excess. The gaseous mixture leaving the reaction zone is freed from entrained catalyst by, for example, cyclone separators, filters or electrical precipitators and cooled to condense the vinyl ester, the unreacted reactants being recycled to the reaction zone. The vinyl ester is fractionally distilled to eliminate impurities, dissolved acetylene and unreacted acid, the last two being recycled. The reaction temperature is generally 150-300 DEG C. The reaction zone is preferably surrounded by a cooling jacket. Examples describe the preparation of vinyl acetate and vinyl butyrate, but the process is stated to be applicable generally to vaporizable, acyclic or cyclic, mono- or polycarboxylic, substituted or unsubstituted acids.

Title: Polypeptides
IPC: A61K38/095
Filed: 1960-07-22
Abstract: The invention comprises the cyclic polypeptide of the formula p I, <FORM:0928607/IV(a)/1> and the nonapeptide of the formula II, <FORM:0928607/IV(a)/2> in which R and R1 each represents a protective group for the sulphhydryl group, with the proviso that R and R1 need not be dissimilar, and R11 and R111 each represents a protective group for the amino group with the proviso that R11 and R111 need not be dissimilar and with the further proviso that all of R, R1, R11 and R111 may represent hydrogen atoms and pharmaceutical compositions containing the polypeptide. The groups R and R1 are particularly benzyl groups, R11 a carbobenzoxy group and R111 a p-toluenesulphonyl group. The compounds of the invention may be prepared by condensing the hexapeptide VIII, <FORM:0928607/IV(a)/3> after splitting off the carbobenzoxy group, with the azide of the tripeptide VIII, <FORM:0928607/IV(a)/4> to give the nonapeptide II, treating this with an alkali metal in liquid ammonia to yield the free nonapeptide and oxidising this to the cyclic polypeptide I by air or hydrogen peroxide. The hexapeptide VIII is prepared by condensing N-carbobenzoxy-L-glutaminyl-L-asparaginyl- S-benzyl- L-cysteinyl -azide with L-propyl-e -N-p-toluenesulphonyl- L-lysylgylcinamide prepared by hydrolysis of N-carbobenzoxy-L -prolyl-e -N- p-toluenesulphonyl-L-lysylglycinamide with hydrobromic acid. The tripeptide azide VIII is prepared by condensing N-carbobenzoxy- S-benzyl-L-cysteinyl-L-phenyl-alanine with L-phenylalanine methyl ester and converting the tripeptide ester in the azide with hydrazine. Pharmaceutical compositions comprise the cyclic polypeptide in addition to an inert carrier. The compositions may be formulated as solutions for injection or as nasal sprays. The peptide may be stored in the dry state when mixed with a water soluble carrier, e.g. sodium chloride, to increase its stability. The compositions have vasopressor activity.

Title: Manufacture of electric incandescent lamps
IPC: H01K3/00
Filed: 1964-12-29
Abstract: In making an electric lamp, means for holding one end of a lead-in wire, which may be drawn from a reel, is inserted into an envelope having openings at opposite ends, the wire is cut and shaped and a filament mounted between the cut ends, the envelope and holding means are moved so that the filament is located within the envelope and the ends of the latter are sealed with the lead-in wires passing through the seals. One end is first sealed while the interior of the envelope is flushed with inert gas through the other end, which is then sealed. During the second sealing, further flushing is carried out using inert gas of the composition desired for the final filling. The sealing is effected by heating the glass of the ends of the envelope and compressing it between jaws shaped to produce a flattened press having V-shaped grooves on one or both sides into which the ends of the lead-in wires are finally flattened to form contact terminals for the lamp. Instead of using lead-in wire cut from a reel, a pair of wires cut to equal length are supported side-by-side, one in a holder extending through the envelope, and the filament is mounted between them. The holder outside the envelope is then swung upwards through 180 degrees and the envelope moved up to enclose the filament. The holder may be constructed with one or more openings through which the flushing gas can be directed into the envelope.

Title: A system for braking a moving mass
IPC: G21C7/20
Filed: 1966-09-28
Abstract: A system for braking a movable mass 1 comprises a guide element 2 and a braking part 6, rubbing members 10 for engaging the braking part, first resilient means 12 to urge the rubbing members into contact with the braking part and second resilient means 14 by which the rubbing members are coupled to the mass, the second resilient means, upon relative movement of the mass and the rubbing members induced by engagement of the latter with the braking part, being compressed to provide a further loading of the rubbing members on to the braking part. As shown the moving mass comprises e.g. a cylindrical control rod 1 movable at high speed in a nuclear reactor core 3, and the guide element comprises a rigid rod 2 which is secured to a stationary structure 3 and which has an upper zone 4, which allows unimpeded movement of the control rod 1, a wider lower braking zone 6, and a frusto-conical transition zone 7. The brake is housed in a easing 8 carried by the lower end of the control rod and includes braking elements in the form of cylindrical sectors 10 disposed around the rod 2. The sectors 10 are connected, adjacent their upper ends, by circlips 12, a stack 14 of ring springs 18, 19 with coacting conical surfaces being interposed between shoulders 16 on the lower ends of the sectors 10 and the base 15 of the control rod 1. The rings 18 are continuous, the rings 19 being split at 20. When the control rod 1 falls the brake sectors 10 pass freely over the upper zone 4 of the rod 2 to impinge upon the transition zone 7 and slow down the control rod 1. The momentum of the control rod 1 then imposes an axial compression force upon the stack of springs 18, 19, the rings 19 being radially contracted to force the sectors 10 into heavy clamping engagement with the lower zone 6, of the rod 2 so that the control rod is stopped rapidly. It is stated that braking forces, varying between 1 ton and 4 tons, or even more, have proved possible. The system could also be used with a mass driven, e.g. by an explosive charge, along a horizontal passage. In a modification the system may be used to brake a solid cylindrical mass in a hollow cylindrical guide element.

Title: Method for monitoring the refining of pig iron
IPC: C21C5/30
Filed: 1969-03-21
Abstract: In the control of a pig iron refining process, the rate of decarburization of the pig iron is monitored, by investigation of gases escaping from the converter hood using a photo-cell, germanium photo-diode, or bolometer 1 sensing radiation emitted by the gases, any drift in the output supplied by this detector, which has a fast response time to changes in radiation intensity, (and thus in gas composition) being compensated by comparison of these signals with those produced by a more accurate gas analyser e.g. of the infrared absorption type. This latter detector has a much slower overall response time to changes in the gas composition and so for the comparison of the outputs from the fast and slow detectors 1, 3, in comparator 6, a certain delay e.g. by means of magnetic tape, is introduced at 5 into the output from 1, and also their output is passed through a low-pass filter 4 in order to match the frequency characteristics. of the two signals. Any difference is fed back to control the gain or automatic gain control of the amplifier 2 of the output from 1 and thereby null the difference. An independent control of the amplifier gain may be provided on line 7, to modify the gain to a predetermined extent on the occurrence of a certain operation e.g. addition of the line.
