Title: Process for the preparation of unsaturated higher aliphatic alcohols
Filed: 1956-08-02
Abstract: Unsaturated aliphatic alcohols containing at least six carbon atoms in the molecule are prepared by the catalytic hydrogenation of the corresponding unsaturated acids or their esters with mono- or polyvalent alcohols, in the presence of a catalyst comprising an intimate mixture or combination of chromium oxide, zinc oxide and aluminium oxide, in which the aluminium oxide content is at least 3 per cent by weight of the zinc oxide, preferably 3.5 to 13.5 per cent.  The catalyst may be previously reduced, e.g. at a temperature of 300-350 DEG  C., and a pressure of 250-500 atmospheres, in a current of hydrogen which may be diluted with an inert gas, e.g. nitrogen or carbon dioxide, or the catalyst may be used on a carrier, e.g. asbestos fibre, kieselguhr, silica gel or active carbon, or it may be fluidized. With free acids it is advantageous to use methanol as a solvent. The hydrogen pressure should be between 200 and 400 atmospheres, temperature 300-330 DEG  C., and flow rate 0.5 to 2 litres of raw material per hour per litre of catalyst.  Examples describe the preparation of a catalyst analysing Cr 12.20 per cent, Zn 14.40 per cent and Al 0.52 per cent (see Group III), and its use in hydrogenating oleic acid, tallow fatty acids and palm oil fatty acids.ALSO:A catalyst for the hydrogenation of an unsaturated acid or its ester with a mono- or polyhydric alcohol to the unsaturated alcohol (see Group IV (b)), comprises an intimate mixture or combination of chromium oxide, zinc oxide and aluminium oxide, in which the aluminium oxide comprises at least 3 per cent by weight of the zinc oxide, preferably 3.5-13.5 per cent.  In an example, zinc acetate solution is heated to 50 DEG  C. and chromic anhydride and aluminium acetate added, the mixture heated to 100 DEG  C. and granulated active carbon added.  The heating is continued until substantially all the water is eliminated.  The product is dried at 110 DEG  C. in a stream of nitrogen.  The dry catalyst analysed Cr 12.20 per cent, Zn 14.40 per cent, Al 0.52 per cent.  It may be reduced in a stream of 75 per cent hydrogen and 25 per cent nitrogen at 350 DEG  C. and 500 atmospheres.  It may be used on a carrier, e.g. asbestos fibre, kieselguhr, silica gel, or active carbon, or it may be fluidized.

Title: Process for preparing hydrogen peroxide
IPC: C01B15/023
Filed: 1955-08-22
Abstract: Hydrogen peroxide is produced by the successive catalytic reduction and auto-oxidation of an alkylated anthraquinone, e.g. 2-ethyl anthraquinone, in a solvent medium comprising a chloronaphthalene or an alkoxynaphthalene, e.g. alpha-chloronaphthalene or methoxy-naphthalene.  The solvent medium may also contain dimethyl phthalate.  The solvent may consist of 40 per cent of a -chloronaphthalene and 60 per cent of di-methyl phthalate (Example I) or 50 per cent of a -methoxynaphthalene and 50 per cent of dimethyl phthalate (Example II).  Reducation may be effected by heating the solvent solution to 40-50 DEG  C. and agitating by the passage of hydrogen in the presence of Raney nickel.

Title: Sand blasting device
IPC: B24C5/04
Filed: 1949-09-20
Abstract: 663,604. Sand-blast. KRANS, H. VAN DER. Sept. 20, 1949 [Sept. 30, 1948], No. 24156/49. Class 60 The invention relates to sand blasting devices of the kind in which dry sand is discharged under pressure from a nozzle in the form of a jet enclosed within a tubular stream of water, the water serving to wet the sand after the latter has impinged against the surface of an object to be cleaned and thereby prevent the sand particles or dust from remaining in the air. A device of this kind in which the nozzle is located within a casing to which are connected supply conduits for the sand and water respectively, is characterised in that said nozzle is secured to a tubular conical member by the casing, the latter being screwed to one end of said member and having an internal flange engaged with the nozzle, the other end of said conical member being provided with means for connecting it to the sand supply conduit. The device consists of a conical body 1 to which a pipe 2 is connected, the pipe having a collar 16 secured thereto by fastening means 3, 4, and the enlarged inner end 5 of the body 1 being internally screw-threaded to receive the threaded end of the collar 16. The central body 1 discharges into a nozzle 7 provided with a wear-resistant lining 6. A tubular casing 8 mounted on the outer end of the central body 1 surrounds the nozzle 7, the inner diameter of the casing being greater than the outer diameter of the nozzle 7. The casing 8, which terminates in a mouth 9 beyond the outer end of the nozzle 7, is formed with a connection 11 communicating with a water supply and having a bore 14 leading to the interior of the casing. The inner end of the casing 8 is internally threaded at 13 to receive a threaded part 12 of the body 1. The nozzle 7 is seated within the outer end of the body and is held in position by the engagement of an internal flange 8a of the casing 8 with an external flange 7a on the nozzle. That portion of the body 1 extending between the conduit 2 and the nozzle 7 is provided with a rubber lining 15 having a conical bore, the larger diameter end of this bore being equal or substantially equal to the internal diameter of the conduit 2 and the smaller diameter end of the bore being about equal to the internal diameter of the adjacent end of the nozzle and communicating directly with the nozzle. The casing 8 is tapered so that the cross-sectional area of the space 10 between the nozzle and the casing gradually decreases towards its outer end. If the surrounding layer of water is not required, e.g. when sand blasting ships in the vicinity of the chocks, the casing 8 is replaced by a flanged nut engaging the flange 7a of the nozzle 7.

Title: Improvements in separators for pressure vessels
IPC: F16J13/02
Filed: 1959-09-24
Abstract: 935,744. Hydraulic accumulators. J. MERCIER. Sept. 24, 1959 [Sept. 29, 1958], No. 24291/60. Divided out of 935,743. Class 69 (2). A separator for dividing the interior of an hydraulic accumulator into two compartments comprises a flexible partition 61 having a mouth and a rigid annular support member to which the partition is bonded and thereby secured to the accumulator, the support member extending in the radial direction and the partition extending axially away from one axial face of the support member. The inner fibres of the material of the partition adjacent the support member are shorter than those near at least one wall surface of the partition so that deformation of the partition due to tension causes less movement of the external surfaces than of the interior of the material. In order that the external fibres shall be longer than the internal fibres, the cross-section of the separator may be shaped as shown at 22, 23 and 26 in Figs. 2, 3 and 4, respectively, and adhered to flat or convex support members 21, 24 and 27. If the separator is suitably shaped it may be adhered to a concave support member. In an embodiment incorporating the arrangements shown in Figs. 2 and 3, the support member 63, Fig. 5, has a rounded inner portion 64 and the separator 61 is clamped between a casing 60 and cover 62 by an annular element 68. In another embodiment, the support member 72, Fig. 6, has a rounded inner portion and is moulded in the partition and clamped between the casing 70 and cover 73. A guiding element 79 limits the movement of the separator. The support member may have undulations to increase the adhesive area.

Title: Improvements in or relating to superconductive stores
IPC: G11C15/06
Filed: 1968-05-22
Abstract: 1,220,257. Superconductive data stores. SIEMENS A.G. 22 May, 1968 [23 May, 1967], No. 24298/68. Heading G4C. In a superconductive store, a replacement section for use in the event of failure in a main section is controlled by associative storage cells linked with lines going to a main section decoder. In Fig. 1, address lines 8 control a cryotron decoder 3 to select a main word line 2, 21 of the store (bit lines, not shown), and pass through cryotron associative storage cells 13, 14, respective groups (rows) of which relate to respective replacement word lines 5, 51 of the store. If a main word line 2, 21 is faulty it is addressed on lines 8 and one of lines 15 is energized so that the address is stored in a group of the associative cells 13, 14. If the faulty main word line is subsequently addressed the group recognizes the address causing a respective line 9, 91 to be superconducting thus blocking all but a corresponding one of the replacement word lines 5, 51 by means of cryotrons 7, 71 and blocking the main word line using cryotron 19. If the addressed main word line were not faulty, none of the lines 9, 91 is superconducting and a line 11 blocks the replacement word lines at cryotrons 6.

Title: Improvements in diazotization processes
IPC: C09B41/00
Filed: 1955-08-26
Abstract: In a process for the diazotization of amines there are simultaneously and continuously introduced into a precooled solvent or diluent, in which the reaction mixture accumulates in the course of the reaction, a diazotisable amine in the free state or in the form of a salt, if desired in admixture with a suitable solvent and a diazotizing agent, i.e. an agent yielding nitrous acid under the reaction conditions and also one or more acids and, if desired, one or more diluents and/or catalysts known to be suitable for the desired diazotization reaction, the rate of addition of the individual reactants being regulated according to the desired composition of the reaction product and the latter being continuously withdrawn.  The process may be carried out using a single stirring vessel, optionally followed by an additional reaction chamber into which the mixture flowing off may be led to avoid contamination with fresh reactants and to complete the reaction, or the reaction mixture may be pumped in a cycle, preferably with turbulent flow.  An apparatus is described with reference to the Figure (not shown) for carrying out the process. Starting materials mentioned include mono- and polyamines of aromatic character derived e.g. from benzene or hydrocarbons with condensed benzene nuclei or with one or more attached heterocyclic rings, e.g. quinoline or heterocyclic compounds such as thiophene, pyridine and pyrazole, optionally with aliphatic or araliphatic side chains and other substituents such as phenolic, carboxylic and sulphonic acid and halogen substituents.  Diazotizing agents specified include inorganic nitrites with mineral acid, alkyl nitrites and nitrosyl-sulphuric acid.  Examples relate to the diazotization of aniline (1); 1-phenyl-2 : 3-dimethyl - 4 - aminopyrazolone - (5) (2); sulphanilic acid (3); p-nitraniline (4); 2:4-dinitraniline (5); and para-amino-para1-methoxy diphenylamine hydrochloride.
