Abstract: 1470932 Making wire; altering physical properties SUMITOMO ELECTRIC INDUSTRIES Ltd 7 Feb 1975 [12 Feb 1974] 5361/75 Headings B3A and B3V A method of manufacturing electric conductor wires of aluminium or aluminium alloy comprises the steps of hot working the material, then cold working it to reduce its cross-sectional area by 80% or more, annealing at 100‹ to 280‹ C., cold drawing it by 50% area or more, and then continuously annealing it. The alloy should provide a conductor of 60% IACS conductivity, and subject to this may contain Fe, Cu, Mg, Si, Ni, Co, Be, Sb, Zr, Y, Sc, rare earth elements, Ag, Cd, Ca, Ge, Bi, In, Sn, Zn, Nb, Mo, Ti, or V. After the continuous annealing, further cold drawing by 10% to 30% area may be carried out. In one set of examples, a 99À8% Al semicontinuous cast ingot is hot rolled to 9À5 mm. diameter wire, then cold drawn to 2 mm. diameter. Specimens of this are annealed under conditions ranging from 10 hours at 130‹ C. to 2 hours at 230‹ C., and then cold drawn by 85% area. The resulting wire is then fed into a continuous treatment line where it is annealed by electric resistance heating and cold drawn by 13% area to produce “ hard aluminium, insulated with plastics material, cooled, and coiled, being subsequently stranded.

Patent GB-864666-A (GB)
Title: Production of unsaturated aliphatic aldehydes
Inventor: BARCLAY JOHN LYNN
IPC: B01J23/843
Filed: 1959-02-17
Abstract: Acrolein or methacrolein is prepared by reacting at an elevated temperature in the vapour phase propylene or isobutene respectively with oxygen in the presence of an oxidation catalyst comprising antimony oxide.  The antimony oxide catalyst may be derived from an antimony compound which is partially or completely converted under the reaction conditions to an oxide of antimony.  The catalyst may comprise antimony oxide alone or in combination with another polyvalent metal oxide such as an oxide of molybdenum, tungsten, tellurium, copper, titanium or cobalt. The activity of the catalyst is frequently improved by a prior heat-treatment, for instance at 500-1100 DEG C.  A particularly good catalyst is one comprising (a) a mixture of oxides of tin and antimony and/or (b) a compound of antimony, tin and oxygen.  The catalyst may be used on supports, such as alumina or silica and the process may be carried out as a fixed bed or as a fluidised bed process.  The proportion of olefine in the feed is preferably between 2 and 10% by volume and the proportion of oxygen between 2 and 15%.  Preferably the reaction is carried out in the presence of an inert diluent e.g. nitrogen, propane, butane, isobutane, carbon dioxide or steam.  The preferred diluents are steam and nitrogen or mixtures thereof.  The preferred temperature range for carrying out the reaction is 300-500 DEG C.  The aldehyde may be recovered from the reaction mixture by conventional methods, e.g. by counter current extraction with water, preferably at a pH at or below 7, followed by fractional distillation.  Specifications 625,330 and 648,386 are referred to.ALSO:A catalyst for use in the oxidation of propylene and isobutene with oxygen to acrolein and methacrolein respectively comprises antimony oxide alone or in combination with another polyvalent metal oxide, such as an oxide of molybdenum, tungsten, tellurium, copper, titanium or cobalt.

Abstract: Alcohols and esters of the general formula CH3-R1-A-R2-X1, where A represents -CH2-CH=CH-CH=CH- or -CH=CH-CH=CH-CH2-, and R1 and R2 represent straight chain alkylene groups which collectively contain from 7 to 11 carbon atoms and X1 represents a hydroxy-methyl or aliphatic acyloxy group, are prepared by partially hydrogenating a diacetylenic compound, CH3-R1-C­C-CH2-C­R2-X2, wherein X2 represents, a hydroxy-methyl, an etherified or esterified hydroxy-methyl group, a carboxy or esterified carboxy group, or an aldehyde or acetalised aldehyde group, in the presence of a catalyst to form a compound, CH3-R1-CH=CH-CH2-CH=CH-R2-X2 and in either sequence where the two steps are involved, isomerising the partially hydrogenated product by treatment with a strongly alkaline agent, and transforming, if necessary, the group X2 therein into a hydroxy-methyl or aliphatic acyloxy-methyl group by conventional methods.  The partial hydrogenation may be in the presence of lead-inhibited palladium catalyst, and the isomerization carried out using strong alkalis at elevated temperatures, preferably in an anhydrous solvent such as butanol, ethylene glycol or glycerine, or by treating with sodium or potassium amide in liquid ammonia between, for example -30 DEG C. and +20 DEG C.  In Examples (1) a mixture of tetradecadien-(6 trans, 8 cis)-ol-(1) and -(5 cis, 7 trans)-ol-(1) is obtained by the hydrogenation and isomerisation of tetradecadiyn-(5,8)-ol-(1), (2) tetradecadien-(5,8)-ol-(1) is obtained from tetradecadiyn-(5,8)-oic-(1) acid, (3) a mixture of hexadecadien-(10 cis, 12 trans)-ol-(1), and -(11 trans, 13 cis)-ol-(1) from hexadecadiyn-(10,13)-oic-(1) acid and (4) a mixture of hexadecadien-(9 cis, 11 trans)-ol-(1) and -(10 trans, 12 cis)-ol-(1) from hexadecadiyn-(9,12)-oic-(1) acid.  The compounds have insect attracting properties and in particular hexadecadien-(10,12)-ol-(1), are suitable for mixing with insecticides.  Specification 911,107 is referred to.

Title: Improvements in or relating to the manufacture of carbon rod arc electrodes
IPC: H05B31/16
Filed: 1932-02-23
Abstract: Carbon rod arc electrodes undecomposable by water are impregnated in the surface stratum only with a water-resistant material such as a cellulose lacquer.  The electrode may be coated with metal in addition.  In one method of impregnating the electrode, as shown in the Figure, the carbon rod 1 is fed forward through a chamber 5 packed with absorbent washers 6 which are kept soaked by gravity flow of cellulose acetate from a tank 7 to a lower tank 8.  The washers are dimensioned to give a smooth sliding fit with the carbon 1.  The rod 1 then enters a chamber 3 containing aluminium powder fed from a hopper 13.  Rubber or felt washers 10, 11 prevent escape of the powder which is rubbed into the rod by gravity pressure and by the brushing action of the washer 11.  A wiper unit 4 removes excess metal powder from the rod and rubs the powder further into the electrode.  The impregnating, powdering, and wiping means may be disposed in adjacent compartments of a single housing.  In a modification the impregnating washers are spaced apart and arranged alternately with metal powder chambers.  In another modification the metal powder may be suspended in the impregnating liquid.  Or a metal coating may be applied by eletroplating after cleaning the impregnated surface.  Or carbon rods may be allowed to roll down an inclined plane covered in varnish-soaked felt and tumbled into a box filled with <PICT:0395073/III/1> metal powder.  The metal coating may be of bronze, aluminium or copper.  Instead of a metal other conductive substances such as iron oxide may be used.  The carbon rod may be metal coated by a well-known process and afterwards impregnated; the liquid is stated to pass through the coating.ALSO:Carbon-rod arc electrodes undecomposable by water are impregnated in the surface stratum only with a water-resistant material such as a cellulose lacquer.
