Inventor: RANSFORD ROBERT BOLTON
IPC: C08L7/02
Filed: 1916-12-14
Abstract: 111,906. Ransford, B. B., (Ilcken, C. A., and Down, St. V. B.). Dec. 14, 1916. Latex, coagulating; india-rubber, preparation of and preserving.-Latices; inferior, dirty or imperfectly coagulated rubbers; raw, tacky, or scrap rubbers; or rubber gums in any form are treated in the cold with asphalt, bitumen, tar, pitch or the like, wholly or in part dissolved. The treatment may be combined with the processes described in Specifications 8487/15, 110,566, and 111,907. Suitable solvents are petroleum benzine, coal-tar naphtha, pyridine, and terpenes, which may be mixed with alcohols. Strained latex may be treated with a 10 per cent. solution of asphalt containing a coagulant, or the coagulant may be subsequently added and may comprise a polyvalent alcohol or a derivative thereof which is soluble in water, such as glycerine or glycerine esters. This treatment may be followed by that described in Specification 8487/15, or may be preceded by that described in Specification 110,566 and then, as soon as a spongy clot has formed, a mixture of alcohol and petroleum benzine with a solution containing 5-10 per cent. of asphalt is added, for example ¢ oz. or more of asphalt to every gallon of latex containing 15 per cent. or more of dry rubber. Raw rubbers &c. are merely immersed in the asphalt &c. solution for about 2 seconds.
Patent GB-1011423-A (GB)
Title: An improvement in or relating to centrifugal casting
IPC: B22D13/04
Filed: 1962-05-10
Abstract: A machine for centrifugally casting metal articles, e.g grinding and crushing balls, comprises a two-part die simultaneously rotatable about two axes which intersect within the mould cavity, and means whereby the speed of rotation about one axis relative to the speed of rotation about the other axis can be steplessly varied.  The mould 10, 12 is rotatably supported in brackets 19 on a turntable 18 rotated about a vertical axis by a variable speed motor 24.  The die part 12 carries a pinion 40 engageable with a gear-wheel 42 driven by a variable speed motor 50 to rotate the mould about a horizontal axis 14.  For pouring the gear wheel is swung to one side, the die locked against rotation about the horizontal axis by a wedge-actuated, spring loaded pin 60, and a ladle 72 moved into position above the die. Rotation about the vertical axis may continue during pouring. The ladle is then removed, the gearwheel 42 swung back above the die and its speed adjusted by reference to tachometers 54, 56 to the speed of rotation of the die so that the gear wheel 42 and pinion 40 may be brought into mesh.  A brake 52 may then be applied to slow down and bring to rest the gear-wheel 42 <PICT:1011423/C1/1> <PICT:1011423/C1/2> so as to cause the die to rotate about the horizontal axis.  In a modification a bevel gear driving the die about its horizontal axis is driven from below the turntable by a variable speed motor so that the gear need not be disengaged for top pouring of the die.  The locking pin is hydraulically actuated. Instead of variable speed motors, fixed speed motors and variable speed gear units may be used.  The pressure within the die cavity may be raised by the insertion of a tablet which will give off a gas when in contact with the melt.  Glass.-Metal and glass may be cast successively to form an article having a double wall.

Patent GB-1092100-A (GB)
Title: Improvements in and relating to the production of fuel gas
IPC: C10G9/38
Filed: 1964-05-02
Abstract: A fuel gas is made from a distillate fraction obtained from crude hydrocarbon material, e.g. crude petroleum or a petroleum fraction, by splitting the material at atmospheric pressure, e.g. by flash distillation, into the distillate fraction and a residue fraction, and separately gasifying the fractions at not less than 20 kg./cm.2 pressure.  The resultant gases may be combined. The gasification processes are catalytic hydrogenation for the distillate to produce a rich gas, and partial combustion with oxygen (or air) and steam for the residue to produce a lean gas, and the hydrogen for the hydrogenation process may be provided by the lean gas, after partial or total co-conversion and CO2-removal, see Figure (not shown).  In this case, a portion of the lean gas is led off immediately after the partial combustion process, and further portions after each conversion, for mixing with the rich gas.  Alternatively, the hydrogen may be provided by steam reforming part of the distillate, or by recycling rich gas from the hydrogenation step, after co-conversion.  The properties of the final gas may be controlled by controlling the distillate/residue ratio, by varying the proportion of rich to lean gas, and by (a) submitting the rich gas to steam reforming, or (b) submitting the lean gas to methanation. A specific example is described, in which characteristics of the crude material and of the fractions, compositions of the various gases, and gasification temperatures and pressures are given.

Abstract: 492,413. Pneumatic separators. COMPAGNIE DES MINES DE BRUAY, and SOULARY, P. July 5, 1937, No. 18699. Convention date, Aug. 31, 1936. [Class 117] Relates to apparatus for the separation of materials of different density such as described in Specifications 320,207, [Class 117], 352,943, 371,086, and 460,742 and consists in arrangements for obtaining multiplication of the fractions emerging at the end of the separating compartments without superposed cutters and for utilizing an air pressure appropriate to the materials under treatment. As shown in the Figure, the raw material such as coal is fed to a perforate table 2 and after treatment by an upward air current and mechanical jigging action is divided into an upper and lower layer by a cutter 1. The upper layer is delivered to two compartments 8 and the lower layer to a compartment 3 of a second table. The pressure in the air chambers under the compartments 3, 8 is independently regulated to correspond with the different mean densities of the material in these compartments. Single cutters 5, 9 at the ends divide the materials in each compartment into two layers. The upper layer in the compartments 8 consisting of the lowest density material such as coal in a coal cleaning apparatus, is delivered by side shoots C<3>. The lower layer in the compartment 3 consisting of the densest material such as schist is delivered at 6. The upper layer in the compartment 3 and the lower layer in the compartments 8 are products of mixed density and are delivered together. They are then preferably returned to the head of the machine for a repetition of the treatment. In a modification, the table 2 on to which the material is fed may be of the kind described in Specification 460,742 in which a preliminary classification of the material takes place with delivery of the least dense product such as coal. The remaining two fractions are then treated in a following table divided as shown,into parallel treating compartments. A further modification consists in arranging two series of tables in parallel and feeding light mixed products from the end of the first series back to the original feed point and the heavy mixed products from the first series along with the mixed products from the end of the second series, to the head of the second series. The Specification as open to inspection under Sect. 91, comprises also an arrangement in which two series of tables are arranged in parallel and the mixed products from the first series are fed to the head of the second series. In this arrangement the tables are not divided into longitudinal compartments adapted to take selected products from the preceding table. This subject-matter does not appear in the Specification as accepted.
