Title: Modified polystyrene moulding compositions
IPC: C08L25/06
Filed: 1955-06-20
Abstract: A moulding composition having improved toughness comprises a mixture of 100 parts mouldable polystyrene with 1-50 parts of a chemically heterogeneous copolymer of 30-90 per cent of butadiene and 70-10 per cent of styrene.  The heterogeneous copolymer exhibits a wide variation in the ratio of butadiene units to styrene units in the individual molecules and may be prepared, for example, by an aqueous emulsion method in which at least 40 per cent of one of the monomers, preferably styrene, is withheld until 40 to 60 per cent of the other monomer has polymerized.  The polymerization may be performed batchwise or the styrene added continuously or incrementally.  The composition may be made by blending the copolymer, in dry powdered form, with granulated polystyrene on a rotary blender or rolling mill or by mixing less than 50 per cent of polystyrene latex with the copolymer, drying and blending with additional granular polystyrene. Dyes, pigments, lubricants, fillers, plasticisers and stabilizers may be included in the composition.

Title: A workpiece handling mechanism for a grinding machine
IPC: B24B41/00
Filed: 1960-05-23
Abstract: 878,006. Grinding. CINCINNATI MILLING MACHINE CO. May 23, 1960 [Sept. 22, 1959], No. 18076/60. Class 60. A grinding machine comprises a driver 20, Figs. 1 and 5, for rotating a workpiece 17, a member 61 movable from a loading position wherein it engages a workpiece for conveying it to a grinding position, and means for shifting the member towards the driver so as to hold the workpiece against the driver in the grinding position. The workpieces, which are of annular form, are stacked in a shoot 80, Figs. 1 and 3, and can be successively ejected by a piston-and-cylinder device 83 through a bore 82 on to a pin 69, Fig. 4, on the end of a spindle 61 which is freely-rotatable in an air bearing 50 in a housing 34. The housing is secured to a shaft 33, Fig. 3, formed with a pinion 35 engaged by a rock 36 on a piston 37 movable in a cylinder 38 by hydraulic pressure in a circuit containing automaticallycontrolled solenoid-operated valves. The end of the pin 69 is in close proximity to a curved surface 77, Fig. 5. which retains a workpiece on the pin when hydraulic pressure is admitted to one end of the cylinder 38 to rotate the housing so as to carry the workpiece from the shoot to the grinding position wherein it abuts a pair of adjustable supports and the surface 20a of the driver 20 which may be magnetic and is rotated in a head 18. Air is then supplied to the bearing 50 to cause the spindle 61 to float, the air also acting on an end surface 61b of the spindle which is thus shifted to press the workpiece against the surface 20a of the driver ; the air bearing permits tilting of the spindle and workpiece. The grinding wheel 15 is then automatically fed into the workpiece and, after a time delay, retracted. Thereafter, the hydraulic system causes the housing 34 to be rotated in the reverse direction to a position past the loading position. Towards the end of this movement, an eccentricallydisposed guide 92, Fig. 5, engages a groove 93 in a sleeve 62 which is moved axially on the spindle 61 to push the finished workpiece from the spindle into a tray 88, the housing then being moved to the loading position to receive the next workpiece. The headstock 18, supports, and means for feeding the workpiece to the grinding position are mounted on a plate 29 which is adjustable about a bolt 94 to enable tapered workpieces to be ground and the plate 29 is mounted on a cross-slide to permit lateral movement of the workpieces.

Title: Improvements in or relating to process for the production of carbon monoxide and hydrogen
Inventor: TEICHMANN CHARLES FREDERICK
Filed: 1953-06-30
Abstract: <PICT:0755946/III/1> Hydrogen and carbon monoxide are produced by partial combustion of a fluid hydrocarbon and a free oxygen-containing gas by introducing the hydrocarbon and oxygen-containing gas in suitable proportions into the combustion section of a gas turbine at elevated pressure, the combustion section comprising a reaction space free from packing and catalyst and having an internal surface area not greater than 1.5 times the surface area of a sphere of equal volume, effecting combustion therein at 2000 DEG F.-3000 DEG F. and immediately reducing the temperature of the product gas to 600 DEG F., the reduction in temperature from at least 1600 DEG F. to 600 DEG F. being effected in the blading of the turbine to prevent carbon formation.  Natural gas, which may be preheated to 400-1200 DEG F., and gas containing at least 40 per cent free oxygen are introduced at 6, 8 respectively, into mixer 7, and thence into insulated pressure vessel 9 for combustion.  The oxygen may be preheated to not more than 600 DEG F., and the combustion is effected at pressures up to 600 lbs./sq. in. or higher.  The combustion products pass to blade section 20, where they are rapidly expanded and cooled to 500-600 DEG F., and are discharged at 25. Carbon dioxide from line 15 and/or steam from line 12 may be introduced through pipe 14 into the combustion vessel 9, and through pipe 21 before the gases pass into the blading 20, to control the temperature of the gases and the proportions of carbon monoxide and hydrogen.  The carbon dioxide and/or steam may be introduced separately from the hot gases to prevent overheating of the blades (see Fig. 2, not shown).  The carbon dioxide used may be obtained by recycling the whole or part of the carbon dioxide obtained from the catalytic conversion process to which the hydrogen-carbon monoxide gas is subjected to form hydrocarbon or oxygenated hydrocarbons. Carbon dioxide, steam, or water may be added as additional coolant at 26.  Specification 649,645 is referred to.

Filed: 1928-06-23
Abstract: 313,756. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 23, 1928. Addition to 268,599. Coking processes.-In a process of the kind described in the parent Specification in which granular materials are heated by electric resistance or arc heating while gases are forced through them to maintain them in a state of continuous agitation, gaseous and low-boiling olefines and diolefines are obtained from granular electrically conductive materials which may be carbonaceous materials. When granular coal is being treated gases such as hydrogen or vapours such as tar or oil vapours are passed through the charge. If the granular material is non-bituminous, tar or oil vapours must be used. Fire-brick impregnated with metal may be used alone when hydrocarbon vapours are treated, or a mixture of firebrick and carbonaceous material may be employed. A temperature between 500‹ C. and 900‹ C. is maintained. Tar is heated in a still D, Fig. 1, and the vapours further heated in a heat regenerator E are driven through granular coal on a grate C at such pressure that the coal is kept in agitation, the chamber A being maintained at 650‹ C. by current passed between graphite electrodes B. The vapours generated pass through the regenerator E and dust extractor G and are condensed in a vessel H from which low boiling hydrocarbons such as benzol are recovered. Brown coal is kept in agitation on a grate B, Fig. 2, by hydrogen which is blown through it from a regenerator A by a fan D. The gases generated pass away through pipe F and the regenerator A, and are treated for the recovery of olefines. The coal is charged by a screw conveyer C and the glowing coke removed by a conveyer E.
