Patent GB-838743-A (GB)
Title: Improvements in or relating to processes for the production of graphite bodies
Filed: 1958-01-20
Abstract: Graphite bodies are produced by graphitizing shaped bodies comprising pitch coke with pitch as binder, wherein the pitch coke is produced from a coal-tar pitch which is substantially free of constituents which are non-liquefiable in the process, such as high molecular weight oxygen, sulphur, or nitrogen compounds, the coal tar pitch being coked by thermal decomposition in the liquid phase, the gaseous constituents of the pitch which are separated therefrom being removed without the pitch passing through the gaseous stage, and the pitch being slowly heated up to a temperature of 600 DEG  C.  The non-liquefiable constituents may be separated by melting and centrifuging, the pitch being mixed with anthracene oil if it is desired to reduce the viscosity of the melt.  Alternatively the pitch may be dissolved in benzene, toluene, chlorobenzene, dichlorobenzene, anthracene oil, pyridine or quinoline, the insoluble constituents being removed by filtering, settling or centrifuging.  The pitch is held at a temperature in the range 340 DEG  to 400 DEG  C. for at least three hours to produce nuclei around which the coke can form when the temperature is raised.  The nucleus formation period is preferably carried out under high pressure and normal or reduced pressure is employed for the coking step.  The coking chambers employed should be free of heavy metals or heavy metallic oxides and partitions are arranged within the coking chambers or concentric vessels arranged within the normal coking vessels, the inner part being charged with the pitch free of non-liquefiable constituents and the outer part being charged with normal pitch or pitch enriched with the discarded non-liquefiable constituents, so that the latter is in contact with the heating walls and in a rapid coking process produces poorlygraphitizing coke whereas the central pitch cokes slowly and produces the coke which graphitizes well. Coking may proceed beneath a column of liquid pitch.  The pitch coke produced may be admixed with calcined coke, semi-coke or low-sulphur petroleum coke or may be used alone, in admixture with coal tar pitch, free of non-liquefiable constituents, to form moulded bodies which are graphitized at temperatures below 2,650 DEG  C.

Abstract: 817,341. Ball mills. MITCHELL ENGINEERING Ltd; April 20, 1956 [Jan. 21, 1955], No. 1937/55. Class 59 [Also in Group XXVI] A ball-tube type of grinding mill comprises fixed feed and discharge boxes 24, 25 for introducing air or other gas and material to be pulverized into the mill and for discharging pulverized material from the mill, and sealing rings 31, each including a labyrinth seal, adjacent to the clearances between the fixed and rotating parts of the mill, means being provided for supplying air or other gas to the sealing rings to pass through the clearances into the mill to prevent egress of pulverized material through the clearances. The drum 1 has secured thereto head castings 4 each comprising a frusto-conical wall 5 supported by spokes 6 from a boss 7. The boxes 24, 25 each comprise a cylindrical part 26 fitting, with sufficient clearance to allow rotation of the mill, within a bore 27 formed in the frusto-conical wall 5. Each sealing ring 31, which is formed in two semi-circular halves, Fig. 5, which are clamped on to the cylindrical part 26 by means of bolts 30, encloses an annular chamber 32 to which air or other gas is supplied through a conduit 34. The end face of each frusto-conical wall 5 is formed with grooves 35 into which fit projections 36 formed on the sealing ring to form a labyrinth seal. To allow for thermal elongation of the drum 1 during operation, the projections 36 at the discharge end of the mill, Fig. 3, extend only partly towards the bottoms of the grooves 35 when the mill is cold. The bottom of each chamber 32 is provided with a pipe 40 leading to a trap 41 for material which may have entered the seal from the grinding chamber. Material is fed to the box 24 from a source 21, Fig. 1, by means of a motor-driven table feeder 16. The cylindrical shell 14 of the mill has bolted thereto, with the interposition of cork or like insulation, corrugated liners 15.

Title: Improvements relating to the control of low-speed induction motors
IPC: H02P5/74
Filed: 1952-01-28
Abstract: 700,894. Control of A.C. motors. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. Jan. 28, 1952 [Feb. 12, 1951], No. 2247/52. Class 38(3) An induction motor has two stator windings S, S<SP>1</SP>, of different pole number, two groups of rotor windings R, R\ and starting resistances r, r<SP>1</SP>, the winding S corresponding to the higher speed operation. When the low speed winding S<SP>1</SP> alone is excited, slip-rings b carry no current so that the windings R, R<SP>1</SP>, operate in series. The two groups of rotor windings act in parallel when only the winding S is in use. The change-over from one speed to another is performed without interrupting the motor torque. The motor is operated at low speeds in driving and braking by exciting one of the stator windings with direct-current, preferably the winding S, whilst the other stator winding is connected to the alternating-current supply. The resultant low speed is varied by adjustment of the starting resistance and the excitation of the stator windings. For braking, the high-speed winding may be excited with direct-current and the lowspeed winding de-energized.
