Electrode 11 is mounted on a wall 20 separating an adjustment chamber 2 from the arc chamber 6. The chambers 2 and 6 communicate through apertures 17 in wall, 20 The wall 20 supports one end of a spindle 22 carrying an adjustment head 23 driven by electric motor 21 to adjust the axial position of electrode 11. Arc rotating opposed field coils 12 are provided in each cylindrical electrode 10, 11. Plasma forming gas is supplied via duct 39 to the arc gap where it is directed radially, tangentially or axially to the nozzle. Subsidiary supply ducts 40 are provided in the ring segments 28 of the arc chamber. A current supply duct 15 on which current collector 26 slides supplies coolant to electrode 11, the exist duct not being shown. Coolant is passed to coils 12 by ducts 37 and to nozzle 5 by ducts 38. Coolant is also supplied from bore 34 in burner head 3 to the space between a division wall 31 and an electrode jacket 29 by which the electrode 10 is connected to terminal 14 and then flows along the passage formed between jacket 29 and coil 12 to the space between a further division wall 31 and end plate 32 before emerging from bore 35. In operation the burner 41 (Fig. 2) is connected by pressure transmitter 8, which may be a piston in a duet or as shown a compensating tank, to the closed coolant circuit. Thus the arc chamber pressure is transmitted to the coolant circuit. A monitor 43 interrupts the filling of the coolant circuit when it reaches a preselected level and stops operation as soon as the level falls below a predetermined level, e.g. on occurrence of leaks. Coolant is circulated via parallel pipes 48-53 through the movable electrode 11, the fixed electrode 10, the magnet coil 12 of the movable electrode, the magnet coil of the fixed electrode, cooling passages in ring segments 28 if provided, and nozzle 5 respectively. The coolant then flows through a heat exchanger 57, 58 and a heat exchanger 59 with fresh water supply 60 back to pump 45. Control valves 54, quantity metres 55 thermocouples 56 determine the energy given up to the coolant. The burner is used for chemical purposes and wind tunnels.
Patent GB-883040-A (GB)
Title: Recovery of glycols
Inventor: OWEN EDMUND CECIL
IPC: B01D39/04
Filed: 1959-09-14
Abstract: Finely dispersed hydrocarbon oil is removed from a crude glycol containing it by filtering the glycol through a bed of filamentary material of denier not greater than 10.  The process is particularly useful for the recovery of ethylene glycol but is also applicable to the recovery of other glycols such as 1,4-dihydroxymethylcyclohexane. The process is particularly applicable to the recovery of a glycol from the mother liquor, resulting from the alcoholysis of a highly polymeric polymethylene terephthalate in the form of fibre dressed with a spin finish containing a hydrocarbon oil but it may also be used for the purification of a glycol contaminated with a hydrocarbon oil however obtained.  Suitable filamentary materials are, for example, cotton wool, wool, polyethylene terephthalate, polypropylene and viscose fibres and when exhausted they may be regenerated by passing through a substance capable of dissolving the hydrocarbon, e.g. methanol.  The contaminated glycol may be partially purified beforehand by contacting with molten wax, by solvent extraction or by filtration through a non-filamentary material, e.g. sand, powdered glass or carbon.  Specifications 762,690 and 784,248 are referred to.

In a radiation intensity measuring apparatus a halogen-quenched Geiger-Muller tube V2 supplies impulses to the control electrode of a cold-cathode trigger tube V1 which conducts in response to the impulses, thereby discharging condensers C1, C2 which then recharge, and the charging current for the condenser C1, C2, and the current from the Geiger-Muller tube are passed through an ammeter M1 which gives a reading proportional to the sum of these currents. At first the charging current of the condensers, represented by the curve 10, Fig. 2, varies with the radiation intensity. At a definite counting rate the circuit saturates and produces a constant. output as shown by the flat part of the curve 10. At this point the current from the Geiger-Muller tube V2 becomes appreciable, as shown by the curve 11. The total current effecting the ammeter is shown by the curve 12, which gives an increased range of count indication.
