Abstract: 353,253. Discharge apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent-Treuhand Ges. fur Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin.) July 24, 1930, No. 22315. Convention date, Aug. 30, 1929. [Class 39 (i).] In discharge apparatus such as lamps and rectifiers, of the kind provided with one or more indirectly heated electrodes each surrounded by a shell which is closed towards the discharge path and is adapted to have the tube voltage applied to it, the shell 7 is made of a sintered mixture comprising a refractory metal and one or more non- metallic substances of high electronic emissivity. To enable tubes with comparatively small electrode shells to be operated at currents of from 10-100 amperes the proportion of the refractory metal is greater than that of the non-metallic substance, for example 70-85 per cent of tungsten and 15-30 per cent of a mixture of barium oxide and calcium oxide. The shell 7 may be provided with a coating 7<1> of the same electron emitting material as that which is used in making the shell. The upper end 9 of the shell is formed similarly to the sides, but the lower end is closed by a plug 35 of insulating material such as aluminium oxide. A leading-in wire 12 is attached to the shell 7 by clamps 62 which are interconnected by wires 63, the other leading-in wire 11 being connected to the heaterelectrode 8 which extends within the shell. The conductivity of the shell may be increased by an exterior winding of a refractory wire 64 of material such as tungsten or molybdenum. Means may be provided for automatically disconnecting the heater-winding once the discharge has started. Specification 315,386 [Class 39 (i), Electric lamps, Arc &c.], is referred to.

Title: Improvements relating to methods and apparatus for degasifying fine grain fuels

IPC: C10B49/08
Filed: 1957-07-15
Abstract: 844,705. Coking. DIDIER-WERKE A.G. July 15, 1957, No. 22403/57. Class 55 (1). Granular fuel is degasified by allowing it to fall from a bunker 2 into the upper part 7 of a chamber 5 where it travels in co-current with a heating gas introduced through burners 11 so that the finer-grained fuel is degasified when it reaches an annular outlet 8. A second stream of heating gas rising from the base of the chamber 5 continues the degasification of the coarser-grained fuel, which is removed through a valve 17, the two streams of gas leaving the chamber 5 through the outlet 8, pipe 10 and blower 16 taking the finer-grained fuel with them. The gases pass through the twin cyclose chambers 21, 22, partly through pipe 28 to the burners 11, partly through pipe 29 to the burners 30 which lead to openings 13 in the lower part 12 of the chamber, and partly through cooler 32 and pipe 33 to the inlet 15 at the bottom of the tapered portion 14 of the chamber 5. The latter gases pass up through the coarse-grained fuel in portion 14 to cool it and then join the gases introduced through the openings 13. Surplus gas is removed at 35. The coarse-grained fuel is passed to a conveyer 18 and then meets the fine-grained fuel delivered from the cyclone chambers 21, 22.

Abstract: Porous membranes of cellulose acetate are prepared by precipitating a film of such solution with an aqueous non-solvent, and subsequently treating the water-bearing film with a solvent miscible with water and with a solvent organic liquid.  In an example, the acetate is dissolved in acetic acid, and the coagulent is water; such a film is impregnated with water, and for the dialysis of a benzene solution the water must first be removed by washing with alcohol, acetone, or other liquid miscible both with water and benzene.  To give greater strength to the membrane, the film may be applied to a support such as cloth.

Abstract: 1339953 Controlling converters LICENTIA PATENT-VERWALTUNGS-GmbH 19 April 1971 [19 June 1970] 22717/71 Heading H2F [Also in Division G3] A stabilized D.C. supply system of the type comprising a transformer TR and rectifier bridge GL1 feeding a load RL through a thyristor TH controlled by a pulse generator IG in response to the comparison between the D.C. output voltage and a reference voltage, is arranged to provide synchronous firing over the whole load current range by ensuring that the pulse generator can only operate when the thyristor is forward biased, that is when the rectified voltage at its anode is greater than the voltage at its cathode produced by the smoothing capacitor C3. The voltage across this capacitor is sensed by a divider R7, R8, R9 which provides a signal to the base of a transistor T1 to whose emitter is supplied a reference voltage provided by a voltage dependent resistor R1 fed from the same voltage as the divider through a resistor R6. Variations in voltage across the capacitor C3 produce corresponding variations in the voltage across transistor T1, which controls the rate of firing of pulse generator IG formed by transistors T2, T3, T4 of which T3 and T4, together with the divider R3, R4, form a flipflop circuit equivalent to the known flip-flop circuit using a four layer diode. Transistor T2 acts as a voltage controlled resistance to vary the charge rate of a capacitor C2 in accordance with the voltage across transistor T1, the drive voltage for the generator and the charging current for capacitor C2 being obtained through a diode GL2 which conducts only when the thyristor TH is forwardly biased. When the voltage across capacitor C2 reaches a predetermined value, transistors T3 and T4 become conductive to fire the thyristor TH, the subsequent immediate discharge of capacitor C2 causing transistors T3 and T4 to be cut off. Protective elements C4, R10 and GL3 are provided. Comparison is made, Fig. 2 (not shown) of the operation of a prior art stabilized D.C. supply, Fig. 1 (not shown) with that of the described embodiment expressed in simplified form, Fig. 3 (not shown).
