Title: Apparatus suitable for monitoring sodium vapour content of a gas
IPC: G01N27/416
Filed: 1973-09-28
Abstract: 1415416 Electro-chemical analysis WESTINGHOUSE ELECTRIC CORP 28 Sept 1973 [6 Oct 1972] 45427/73 Heading G1N Sodium vapour pressure is monitored using a solid electrolyte exhibiting significant sodium ion conductivity. The electrolyte may be fabricated from glass, molten salts (NaCl, NaOH) impregnated in a disc, sodium beta-alumina (Na 2 O-11 Al 2 O 3 ) or sodium double beta alumina Na 2 O- 5Al 2 O 3 -MgO. The solid electrolyte disc 12 is mounted in a gaseous environment G which may be an inert gas surrounding sodium containing pipes of a sodium cooled fast breeder reactor, Fig. 3 (not shown). Porous electrodes 14, 16 of molybdenum, nickel or stainless steel are mounted on opposite surfaces of the electrolyte and suitably biased by battery V. When sodium atoms impinge on anode 14 they are converted into sodium ions which are conducted across the electrolyte to the cathode 16 generating a current which is monitored by ammeter A and which is a direct measure of sodium vapour pressure at a given voltage and temperature (maintained by heater 26). If the vapour pressure is sufficiently high the current saturates and under these conditions the device may operate in a yes/no manner. The device may be operated in a voltage mode whereby the electrodes are isolated from one another and a known sodium vapour pressure is established at one of the electrodes and the unknown at the other electrode. The resultant generated e.m.f. is measured by a voltmeter connected across the electrodes, Fig. 4 (not shown) and is indicative of the difference in vapour pressures. The device may be used to measure temperature by keeping the vapour pressures at a known value.

Abstract: 1,011,887. Feeding record tapes; controlling tension. W. STUDER. Dec. 20, 1961 [Dec. 20, 1960], No. 45725/61. Heading G5R. [Also in Division G3]. The feed reel of a tape record/playback apparatus is braked by a reverse-torque motor 11 controlled by reel speed-sensing means so as to maintain constant tape tension. A photo-electric tachometer 14-16 produces an output which is fed to a frequency-sensitive filter 16c, 16d and after amplification at 17 and rectification at 18, control current is fed to a saturable reactor 21 which controls the braking current supplied to the motor 11. In an alternative embodiment (Fig. 4, not shown), the photo-electric tachometer is replaced by a ferrite disc and head arrangement. The control being derived from the reel speed takes account of the change in tape-coil diameter as winding proceeds.

The periodic focusing system of a travelling wave tube has a portion of modified construction at the collector end, to provide a change in the pass band structure of the system, such that the electron beam is transmitted in the first pass band of the first portion of the system, but at the lower edge of the second pass band of the second portion, whereby in the second portion slow electrons which would otherwise extract energy from the signal wave, are defocused and collected on the slow wave structure. The final few periods of the second portion may exhibit a further change of periodicity or of peak field strength, to improve the focusing of the transmitted fast electrons.

Title: Treatment of molten metal
IPC: F27D27/00
Filed: 1962-12-13
Abstract: In a method of agitating molten metal its container is given a reciprocating tilting motion of invariant frequency but variable amplitude. As shown in Fig. 3 the container 1 is a converter oscillated on trunnions 33 by a variable throw crank comprising a disc 11 revolving at constant speed and carrying a screwed spindle 15 on which is a nut 16 linked to the converter by a connecting rod 17, 18, the throw of the crank may be adjusted from zero when the nut 16 is at the centre of the disc to a maximum. <PICT:0980941/C6-C7/1> A spring connection 19 may be incorporated in the connecting rod. The converter may be elliptical in cross-section and arranged to tilt about an axis normal to its major diameter; the reciprocating tilting motion may take place about a different axis in which case the converter is suspended from gimbals in a carrier ring. Preferably the converter has an elliptical cross-section in which the ratio of the minor to the major diameters is 1:1.2 to 1:1.5; the plane of reciprocatory tilting motion should then be inclined to those of the orthogonal axes of symmetry and its axis should pass through the centre of gravity of the converter.  A circular motion of the bath is thus generated, the frequency of reciprocation being chosen to be in resonance with it.  In other embodiments the reciprocating motion may be provided by a double acting piston and a rocking lever the fulcrum of which is movable from the centre of the lever to a point opposite the connecting rod pivot, see Fig. 1 (not shown) or by a solenoid 22, Fig. 4, having a core connected to the converter by a rod 18 and controlled by a spring 19; the reciprocating motion is obtained by exciting the solenoid with a pulsed or alternating current and the amplitude varied by shifting the coil.  The spring 19 may be replaced by a second solenoid, see Fig. 5 (not shown); the amplitude may be varied by dividing the solenoid coils into several separately excited pairs, see Fig. 6 (not shown).
