Title: Improvements in or relating to variable resistance devices
IPC: G01L9/02
Filed: 1939-08-09
Abstract: 533,038. Variable resistances. GAS LIGHT & COKE CO., and DONNELLY, R. P. Aug. 9, 1939, No. 22963. [Class 37] An apparatus for indicating pressure differences by means of relative movement between mercury and a resistance element is so arranged that this relative movement is produced by the rise and fall of a separate liquid which forms the liquid column in a manometer and balances the pressure difference to be indicated. In the construction shown, two metal cylinders a, b are connected at their lower ends by a tube c and contain a liquid e of relatively low density such as water, oil, or butyl phthalate. Pressure off-takes f1, f2 are provided. A tube g of insulating material, filled with mercury h, passes through the cylinder b and is sealed in its base by a stuffing-box j. A terminal k at its lower end makes contact with the mercury. A graphite composition rod l dips into the mercury and is supported by an annular float m and rods n. The top of the cylinder b is closed by a transparent hood o carrying a terminal p connected to the upper end of the graphite rod l by a flexible connection q. When used as a manometer the higher pressure is introduced through the outlet f1 and the lower pressure, which may be atmospheric, is admitted through the outlet f2. A glass tube t enables the level of the liquid in the cylinder b to be seen. The rod l may be the graphite core of a lead pencil and may be 0.1 inch in diameter and 9 inches in length. It may contain 72 per cent. of graphite, the remainder being refractory material such as Fuller's earth. The rod, after baking, may be impregnated with wax &c. to render it non- porous. Such a rod has a resistance of about 50 ohms per inch length. The apparatus may be used for tabular compensation in gas calorimetry, in which case the liquid b may be water. The outlet f1 is open to the atmosphere while the outlet f2 communicates with a tabular volume of air which is otherwise totally enclosed. and is maintained at the temperature of the gas as metered by a water-jacket &c. The liquid level in the cylinder b varies with the contraction or expansion of the tabular volume under the combined influence of atmospheric pressure and gas temperature, causing movement of the rod l to make the desired tabular compensation. The rod l and mercury h are connected in the recording circuit of a calorimeter which includes a differential thermopile and a recording millivoltmeter. Two graphite rods l, instead of one, may be immersed in the mercury and connections taken to their outer ends. In a modification the graphite rod l is fixed and the mercury tube g is carried by a float. The apparatus is also applicable as a flow meter by measuring the pressure difference across a Venturi constriction.

Abstract: 971,098. Dynamo-electric machines; rectifying; protective arrangements. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM). June 13, 1963 [June 18, 1962], No. 23607/63. Headings H2A, H2F and H2K. In a rotatable rectifier assembly, e.g. of a brushless dynamo-electric machine, in which the rectifiers 4 are protected by cut-out devices, e.g. fuses 5, each device is connected to the coil of a rotary magnetic inductor which co-operates with fixed detecting means. In Fig. 2, the inductor 9 has four coils 8 each connected across a fuse 5, so that when a fuse blows, the associated coil 8 is energized and the resulting rotating magnetic field induces a current in a coil 11 on a fixed core 10 to energize an alarm relay 12. Each phase or group of rectifiers may be associated with a separate inductor 9 and fixed core 10. In a further arrangement. Fig. 4, the rotatable support 15 for the rectifiers 4 and fuses 5 carries inductors 14 with coils 13, all the inductors co-operating with a single fixed core 17 and coil 18. In this arrangement a reference inductor formed by a permanent magnet (not shown) may be arranged on the same track as the inductors 14 or elsewhere. Fig. 5 (not shown) illustrates a further arrangement in which the rotating coils are arranged in slots as in a multipole field structure of a rotary machine. In both these arrangements the fixed coil 18 may energize a coincidence counter 20 which may indicate the position of a blown fuse with respect to the reference inductor and provide an alarm or luminous signal. Should more than one fuse blow, reduction or removal of the load on the rectifiers is initiated by the counter 20.

Title: Process for the production of thoriated highly emitting cathodes
Inventor: KONCZ ISTVAN
IPC: H01J9/04
Filed: 1964-06-09
Abstract: In a process for producing a thoriated cathode, a metal carbide of the composition M2C, where M is a refractory metal from the group VIA of the Periodic System, present in close-packed hexagonal form, is converted into a body-centred cubic form at elevated temperature by the presence of an element from the groups IB, VIIA or VIIIA of the Periodic System, e.g. silver, manganese, rhenium or palladium.  The invention may be applied to carburized, thoriated tungsten or molybdenum cathodes of wire or strip form, or to carburized sintered cathodes produced from thorium oxide with tungsten and/or molybdenum, for use in rectifiers, thyratons or gaseous discharge lamps.  In particular, a tungsten carbide filament may be coated with rhenium by thermal decomposition in an atmosphere of rhenium pentachloride and then subjected to diffusion heating in vacuo at 2,400 DEG K until the hexagonal form of the tungsten carbide has substantially disappeared. Alternatively, the filament may be coated with palladium by electrodeposition and then subjected to diffusion heating at 1600 DEG K.
