Abstract: 665,630. Electric indicating systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 17, 1950. [Feb. 17, 1949] No. 4406/49. Class 40 (i). [Also in Group XXXVI] In capacity measurement, a capacitance pick-up 13 e.g. for measuring turbine blade clearances is connected through coaxial cable 14 to an inductor 11a of a coupling device, which is shunted by a variable capacitance 11b and inductively coupled to an inductor 11c which is connected through coaxial cable 15 to the input of an A.C. resistance bridge 12 operating at 50 Kc/s. The pick-up, the stray and variable capacitances, and the coupled inductors constitute a parallel resonant circuit which is tuned by the variable capacitance to the bridge frequency, for minimum pick-up capacity. A resistive impedance is reflected to the bridge input, and varies with small changes in pick-up capacity, so that the bridge may be calibrated to indicate the latter, or e.g. the blade clearance.

Abstract: 607,986. Batteries. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., WEBBER, N. W. D., and SHEPPARD, E. A. Feb. 13, 1946, No. 4507. [Class 53] [Also in Group XVIII] In an apparatus for automatically maintaining constant the level of liquid in a battery, reservoir 2, sealed at its upper end has intermediate reservoir 3 supplied with liquid through pipe 4. Supply pipe 5 has its upper end approximately level with the liquid in reservoir 3, and control pipe 6 has one end approximately level with the liquid in reservoir 3, and control pipe 6 has one end approximately level with the liquid in battery 1, the other end above the liquid in reservoir 2.

Abstract: 687,566. Conveyers. NYBORG, T. G. and MINING ENGINEERING CO., Ltd., March 2, 1950. No. 4585/49. Class 78 (i). A conveyer is moved laterally step-by-step over a floor by a plurality of devices spaced along one side of the conveyer framework and operated simultaneously, each device comprising an arm pivotally connected to the framework and to a foot normally resting on the floor and arranged so that operative movement of the arms lifts the side of the conveyer framework to which they are attached and moves the whole framework laterally with its opposite side supported by the floor, whereafter the arms and feet are returned to their original position relative to the framework and the conveyer drops to its new position flat on the floor As shown the conveyer framework is provided at intervals with arms 14 pivoted at 16 and carrying feet 17 on pivots 18. To advance the conveyer sideways, compressed air is supplied through pipes 8 to cylinders 9 so as to force downwardly pistons 1 1 connected by links 12 to the arms 14, thereby rotating these latter arms clockwise and lifting the framework to the position shown in Fig. 3 and at the same time moving the framework sideways a distance "A".

Filed: 1928-02-14
Abstract: 311,796. International General Electric Co., Inc., and Mayo, C. G. Feb. 14, 1928. Addition to 224,873. Transformers. - In an arrangement for measuring the voltage on the high-pressure side of a power transformer from the low-pressure side as claimed in the parent Specification, a reactor is employed which is supplied directly from the high or low pressure side of the power transformer. This is equivalent to combining the reactor and current transformer of the parent Specification in one unit. To the low-pressure side of the power transformer A is connected the potential transformer B supplying the measuring-instrument C. In order to compensate for the reactance of the transformer A under varying load, a reactor D is connected in the circuit of the instrument C. The core E of the reactor is provided with an air-gap F allowing the reactor to be positioned around one of the power transformer leads either, as shown, on the low-pressure side or on the high-pressure side. The reactor thus functions as a current transformer. The invention may be applied to polyphase circuits.
Patent GB-610703-A (GB)
Title: Improvements in the processing of hydrocarbons
IPC: C07C5/27
Filed: 1941-04-07
Abstract: Normal paraffins are converted to branch chain hydrocarbons by passing over an aluminium halide, with or without an activator such as water or hydrogen halide, in the presence of a normally volatile mercaptan of the formula RSH, where R is an alkyl radical, in an amount corresponding to not more than 5 per cent sulphur by weight of the normal paraffins.  Liquid or vapour phase, batch or continuous operation may be used.  Preferably, the hydrocarbon vapours, mercaptan and activator are passed over the catalyst, for example on a porous carrier, the product being fractionated, and unconverted reactants recycled.  Temperatures up to 300 DEG , generally 50-200 DEG  C., and pressures up to 100 atm. may be used.  An example gives comparable figures for isomerization of butane with aluminium chloride and hydrogen chloride, at 123 DEG  C. and atmospheric pressure, alone and containing .4 per cent ethyl mercaptan.  The Provisional Specification comprises the use of volatile sulphur compounds of the formula <FORM:0610703/IV(b)/1> , where R1 and R2 are hydrogen or alkyl radicals.

Title: Electron gun structure for concentrating an electron beam utilizing simultaneously electric and magnetic fields
IPC: A01K31/07

Abstract: 855,373. Travelling-wave tubes. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Feb. 13, 1958 [Feb. 13, 1957], No. 4785/58. Class 39(1). An electron gun for producing a beam with parallel edges, e.g. in a travelling-wave tube, in which the cathode is immersed in a magnetic focusing field, the cathode emissive surface is mounted in or formed by a cavity in a ferromagnetic element and the emissive surface conforms with an equipotential surface of the magnetic induction so that the initial electron trajectories coincide with the field lines. The cavity is constituted by a soft magnetic material and its internal diameter increases in the direction of electron flow. In Fig. 1 the cathode surface 1 is spherical and conforms approximately with a hyperboloidal equipotential surface 4 set up by the conical pole piece 2. In Fig. 2 the cathode body 17 is itself ferromagnetic and is surrounded by an annular ferromagnetic member 18 whose concave spherical surface 19 follows that of the cathode. A conical member 24 secured to the member 18 constitutes a focussing electrode of Pierce type, or the member 18 may be conical instead of concave. The cathode 17 may be formed of a ferromagnetic material which has a relatively high Curie point, e.g. cobalt or an alloy containing iron and cobalt, e.g. in equal parts. The concave surface is coated with a layer of sintered nickel powder or sheet nickel which serves as a base for the emissive layer. For generating a flat beam a cathode with a cylindrical emissive surface is used, and the surrounding ferromagnetic members are two prismatic elements.
