Title: Improvements in or relating to radio antennae
IPC: H01Q9/26
Filed: 1939-06-22
Abstract: 530,406. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 22, 1939, No. 18250. Convention date, July 28, 1938. [Class 40 (v)] A directive aerial with a wide band characteristic, suitable for transmitting or receiving television signals, consists of a multiple-V arrangement, the various elements being effectively in parallel though the wires may be connected in series, each leg of each V consisting of a pair of closely-set wires. As shown in Fig. 3, each. of the legs A, B is an odd number of eighths of the working wavelength. In Fig. 5 the length of the legs is the same, though the inside pair B, B includes a surge impedance at the apex ; this gives a particularly wide band characteristic. In Fig. 4 the legs are each an integral number of half-waves in length, and the inside pair are open-ended. The wires may be of different diameters. Owing to the close spacing of the wires, the radiation characteristic is equivalent to that of a single dipole though the radiation resistance is quadrupled. This means, in practice, that no impedance-matching coupling is required between the aerial system and the feedline TL. Specification 500,162 is referred to.

Abstract: 404,034. Inductances. BARON, H., 231, Strand, London.-(Fitzgerald, A. S. ; 433, Warwick Road, Wynnewood, Pennsylvania, U.S.A.) July 1, 1932, Nos. 18782/33, (divided on 407,014, [Group XXXV], and 34292/32. [Class 37.] Relates to a magnetic amplifier comprising a number of units 10-40 in cascade, each unit comprising an iron core with a D.C. control winding and a winding supplied with A.C., controlled by the D.C. winding, and connected by a rectifier to the D.C. winding of the succeeding unit. Each core has a divided central leg with an A.C. winding 13-43 on each portion and a D.C. control winding 15-45 wound on the centre leg as a whole, which leg also carries opposed D.C. windings 15-45 for neutralizing the effect of the normal D.C. flowing in the control windings. The A.C. flow depends on the amount of saturation of the divided central leg portions. For maximum amplification, the A.C. magnetic circuit should be of relatively small dimensions, i.e. easily saturated, and the D.C. circuit and winding relatively large, which on the other hand, for large outputs the A.C. magnetic circuit should be of ample proportions. The units may be of similar design at each stage, e.g. similar to unit 10, but of increasing overall size, or, as shown, the overall size is the same for all units but the A.C. portion is of increasing size, the latter arrangement sacrificing some amplification in the later stages. The cores, particularly of early stages, may be of high permeability alloy such as described in Specification 188,688, [Class 37, Electricity, Measuring &c.], silicon steel being used for later stages if desired.

Patent GB-794518-A (GB)
Title: Metallic halides
Inventor: WAINER EUGENE
IPC: C01G1/06
Filed: 1955-06-30
Abstract: Halides of tantalum, lower valent halides of titanium, niobium and vanadium and tetrahalides of zirconium and hafnium are prepared by reacting at 700-1100 DEG  C. in a bath of fused alkali and/or alkaline earth metal halide, a carbide or a carbide/monoxide solid solution of the desired refractory metal and fluorine, bromine, carbonyl bromide or iodine.  The nature of the product with metals having more than one halide is determined by the temperature: with titanium, 700-900 DEG  C. favours trivalent halides, 900-1100 DEG  C. dihalides; with niobium, 700-900 DEG  C. favours tetrahalides, 900-1100 DEG  C. dihalides; with vanadium, 750-850 DEG  C. favours trihalides, 850-1000 DEG  C. dihalides; with tantalum, pentahalides are formed throughout the temperature range.  These halides will generally be present in the bath combined as double or complex halides, although if an alkaline earth metal halide other than fluoride is present together with a double fluoride there is a tendency to evolve the halide (other than fluoride) of the refractory metal.  The melt may be fractionally distilled to recover the various constituents or (for trihalides) cooled and then fractionally crystallized from an aqueous acid solution; dihalides are preferably used in the form of the fused salt solution.  Specified fused bath components are the fluorides, chlorides, bromides and iodides of lithium, sodium, potassium, calcium, barium, strontium and magnesium and in addition refractory metal halides, e.g. alkali metal double halides, may be present before passage of the halogen into the bath. The halide present initially in the fused bath is preferably the same as that of the halide being prepared.  The reaction should take place in an oxygen- and moisture-free atmosphere, e.g. of argon; the reaction vessel-e.g. of graphite-may be externally heated or the reactants may be heated by electrical elements, to a temperature 50 DEG  C., preferably 100 DEG  C., above the melting point of the salts.  The carbide used in the reaction may be of ordinary dense form but is preferably of the less dense form described in Specification 788,296, and may be in large or small lumps or as powder.  Adequate mixing is provided by bubbling in the halogenating gas.  The reacted mass may be filtered under an inert atmosphere through porous graphite to remove carbon or the latter may be skimmed off.  In examples: (1) 40 per cent KTiF4 is produced using titanium carbide and fluorine at 875 DEG  C., and (2) 26 per cent KTiF3 is produced under the same conditions.

Abstract: 672,170. Indicating rate of fluid flow. AMERICAN VISCOSE CORPORATION. July 31, 1950 [Sept. 22, 1949], No. 19051/50. Class 97 (ii). Apparatus for controlling and indicating the rate of flow of a liquid stream, e.g. of coagulating liquids, as they proceed to the coagulating bath receptacle in artificial filament spinning machines, comprises an open-topped chamber 2 having in the bottom 3 a supply conduit 11 communicating . with a removable device 12 with a central channel constituted by a calibrated orifice portion 13 of uniform circular cross-section for regulating the liquid flow therethrough to a predetermined constant flow under a constant head, and a tapered portion 14 uniformly increasing in circular cross-section from portion 13 to the discharge passageway 15 of uniform circular section. The device 12 is centrally mounted in the stopper-like member 16 of resilient material such as rubber disposed in the bore of boss 10 on the bottom 3. The liquid under the head passes out from the passageway 15 in a trajectory inclined from the vertical to hit the wall 6 on which may be fixed a scale or indicia 24 to measure the height of the trajectory which is an indication of the velocity of the liquid stream through the orifice 13 and consequently a measure of the rate of flow of the liquid through the apparatus. A baffle directs the liquid falling from the trajectory to the outlet 28 of the chamber. An alternative form of regulating orifice consists of a stopper adapted to be screwed into the boss 10 and has a circular uniform bore with an orifice member, e.g. of glass, pressed or otherwise secured into a recess in its inner end.
