Title: Improvements in or relating to circuit arrangements for generating electrical waveforms
IPC: H03H7/32
Filed: 1942-06-17
Abstract: 574,133. Impedance networks. BLUMLEIN, D. (Representative of Blumlein, A. D.). June 17, 1942, Nos. 8337, 10213, and 10214. [Classes 40 (iii) and 40 (v)] A stepped wave or an impulse is fed to the ordinary input terminals of a properly terminated delay network and the voltage resulting across the series elements is utilized as shown in Fig. 1. Alternatively, the current in all the shunt elements may pass through the output circuit. In a modification of the latter system, Fig. 3, the network has a double termination and the shunt elements are split. By making the sections of suitable sizes a response corresponding to a desired kind of filter network can be obtained by a method analogous to that described in Specification 517,516. The output may include a component obtained from' the potential drop in the terminating resistance. The input and output circuits may be interchanged. The networks may be used for generating impulses, for example a stepped wave may be applied to a network like that in Fig. 1 in which the series elements on the side from which the output is taken increase and then decrease, the characteristic impedance remaining constant by the provision of a corresponding decrease and then increase of the elements on the other side. An impulse as shown in Fig. 5 is then produced. Impulses with negative portions may be obtained by means of inductive couplings with the series elements or by combining the outputs of two networks to which the input is fed in opposite phase. In another group of arrangements for generating impulses, the sections are uniform but the delay network is misterminated so that voltage impulses produced by interference between the original wave and the reflected wave are obtained at output terminal connected across series elements of a delay network or current impulses are obtained in a load connected at 9, 10, Fig. 8, through which the currents in all the shunt elements flow. With the shunt elements connected to both sides of the output circuit, impulses with positive and negative portions are produced. Another arrangement, Fig. 6, produces a voltage impulse as shown in Fig. 7 at terminals 9, 10.

IPC: F16K15/20
Filed: 1965-02-26
Abstract: 1,058,324. Valves. INSTRUMENT RESEARCH LABORATORIES Ltd. Dec. 21, 1965 [Feb. 26, 1965], No. 8348/65. Heading F2V. An inflator valve for life-rafts and the like comprises a housing 12 with an integral tapered flange 11 for attachment to the raft fabric 27, the housing being closed by an anchor plate 15. Plate 15 has a central aperture 16 and a concentric ring of openings 17. Mushroom-shaped closure member 18 has a stem 21 extending through the opening 16 and surrounded by soft rubber tubing 23 to hold both a shoulder 19 and the periphery 20 of the closure head in contact with plate 15. The stem 21 may be pulled through the plate 15 by means of an extension 24, which is subsequently cut off. A captive plug 29 excludes foreign matter from the valve. All the parts, except the plate 15, may be made of resilient synthetic plastics material or rubber. The plate 15 may be metal or rigid synthetic plastics. Grooves 26 in the housing 12 help to make a gas-tight seal with an inserted inflation pump by which air is forced in through openings 17. To hold th fabric 27 away from the valve openings, spacer pads 28 are formed during moulding of the member 11, 12. In a modification, the rubber tubing 23 is replaced by a conical spring (40). The raft may be deflated by pushing the prongs of a U-shaped tool through the openings 17 to force the closure member off its seating. This tool may be plastics-coated brass wire housed, when not in use, in the closure plug.

Patent GB-804301-A (GB)
Title: Improvements relating to metal-coated fibres
IPC: C03C25/46
Filed: 1955-03-24
Abstract: A process of treating metal-coated glass fibres comprises applying to the metal coating a reagent which reacts therewith and modifies the surface, and applying a lubricant to the modified surface.  The metals include lead, tin, zinc, copper, aluminium, magnesium, cadmium, iron, and silver, and the following alloys are mentioned: Wood's alloy, Rose's alloy, zinc-cadmium, zinc-lead, zinc - titanium, lead - copper, lead - tin, aluminium - copper, aluminium - gold, aluminium - zinc, aluminium - tin, lead-antimony, copper-cadmium, tin-indium, silver - tin, silver - zinc, antimony - zinc, copper - zinc, antimony - tin, copper - aluminium, Dow metal and mixtures of any of these alloys.  The lubricant, which may be mercury, an oil, a metal film, or an inorganic or organic material, provides a means of holding individual fibres together during grouping into a strand without adhesion of adjacent fibres, and may be applied before or after grouping.  In one example, glass fibres coated with Mg, Cd, Zn, Cu, Fe or Al are exposed to air saturated with water vapour to provide an oxide film and a 1 per cent solution of lauric acid in paraffin oil applied to form a metal soap as lubricant.  In other examples, glass fibres coated with cadmium or copper are exposed to chlorine to form a chloride layer and then covered in paraffin oil, or the metal-coated fibres may be covered with paraffin oil after treating with ammonium polysulphide or sodium sulphide solution to form a sulphide layer on the metal.  In further examples, the metal-coated glass fibres are treated with acids or bases, e.g. chromium-coated glass fibres may be etched with sulphuric acid and a coating of a mineral oil lubricant applied, or, after etching, a coating of a hard metal, e.g. chromium, may be applied as lubricant. Specification 738,869 is referred to.

Title: Improvements in or relating to zone refining of metals
IPC: C30B13/06
Filed: 1956-03-20
Abstract: <PICT:0818179/III/1> <PICT:0818179/III/2> <PICT:0818179/III/3> <PICT:0818179/III/4> In the zone-melting refining of a body of metal or of silicon, part at least of the exterior of the body at the molten cross-section is kept below its melting-point so as to confine the molten zone, the zone moving to refine the interior of the body. Fig. 1 shows a bar 10 being passed between electrical contact rollers 12 and 14, sufficient current being passed to melt a zone 20 while the exterior of the bar is kept solid by radiation loss, cooling gas jets, or by water-cooling the rollers; impurities are carried to the end at 28 when the current is switched off and the zone solidifies. Two spaced pairs of contact rollers may be used so that the molten zone is set up between them and is not subjected to pressure.  Fig. 4 shows a bar 50 carrying a longitudinal electric heating current supplied by water-cooled terminals 52 and 56, the current being insufficient to set up a molten zone except at 66 where an encircling ring 64 of thermal insulation is provided, the ring being moved by worm 70; alternatively, the ring 64 may include additional heating means such as an electrical resistance or induction heater.  Instead of being of circular cross-section, the metal body may have a section such as that shown in Fig. 6 or Fig. 7, that part inside a circle of radius 106 being melted and parts 96 or 108 remaining solid to form an enclosing cage for the molten metal.  A number of induction coils may be arranged to move in succession along the body, and set up zones of successively smaller cross-section so that each zone after the first sweeps through and further refines only already purified metal; in the case of the apparatus of Figs. 1 and 4 a similar method is to effect zone-passes at successively lower heating currents. After the zone-refining process is completed, the unrefined parts of the metal bar may be removed by machining; an atmosphere such as helium, or a selected non-oxidizing atmosphere capable of producing a desired reaction product, may be used.  Reference has been directed by the Comptroller to Specifications 769,673 and 775,986.
