Patent GB-708909-A (GB)
Title: Improvements in or relating to the production of artificial filaments, films, tubes and the like
IPC: D01F2/28
Filed: 1950-09-13
Abstract: Filaments, films, or tubes, are obtained by dissolving a cellulosic hydrophilic colloid in an aqueous medium, forming the solution into the appropriate shape by extruding under pressure through an appropriately shaped orifice, or by casting by spreading, and passing the formed articles into a coagulating bath comprising an aqueous solution having a phosphate content and an alkali metal content corresponding or equal to the composition of an aqueous solution containing at least 10 per cent. of orthophosphoric acid and at least 25 per cent. of mono-sodium di-hydrogen ortho-phosphate.  The cellulosic solution may be an alkaline solution of a cellulose ether such as an alkali-soluble hydroxyalkyl cellulose ether, an alkaline solution of a degraded cellulose, an alkaline solution of a cellulose ether-xanthate, a solution of cellulose xanthate, or a cuprammonium cellulose solution.  If an acidic spinning solution is used, the composition of the coagulating bath should be such that it has an alkaline reaction.  The coagulating bath may be saturated with the alkali metal phosphate.  It may be formed by mixing phosphoric acid and sodium hydroxide solutions so that the mixture contains the equivalent of 30.4 to 47.8 per cent. of H3PO4 and 8.3 to 27 per cent. of caustic soda.  At temperatures above 25 DEG  C., more concentrated solutions may be used.  In an example, a solution of hydroxyethyl cellulose in dilute caustic soda is extruded into a coagulating liquid containing the equivalent of 36 per cent. H3PO4 and 17 per cent. NAOH and formed into a film, tube, filament, or bundle of filaments.  In another example, the coagulating bath contains the equivalent of 37 per cent. H3PO4 and 20 per cent. NaOH.  The surface of the film obtained is covered with a crystalline or frosted design. Filaments of subdued lustre are also obtained.  In another example, the coagulating bath contains 15 per cent. of H3PO4 and 30 per cent. of NaH2PO4. Instead of hydroxyethyl cellulose solution there may be used a solution of sodium carboxymethyl cellulose.

Title: Improvements in or relating to electronic counting circuits
Inventor: BAKER GEORGE THOMAS
IPC: H03K23/82
Filed: 1948-08-26
Abstract: 656,624. Counting-apparatus. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Aug. 26, 1948, No. 22559. [Class 106 (i)] An electronic counter which delivers a signal at a preset count, and comprising a scale of two counter V driving a cyclic counter V1, V2, V3, has switching devices S1 and S2 between the scale of two counter and cyclic counter, and between the cyclic counter and output whereby the count can be preset. The counter shown can be preset for counts up to 12, and S1 and S2 comprise ganged 12-point switches. The scale of two counter V comprises a toggle-connected double-triode and the input pulses are fed to its cathode. The cyclic counter comprises three double-triodes arranged as described in Specification 632,411. Successive contacts of S1 are connected to either anode A1, A2 alternately of V, whilst the wiper is connected to the common cathode input of the cyclic counter. Successive pairs of contacts of S2 are connected to the six anodes in sequence of the cyclic counter and the wiper of S2 to the output OP. The cyclic counter itself counts only up to six, dependent upon the setting of S2, but odd or even input pulses only, depending on the setting of S1, are passed to it by V. Consequently input pulse counts up to twelve can be preset by adjustment of S1 and S2 together, S1 interpolating the paired steps of S2. This maximum number can be readily reduced to ten by bridging terminals T1 and T2 connected respectively to the lower grid of V3 and the upper anode of V2. A key RK is provided for momentarily interrupting the negative voltage to the lower grids of all four valves in order to zeroize the apparatus. This would be done automatically by the output pulse when successive counts are required to follow automatically, as in counting pills or other small articles into containers.

Abstract: 635,690. Detectors. GENERAL ELECTRIC CO., Ltd., BRITTAIN, F. H., and JAMES, E. G. July 31, 1946, No. 22884. [Class 40 (v)] A crystal rectifier consists of a capsule containing a crystal attached to a low inductance support and a metal whisker consisting of a short spike projecting from a metal body of low inductance, the required resilience between the whisker and the crystal being provided by the resilience of the supports for the crystal and/or the whisker. The Figure shows a silicon crystal 4 supported by a nickel-iron alloy rod 2 which is held in position within a copper tube 1 by a ceramic bead 3. A tungsten wire 6 is welded to the vertex of a tripod 8 of beryllium copper alloy, which is fixed to a copper nickel cup 9. The components may be coated with a layer of butyl-methacrylate cement and then baked at 100‹ C. so that they are retained in position. This cement may be used to provide a meniscus round the point of spike 6 to prevent lateral movement over crystal 4. The required resilience between spike 6 and crystal 4 is provided by the tripod member 8. A cup 13 may be used to seal the end of the tube 1. The resilient tripod member 8 may be replaced by other resilient forms such as a U-shaped member, and alternatively the crystal, instead of the whisker, may be mounted on the resilient member. The arrangement provides a low inductance form of whisker. Instead of being pointed, the end face of the whisker may be flat, the crystal being inclined so that contact is made by the edge of the face, which enables a shorter spike to be used.
