Title: Improvements in or relating to flame resistant regenerated cellulose sheets or filmsand to flame resisting treatment of regenerated cellulose sheets or films
IPC: D06M13/248
Filed: 1945-08-09
Abstract: A flame-resistant cellulose sheet or film comprises the incorporation in the regenerated cellulose sheet of at least 20 per cent of a salt of sulphamic acid, at least 10 per cent of a hydroxylated softening agent and at least 0.5 per cent of a formaldehyde yielding material. The salt of sulphamic acid to be used should be soluble in water at 25 DEG  C. to the extent of at least 10 per cent; the selected salt may be ammonium, an alkali or alkaline earth salt, or a salt of such amines as methylamine, dimethylamine, ethylamine, ethylene diamine. Of these the ammonium salt is preferred.  Glycerol is preferred as the softening agent, but other hydroxylated compounds such as ethylene glycol, diethylene glycol, the polyethylene glycols, hexamethylene glycol and 1,2,5-pentanetriol may be used.  As regards the formaldehyde yielding compound, formalin, paraformaldehyde, hexamethylenetetramine and partially condensed resinous products of formaldehyde with urea, melamine, urethanes, guanidines or phenols may be used.  The best results are obtained when the components are within the limits of 20-25 per cent, 15-25 per cent and 1-3 per cent respectively.  The temperature of the bath may be from 25-75 DEG  C. The invention applies to sheets impregnated while in the gel state, but it may be applied to sheets which have been previously dried out provided that they are wetted prior to impregnation.  Films and sheets so treated possess improved durability and retain their transparency under variable conditions of humidity and temperature. In an example, a gel regenerated cellulose film is produced by extruding viscose through a long narrow slit into a coagulating bath, regenerated, desulphurized, bleached and washed and then impregnated by passage through a bath of an aqueous solution containing 12.5 per cent ammonium sulphamate, 12.5 per cent glycerol and 5.4 per cent commercial formalin in water at 25 DEG  C. (parts by weight).  After thorough impregnation, excess liquid is removed by squeeze rollers and the film dried in the usual way.  The dried film is flame-resistant and is more durable than flame-resistant film made in accordance with the prior art.  Specification 515,735 is referred to.

Title: Electrical resistor and method of producing it
IPC: H01C1/032
Filed: 1963-05-23
Abstract: 995,972. Resistors. CORNING GLASS WORKS. May 23, 1963 [May 28, 1962], No. 20653/63. Drawings to Specification. Heading H1S. An electrical resistor comprises a ceramic substrate, an electro-conductive metal oxide as a primary conducting element, spaced terminal members in electrical contact with the primary conducting element, and a second metal oxide film intermediate the primary conducting element and the ceramic substrate, of relatively low conductivity compared with the primary conducting element and composed essentially of tin and antimony oxides. The term " ceramic " is used here in a generic sense to include glasses, glass-like materials, and conventional sintered ceramic materials. In one example, an essentially alkali-free, alkaline earth aluminosilicate glass cane of 0À141 inch diameter is contacted at a temperature of 650 C. with vapours from suitably proportioned solutions of the chlorides of tin and antimony. A solution of 1À00 gm. SnCl 4 .5H 2 O per 1 ml. of a solvent comprising 1 part cone. HCl and 5 parts H 2 O and a solution of 1À00 gm. SbCl 3  per 1 ml. of a similar solvent are prepared and mixed to provide a coating solution for the conducting film containing 97À75 vol. per cent SnCl 4 .SH 2 O and 2À25 vol. per cent SbCl 3 , also a coating solution for the intermediate film and a cover film containing 40 vol. per cent SnCl 4 .5H 2 O and 60 vol. per cent SbCl 3 . The thicknesses of these films are 600, 850 and 2300 A.V., respectively, and their resistances 500, 12500 and 75000 ohms, respectively. Application of terminal members on either end of the cane is followed by hermetic encapsulation of the coated cane in a glass envelope. Tests at 125 C. ambient temperature show a three-fold improvement in electrical stability compared with a similar resistance without the intermediate layer. The thickness of this layer does not appear to be critical, but should be at least several hundred A.U. to insure a continuous film. Its resistance should be such that it carries less than about 1% of the total current flow through the resistor. A slightly larger fraction, e.g. a few per cent, of the total resistor current may be carried by the intermediate film so as to provide a balanced temperature coefficient where the primary conducting element has a positive temperature coefficient but this will usually have an adverse effect on stability and may be utilized only where such an effect may be tolerated. Specifications 639,561, 806,189 and 806,190 are referred to.

Abstract: 379,476. Gas meters. TENNANT, W. J., 111, Hatton Garden, London.- (Brandl & Co., Commanditges.; 6, Wiedner Gurtel, Vienna.) July 23, 1931, No. 21100. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 23, 1931.] [Class 54.] The measuring element of a gas meter operates the counting mechanism through a system of levers and connecting- rods, one or more articulation points of which are movable under the control of a thermometer, manometer, or barometer so as to produce readings corrected for variations in gas temperature, pressure or barometric height. Fig. 1 shows a crank pin 1 rotated by the measuring element connected by a rod 3 to a bell-crank lever arm 4, a second arm 6 of which is connected by rods 7, 9 to a rod 10 reciprocating in guides. The rod 10 is connected by a rod 11 to an arm 12 carrying a pawl 14 operating the disc 15 of a counting mechanism. The pivot 8 between the rods 7, 9 is carried by a rod 16 pivoted to an arm 17 which is rocked about its pivot 18 by a manometer 22 acting through a rack 20 and toothed segment 19. The displacement of the pivot 8 by variations in the gas pressure effects the compensation necessary in the transmission system 3, 4, 6, 7, 9, 10, 11, 12 to correct the meter reading. To prevent the transmission system from affecting the manometer 22 the adjustment of the pivot point 8 is preferably effected only when the crank is at a dead centre. For this purpose the lever 17 is formed with a segment 33 which is normally held stationary by a brake block 35 on a spring- pressed lever 34, and the bell-crank lever 4, 6 is formed with an arm 37 which at one deadcentre position engages the lever 34 to remove the brake block from the segment. Fig. 2 shows a modification in which the rack 20 is pivoted to a lever having one arm 24 operated by a manometer 22 and the other arm 25 linked to a lever having one arm 29 operated by a thermometer 31 and the other arm 30 operated by a barometer 32.
