Abstract: 926,605. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 19, 1962 [March 24, 1961], No. 10854/61. Class 39 (4). [Also in Group XXXVI] Fire detection apparatus in a gas-cooled nuclear reactor comprises two pairs of spaced electrodes between which a gas is arranged to pass, means for applying between one pair of electrodes an electric field sufficient to collect both " large " ions (i.e. Charged condensation nuclei) and " small " ions (i.e. those produced by ionizing radiations), and between the other pair an electric field sufficiently low to collect only " small " ions, the two currents from the pairs of electrodes being subtracted to give a current substantially dependent only on the number of " large " ions in the gas. The electrodes may be arranged as pairs of concentric cylinders, or as three concentric cylinders through which the gas passes, first through the inner space then through the outer or through both in parallel. Suitable electrode potentials are 20 volts and 1000 volts. A common connection may be taken from one electrode of each pair to a vibrating reed electrometer.

Filed: 1937-04-20
Abstract: 475,086. Preventing fires. POLLARD & CO., Ltd., E., and POLLARD, H. E. April 20, 1937, No. 11301. [Class 47 (ii)] In a closing arrangement for counterbalanced fireproof shutters of the kind in which the fusion of a link releases a weight which normally is held clear of the shutter, the weight A is held in its raised position by means of a pivoted arm F, the lower end of which is latched by a slide member K. The member K is held by a fusible link D, and is adapted to be moved, to release the arm F, by a spring H. Travel of the weight is controlled by adjustable stops S. The impulse given to the shutter by the falling weight can be controlled by lengthening or shortening rods C, which, when the weight is released, engage the bottom bar of the shutter.

Title: Improvements relating to electrode assemblies for electron discharge tubes
IPC: H01J21/36
Filed: 1955-04-19
Abstract: 772,560. Thermionic valves. SYLVANIA ELECTRIC PRODUCTS, Inc. April 19, 1955 [April 19, 1954], No. 11321/55. Class 39(1). A cathode is separated by insulating wafers from a grid on either side, the assembly being held together by ears on one grid being bent over the other grid. The assembly shown is of the stacked type, the cathode sleeve 10 being supported by its wire loops 16 between insulating wafers 52, 54. The grids 20, 22 on either side have upstanding ears at each corner, as at 26 and 28. The ears 28 are longer than the ears 26, and spaced a little more widely apart, so that in assembling the grids, cathode, and insulators 52, 54 together, the ears 26 lie just inside the ears 28, with their ends level. A further insulator 50 is placed on the stack, and then the ears 26, 28 conjointly bent over the upper insulator 50, and welded together ; thus these elements now form a complete unitary sub-assembly. The anodes 30, 32 are of channel section, each having end web portions 36, and a central platform 38 (forming the active anode area) of less height than the portions 36. Ears 42 on anode 32 are longer than the corresponding eats 40 on anode 30, so that the ends come level after assembly of the complete doubletriode, and are then welded together: The assembly is supported from pins passing through the alumina base 70; a cross-bar 74 welded to two of these pins is welded to the under side of platform 38 of anode 32. In a simplified form of the assembly, the insulators 50, 56 may be omitted. The insulator 54 then rests directly on the web portions 36 of the lower anode. The grid is of such a length that it is clear of the web portions, and is also spaced from the anode surface 38. A modified form of grid consisting of wires secured to a ceramic frame, Fig. 4 (not shown), may be used.
Patent GB-809311-A (GB)
Title: A method of manufacturing a supporting dressing for broken bones and other injured parts
IPC: A61L15/07
Filed: 1957-04-08
Abstract: A material suitable for making a rigid supporting dressing is made by immersing a loosely woven textile fabric in a mixture of an aqueous emulsion of a hard plastic material and a binding agent which is dissolved or dispersed in water and is active as a binding agent when dry and which is also insoluble in a solvent for the hard plastic material, and the fabric is then dried.  Hard plastic materials are defined as synthetic resins having a brittle point above 20 DEG  C. such as polymethylmethacrylate, polyisobutylmethacrylate and polystyrene.  Binders specified include polyvinyl alcohol, casein, water-soluble cellulose derivatives (e.g. sodium carboxymethylcellulose), water-soluble acryl products (e.g. polyacrylamide and salts of polymethacrylic acid), polyvinylpyrrolidone and water glass.  The dried fabric may be dipped into a solvent for the hard plastic material and applied to an injured limb in six or eight windings.  Suitable solvents include ketones (acetone, methylethylketone), esters (ethyl and methyl acetates), acetals dimethyl formal, diethylformal and dimethylacetal) and chlorinated hydrocarbons (methylene chloride, ethyl chloride, isopropyl chloride, butyl chloride and dichloroethylene) and other low-boiling non-toxic compounds.  The rate of evaporation and/or the flammability of the solvent may be regulated by addition of low-boiling esters, paraffin hydrocarbons and fluorochloro-hydrocarbons.  In an example a loosely-woven spun rayon fabric is dipped into a mixture of an emulsion of polymethylmethacrylate and polyvinyl alcohol.  The treated dried web is then immersed in acetone, excess solvent removed and the web applied to an injured limb to form a rigid dressing.  Specification 780,795 is referred to.

The rollers are then stopped to allow this metal to cool and then the operation is repeated. A saw 14 is arranged and operated to sever the bar, preferably at the point of contact of successively solidified lengths, the ingots cut off being removed by a conveyer, not shown.

Patent GB-563172-A (GB)
Title: Improvements in or relating to the finishing of textiles
IPC: D06M15/423
Filed: 1942-08-15
Abstract: Cellulosic textile materials are weighted, given a soft, springy handle, rendered resistant to shrinking or creasing, and rendered water-repellent, by impregnating them with an aqueous solution of a water-soluble methylated methylol-melamine, and thereafter curing the melamine compound, e.g. by heating, so as to render it substantially water-insoluble.  In an example, a cotton fabric is impregnated with an aqueous solution of the melamine compound, tacked to its original size, dried, and cured for several minutes at 200-300 DEG  F.  The fabric is rendered resistant to the shrinking action of a hot solution containing soap and sodium carbonate.  If the amount of melamine compound incorporated is of the order of 8-14 per cent by weight of the fabric, there is imparted a substantial resistance to creasing as well as to shrinking.  The aqueous solution of the methylated methylol-melamine may be applied by immersion of the fabric or by spraying.  The moistened fabric may be passed through rolls as in a padder or mangle to secure uniform impregnation and to remove excess of resin.  To speed up the curing of the resin, a catalyst may be added to the aqueous dispersion of the melamine compound. Oxalic acid, ammonium phosphate, methyl hydrogen pyrophosphate, triethanolamine phthalate, zinc chloride, acetic acid, or dilute hydrochloric acid, may be used as catalyst.  The water-soluble methylated methylol-melamine may be obtained by known methods, e.g. 2-6 mols. of formaldehyde are reacted with 1 mol. of melamine to form a condensation product which is mainly methylol-melamine, and this product is then reacted with 2-6 mols. of methanol.
