Title: Improvements relating to electric heating elements, and method of making same
Inventor: KEMP ALLAN JOHN
IPC: H01C7/00
Filed: 1950-06-12
Abstract: 714,576. Electric heating resistances. UNITY HEATING, Ltd. Sept. 10, 1951 [June 12, 1950], No. 14659/50. Class 39 (3) An electric resistance element for heating comprises a solid body of closely packed or felted non-conducting fibres of a substantially heat staple fibrous material, e.g. mineral fibres such as asbestos (other than glass), the individual fibres being coated with conductive particles of colloidal size directly adsorbed thereon. An aqueous colloidal suspension of metal or graphite is mixed with a dispersion of asbestos fibres in water and the colloid is precipitated, whereby the metal or graphite is wholly adsorbed by the fibres to form a thin coating thereon, leaving clear water, which is then removed, and the fibres are formed in a sheet by paper making technique. The sheet is dried at 200‹-400‹ C. to volatilize any inorganic matter used as a colloidal protective agent, and contact strips, either parallel or converging, are applied to the sheet, e.g. by spraying metal. The thin flat sheets may be curved, e.g. to form corrugated sheets or tubes, the shape being maintained by incorporating sodium silicate solution before bending and drying the sheets after bending. When a gummy protective agent has been added to the colloidal graphite, it is rendered inert by adding hydrochloric acid until the mixture has a pH value of 6. The asbestos may be previously treated by washing' first with dilute hydrochloric acid and then with water. The metal coating may be a nickel chromium alloy reduced to colloidal state mechanically or by striking an arc between wire electrodes at about 100 volts under water preferably containing a colloid protecting agent, the electrodes being moved by a device to maintain their distance apart constant as they are consumed. As the resistance of metals increases with temperature rise and that of graphite decreases with temperature rise, the colloidal graphite may be mixed with the metal colloid to give a resistor of zero temperature coefficient of resistance. Holes may be drilled in the sheet to modify the resistance. The sheet is normally used with a surface temperature up to 250‹ C.

Title: Improvements in or relating to nickel-base compositions
IPC: H01J1/32
Filed: 1954-05-19
Abstract: An alloy particularly for secondary emission purposes, consists of nickel and a metal of sub-group IIA of the periodic table, the said metal being present in an amount greater than that which can be taken into solid solution in the nickel, but not more than 10 per cent. The alloy is softened by heating, e.g. to 1100 DEG C., followed by quenching, reheated to a temperature, e.g. 450 DEG C. and for a period suitable to homogenize the alloy and then reheated to a higher temperature, e.g. about 800 DEG C. for about 6 hours, in an oxidizing atmosphere.  Before the second heating the alloy may be subjected to pressure, e.g. about 10 kg./cm2 at a temperature slightly below the melting point of the alloy.  The use of alloys containing 2.5-4.5 per cent of beryllium and of alloys containing 0.6-2 per cent of magnesium is referred to.

Abstract: 543,857. Obtaining cellulosic fibre masses; paper boards ; wood. substitutes plastic compositions. BASLER, H. May 17, 1939, No. 14791.. Convention date, May 17, 1938. [Class 2 (ii)] [Also in Group VIII] A moulded article of fibrous vegetable material is obtained by first reducing the fibrous material to coarsely divided form by mechanical means, sifting to remove dust and mealy substances, cooking for the partial removal of semi-cellulose, resins, pentosanes, pectines, lignin, silica, and other constituents, pressing between rollers to loosen the fibre bundle structure in the longitudinal direction, treating in a refiner to a sufficient extent to separate the fibrous material into individual bundles and chains of fibre bundles, and then moulding the material to the desired shape. Wood, straw, and like material may be treated. For the cooking treatment, a solution of caustic soda may be used. With a 4-10 per cent. solution at a pressure of 8 atm., the boiling may be continued for 2-5 hours. A more prolonged treatment is required if sodium carbonate is used. The cooked material is passed between a pair of pressing rolls in such manner that the chips or other pieces are split and the fibre bundles loosened in the direction of their natural growth. The material is then subjected to a short treatment in a refiner till it consists mainly of separate fibre bundles and chains.of fibre bundles. Some separate fibres and fibrous pulp may also be formed. The fibrous material is then moulded, e.g, by pressing and heating. The material, prior to moulding; may have binding, hardening, or waterproofing substances incorporated with it, e.g. natural or artificial resins, casein, or drying oils. The moulded bodies, e.g. plates, show surface graining effects. Preferably the fibre bundles and chains of fibre bundles are irregularly felted and positioned in at least one direction, e.g. the longitudinal direction of the moulded body.

Filed: 1968-03-28
Abstract: 1,168,603. Making coils. UNITED STATES ATOMIC ENERGY COMMISSION. 28 March, 1968 [10 April, 1967], No. 14933/68. Heading B3A. [Also in Divisions G6 and H1] In a method of making a magnetic coil 11 free of bending moments, a pliable conductive wire is formed to the approximate shape of the coil, the wire being defined by a series of consecutive regions, each of the regions being subject to magnetic bending and tension forces from other regions when a current flows in the wire. Pairs of the regions are connected with insulated bars 12, 13 to prevent relative motion of the pairs and to oppose tension forces due to the currents. The wire is then pulsed with an intense short duration current pulse so that the bending forces permanently displace the relative positions of the regions until the bending forces therein are balanced. The coil 11 may be made of a superconducting material. The bars are preferably positioned in regions across which the magnetic deformation forces are greatest and they are attached with means responsive only to tension forces. Annealed aluminium and copper conductors having round cross-sections have the best forming properties.

Oct. 9, 1940, No. 15056. Drawings to Specification. [Class 2 (iii)] Anthracene, phenanthrene, and carbazole are extracted from crude oil derived from heavy distillation of coal tar by the use of selective solvents for these compounds, temperature and its rate of change being so controlled as to form large crystals facilitating centrifugal or other filtering. Anthracene oil may be rapidly cooled from 80 to 40‹ C., surplus oil centrifugally extracted while washing with a first solvent to remove some of the phenanthrene and completely dry the anthracene which is mixed with a further quantity of the same solvent and heated to dissolve the remaining phenanthrene, and then further cooled and centrifuged, mixed with a second solvent, and cooled in a manner to promote the growth of anthracene crystals while leaving the carbazole in solution ; further solvent may then be added and the growth of carbazole crystals promoted by controlled cooling, and the remaining substance again centrifuged. Anthracene of 99 to 100 per cent. purity may be obtained by fusing with sodium and potassium salts and subliming. Phenanthrene of 99 per cent. purity may be obtained by fusing .with sodium and potassium salts, distilling, and crystallizing. Carbazole.of 99 per cent. purity may be obtained by sulphonating the anthracene and phenanthrene left in the mass, filtering, and subliming. Solvents specified include coal tar distillates, low boiling point mineral oils, carbon tetrachloride, and acetone.

In a furnace installation in which a recuperator 8 and a water heater 15b or steam generator associated with one or more shaft or other industrial furnaces 1 are disposed in parallel in the waste gas stream, the distribution of waste gases between the recuperator and the water heater or steam generator is automatically controlled by the temperature of the hot blast produced by the recuperator. A further heat exchanger 15a is heated by hot gases from the heater 15b and from the recuperator 8. In the form shown, feedwater supplied at 14 and return water from heat consumers 17 are heated in the heaters 15a, 15b, and supply a steam generator 4 which is heated by the combustion of waste gases from the furnace 1. Steam passes from the boiler 4 to a heat accumulator 16 and heat consumers 17. The hot gases from the boiler are separated from dust in a separator 5. The dust may be returned to the boiler for burning if it contains much fuel and for melting if it is ash. The boiler may be equipped for additional or independent firing. The boiler combustion chamber 3, the recuperator 8 and the heat exchanger 15b may be combined in one unit. The blast is pre-heated in a heat exchanger 19 by steam or hot water which may be circulated by a pump 20. The hot blast from the recuperator 8 may be further heated either in a regenerator heated by fresh hot gases from the furnace, or in ducts in the boiler combustion chamber 3.
