摘要： 815,010. Respiratory appliances. WILKINS, E. T. Jan. 31, 1958 [Nov. 7, 1956], No. 34044/56. Class 81 (2). A mask 11, which may be of transparent plastic material, is held slightly spaced from the wearer's face, and a container 14 is provided to emit a gaseous or vaporous reagent into the intervening space so as to neutralize atmospheric acid in fog &c. The mask may be made from a flat sheet of material with a V-cut in its lower edge so that the edges of the cut may be overlapped and held together by press studs 16. Other studs 18 are provided to carry a chin strap and the whole mask is held in position by elastic head straps 13. The container 14 may enclose ammonium carbonate, vapour from which passes out through a small vent hole, or alternatively it may hold cotton wool soaked in a liquid source of ammonia.

摘要： 347,202. Centrifugal machines. WILKINS, E. T., H.M. Fuel Research Station, Blackwall Lane, East Greenwich, London. Dec. 20, 1929, No. 39029. [Class 23.] Mixtures of solid materials such as coal, coke, breeze, and ores, are separated by means of a member having a concave surface and rotating about a vertical axis, so that the mixture forms a number of zones on the surface. The constituent of each zone is separately removed. A pan 1, Fig. 1, has a central discharge passage 2 ; the material is fed on to it near the periphery and after its division into zones is removed by scrapers or other suitable means. The fraction which collects near the centre of the pan may be discharged through the passage 2. The pan may be divided, for instance, into three sections 3, 4, 5 as shown in Fig. 2. The annular members 3, 4 and the remaining part 5 may be rotated at the same or different speeds. Some of the separated material is projected over the outer edge of the section 3 or is removed by scrapers, and the portion which moves inwards from the section 3 undergoes further separation on the section 4. Some of this portion is projected over the upper edge of the section 4 into the section 7 of a second rotary pan 7. Similarly, another separation occurs on the section 5, and material is discharged into the section 8 ; the material which tends to accumulate near the axis is discharged through the passage 6 into the innermost section 10. The surfaces of the pans may have indentations or ribs, and may be formed of overlapping plates arranged so that the reaction between the surface and the material can be modified. Sweepers, or burnishers, or an air current may be used to keep the surfaces in condition, and the surfaces may be heated or cooled. The pan may be formed of radial overlapping and slightly flexible sections to permit of slight changes in the concavity.

摘要： 560,042. Pitch. WILKINS, E. T., and SAYLES, C. P. Nov. 19, 1942, No. 16367. [Class 55 (ii)] To prevent the suspension of fine pitch dust in the atmosphere, pitch is treated with a small proportion of oil, grease, wax, gum, resin, or a hydrophilic colloid, for example 05 per cent by weight of oil. Starch or metallic-alginates are examples of a suitable hydrophilic colloid, and may be used in the form of a solution or dispersion in water with about . 1 per cent of a wetting agent such as a sodium alkyl sulphate. The treating agent may be added to the pitch before it enters the grinding mill, or sprayed on to the ground pitch after grinding.

摘要： 386,312. Gravity-separation apparatus. WILKINS, E. T., Fuel Research Station, Blackwall Lane, East Greenwich, London. June 4, 1931, No. 16193. [Class 46.] A settling tank, particularly applicable for separating suspensions of coal and associated impurities, is provided with a number of inclined baffles and its inlet and overflow outlet are at the same level so that liquid passes from the inlet to the outlet as a horizontal stream over or between the upper ends of the baffles. The distance between the baffles in a horizontal plane is considerably less than their average height. Fig. 1 shows a conical tank with baffles PI in the form of conical frustra. There is a central inlet F1 surrounded by a perforated distributer B1, a peripheral overflow W1, and a sediment outlet E1. Modifications are described in which (a) the conical frustra are upright instead of inverted and (b) the baffles take the form of parallel tubes or of a multi-start spiral with vertical axis. Fig. 4 shows a form with inlet F4 and distributer B4 at one side, the clear liquid outlet W4 being at the other side. The baffles are built up of units, as shown in Fig. 5, each unit consisting of a number of plain or corrugated plates spaced by rods G. In the form shown in Fig. 7, one of the baffle plates Q is extended to the wall of the tank and an additional outlet R is provided so that the different classes of sediment collecting in the two portions of the tank are discharged separately. Fig. 8 shows a tank which may be rectangular in plan and which has three separate sediment-collecting compartments. It is stated that arrangements may be made for continuously or intermittently moving the whole system of baffles.

摘要： A portable distilling outfit for use where a large open body of coolant, e.g., the sea or a river, is available comprises a container adapted to house all the parts when the outfit is not in use, a boiler which, when the outfit is in use or housed out of use, is supported in the upper part of the container and is so shaped as to leave but a narrow passage between itself and the inner wall of the container, a burner, a condenser in the form of a vessel which when the outfit is not in use can be housed within the container below the boiler and which is entirely closed except for a steam inlet and a vent so that it can be submerged in the open body of coolant, and a flexible steam pipe which connects the boiler with the condenser. In Fig. 1 the boiler 1, which is a cylindrical vessel provided with anti-surge baffles 9 and an anti-priming device 10 is supported by a flange 7 within the container 29. The wall of the boiler is corrugated (see Fig. 2) and an outer cylinder 3 fits closely over the crests of the corrugations; the base of the boiler is provided with thimbles 2. The boiler is provided with a pivoted handle 14 and filling opening 15 which are so relatively placed that when the boiler is dipped in the sea and withdrawn by the handle, it retains water to the correct level. The condenser 17 is a cylindrical vessel of thin metal provided with a vent pipe 22 and connected with the boiler by the flexible steam pipe 21. The burner comprises an outer cylinder 25, the lower portion of which receives the fuel, and an inner perforated cylinder 26. An alternative form of condenser consists of a vessel of annular cross section.

摘要： 681,720. Underground gasification of coal. MASTERMAN, C. A., and WILKINS, E. T. Dec. 1, 1950 [Nov. 7, 1949], No. 28519/49. Class 55 (ii) An area for combustion in an underground system for gasifying coal is established or extended by ,forcibly pumping a fluid or causing a fluid to permeate through the coal, and/or between the coal seam and its roof or floor. Compressed air is supplied at a pressure of about 100 lbs. per sq. in. to a bore hole or one or both of a pair of adjacent bore holes. The bore holes are preferably lined and may be close to an existing underground system of gasification. In a modification water or other liquids is forced into one or a pair of bore holes and allowed to permeate through the coal. The liquid used may contain solvents such as pyridene or acids.

摘要： 578,369. Mineral oil compositions. HURLEY, T. F., and WILKINS, E. T. Nov. 15, 1941, Nos. 14726/41, 14727/41 and 16208/42. [Class 91] [Also in Groups X, XXIX and XXXIII] Apparatus for applying a film of waterproofed dust to the surface of water to reduce its visibility from the air comprises means for discharging the dust in a current of fluid such as air in such a manner as to disperse the dust on the surface of the water. In the apparatus shown, which is mounted on a boat, the dust is stored in a hopper 3 from which it is drawn by conveyers 4, 4 driven by engines 5, 5' and discharged into the air inlets of two blowers 6, 6' driven by an engine 7. An oil pump 8, also driven by the engine 7, supplies oil to two sprayers 9, 9' discharging into the inlet ducts of the blowers 6, 6 . The same pump may also supply oil, e.g., marine fuel oil mixed with three times its volume of paraffin burning oil, on to the water at the stern of the boat. The dust particles become oil coated in the blowers and are carried through ducts 10, 10' to be discharged into the water by hose pipes 11 having holes 13 just below the surface. Preferably coal containing 85 to 91 per cent. of carbon ground as finely as that commonly employed for powdered fuel firing is employed, the particles being waterproofed by 0.5 to 5 per cent. of fuel oil with or without paraffin oil.
