Title: Luminescent compounds
IPC: C09K11/73
Filed: 1945-05-23
Abstract: 592,157. Luminescent materials. BRITISH THOMSON-HOUSTON CO., Ltd., and WELLS, R. S. May 23, 1945, No. 12897. [Class 39 (i)] Luminescent materials for use as coatings on the envelopes of low-pressure discharge lamps, as screens for cathode-ray tubes or as paints for advertising and decorative purposes comprise the fluoro-phosphate, the chloro-phosphate or the fluoro-chloro-phosphate of barium with uranium as an activator. Luminescent material comprising the chloro-phosphate of barium is prepared by forming an intimate mixture of barium phosphate and barium chloride in the proportion of three mols. of phosphate to from one-half to two mols. of chloride, with up to 20 per cent and preferably between 6 per cent and 7 per cent, by weight, of the combined weights of phosphate and chloride, of uranium oxide, firing the mixture at a temperature of between 900‹ and 1000‹ C. and reducing the resulting product to a fine powder. The barium phosphate employed is one which is no more basic than Ba3(PO4)2 and may be prepared by precipitation from a solution of BaCl2 by (NH4)2HPO4 in the presence of sufficient NH4OH to make the liquid slightly alkaline. The precipitate is believed to consist of Ba3(PO4)2 with a small proportion of BaNH4PO4. The barium chloride may be replaced either wholly or in part by an equivalent molecular proportion of barium fluoride. The barium fluoride may be prepared by precipitation from a solution of barium nitrate by a solution of potassium fluoride; The uranium oxide may be replaced by such a quantity of another uranium or uranyl salt as to supply, during the firing process, an amount of uranium equivalent to that given by the required amount of uranium oxide.

Title: Improvements in straight bar knitting machines
IPC: D04B11/00
Filed: 1945-05-25
Abstract: 619,490. Knitting-machines. BERRIDGE & CO., Ltd., I. L., and COLTON, L. H. May 25, 1945, No. 13076. [Class 74(ii)] During the manufacture of a stocking the normal movement imparted to the needles for the purpose of causing the beards of the needles of a straight-bar machine to press, is varied to avoid pressing and additional members are adapted to engage the plain sides of groups of needles to cause them to press. The invention is described in connection with the formation of heel tabs, for which purpose the members are constituted by blade elements 14, 15, each adapted to engage one group of needles knitting a heel tab. The elements 14, 15 are mounted on arms 12, 13, formed in two parts 12a, 12b, and 13a, 13b, hinged at the centre to permit the elements to be swung to an inactive position. The arms 12, 13, are mounted on rods 7, 8, each of which is adapted to be moved longitudinally and both of which are supported in bearings 9 rotatable through linkage 11. When it is desired to commence the formation of heel tabs, the normal pressing movement is modified so that the needles do not press and the blade elements are operated by linkage 11 to engage the plain sides of the groups of needles and to press them against the presser bar 3. If it is desired to increase or decrease the number of inactive needles between the blade .elements, the rods 7, 8, are moved accordingly. Alternatively, the narrowing machine may be adapted to support the members in which case the members engage the heads of the needles. The means for moving the rods 7, 8, longitudinally may be associated with the movement imparted to the narrowing points. Specification 576,662 is referred to in the Provisional Specification.

Abstract: 423,147. Overhead travelling cranes. PETERSEN, R., 8, Forsterstrasse, Oliva, Danzig Free State. May 2, 1934, No. 13277. [Class 78 (iv)] In a hoisting and traversing apparatus the main cable 1 is attached at 3, 3 to the loadsupporting frame 4 and also passes under a pulley 6 at the top of the frame. The cable 1 passes also round fixed pulleys 2 and a winding drum 7 and is sufficiently long to allow a fair amount of sag. The pulleys 2 and 6 are large and of the same size. The hoisting cable 9; fixed at 13 and passing over a pulley 10, is so disposed as to lie substantially parallel to the cable 1 between the frame 4 and the supporting pulleys 2, the parts 10, 13 thus taking up some of the load which would be transmitted to the frame 4 were the traverse parts of the cable 9 horizontal. The pulleys 11 on the frame 4 are disposed apart sufficiently far to allow the parts of the cable 9 between them to be inclined to the vertical and to lessen longitudinal surging. The cable 9 may be fixed to the load 5, and then passes round pulleys co-axial with pulleys 2 to a pulley block which can be raised and lowered by a winch rope having a tension-limiting weight attached. Cables may also be added for controlling a grab. In each case any cable may be duplicated to lie symmetrically about the others.

Patent GB-134579-A (GB)
IPC: A62C3/06
Abstract: 134,579. Ellis, C. A. Sept. 25, 1918. Fire-extinguishing by foam etc.; chemicals and substances.-A fire-extinguishing apparatus, more particularly for protecting oil-tanks, comprises a number of tanks 7, 8 containing foam-producing extinguishing-liquids normally maintained under discharge pressure suppled by a compressor through pipes 10 connected to discharge pipes 14, which are normally free from liquid and under the same pressure as that in the tank. These discharge pipes are connected through reducing- valves 16 to the distributing-pipes 17, 18, which lead to the oil tanks that are to be protected, so that, if the pressure in the tank is 75 lb. per sq. in., that in the distributing-pipes is 20 lb. per sq. in. The pipes are connected together as shown. In operation, the valves 16, 19, 23 and 13 are open and valves 24, 27, 28, and 32 are closed. When a fire occurs, the fusible plugs in the pipes 17, 18 are opened, and pressure on the pipe lines is released and the solutions are forced along the pipe lines to a mixing-chamber, forming foam containing carbon dioxide, which passes to the oil tanks. The pipes 17, 18 may be connected to manifolds leading to the different oiltanks and provided with both manual and fusible controls. In 'addition, the pipes 17, 18 may be connected through stop-valves to hose. Should pressure fail when a fire occurs, the liquids may be forced out of the tanks by means of air supplied by a compressor through the pipe 12. The solutions may be agitated from time to time, by closing valves 19 and 13 and opening valves 12, 23, and 32 so that air passes through pipes 9, the horizontal parts of 10 and 21, and down the pipe 14, through the solution, and out of the valves 32. In re-charging with compressed air, the valve 13 is opened and air fused in until a pressure of 75 lb. per sq. in. is reached, when the valve 23 is closed and the valve 19 opened. Suitable solutions are a solution of 10 per cent sodium bicarbonate in water, for one tank, and for the other tank, 12 per cent aluminium sulphate and 3 per cent Greek liquorice in water. The' Greek liquorice may be replaced by " foamite," in which case the " foamite " is added to the bicarbonate solution.
