Patent GB-385217-A (GB)
Title: Anhydrous borax (sodium tetraborate), process and apparatus for making it
IPC: C01B35/12
Filed: 1932-06-14
Abstract: <PICT:0385217/III/1> <PICT:0385217/III/2> Anhydrous crystalline borax is obtained by heating a hydrated borax until the fused state is reached, say to 780 DEG  C., and then permitting the molten borate to cool whilst inducing crystallization within the fused mass. Crystallization is assisted by slow cooling, agitation, seeding, and escape of residual water.  The colour of the crystals is improved by adding to the initial material a small quantity of an oxidizing agent such as sodium nitrate to remove organic matter present.  As shown in Fig. 1, the hydrated borax may be treated in a furnace comprising a burner 1 and a refractory arch 2 from which heat is radiated on to the mass of borax 21, which rests at substantially the angle of repose.  As soon as the surface layer of borax becomes molten, it passes to a collecting trough 25 and thence to a mould 27 where crystallization takes place.  Hydrated borax is fed from hoppers 12 to an annular rotating feed chamber 13 carrying force-feeding vanes 18, Fig. 2, co-operating with doors 19 in the furnace wall to feed borax into the furnace chamber. The position of the arch 2 is preferably adjustable, and it is supported by water-cooled tubes 4 and protected by a water jacket 3.  Water jackets 23, 24 are also provided at the points where solid borax and the molten material respectively enter and leave the furnace.

Title: Improvements in and in the manufacture of piston and like packing rings
IPC: C21D9/40
Filed: 1942-11-30
Abstract: 558,408. Powder metallurgy. BRITISH PISTON RING CO., Ltd., TWIGGER, T. R., and JUDD, J. A. Nov. 30, 1942, No. 16969. [Class 82 (i)] [Also in Group XXII] Piston rings. particularly those made from metal powder, are manufactured to the required special shape by heating on a primer in a non- oxidizing or neutral atmosphere, such as cracked ammonia, burnt ammonia, coal gas, burnt coal gas and producer gas, which may fill the furnace, in which case the rings may remain in the furnace during the heating, making and cooling periods. The furnace may be of the conveyer type with separate zones for the various periods. In a modification the rings are placed in a container with inlet and outlet pipes for the gas, the container being removed from the furnace for cooling. Rings for hardening by quenching in water, oil or air are treated on primers and heated in non-oxidizing atmosphere, and this operation may be the final operation in manufacture. When final machining such as by grinding is, however, to be given, the absence of scale enables accurate location to be made.

Abstract: 405,248. Flashlight lamps. HARKER, J. A. M., 28, Victoria Street, London. June 23, 1932, No. 17794. [Class 75 (i).] Flashlight lamp bulbs or vessels containing a mixture of combustible gases, a decomposable gas such as chlorazide, or a readily combustible material and oxygen or an oxygen yielding gas at sub-atmospheric pressure are provided with an opening sealed by a gas-impermeable closure member having, or adapted to have, associated therewith means whereby the filling may be ignited by an externally applied device, the construction being such that no part of the sealing or ignition means projects into the body of the bulb and that the bulb remains substantially closed before and during the ignition of the filling. Fig. 1 shows one form in which a bulb 1 containing aluminium foil 2 and oxygen under reduced pressure is sealed at its neck 3 by a sheet metal diaphragm 4 engaging a beaded edge 5 on its neck. The diaphragm 4 may be of reduced thickness at its centre 6 to facilitate its penetration by a needle-like member having adjacent its point an eye or recess to expose a filament or spark gap connected to an external source of electricity. In another form a central aperture in the diaphragm is covered by a rubber flap allowing the insertion of a tube by which the bulb is exhausted and filled with gas. The rubber flap may subsequently be sealed to the diaphragm by plastic material or by applying a covering of metal or foil. In a further construction the closure member consists of a rubber plug preferably provided on its inner surface with a layer of gasimpermeable material or sealed by an external metal diaphragm. The plug may have a central indentation to facilitate the entry of the igniting device and may carry an exhausting and filling tube. Fig. 6 shows the provision on a bulb such as shown in Fig. 1 of a rubber sleeve 17 which collapses when the igniting needle 12 is forced through the diaphragm 4. Alternatively the needle may be carried by a telescopic casing adapted to clip over the beaded edge of the neck of the bulb or to screw into a sleeve member attached to the neck. Fig. 11 shows a flash-light bulb fitted with a sealing member consisting of a metal diaphragm 19 having sealed at its centre a percussion cap 20 or similar igniting device. The bulb is adapted to be attached to a firing device consisting of a body portion 23 containing a spring operated hammer 24 which is released by means of a lever 26 and reset by operating a fingerpiece 27. Alternatively the percussion cap may be fired by a hammer operated electrically or controlled from a distance. In another construction an ignition mixture is inserted in the closure member and is ignited by applying a lighted match.
