Title: A new method and apparatus for removing amatol from shells or the like explosive bodies for the purpose of recovering the ammonium nitrate
IPC: C01C1/18
Filed: 1919-08-14
Abstract: 153,123. Beakbane, C. F., and Arnot, J. W. Aug. 14, 1919. Explosives, apparatus for making, testing, and treating.-Relates to a method and apparatus for the recovery of ammonium nitrate from explosives, such as amatol and ammonal, employed in shells, in which the explosive is removed from the shells by the circulation therethrough of hot water under pressure, the resulting solution, after precipitation and separation of the contained trinitrotoluene, being evaporated down to cause crystallization of the ammonium nitrate. According to the invention, hot water at 86‹ C. and under a pressure of 25-55 pounds per sq. in. is circulated until the liquid attains a density of 50‹ Tw., and, after separation of the trinitrotoleuene, is concentrated to 72‹ Tw. for crystallizing out the ammonium nitrate. In the apparatus illustrated, water in a tank 3 is heated by highpressure steam coils 8 to a temperature of 86‹ and is drawn by a centrifugal pump 11 through pipes 13, 14 to jets 16 from which it is driven at a pressure of 25-55 lbs. to the sq. in. into the superposed shells 17. The resultant solution is delivered by way of a trough 18 and pipe 19 to a settling tank 5 from which it is returned to the tank 3 through a pipe 4. When the solution has reached a density of 50‹ Tw., circulation is stopped by closing a valve 21, and a valve 22 is opened, causing the pump 11 to deliver the solution to a tank 20 in which the trinitrotoluene is allowed to precipitate. The supernatant liquor is then drawn off through a pipe 23 to an evaporating tank, concentrated to 72‹ Tw., and passed into a cooling tank to crystallize out the ammonium nitrate. Fresh supplies of hot water for the tank 3 are taken from the condensing tank into which the steam from the coils 8 is delivered.

Abstract: 220,164. Richmond, V. C., and Scott, G. H. Aug. 7, 1923. Aerostats.-Electric discharges between the inner and outer surfaces of the covering material of aerostats are prevented by electrically connecting the surfaces at frequent intervals. According to one method, a tinsel or other metallic thread is woven or sewn in, or passed through and secured to, the covering material. In another arrangement metallic studs are passed through the cover. The conductors may be conveniently inserted at the joints where the panels of covering material forming the envelope are connected together. A tinsel thread extended or looped laterally at intervals is sewn along the overlapping edges, the lateral extensions remaining exposed and connecting the inner and outer surfaces, after the strips used for covering the lap joints have been applied. One or more metal studs may be inserted in the centre of each panel. The invention is stated to be particularly advantageous in coverings composed of or incorporating india rubber or other insulating materials.

Abstract: 462,804. High-frequency transmission systems. STANDARD TELEPHONES & CABLES, Ltd. July -24, 1936, No. 20526. Convention date, Oct. 3, 1935. Addition to 420,447, [Group XXXVI]. [Class 40 (iv)] [Also in Groups XXXVI and XL] Relates to the transmission of high-frequency waves over a wave-guide of dielectric material (including air bounded by a conducting sheath) as described in the parent Specification and comprises improved means for coupling the terminal apparatus to the guide, means for producing transverse electric waves in the dielectric, and the use of a crystalline dielectric. The coupling means shown in Fig. 2 comprises coaxial conical members 7, 8 connected to a small length 6 of coaxial conductor cable to which a disc 9 is attached to reduce radiation losses. Radiation losses may also be reduced by placing the wave source within the guide, Fig. 4, between two copper discs 19, 20, the outer end of the tube being closed with an adjustable reflector 21 carried by a rod passing through the end-cap. In other arrangements described but not forming part of the invention, the supply conductors enter through the end which is open but provided with a reflector, and the source may be connected to Lecher wires disposed along the axis of the tube or to a short-length of axially-disposed copper tubing and by a radial wire to the tube. In the arrangement shown in Fig. 5, the source 2 is connected by adjustable telescopic Lecher wires 22 to an internal disc 23 and to an end disc 24 fitted with a short-length of coaxial-conductor cable 6. The latter may be omitted and the disc 24 may also be omitted, one connection then being made direct to the edge of the tube 5. In Fig. 8, connection is made by angularlyarranged conductors 25, 26 of which the latter is projected into the open end of the tube 5, a reflector 17 being arranged as shown. In another arrangement, a Lecher-wire connection to cones as in Fig. 2 is connected to Lecher-wire connections to the source, the two sets of Lecher-wires being at right-angles. To produce transverse electric waves, the source may be connected to arcuate conductors 27, Fig. 10, connected in series by radial conducting loops 28 or in parallel to two central electrodes. In another arrangement, two semicircular current loops connected in parallel and with intermediate phase-adjusting loops may be employed. Crystalline substances such as quartz may be employed for the wave guide to give low losses. The guide may comprise one or more crystals which should preferably be arranged so that the axes of greatest di-electric constant are parallel to the axis of the guide. Fig. 15 shows a hollow copper cylinder 5 filled with crystals 37 and of a cross-section corresponding with the differences in dielectric constant in different directions.

Abstract: 360,844. Reproducing sound and picture films; projection printing apparatus. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and COCKE, K. J. R., 46, Dale Street, Rugby. July 11, 1930, Nos. 21064 and 38345. [Class 98 (i).] In a projection printing apparatus for printing from a negative on to a positive of different dimensions, the films are caused to pass through the apparatus by means of two coaxial drums (e.g. sprocket feed drums) mechanically locked together, and having the necessary ratio of diameters. For varying the linear dimensions of the printed image in one direction a cylindrical lens may be used. To reproduce a wide sound-track negative film 9 on to a narrow positive film 7 the wide film passes over a sprocket drum 1 having one row of teeth 2, and a side disc 6 supporting the opposite edge. The narrow film 7 passes over a coaxial sprocket wheel 8. The positive film must move in the same direction as the image. In the construction shown the films 7, 9 pass in opposite directions through tensioning devices 14, 15 respectively, at speeds the ratio of which is the reproduction ratio of the lens 12. The positive film passes over the roller 18 past the rear of the focal plane.
