Title: Thermoplastic explosive pelleting process
IPC: B29B9/00
Filed: 1944-07-06
Abstract: 723,641. Pelleting explosives, explosive compositions. GUENTHER, E. G., and BURTON, R. C. July 6, 1944 [July 16, 1943], No. 12895/44. Class 9(2). [Also in Group V] Thermoplastic explosive substances and compositions are made into free-flowing readily remeltable pellets having a shape resembling an unopened rosebud (see Fig. 7) by forming continuously a succession of discrete globules of viscous molten explosive by extrusion by gravity through a group of heated tubular elements through which flow is interrupted intermittently. The explosive is placed in steam jacketted kettle 7 consisting of concentric nesting pots 20, 21 (Fig. 4) with steam inlet and outlet 23, 22. The explosive is maintained at a constant level to obtain drops of uniform volume. The explosive is stirred by driven twisted anchor agitator and cut-off device 25 having upturned ends and flows through a number of steam jacketted extrusion tubes 24, spaced to provide uniform feed, in the base of the kettle. The resulting discrete globules 9 (Fig. 1) fall through air onto endless moving stainless steel belt 4 carried on rotatably mounted pulleys 2, 3, on frame 1 of which pulley 2 is driven. The kettle 7 is mounted above belt 4 at such a height that the uniform droplets will be formed in falling onto the belt. The droplets are carried forward on the belt between upper and lower air ducts 12, 13 having spaced outlet slots for blowing cool air onto both sides of the belt, and are solidified. The pellets fall from the belt into hopper 16 or are removed by wooden scraper 17 having collecting apron 18 which consists of a frame covered with cloth see Fig. 6 (not shown). The upper-run of belt 4 has supporting wooden skids 5 to prevent vibration and consequent formation of disc-shaped pellets. In an example water is placed in the kettle, T.N.T. is added, and the mixture agitated until the T.N.T. has melted. The contents of the kettle is allowed to come to rest when the water rises to the top. Moist cyclonite is added slowly through the water layer and the mixture again stirred. The water is decanted and heating of the molten mixture is continued until remaining water has been removed. Amorphous petroleum wax and an agent lowering the interfacial tension are added to the molten mixture maintained at 104‹C. Interfacial tension reducing agents are long chain hydrocarbon substitution products containing polar groups, e.g. carbonyl, carboxyl, or hydroxyl, such as fatty acids, e.g. stearic acid or the crude mixture of polar compounds (alcohols, ketones, carboxyl compounds, and esters) obtained by bubbling air through heated petroleum hydrocarbons in the presence of oxidation catalysts, e.g. manganese oleate.

Abstract: 1341886 Polyurethane foam OLIN CORP 4 May 1971 [28 May 1970] 13020/71 Heading C3R [Also in Division B5] Flexible polyurethane foam having at least two integral sections of different densities is prepared by (a) placing a polyurethane foamforming reaction mixture in a mould having means for limiting the free rise of a section of the foam formed therein, (b) allowing the mixture to rise to form a partially cured cellular material having at least two sections of different thickness but the same density, (c) 0 to 10 minutes after completion of the rise, applying compression to the partially cured cellular material to compress at least one section thereof to a fraction of its original thickness and (d) removing the compression and completing the cure of the cellular material with the proviso that where the period of time between completion of the rise and application of compression is between 0 to 2À5 minutes, 2À5 to 5 minutes or 5 to 10 minutes the partially cured cellular material is maintained at an environmental temperature between 45 and 400 F., 45 and 200 F. or 45 and 110 F. respectively for that period. Fig. 1 shows a simplified mould in which the process may be carried out, the mould 1 having an open top, an insert 2 which is lowered into the mould to a desired height h 1  (see Fig. 2) and a lid 3 having a cavity 4 for telescopically fitting into the open top around insert 2. The rising foam when it reaches height h 1  is prevented from filling the space occupied by inert 2 but rises to fill the spaces surrounding it. On compression by lowering the lid 3 the foam may be compressed to height h 1  (see Fig. 3) thereby producing two sections, an outer section 5 of compressed foam and an inner section 6 of undentified foam. The entire foam mass may then be compressed further to provide a foam consisting of two sections, an outer section of highly compressed foam and an inner section which is compressed to a lesser degree. Conventional polyurethane foam-forming reaction mixtures containing polyisocyanates, polyether or polyester polyols, blowing agents, catalyst and surfactants may be used.

Filed: 1941-10-10
Abstract: 551,729. Telephone instruments. SIEMENS BROS. & CO., Ltd., and SUTTON, G. W. Oct. 10, 1941, No. 13102. [Class 40 (iv)] In an electromagnetic telephone instrument having an armature of magnetic material which is supported at one place along its length and is free to vibrate at least at one of its ends, the armature has about it an electrical conductor closed upon itself and having a resistance such that it diminishes the rise of impedance with frequency of the instrument without producing substantial change in the amplitude-frequency response. The conductor may be a lapping of metal round the armature, such as a band or a winding of wire, or it may be formed by a deposit of a good conducting metal, such as copper or silver, on the armature. Fig. 2 shows an armature having slits 6 forming outer limbs 9 which support it so that it vibrates substantially about its centre line. A short-circuited copper band 5, which may be of copper strip 4 or 5 thousandths of inch thick, surrounds the armature close above the axis of vibration. It may be replaced or supplemented by a similar band 5a below the axis. In a modification, the armature is similarly slotted from both ends to form side supporting members which extend its whole length and are joined to it at the centre by narrow strips left between the inner adjacent ends of the slots. An armature supported at one end is also described. In all cases the supporting portions are gripped in U-section members four of which serve to space the pole pieces. Fig. 4 shows an instrument comprising pole-shoe stampings 11 with pole-pieces 12, 13 which are clamped to a magnet 14 and also to the members 4 carrying the armature 1 by screwing them to pillars 15.

Abstract: 131,974. Vickers, Ltd., Torazzi, M. F., and Webb, G. W. C. July 17, 1918. Torpedoes, locomotive. - Relates to jet-propelled torpedoes in which the gases generated by the combustion of a solid are passed through an ejector at the tail of the torpedo, intc which ejector water is drawn and expelled with the gases. According to the invention, the ejector comprises a number of nozzles arranged in series so as .to provide for the introduction of water in two or more stages. In the construction shown in Fig. 1, gas passes from the tube A containing the self-combustible solid to a discharging-tube D through a series of nozzles A<2>, B, C. Water is drawn in through apertures A<3> in the shell of the torpedo and passes through the annular channel between the middle nozzle B and the adjacent nozzle A<2>. Some of the water is vaporized, and a part of this steam is condensed by a second supply of water passing in through the space between the nozzles B, C. In a modification, the .combustion chamber is in the reax part of the torpedo, and the gases pass out through a forwardly-projecting nozzle, their direction then being reversed by passing into a tube having two rearwardly-directed limbs. In this case also, water is drawn in at two stages, between the various sets of nozzles.
