IPC: C06B47/00
Abstract: 1,052,853. Explosive compositions. AEROJET-GENERAL CORPORATION. March 13, 1964 [March 27, 1963], No. 10660/64. Heading C1D. An explosive composition having an oxygen balance of from - 25 to + 25 comprises an oxidizer and a liquid sensitizer comprising an organic compound of formula R(C1) n  where R is carbon or an organic radical and n is an integer from 1 to 10. The oxidizer is preferably ammonium nitrate in prill form but other compounds referred to are sodium nitrate, potassium perchlorate, ammonium perchlorate, calcium nitrate, calcium sulphate, and magnesium sulphate. Suitable chlorinated compounds are trichloroethylene, perchloroethylene, trichloroethane, carbon tetrachloride, chlorobenzene, chlorotoluene, chloronaphthalene, chlorostyrene, trichlorobenzene, trichloropropane, chlorocyclohexane, and nitro-chloroform. The chlorinated compound may be mixed with a hydrocarbon, substituted hydrocarbon, or graphite, for example benzene, naphthalene, toluene, xylene, hexane, octane, heptane, cycloheptane, methylcyclohexane, petroleum hydrocarbons, methanol, phenol, methyl ethyl ketone, diethyl ether, and diethyl ketone. A mutual solvent may be used to render the sensitizer mixture liquid; examples of such solvents are dimethyl ketone, methyl ethyl ketone, diethyl ketone, diisopropyl ether, methyl alcohol, butyl alcohol, and methyl isobutyl ketone. A lower nitroalkane may also be added to the sensitizer. Preferably the oxidizer is 25-100% saturated with the sensitizer, but excess sensitizer may be added, the mixture placed in a polyethylene bag, and used for underwater demolition. The explosive ingredients may be mixed at the site and, since the composition will explode in a small diameter bore-hole, it may be used in place of dynamite.

In a hydrostatic transmission having a variable displacement fluid pump and motor a lowspeed compensator system comprises a valve in a fluid conduit loop in parallel with the pump and motor and linkage means connecting the valve with elements controlling the pump displacement whereby the valve meters fluid flow in relation to pump displacement. Function summary.-The compensator valve reduces the pressure surges in the transmission during deceleration and acceleration of the vehicle in low speed ranges. A variable-displacement pump 13 supplies fluid to a motor 15 which may also be variably displaced. A manually-operable linkage 21 moves a valve 23 by means of a member 22 which is also connected to the swashplate 29. The valve 23 directs pressurized hydraulic fluid to pump cylinders 27 for controlling pump displacement. The valve 30 is arranged to vent some of the fluid from the high-pressure side of the circuit to the low-pressure side of the circuit at low transmission speeds, the valve being gradually closed as the pump displacement increases. The compensator valve may be operated intermittently when changes in pump displacement occur.

Abstract: 1,229,427. Methacrylonitrile polymer films and filaments. MITSUBISHI RAYON CO. Ltd. 25 March, 1968 [3 April, 1967], No. 14197/68. Heading B5B. [Also in Division C3] Films and fibres of an oriented crystalline polymer of methacrylonitrile having a monoclinic crystal structure with a=13À9A‹, b= 7À1A‹, c=7À6A‹ and #=97‹ 40' are obtained by stretching a film or fibre of the polymer and then subjecting the stretched film or fibre to heat treatment under tension at 120‹ to 180‹ C. The stretching is suitably carried out at 80‹ to 150‹ C. in the presence of a solvent or at 140‹ to 180‹ C. in the absence of a solvent. In examples: (1) methacrylonitrile polymer is mixed with dimethylformamide and the mixture is cast on a glass plate to form a film. After drying, the film is stretched between rollers heated at 90‹ C., and further stretched at 100‹ C. to twice its original length, which also frees it from remaining solvent. The film is then heat set at 140‹ C. at constant length. (2) Methacrylonitrile polymer is dissolved in trifluoroacetic acid, and the solution cast on a glass plate to form a film. Solvent is removed by extraction with boiling water, and the film stretched between rollers at 140‹ C., and then heat set at 160‹ C. while permitting 5% shrinkage. (3) Film made as in (2) is biaxially stretched at 160‹ C. to 3: 1 longitudinally and to 2:1 transversely and is then heat-set at 160‹ C. under tension. (4) Methacrylonitrile polymer is dissolved in trifluoroacetic acid and the solution is dry-spun into an atmosphere heated to 80‹ C. to form filaments, which are stretched to 5:1 by the use of a heated roller at 140‹ C. freed from solvent and then heat-set at constant length at 180‹ C. (5) A spinning solution made by dissolving methacrylonitrile polymer in 70% nitric acid is wet-spun into a coagulating bath of 55% aqueous nitric acid to form filaments, which are washed with boiling water and stretched to 5:1 in ethylene glycol at 140‹ C. The stretched fibres are then heat-set at 160‹ C. (6) A methacrylonitrile-vinyl pyridine copolymer is dry spun as in (4), stretched to 8:1 on a heated plate at 140‹ C. and heat set at 170‹ C. while permitting 10% shrinkage. (7) A dry-spinning solution as in (4) is dry-spun using a column having a temperature of 100‹ C. at the top and 70‹ C. at the bottom. The filaments were washed with methanol and dried, and stretched to 7:1 at 160‹ C., followed by heat-setting at constant length at 180‹ C.

Abstract: 1,232,008. Rotary positive - displacement pumps. A.C. NORTH. Aug.21, 1968 [Aug.23, 1967], No.38896/67. Heading F1F. A pump for a liquid, which may contain solids in suspension, has a rotor 32 with annular channels separated by a web 34, which contains an aperture 1 between inlet and outlet ports 38, 39 for the working fluid, a laminated piston 28 being slidingly lodged in liners 29 that are fixed to the rotor. The piston moves axially while revolving with the rotor between annular cams 12 that are attached to stator end-walls 30, 31 and engaged with the channels. The working fluid flows to the port 38 through apertures 15 in a bearing 14 and a chamber 6 in the rotor. The fluid issuing from the port 39 is discharged through a divergent bore 22 in a casing 47. The cams may be made of a plastics material and are replaceable when worn. A mounting bracket 27 permits fixing of the pump in any one of several positions at 45 degree intervals about the axis of a driving-shaft 35. A second embodiment, Figs. 3 and 4 (not shown), is adapted for pumping a liquid containing solids in suspension and therefore differs largely in that the chamber 6 communicates directly with a fluid passage in a flanged extension 13 of the wall 30, the bearing 14 being omitted. To facilitate mounting of the pump with the shaft 35 vertical a thrust ring (20) for the rotor is attached to the wall 30. The shaft 35 may be extended through the wall 30 and form the rotor of a screw conveyer that directs the slurry into the chamber 6. The pump is basically similar to that disclosed in Specification 621, 522.
