Abstract: 865,206. Ammunition cartridges; explosive compositions. IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug. 3, 1956 [Nov. 9, 1955], No. 32098/55. Classes 9(1) and 9(2). A perforated propellant charge for a rocket comprises at least two concentric portions of propellent composition of substantially the same physical and thermo-chemical properties in cohesive union, wherein the end surfaces and the external surface of the charge are prevented from burning; each concentric portion has a slower rate of burning than its adjacent inner concentric portion; the configuration of each concentric portion is such that at any instant of time when the propellent charge is burning the sum of the products of the area exposed for each concentric portion and the rate of burning for that portion is such as to give a total rate of evolution of gas which is required for any desired pressure-time relationship; and wherein the burning reaches all points on the periphery of the charge at substantially the same instant of time. In the arrangement shown in Fig. 2 the inner fastburning propellant 7 is star-shaped and is provided with a star-shaped perforation at its centre; the slower burning propellant 6 fills the spaces between the inner propellant 7 and a cylindrical container. The dotted lines in the Figure indicate the intermediate burning position. The propellent compositions may each comprise 62 parts guanidine nitrate, 32À5 parts ammonium nitrate, 3À5 parts pottassium nitrate and 2 parts ammonium dichromate; in addition the faster burning propellant contains 0À2 parts cupric oxalate and 0À4 parts china clay, whilst the slower burning propellant contains 0À5 parts china clay. This gives a ratio of burning speeds of 1À25. In another arrangement, Fig. 3, the inner propellant 15 is provided with an elliptical perforation. The ratio of burning speeds in this case is 2À34.

Title: Improvements in or relating to the production of regenerated cellulose structures
Inventor: PONTIUS EUGENE CAMERON
IPC: D01F2/08
Filed: 1956-10-25
Abstract: Textile fibres and filaments and other structures of regenerated cellulose are made by partly xanthating alkali cellulose, adding to the resulting mixture a primary or secondary monoamine containing at least 2 carbon atoms but in which no radical attached to the nitrogen atom contains more than 8 carbon atoms, or a tertiary amine in which no radical attached to the nitrogen atom contains more than 8 carbon atoms but at least one radical contains an hydroxyl group attached to a carbon atom, and completing the xanthation, the amount of amine added being sufficient to provide not more than 1 millimol. per 100 grams of viscose.  Numerous suitable amines are specified, those soluble to the extent of 0.1% in 6% aqueous sodium hydroxide being preferred. The alkali cellulose may be prepared by conventional methods by soaking sheets of wood pulp or cotton linter cellulose in caustic alkali solution followed by shredding, and is then preferably partially xanthated by the addition of sufficient carbon disulphide to produce not more than 90% of the total xanthation. The partially xanthated alkali cellulose is then mixed with dilute caustic soda solution and the remaining carbon disulphide, and the amine is added either with the caustic soda solution, with the carbon disulphide or separately, preferably prior to or within twenty minutes after the start of the final xanthation step.  The resulting viscose preferably has a cellulose content of 4-10% and a total alkali content, calculated as sodium hydroxide, of 4-8%, and is preferably extruded at a temperature of 40-80 DEG  C. into an acid coagulating bath also preferably maintained at a temperature of 40-80 DEG  C. and containing 4-12% of sulphuric acid, 5-25% of sodium sulphate and 2-15% of zinc sulphate.  Other divalent metal salts, e.g. ferrous sulphate, manganese sulphate, nickel sulphate or chromic sulphate, may also be present in the bath.  The amine modifier or reaction products thereof carried over during spinning may also be present in the coagulating bath but the concentration thereof should not exceed 200 parts per million of nitrogen.  During their travel through the primary spinning bath the products may be confined to a small area by means of multiple rollers designed to apply tension to the travelling products in gradual increments and thereby orient them while still plastic, and they are preferably further stretched while passing through a shower or secondary bath consisting of water, dilute sulphuric acid or diluted coagulating bath, at a temperature of 50-100 DEG  C., to give preferred total stretches of 70-105%. Specifications 654,083 and 712,623 are referred to.

Abstract: 914,450. Lubricators &c. LORD MANUFACTURING CO. Sept. 14, 1961 [Oct. 17, 1960], No.32960/61. Class 12 (3). A device for lubricating the journal 2 in a railway car journal box 1 comprises a polymethane sponge body 7 with an oil impervious skin 8 which forms a container or oil reservoir and is located in the journal box below the journal. A wick 10 with pad 11 bears with its upper end against the underside of said journal and its lower end 14 fits snugly into a cavity 9 in the sponge body 7. The sponge body does not obsorb the oil and its cellular form permits oil to flow at a restricted rate into moulded chambers 19 in either side of the cavity 9 to where the oil may collect in sufficient quantity for absorbtion by the wick as required. The skin 8 provides oil retaining means together with the snug fit of the wick in the cavity 9 prevents loss of oil when the railway car may be inverted during a dumping operation. The oil level therein may be checked through a spout means or tube 20 integral with or cemented to the body 7. The resilient property of the sponge body provides pressure means to maintain said wicks in constant contact with the journal.

Abstract: 1,112,557. Hydraulic couplings. SMITHS INDUSTRIES Ltd. (Eaton Manufacturing Co.). 4 Aug., 1965, No. 33314/65. Heading F2C. A viscous coupling for driving a vehicle cooling fan has a working chamber 40 supplied with fluid from a reservoir 58 under the control of a bimetallic temperature-responsive coil, and has build-up of fluid in the shear space 56 formed between interdigitating projections 57 on an input rotor 11 and an output casing 12 delayed by notches 70 or slots formed in the cylindrical periphery of the rotor. The notches or slots serve to pump fluid from the shear space 56 to the opposite side of the rotor, whence it flows to the reservoir through ports 63 which are associated with pumping elements 66 fast with the casing 12. As shown, notches 70 are provided which get progressively narrower and shallower in the axial direction of the shear space and which are angled to assist the pumping action. As an alternative slots (Figs. 6-8, not shown) of uniform depth throughout the entire width of the rotor may be provided, the slots being suitably shaped and angled to promote pumping. The delay in build-up of fluid in the shear space retards acceleration of the output casing upon acceleration of the input rotor and thus causes fan noise, caused by acceleration of the fan, to lag behind, and thus be masked by, the engine noise. Cooling fins may be provided on the casing.
