Title: Improvements in or relating to the manufacture of waterproof non-detonating fuses
IPC: C06C5/00
Filed: 1947-08-15
Abstract: 631,143. Fuzes for blasting ; fuze compositions. ZENFTMAN, H., OWENS, R. D. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 15, 1947, No. 22707. [Classes 9 (i) and 9 (ii)] Relates to waterproof non-detonating fuzes, in particular safety fuzes, for blasting and like operations which comprise an extruded core in a protective covering. According to the invention, the core is of a homogeneous thermoplastic composition comprising nitropolystyrene with a nitrogen content between 9.4 and 14.4 per cent and a softening point between 60‹ and 200‹ C., pulverulent oxidising and reducing agents being uniformly distributed throughout. The proportion of nitro-polystyrene is such that the composition is extrudable between 60‹ and 200‹ C. and yet allows continuous propagation of combustion through the core. The preferred nitrogen content of the nitropolystyrene is between 11.0 and 14.4 per cent. A mixture of oxidising and reducing agents is worked with the plasticised nitropolystyrene in a Werner Pfleiderer machine to form the core composition, at a temperature between 60‹ and 150‹ C. and extruded through a cylindrical die, preferably at temperatures between 80‹ and 120‹ C. The core may be extruded to enclose an axial metal wire or textile thread. The oxidising and reducing agents may be a lead compound and silicon or barium peroxide and a reducing agent such as sulphur, silicon, magnesium, calcium silicide or ferro-silicon. Examples are given of fuzes made according to the invention having burning speeds between 96 secs. per yard and 408 secs. per yard. In these examples the nitropolystryene has a molecular weight of about 100,000 and a nitrogen content of 13.96 per cent and is plasticised with di-nitrotoluene oil in the ratio of 40 : 60. Specification 616,453, [Group IV (a)] is mentioned as describing a process for the preparation of nitropolystyrene. Specifications 544,252, 580,409 and 610,069 also are referred to.

Abstract: 1468955 Cooking apparatus EAST CENTRAL STATE PROJECTS DEVELOPMENT AGENCY 23 May 1974 23026/74 Heading A4D [Also in Division B1] A machine 10 for use in the conversion of cassava pulp into garri comprises an elongate trough 12, a rotatable shaft 32 carrying blades 36 around its circumference and along its length, at least those blades towards an inlet 40 of the trough having holes (66) and at least those blades towards an outlet 38 of the trough being L-shaped when viewed in sections transverse to the shaft axis and thereby including flanges (68). The blades stir the trough contents and encourage it away from the inlet, where a predominance of cassava pulp flows through the said holes, towards an outlet, where a predominance of garri is carried around the rotating shaft by the flanges. Metal horizontal trough 12 is heated at its underside and has a sectional, vented cover. An electric motor 34 rotates shaft 32 on which the blades are arranged in a discontinuous helix overlapping each other in the shaft's axial direction and making an acute angle with the axis. If the trough is inclined the said angle may be zero. The angle is pre-set and the blade is sprung radially outwardly to scrape the trough. The areas of the holes decrease towards the outlet, the last blade having no holes at all. Flanges (68) cause, turbulence, aeration and cooling of the cassava pulp and throw it to one side of the trough, more pulp being thrown nearer the outlet because the flanges are wider, transversely to the shaft axis, on the blades towards the outlet. The cassava is thus gelatinized and dehydrated until dry garri is produced.

Abstract: 533,366. Cellulose derivative compositions. TENNANT, W. J. (Dow Chemical Co.). Aug. 11, 1939, No: 23231. [Class 2 (ii)] Cellulose derivative compositions comprise as plasticizer one or more substances of the general formula (R-O-R<SP>1</SP>)Xn wherein R R<SP>1</SP> are the same or different and are aryl groups, X is a cyclo-hexyl, dicyclohexyl, alkyl-cyclohexyl or aryl-cyclohexyl group, and n is a. numeral from 1.5 to 6 indicating the average number of hydroaromatic groups per molecule of plasticizer substituted in the aryl ether group. R R<SP>1</SP> may be phenyl, alkyl phenyl, aralkylphenyl, or naphthyl radicals or halogen substitution products of such radicals. The amount of plasticizer may be from 5 to 100 parts per 100 parts of cellulose derivative. The plasticizers may be prepared by condensing cyclohexene, an alkyl cyclohexene, cyclohexylcyclohexene, or aryl cyclohexene with a diaryl ether. The products obtained consist of mixtures of cyclohexyl diaryl ethers. Specified plasticizers are cyclohexyl diphenyl ethers, phenyl-cyclohexyl diphenyl ethers, cyclohexyl chloro-diphenyl ethers, cyclohexyl mono-ptert.-butyl diphenyl ethers, cyclohexyl α-naphthyl phenyl ethers, di-(phenyl-cyclohexyl)- diphenyl ether, di-(3-cyclohexyl-cyclohexyl)- diphenyl ether, and di-(3-methyl-cyclohexyl)- diphenyl ether. The cellulose derivative may be a cellulose ester such as the nitrate, acetobutyrate, or acetopropionate, or a cellulose ether such as ethyl cellulose, benzyl, propyl, butyl, or amyl cellulose. In an example, the cellulose derivative employed is an /ethyl cellulose having 48.5 per cent. ethoxyl and a viscosity of 75 centipoises when dissolved to form a 5 per cent. solution in a solvent consisting of 80 parts of toluene and 20 parts of ethanol by volume. Films made of the compositions are of high tenacity. Some of the plasticizers, particularly those which are of a resinous nature impart considerable hardness to the compositions as well as a high degree of flexibility. The compositions have good electrical insulation properties and are resistant to the action of alkalies, and resistant to discoloration by detergents or exposure to light. The compositions may be used for making lacquers, coating compositions, or foils or for producing flexible tubing by extrusion. In another example, the composition contains high viscosity ethyl cellulose, stearic acid, and one of the specified plasticizers, and it is extruded to form a tough, flexible, waterresistant coating on a wire.

[Also in Division H3] An arrangement for measuring the moment of occurrence of an electrical pulse with respect to a moment of origin defined by a clock pulse has a first assembly of N identical coaxial cables 11 or striplines each receiving the electrical pulse and transmitting it with a delay greater than the pulse duration, and a second assembly of N coaxial cables 12 of different lengths simultaneously receiving the clock pulses and N tunnel diodes 8 each connected to a bias source and to one cable of each assembly so that a diode switches from one operating point to another if it receives pulses simultaneously from both assemblies. The diode which switches sends a pulse of well defined amplitude and duration along another coaxial cable 14 to a counter circuit (not shown) which responds only to pulses of that amplitude and duration. The tunnel diodes are matched to the coaxial cable through resistors 9, 10 and their bias current is less than the valley current, so that the circuit switches back to its initial state when the pulses cease. The assembly of N identical coaxial cables are connected in series to the input cable 17, and some delay may be included between them. The arrangement may be used for measuring time of flight of a sub atomic particle between a first point, at which the clock pulse is initiated, and a second point.
