Abstract: 574,017. Blasting fuzes ; projectile fuzes. LOUDEN, J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 8, 1941, No. 15794. [Classes 9 (i) and 9 (ii)] A delay-fuze element for blasting, demolition and projectile uses, comprises a tube 1 of metal or other material, e.g. glass or porcelain, the inner end of which is either closed by an end wall which, by grooving or other mechanical means, is made weaker than the cylindrical wall, or has a pinhole 2 normally sealed by a thin coating 3 of film-forming material of a water-proofing character, such as nitrocellulose or a plastic or similar substance. The tube is filled under pressure with (a) a charge 4 of a heat-detonable explosive, and (b) a charge 5 of delay-burning composition. Such loaded tubes may be separated from the priming composition of the main detonator by an air gap. In an example, the explosive charge 4 may be 0.10 grams of a mixture containing lead azide 68 per cent, lead styphnate 29 per cent and aluminium powder 3 per cent. The delay composition 5 comprises 0.18 grams of monobasic lead 4 : 6-dinitroresorcinate. Both charges are loaded under a pressure of 10 tons per sq. in. This tube is suitable for a bomb detonator. In another example, in which pressures of 22 tons are used for both charges, the charge 4 is as above, but the charge 5 is loaded in two portions, the first being 0.28 grams of a 70 : 30 mixture of potassium permanganate and antimony and the second 0.04 grams of a 64 : 36 mixture of potassium permanganate and antimony. The first portion is loaded in seven increments.

Abstract: 612,689. Telegraphones. RADIO CORPORATION OF AMERICA. May 30, 1946, No. 16490. Convention date, May 30, 1945. [Class 40 (ii)] In a telegraphone, the spools 12, 13 carrying the magnetic wire 11 are mounted side by side on a common axis in a detachable cartridge 10, the wire 11 passing from the spool 12 to the spool 13 over a guide-block 14 which engages the transducer 20 when the cartridge 10 is inserted into the recording and reproducing apparatus, the spool 13 being driven by a motor 7 having a tyred shaft 8 in frictional engagement with the rim of the spool 13. When most of the wire has been wound on to the spool 13, the wire comes into contact with a bracket 19 which displaces the spool 13 and the cartridge 10 so that engagement of the tyred shaft 8 with rim of spool 13 is interrupted. The wire may be rewound on to the other spool by withdrawing the cartridge and re-inserting it after rotation through 180 degrees. Uniform tension of the wire 11 between the spools 12, 13 is maintained by providing the outer side of each spool with a narrow rim 33 which is urged constantly into frictional engagement with the inner surface of the casing by a spring washer 34 mounted between the spools 12, 13. The outer face of each spool is provided with openings 31 which permit inspection, through window 32, of the quantity of wire on the spools, the speed at which they are driven being sufficient to ensure persistence of vision so that the quantity can be observed during rotation.

Abstract: 1,093,209. Analyzing by gamma-ray resonance. SOJUZNY NAUCHNO-ISSLEDOVATEISKY INSTITUT PRIBOROSTROENIA. April 15, 1966, No. 16521/66. Heading G1A. A method of determining an element, isotope or compound thereof in a specimen by the resonance absorption and scattering of gamma rays comprises the steps of: (1) measuring N#, the number of gamma quanta transmitted or scattered with the source and specimen oscillated relatively to one another so as to destroy the resonance condition for most of the oscillation period. (2) measuring No, the number with the source and specimen relatively at rest. (3) measuring Nb, the number with the source and specimen at rest and a filter removing substantially all the resonance component of the radiation from the source. (4) calculating #, proportional to the required determination from the formula: The required relative motion between source and specimen is provided by mounting the source on a bimorphous Piezo-electric element made of polarized lead zirconate titanate. For determining SnO 2  in a rock sample, the source comprizes Sn<SP>119m</SP>O 2  powder and the scattered or transmitted radiation is measured by a NaI(Tl) scintillator coupled to a photo-multiplier. The filter is made by compressing Sn<SP>119</SP>O 2  with an organic compound. A calibration curve is produced by measurements on reference specimens made by compressing different amounts of chemically pure SnO 2  with an organic compound without disturbing the lattice structure of the SnO 2 .
