Abstract: 574,544. Explosives. WILLIAMS, V. H., WRIGHT, H. R., and IMPERIAL CHEMICAL INDUSTRIES. Ltd. March 5, 1941, No. 3007. [Class 9 (ii)] An explosive comprising a crystalline polynitric ester, solid at normal temperatures and desensitized by a liquid aromatic nitrobody which is rendered viscous by the presence of a proportion of nitrocellulose dissolved therein, is formed by mixing with the aromatic nitrobody a mixture of the crystalline polynitric ester and a nitrocellulose co-precipitated from solution in a mutual organic solvent by means of a precipitating liquid miscible with the solvent, the nitrobody and the nitrocellulose being such that the latter is gelatinized by the former. Examples of crystalline polynitric esters are pentaerythritoltetranitrate, erythritoltetranitrate, hexanitromannitol, ennea-hexitol hexanitrate, dipentaerythritol hexanitrate, anhydro-ennea-heptitol penta-nitrate, dulcitol hexanitrate and nitrosucrose. The liquid for precipitating the solid ester and nitrocellulose is advantageously volatile, such as acetone, but if not volatile it is displaced by a volatile non-solvent liquid which is subsequently driven off. Other solvents are methyl-ethyl ketone, ethyl acetate, ethyl lactate, nitrobenzene, and other precipitants are alcohol, petroleum ether and methyl alcohol. As the nitrobody, liquid mono-, di- and polynitro-aromatic compounds, hydrocarbons and mixtures are suitable. One example of the explosive is : pentaerythrite tetranitrate 74¢ parts, nitrocellulose 5 parts, liquid nitrobody mixture 20 parts, and chalk ¢ part.

Abstract: 658,668. Diversity receivers; valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. Feb. 4, 1949, No. 3137. Con. vention date, March 24, 1948. [Classes 40 (v) and 40 (vi)] A diversity reception system for frequency shift modulated signals, comprises means for producing the even harmonics of each of the signals received at separate points, means for selecting, limiting, and then separating the fundamental and second harmonic signals, which are passed through separate discriminators, the outputs from which are then combined so that the composite signal is unaffected by relative differences in phase and magnitude of the signals. Fig. 1 shows a frequency shift modulated system, in which incoming signals to spaced aerials 1 and 2 are amplified and converted by a double heterodyne process to audio signals within a band width f1, by receivers 3 and 4. These signals are applied to combiner 8, which produces a series of even harmonics for each of the two input signals and then supplies a combined output. Low-pass filter 9 rejects all harmonics above the second, and limiter 10 amplifies and then limits the output from filter 9. The output from limiter 10 is supplied to filter 11, which selects the fundamental frequency, discriminator 13 and rectifier 15, which supplies a D.C. voltage to control keyer 17 in accordance with the received signals. The output from limiter 10 is also applied to similar units 12, 14 and 16, which deal with the second harmonic component and also control the keyer 17. The arrangement is such that an output is obtained from the second harmonic channel, even if the received signals are such that the fundamental frequencies are 180 degrees out of phase. Fig. 2 shows the circuit of the harmonic producer and combiner unit 8. Even harmonics in each channel are produced by rectifiers 19 and 30, and rectifiers 22 and 33 prevent D.C. saturation of the transformer secondary. The outputs from pentode valves 28 and 39 are combined and applied to low-pass filter 9.

In a method of protecting the supporting arms of mixing tools against wear, especially in mixers for concrete and the like, protective members of wear-resistant material shield the leading face and at least part of the other side faces of the arms. As applied to a stationary-pan mixer, Fig. 1, wherein tools 17 are carried on resiliently and detachably supported curved arms 15, the arms are protected by an assembly of members slipped over the arm and clamped between the tools 17 and abutments 38. Each protective member, Fig. 2, comprises a part-annular element 21 of hard steel having a wedge-shaped leading face 23 and broad shoulders 25, 26, and a groove 28 to receive a resilient insert 30, Fig. 7, which abuts the next member of the assembly. The members may carry baffles (not shown) to deflect the materials during mixing; their leading edges may be arranged to overlap like tiles, Fig. 8 (not shown). The end members of the assembly may be adapted to the shape of their abutments and those on a curved portion of the arm 15 may be shaped suitably and numbered serially. Instead of being slipped over the arm they may be secured by interlocking dovetailmembers or by a spring or clamping screw, or by a bolt passing through the arm, or by welding, see Figs. 3 to 6 (not shown).
