Abstract: Acylated amines are prepared by the hydrogenation of nitriles in the presence of acid amides, preferably in the liquid phase, at a pressure above atmospheric and/or at a temperature of 50--200 DEG  C. and using base metals or their compounds as catalysts.  A nitrile R.CN in the presence of an acid amide <FORM:0458454/IV/1> (R representing an organic radicle, X an organic radicle or hydrogen and Y.CO the radicle of a carboxylic acid) thereby gives rise to products R.CH2.NH2 and <FORM:0458454/IV/2> The nitriles specified are the same as those listed in the parent Specification and the same applies to the catalysts.  As amides the following are referred to:--formamide, acetamide, N-methylacetanide, N-amylacetamide, butyramide, N-propylbutyramide, caprylic amide, palmitic amide, benzamide, phthalimide and urea.  The products may themselves be employed as assistants in the textile and related industries or may be used in the preparation of such assistants or of pharmaceutical preparations. According to the example, lauric nitrile and acetamide are heated in an autoclave at 180 DEG  C. under a hydrogen pressure of 200 atmospheres in the presence of a nickel catalyst and N-dodecylacetamide separated from the product.  Reference is also made to the production of N-dodecylbenzamide by the hydrogenation of lauric nitrile together with benzamide at 180 DEG  C. under a pressure of 100 atmospheres in the presence of a copper-aluminium oxide catalyst.  Specifications 255,884, [Class 1 (i)], 356,731, and 421,718 are referred to.  The sample furnished under Sect. 2 (5) comprises N-monododecyl-urea prepared by heating lauric nitrile and urea in methanol solution in an autoclave at 70 DEG  C. under a hydrogen pressure of 200 atmospheres using a nickelchromium catalyst.

Title: Improvements relating to the filling of storage chambers for coal and other analogous solid materials
IPC: B65G11/20
Filed: 1933-09-29
Abstract: 424,661. Shoots. BLACKWELL, E. G., 18, Brickfields Road, Worcester. Sept. 29, 1933, No. 26823. [Class 78 (i)] [See also Group X] A helical shoot for loading coal or like pulverulent material into storage chambers is formed with successive portions having a reversed twist in order to minimize breakage in delivery. Figs. 1 and 3 show a pair of inclined shoots for filling the storage-chamber c. Each shoot comprises a section a<1> with a right hand twist followed by a section a<2> with a left hand twist, the remaining sections a<3>-a<5> having right and left hand twists alternately. The extreme end may be fitted with a screening-device. To maintain the coal in the helical path, the outer edge of the convolutions is formed with a flange e which is of maximum depth at the commencement of each section and tapers off towards the end of the section, finally being bent inwards as shown at f to direct the material to the succeeding section. The inclination of the shoots, coupled with the formation of the helical path, causes the point of deposit of the material to be varied laterally as well as angularly as the chamber fills, thus counteracting the tendency to form a cone of deposited material with consequent separation of the larger and smaller pieces. The shoots may be used in chambers having open-sided discharge orifices h screened by a number of bars g.

Title: Improved fuel
Inventor: GOUGH KENNETH JOHN
IPC: C10L1/18
Filed: 1954-09-21
Abstract: A residual vanadium-containing hydrocarbon fuel oil composition contains an oil soluble salt of a Group 2 metal and the acidic products obtained by the oxidation of a mineral oil fraction containing more than 10 per cent of waxes having between 28 and 32 carbon atoms.  The wax-containing fraction, which may be a foots oil or slack wax, is oxidized by blowing with oxygen or oxygen-containing gases, at a temperature between 100 DEG  and 200 DEG C., preferably in the presence of a catalyst such as manganese stearate and potassium permananate.  The salts are formed by reacting the acidic products with a Group 2 metal oxide such as magnesium oxide, at 150 DEG  to 200 DEG C., preferably in a diluent hydrocarbon, such as a heating oil fraction.  The salt is blended with the residual oil to give an atomic ratio of Group 2 metal to vanadium of between 1:1 and 10:1.  Examples are described.

Title: Coders for electric pulse code communication systems
IPC: H03M1/00
Filed: 1952-10-31
Abstract: 711,762. Pulse code modulation circuits. STANDARD TELEPHONES & CABLES, Ltd. Oct. 31, 1952 [Jan. 2, 1952], No. 27439/52. Class 40 (5) Binary pulse code groups are derived from a frequency-modulated carrier, by sampling the latter, feeding the samples to a plurality of mixers, one for each code digit, supplying the mixers also with the outputs of preselected ones of a plurality of heterodyne oscillators, and thus producing the appropriate code digit outputs, which are converted to code pulses corresponding to the sample frequency. In the embodiment described, sample signal amplitudes derived from an audio source 3, Fig. 1, in circuits 4, 7, 8 frequency modulate an oscillator 11, the output from which is converted to an intermediate frequency in mixer 13 fed from the oscillator 12, the frequency-modulated I.F. samples being applied to the five-digit coding circuit 2. The latter comprises a circuit 15, shown in more detail in Fig. 4, which produces simultaneous A.C. pulses at the inputs of those of the five digit circuits 20, 22 which represent the sample frequency on the code employed. Circuits 20 are provided to produce standard length A.C. pulses which are rectified in circuits 22 and distributed in time by the delay line 23. The pulses of the resulting code group, which groups are in the cyclic progression code, are regenerated to a constant amplitude by a single-stability trigger circuit 24 and may be converted to groups in the simple addition code, in known manner, by a double-stability multivibrator 25. The coder circuit 15 receives the frequency-modulated samples over conductor 28, Fig. 4, which forms one of the inputs of each of five mixer circuits 37 ... 41. In one example, the sample frequencies vary from 16 to 32 Mc/s and the mixer output circuits are shunted by resonant circuits 42 ... 46 respectively, tuned to 70, 71, 73, 77 and 81 Mc/s respectively and having bandwidths Œ 1/2, Œ 1, Œ 2, Œ 4 and + 4 Mc/s respectively. The other mixer inputs are selected from the outputs of eights oscillators 29 ... 36, generating waves of 53, 45, 49, 41, 51, 47, 43 and 39 Mc/s respectively. The first and second digit mixers 41, 40 receive the output from oscillator 29, the third 39 from oscillators 29, 30, the fourth from oscillators 29 ... 32 and the fifth from all the oscillators. In the case, for example of an input sample pulse of 24.7 Mc/s, this frequency combines in mixers 41 and 40 with the 53 Mc/s of oscillator 29 producing an upper sideband frequency of 77.7 Mc/s which is passed by circuits 46, 45 corresponding to digits 1 and 2. It also produces an upper sideband frequency of 69.7 Mc/s in mixer 37 with the 45 Mc/s of oscillator 30, which is passed by circuit 42 of digit 5. No sidebands produced bv mixers 38, 39 pass the circuits 44, 43 corresponding to digits 3 and 4.

Abstract: 535,309. Conveying billets, bars &c. TRIGGS, W. W. (Todhunter, W. J.). Oct. 12, 1939, No. 27748. [Class 78 (i)] Billets, bars, boxes &c. delivered by the roller table 22 are aligned by the end stop 20 positioned by the fluid pressure cylinder 20<SP>1</SP> and are then delivered by reciprocating pushers 23 to the loading table 26 which is lowered after the receipt of each batch so as to carry a number of superposed batches before they are removed finally. During the pushing stroke the articles are removed from the roller table on to tapered members 25 which support them during the remainder of the stroke. A counterweighted stop 38 yields on the initial impact of the bars at the end of the forward stroke but is restored by gravity as the pushers recede and moves the bars back into alignment with those layers previously delivered. A hand-operated wedge varies the extent of the restoring movement and thus provides for adjustment of the stop position of the billets. Members 29 are raised through linkage operated by the hand-lever 35 to abut against the rear of the layer of bars and retain them while the pushers are withdrawn.
