Abstract: 133,105. Slocum, F. L. March 13, 1918. Ammonia; cyanides; cyanamides.-The production of cyanogen compounds from nitrogen and a carbide, such as calcium carbide, with or without a catalyst, and the production of ammonia from the product, is effected in one apparatus by a continuous series of operations. The apparatus described comprises a series of furnace chambers 2 each having end doors 3 and a top 4 with an outlet 5 for the gases passing through a trap 6. Extending from one end of the heating-chamber is a platform 9 for the charging- rack. The rack consists of a frame 10 comprising uprights 11, side pieces 12, and cross-pieces 13. The rack is provided with rollers 16 and carries perforated trays 17, which may be provided with a lining of wire mesh 18. The rack is moved into and out of the heating-chamber by means such as a ram. To carry out the process, the heating-chamber containing the carbide is filled with nitrogen under slight pressure and heated to 1000‹ C. When the reaction is effected, the product is allowed to cool in the chamber to about 450 ‹ C., and steam is passed in to produce ammonia, which is collected. The rack is then removed and the trays re-charged, or the temperature of the furnace chamber is raised to 850‹ C. to expel water and carbonic acid from the residue.

IPC: H04L27/04
Abstract: 134,045. British Thomson - Houston Co., (General Electric Co.). Oct. 29, 1918. Frequency, changing.-In frequency-changing systems for radio-signalling, wherein an alternating current of fundamental frequency is deformed by an iron-cored inductance 2, 3, the harmonics to be used being separated out, a con denser 4 compensates for the internal inductance of the alternator, a condenser 5 in shunt compensates for the inductance of the winding 2, and a condenser 6 for the inductance 7, so that when no current is used in the radiating system, the alternator need only supply sufficient energy to make up losses in the circuit. The antenna, is connected through the inductances 13, 9 to the inductance 7, and one terminal of the alternator is grounded. In order that current of fundamental frequency shall not circulate in the antenna circuit, the point 12 is arranged to be at substantially the same potential as the grounded connexion of the alternator. The condenser 5 offers low impedance to currents of harmonic frequency, and, with the inductance 7, protects the alternator. If even harmonics are required, the core 2 must be saturated by a direct current. Specification 7151/13, [Class 40 (v), Wireless signalling &c.is referred to.

Abstract: 149,794. Chatterley, C. A., and Goulding, C. A. May 28, 1918. Bottling.-In hand or mechanically operated machines for filling bottles and other receptacles, a spring-operated liquid-admission valve automatically opens when equalization of pressure takes place between the bottle &c. and the liquid container and automatically closes when equilibrium is destroyed. On inserting a bottle &c. into the hood h and raising it, a plunger b at the upper end of the filling-tube e is pushed up and engages the lower end of the rod d<3> of the airvalve d, thereby opening the valve and allowing air or gas to pass from the upper part of the liquid container to the bottle &c. The plunger is provided with a jointing diaphragm b<1> and a gasket b<3>, and when the pressure in the bottle &c. is equal to that in the container the liquid valve c is opened by means of a spring c<5> so that liquid flows down the filling-tube e into the bottle &c. A wooden floating valve d<2> may be provided at the bottom of the air-port d<1>. A rubber or cushion sleeve h<1> is interposed between the upper end of the hood h and the undenside of the cap b<4> which carries the air-tube f.

[Class 38 (iv)] [Also in Groups XIX and XXXVIII] The anode current and time controls of X- ray tube control gear are provided with repeaters which select from a stabilized voltage source voltages proportional to the logarithms of the current and time settings of these controls, the two voltages being applied in series to a voltmeter to indicate the product of the two settings. In the form shown, current and time controls 7, 8 are ganged to switches 5, 6 which select tappings 3, 4 of the secondary winding of a transformer 1 having a primary winding 2 fed from a stabilized A.C. supply. The voltages tapped by the switches are proportional to the logarithms of the values to which the controls are set and are applied to a meter 9 calibrated in milliampere-seconds. The centre portion 11 of the secondary winding may be untapped to allow zero deflection of the meter to correspond to the minimum useful product. Maximum deflection may coincide with the maximum product at which the X-ray tube is rated, the meter being protected against control settings in excess of this by an overload device 10. Under the latter conditions the meter 9 may operate to prevent energization of the X-ray tube.

IPC: C01B21/26
Abstract: 136,158. General Chemical Co., (Assignees of Scott, W. W.). Sept. 7, 1918, [Convention date]. Catalytic agents, preparation of; nitrogen oxides, catalytic production of by combustion of ammonia. - In the catalyst oxidation of ammonia to nitrogen oxides, the catalyst employed consists of a mixture of cobalt and aluminium oxides. The catalyst is preferably prepared by evaporating and igniting a solution of the mixed nitrates; but it may also be prepared by igniting the mixed sulphates, or by moistening the mixed oxides or hydroxides to form a paste and heating the mixture; and the catalyst may be deposited on a carrier such as pumice. The best results are obtained when the temperature to which the mixture of oxides is heated during the preparation of the catalyst, is lower than the temperature which would prevail in the catalysing chamber; thus if the latter temperature is from 650-850‹ C., then the catalyst should be prepared at a temperature between 360-650‹ C.

Title: Improvements in the dyeing of acetate artificial silk
IPC: C09B5/16
Filed: 1932-05-19
Abstract: Acetate artificial silk is dyed by treatment with aminoanthrapyrimidines or their substitution products.  Such dyes are prepared by treating heteronuclear amidated anthraquinones containing at least one amino group in a -position with formamide; diluents such as phenols, and catalysts such as boric or oxalic acids, may be present, and in some cases excess of formamide as a diluent is advantageous; heteronuclear mono- or dialkyl- or arylamino-a -aminoanthraquinones may be treated thus.  Or heteronuclear amidated-a -acylaminoanthraquinones are treated with ammonia or its salts, preferably in aqueous suspension under pressure; instead of ammonia formamide may be used giving in the case of acylamino-a -aminoanthraquinones--the acylaminoanthra-pyrimidines (cf. Specification 385,295) from which the acyl group is removed by saponification; if other acid amides are employed Py.C-substituted anthrapyrimidines are obtained.  Or aminoanthrapyrimidines containing a Py.C substituent are obtained from the appropriate anthrapyrimidones by treatment with phosphorus pentachloride; the resulting Py.C-chloro derivatives can be condensed with amino or hydroxy compounds to give further Py.C-derivatives, among which the Py.C-amino bodies may be converted via the diazo compounds into cyano, mercapto and other substituents.  The dyes are applied in the usual manner, for example in the presence of dispersing agents.  In examples the application of the following dyes to acetate artificial silk is described or referred to:--2-, 3-, 4-, 5-, 6-, 7-, 8- and Py.C - aminoanthrapyrimidines (orange to red shades) particularly the 4-amino derivative when purified by way of the oxonium sulphate salt,--and an amino derivative obtained by nitration and reduction; 4-and -5-methylamino-anthrapyrimidines,--and 5-g -propanolamino anthrapyrimidine; 4-amino-2- or 3- methyl--(from 1.4-diamino-2-methylanthraquinone and formamide), 4-amino-Py.C-methyl- (from 1.4-diaminoanthraquinone and acetamide), 5-amino-Py.C-methyl-anthrapyrimidines (yellow to red shades); 4-amino-Py.C-amino-, 4-amino- Py.C-methylamino- (from the Py.C-chloro body and methylamine), 4-amino - Py.C - dimethylamino - anthrapyrimidines (red shades); 4-amino-5-nitroanthrapyrimidine; 4-amino- 2- or 3- methoxy- (from 1.4-diamino-2-methoxyanthraquinone and formamide), 4-amino-Py.C-phenoxy- (from the Py.C-chloro body and potassium phenolate) 5-amino-4- and -8-methoxy- (from 1.5-diamino-4-methoxy anthraquinone and formamide)--anthrapyrimidines; 4-amino-Py.C-chloro-anthrapyrimidine (from 4-benzoylamino anthrapyrimidone by action of phosphorus pentachloride followed by saponification), and aminochloro derivatives obtained by chlorinating 5-chloranthrapyrimidine and treating the dichloro body with p-toluenesulphamide (followed by saponification) or aqueous ammonia.
