Title: Improvements in or relating to the purification of gases from hydrogen cyanide
IPC: C01C3/20
Filed: 1922-05-09
Abstract: Gases are freed from hydrocyanic acid with the production of ammonium sulphocyanide by treating the gas in the presence of sulphuretted hydrogen, ammonia, and water with calcium, barium, or strontium bicarbonate.  The gas, which must be free from air, may be passed through a solution of the bicarbonate, such as calcium bicarbonate, or may be brought into contact with the solid carbonate in presence of water and carbon dioxide, which, if not already present, are added to the gas.  The ammonium sulphocyanide is washed off the surface of the solid carbonate from time to time, e.g. by a spray of water. According to the Provisional Specification, magnesium carbonate or bicarbonate may be employed.

Abstract: 992,645. Automatic frequency control systems. SIEMENS & HALSKE A.G. April 5, 1962 [April 5, 1961], No. 13100/62. Heading H3A. In frequency control of a variable-frequency oscillator a voltage-controllable capacitor C3 is in series with the tuning capacitor C1 or the whole tuning circuit and a voltage controllable capacitor C3 in parallel with the tuning capacitor C1 or the whole tuning circuit, and both controllable capacitors C3<SP>1</SP>, C3 may be independently adjustable and varied as shown by a control voltage at A. Alternatively, Fig. 2, the tuning capacitor C5 and a padding capacitor C8 form one leg of a bridge whose other leg is formed by a capacitor C5 in series with only one voltage variable capacitor C7 and the bridge diagonally connected by a capacitor C9, which is non-conductive, i.e. the bridge balanced, around the mid-frequency of the oscillator frequency. The systems provide more linear frequency control. The voltage controllable capacity diodes may be replaced by reactance tube or transistor circuits, or by a capacitor in series with a diode whose duty cycle period of conduction is variably controlled.

Patent GB-125621-A (GB)
Title: Improved Method for the Manufacture of Ammonium Nitrate.
Inventor: TYRER DANIEL
IPC: C01C1/18
Filed: 1916-09-19
Abstract: 125,621. Tyrer, D. Sept. 19, 1916. Ammonium nitrate is obtained by double decomposition between approximately equivalent quantities of ammonium sulphate and sodium nitrate, the reaction mixture being boiled to precipitate most of the sodium sulphate (i.e. until the boiling-point rises to 120‹ C.); the sodium sulphate is filtered off hot and washed with a. saturated solution of sodium sulphate and then with water; the ammonium nitrate solution, preferably after a small addition of water, is then treated with a salt of a metal forming an insoluble sulphate, such as calcium or barium nitrate or chloride, so as to convert a part of the remaining sodium sulphate into a more soluble salt; the calcium sulphate &c. is filtered off and washed; and the ammonium nitrate solution is concentrated until its boiling-point is about 120-125‹ C., and cooled to effect crystallization, which takes place at from 35-15‹ C. The ammonium nitrate crystals are washed in concentrated ammonium nitrate solution and dried at 100‹ C., and may be purified by recrystallization. The mother-liquor is used, after .addition of water, for dissolving fresh ammonium sulphate and sodium nitrate. The first washings of the sodium sulphate, when enough ammonium nitrate has accumulated, are boiled to precipitate sodium sulphate and filtered, and the filtrate is added to the principal motherliquor. The washings of the sodium sulphate with water may be used as the saturated solution in subsequent operations. The washings of the calcium sulphate precipitate may be used to dilute the ammonium nitrate solution prior to the addition of calcium nitrate. The washings of the ammonium nitrate may be concentrated to crystallize out some of the salt, and the mother-liquor added to the principal mother-liquor.

Abstract: 133,171. August, J.. R. C. Oct. 9, 1918. Treating land and soil with flame; motor implements; adjusting parts of implements; rotary drums, mounting; steering.-A machine for treating disintegrated soil with radiant heat comprises a frame 1, carried on steering-wheels 2 and driving-wheels 3, which supports a rotating cylinder 15 through which passes soil lifted by a share 7 and elevator 11 as the machine moves over the surface of the ground. The cylinder 15 is carried by spiders which are loose on a shaft 17 driven from the countershaft of the machine and provided with cutting- arms 23 at its forward end and breakers 25 spaced apart down its length. The breakers are formed with pivoted arms carrying hammer heads. The forward set of spiders supporting the cylinder are mounted on a sleeve 20 which is driven by bevel-gear from the countershaft in the opposite direction to that of the shaft. The cylinder, shaft, and associated parts are pivoted at their forward end and provided with a screw 28 and a handwheel 29 to adjust their inclination. A stream of radiant heat such as a flame produced by a jet 30 of gas and air is projected into the rear end of the cylinder so as to travel in the opposite direction to that of the soil. A non-rotating jacket 32 formed by two walls enclosing non-conducting material encloses the cylinder and the stream of heated gases, after passing through the cylinder, returns through the space between this jacket and the cylinder, baffles 38 being.provided on the outside of the cylinder. A hook 37 on the rear end of the jacket causes some of the heated gases again to traverse the cylinder. The steering-wheels 2 are carried by a fork provided with a screw-threaded pillar 44 forming the steering- axis. A nut 45 journaled in a bearing member 47 is mounted on the screw 44 and is solidly-keyed to a worm-wheel 46. A clutch member 48 operated by a hand-lever is adapted to lock the nut 45 to the pillar 44 when desired and so to cause the steering pillar to be turned when the worm-wheel 46 is operated from the ordinary steering-wheel. When the clutch is detached, turning the steering- wheel causes rotation of the worm-wheel and the nut 45 round the screwed pillar then raising or lowering the front of the machine and adjusting the depth of working. The air for feeding the burner is heated by being driven through the radiator of the internal-combustion engine 6 of the machine. In a modification, the soil is dug up by hand and thrown into a hopper feeding the rotating cylinder. Specifications 120,587 and 121,262 are referred to.

Title: Improvements in or relating to oxygen jet cutting machines
IPC: B23K7/00
Filed: 1949-05-20
Abstract: 659,224. Dividing by fusion. HANCOCK, L. J. May 20, 1949, No. 13531. [Class 83 (iv)] A profile oxygen-cutting machine comprises a cutter 9 and tracing mechanism movable together over a work-piece and a drawing respectively, wherein displacement of the cutter and tracing mechanism is effected by a steerable driver wheel 12 bearing on a cylinder 7, the steering movement being controlled by a steering device 15 positioned over a flat drawing table 2. An oxygen-cutting element 9 is mounted on the top carriage 8 of a double carriage machine having a table 2 for a drawing and a lower carriage 3 which runs on longitudinal rails 5 fixed to the main framework of the machine and which carries transverse rails 4 supporting the carriage 8. The lower carriage 3 is supported on wheels 6, one pair being coupled to the cylinder 7 of the same external diameter. The top carriage 8 carries a bracket 11 which supports the driver wheel 12 and maintains it in contact with the cylinder 7 so that when the wheel 12 is set with its axis of rotation at right-angles to the axis of the cylinder 7 the top carriage 8 is driven along the rails 4 and when the wheel 12 is turned about its vertical axis through a right angle it will rotate the cylinder 7 and thereby move both carriages along the rails 5. In intermediate angular positions of the driver wheel 12 the resultant movement includes components in both directions. A drive unit 13 provides for a bodily steering movement of a sleeve 14 which carries the wheel 12. The steering is controlled manually by following the drawing with a cross optically projected from a device 15 which is coupled by spur gears 17 to the sleeve 14 so that by rotating the tube to adjust the position of the cross, the wheel 12 is turned in the opposite direction at the same rate and to the same extent. Alternatively, a photo-electric tracer system of known type may be used. The cylinder 7 may be offset and gearing interposed between the cylinder and the wheels 6, but if the cylinder rotates in the opposite direction to the wheels 6 an idler wheel is inserted between the gears 17 to secure correct steering action.
