Title: Improvement in ammonium salt production
IPC: C01C1/242
Filed: 1943-05-11
Abstract: 569,918. Ammonium salts. SEMET-SOLVAY ENGINEERING CORPORATION. May 11, 1943, No. 7491. Convention date, June 18, 1942. Drawings to Specification. [Classes 1 (ii) and 32] Ammonium salts such as ammonium sulphate, nitrate, phosphate and chloride are obtained in the form of large crystals by heating ammonia containing gases to a temperature of 30-60‹C. and raising their humidity to at least 70 per cent., passing the preheated and humidified gas beneath the surface of a body of solution in a saturator containing free mineral acid and an insufficient amount of ammonium salt to saturate the solution, withdrawing solution from the saturator cooling and concentrating the withdrawn solution to a condition of supersaturation by evaporation under vacuum, passing the supersaturated solution into contact with a suspension of crystals of the ammonium salt, which are thereby increased in size, recirculating the solution to the saturator, adding water and acid to the saturator in such a way as to prevent the concentration of the ammonium salt solution in the body of the saturator from rising to saturation, and effecting circulation of the solution within the saturator to prevent local supersaturation and crystal growth therein. Preferably the process is conducted so as to maintain a constant volume of solution in the saturator at a temperature of 45-50‹C. In the crystallisation stage the supersaturated solution may be passed upwardly through the suspension of, for example, ammonium sulphate crystals, the crystals which reach the desired size being removed from the bottom of the apparatus. The free acid in the saturator is preferably maintained at 1-5 per cent. The formation of incrustations above the liquid level in the saturator may be prevented by the introduction of exhaust steam. Specification 559,360 is referred to.

Title: Improvements in or relating to apparatus for ascertaining the weight of the fluid contents of tanks or reservoirs especially overground tanks
IPC: G01F23/18
Filed: 1935-03-14
Abstract: 437,706. Indicating liquid levels. SARUCHANOFF, N., 17, Giesebrechtstrasse, Charlottenburg, Berlin. March 14, 1935, No. 7919. [Class 123 (i)] Apparatus for ascertaining the weight of the fluid contents of tanks or reservoirs, especially overground tanks, comprises a U-tube 8 containing mercury and connected with the tank 1 and with a compressed air pipe 14 which is connected through a manometer 22 with the air chamber of the tank, a relief cock 6 and drain cock 11 associated with the U-tube, and a zero-adjusting device 12 comprising a scale and a vernier slide which may be set to indicate the zero level of the mercury. The vertical arms of the U-tube are replaceable. In ascertaining the weight of the contents of the tank above a zero level N, N, the zero level of the mercury in the right-hand side of the U-tube 8 is first determined by disconnecting the pipe 16 in order to open the pipe 14 to the atmosphere, opening a slide valve 3, valve 4 and relief cock 6. When the fluid flows from the relief cock the valve 4 and cock 6 are closed and the height of the mercury is regarded as the zero level, the vernier 12 being adjusted to this level. The pipes 14, 16 are now connected and the valves 4, 17 are opened to oppose pressure air from a reservoir 18 to the pressure from the tank. When the mercury has fallen sufficiently the valve 17 is closed. An exhaust valve 15 is temporarily opened to allow gradual escape of air until the mercury rises to the zero level previously indicated by the vernier 12. At this point the manometer 22 is influenced at one side by the gaseous pressure from the top of the tank and at the other side by both the gaseous pressure and the liquid pressure, that is the manometer indicates the liquid pressure in the tank. The weight of liquid may then be calculated by formula. In a modification, in order to arrest the escape of air through the exhaust valve 15 automatically when the mercury rises to the zero level, a conducting rod is arranged above the mercury so as to close an electric circuit and cause an electromagnet to liberate the exhaust valve when the zero level is reached.
