Title: Process for the production of hydrocyanic acid
IPC: C01C3/00
Filed: 1950-10-12
Abstract: Hydrocyanic acid is produced in a continuous process comprising a first stage in which an alkali metal cyanide is formed at elevated temperatures, e.g. above 800 DEG C, from nitrogen and a mixture of alkali metal, e.g. sodium or potassium, carbonate and reactive carbon, e.g. wood charcoal, in the presence of an iron catalyst, e.g. metallic iron or an iron compound such as iron oxide, and a solid crystalline carbon-containing diluent powder, e.g. carbides of silicon, tungsten, or titanium, or preferably graphite powder, which at the temperature of reaction is infusible and inert to reactants and reaction products of both stages of the reaction, and a second stage in which the reaction product of the first stage is treated with carbon dioxide and steam to form hydrocyanic acid and reform alkali metal carbonate.  The mixture may be preheated and in the first stage subjected to electric heating at 950 DEG C in a rotary tube furnace in a counter-current of gas.  The carbon monoxide in the waste gas from the first stage may be burnt with or without an oxidation catalyst, e.g. copper or copper oxide, avoiding excess oxygen, and the carbon dioxide is used in the second stage while nitrogen is returned to the first stage; the heat from combustion of the waste gases may also be used in heating the first stage.  The mixture of carbonate, inert substance, and catalyst produced in the second stage may be returned to the first stage. p

Filed: 1949-10-03
Abstract: 693,894. Fluid-pressure servomotor-control systems. GARRETT CORPORATION. Oct. 3, 1949 [Feb. 24, 1949], No. 25354/49. Class 135 Mechanism for controlling the pressure in an enclosure such as an aircraft cabin 11 comprises a pressure sensitive element such as the diaphragm 22 subject to the pressure in the enclosure on one side and to the pressure in a control chamber 24 on the other side, the pressure within the control chamber being controlled by two pressure responsive means such as the bellows 48, 49 which operate on a single valve member 31 to control connections between the chamber 24 and a source of higher pressure such as the enclosure itself and between the chamber 24 and a region of lower pressure such as the ambient atmosphere. The bellows 48 is evacuated and responds only to the pressure within the chamber 24. The bellows 49 constitutes a differential pressure control and is subjected internally to the ambient atmospheric pressure through pipes 60, 34 and the cabin outlet 8. The bellows 48, 49 are anchored at one end to a cross member 26 and pivotally connected at their free ends to a lever 42. The lever 42 is pivoted to the stem 41 of the valve member 31 and its movement is limited by adjustable stops 55, 66. Each bellows is loaded by a tension spring 53 adjustable at one end by a screw 54 and connected at the other end to a lever 50 secured to the movable end of the bellows. Each of the levers 50 is pivoted on a fixed support 52. The valve member 31 is constituted as a piston valve with lands controlling ports 33, 35 leading to the atmosphere and the cabin respectively. Pressure is equalized on the two ends of the valve through grooves 38, 39 in the lands. The diaphragm 22 operates a cabin outlet valve 16 supported in a housing 12 formed as a unit with the housing 23 of the control chamber. Cabin pressure has access to the housing 12 through openings 13, 14. The valve stem 19 is supported at the end opposite the diaphragm 22 by a flexible member 20 comprising one or more spiral webs separated by slots 21. In the isobaric range, the bellows 48 rocks the lever 42 about the pivot 45 which is then fixed by the stop 66 whilst in the differential pressure range, the lever 42 is rocked by the bellows 49 about the pivot 44, then fixed by the stop 55. The tension of the spring 53 of the isobaric control may be varied gradually as described in Specification 650,766 so that the cabin pressure corresponds to the atmospheric pressure at a landing field by the time of the arrival of the aircraft there. The predetermined pressure differential maintained by the bellows 49 may be adjusted by the mechanism described in Specification 655,606. Specifications 521,623 and 693,959 also are referred to.
