Title: Improvements in or relating to the manufacture of hydrocyanic acid
IPC: C01C3/02
Filed: 1935-05-29
Abstract: Hydrocyanic acid is obtained by reacting a hydrocarbon with a gaseous compound containing nitrogen, e.g. nitric oxide, in the presence of a supported platinum-metal catalyst prepared by coating a refractory material with a reducible compound of the catalytic metal and then thermally decomposing the compound in the presence of a moving stream of a non-reducing gas.  The catalyst may consist of one or more of the metals platinum, palladium, rhodium, iridium osmium, or ruthenium supported on vitreous silica, rock quartz, dehydrated silica gel, crude silicon carbide (carborundum) or silica-alumina gel.  The thermal decomposition may be conducted in a moving stream of an inert gas such as nitrogen or argon or an oxidizing gas such as oxygen or air at a temperature preferably above 500 DEG  C. say 1100--1400 DEG C.  The actual decomposition may be conducted at below 1100 DEG  C., the catalytic material being subsequently heated to 1100--1400 DEG C. According to examples, (1) a mixture of nitric oxide, oxygen, nitrogen, water vapour and natural gas are passed downwardly through a vertical silica tube heated to 1100 DEG  C. and charged with a catalyst prepared by wetting 10 mesh vitreous silica or silica gel with an aqueous solution containing chloroplatinic acid and rhodium chloride, drying and heating to 1200 DEG  C. in a current of air; (2) a mixture of an ammonia oxidation gas and a fuel gas is passed at 1100 DEG  C. over a platinum-rhodium catalyst supported on vitreous silica, rock quartz, silica gel, carborundum or silica-alumina gel and prepared as set forth in example 1; (3) The process as set forth in example (2) is conducted employing as catalysts platinum, rhodium, platinumrhodium or platinum - palladium supported on vitreous silica and prepared as set forth in example (1).

Abstract: 650,693. Stuffing-box substitutes. ESCHER WYSS MASCHIIVENFABRIKEN AKT.- GES. June 18, 1947, No. 16083. Convention date, July 2, 1946. [Class 122(v)] In a means for sealing the pivots 2 of the blades 1 of propellers, hydraulic turbine and pump rotor wheels at the point where the pivot 2 emerges from the hub 3 which is filled with a lubricant under pressure and in which the pivots are mounted to rotate, each pivot is provided both with a packing 9 to prevent ingress of water and a packing 10 to prevent egress of lubricant and spaces 11 provided between the two packings of each pivot are connected to a common testing chamber 21. The spaces 11 communicate by borings 12, common annular groove 13, borings 14 and 15, annular space 16, and bores 19 and pipes 20, with the testing chamber 21. Oil is supplied from a reservoir 5 through a passage 6, an annular space 7 and a passage 8 to the interior of the hub 3. The contents, if any, of the testing chamber 21, drawn from a test cock 22 indicate, from their nature, whether the water packing 9 or oil packing 10 or both are leaking. In a modification, to enable a more selective testing, the space between the two packings for each pivot is connected to the testing chamber by a separate passage and by means of a hand pump, operated when the turbine is stationary, the contents of each such passage can be pumped out to give an indication of the state of its associated packings. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which a recess 46, Fig. 7 (Cancelled), between the water and oil packings 44 and 45 is connected by an oblique bore 48 to a radial bore 49 through the centre of the blade 41 and any packing leakage is thus pumped by centrifugal force, when the turbine is working, into the space 50 between the blade and the turbine casing 51. To avoid water pressure in the recess 46 when the machine is at rest a spring- loaded non-return valve may be fitted at the outer end of the radial bore 49. This subject-matter does not appear in the Specification as accepted.
