Title: Improvements in and relating to Retorts and Methods of Working the same.
Inventor: WEST JOHN
IPC: C10B1/06
Filed: 1916-12-09
Abstract: 113,981. West, J., and Wild, W. Dec. 9, 1916. Retort furnaces; charging and discharging.- A plant for the destructive distillation of coal &c. comprises a number of horizontal or inclined retorts a, each horizontally narrow in end-on section and enlarging towards its outlet, the material normally being unable to pass through automatically under the action of gravity. The retorts are heated at the entrance to a temperature high enough to carbonize an outer skin around the charge, thus facilitating the passage of the charge through the first portion of the retort and ensuring cohesion of the whole mass passing through the retort. The hot waste gases from the combustion chamber at the entrance to the retort are led round the middle zone k of the retort, and the exit end of the retort is used to heat the air travelling to the combustion chamber. The retorts are simultaneously charged and discharged by reciprocating pistons c which bear on the coal admitted from hoppers d. The exit end of each retort, or of each pair of retorts in a vertical plane, leads to a downwardly-extending chamber f from which a gas pipe g ascends.

Abstract: 1,158,027. Purifying synthetic diamond. ALLIED CHEMICAL CORP. 19 April, 1967 [21 April, 1966], No. 18080/67. Heading C1A. Synthetic diamantiferous material is recovered from a crude mixture thereof with non- diamond carbonaceous material which may be graphite by treating said mixture with an inorganic base which is an alkali metal hydroxide, carbonate or a mixture thereof at at least the melting point of this base and in a quantity sufficient to form a liquid fraction which comprises a melt containing said suspended diamantiferous material and a solid fraction which floats on the surface of the melt and comprises the non-diamond carbonaceous material, and thereafter separating the liquid from the solid and removing the suspended diamantiferous material from the liquid fraction. The solid fraction may be separated from the liquid by oxidation of the solid with a molecular oxygen containing gas. The diamantiferous material may be separated from the liquid fraction by dissolving the base in water. The proportion of non- diamond carbonaceous material in the starting mixture should preferably be not more than 40%, or alternatively a preliminary step of acid treatment may be necessary to reduce the non- diamond content to 40% or below. The amount of base used should preferably be at least equal to the weight of the starting mixture. The twofraction melt is preferably formed at at least 375 C. Suitable starting mixtures are those derived from the nitric acid oxidation of a crude diamantiferous material produced by subjection of a non-diamond carbonaceous material to shock pressures within the region of diamond stability. Minor quantities of refractory metals and siliceous impurities may be present in the crude synthetic diamantiferous material.
