Title: Granulation and size-classification of solid materials
Inventor: BLOOM MARTIN S
IPC: G05D5/06
Filed: 1964-03-18
Abstract: 1,094,621. Automatic size control. IMPERIAL CHEMICAL INDUSTRIES Ltd. March 5, 1965 [March 18, 1964], No. 11429/64. Heading G3R. [Also in Division G1] In a granulation process in which granulated material is classified into different size fractions, the quantity of material in a measuring device containing one size fraction is compared with a reference quantity and any change in the relationship between the two quantities is automatically corrected by control of the granulation conditions. As applied to the granulation of calcium sulphate, calcium sulphate hemi-hydrate and a spray of water are supplied to an inclined granulation dish rotated by an electric motor, and the resulting granules allowed to fall through a transverse air stream so that they are deflected to an extent dependent on their size into five hoppers which thus receive granules in different size categories. The granules in two of the hoppers are each passed through an inspection chamber one granule deep to intercept X-rays influencing ionization chambers so as to measure granule-mass. If the difference between the two measurements exceeds a predetermined value it is effective through a reversible servomotor to adjust the angle of tilt of the granulation dish in the appropriate sense so that granulation time and hence growth is varied to equalize masses in the two hoppers. A thin plastic tape moves between the inspection chamber and the X-ray source and between the inspection chamber and the ionization chamber to remove dust and moisture and prevent fouling. The ionization chambers have aluminium windows and are filled with krypton. The Specification also refers to:- (a) separation by hot gases which also effect drying. (b) intermittent sampling of granule mass. (c) controlling rate of feed to or rate of rotation of the granulator and/or the position of the liquid spray. (d) control in dependence on a comparison between one size category and a reference instead of between two size categories. (e) application to blunger, drum or compaction granulation or prilling from a solution, melt or slurry. (f) application to fertilisers, cement, carbon black, metal or plastic.

Title: A new or improved process and apparatus for bending glass tubes or rods
IPC: C03B23/06
Filed: 1932-04-22
Abstract: 379,257. Bending glass tubes or rods. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent-Treuhand-Ges. fur Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin.) April 22, 1932, No. 11613. Convention date, May 6, 1931. [Class 56.] A process for bending glass tubes or rods consists in clamping a tube to a rotatable former of the desired shape, heating the tube from the point of clamping over its whole length until it is softened, and simultaneously winding the tube on the former which has been set in rotation. The tube may be heated by means of burners, but preferably a small electric resistance oven is used. In the construction shown, the former consists of a vertical wheel 2 formed in one piece with a pulley 3 of smaller diameter and mounted on a shaft 1. The wheel is rotated by means of a weight 4 attached to a rope 5 wound on the pulley 3. The upper part of the wheel passes through an electrically-heated oven 7, and rollers 9, 10 are provided to support the glass tube 8 which is clamped to the periphery of the wheel 2 by a clamp 11. As soon as the part of the glass tube inside the oven is softened, the weight 4 causes the wheel 2 to rotate so that the softened part of the tube is wound on the edge of the wheel and a new and rigid portion of the tube is drawn into the oven. The movement of the wheel continues with the progressive softening of the tube until the desired length is bent. The weight 4 may be replaced by a spring, or the rollers 9, 10 may be replaced by driven rollers, the forward pressure on the tube being sufficient to rotate the wheel 2. The former may be oval instead of circular in shape, or it may be formed as a cylindrical or conical helix. Glass helices formed on the device may be flattened into rings or spirals. The former, or the whole of the apparatus, may be enclosed in a heated housing in order to anneal the tubes as they are bent.

Abstract: 740,482. Oil gas generation. NORTH THAMES GAS BOARD. April 26, 1954 [April 27, 1953], No. 11623/53. Class 55 (2). Petroleum oil as vapour or atomized liquid preheated to at least 100‹ C. is reacted with steam preheated to at least 1100‹ C. in the ratio of between 1 and 6 lbs. steam to 1 of oil. Distillate. oils may be preheated to approaching cracking temperature (350‹-650‹ C.); residual oils may be preheated and atomized through the superheated steam on to the top surface of the heat transfer material in contact with which the steam is being superheated. The steam is preferably heated to above 1350‹ C. in indirect heat exchangers, e.g. packed regenerators or pebble heaters or in direct exchangers partly of heat-resisting steel and partly of ceramic tubes. Additional preheat may be provided by adding hot combustion products; thus some air may be added before the steam enters the preheater and an equivalent amount of fuel burnt in the heated mixture. Or air may be added to a part only of the steam which is mixed with the rest after combustion of the added fuel. In an example 5.8 lbs. steam preheated to 1360‹ C. per gallon of petroleum oil preheated to 350‹ C. produce a gas comprising H 2  56.0, C n H m  19.7, CO 9.3, CO 2  6.9, CH 4  6.3, C 2 H 6  1.3, and N 2  0.5 per cent.
