Abstract: 1,263,696. Slip casting sheets. BRITISH ROPES Ltd. 15 April, 1969 [16 April, 1968], No. 17992/68. Heading B5A. [Also in Division C7] Sheets of sintered material such as Ni, SiO 2  and resins are formed by depositing the powder from a suspension of the powder in a liquid such as water, on to a permeable flexible support, e.g. cellulosic fibre mat controllably removing liquid particles from above the support during deposition and sintering the deposit. Wetting agents may be added to the liquid and the formed sheets may have a porosity greater than 60% and a thickness less than 0À005 inch. The porosity of the sheet can be made to vary throughout the thickness by adjusting the sizes of the powders deposited at various stages. Alternatively the core of the sheet may be porous and the surface less porous and vice versa. As shown in Fig. 1 deionized water is deaerated in container 4 and transferred to deposition chamber 9 via line 24. The base of chamber 9 consists of a detachable plate 12 supporting a diaphragm 15 of, e.g. porous sintered bronze or a plastic, on which is located the support web or mat 17 of cellulosic fibres. The base-plate is clamped to the chamber 9 by screw columns 16 and screw 14. The powder to be deposited is introduced into the water in chamber 9 via a feeding unit 26 which in a given time cycle adds selected increments of powder. After allowing sufficient time for the deposition of the required layer thickness on support 17 water and powder fines are withdrawn via outlets 19 and 22 under vacuum and when the level falls below 19, outlets 20 and 21 are opened. The base of chamber 9 is then withdrawn and the deposited layer on mat 17 is pressed, e.g. by rolling, removed from mat 17 and sintered between carbon plates in a neutral or reducing atmosphere. Figs. 5 and 6 (not shown) show different types of deposition chamber 9 and Figs. 7 and 8 (not shown) show a more sophisticated arrangement for automatically feeding the powder into the deposition chamber via a measuring device. The automatic arrangement is operated electrically by switches and timing devices.

Title: Improvements relating to the manufacture of chlorides of ortho-hydroxy-carboxylic acids of polynuclear hydrocarbons
IPC: C07C51/60
Filed: 1926-07-20
Abstract: 278,463. British Synthetics, Ltd., and Higgins, E. B. July 20, 1926. o-Hydroxycarboxylic acid chlorides of polynuclear aromatic hydrocarbons are obtained by bringing thionyl chloride into intimate contact with inorganic salts of the acids. In an example dry, powdered monosodium salt of 2 : 3-oxynaphthoic acid is treated with the theoretical quantity of liquid thionyl chloride in a ball-mill. Sulphur dioxide is removed from the product by means of a stream of dry air and any unchanged thionyl chloride is decomposed by adding sodium or calcium carbonate. for example. This step is obviated, however, by using slightly less than the theoretical quantity of thionyl chloride. Magnesium and calcium salts of the polynuclear acids are also stated to be suitable in the process. The thionyl chloride may be used suspended in air or other inert gas and in the pure vaporous condition. The 2 : 3-oxynaphthoic acid may be used for the production of intermediate products for making azo dyesturfs according to the process of Specification 262,958.
