Title: Improvements in the treatment of materials made of or containing cellulose esters
IPC: D01F2/28
Filed: 1929-06-10
Abstract: 313,404. British Celanese, Ltd., (Assignees of Whitehead, W., and Dreyfus, C.). June 8, 1928, [Convention date.] Yarns and threads, treating with liquids.- Yarns, threads, &c. containing cellulose acetate or other organic esters of cellulose are saponified by treatment with an alkaline saponifying agent in the presence of alcohols, other than methyl and ethyl alcohol, which are swelling-agents for the esters. Alcohols containing more than one hydroxy group are preferred. By this method uniform saponification is secured, and although the product may be only partly saponified yet it still retains its selectivity as regards dyestuffs, cellulose acetate, for example, resisting the cotton colours while retaining its affinity for the dispersed dyestuffs although the solubility of the material has been changed by the treatment; the tensile strength, elasticity, handle, appearance, and water-absorbent properties may at the same time be improved; the treated cellulose acetate &c. material exhibits an improved resistance to hot treatments such as ironing. Suitable saponifying-agents are caustic soda and alkali alcoholates. The alcohols, with or without the addition of water, may be adopted as the solvent for the saponifying-agent; if the latter is an alcoholate it may be formed by adding metallic sodium or potassium to the alcohol. The materials may be immersed in a bath containing the saponifying and swelling agents; or the latter may be sprayed on to or passed into the materials. The amount of saponifying-agent may be less than that theoretically necessary. A pretreatment with other swelling-agents may be given. The Specification as open to inspection under Sect. 91 (3) (a) mentions also the use as saponifying-agents of ammonium hydroxide, barium hydroxide, and alkali carbonates, and as swelling- agents of methyl and ethyl alcohols; it also states that the process is applicable to the denitration of nitro-cellulose. This subject-matter does not appear in the Specification as accepted.

Filed: 1944-09-21
Abstract: 581,625. Furnace hearths and walls. SOC. ANON. POUR L'INDUSTRIE DE L'ALUMINIUM. Sept. 21, 1944, No. 18064. Convention date, Aug. 23, 1943. [Class 51 (ii)] [Also in Group XI] In a furnace for the electrolytic production of aluminium, the hearth is formed by pouring into the furnace shell an artificial carbon mass 1, e.g., ground coke with a binder of coaltar pitch, and then baking it. The carbon mass may be subjected to mechanical vibrations of high frequency as described in Specification 561,496 either before, during or after pouring. The baking is effected by passing a current through the mass 1 between metallic conductors 2 fixed in the furnace bottom and the carbon anodes 4 which are afterwards used for the electrolysis, conducting pieces 3, formed of artificial carbon masses already baked, being arranged within the mass 1 in contact with the conductors 2 and with their upper surfaces just below the surface of the mass 1. To protect the anodes 4 from oxidation, the spaces between them are filled in with granular alumina or powdered coal 5 which is removed after the baking is complete. The baking is carried out slowly, the current intensity being gradually increased up to the value normally used for the electrolysis. The side walls of the furnace may be formed in a similar manner with the use of a template, the carbon mass in this case preferably having its electrical conductivity reduced by the admixture of alumina or residues from the carbon lining of old furnaces.

Abstract: 496,073. Weighing -apparatus. WILLIAMSON, G. E., FITZGERALD, F. C., and VANDOME & HART, Ltd. July2,1937, No. 18482. [Class 143] Relates to a weighing-machine of the kind wherein a movable dial plate displays majororder numerals through apertures in a fixed graduated dial over which the pointer moves, and consists in providing means for limiting the movements of the steelyard or beam to correspond to the weighing range indicated by the movable dial plate, and for altering the position of the limiting means when the movable dial plate is adjusted to alter the weighing range. As shown, the weighing platform is connected by linkage 2 to the steelyard or beam 3 the movements of which are limited by cams 6, 7. In the position shown, the cams restrict the movement of the steelyard to the lowest weighing range, viz. from 0 to 5 cwts. the appropriate numerals being displayed through the apertures 30 in a graduated dial plate 8. If the load exceeds 5 cwts. the steelyard comes against the lower cam 7 and the pointer is arrested in the gap between the zero and 5 cwt. numerals thus indicating that the weighing range requires adjustment. The weighing range may be changed to weigh between 5 and 10 cwts. by rotating the cams 6, 7 by a handle 14, the cams being interconnected by gearing 12, 13. A Bowden wire connection 19 between the cam 6 and movable dial plate 9 changes the numerals at the apertures 30, and at the same time an auxiliary weight 15 is lowered by an arm 17, on to the steelyard to compensate for the gap between the maximum and minimum readings of the dial. The second revolution of the pointer then indicates within the range from 5 to 10 cwts. In a modification, the dial plate 9 instead of being rotatable is fixed and the numbers on the dial plate are obscured by opaque windows in the graduated dial until the appropriate numerals are illuminated by lamps controlled by the capacity-changing mechanism.
