Title: Improvements in the production of yarns, fabrics, films, foils and similar materials of organic derivatives of cellulose
IPC: D01F2/28
Filed: 1934-09-11
Abstract: Formed filaments, yarns, foils, films, and similar materials having a basis of organic cellulose derivatives are esterified with liquid media comprising anhydrides of lower fatty acids dissolved in diluents with acidic catalysts, or comprising halides of lower fatty acids dissolved in diluents.  The processes of Specifications 448,816 and 448,917 are excluded.  The treatment increases resistance to water and to delustring, raises the safe ironing temperature, and alters the dyeing properties.  The affinity for dispersed insoluble dyestuffs is reduced. Differential dyeing effects are produced by dyeing with an S.R.A. blue dyestuff a fabric containing ordinary cellulose acetate yarn and the same yarn which has been subjected to esterification. Esterifying agents specified are acetic anhydride, acetyl chloride, propionic and butyric anhydrides, and butyryl chloride. The yarns may be rendered insoluble or much less soluble in acetone.  The yarns may be treated in hanks, on perforated bobbins, or as woven or knitted fabrics.  The diluent may have a swelling action or be inert towards the cellulose derivative. Diluents specified are benzene, xylene, a hydronaphthalene, kerosene, butyl or amyl ethers, or carbon tetrachloride.  The reaction may be carried out at low or increased pressure.  Acid halides may be used without catalysts or with basic catalysts such as pyridine, dimethyl aniline, methyl piperidine, or dimethyl hexylamine.  Acidic catalysts specified for use with anhydrides are sulphuric acid, phosphoric acid, sodium bisulphate, sulphuryl chloride, organic sulphonic acids, hydrohalide acids, and metallic halides such as the chlorides of chromium, cobalt, antimony, bismuth, copper, and mercury, and cupric bromide.  After the treatment the reagents may be washed out, neutralized, or evaporated.  The materials may be stretched, shrunk, or dyed prior to esterification.  The yarns may be impregnated with catalyst and dried before being treated with the reaction medium. The material to be treated may be of cellulose acetate, formate, butyrate, or propionate, or of methyl, ethyl, or benzyl cellulose, or of a cellulose ether-ester.  In an example, cellulose acetate hanks are treated with acetyl chloride in xylene.  In another example, cellulose acetate yarn is treated with acetic anhydride, benzene, and sulphuric acid as catalyst.  The yarn is washed in ethylamine-benzene solution to neutralize acid, then with benzene, and dried, or it may be dried at low temperature, then treated with a solution of sodium carbonate with turkey red oil or other emulsifying agent. Specifications 389,823, 438,584, 438,585, 438,586, 438,587, 438,655, and 438,656 also are referred to.

Abstract: 358,051. Supply systems. GENERAL ELECTRIC CO., Ltd. and ELLIS, G., Magnet House, Kingsway, London. July 2, 1930, No. 20094. [Class 38 (iv).] Selecting sources for service.-Supply to an essential circuit in a system comprising a number of supply sources in parallel is maintained upon failure of the power supply to the bus-bars by automatic selection of one of the sources still effective. The essential circuit 9, 10 is automatically disconnected from the bus-bars 5, 6 by the failure of current in the coil 17 of a contactor 11 and connected to a positive bus 18 and a conductor 50. Timing relays 25, 26 are energized by an auxiliary contact 16, such relays as are supplied from effective sources then tending to close in sequence. The first to close energizes a contactor 29, 30 to connect the positive terminal of the source to the bus-bar 18 and close a maintaining circuit at its auxiliary contact. Coil 24 of an auxiliary contactor 21 is then energized to connect a common negative auxiliary bus-bar 19, 15 to the conductor 50 ; the timing relays are deenergized at an auxiliary contact 23. When the supply to the bus-bars 5, 6 is restored the contactor 11 reconnects the essential circuit 9, 10 thereto but the selected source maintains the terminals 14, 15 in condition to supply the essential circuit immediately should the bus-bar supply again fail. Alternatively interlock contacts on the contactor 11 may cause the contactors 29, 30 to open when the bus-bar supply is operative. In a modification the contact 16 may be omitted with the result that one source will always be connected to the contacts 14, 15. In a further modification the contactor 11 and the auxiliary contact 23 are omitted and auxiliary contacts closed when the contactors 29, 30 are open are connected in series between conductors 51, 46 to control the timing relays, or these contacts may be replaced by those of a relay closing upon failure of supply to the essential circuit.
