Patent GB-385516-A (GB)
Title: Method of manufacturing artificial silk
IPC: D01F4/00
Filed: 1932-05-23
Abstract: Artificial silk is obtained from silk fibroin or other albuminous material by dissolving it in a known solvent, adding an alkyl ester of an aliphatic or inorganic acid to the solution, and extruding the solution into a coagulant.  The addition of alkyl ester to the spinning solution enables it to be kept for a considerable time without loss of viscosity which would otherwise occur owing to decomposition of the fibroin.  The treated spinning solutions lead to the production of artificial silk which can be drawn out to a fine denier and which is of good strength and lustre.  In an example, a small proportion of ethyl acetate is added to a solution of copper hydroxide and nickel hydroxide in caustic alkali together with a small proportion of glycerin, glycol, tartrate, and sugar.  Natural silk fibre is dissolved in the solution which is then extruded through a nozzle into sodium bisulphate, ammonium bisulphate, or sulphuric acid to which has been added ammonium, sodium, or magnesium sulphate, or mixtures of these salts.  The filaments are subjected to stretching during the coagulating process.  If desired the ethyl acetate may be added after the fibroin has been dissolved.  Instead of ethyl acetate, there may be used methyl acetate, amyl acetate, propyl acetate; other alkyl esters of formic, oxalic, citric, tartaric, or acetic acid; or esters such as alkyl chlorides.

The control handle also adjusts the throttle through a separate hydraulic system. Gear change mechanism. Transmitter Fig. 1. The control handle 6 of a rotary switch is rockable from the neutral position, shown, to the left (ahead) to connect lines C, D, or to the right (astern) to connect lines A, C, over segmental contacts 8, 9, 10, and brushes 7, 7A, the lines B, C, being connected in the neutral position. Receiver, Figs. 3, 4. The. engine-gear-change mechanism is actuated to "ahead" or "astern" by moving a lever 5, from the neutral position shown, to the left or right through a crank 40, driven by a reversible electric motor 30 through gearing 31, 34, and shaft 3. The shaft 3 carries cams 13, 14, Fig. 3, cam 14 controlling switch contacts 15-18. and cam 13 controlling contacts 19-22. As shown, contacts 19, 21 are closed by the cam 13 to light pilot lamps indicating "neutral" and contacts 16. 18 are closed. Movement of the control lever to "ahead" e.g. connects lines C, D to energize the "forward" relay F which drives the motor 30 in a direction to drive the shaft 3 clockwise whereupon the cam 13 releases contacts 21 which open to extinguish the "neutral" lamp indicator and closes 22. When lever 5 has effected the engine gear change the cam 14 has rotated substantially 120 degrees when it closes contacts 15 to light the "ahead" lamp indicator and opens contacts 16 to stop the motor. Subsequent return of the control handle to "neutral" or to "astern" energizes the motor in the opposite sense until the circuit thereof is broken at the appropriate contacts by the cams 13, 14 as the shaft 3 reaches the corresponding position. The "astern" pilot lamp is controlled over contacts 17. Throttle control. The control lever 6 Fig. 1, actuates the throttle through a known hydraulic system and linkage Fig. 2 (not shown) so that the engine idles in neutral and is accelerated for either "ahead" or "astern."
