Title: Improvements in or relating to spinning
Inventor: BATES HAROLD
IPC: D01D4/04
Filed: 1955-06-22
Abstract: In melt-spinning artificial filaments from fibre-forming organic substances, the spinning is interrupted periodically and the spinning jet, which is made from an alkali-resistant material, is cleansed by immersion in molten sodium or potassium hydroxide, nitrite or nitrate.  The spinning jet may be a simple or laminated plate and may be made of stainless steel or nickel/copper alloy, e.g. Monel metal, Ferry metal or German silver.  The cleansing agent is preferably used at a temperature between 350 DEG  C. or its melting point, whichever is the higher, and 410 DEG  C.  The process is applicable to the melt-spinning of organic acid esters of cellulose and synthetic high-linear polymers, especially condensation polymers, e.g. polyamides (derived from adibasic acid and a diamine, or from an amine acid such as e -amino caproic acid), polyaminetriazoles, polyurethanes, polyureas and polyethylene, and is of especial advantage where the fibre-forming material has dispersed in it a small proportion of titanium dioxide or other inorganic pigment. Specifications 719,853, 719,860, 721,674, 748,772 and 796,771 are referred to.

Title: Improvements relating to the cooling of liquids to form powdered or granular solids,particularly soap powder
IPC: C11D13/20
Filed: 1925-07-17
Abstract: 250,441. Guttin, H. July 17, 1925. Spray, freezing.-Washing-powder is obtained from soap solution, or other liquid substances are solidified to form powders, by spraying the liquids in towers through which is passed a current of cold air exhausted from air-expansion engines performing external work. Atmospheric air may be mixed with the artificially-cooled air, to a regulated amount, before the air is admitted to the tower, and atmospheric air may also be admitted to the top of the tower to effect a preliminary cooling of the spray. The Figure shows a soap-making plant comprising steam-generators 1 supplying a steam turbine for driving an air compressor 3, from which the air passes through a reservoir 4 to an air-expansion engine 5 driving a dynamo 24. The soap solution is fed from a tank 16 by a pump 19 to the top of a spray tower 8, to which the exhaust cold air from the engine 5 is supplied through an attemperator 6 and chamber 7. Warmer air may be mixed with the cold air in the attemperator 6, and the mixture may be forced into the tower by a fan 13. Atrnospheric air may be delivered by a fan 27 to the top of the tower. The solid powder may be collected on a conveyer 9 and delivered by an elevator 10 and conveyer 23 to packing apparatus 15, 22.

Filed: 1931-06-29
Abstract: 390,476. Resistance coatings and deposits. PRELA GES. PRODUCTION ELECTROTECHNISCHER ARTIKEL, 117, Chausseestrasse, Berlin. June 29, 1931, No. 18697. Convention date, Sept. 23, 1930. Void [Published under Sect. 91 of the Acts]. [Class 37.] A high resistance comprising an insulating body of glass &c. on which a layer of graphite, carbon, metal, &c. is deposited has this layer made thicker than necessary, its thickness being subsequently reduced until the desired resistance value is obtained.' The reduction may be effected by grinding with sand, carborundum, &c. preferably in powder form. In the apparatus shown the resistance with lead-in wires or terminals, is held between clamps h connected to an ohm-meter o. The clamped resistance is then turned up by a lever i. During this turning-up, a flap f of a large container a opens and receives the resistance which at the same time comes into contact with driving gear g inside the flap, which is then again fastened. By the flywheel l, which is connected with a motor, the gear g is quickly rotated thereby rotating the resistance. The container a holds in its upper part a container for the reception of fine sand, pumice stone powder, &c. m, which is thrown upon the rotating resistance by means of an air jet d which can be regulated by foot and hand levers. The resistance layer is thereby ground away, causing the resistance value to rise. When the resistance is of the desired value, as indicated by the ohmmeter o, the air current is switched off and the lever i turned down again. The resistance is then removed and may be sealed into a small glass tube or surrounded by some other protecting cover.
