Abstract: 522,279. Controlling locomotives. WIENER LOCOMOTIV-FABRIKS AKT.- GES. Dec. 5, 1938, No. 35399. Convention date, Dec. 3, 1937. [Classes 79 (i) and 79 (v)] [Also in Groups XIII and XXVI] In a fireless locomotive employing a high accumulator pressure which is, throttled down to a normal working pressure; a compensating vessel 7 is arranged between the throttle 5 and the steam cylinders 10 and has a volume which is preferably a multiple greater than two of the spaces through which the piston moves. Two lower accumulators 1 are charged through valves 18, 19 and connected by line 20 with an upper evaporating vessel 2 from which steam is drawn off through pipe 3 and throttle 5 serving as the locomotive regulator, and then through superheaters 6 connected in paralled in all the tanks, or otherwise comprising a tubular coil preferably located in the upper tank. A steam piston may act to close the regulator when the pressure in the compensating vessel exceeds a maximum value. Throttle 5 may comprise an automatic reduction valve, the regulator being located between vessel 7 and the cylinders. Exhaust steam is utilized for the brake, pump whistle, train heating, or other auxiliaries, its pressure being increased by a steam jet compressor 15 supplied from a point b or direct from the accumulator. The compensating vessel may be located within a common insulation for the tanks or in the interior of the accumulator as by making the superheater so large as to provide the effect of a compensating vessel. In a modification, steam for the auxiliaries may be taken off from the compensating vessel, the connections being at the lowest point so that any condensate will drain off through the auxiliaries ; or saturated steam may be supplied to some of the devices. A throttled byepass direct from the accumulator may safeguard the supply when the main throttle valve is closed.

Abstract: 301,881. Oberrheinische Handels Ges, Dec. 7, 1927, [Convention date]. Void [Pub. lished under Sect. 91 of the Acts]. Fibres, treating; fibres, roughening mechanically. - Fibrous materials such as cotton, wool, artificial silk waste, staple fibres, and the like are curled and rendered more suitable for spinning purposes or for stuffing material, by treating with liquids and drying while in the loose state. Curling while moist in stamping machines, presses, centrifuges and the like and then drying further improves the spinning qualities. As moistening agents water may be used but better results are obtained by the addition thereto of soap, alkali, acid, oil, fatty acids, bleaching agents or other substances affecting the fibres chemically or physically. Drying in drums or other machines wherein the material is kept moving is an advantage. The sprinkling of powdered materials on fibres treated according to the present process further improves the spinning qualities.
