Abstract: 208,281. Fairweather, W., (Singer Manufacturing Co.). Oct. 6, 1922. Gearing for stopping and starting machinery.- In power-transmitters of the treadle-controlled clutch-and-brake type used in sewing-machine power tables, the transmitter frame 11 has secured in it the spindle 13 on which are freely mounted driving and driven pulleys 16, 15 associated respectively with a driving clutch disc 14 and a driven leather ring 18. An arm 20, provided with a long boss 24 bearing on a spindle 25 secured by set-screws in an arm 27 of the transmitter frame, is actuated by a vertical treadle rod 34 and carries a cam-piece 21 contacting with a thimble 23 to put the clutch 14, 18 into engagement. A brake arm 29 having a pad 30 is clamped by its split hub 28 on a reduced part of the boss 24. By means of a nut 25<1> and collar 25<11> on the spindle 25, the clutch-actuating arm 20 can be adjusted. The reduced part of the boss 24 is longer than the hub 28, which abuts against the arm 27, so that the brake arm 29 is not affected by adjustments of the arm 20. A tension spring 31 connects the arm 29 to a lug 32 on the frame 11, the brake further being positively actuated on release of the treadle by an adjustable screw 41 carried in a depending lug 39 of the boss 24. The arm 29 carries also an adjustable stop 37 contacting with the arm 27 to prevent excessive depression of the treadle.

Title: Acetylene removal from hydrocarbon streams
IPC: C07C7/00
Filed: 1959-08-11
Abstract: In separating acetylenes from a butadienebearing hydrocarbon stream by contacting in a prewash stage with an aqueous cuprous ammonium acetate solution, butadiene is recovered from the aqueous solvent by contacting with a hydrocarbon stream; butadiene is recovered in the hydrocarbon while acetylenes remain in the aqueous solvent. Preferably the aqueous solvent is contacted with a C4 hydrocarbon stream containing less than 10% by weight of butadiene in a ratio of 0,1-1 volume of hydrocarbon per volume of solvent at 0-130 DEG F. and the resultant hydrocarbon phase is recycled to the prewash stage or is passed with the raffinate from the prewash stage to a butadiene extraction stage.  The aqueous solution is stripped of acetylenes and reused.  Specification 743,621 is referred to.
