Abstract:
Lasting albumose solutions are prepared by dissolving albuminous bodies in hot alkali and adding to the formed solution higher fatty acids or materials containing them, such as fats, for example cocoa fat, and substances to restrain the dissociation of the alkaline salts of the fatty acids, such as common salt, alcohol, or acetone. In an example keratine is dissolved in hot caustic potash and ammonia, and alcohol and ricinoleic acid are added to the solution.

337,239. Weidner, E. Dec. 12, 1928, [Convention date]. Delivery of articles stored in piles; delivery of liquids.-In a machine for delivering, after a single coin insertion, a piece of soap, a towel, and a liquid such as eau-de-cologne, disinfectant or the like, a handle 2, Figs. 1 and 2, is pulled, after prepayment, to actuate a slide 13 having an ejector 14 to push out a piece of soap 15 from a tube 16 to a dish 7, and a spring plate 18 to deliver a towel through an opening 9. The towels 10 guided by rods 19 have short under-folds 11 in which the plate 18 engages. They are downwardly inclined and rest at their rear ends on a cross bar 20. The opening 9 is normally closed by a shutter 46 opened by levers 47 which are actuated by projections 49 on the slide. A slotted arm 26 on a vertical arm 23 of the slide actuates the crank arm 28 of a three-way cock 29. At the end of the forward movement of the slide, the cook is turned to close the passage 31 between a tank 30 and a measuring tube 32, and establish communication between the tube 32 and a discharge pipe 33 leading to a tiltable bowl 5. When the slide is returned by springs 22, the pipe 33 is closed and the passage 31 opened. Coin action, weight.-A coin, having passed through the usual tester 51, drops down a shoot 52 and tilts a balanced beam 41 which engages one end 40 of a doubly cranked wire 38 and rocks this so that, its other end raises a pivoted toothed pawl 34 out of the path of a pin 35 on the slide. The coin is drawn along the beam 41 by the slide and rolls down a bevelled portion 45 to the money box 44.
