Abstract: 359,979. Roller-and-ring grinding or crushing mills. BABCOCK & WILCOX, Ltd., Babcock House, Farringdon Street, London.-(Babcock & Wilcox Co.; 85, Liberty Street, New York, U.S.A.) July 30, 1930, No. 22969. [Class 59.] A grinding mill having a plurality of rows of balls is provided with means for feeding material to the balls and for dividing the material so that each row of balls is fed independently of the others. The ring 12, driven by a spider 15 on a shaft 17, rotates the balls 11, 14, the upper ring 19 and lower ring 8 remaining stationary. The upper ring is pressed down on to the balls by plungers 22, under the influence of springs 23, and the rotating ring 12 is provided with ploughs 35. A cylindrical skirt 34 extends from the upper portion of the mill to a plane below the upper edges of the balls 14 and air, supplied to an inlet 7, raises the ground material to a conical separator 36 and thence to the outlet 5. Air jets may be provided outside the balls 11 to lift the ground material into the path of the air passing under the skirt 34. Material is fed into a shoot 28 and falls on to a rotating cone 29 and thence to the balls 14. The top of the cone is perforated with a pair of quadrant shaped sections 30 so that half of the material falls through these sections on to a second rotating cone 32 which feeds the balls 11, a fixed extension 33 of this cone preventing the escape of the material below the balls. The material ground by the balls 14 passes downwardly, meets the material ground by the balls 11, and is thrown up by the ploughs 35 into the stream of incoming air which carries off the fines, the coarser particles falling back and becoming further ground by the balls 11.

Title: Improvements in or relating to the preparation of haloacetic acids
IPC: C07C51/29
Filed: 1950-09-21
Abstract: Haloacetic acids are prepared by a process comprising oxidizing monohaloacetaldehydes which aqueous solutions of hypohalous acid and recovering the haloacetic acids formed.  The reaction temperature may be controlled by the rate of addition of the hypohalous acid and the desired product may be recovered from the reacted mixture by extraction with a water-immiscible solvent and distillation.  In an example aqueous hypochlorous acid is added to aqueous monochloracetaldehyde and the mixture is allowed to reflux.  The product is extracted with ether which is then evaporated to leave monochloroacetic acid.  Aqueous solutions of hypobromous or hypoiodous acids may be employed instead of hypochlorous acid solution and bromoacetaldehyde and iodoacetaldehyde respectively are oxidized to bromoacetic and iodoacetic acids.  Diluents such as ether, alcohol and benzene may be present.
