Abstract: 302,280. I. G. Farbenindustrie Akt.- Ges. Dec. 13, 1927, [Convention date]. Coating -compositions; incorporating paint ingredients, special processes for.-Dope materials suitable for use in making artificial leather are obtained by intimately mixing a cellulose ester, a gelatinizing agent, a substantial proportion of an oil, e.g. an amount equal to that of the cellulose ester, a colouring matter or a filling agent, and, if necessary, other substances by working on a machine, such as on rollers under pressure, in presence of a volatile solvent (boiling below 100‹ C.), under such conditions of temperature that a large proportion of the solvent is evaporated, but without bringing the colouring matter into a colloidal condition. In an example, 100 parts of nitrocellulose, 100 parts of castor oil, 50 parts of camphor, 50 parts of lamp black, and 100 parts of alcohol, are worked on rollers heated to 60-80‹ C. under a pressure of 30-100 atmospheres for 2 hours, the alcohol being reduced to 20 parts. The product may be dissolved in low boiling solvents, if desired, with the addition of further oil, to form lustrous varnishes. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a similar method for making dope materials not containing oil, an example being acetyl cellulose, triacetin, or dimethyl phthalate, ochre and alcohol.

[Class 26] [Also in Group XXXVII] Refers to waste disposal apparatus for attachment to a sink, of the type comprising a waste receiving chamber with stationary shredding means located therein, a rotatable impelling reducing device mounted on a shaft driven by an electric motor and co-operating with the stationary means to comminute material from the chamber, passages in the chamber at the periphery of the rotating device for conveying comminuted material from the chamber, and means for supplying water for flushing the waste material down a drain pipe. The invention comprises a flow responsive member 34 carried on a shaft 36 and located in the discharge conduit 8, said member being biassed to extend across the discharge opening (as shown in full line in Fig. 1), and a cam 42 mounted on the shaft and adapted to actuate a switch 43 in the motor circuit to operate the motor 5 when the member 34 is moved away from the path of flow by the flow of water &c. through the conduit-thus ensuring the operation of the comminuting means as and when there is a flow through the apparatus. The member 34 is preferably dished, and when deflected by a flow of material to the position shown in broken lines, it rotates the cam 42 and arm 41 against the compression of an adjustable spring 37 to bring the flat of the cam in contact with the switch 43 and allow it to close. To ensure functioning, should the passages 30 become wholly or partially obstructed, bye-passing passages 44, 45 in the fly wheel 16 are provided (Figs. 2 and 3, not shown). U.S.A.
