A process and an apparatus for the manufacture of finely distributed or colloidal mixtures of bodies insoluble in one another

... 286,316. Polanyi, M., and Bogdandy, S. von. March 4, 1927, [Convention date]. Emulsions, making.-Fine distributed mixtures of substances insoluble in one another are obtained by vaporizing or cathodically atomizing one substance, e.g. a metal, and condensing it in a vacuum on the surface of a liquid body of the other substance. The liquid is preferably continuously circulated at a high speed. A suitable apparatus comprises an evacuated container 1 for the liquid within which an inner vessel 13 is rapidly rotated. The liquid is drawn into the inner vessel by centrifugal force through radial passages 29 in the bottom thereof and escapes at the upper end by passages 36. The size of the passages can be adjusted by means of screws 34, 37 respectively. A rim 35 at the top of the vessel 13 ensures the retention of a liquid layer of appreciable thickness. The vapour of the substance to be dispersed enters the apparatus by a pipe 7 heated to prevent premature condensation and surrounded by a heat-insulating ...

Improvements in or relating to the production of colloidal dispersions

Colloidal dispersions are obtained by subjecting the material to be dispersed to a high potential with respect to a dispersion medium with which it is immiscible, the dispersion medium being separated from the material by an insulating partition having one or more minute orifices in it. Preferably the material is in the liquid state, e.g. molten metal or liquid alloy, and forms one electrode, a second electrode being immersed in the dispersion medium. The insulating partition may consist of a thin membrane of high dielectric strength, e.g. a cellulose acetate film, and may be punctured by a needle or by the application of a sufficiently high potential, or it may comprise a tube containing the material to be dispersed, provided at one end with a capillary tube which dips below the surface of the dispersion medium. According to an example, mercury is introduced into a cell and connected to a source of current. The surface is covered with a thin film of the dispersion medium, e.g. a semi-conducting ...
