Apparatus for separating two non-miscible liquids of different densities from a mixture thereof, including a vertical cylindrical tank with an inlet at one side and an outlet at the opposite side. External means produces a flow of the mixture into the inlet and of the heavier liquid through the outlet. The tank extends above and below the liquid-air interface to provide a free liquid surface inside the tank. A rotating impeller at the center of the bottom of the tank swirls the liquid in the tan...

A device for separating loose extraneous materials such as dirt, rocks, sand, soil and leaves from sugar cane stalks is a variable angle deflection chute and a series of pocketed rolls arranged in a slope inclined downwardly and upon which sloping deflection chute, the cane and extraneous materials is dropped to cascade on down the slope over the rolls. The pocketed rolls are power driven in a direction opposed to that of the cascading material. Spaced smooth rings of greater diameter than the p...

A settler type separating apparatus comprises a tank for holding liquid having inlet and outlet ports; a plurality of horizontally disposed particle-receiving trays superposed parallel on each other at prescribed intervals, each having a plurality of cavities formed on the upper side; and a screen stretched over the upper open side of the cavities of the tray, wherein impure particles trapped in said cavities are obstructed from escaping by a boundary layer formed by the screen.

A housing assembly for a separating medium disposed between upstream and downstream conduit members. The assembly comprises a first covering means communicating with the downstream conduit member. A first manifold means is spaced upstream from the first covering means and is connected at its upstream face to a first plurality of concentric cylinders. A second plurality of concentric cylinders are disposed in the annular spaces formed by the first plurality of concentric cylinders. This second pl...

A mixture of chemical substances such as optical isomers, geometrical isomers and polymers having different molecular weight ranges is separated to each ingredient by use of a cellulose derivative having an aromatic ring in the chromatographic method.

Apparatus for separating a mixture of materials into two categories such as potatoes and stones comprises a source of radiation such as X rays through which the mixture is passed, and detecting means responsive differently to the incidence of the radiation on the two categories of material. Directing means such as deflecting fingers, cause the material of the two different categories to be directed in different directions in response to the said different responses of the detecting means. The de...

Relatively long and therefore valuable textile fibers are separated from an air-borne mixture comprised of such fibers and of smaller particulate matter, such as shorter textile fibers, dust and the like, by a compact but highly efficient separating device of the centrifugal type. The device comprises a cylindrical housing having a diameter to length ratio of preferably approximately 1 to 1.1. Inlet and outlet ducts communicating with the housing are so positioned and proportioned that most of t...

An automatic feed device for postal franking machines includes a feed tray, a device for transporting mail on the feed tray and a drive of the transporting device. A separating head in the form of a structural unit includes brake levers separating mail and pressure rollers, holding-down devices and a manual actuating lever transporting mail. Guide shafts support the separating head during displacement of the separating head into a housing from an operating position outside the housing. A detent ...

An arrangement for separating a fluid comprising at least one liquid component and solid material particles. The fluid may also comprise gaseous components. The arrangement includes two adjacent liquids, between which a boundary surface is formed. By means of capillary force the boundary surface is non-horizontal. During separation the fluid comprising the solid material particles is transported by influence of the gravity force towards the non-horizontal boundary surface, through which heavier ...

A method of separating solid particles from the liquid constituent of a slurry, containing solids having a "wide" particle size distribution, that is, a size distribution wherein the equivalent diameter of particles in the slurry ranges between at least 15 microns and 150 microns. The method uses a screen bowl centrifuge and comprises: (a) establishing a bed of solids on the screen section of the centrifuge whose maximum radial thickness is greater than 15 times the mean particle equivalent diam...
