Abstract: A centrifugal stirring apparatus for treating loose particles or workpieces, comprising a work vessel and a rotary stirring disc on the floor of the work vessel, is characterized in that at least two work vessels comprising stirring discs are arranged adjacent one another and connected with one another via a common overflow opening. The particles or workpieces to be treated may pass directly from one work vessel to the next through such overflow openings and finally exit from the last vessel.

Abstract: An apparatus and method for mixing two or more distinct fluids is disclosed, and which includes a housing, a sleeve fixedly mounted in the housing and defining a mixing chamber, and a rotatable mixing head having a grooved outer surface disposed in the mixing chamber. At least one of the fluids is fed radially through the sleeve and into the mixing chamber, so as to be sheared and highly dispersed in the mixing chamber by contact with the rotating mixing head. In one embodiment, the sleeve includes a plurality of distinct openings for permitting the passage of the fluid, and in another embodiment the sleeve is composed of a porous metallic material, with the pores of the material defining the openings for the passage of the fluid.

Abstract: An improved method and machine for reclaiming in an on-line configuration both oriented and unoriented film produced on an extrusion line, in general, and an improved means within an on-line reclaim system for transferring both virgin resin and chopped reclaim to an in-line extruder, in particular, are disclosed.

Abstract: An apparatus for effecting the continuous conversion of feathers, hair, and other keratinaceous material into usable products: including a first vessel, said first vessel being jacketed and capable of heating the material therein without subjecting it to pressure, and paddles disposed for violently agitating the material within the vessel while gradually traversing it therethrough; a second vessel, a pump interconnected between the two vessels and providing for the transfer of the now fluidized material from the first vessel and into the second vessel while preventing the escape of any second vessel pressure back into the first vessel, the second vessel being jacketed and capable of heating the fluidized and flowable material therein to elevated temperatures while agitating the same to effect its hydrolyzation, and another pump connecting with the outlet side of the second vessel to provide for continuous discharge of the now hydrolyzed material and some pressure while the second vessel continuously hydrolyze

Abstract: A process and apparatus for the continuous drying and/or granulating of loose material. Loose material is conveyed through a drying/treating horizontal container by the action of a gas stream, the gas conveying force being opposed by a lesser, mechanical force derived from mixing tools within the container.
