Abstract:
A mixing segment for an extrusion apparatus comprises a shaft and a plurality of plow elements aligned along a helical path extending about a rotation axis of the shaft. Each plow element includes an outer peripheral arcuate ramp extending radially outwardly along the helical path from a root to an outer tip of the plow element. Methods of manufacturing a mixing segment and methods of manufacturing a honeycomb structure with an extrusion apparatus are also provided.
Abstract:
An adhesive composition contains a block copolymer hot melt adhesive and a vapor releasing vapor corrosion inhibitor mixed with the block copolymer hot melt adhesive, the vapor corrosion inhibitor being in the form of particles suspended in the adhesive composition, the particles preferably having a maximum dimension of less than about 30 microns. One improvement results from inclusion in the adhesive mixture of a titanium and/or zirconium containing coupling agent, either separately or as part of the VCI particles. Another improvement results from blending the adhesive mixture in a continuous process using for example a twin screw extruder. As a result, the adhesive mixture has better uniformity and superior viscosity properties during use.
Abstract:
A vertical mixer has a mixing chamber with a vertical auger rotatably mounted therein. The mixing chamber has a side wall and a floor. The side wall has an opening therein that includes part of the floor and is closable by a door. The door includes a segment that is part of the floor when the door is in a closed position. The auger is sized and shaped to partially extend through the opening when the door is open during part of each rotation.
Abstract:
The invention relates to a kneading machine which comprises a substantially cylindrical bowl for containing a mass to be kneaded and a pair of kneading tools rotatable within the bowl with the same direction of rotation, around two axes parallel to the axis of the bowl, so as to define two theoretical cylinders which are substantially tangent both to each other and to the circumferential wall of bowl. Each kneading tool comprises at least one arm which extends substantially on the periphery of the respective theoretical cylinder, so that each arm has an orbital movement around the respective axis of rotation. Each kneading arm is substantially straight for at least one part of its length and is parallel or slightly incline with respect to a generatrix of the respective theoretical cylinder. Preferably the rotations of the two arms are synchronize with each other so that the two arms pass substantially simultaneously at the area where the two respectively theoretical cylinders are tangent to each other.

Abstract:
An animal feed mixer includes a housing forming first and second chambers. An upper auger and a lower auger are mounted in one of the chambers and a rotor is mounted in the other of the chambers. The rotor includes a plurality of arm assemblies that are staggered with respect to one another, that overlap one another in length, and that have paddles affixed to the outer ends of radially extending arms.

Abstract:
A vertical mixer has plexi-glass sight windows located in a side wall of the mixing chamber. The windows extend generally vertically between a top and bottom of the mixing chamber and provide visual access to an interior of the chamber from outside the mixer.
