A cellulose pulp particle having the shape of a general prismatoid having two parallel bases, the pulp particle comprising pulp fibers in a wet laid pulp sheet form, one of the bases having an area that is equal to or greater than the area of the other base, the area of the larger base being equal to or less than 30 mmand equal to or greater than 8 mm, the height of the particle, the perpendicular distance between the bases, being equal to or greater than 0.9 mm and equal to or less than 5 mm.

Product to promote fluid flow

A composition comprising 10 to 50 wt % wood pulp fiber and 45 to 85 wt % thermoplastic polymer wherein the average dispersion of the fibers within the thermoplastic polymer composition is equal to or greater than 90% as determined by the Dispersion Test. The pulp can be bleached chemical wood pulp fiber.

Composite polymer

A composition comprising 65 to 90 weight percent kraft chemical wood pulp fibers and a thermoplastic polymer and a method of making the composition.

Polymeric composites

The barrier properties of a water soluble gas barrier material are improved if the material is blended with a nanoparticle calcium carbonate having a size of from 10 to 250 nanometers. The barrier material is on a substrate to provide a substrate with gas barrier properties. A layer of heat sealable material may be applied to the exposed surface of the barrier material. A method for making the barrier coated substrate is disclosed.

Barrier material

A cellulose pulp particle having the shape of a general prismatoid having two parallel bases, the pulp particle comprising pulp fibers in a wet laid pulp sheet form, one of the bases having an area that is equal to or greater than the area of the other base, the area of the larger base being equal to or less than 35 mmand equal to or greater than 8 mm, the distance between the bases being equal to or greater than 0.9 mm and equal to or less than 5 mm, the particle being treated with a material. In some embodiments the material can be a hydrophilic, hydrophobic or softening chemical or a film.

Method of making a barrier material

A silo unloader for comminuting and gathering silage from a bunk silo detachably connects to the forward end of a hydraulically operated agricultural vehicle. The silo unloader is also hydraulically operated via controls in the vehicle cab and includes a cylindrical drum rotatably carried between a pair of vertically oriented screw jacks. A pair of circular cutting teeth are positioned at either end of the drum and are rotatable therewith. The screw jacks are operable to rotate in synchronous and alternating directions with the drum being attached thereto via a pair of nut elements which are threadedly engaged to the screw jacks. As the screw jacks rotate in the clockwise and counter-clockwise directions, the nut elements and the drum travel downwardly and upwardly thereon, respectively.
