Abstract: Apparatus for making a stable block from paper including means for providing a plurality of moist paper fragments, means for roughening the outer surface of a group of the moist paper fragments, and means for compressing the group of paper fragments to form the group of paper fragments into a stable block without the addition of an adhesive.
Abstract: A machine for cutting or slicing celery, carrots, or other elongate vegetables into pieces of selected size, accomplished on a rapid and highly economical basis. My machine utilizes a plurality of endless, moving belts, with one of the belts being arranged to receive vegetables deposited thereon, and to transport same to a location adjacent what may be regarded as the terminus of the belt. Mean such as other moving belts are utilized for gradually applying pressure to the vegetables during their travel along the length of the vegetable-supporting belt, thus to accomplish a compression of such vegetables into a tightly compacted mass. High speed cutter means operative adjacent the terminus serve to cut the vegetables into small pieces, with the size of the pieces being determined by the speed of the cutter relative to the velocity of the belts.
Abstract: Refuse is processed for land fill use by comminuting the refuse into smaller particles, blending the comminuted refuse to form an extrudable mass and continuously extruding the mass through a constricted die to form high-density, low-volume shapes which are suitable for burying in a land fill.Apparatus for carrying out the process includes at least one reduction mill, a blender having a shaft carrying radially extending pitched paddles for kneading and blending the comminuted refuse into an extrudable mass and an extruder carrying a constricted die and having a screw feed for continuously extruding the blended refuse to form high-density, low-volume shapes. The bore of the constricted die defines an outwardly tapered land adjacent the discharge end for controllably accommodating the normal expansion of the compressed refuse shape prior to leaving the die.
