Abstract
A system, method and apparatus for material handling and more particularly for processing material from a source for use in a material forming apparatus which produces residue material. The system includes storage means, which stores a predetermined amount of materials for use in the apparatus; return means operating cyclically which returns the residue material from the apparatus to the storage means; and a supply means which supplements the residue material with materials from the source, and the methods relate to ways in which such a system can be employed. A unique diverter valve composed of two pieces of substantially rigid material with a hole through each piece forms a part of the system. The two pieces of material are held together with their holes aligned. A piece of slightly deformable plastic, occupying most of the space between the two pieces of rigid material, has an aperture through it which can align with holes in both pieces. The plastic leaves a sufficient space between the pieces of material so as to move freely. The slight deformability of the plastic allows it to seat tightly and provide a complete closure, especially in the presence of a differential pressure.
