| 20080251426 | METHOD FOR THE SEPARATION OF OVERLAPPING DENSITY POROUS MATERIALS FROM LESS POROUS MATERIALS - Enhanced methods for separating of overlapping density porous materials are provided. The methods of the invention exploit the differences in the porosity of porous feed materials compared to that of the solid plastics. In the first stage, air is forced out of the pores of a porous feed material. In the second stage, a solution, having the appropriate density, is forced into the pores. This increases the density of the porous material relative to the density of the solid plastics. As a result, the porous material can be made to sink, while the solid plastics continue to float. | 10-16-2008 |

| 20100288680 | HEATING SYSTEM FOR MATERIAL PROCESSING SCREEN - A separation screen has multiple discs configured to receive a material stream at an in-feed end and move a first group of materials from the material stream up an inclined angle and over a top out-feed end of the separation screen while a second group of materials from the material steam either fall through openings between the discs while being carried up the separation screen or roll off the in-feed end of the separation screen. A heating system heats an outside surface of the discs so that the discs can separate the first group of materials from the material stream during cold environmental temperatures. | 11-18-2010 |
