  • Publication number: 20200232232
    Abstract: The present disclosure relates generally to an insulation-retaining sheet, e.g., for blown-in insulation, that includes an integral vapor-retarding membrane. In one aspect, the disclosure provides an insulation-retaining sheet including a sheet of mesh having an air permeability of at least 200 cfm per square foot; and one or more strips of vapor-retarding membrane, the one or more strips of vapor-retarding membrane being laminated to the sheet of mesh, the first side edge each of the strips of vapor-retarding membrane extending to the first side edge of the sheet of mesh, the second side edge each of the strips of vapor-retarding membrane extending to the second side edge of the sheet of mesh, wherein the insulation-retaining sheet has a plurality of open zones extending laterally from the first side edge of the sheet of mesh to the second side edge of the sheet of mesh in which no vapor-retarding membrane is laminated to the mesh.

  • Publication number: 20200188927
    Abstract: A system for processing material has a power supply and a machine having a hopper for receiving and passing material to an auger. The auger has a shaft with an axis about which it rotates, a helical flighting mounted to the shaft, pins mounted to the helical flighting, and paddles mounted to the shaft. The radial outer edge of the helical flighting is crenelated with periodic notches that form rectangular blades on the helical flighting. The pins are rotationally and angularly aligned with leading edges of the rectangular blades. The system may include a vehicle, such as a trailer, having first and second compartments separated by a partition. The power supply is located in the first compartment and has a power supply member extending though the partition. The machine is located in the second compartment and coupled to the power supply member.
