  • Patent number: 11951486
    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.

  • Publication number: 20230330689
    Abstract: The present disclosure relates generally to loose fill insulation installation systems, for example, suitable for installing loose fill insulation to an installation site. The present disclosure relates more particularly to a loose fill insulation hose including a plurality of tubular sections coupled together so as to form a conduit configured to convey loose fill insulation along a path from a blowing machine to an installation site. The tubular sections include a first hose section, a first connector section, and a second connector section. The first hose section includes a flexible body that forms an opening with a first cross-sectional area. The first connector section includes a plurality of projections that extend inward. The second connector section includes a constricted opening with a second cross-sectional area that is no more than 50% of the first cross-sectional area.

  • Patent number: 11668108
    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: 20220307640
    Abstract: The present disclosure relates generally to loose fill insulation installation systems, for example, suitable for installing loose fill insulation to an installation site. The present disclosure relates more particularly to a loose fill insulation hose including a first hose section, a second hose section and a first connection module including a first side attached to a distal end of the first hose section and a second side attached to a proximal end of the second hose section. The first connection module includes an interior surface including a conductive area. The loose fill insulation hose also includes a grounding wire electrically connected to the conductive area of the interior surface of the first connection module. The grounding wire is electrically isolated from the internal surface of the first hose section and the internal surface of the second hose section.
