Patent number: 11951486Abstract: 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.Type: GrantFiled: February 20, 2020Date of Patent: April 9, 2024Assignee: CERTAINTEED LLCInventors: Tony S. Piotrowski, Jack D. Coulter, Bruce A. Hartzell

Publication number: 20230330689Abstract: 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.Type: ApplicationFiled: April 12, 2023Publication date: October 19, 2023Inventors: Jeffrey Sacks, Pierre Lombard, Atchyutha Sreya Manju Bhamidipati, Michael J.
