  • Patent number: 12214307
    Abstract: An air cleaner assembly is disclosed. In one aspect, the air cleaner assembly includes a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet. The air cleaner also includes a filter cartridge received within the housing and covering the access opening. The air cleaner also includes a lock mechanism. The lock mechanism is movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and lock mechanism include interacting features allowing the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.

  • Publication number: 20250031926
    Abstract: A vacuum cleaner including a top housing, a base, a suction source configured to generate a suction airflow, a tank positioned between the top housing and the base, and an actuator. The tank is configured to receive debris via the suction airflow. The tank includes an opening formed in an outer surface to the tank and a lid. The opening enables a user to provide debris directly into the tank, bypassing the suction airflow. The lid is moveable between a closed position where the lid fluidly seals the opening, and an open position where the opening fluidly connects an inner volume of the tank and a surrounding environment. The actuator is coupled to the tank and transitions the lid between the open position and the closed position.

  • Patent number: 9938662
    Abstract: This invention is directed to a process for treating biomass. The biomass is treated with a biomass swelling agent within the vessel to swell or rupture at least a portion of the biomass. A portion of the swelling agent is removed from a first end of the vessel following the treatment. Then steam is introduced into a second end of the vessel different from the first end to further remove swelling agent from the vessel in such a manner that the swelling agent exits the vessel at a relatively low water content.
