    • A receptacle for secure mail and parcel receipt and storage. The receptacle includes a top which provides a roof for the receptacle, a base, and a housing connected to the top and the base. The housing includes an upper compartment into which mail is first placed, a lower compartment into which mail is deposited from the upper compartment, a front door, located on a front of the receptacle, which is opened to provide access to the upper compartment and through which mail is placed into the upper compartment, a trap door, operatively connected to the front door, in the upper compartment, and an access door that includes a lock. The trap door rests in an open position when the front door is closed, allowing communication between the upper and lower compartments. The trap door is moved to a closed position by the opening of the front door, thereby preventing access to the lower compartment from the upper compartment. The trap door returns to the open position when the front door is closed, depositing any mail placed in the upper compartment into the lower compartment. The access door is unlocked and opened to provide access to the lower compartment, whereby mail deposited and stored in the lower compartment may be retrieved through the access door.

    • A vacuum cleaner includes a cyclonic airflow chamber that facilitates the separation of contaminants from a suction airstream. The airflow chamber includes a chamber inlet and a chamber outlet, with the chamber inlet being fluidically connected with at least one of a suction nozzle and an above-the-floor cleaning tool. An exhaust filter housing includes a suction duct and an exhaust plenum, with the suction duct communicating with the chamber outlet. A suction source housing includes an open end communicating with the exhaust plenum and a closed end. A suction source is positioned within the suction source housing to define an annular exhaust flow passageway surrounding the suction source from the housing closed end to the housing open end. The suction source includes a suction inlet communicating with the suction duct and an exhaust outlet communicating with the housing closed end.
