    Abstract: A surface cleaning apparatus includes an air flow path, a cyclone bin assembly, and a suction motor. The air flow path extends from a dirty air inlet to a clean air outlet. The cyclone bin assembly is provided in the air flow path, and includes a cyclone chamber, a cyclone air inlet, a cyclone air outlet, a cyclone axis of rotation, and an axially extending cyclone chamber sidewall extending between first and second axially opposed ends. The cyclone chamber sidewall has first portion that is moveably mounted with respect to a second portion of the cyclone chamber sidewall between a closed position in which the first and second portions meet at a first juncture and a second juncture and an open position in which the cyclone chamber is opened. The first juncture extends at an angle to a plane that is transverse to the cyclone axis of rotation.

    Abstract: A surface cleaning apparatus has a first air flow path extending from a dirty air inlet to a clean air outlet with a suction motor and a cyclone positioned in the first air flow path. The cyclone has a cyclone chamber, a first airflow passage, and a second airflow passage. The first airflow passage defines a first tangential air inlet to the cyclone chamber and the second airflow passage defines a second tangential air inlet to the cyclone chamber. The airflow path includes a common airflow passage upstream of the first and second airflow passages and an axis of the common airflow passage intersects the cyclone chamber. At least a portion of the first tangential air inlet is positioned upstream from a location at which the common airflow passage axis intersects the cyclone chamber.

    Abstract: A hand vacuum cleaner has a first air treatment stage comprising a first stage air treatment chamber and a first stage longitudinal axis extending between the front and rear ends of the first air treatment stage and a second air treatment stage downstream from the first stage air treatment chamber, the second air treatment stage a second stage air treatment chamber and a second stage dirt collection chamber that is exterior to the second stage air treatment chamber. The second stage dirt collection chamber extends forward of the second stage air treatment chamber. A plane that is transverse to the first stage longitudinal axis extends through the first stage air treatment chamber and the second stage dirt collection chamber, and the first stage air treatment chamber and the second stage dirt collection chamber are concurrently openable.

    Abstract: A surface cleaning apparatus has a first air flow path extending from a dirty air inlet to a clean air outlet with a suction motor and an air treatment member positioned in the first air flow path. A second air flow path extends from an ambient air inlet to a secondary air outlet. An energy storage chamber having at least one energy storage member is positioned in the second air flow path. Ambient air can be drawn through the second air flow path to promote cooling of the energy storage members. A fan unit and/or an air foil can be used to draw ambient air into the second air flow path.

    Abstract: A molding apparatus includes a plurality of axially extending extruders. Each of the extruders is fluidly connectable with a common mold whereby the mold may be concurrently filled from each of the extruders. Each of the extruders has a feed inlet, and the feed inlets are axially spaced from each other. Another molding apparatus includes a plurality of axially extending extruders, and a heated conduit in flow communication with the extruders. The heated conduit is connectable to a mold, whereby the mold may be concurrently fillable from each of the extruders.
