    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.

    Abstract: A surface cleaning apparatus includes a floor cleaning unit and a portable surface cleaning unit. The floor cleaning unit includes a surface cleaning head, an upper section moveably mounted to the surface cleaning head between an upright storage position and a rearwardly inclined floor cleaning position, a charger having an energy storage member, and an air flow path extending from the dirty air inlet to a floor cleaning unit air outlet. The portable surface cleaning unit is connectable to the floor cleaning unit, and includes a portable surface cleaning unit air inlet connectable in air flow communication with the floor cleaning unit air outlet, a main body, an air treatment member, a suction motor, a handle and a capacitor. When fully charged, the energy storage member stores sufficient stored power to recharge the capacitor at least twice.
