    Abstract: An extruder has a barrel extending from a feed inlet end to an extruder outlet end. The barrel has an inner surface, an outer surface, and a wall thickness between the inner and outer surfaces. The extruder also has at least one heating member positioned provided on the barrel; a screw drive motor drivingly connected to a rotatably mounted screw positioned within the barrel, whereby the screw is rotatable at various revolutions per minute (RPM); and a controller is operably connected to the screw drive motor to adjust the RPM of the screw based upon a temperature of material passing through and/or being extruded from the barrel. Methods for operating an extruder filling a mold are also provided.

    Abstract: A vacuum cleaner has an upstream cyclone cleaning stage and downstream cyclone cleaning stage comprising a plurality of downstream cyclones in parallel and positioned in the air flow path downstream of the upstream cyclone cleaning stage. Each of the downstream cyclones has an upper end and a lower end, the upper end having a cyclone air inlet and a cyclone air outlet. The downstream cyclones are arranged around a central opening and a plurality of air flow openings are provided in the bottom of the downstream cyclone cleaning stage whereby air travels from the openings to the cyclone air inlets at the upper end of the downstream cyclones and air enters the central opening after exiting the downstream cyclones.

    Abstract: A surface cleaning apparatus is disclosed having an upper portion mounted to a surface cleaning head, a portable surface cleaning unit mounted to the upper portion, an above floor cleaning wand removably receivable in the upper portion, and a wand lock having a locked position in which the wand is secured to the upper portion and an unlocked position in which the wand is removable from the upper portion. The upper portion may stabilize the wand when the wand is drivingly connected to the cleaning head. An electrified flexible air flow conduit may electrically connect the surface cleaning head to the cleaning unit.
