Abstract: A hand vacuum cleaner has a cyclonic stage comprising an openable front wall provided at the front end of the cyclonic stage. A pre-motor filter is positioned in the air flow passage downstream from the cyclone air outlet and rearward of the cyclone sidewall. The pre-motor filter has a diameter in a direction transverse to the cyclone axis that is larger than a diameter of the cyclone air outlet in the direction transverse to the cyclone axis. The pre-motor filter has an outer perimeter defining a volume and the cyclone axis and the motor axis each extend through a centre of the volume. The cyclone axis is generally parallel to the motor axis. When the openable front wall is opened, the front end of the cyclone stage is opened and has an opening, the opening has a diameter in the direction transverse to the cyclone axis, and the rear end of the cyclonic stage has a diameter that is generally equal to the diameter of the opening.

Abstract: A data movement system is provided for moving data using a data-to-file-to-data movement path.

Abstract: Hydrophobic particles such as coal and hydrophobized mineral fines can be readily separated from hydrophilic impurities by forming agglomerates in water using a hydrophobic liquids such as oil. The agglomerates of hydrophobic particles usually entrap large amounts of water, causing the moisture of the recovered hydrophobic particles to be excessively high. This problem can be overcome by dispersing the hydrophobic agglomerates in a hydrophobic liquid that can be readily recycled. The dispersion can be achieved using specially designed apparatus and methods that can create a turbulence that can help destabilize the agglomerates in a recyclable hydrophobic liquid and facilitate the dispersion.
