Abstract: A management device simultaneously clamps both the power cord and the vacuum tube of a floor preparation machine to appropriately direct the power cord and vacuum tube and protect from damage the power cord, vacuum tube cord plug and machine socket associated with the power cord and fitting associated with the vacuum tube.

Abstract: The temperature of the chamber housing a shot wheel of a shot blaster is controlled by positioning a fan exterior to the chamber that creates air flow across a mounting plate defining the chamber. The air flow created by the fan may also pass around the bearing surrounding the drive shaft that turns the shot wheel.

Abstract: The adverse effects associated with high temperatures and warpage of parts of a shot blaster are ameliorated by providing a telescoping sleeve and valve mount and an orifice adaptor to regulate the area of the flow path from a shot reservoir to a metering valve.

Abstract: A removable gas separation cartridge includes a housing having an inlet port, an outlet port, and a bed of adsorbent material. The cartridge is removable from an oxygen concentrator which separates oxygen from ambient air by using an absorption process.

Abstract: Disclosed is a method of providing oxygen rich gas. Oxygen is separated from ambient air with an oxygen separator in discrete pulses, one pulse at a time. The start of the pulse is synchronized with the beginning of an inhalation of a person. The oxygen rich gas in each pulse is separated from the ambient air in real time during a nitrogen adsorption step concurrent with each inhalation.

Abstract: A gaseous fluid pump includes a compression chamber, a plurality of pistons, a plurality of electric coils, and a magnet. The chamber contains at least one inlet and one outlet and a plurality of open volumes created by an inner surface of the compression chamber. The plurality of pistons are within the compression chamber and each piston containing a body with at least a first diametrically polarized magnet centered in the body such that the first magnet attracts or repels depending on the relative position of the first magnet. The plurality of electric coils wound around laminations on an outside of the compression chamber with each of the plurality of electric coils configured to create flux paths centered around each of the pistons when provided electricity to act as a polarizing motor stator. A second magnet is centered within the compression chamber between two of the plurality of pistons.
