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.

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.

Temperature control for blast wheel housing

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.

Valve mount for shot blaster plenum valve

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.

Control of a self-powered floor preparation machine is provided by an ergonomic controller having a guarded control stick which has various characteristics, including its pitch, roll, yaw and height, that may all be adjusted.

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.

Method of separating and distributing oxygen

A method of controlling a fluid pump. The pump has a plurality of oscillating pistons that travel along a central axis of a piston sleeve. A plurality of pistons is of similar mass within a piston sleeve are provided, and adjacent pistons are positioned to be 180 degrees apart in phase oscillations. An electric coil is provided for each piston, and the position of adjacent pistons is determined. The current to one of the electric coils for a piston is adjusted to maintain the 180 degree difference in phase between oscillations of adjacent pistons.

Method of controlling gaseous fluid pump

A high frequency chest wall oscillation (HFCWO) therapy system includes an inflatable garment, an air pulse generator operable to produce oscillating pressure pulses that are communicated to the inflatable garment, at least one hose to interconnect the air pulse generator with the inflatable garment and to communicate the oscillatory pressure pulses from the air pulse generator to the inflatable garment. The air pulse generator is sized, shaped, and configured so as to occupy a volume no greater than about 1,200 in.and to weigh no more than about 17 lbs.

High frequency chest wall oscillation system

An apparatus for separation of gases from ambient air that has at least one separation column with an inlet at a first end and an outlet at a second end, a buffer column having a single inlet at a first end, a vacuum pump, and a valve system that connects the vacuum pump to the outlet at the first end of the separation column, and that connects the outlet at the second end of separation column to the single inlet at the first end of the buffer column.
