Abstract: The controller of the plural component proportioner (10) dispenses both components (or all three if a three component material) as necessary to maintain the correct mix ratio. The fluid displacement measuring technique described allows this proportioning to take place with the “A” or main component pump always able to supply fluid to the spray gun without being stopped. The “B” component, at a higher pressure, is added as necessary to control ratio. The control can determine whether the pumps were properly loaded with fluid, and the fluid was properly compressed for accurate measurement. This technique allows for the proportioned fluids to be provided to the spray gun(s) at high flow rates and consistent spray pressure without interruption.

Abstract: Various embodiments of the present disclosure provide a portable dunnage bag inflator that provides a compact, pressurized source of air and that is easily mounted onto a movable cargo mover (such as a forklift truck or a pallet jack). Generally, the portable dunnage bag inflator includes an impellor-driven blower that, in operation, draws air at atmospheric pressure through an air intake grid or air inlet into the impellor and expels the air through an inflation hose. Since the portable dunnage bag inflator includes an impellor-driven blower, the pressure of the expelled air is higher than atmospheric pressure. This enables dunnage bags to be inflated to the desired specifications at point-of-use (e.g., during or after loading of cargo into a cargo container) and eliminates the need for a compressed air supply.

The flexible reservoir member at least partially defines a reservoir chamber between the first and second end members that is capable of storing a quantity of pressurized gas for an extended duration of time. The first and second end members can be maintained in substantially-fixed axial position relative to one another. A suspension system including such a pressurized gas reservoir and a method of assembly are also included.

Abstract: The controller of the plural component proportioner (10) dispenses both components (or all three if a three component material) simultaneously (at least initially) and maintains ratio at the end of each predetermined volume of material by determining which component pump (12) has reached the desired amount of travel (given the resolution available) and using a valve (16) to shut off output of that pump until the other side has caught up. At pump changeover, the output valve for that pump (12) is shut off and the air motor (12a) allowed to run until travel stops to account for cavitation, air entrainment, compressibility, or poor inlet check performance.

Abstract: A pressurized fluid delivery system and method that can be used to interrogate objects, such as the interrogation and detonation of IEDs. The system and method entail pressurizing a liquid within a vessel with a compressed gas source so that the liquid within the vessel is at a pressure above atmospheric pressure. The pressurized liquid, the compressed gas, or a mixture thereof is then selectively delivered to an outlet, and then discharged from the outlet to physically interrogate the object.

Abstract: The invention aims at pressurising a volume (2) that needs to have a relative air pressure, in comparison with an ambient pressure, where the ambient air pressure can change rapidly and with large amplitude and where the access to pressurised air is limited. This is solved by a half open system comprising two parallel regulators (9) and (17) and two ejectors (15) and (19) working according to a split range control principle. When the relative air pressure difference is above a desired value of the second regulator (17), only the first regulator and the first ejector work. When the relative air pressure difference is below the desired value of the second regulator (17), both regulators (9) and (17) and ejectors (15) and (19) work. In this way the pressure inside the volume (2) can adapt rapidly to the changes in the ambient pressure, without leaking too much air during a static condition.
