Abstract: An abrasive blasting system that includes a blast hose; and a deadman assembly operably coupled therewith for controlling discharge out of the blast hose. The deadman assembly has a position of either a signal-flow or a no-flow position. When engaged to the signal-flow position, a burst or pulse of purge air is transferred to a mixer via a water injection conduit.

Abstract: An abrasive blasting system that includes a blast hose, and a deadman assembly coupled with the blast hose. The deadman assembly further includes a primary deadman signal device and a secondary deadman signal device. The deadman also has a base frame, with each of the primary deadman signal device and the secondary deadman signal device coupled with the base frame. There is a trigger member movably coupled with the base frame, the trigger member configured to contact and move the primary deadman signal device to a signal-flow position, and also to contact and move the secondary deadman signal device to a secondary signal-flow position.

Abstract: A wet media blasting system with a water injection system that provides more uniform distribution of the water, air and media components for achieving a more efficient mixture while minimizing the amount of water required to contain and minimize or eliminate airborne particulate matter such as dust produced during the blasting operation. The system supports dry blasting, wet blasting, and water wash down modes and air drying modes. When blasting, by more thoroughly mixing the water into the abrasive/water mix, the amount of water required is reduced. The abrasive feed is placed and shaped to optimize spray coverage and minimize abrasive flow into injection space thus mitigating water nozzle clogs. The water injectors are downstream of the air/abrasive mixing station.

There is a regulator valve disposed between the deadman assembly and the air source. The regulator is configured to reduce the pressure of airflow to the deadman assembly.

Abstract: A carrier assembly for holding a hose that includes a main body having a first portion movingly engaged with a second portion.

Abstract: A ball valve with a typical pop-up head has a central vertical threaded insert for receiving a stem. A grit suppression sleeve is placed on the stem concentric with the stem. The grit suppression sleeve is generally a spool with a center hole fitting on the stem. The inside diameter of the stem is larger than the outside diameter of the suppression sleeve, permitting the sleeve to move freely on the stem and providing a controlled air way that will not carry grit, suppressing the grit that previously was exhausted through the main ball valve exit port.

Abstract: A compression-type fitting for quick connection of two hoses or hose sections and pipe and hose section in-line is adapted primarily for industrial, heavy duty hoses typically in one to three inches in diameter, although not so limited. A commercial application for which the connector has shown to be particularly useful is in the media blasting industry where hoses are subject to extreme conditions and break or leak after a relatively short period of use, requiring frequent shut down and repair or replacement of the hoses.

Abstract: A wet dry blast system comprising having a source of pressurized air for providing a pressurized air flow, a source of pressurized water for providing a pressurized water flow, and an abrasive media source to provide an abrasive media flow. There is an abrasive release conduit for receiving the abrasive media flow, and an abrasive release orifice configured for directing the abrasive media flow along a desired or targeted portion of the abrasive release conduit.

Abstract: A wet media blasting system with a water injection system that provides more uniform distribution of the water, air and media components for achieving better application of the mixture while minimizing the amount of water required to contain and minimize or eliminate airborne particulate matter such as dust produced during the blasting operation. By more thoroughly mixing the water into the abrasive/water mix, the amount of water required is reduced. The abrasive feed is placed and shaped to optimize spray coverage and minimize abrasive flow into injection space thus mitigating water nozzle clogs. The abrasive flow is shaped as it is released from the metering valve in order to tighten the abrasive flow before it enters into the blast air stream. The shaped and tightened abrasive flow is maintained at the lower portion of the blast air stream. This positions the abrasive flow in optimum placement for spray wetting the abrasive as it flows into and through the nozzle.

Abstract: A deadman switch system includes a primary deadman switch actuator and a secondary deadman switch actuator for controlling the flow of an air/abrasive mix through a flow line of a delivery system. The secondary deadman switch is positioned in series with a primary deadman switch actuator such that the controlled flow will not function unless first the primary deadman switch and then the secondary switch are closed. The preferred embodiment of the switch is a low-profile configuration adapted to be mounted in axial alignment with the flow line in a manner to minimize interference with normal operation of the system. The switch can include multiple open/close elements, for selectively controlling different flow functions.

Abstract: A conditioning device complements a silencer with higher sound attenuation and also allows the silencer to better withstand abrasion of grit entrained exhaust air flow from decompressing an airblast pot. The device is configured to achieve four functions. First is to control and direct the exhaust air flow. Second is to absorb the impact of the entrained particles. Third is to diffuse and slow down the exhaust air velocity. Fourth is to direct and deflect the sound waves to the sound absorption surfaces located downstream.

Abstract: A fan nozzle for cleaning a surface with an abrasive blast media is constructed of a longitudinal body having an axial pathway through which the media is passed under pressure for release from a substantially rectangular cross-sectional outlet to release the media in a substantially flat, wide path. A first transition zone provides a conversion in the axial pathway from the inlet cross-section to the substantially rectangular cross-section of the outlet opening. A second transition or convergence zone first reduces and then expands the cross-section of the axial pathway for providing a Venturii acceleration of the media as it passes through the nozzle. The transition zone and the convergence zone may be coexistent along a portion of the axial pathway.
