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.
Claims21
An abrasive blasting system comprising:
- a blast hose;
- a mixer coupled with the blast hose;
- a deadman assembly operably configured in a deadman position of one of:
- a signal-flow position and a signal-no flow position;
- an air source coupled with the mixer via an air injection conduit in order to provide an air flow to the mixer in response to the deadman position;
- a water source coupled with the mixer via a water injection conduit;
- and
- an abrasive source coupled with the mixer via a media conduit in order to provide a media flow in the mixer in response to the deadman position,
- wherein upon engagement of the deadman assembly to the signal-flow position, at least part of the air flow is diverted into the mixer via the water injection conduit.

8-22. (canceled)
An abrasive blasting system comprising:
- a blast hose;
- a mixer coupled with the blast hose;
- a water pump operable to provide a pressurized water flow;
- a snubber in fluid communication with the water pump;
- a main water regulator downstream of the snubber;
- a second water regulator downstream and in fluid communication with the main water regulator;
- a deadman assembly operably configured to be in a deadman position of one of:
- a signal-flow position and a signal-no flow position;
- an air source coupled with the mixer via an air injection conduit in order to provide an air flow to the mixer in response to the deadman position;
- a water source coupled with the water pump in order to provide a water flow to the water pump in response to the deadman position;
- an abrasive source coupled with the mixer via a media conduit in order to provide a media flow in the mixer in response to the deadman position;
- a first water injector in fluid communication with each of the air source and the water source;
- wherein upon engagement of the deadman assembly to the signal-flow position, at least part of the air flow is diverted into the mixer via the first water injector.

An abrasive blasting system comprising:
- a blast hose;
- a mixer coupled with the blast hose;
- a water pump operable to provide a pressurized water flow;
- a snubber in fluid communication with the water pump in order to receive the pressurized water flow, the snubber providing a snubber outlet flow;
- a main water regulator configured to receive the snubber outlet flow and reduce its pressure to form a first reduced pressure flow;
- a second water regulator configured to receive the first reduced pressure flow and reduce its pressure to form a second reduced pressure flow;
- a deadman assembly operably configured to be in a deadman position of one of:
- a signal-flow position and a signal-no flow position;
- an air source coupled with the mixer via an air injection conduit in order to provide an air flow to the mixer in response to the deadman position;
- a water source coupled with the water pump in order to provide a water flow to the water pump in response to the deadman position;
- an abrasive source coupled with the mixer via a media conduit in order to provide a media flow in the mixer in response to the deadman position;
- and
- a first water injector coupled with each of the air source and the water source;
- wherein upon engagement of the deadman assembly to the signal-flow position, at least part of the air flow is diverted into the mixer via the first water injector.
