Abstract

A gas delivery system provides a first gas which is in a liquid state under extreme pressure and in a gaseous state under intermediate pressure. A particle delivery system provides a slurry comprising the first gas in a liquid state and a second gas in a solid state. The second gas is selected so that it will solidify at a temperature at or above the temperature of the first gas in a liquid state. A nozzle assembly connected to the gas delivery system and to the particle delivery system produces a stream having a high velocity central jet comprising the slurry, a liquid sheath surrounding the central jet comprising the first gas in a liquid state and an outer jacket surrounding the liquid sheath comprising the first gas in a gas state.

Method and apparatus for cutting and abrading with sublimable particles

Patent Bingham, Dennis N [Idaho Falls, ID]

A gas delivery system provides a first gas as a liquid under extreme pressure and as a gas under intermediate pressure. Another gas delivery system provides a second gas under moderate pressure. The second gas is selected to solidify at a temperature at or above the temperature of the liquified gas. A nozzle assembly connected to the gas delivery systems produces a stream containing a liquid component, a solid component, and a gas component. The liquid component of the stream consists of a high velocity jet of the liquified first gas. The high velocity jet is surrounded by a particlemore »« less

Methods and apparatuses for cutting, abrading, and drilling

Patent Bingham, Dennis N [Idaho Falls, ID]; Swainston, Richard C [Preston, ID]; Palmer, Gary L [Shelley, ID]; ...

Methods and apparatuses for treating a surface of a work piece are described. In one implementation, a laser delivery subsystem is configured to direct a laser beam toward a treatment zone on a work surface. A cryogenic material delivery subsystem is operably coupled with the laser delivery subsystem and is configured to direct a stream comprising cryogenic material toward the treatment zone. Both the laser beam and stream cooperate to treat material of the work surface within the treatment zone. In one aspect, a nozzle assembly provides the laser beam and stream of cryogenic material along a common flow axis.more »« less
