A nozzle and process are set forth for contacting a cryogenic liquid and a gas, and discharging the resulting fluid through the nozzle. In one embodiment, the ratio of the discharged fluid's liquid component to its gaseous component is controlled as a function of the gas pressure.

Apparatus and method for regulating cryogenic spraying

A gas injector including in which a gas is passed through high-voltage/low-current electrical discharges before being discharged into the chamber of a thermal treatment furnace. The electrical activation of the gas accelerates desirable reactions between the gas, gases in the furnace chamber, and the chamber workload. Preferably, a hot electrode is electrically charged and the other parts of the gas injector and the furnace are grounded. Also provided is a method for activating an atmosphere within the reaction chamber of a controlled-atmosphere reactor.

Furnace atmosphere activation method and apparatus

An automatically actuated line connection and delivery system is disclosed for the delivery of a cryogenic fluid coolant to tools mounted on manufacturing machines such as vertical and horizontal machining centers, punching presses, thermal spray systems, welding systems, laser cutters, etc. The system includes a linearly-actuated, cryogenic fluid socket/plunger connection '()' with a differential, thermal contraction-controlled sealing mechanism, '()' as well as provisions for installing this connection on automated manufacturing machines &#x201c;()&#x201d; and integrating operation of the connection &#x201c;()&#x201d; with the manufacturing cycle controlled from a remote control panel &#x201c;()&#x201d;.

Linearly-actuated cryo-fluid connection (LACC) for manufacturing machines

A cryogenic fluid distributor for turret machine tools (e.g., lathes) directs a stream of cryogenic fluid from an external, pressurized cryogen source to a working position of a machine tool to prevent overheating of the tool. Designed for easy retrofitting and synchronizing with multi-tool turret machines, the distributor allows for a &ldquo;dual-fluid&rdquo; machining capability combining a cryogenic fluid and a conventional cutting fluid (flowing via a conventional coolant system built into a given machine tool). Made of low thermal-mass, insulating polymer and metallic parts, the distributor utilizes the different thermal contraction coefficients of the parts to establish cryogenic sealing connections, which eliminates undesired turret plate cooling and assures rapid cryogen flow start-up.

Machine tool distributor for cryogenic cooling of cutting tools on a turret plate

A staged oxy-fuel burner for producing a generally flat fuel rich flame overlying a highly radiative fuel lean flame, the burner having a fuel passage terminating in a nozzle, the fuel passage and nozzle having a generally elongated cross-section, a housing of complementary shape surrounding the fuel passage, so that when fuel is introduced into the fuel passage and an oxidizer is introduced into the passage defined by a space between the housing and the fuel passage a generally flat fuel rich flame is produced at the nozzle end of the fuel conduit and a staging nozzle for introducing oxidizer underneath and in a shape complementary to said fuel rich flame to produce a highly radiative fuel lean flame under said fuel rich flame. A precombustor having a cross-sectional shape complementary to that of flame end of the burner can be disposed on the flame end of the burner housing the precombustor having a nozzle underneath the flame end to introduce oxidizer underneath the fuel rich flame exiting the precombustor.

Low-NO.sub.x staged combustion device for controlled radiative heating

An oxy-fuel burner for producing a generally flat luminous flame, the burner having fuel passage terminating in a nozzle, the fuel passage and nozzle having a generally elongated cross-section, a housing of complementary shape surrounding the fuel passage, so that when fuel is introduced into the fuel passage and an oxidizer is introduced into the passage defined by a space between the housing and the fuel passage a generally flat luminous flame is produced at the nozzle end of the fuel conduit. A precombustor having a cross-sectional shape complementary to that of flame end of the burner can be disposed on the flame end of the burner housing to further enhance combustion and protect the burner from the furnace atmosphere.
