Filed:

Sep 20, 2008

Appl. No.:

12/678606

Inventors:

Ranajit Ghosh - Macungie PA, US
Jeffrey Alan Knopf - Allentown PA, US
Daniel James Gibson - Pen Argyl PA, US
Thomas Mebrahtu - Lansdale PA, US
Kevin John Giardiniere - Bethlehem PA, US

Assignee:

AIR PRODUCTS AND CHEMICALS, INC. - Allentown PA

International Classification:

B29C 35/16

US Classification:

264 28

Abstract:

A method and apparatus for discharging a temperature-controlled flow of a resultant fluid () containing a throttling gas and cryogenic fluid onto a material () for the purpose of maintaining the temperature of the material within a desired temperature range and below the glass transition temperature of the material during machining. Also disclosed is an apparatus and method for deburring or deflashing a machined material by discharging a temperature-controlled flow of a resultant fluid () onto a machined material () to harden the burrs (), then brushing the material () to remove the hardened burrs ().

Assignee:

Air Products and Chemicals Inc. - Allentown PA

International Classification:

D21C 9147

US Classification:

162 6

Appl. No.:

8/799905

Inventors:

Steven Lee Russek - Allentown PA
Jeffrey Alan Knopf - Allentown PA
Dale M. Taylor - Salt Lake City UT

Assignee:

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

B01D 5322

US Classification:

95 41

Abstract:

Oxygen is recovered from a hot, compressed oxygen-containing gas, preferably air, by an oxygen-selective ion transport membrane system. Hot, pressurized non-permeate gas from the membrane is cooled and useful work is recovered therefrom by expansion at temperatures below the operating temperature of the membrane. The recovered work is used together with the oxygen permeate product in applications such as oxygen-enriched combustion of liquid fuels, wood pulping processes, steel production from scrap in mini-mills, and metal fabrication operations. Oxygen permeate product can be compressed utilizing a gas booster compressor driven by expansion of cooled, pressurized non-permeate gas.
