Patent number: 8323080Abstract: System and method for controlled atmosphere stunning of chickens or turkeys in a batch mode is provided. The disclosed method includes the steps of: loading one or more batches of chickens or turkeys in a stunning chamber and sealably enclosing the stunning chamber to isolate the atmosphere therein. Carbon dioxide is then introduced to the isolated atmosphere in a series of three, four, five or more phases to humanely stun and eventually kill the poultry. The carbon dioxide containing atmosphere is subsequently forcibly exhausted from the stunning chamber and the ranks of cages or modules containing the stunned poultry are advanced to a subsequent processing station such as a tipper or dumping station.Type: GrantFiled: April 11, 2008Date of Patent: December 4, 2012Assignee: Praxair Technology, Inc.Inventors: Gary Dee Lang, Narsimha R.

Patent number: 6335074Abstract: A thermal insulation panel exhibits little or no warping due to temperature differences between different portions of the panel. The panel comprises insulation material and an envelope for encapsulating the insulation material. The envelope comprises a base member and a cover member. The cover member is supported by the base member in a floating and sealing engagement with the base member. The cover member can slide relative to the base member to compensate for differential thermal expansion effects on the respective base member and cover member. In an alternative embodiment the cover member is adapted to be exposed to a temperature significantly below the temperature to which the base member is exposed. The cover member is formed of a metal having a low coefficient of thermal expansion to compensate for differential thermal expansion effects in the respective base member and cover member. The cover member and the base member are joined to provide the envelope with a hermetic seal.Type: GrantFiled: February 29, 2000Date of Patent: January 1, 2002Assignee: Praxair Technology, Inc.Inventors: Theodore Hall Gasteyer, III, Gary Dee Lang

Patent number: 6334330Abstract: A cooling tunnel system that includes a conveyor for carrying objects through a tunnel chamber. The conveyor enables a cooling fluid to pass therethrouqh and about the objects. A plurality of slot means feeds the cooling fluid to the conveyor means. Each slot means includes at least one aperture for enabling vapor flow onto and about the objects. A plenum adjacent the plurality of slot means distributes the cooling fluid. And at least one fan in the tunnel chamber causes a flow of the cooling fluid into the plenum and through the slot means with sufficient velocity to impinge upon and cool the objects and to recirculate the cooling fluid within the tunnel chamber.Type: GrantFiled: January 22, 2001Date of Patent: January 1, 2002Assignee: Praxair, Inc.Inventors: Gary Dee Lang, Theodore Hall Gasteyer, III, Yeu-Chaun Simon Ho
