Abstract: An end-port regenerative furnace (10) includes a housing; a combustion chamber (14) within the housing; first and second regenerators (24, 26) each disposed to be in communication with the combustion chamber; and first and second lance assemblies (20, 22) adapted to inject pure fuel gas and pure oxygen concurrent into the half of the combustion chamber closest to a discharge end with a respective one of the first and second regenerators. The first and second regenerators are each constructed and arranged to alternate between a combustion mode and an exhaust mode for the combustion products circulating in the combustion chamber.

Abstract: An adjustable mounting assembly has first and second mounting portions. The first mounting portion has an engagement arm with an adjustable end having first engagement teeth disposed about a first axis of rotation. The end portion has an adjustable second portion rotatable about the first axis of rotation, and having second engagement teeth that intermesh with the first engagement teeth to retain the second portion in an adjustable pan-position. The second portion has third engagement teeth disposed about a second axis of rotation angularly offset from the first axis of rotation. A second mounting portion is adjustably attached at an attachment portion to the first mounting portion, and the attachment portion has fourth engagement teeth disposed about the second axis of rotation that intermesh with the third engagement teeth to retain the second mounting portion is a selected tilt position.
