Appl. No.:

10/260191

Inventors:

David Allen Greene - Uniondale NY, US
Anthony Mark Fabella - Centereach NY, US
Herbert Rosenthal - Boynton Beach FL, US

Assignee:

Woody's Lumber, Inc. - Farmingdale NY

International Classification:

B21D 47/00

US Classification:

29897312, 2989731, 29458

Abstract:

A clamping fixture for use in the assembly of a gate comprised of a number of plastic members includes a flat stationary clamping surface attached to a stationary frame and a flat moving clamping surface extending parallel to the flat clamping surface and driven toward the flat clamping surface by an actuator, so that the plastic members, assembled in the configuration of the gate, are clamped and held between the clamping surfaces. Preferably, the actuator, which includes one or more pneumatic cylinders, is adjustable along the frame to provide for the assembly of gates having different widths. Preferably, the clamping fixture additionally includes a stationary flat guiding strip extending perpendicularly from an end of the flat stationary clamping surface toward the flat moving clamping surface.

US Classification:

423244

Abstract:

Flue gas is desulfurized by absorbing it onto a selective absorbent-catalytic material. The absorbed SO. sub. 2 is recovered by contacting it in a desorption cycle with a reducing desorption gas. In one embodiment, multiple absorbent beds are employed and alternate absorption-desorption cycles are used in each of the multiple beds with the flue gas and the desorption gas used alternately. The sulfur oxide is recovered in concentrated form in the desorption gas stream and is then utilized as feed in a conventional sulfuric acid plant yielding concentrated sulfuric acid.
