Patent number: 11703174Abstract: A clamp for repair of a pipe coupling, includes a clamp unit including a side wall with an inner surface, the inner surface having a curvature dimensioned to match an outer curvature of a pipe coupling to be repaired. A coupling on the clamp unit is constructed and arranged to couple a first portion of the clamp unit with a second portion of the clamp unit. The coupling, when secured, operates to induce a radially inward force on the inner surface of the clamp unit. A window is formed as an opening in the side wall of the clamp unit. The window is dimensioned to expose a flange of a pipe coupling to be repaired.Type: GrantFiled: June 8, 2020Date of Patent: July 18, 2023Assignee: COX ENGINEERING COMPANYInventor: Stephen J. Skinner

Patent number: 6346041Abstract: The present invention is an economizer that is capable of mixing outside air and inside air while incurring a significantly low pressure drop across the return air damper. In one embodiment, the economizer comprises a mixing chamber, a return air vent, and an outside air vent. The economizer further comprises a plurality of curved return air dampers moveable from an open position to a closed position to control the flow of return air to the mixing chamber. The economizer further comprises a plurality of straight dampers moveable from an open position to a closed position to control the flow of outside air to the mixing chamber. During operation of the economizer, a significantly lower pressure drop exists across the curved return air dampers than in conventional economizers thereby reducing the amount of energy needed to operate fans to maintain the desired air flow.Type: GrantFiled: February 4, 2000Date of Patent: February 12, 2002Assignee: Cox Engineering Company, Inc.Inventors: John S. Desmond, Rumen N. Raykov, Benjamin J. Kalinowski, Richard J. Rummo, Brett E. O'Brien, William J. Cleary, Darrell M. Kohr
