Abstract: A V-band coupling for use on an explosion-proof enclosure. The V-band coupling includes a V-band having a toughened layer along its interior surfaces for gripping the flanges on the enclosure which the V-band engages when it is installed on the enclosure. The roughened layer results in an increased coefficient of friction between the V-band and flanges which is effective for reducing the load experienced by the trunnion joints of the coupling during explosion events thereby allowing the explosion-proof enclosure to withstand high internal pressures without system failure.

Abstract: A closure assembly for sealingly closing the open top end of a material holding drum includes a cover and a rubber gasket. The cover has a central circular wall of a size corresponding to the drum open end and a peripheral flange which defines a downwardly opening annular channel for receiving the drum top end. The channel has a pair of radially spaced sidewalls, and each of the sidewalls has an annular rib for defining a seal receiving space within the channel. An annular rubber gasket is provided in the seal receiving space and has a contoured surface seated on a rounded chime on the top of the drum. The ribs engage opposite sides of the gasket to prevent lateral displacement of the gasket when the cover is fastened to the drum. An annular V-shaped groove on a top surface of the gasket defines a void between the gasket and the cover and in which a portion of the gasket is received when the gasket is deformed.

Abstract: A pressure cooker which uses an elastic C-connector to fix a cover to a cooker body in airtight manner. Loosening and tightening of the C-connector are controlled by an operating handle. The operating handle has a relief valve at one end. The relief valve has a valve body and an adjustable valve rod so that when the C-connector is in tightening condition, the valve body is located on a valve seat on the cover.
