Abstract: An all-elastomeric sealing element for a rotating control device includes a base portion, a conical portion and has a central pipe opening through both the base portion and the conical section. The conical section has an elastomeric core layer and an elastomeric surface sealing layer which encases the core layer. The surface sealing layer is softer than the core layer, as measured on a standard durometer scale.

Abstract: A safety device prevents the terminal of an electrical plug from being disengaged from or engaged with an electrical receptacle. When the terminal is engaged with the receptacle, a tubular lock-in member slides over the plug to obstruct the release of a plug securing means that secures the plug to the receptacle. A retainer member attaches to the lock-in member and engages the receptacle or a part attached to the receptacle to limit the movement of the lock-in member. When the terminal is disengaged from the receptacle, a lock-out member obstructs contact between the terminal and the receptacle and engages the plug securing means. The lock-in member obscures the plug securing means and is secured to the lock-in member by the retainer member and the keyed lockable means.

Abstract: The invention is directed to an electrical pedestal comprising an elastomeric base and housing which are configured as one piece to together define a unitary hollow enclosure for accommodating one or more electrical components.

Abstract: The invention is directed to a flexible, elastomeric slide having two major edges and two minor edges and mounting holes on the major edges for suspension underneath a solids control system. The major edges may be reinforced by rigid edge strips.

Abstract: A packing element for a blowout preventer includes an annular flexible non-metallic composite body disposed about a longitudinal axis that is adapted to be compressively displaced inwardly towards the axis. A plurality of non-metallic composite inserts are embedded in the body in generally circular fashion spaced apart in respective radial planes extending form the axis for reinforcing the body. Each of the inserts includes upper and lower flanges, and a web element extending between the flanges. The web element includes trailing and leading edges, each having outer arcuate surface that are substantially semicircular in cross-section for distributing the loads applied to a bond line between the insert and the flexible non-metallic composite body during the operation of the packing element. A central rib extends between the leading and trailing edges. The replacement of metal inserts with non-metallic composite inserts eliminates sparks and scoring of string, which leads to explosions.
