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.
