Abstract: A method for installing a pipe closing apparatus in an oil well rig system positioned at least partially in a body of water, comprising the steps of shutting off a flow of oil through a well head, removing a section of riser pipe from the oil well rig system and connecting the pipe closing apparatus to a remaining portion of riser pipe and positioning the pipe closing apparatus between the remaining portion of riser pipe and the well head.

Abstract: The torque resisting system for a helicopter which includes a body. Main rotor and a tail rotor, the system includes a deflector connected to an actuator for moving the deflector relative to the body. The system further includes a sensor that is operationally associated with the tail rotor and the actuator, such that the actuator moves the deflector upon: receiving a signal indicating that the tail rotor is operating below a predetermined rotation or a determination that the sensor is inoperable or absent.

Abstract: An apparatus which includes a housing defining a chamber, the chamber being sealed from an exterior of the housing, wherein the housing further defines an opening in fluid communication with the chamber and the exterior of the housing. The apparatus further includes a valve in fluid communication with the opening and positioned between the chamber and the exterior of the housing and a member at least partially positioned within the chamber and moveable relative to the housing such that opening of the valve allows fluid to enter the chamber from the exterior of the housing and move the member. A method to operate the same is provided.

Abstract: A torque resisting device for a helicopter, wherein the helicopter includes a body and a main rotor. The device includes a deflector secured to and movable relative to the body, wherein the body includes opposing lateral sides and the deflector is movable to a position to extend away from only one of the lateral sides of the opposing lateral sides. The deflector includes a dimension extending in a plane generally non-parallel to a plane of the main rotor. Further included is a method for counteracting a torque created by the rotation of a main rotor of a helicopter.

Abstract: An improved regenerative gas drying system (30) having an adsorbing chamber (36) and a regenerating chamber (46) with both chambers containing desiccant (38) in which the adsorbing chamber (36) receives wet gas (31) for adsorption of moisture by the desiccant (38) contained therein to create a drier gas (40) and in which a portion of the drier gas (40) exits the adsorbing chamber (36) and is directed and carried to the regenerating chamber (46) to dry the desiccant (38) contained within the regenerating chamber (46).

Abstract: A gas drying device (30) in which wet gas (31) is introduced into a chamber (36) containing desiccant (38) in which the desiccant (38) adsorbs moisture from the wet gas (31) to dry the wet gas (31) and in which energy is utilized to energize and to remove the moisture from the desiccant (38) to dry and to regenerate the desiccant (38) for reuse to dry wet gas (31) includes a microwave generator (52) and an antenna member (48) in communication with microwaves (50) generated by the microwave generator (52) in which at least a portion of the antenna (48) is disposed within the chamber (46).
