Abstract: A remotely operable closure device is disclosed. The device includes a base hub, a clamping mechanism, a closure mechanism, and a drive mechanism. The base hub is attached to a conduit and allows access to the conduit. The clamping mechanism is disposed about the base hub and is actuatable to clamp or unclamp about the base hub and a blind hub. The closure mechanism is movably connected to the clamping mechanism and is actuatable therewith to move the blind hub into or out of engagement with the base hub. The drive mechanism is remotely operable to simultaneously actuate the clamping mechanism and the closure mechanism.

Abstract: A remotely operable coupling device is disclosed. The device is suitable for coupling misaligned first and second conduits. The device includes a first connector and a second connector. The first connector is attached to the first conduit and includes a first flange with a ball end extending therefrom. The second connector is attached to the second conduit and receives the first connector. The second connector includes a first mechanism operable to position a second flange adjacent the first flange and to dispose the ball end into a socket member. The second connector also includes a second mechanism disposed about the adjacent first and second flanges and operable to hold the flanges adjacent one another and maintain the ball end disposed within the socket.

Abstract: A coupling apparatus is disclosed. The coupling apparatus includes a first connector, a second connector and a plurality of clamp devices. The first and second connectors each have a substantially hollow interior cylindrical shape with a circumferential flange with a flat surface normal to the axis of the cylinder. The flange of the second connector has a circular diameter substantially equal to a diameter of the flange of the first connector. The plurality of clamp devices has interior dimensions substantially equal to the combined thickness of first connector flange and the second connector flange when placed together along their flat surfaces and with the cylindrical portions of the first connector and the second connector substantially oriented along the same axis.
