An electro-pneumatic controller for use with a regulator. The electro-pneumatic controller includes a base having a body, a top surface, and a bore formed within the body. A locking mechanism is disposed within the bore of the body of the base, the locking mechanism having a top surface flush with the top surface of the base. A cover is coupled to the base and includes an open end with a rim, the rim contacting the top surface of the base and a portion of the top surface of the locking mechanism. The locking mechanism is rotated via a tool in a counter-clockwise direction after the cover contacts a portion of the top surface of the locking mechanism to lock the cover to the base.

A secure valve access system includes a cover mounted over the valve stem of a valve. The cover is attached to a support which is mounted on the valve so the cover cannot be removed. Fasteners extend through the support and are selectively jammed against a wrench flat thereby providing a torque transmitting connection between the cover and a valve operator. Retraction of the fasteners breaks the torque transmitting connection allowing the cover to free wheel thereby preventing unauthorized operation of the valve. Rotation of the fasteners is done by an unusual drive socket.

A manually-operated diaphragm valve in which the open/close range of a valve disk can be set while compactness is maintained with a simple structure, and a sufficient flow rate at the time of full open is ensured. A valve main body (1) includes a valve disk (12) attached inside a body (10) and a spindle (13) screw-fastened to the body so as to be able to ascend and descend to cause the valve disk to make contact with and go away from a valve seat (14). A handle for manually performing rotating operation of the spindle is mounted above the valve main body. A full-open position adjustment mechanism (20) which limits rotation of the handle on a valve-opening operation side at full open and sets an upper limit of a flow rate when the valve disk is fully open is provided near an upper portion of the valve main body.

A pipe stopper includes an expandable stopper body defining a stopper cavity and configurable in an expanded configuration and a contracted configuration; a pressure assembly comprising a pressure housing and a piston, the piston slidably engaged with a housing cavity of the pressure housing, the piston operatively connected to the expandable stopper body; and a locking assembly comprising a locking ring movable between a locked configuration and an unlocked configuration, wherein the locking ring is configured to engage the expandable stopper body in the locked configuration to prohibit contraction of the expandable stopper body and to secure the pipe stopper in the expanded configuration.

Apparatus and methods for providing extracorporeal blood circulation and oxygenation control include multi-stage deairing of blood to provide automated cardiopulmonary replacement to sustain patient life during a medical procedure such as; cardiopulmonary bypass graft surgery, keyhole cardiopulmonary bypass graft surgery, percutaneous angioplasty, percutaneous stent placement, and percutaneous atherectomy, repairing or replacing the heart valve and/or for perfusing an organ or the body of an organ donor to preserve viability of organ(s) for transplantation.

In one embodiment, a tangible, non-transitory computer-readable medium includes computer instructions stored thereon. The computer instructions, when executed by a processor, may cause the processor to receive historical data associated with placing a machine in an industrial environment offline, to determine one or more recommendations for the machine, one or more parts of the machine, or both based on the historical data, to determine an authority level of one or more users requesting to place the machine offline, and to display the one or more recommendations based on the authority level of the one or more users.
