Abstract: A self-contained respiratory protection system is disclosed. The system includes a center module attachable to one or more cylinders of air, gas or oxygen. A plurality of filters is mountable on the center module. A blower motor also may be mounted on the center module. A hose attaches to a cylinder to provide air to an operator or draws filtered air via the filters on the center module. A first stage regulator converts the air in the cylinder to breathable air for the operator. A second stage regulator transitions between filter mode and supplied air. The system may fit within a backpack.

Abstract: Apparatus for controlling the torque delivered to pipe connections by power tongs by utilizing the reaction torque to cause a proportional fluid by-pass to be bled from the drive motor fluid power supply to slow the motor as torque increases, and to stop the motor at some preselected torque quantity. The torque is maintained as long as the operator provides fluid power to the motor circuit to overcome brief torque resistances due to such as pipe wobble.
