Abstract: A check valve for use in a flow line has a valve body which includes a first portion with an inlet and an outlet, the inlet and outlet being substantially aligned with one another. The valve body further includes a second portion with tubular member having an longitudinal passage for receiving fluid from the inlet passage with outlet ports extending radially from the longitudinal passage and with a flange member extending annularly around tubular member. A plunger is mounted with the valve body for preventing fluid flow through the outlet ports and includes a plug mounted with the tubular member in its longitudinal passage to deflect the flow of fluid through the outlet ports and a tubular sleeve circumscribes the tubular member. The spring is mounted with the valve body for urging the plunger toward the inlet passage. The flow of fluid through the valve is checked when the pressure in the inlet passage is insufficient to overcome the urging of the spring.

Abstract: Apparatus for transporting material separated from a flowing fluid from one location to another is disclosed. The apparatus mounts a cyclone separator on one end of an elongated container with the separator including a body having an inlet passage, a fluid outlet passage and a separated material outlet passage. The container is pivoted about an axis disposed reversely to the elongated axis of the container up to a point where the cyclone separator is operational. The flowing fluid and material passes through the inlet passageway where the material is separated from the fluid and dropped into the container, the fluid continuing through the fluid outlet passageway and back into the system from which it was withdrawn. The container is then moved about the transverse axis from the separating position back to the transporting position, the container and separated material held therein being transported to the other location.

Abstract: A pneumatic relay valve is actuated by a pressure differential determined by the respective surface areas of two opposing surfaces of a piston moveable within the valve body. A first pressure (pilot signal) to be monitored maintains the piston member of the valve in its "in-service" position, blocking all ports in the valve body. Upon the occurrence of a sufficient pilot signal pressure drop, a second continuous common supply pressure moves the piston to a "tripped" position, sealing off the pilot signal inlet port to enable the second (common supply) pressure to bleed to the atmosphere. This sudden loss of common supply pressure causes a common supply relay valve to "trip," closing off all common supply fluid pressures to each of a plurality of first relay valves. Only upon reinstatement of the first interrupted pilot signal pressure may the relay valve be manually reset to the "in-service" position and maintained in that position by sufficient pilot signal pressure.

Abstract: A method of and apparatus for preventing fluid leaks out of a well which involves installing a blowout preventer at a wellhead, the preventer has a body with a bore communicating with a bore hole and a clamping means for controlling the passage of fluid through the bore. Means are provided for directing sealant into the bore beneath the clamping means so that when an occurrence of a blowout is sensed, the clamping means are closed to inhibit flow of fluid up the bore and a sealant is injected through the directing means into the bore so that the sealant is carried to the closed clamping means which forms a seal to insure that fluid does not leak past the closed clamping means.
