Abstract: Frac valves used in completing oil and gas wells are provided. The valves comprise a cylindrical housing adapted for assembly into a liner for a well. The valve housing defines a conduit for the passage of fluids through the housing. Preferably the conduit has a substantially uniform diameter. The housing has a port which can allow fluids to pass from the conduit to the exterior of the valve. The port may be shut off or left open by a valve body mounted on the housing. Preferably, the valve body is mounted between inner and outer walls provided in the housing. An actuator is provided to move the valve body between its open and closed positions. It comprises a receiver that is adapted to receive an activation signal. Thus, the valve may be actuated by introducing a transmitter into the housing conduit which transmits an activation signal.

Abstract: Shooting supports for rifles and other long barreled firearms are provided for. The novel shooting supports comprise a sleeve and a cushion member. The sleeve has a circumference such that the sleeve is adapted to fit over a forend of a long barreled firearm. The cushion member is carried on the sleeve. It is sized such that when the sleeve is fitted on the forend the cushion member may be positioned under the forend without extending over the forend.
