Abstract: A recoil device is provided for a gun having a barrel with a breech. The device includes a breech nut, a brake assembly, a pneumatic spring and a counter-recoil buffer. The breech nut has first and second adjacent sides. The brake assembly includes a brake cylinder that mounts to the breech nut on the first side. The pneumatic spring mounts to the breech nut on the second side. The counter-recoil buffer attaches to the pneumatic spring. The brake cylinder and the pneumatic spring internally push fluids for recoil absorption and return in response to firing the gun.

Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A method and apparatus for separating entrained gases from a pumped fluid. A degas pipe having an increased inner dimension relative to surrounding process piping is provided to generate a stratified two-phase gas/liquid flow. A controlled release mechanism permits selective removal of gas from the degas pipe.

Abstract: A high pressure breathing gas transfer system is provided where high pressure air from a tank of one SCBA, or a central storage supply, can be quickly transferred directly into the high pressure air tank of a second SCBA. The transfer process, between two SCBA's, is accomplished by attaching a high pressure conduit line between two quick connect check valves situated on the high pressure sides of the SCBA's. The high pressure transfer line has a quick connect coupling attached to each end to enable connection to the check valves. After the line is attached, a lever is depressed on donor couplings to open the donor check valve. High pressure air then flows out of the donor tank and forces the check valve open on the donee tank. The air transfer continues until the internal pressure of the two tanks is equalized and the donee tank has received half of the air that was initially inside the donor tank.
