The approved check is processed with MICR information thereby completely processing the check for use by the associated banking establishments.

Abstract: A safety valve for compressed liquid gas fuel tanks that has no man-movable parts and is completely automatic during the filling procedure. A movable piston within the valve body is responsive to pressure developing within an expansion chamber. The expansion chamber is connected to a 20% valve associated with the fuel tank and when liquid gas is detected the liquid expands and cools causing a thermal operated valve to transfer. Transferring of the thermal valve closes a port and prevents venting of the expansion chamber. Pressure building up in the expansion chamber causes the piston to automatically move, thereby shutting off the flow of fuel from the supply to the fuel tank.
