Abstract: A sign assembly supported above a supporting surface includes at least one sign frame, an upstanding hinge rod assembly mounted on the supporting surface, and a hinge plate rotatably supported by the hinge rod assembly is connected to one frame side. The other frame side connects to a second plate that is supported by a pre-installed post or another hinge rod assembly. The angles of the one or more sign frames can be changed to meet installation requirements until the post mounts and/or hinge rod assemblies are fixed relative the supporting surface.

Abstract: A displaying bumper guard for fuel dispensers that includes a sign-holding frame assembly mounted on an inverted U-shaped bumper guard member with the bumper guard legs imbedded in the ground level concrete or concrete ledge. The device includes a frame for supporting a sign and a mounting assembly for securing the frame to the bumper guard member. The visual square footage of the frame, viewed normally thereto, is much larger than that of the bumper guard member thus providing a good visual barrier for the dispensers. In one exemplary embodiment, the bracket assembly is releasably secured to the center leg of the guard member and includes at least one and preferably two displaced mounting surface located a short distance from the side profile of the bumper guard member. The frame includes at least one and preferably two spaced elongated reinforcement frame rails or bars secured to the frame sides to strengthen the frame and to cooperate with the mounting surface by being releasably secured thereto.

Abstract: A fuel tanker truck for and a method of transporting liquid fuel, in a tanker truck having a fuel storage compartment and a delivery pipe having a compartment end controllably communicating with the interior of the tanker storage compartment and a distal end having an adaptor. The method includes substantially filling the delivery pipe with liquid fuel, transporting the fuel in the delivery pipe, and during or after the transporting step, trapping and sealing the liquid fuel within the delivery pipe in response to the storage compartment end of the delivery pipe separating from controllable communication with the interior of the storage compartment.

Abstract: A vent valve assembly with roll over shut-off capability includes a housing, a vent valve that opens to allow vapor to escape from the tank in response to tank vapor pressure greater than a predetermined positive pressure and that opens to allow air or vapor entrance to the tank in response to tank vapor pressure below a predetermined negative pressure. A roll over valve is provided to open and close the fluid flow path between the vent valve and the tank interior, and a rocker arm assembly is rotatably mounted to the housing for positioning the roll over valve in the open position when the tanker is upright and for moving the roll over valve to the closed position when the tanker rolls more than a predetermined angle relative to the upright position. Stored liquid rising above the shut-off valve applies a further force closing the shut-off valve in relation to the head pressure.
