Abstract: An emergency valve is provided to shut off the flow of fuel in the event a fuel dispenser is struck with sufficient force to rupture the fuel conduit means therefor. The valve comprises a lower housing connected to a source of pressurized fuel and an upper housing connected to conduit means which extend to a dispensing nozzle. The upper housing has a groove which defines the plane of a weakened portion. When the impacted with a relatively high lateral force, the portion of the upper housing, above the groove, will separate, or break away. A normally open, main control, flapper valve is mounted in the lower housing. A poppet check valve is mounted in the upper housing. When the separable portion of the upper housing breaks away, both the flapper valve and the check valve automatically close to minimize spillage of fuel. A bleed valve is provided to relieve pressure in the fuel conduit means to which the separable portion of the upper housing is connected, in the event a fire occurs upon its breaking away.

Abstract: A liquid spill container and method of making and installing the same are provided wherein such container has a side wall comprised of at least two separate portions which are detachably fastened together. One of the portions defines the sole structure of the container which is adapted to be embedded in a fixed manner in an associated substrate to provide the sole support for the container in such substrate and the other of the portions being detachable from the one portion with the one portion embedded in the substrate to enable replacement of such other portion.

Abstract: An automatic shut-off nozzle has liquid flow through its vapor return automatically stopped when liquid has filled the vapor line sufficiently in a predetermined period of time to move a float valve to block the vapor return line. This blocking of the vapor return line by the liquid increases the pressure in the tank being filled to cause the automatic shut-off nozzle to stop liquid flow. If the pressure in the tank increases beyond a predetermined pressure when the float valve is in its blocking position, the increased pressure is vented. The automatic shut-off nozzle also stops flow in response to the tank being filled to a predetermined level with liquid or to the pressure in the tank exceeding a predetermined pressure even when there is no blocking of the vapor line by the float valve.
