Abstract:
A modular overfill alarm assembly is constructed and arranged to be installed in-line with a vent pipe in a vented storage tank for liquids such as waste oil or gasoline. The alarm assembly includes a vent tube having an open lower end that is threaded to be mounted to a vent opening in a vented storage tank, and an open upper end that is threaded to have a vent pipe mounted thereto, so that the vent pipe may be communicated with the vent opening as it would if it were threaded directly into the opening. The assembly further includes a support bracket mounted to the vent pipe and vent tube for supporting a commercially available alarm for actuating the alarm.
Abstract:
A system for storing waste fluids such as engine oil in bulk, which can be situated at a service station or other centralized waste storage facility. The system is charactrized by a relatively large tank having an access opening which is surrounded by a receptacle. A removable grate is provided within the receptacle over the access opening, so that articles such as oil filters may be placed in the receptacle for draining. The tank is supported relative to the ground or other flat surface by a pedestal. The system is an integral unit which may be deployed by a crane or other lifting mechanism to a desired location.
Abstract:
An improved portable fueling facility for aircraft or ground vehicles includes at least one storage tank, an outer tank for providing secondary containment about the storage tanks, a number of saddle members for supporting the outer tank on a flat horizontal surface and at least one pump for dispensing fuel. A deck compartment is provided beneath the pumps for providing secondary containment about the supply pipes which are used to supply the pumps and the refueling tubes which are used to refuel the storage tanks. The entire facility is portable, so that it may be redepolyed at different locations or airports as needed. According to one novel aspect of the facility, a control system is provided which permits self-service use of the facility in a manner which requires only the use of a commercial credit card.
Abstract:
An improved aboveground system for storing a combustible fluid such as gasoline includes a storage tank that is constructed and arranged to store a combustible fluid such as gasoline and an outer tank to provide secondary containment. An interstitial space is defined between the outer tank and the storage tank. A pipe for communicating with the storage tank extends through the wall of the storage tank, into the interstitial space and through the interstitial space for a distance so as to extend substantially parallel to at least one of the walls of the outer tank and the storage tank, and then through the wall of the outer tank, whereby fluid may be supplied to or withdrawn from the storage tank. Advantageously, access structure is provided for gaining access through the wall of the outer tank to the portion of the pipe that extends through the interstitial space for a distance so as to extend substantially parallel to at least one of the walls of the outer tank and the storage tank.
Abstract:
An improved portable fueling facility for aircraft or ground vehicles includes, in the disclosed embodiments, at least one storage tank, an outer tank for providing secondary containment about the storage tank, a number of saddle members for supporting the outer tank on a flat horizontal surface, and a pump for dispensing fuel. In one embodiment, a system is provided for suppressing combustion that might otherwise occur within the storage tank. To minimize heat transfer from outside the facility into the storage tank, fire-retardant insulation material may be positioned between the storage tank and the outer tank. The system also includes an environmentally controlled compartment for housing an electronic control system.
Abstract:
An improved fire-resistant above-ground storage tank for flammable and combustible materials is fabricated from steel plates of at least 10 gauge, the sheets being made from a ferrous alloy having a maximum of approximately 0.15% carbon and a maximum of approximately 0.8% manganese and the steel plates welded in a specific way resulting in a tank that can withstand a 2000.degree. F. environment for a minimum of two hours.

In one embodiment, a system is provided for suppressing combustion that might otherwise occur within the storage tank. To minimize heat transfer from outside the facility into the storage tank, fire-retardant insulation material is positioned between the storage tank and the outer tank. In addition, a heat sink may be positioned between the two tanks to intercept heat that would otherwise flow to the storage tank.
Abstract:
An aboveground fueling facility includes one or more vertical fuel supply tanks, each of which is positioned on a reinforced mounting pad on a fueling island that also includes one or more fuel dispensers. Fuel is supplied from the vertical fuel supply tanks to the dispensers via piping that is secondarily contained within the reinforced mounting pad. Each of the vertical fuel supply tanks may have more than one compartment so as to permit different grades of fuel to be dispensed by the dispensers, including mixtures. Fueling lanes are defined between the vertical fuel supply tanks for permitting vehicular access to the fuel dispensers. A canopy for sheltering the fueling lanes is structurally supported by the vertical fuel supply tanks, and informational signage is provided on the canopy for providing information such as fuel pricing to the consumer.
Abstract:
A modular, portable, environmentally friendly aboveground fueling assembly includes at least one pad member that is supported on the ground, and that is fabricated from a material that is heat resistant and that is resistant to exposure to petroleum products. A portable aboveground fuel tank is supported on the pad member, and at least one pumping station is included for dispensing fuel from the tank to a customer. A freestanding structure is secured to the fuel tank and the pad, and the structure is designed to give an aesthetic effect of a more substantial, permanent facility than would be given by the aboveground fuel tank standing alone. The components of the assembly are generally designed so as to be conveniently portable and so as to be simple to assemble and disassemble in the field. The assembly serves a need for inexpensive and environmentally friendly service stations, particularly in rural areas and underdeveloped countries.
