Abstract: A system for neutralizing petroleum products leaked into an enclosed portion of a fuel transfer system such as a sump. The system comprises the use of a water insoluble container having a quantity of a petroleum product mitigation agent enclosed therein. A water insoluble barrier for releasing the quantity of mitigation agent upon contact with a petroleum product permits the mitigation agent to neutralize the petroleum product as soon as it is present and in contact with the barrier. The container may be formed from polystyrene and positioned in the sump to permit the release to the petroleum products regardless of the amount of water present in the sump. In one embodiment, the tube is vertically aligned and extends from the bottom to the top of the sump. Alternatively, the container comprises a petroleum product soluble packet and includes flotation aid for maintaining the packet floating on top of any water in the sump.

Abstract: After a container is placed on a rest base beneath a beverage dispensing section where a dispensing outlet is provided, a dispensing button is depressed and a stepping motor constituting a base tilting drive device is driven for a predetermined time period to cause a linear head to be extended so that the rest base and hence a container is tilted as one unit. A dispensing valve drive device is operated to open a dispensing valve and dispense a bubbling beverage along an inner wall of the container, while suppressing any excessive formation of bubbles. When a bubble surface or liquid level of the beverage dispensed into the container rises to a predetermined level, the stepping motor is reversely driven to bring the container to an erect state. When the container becomes full with the beverage, the dispensing valve is closed, stopping the dispensing of the beverage.

Abstract: A flowable medium, such as a liquid, a semi-liquid, or a liquid containing particulate matter, can be automatically dispensed in a premeasured amount or in a continuous stream.

By using a temperature sensor in combination with a microcomputer system for the purpose of detecting large fluctuations in the temperature of the flowable medium, it is also possible to determine when the remainder of the flowable medium reaches a low level condition.
