  • Patent number: 6250348
    Abstract: An improved refueling system is provided for faster and safer pit stop refueling of a race car during a race. The refueling system is particularly designed for faster gravity drain flow of fuel from a pitside fuel tank to a fuel cell on the race car. The refueling system comprises an improved fuel nozzle adapted for quick and easy engagement with a mating receiver on the race car. In the course of engaging the fuel nozzle with the receiver, a poppet-type valve in the nozzle is moved to a full-open position defining a substantially unobstructed flow path for fuel flow through the nozzle at a substantially optimized flow rate to achieve refueling of the race car in the shortest possible time. The fuel nozzle is quickly and easily disengaged from the car receiver, and such disengagement is accompanied by automatic closure of the poppet-type valve.

  • Patent number: 6192948
    Abstract: A closure for a transportable container used in the transfer of materials to or from an enclosed process area is described. The container docks with a port in a wall of the process area forming a sealed connecting chamber which is sterilized by irradiation. Communication between the interiors of the container and the process area is then established. The closure has a collar and a lid, which portions are formed so that all the surfaces which form part of the connecting chamber in use are in the direct line of the sterilizing radiation, which is normally ultra-violet or pulsed white light radiation. No relevant surface is shadowed from the radiation. The lid may be formed integrally with the collar with a thin web separating the two to define a fracture line. The lid is provided with a grip which can be grasped from within the process area. Application of a pulling force to the grip causes the lid to be pealed away from the collar without the generation of particulates.

  • Patent number: 6076569
    Abstract: A cup rinse with a valvular ring according to the invention is disclosed. The valvular ring has a plurality of valves in the center thereof. When an inlet tube is inserted through the valvular ring, the valves are forced to open thereby to allow a chemical liquid to flow into the cup resin via the inlet tube. Inversely when the inlet tube is completely pulled out of the valvular ring, the valves are tightly closed without a chemical liquid leakage. Accordingly, the cup rinse of the invention can prevent peripheral precision instruments, such as a motor, from damage by a leaky chemical liquid. Thus, the cup rinse of the invention cannot cause any unnecessary cost consumption.

  • Patent number: 4678014
    Abstract: A hand-holdable inflating/deflating device is disclosed which can be used for conveniently effecting inflation or deflation of an associated article. The inflator includes an electric motor which drives a centrifugal impeller, with the motor and impeller carried by a mounting frame. The device further includes a generally cylindrical housing within which the motor and impeller are positioned, whereby operation of the motor rotates the impeller to create axial airflow within the housing. Significantly, the housing of the device comprises a one-piece injection molding, with the housing specifically configured to promote highly efficient assembly with the other components of the device. Further, a detachable, reversibly positionable nozzle is provided which can be fitted to either end of the molded housing, thus facilitating use of the device for either inflation or deflation.

  • Patent number: 4598741
    Abstract: A barrier vapor control system includes a seal inside an automobile filler pipe for engaging the fuel delivery conduit of a pump nozzle to prevent the escape of hydrocarbon vapors out of the filler pipe into the atmosphere while the fuel tank is being refilled. A vapor recovery conduit downstream of the seal carries the vapors displaced by filling the fuel tank to a cannister that contains a scrubbing agent. A vacuum accumulator and a vacuum pump draw fresh air and the vapors from the fuel tank through the cannister to remove hydrocarbon vapors from the effluent vapors of the fuel tank.
