  • Patent number: 6604644
    Abstract: Filler elements for a tank of combustible fluid described herein are formed from a sheet of foil mesh material by a multiple fold technique. The folding process places the free edges of the sheet in the center of the filler element where they are protected and where any piece that breaks off will be trapped. The sides are first folded inwardly and then the ends are folded inwardly. Finally, this intermediate member is rolled, formed, molded or folded further into the final desired shape for the filler element. Folding is facilitated by use of a crushed crease along desired fold lines. To reduce nesting of the mesh, various sections of the mesh corresponding to the fold lines present openings of differing sizes.

  • Patent number: 6527002
    Abstract: An apparatus (1) for use with a container (100) for storing a substance. Typically, the substance is a volatile liquid, such as hydrocarbon fuels, alcohol or distilled liquids. The apparatus (1) acts to prevent filling and evaporative losses of the liquid, minimise internal corrosion of the container (100) and prevent humidification of the liquid. The apparatus (1) employs a bladder (3a, 3b) inside the container (100). The bladder (3a, 3b) is filled with air. A pressure control unit (7) is provided to control the supply of air to the bladder (3a, 3b) such that the pressure in the bladder (3a, 3b) is maintained at or above a selected level, being the vapour pressure inside the container (100). The bladder (3a, 3b) is maintained in an inflated condition such that it fills the space above the substance in the container (100).

  • Patent number: 6283320
    Abstract: A container for volatile liquids, such a gasoline, is made of a conductive plastic material. An electrical connection is made to the container, such as by using a metal hose clamp around the neck of the container (or a threaded stud which is molded into the container), so that a conductive cable can be electrically attached to the container. At the distal end of the conductive cable a spring loaded electric clip is attached, whereby the electric clip can be connected to a conductive portion on the equipment which is to be fueled. By using the present invention, the benefits of a plastic fuel container, including arbitrary shape, absence of denting or corrosion, light weight, and inclusion of a molded handle, can all be derived without the detrimental effect of build-up of static charge which can lead to an explosion if a spark ignites volatile fuel-air vapors.

  • Publication number: 20010000837
    Abstract: A detonation safety device having a flame-arresting device positioned in a housing. A pipe extends into the housing and proximate to the flame arresting device. In order to render a detonation front traveling in a pipe harmless, the detonation front is conveyed near the flame-arresting device. The flame-arresting device includes a diameter larger than the pipe and the detonation front such that the detonation front impinges only on a partial surface of the flame-arresting device. The detonation front is expanded in front of the arresting device so as to create a deflagration, which then impinges on the outer cross-section of the flame arresting device.
