  • Patent number: 6543968
    Abstract: A submersible canal bypass is used to successively bypass the flow around distinct sections of an earthen canal for lining. The canal bypass is placed within the canal and uses a plurality of pipelines and a plurality of bulkheads assembled from portable modular sections. The headgates on the portable modular sections are so arranged along the bulkhead to divert the flow of water through bypass pipelines so as to isolate a section of the canal during lining activities and return the flow of water to the lined canal after lining.

  • Patent number: 6533352
    Abstract: A chair having a seat and a back rest. The back rest is attached to the seat via a back rest support element. The flat spring can be made from a non-metallic material, such as from fiberglass. The back rest support element comprises a flat spring disposed under pretension. In one embodiment, the seat is disposed upon a seat support structure having four legs. Preferably, the legs are splayed outside the perimeter of the seat, so that the chair is stackable with chairs of like design. The seat and the back rest can be made from a lightweight plastic material, and that the support structure can be made from tubular steel.

  • Patent number: 6495931
    Abstract: A controller housing for a water pool apparatus has two separate enclosures disposed back-to-back. The two separate enclosures are electrically connectable by electrical connectors disposed in the adjoining walls of the two enclosures. The electrical connections are aligned with one another so that pressing the two enclosures towards one another automatically places the two enclosures into electrical communication. In one embodiment of the invention, the two enclosures are attached to one another by a pair of disengageable hinges.

  • Patent number: 6484350
    Abstract: A bagless canister vacuum cleaner having a chasse, an air blower and a dust extraction and collection unit is provided. The dust extraction and collection unit has an easily removable inlet chamber and an easily removable outlet chamber. The inlet chamber is substantially cylindrical, and the outlet chamber is disposed concentrically within the upper portion of the inlet chamber. Duct work within the chasse conducts air from the air inlet and into the inlet chamber in tangential fashion, such that air swirls about the inside walls of the inlet chamber. Air within the inlet chamber is then allowed to escape from the inlet chamber into the outlet chamber via a plurality of small holes disposed in the side walls of the outlet chamber. Air within the outlet chamber is exhausted to the blower via a top wall opening in the outlet chamber.

  • Patent number: 6485230
    Abstract: A modular dike is used to divide a body of water into two distinct parts. The modular dike uses a plurality of floatable modules. Each module is floated into the body of water and sunk at predetermined locations in the body of water. The modules are aligned in a row within the body of water so that the row of modules forms a dike which effectively segregates the body of water into two distinct parts.

  • Patent number: 6467207
    Abstract: A display apparatus has a roll of film with multiple still images disposed along the roll of film. The roll of film is scrollable by one or more electric motors to display one or more of the still images on the roll of film at a visual display location. The display apparatus is capable of oscillating desired images on display at the visual display location so as to attract the eye of the observer.

  • Patent number: 6462249
    Abstract: A process for the low temperature, non-incineration decontamination of contaminated materials, such as chemical weapon components containing residual quantities of chemical warfare agents. The process includes the steps of (a) contacting the contaminated materials with steam at substantially ambient pressure in a substantially dry first heated vessel for a period of at least about 15 minutes, the steam being at a temperature of at least about 560° C., (b) removing condensible and non-condensible gases from the first heated vessel and heating them in a second vessel at substantially ambient pressures to temperatures of at least about 500° C. for a period of at least about one second in an atmosphere containing steam in a concentration greater than about 250% of stoichiometry, and (c) catalytically treating non-condensible gases from the second vessel in the presence of oxygen so as to reduce the concentration of chemical warfare agents to less than about 1.0 mg/m3 at standard temperature and pressure.

  • Patent number: 6454523
    Abstract: A water pool apparatus, such as a portable spa, pool, hot tub or recirculating bath tub having a double seal configuration. The water pool apparatus has a water recirculation system which includes a centrifugal pump. The centrifugal pump has a double seal which includes a seal housing and a pair of spaced-apart seals. The seal housing defines an enclosed reservoir chamber. By the invention, any liquids which are successful in leaking past the first seal are trapped within the reservoir chamber. As the reservoir chamber accumulates liquid, the liquid can be recycled back into the water recirculation system by a drain conduit running between the reservoir chamber and the suction side of the pump.

  • Patent number: 6444337
    Abstract: A method of generating electricity from a fuel cell comprises the steps of (i) providing a fuel, such as molecular hydrogen, to an anode electrocatalyst, (ii) providing an oxygen-containing liquid to a cathode electrocatalyst, (iii) converting the fuel to positive ions via the anode electrocatalyst and the anode, while simultaneously converting the oxygen-containing liquid to yield hydroxyl or oxygen ions via the cathode electrocatalyst and the cathode, and (iv) continuously or periodically reoxidizing the oxygen-containing liquid by contacting the oxygen-containing liquid with molecular oxygen. In the method, at least about 90% of the oxygen provided to the cathode is provided by the oxygen-containing liquid.

  • Patent number: 6434889
    Abstract: An antenna support structure has the outward appearance of a palm tree. The antenna support structure has a vertical support pole with an upper portion, an intermediate portion and a lower portion. The lower portion is of a color and texture to resemble the trunk of a palm tree. Disposed outwardly from the intermediate portion is a plurality of antenna receptor members appropriately configured to receive desired electromagnetic signal waves. At the top of the support pole is a plurality of green members having the appearance of new palm fronds. Below the green members are a plurality of drooping members disposed downwardly about the intermediate portion of the support pole and covering the antenna receptor members. The drooping members have colors and textures to resemble a palm tree skirt.
