  • Patent number: 7992593
    Abstract: An electrically conductive confined space ventilation conduit formed of a substantially rigid non-metallic conductive material, such as plastic, and a related process for ventilating an enclosure accessed by a manhole or other port. In one embodiment, the conduit has a pair of outer cylindrical sections and a central section having a cross-sectional shape of a crescent or a segment of a circle where it passes through a port to provide a minimum of obstruction for men and equipment passing through the port. Intermediate sections of varying cross-section connect the central section to the cylindrical outer sections so that the outer sections are offset from the axis of the manhole. The central section is preferably configured to obstruct no more than about 10 percent of a standard manhole opening, while causing either no air flow rate reduction, or a reduction of no more than about 10 percent as compared to the flow rate through a cylindrical conduit similar to said outer sections.

  • Patent number: 7789109
    Abstract: An expansible and collapsible tubular conduit, which is especially adapted for use in supplying pre-conditioned air to an aircraft while the aircraft is located upon the ground and is being serviced, comprises a plurality of annular fabric membranes which are connected to the opposite sides of a plurality of annular structural dividers or frame members in a continuously repetitive alternating manner. The structural combination or assembly comprising the fabric membranes and the structural dividers or frame members renders the tubular conduit readily expansible and contractible in the form of a spring or accordion so as to be capable of being easily and rapidly deployed and stowed, as well as to be capable of being stored in a relatively compact state or mode.

  • Patent number: 7730909
    Abstract: An accessory for a vapor generator, such as a smoke or fog machine, includes an elongated member that connects to an output nozzle of the vapor generator. The elongated member has one or more perforations formed in its sidewall along its length. A vapor generated by the vapor generator travels through an interior of the elongated member and escapes through the perforations to the ambient atmosphere. The effect creates a curtain of smoke or fog.
