Abstract: A roof mounted ventilation assembly having an integrated supply and relief fan assembly. The assembly is drum shaped with a central portion circumferentially defined by centrifugal blades that extend between top and bottom plates. Both top and bottom plates have a central opening, respectively, and axial supply fan blades are disposed within the central opening of the top plate. A supply duct extends through the central portion, fluidly coupling the central openings. The supply duct fluidly communicates a roof-mounted air intake to a supply discharge plenum operatively associated with an interior space. An inlet collar is fluidly couples the remainder of the central portion not closed off by the supply duct to the interior space, wherein relief air in this remainder of the central portion is urged by the centrifugal blades out exhaust ducts to the external environment in a direction transverse relative to axial supply air.

Abstract: A roof mounted ventilation assembly having fluidly coupled supply and relief fans is provided. One drive unit assembly may be operatively associated with both fans. A rotatably and vertically movable duct fluidly couples a supply discharge plenum to a roof-mounted air intake hood so that the former may move vertically and rotatably relative to the latter, thereby the present invention can selectively pressurize the spaced inhabited by the supply discharge plenum through a positive supply to relief air volume ratio.

Abstract: A method for forecasting future telecommunications network growth so as to maximize carrier profitability. The method being a service-driven network planning method for more accurately forecasting the future equipment needs of telecommunications carriers. A plurality of different service forecasts are utilized to create a network model. These forecasts are translated into bandwidth flows and modeled as they traverse the network. An amalgamation of these flows is translated into equipment needs and existing equipment is subtracted from the needs to result in a long-term equipment needs forecast. Financial metrics that model the carrier business plan are also employed to generate a forecasted profit and loss statement. With such a statement, long-term strategic issues that will impact carrier performance and profitability can be identified.

Abstract: A lane distribution apparatus for distribution of articles in a single lane to multiple lanes. A rocker plate and associated rocker arms are used to shift simultaneously lanes both upstream and downstream of a distribution point. The apparatus and process permits lane changes in a short period of time, which minimizes the risk of product stoppage and maximizes the speed with which products can be conveyed.

Abstract: A battery operated storage container which is divided into two compartments, one for bait and a second for fish caught. It incorporates a pump for filling the compartments to a preset level and a pump to empty the compartments. It also contains an electronic control panel which allows the user to select which functions he/she wants to perform. These functions include filling, emptying, recycling, and aerating the water. The functions can be performed simultaneously or independently.
