Abstract: Apparatus and method are provided for separating grit from liquid sewage while retaining organic solids in suspension. A sustained rotational liquid sewage first fluid flow, an induced upward liquid sewage second fluid flow, and a sustained rotational liquid sewage third fluid flow are employed in an apparatus having a cylindrical grit settling main chamber, a grit storage secondary chamber including a central grit settling access top mouth opening, a vertical shaft, a means for causing rotation of the vertical shaft, and a partition extending transversely through the main chamber and forming upper and lower subchambers. A fluid flow speed gradient is established between the liquid sewage third fluid flow and the liquid sewage first fluid flow. In this manner, grit is separated from liquid sewage.

Abstract: Apparatus for separating grit from liquid sewage while retaining organic solids in suspension. The apparatus includes a grit settling chamber, a grit storage chamber positioned below the settling chamber, and a rotating vertical shaft positioned centrally in the settling chamber. A propeller is rotatably mounted around the shaft. A conical partition extends transversely through an intermediate section of the settling chamber. Liquid sewage engages the lower part of settling chamber beneath the conical partition, and liquid separated from grit escapes from the upper part of settling-chamber above conical partition. The partition has a peripheral edge integrally mounted in fluid tight fashion to the peripheral wall of the settling chamber, and defines a central annular opening between the shaft and the partition to provide for upward flow of liquid from the lower subchamber to the upper subchamber.

Abstract: High-rise aerial apparatus mounted on a vehicle in which off-level correction is required comprises an elongate member particularly an extendable ladder or an optionally telescopic boom extending principally along one axis and able to be equipped with an aerial cage, platform or any type of similar supporting structure. The elongate member is mounted on a base, with an intermediate part interposed between the elongate member and the base, the elongate member being mounted on the intermediate part that pivots about a second axis for off-level correction of the elongate member, the intermediate part being pivotally mounted on the base via a third axis providing for elevation of a free end of the elongate member with respect to the base. Two rams for elevating and lowering the elongate member are pivotally mounted on the base and are each controlled by a controller, and can simultaneously apply off-level correction while elevating the elongate member through suitable control of the rams.
