Abstract: A nozzle assembly comprises a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; and a switching valve assembly disposed in the central bore that directs fluid flow to ports upon application of fluid flow above a predetermined threshold to the inlet and directs fluid flow to different ports upon fluid flow having subsequently dropped below the predetermined threshold and then exceeding the predetermined threshold. The assembly comprises a cylindrical poppet slidably disposed within the central bore, a guide between the nozzle body and the poppet, and a biasing member within the cartridge case between the front portion of the nozzle body and the poppet urging the poppet away from the front portion of the cartridge case.

Abstract: A frame apparatus for holding a flexible lance positioning drive device adjacent to and spaced from a heat exchanger tube sheet includes an upper guide rail carrying a movable carriage supporting a drive positioner rail having a drive support carriage and an air motor drive assembly fastened to each of the carriages, each air motor drive assembly comprising an air motor having a shaft driving a spur gear through a worm gear reducer, wherein the spur gear is carried within a spur gear housing fastened to the worm gear reducer, and the air motor assembly is fastened to the carriage via the spur gear housing. The spur gear housing is selectively rotatable on the carriage between a locked position with the spur gear engaging the rail to which the carriage is mounted and an unlocked position with the spur gear disengaged with the rail to which the carriage is mounted.

Abstract: A speed retarding device for a rotary nozzle includes a hollow cylindrical housing and a rotatable tubular shaft rotatably carried by the housing. The shaft has a central axial bore and an enlarged drag sleeve portion carried in the housing. A pair of support bearings support the drag sleeve portion of the shaft in the housing. An annular inner seal between each of the support bearings and the drag sleeve portion defines a cavity within the housing receiving a viscous fluid confined within the cavity. The drag sleeve portion includes a peripheral helical groove and a plurality of axial bores extending therethrough parallel to the central bore, one or more blind axial bores each having a closed end an open end, and a piston disposed in each of the one or more blind axial bores each defining an air space between the closed end and the piston.

Abstract: An apparatus for positioning a flexible lance drive device in registry with an opening into a heat exchanger tube sheet includes a flat plate bracket adapted to be bolted parallel to a flange of the heat exchanger. The bracket carries a stub tube fastened to and extending normal to the flat bracket. A rotary drive is removably fastened to the stub tube and has a rotary disc rotatable in a plane parallel to the tube sheet. A slotted box rail has a proximal end clamped to the rotary disc and a linear drive assembly is removably fastened to the slotted box rail. A guide tube collet block assembly clamped to the linear drive assembly removably supports a flexible lance drive and guide tube to guide a flexible lance between the lance drive and a selected one of a plurality of tubes penetrating through the heat exchanger tube sheet.
