Abstract: A system for distinguishing target metal objects from each other in close proximity to each other. The method includes transmitting a first sinusoid signal via a first transmit coil to a first receive coil in close proximity to the first transmit coil; transmitting a second sinusoidal signal at a second frequency and amplitude different from the first frequency and amplitude to a second receive coil arranged in close proximity to the second transmit coil and in close proximity to the first receive coil such that received signals in the first and second receive coils include first and second frequency signals from the other of the first and second transmit coils. The received signals are separated via frequency domain multiplexing. The signals are compared to detect a presence of the target having a signal magnitude different from the first received signal and the received second signal and a known reference point.

Abstract: A rotary nozzle assembly has a hollow nozzle body fastened to a high pressure hose, a tubular shaft rotatably carried in the hollow nozzle body, and a head member fastened to the tubular shaft. The head member has a rounded nozzle head portion and a threaded tubular portion and a central blind bore concentric with the central axis of the tubular shaft. The rounded nozzle head portion has a first lateral port passing from the central blind bore through a side of the rounded nozzle head portion at an offset from the central blind bore. This causes an unbalanced motion of the nozzle assembly on the high pressure hose while the tubular shaft rotates with the head member within the hollow nozzle body. This causes the rotary nozzle assembly, when inserted within a pipe, to follow an orbital path around the inside of the pipe.

Abstract: An apparatus for driving a flexible lance hose into and out of tubes in a heat exchanger tube sheet includes a housing and an upper endless belt drive assembly and a lower endless belt drive assembly spaced apart by a gap for receiving a flexible lance hose therein. One of the drive assemblies is fixed to the housing. The other drive assembly is movable within the housing toward and away from the one endless belt drive assembly. The apparatus further includes a drive motor fastened to the housing configured to engage at least one of the upper and lower endless belts and drive a flexible lance hose disposed in the gap.

IPC: B05B3/04
Abstract: A rotary nozzle having a rotating shaft operating within a cylindrical housing is balanced by allowing passage of a small amount of pressurized fluid to be bled to an area between the outside of the opposite end of the shaft and the inside of the housing where the fluid force acts axially in an opposing direction upon the shaft to balance the axial inlet force exerted by the pressurized fluid. The balance of axial forces is self-regulating by controlling escape of the fluid through a tapered or frusto-conical region between the shaft and housing. A plurality of centrifugal weight segments around the inlet end of the shaft are thrust outwardly against the cylindrical housing to retard rotational speed while pressurized fluid around the centrifugal weight segments provides a fluid bearing between the weights and the housing.

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: 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.

Abstract: A flexible cleaning lance safety apparatus is described as including a tripod support structure located close to an opening into an object to be cleaned. A flexible lance drive is fastened to the support structure for driving a high pressure fluid through a lance to the object to be cleaned. A snout tube is connected between the lance drive and an opening into the object to be cleaned. One or more micro pressure valves on each leg of the tripod support structure is operative to sense a predetermined force applied between the support structure and a support surface supporting the tripod support structure. When the predetermined force is sensed this causes the high pressure fluid to be diverted from the lance and the object to be cleaned to atmosphere.
