|20140109936||METHOD AND APPARATUS FOR CLEANING ELONGATED TUBES - A system and method for cleaning elongated tubes is presented. An apparatus for cleaning elongated tubes includes a cart, a lance, a pressure sensing device and a propulsion device. The lance sprays material into elongated tubes to clean the elongated tubes. The cart supports the lance while the cart is moves in a rail in a forward direction and in a reverse direction. The pressure sensing device is located in the cart detects a pressure exerted on the cart as the cart moves in a forward direction in the rail. The propulsion device, upon the pressure sensing device detecting a pressure crossing a threshold value, propels the cart in the reverse direction for predetermined distance or time before again propelling the first cart in the forward direction.||04-24-2014|
|20130118529||METHOD AND APPARATUS FOR CLEANING SURFACES - An apparatus and method for cleaning a surface. The apparatus includes a frame having wheels and a handle extending outwardly therefrom. A disc plate assembly is mounted on the frame for rotation about a first vertical axis and a nozzle assembly is mounted on the disc plate assembly for rotation about a second vertical axis. The disc plate assembly is rotated at a lower speed than the nozzle assembly. Separate pneumatically-operable motors drive the wheels, the disc plate assembly and nozzle assembly. A skirt extends downwardly from the frame and outwardly from nozzles on the nozzle assembly. The nozzles may be raised or lowered relative to the surface to be cleaned. Fluid is delivered from a fluid source to the nozzles and a vacuum port is provided on the frame to enable dirty fluid to be removed from a chamber bounded by the skirt.||05-16-2013|
|20130042894||APPARATUS, SYSTEM AND METHOD FOR CLEANING HEAT EXCHANGER TUBES - A hose reel assembly, system and method for cleaning tubes, particularly heat exchanger tubes, which system includes independently rotatable inner and outer drums. The inner drum is rotated in a first or second direction by a first motor assembly to wind a hose disposed in a gap between the drums, off of or onto the inner drum. A second motor rotates the outer drum causing rotation of a nozzle on the hose about the hose's longitudinal axis and at speeds of about 100 to about 1600 rpm. The nozzle delivers a water jet at pressures of up to about 55,000 psi to cut through deposits in the bores of the exchanger tubes. The nozzle is mounted on an indexer movable within the heat exchanger and a camera and joystick on a remote console enables an operator to view the cleaning operations and manipulate the nozzle in relative safety.||02-21-2013|
|20120103368||METHOD AND APPARATUS FOR CLEANING ELONGATED TUBES - Methods, apparatus and other embodiments associated with cleaning elongated tubes are presented. An apparatus includes a rail, a lance a cart and a door. The rail has a left side and a right side. The lance sprays material into elongated tubes. The first cart supports the lance the cart can move in the rail in a forward direction and in a reverse direction. The first door is movably attached to the rail and moves to an open position when the cart moves in the forward direction and moves to a closed position when the cart moves in the reverse direction.||05-03-2012|
