A method for preserving cavities by applying a protective layer to the interior of a hollow body. The method uses a mixing nozzle unit coupled to a rotor unit. The mixing nozzle unit is rotated about an axis of rotation and has a mixing nozzle. The mixing nozzle unit has two supply channels for the cavity preservative and for gas for atomizing the cavity preservative. The supply channels run in the direction of the axis of rotation and conduct cavity preservative and atomizing gas separately to the mixing nozzle. The mixing nozzle unit is inserted into the hollow body in the direction of the axis of rotation through an opening in the hollow body. The cavity preservative is discharged in atomized form, and the mixing nozzle unit is rotated about the axis of rotation relative to the hollow body during the discharging or between a plurality of discharging phases.

Manual, automated, or semi-automated programmable tank cleaning nozzle systems, devices and methods for providing safe and efficient methods for breaking up oil, tar, chemical, radioactive, hazardous, or any other liquid, solid, or sludge waste inside storage tanks, ballast tanks, floating roof tanks, void tanks, rail tank cars and the like with nozzles which utilize fluid jets to break up, liquefy, and motivate tank material. The programmable tank cleaning nozzle incorporates two degrees of freedom and can be mounted to existing booms, robotic arms, gantry systems, rigid beams, manways, or any other rigid structure. The programmable tank cleaning nozzle can be a standalone, independent unit or integrated into new designs and/or existing systems. Simplified programming and user interface allowing an operator to remotely operate the system without the need for a camera system. The system is hydraulically controlled and can work in the presence of flammable vapors and dust.

A system is provided for applying a chemical agent within a pipe. The system includes a skid assembly, moveable longitudinally within the pipe and a delivery nozzle carried by the skid assembly and coupleable to an external chemical agent supply. A dispensing tip is carried by the delivery nozzle, the dispensing tip being configured to deliver a controlled stream of chemical agent within the pipe toward an internal surface of the pipe. The dispensing tip is held above a surface of fluid carried by the pipe while at least a portion of the skid assembly is positioned below the fluid surface. The dispensing tip delivers the controlled stream of chemical agent upwardly away from the fluid surface.

A cleaning apparatus includes a nozzle assembly and an arm supporting the nozzle assembly. In some embodiments, the arm includes a first rotatable arm member defining a first axis and a second rotatable arm member defining a second axis and connected to the first rotatable member. In certain examples, the first rotatable arm is rotatable about the first axis and the second rotatable arm is rotatable about the second axis. The cleaning apparatus also includes at least one sensor on the arm and configured to detect a position of the nozzle assembly based on rotation of the first rotatable arm or the second rotatable arm

Disclosed herein is a tool for holding a spray painting instrument, such as a painting gun for painting an internal surface of a pipe. In particular, the inventive tool is ideal for painting the interior of curves and angles in a pipe and is capable of moving through and uniformly painting up to 90 degree angles of pipes or hollow tubes. The tool has a hollow central tube for carrying a spray-painting gun and at least two projections extending outwardly from an outer surface of the hollow tube. A retracting arm assembly is provided on each projection. Each retracting arm assembly includes first and second retracting arms and a corresponding force exertion mechanism. In operation, when the tool is inserted inside the pipe, each retracting arm touches the internal surface of the pipe due to an outward force exerted thereon. The tool is movable inside the pipe and adjusts automatically to different pipe diameters. The tool can be used manually or in an automated fashion to push and pull the paint gun and paint the interior of a pipe.

The present invention relates to a nozzle arrangement and method for removing solids and/or fluids, such as sludge, preferably suspended or contained in fluid, from tanks such as oil/mud-tanks and other similar difficult accessible deposits and tanks/tanks. In preferred embodiments, the nozzle arrangement has a rotating mechanism (8) comprising a primary drive shaft (13) being connected to a pipe section (4), a row of gear teeth (9) fixedly arranged on or formed in lower end of a down pipe (3) on an outside thereof, an angular gear (10), a worm gear (16) arranged to rotate an angled nozzle pipe section (7) at the cleaner head (5) driven by the angular gear, a secondary drive shaft (11) rotatably mounted on an outside of said pipe section (4) and having at one end a gear wheel of the angular gear (10) and at the other end a gear wheel co-operating with said row of gear teeth (9).

Methods and systems for filling a muffler body with a fibrous material prior to completing assembly of the muffler body are disclosed.

The invention relates to apparatuses, machines, systems and methods for periodically washing and/or disinfecting the interior of individual containers having a polygonal base (e.g., rectangular), such as bins of the type used for the used for agricultural commodity collection, storage, and transport (agricultural bins), as well as other types of bins and containers. The systems of the present invention may be operable to automatically and thoroughly clean the interior of such bins.

In the case of a pipe cleaning and/or inspection nozzle, an available camera module can be coupled to a plurality of pipe cleaning and/or inspection nozzles in a simple and cost-efficient manner, and that a secure reliable coupling of the electrical lines is attained. An extension sleeve is inserted, which comprises a high-pressure line section comprising a sleeve loop contact. The sleeve loop contact is fastened in the extension sleeve with a sleeve insulator insert and runs so as to transition into an inner power/signal line within the extension sleeve all the way into an outlet section in the direction of the longitudinal axis. At least one outlet opening is recessed out of the outlet section, and the outlet section opens out into a coupling section, at which means are provided so that the coupling section can be fastened to a camera adapter.
