Self-propelled, self-powered, propulsion devices as part of pipe lining system adapted to create an internal liner member on a pipe or other tubular structure, the system being the combination of a sprayer apparatus, an umbilical member connected to the sprayer apparatus, wherein the umbilical member supplies no power or communications to the propulsion devices, and a plurality of propulsion devices mounted externally onto the umbilical member in a removable manner. The spraying apparatus and propulsion devices are independently powered and controlled such that each may be accelerated or decelerated as required to maintain the sprayer apparatus at a constant speed during the application process.

The invention relates to a high pressure tool for industrially cleaning and/or machining workpieces by means of a pressurized fluid, wherein the high pressure tool comprises the following: a base body and a flow channel extending between a flow channel inlet and at least one flow channel outlet. In order to provide a high pressure tool of that kind, with which an improved degree of efficiency can be achieved, it is proposed in accordance with the invention that the high pressure tool further comprises a nozzle body on which the at least one flow channel outlet is arranged and through which the flow channel at least partially extends, wherein the base body comprises or forms the nozzle body or wherein the base body is connected or connectable to the nozzle body.

A method for producing a high pressure tool of that kind is further disclosed.

The present disclosure provides a system and method articulating and rotary spray system for fluids that includes a first drive for rotating a mast for different headings and a second drive for rotating a nozzle for different pitches at any time with or without rotation of the mast. The method and system uses a system of interacting gears that rotate a control rod in variable synchronization to control the nozzle pitch relative to the mast heading while the control rod orbits about a center of rotation of the rotating mast along a longitudinal axis.

The present invention relates to a cleaning in place nozzle system (1) for cleaning surfaces of complex shape, comprising a first body part (21) comprising a dry section (22) and a fluid section (23), a second body part (25) coaxially arranged in the first body part, a nozzle part (26) having a nozzle axis (NA), a fluid inlet (24) arranged in the first or second body part and a fluid outlet (27) arranged in the nozzle part wherein the nozzle system is operatively connected to an intelligent control unit (28) for controlling rotational movement of the nozzle part and/or the body parts. The invention further relates to a method for cleaning a container using a cleaning in place nozzle unit.

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.

The present disclosure provides a system and method articulating and rotary spray system for fluids that includes a first drive for rotating a mast for different headings and a second drive for rotating a nozzle for different pitches at any time with or without rotation of the mast. The method and system uses a system of interacting gears that rotate a control rod in variable synchronization to control the nozzle pitch relative to the mast heading while the control rod orbits about a center of rotation of the rotating mast along a longitudinal axis.

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.

A high-pressured rinsing system comprises a base including a liquid reservoir, a rotation motor housing including a rotation motor adapted to rotate a spray wand attached, and extending vertically upward from, the rotation motor housing and base, a linear rail support frame attached the base and including a vertical motor and associated linear rail attached thereto, a cavity mounting plate attached to the linear rail, wherein vertical movement of the linear rail causes vertical movement of the cavity mounting plate over the base; and at least one door and a plurality of side panels mounting to an enclosure support frame, wherein the enclosure support frame is mounted and secured to the linear rail support frame and base to create an enclosure around the spray wand and linear rail.
