A method and apparatus is disclosed for additive manufacturing and three-dimensional printing, and specifically for extruding tubular objects. A print head extrudes a curable material into a tubular object, while simultaneously curing the tubular object and utilizing the interior of the cured portion of the tubular object for stabilizing and propelling the print head.

A method is provided for forming an impermeable barrier layer on an inner tire surface of a tire. An assembly is also provided along with a kit for forming an impermeable barrier layer on an inner tire surface of a tire accordingly.

A device for spraying a liquid for use in dye penetration inspection into an inner cavity of a workpiece for making a turbine engine part, the device including a workpiece support, a manifold for spraying the inspection liquid into the inner cavity, a manifold for sucking up and discharging the sprayed inspection liquid, and a mechanism for tilting at least a portion of the support from a substantially horizontal position to an inclined position in which the workpiece is inclined so that the inspection liquid sprayed into the cavity flows under gravity to a zone from which it is sucked up.

A tank cleaning machine comprising a housing having an inlet and a stationary guide diverter disposed within the housing. A gearing mechanism is attached to the stationery flow diverter. A nozzle extends from the housing wherein the nozzle is in fluid communication with the inlet and the nozzle includes an inclined portion extending from a horizontal portion of the nozzle. A drag limiter extends into a hydraulic fluid reservoir to limit the rotation speed of the gear.

A de-ice apparatus is configured to remove ice buildup in containers or other locations by melting the ice using a de-ice component and to remove waste fluid using a vacuum component. The de-ice component causes discharge of pressurized fluid to melt ice. The de-ice component may include a base with guide features configured to engage an opening of the container. The de-ice component may direct a spray of the pressurized fluid into the container to melt the ice. The de-ice component may include a pressure regulator valve to selectively regulate a resulting force of the fluid sprayed into the container, which may enable a user to avoid damaging internal components located within the container. The vacuum component may cause the pressurized fluid to flow through a high pressure nozzle to create a vacuum effect at a suction inlet, which can extract waste fluid and/or other debris from the container.

Pipe inspection systems including a push-cable, jetter, and camera assembly are disclosed. A jetter nozzle may be configured to spin and/or propel the camera head within a pipe or other cavity. A cutter line may be attached to the camera head to clean obstructions. A sonde may be coupled to a camera head to generate magnetic field signals for use with a buried utility locator to locate a pipe or other cavity into which the camera head is deployed.

A holder, a transport device, and a method of manufacturing a container are described. The container comprises a body that extends along an axis and a flange that extends radially to the axis, and the holder comprises one or more fastening elements that are configured to engage one or more of a top surface, a bottom surface, or a peripheral surface of the flange.

An in-situ applicator for applying a composition in a pipe comprises a flow diverter configured to receive a composition and eject the composition from at least one outlet. The applicator also comprises a hollow conical body having a narrow end, a broad end, and an interior surface configured to receive the composition ejected from the flow diverter. The conical body also has a plurality of holes forming a band that wraps circumferentially around the conical body which defines a flow region on the interior surface between the band and the narrow end. The band includes first holes adjacent to the flow region where each of the first holes has a first average diameter and second holes disposed between the first holes and the broad end, each of the second holes having an average diameter greater than the first diameter.

A can coating machine control system includes a coating control signal that functions as a go/no-go signal based on a plurality of monitored conditions such as can in position, vacuum pressure, gun in position, guard in position and speed condition. Local pressure regulation of the coating material in the spray gun is provided along with optional control of the material temperature. Local pressure regulation allows for optional spray weight control based on a wrap number derived from speed and gun spray durations. A CAN to CAN network buffer is provided as well for primary network isolation. A gun control circuit may be used to select specific gun drive signals and to adjust gun drive signals based on real-time feedback of the actual spray duration.
