A slip molding apparatus (10) for lining a pipe (12) includes a dispense head (20) adapted to engage an interior surface (14) of a pipe (12) and to dispense a lining material, a slip mold (38) pulled by the dispense head (20) and having a leading end (42) and a trailing end (44), wherein the trailing end (44) has a greater diameter than a diameter of the leading end (42), at least one camera (58) disposed on the dispense head (20) to provide a view of the interior surface (14) of the pipe (12), a guide (46) connected to the dispense head (20) and the slip mold (38) for guiding the lining material dispensed by the dispense head (20) about the slip mold (38), and a movable diverter (52) on the slip mold (38) cooperating with the guide (46) to divert a flow of lining material dispensed by the dispense head (20) about the slip mold (38).

An apparatus and a method for coating substrates with washcoats in which a substrate (10) is engaged with a headset (6) of a substrate coating apparatus (1) below a washcoat showerhead (5) are disclosed. The washcoat is discharged from the washcoat showerhead (5) onto an upper surface (12) of the substrate under control of a valve assembly (4) before being drawn through the substrate by use of a vacuum generator (7). The valve assembly (4) comprises an outlet valve movable between a closed state and an open state. The valve assembly (4) creates a pressure drop within an interior of the washcoat showerhead (5) when the outlet valve moves from its open state to its closed state.

A spin caster for spraying a surfacing material upon an interior surface of a vessel includes a spin head configured to rotate about an axis, the spin head including an input port, and a supply line coupled to the input port and configured to convey a first material to the spin head and a second material to the spin head. The supply line comprises a first channel configured to convey the first material to the spin head and a second, different channel configured to convey the second material to the spin head.

A method of lining a pipe with a lining mixture formed from a dry component and a liquid is discussed. The method includes placing the dry component in a dry component surface container located above ground, conveying the dry component from the dry component surface container to a dry component subterranean supply container located underground, conveying the dry component from the dry component subterranean supply container to a mixer located underground, mixing the dry component with the liquid to form the lining mixture, and applying the lining mixture to the pipe with a mixture applicator.

An in situ inspection system and method to inspect a honeycomb body (122) skin in a skinning system. The inspection system includes a line illuminator (148) to generate a line illumination on the skin (136) perpendicular to an axial direction (112) of the honeycomb body travel, and a detector (152) to detect the line illumination scattered from the skin (136) and generate a signal based on the detected line illumination. A controller (184) is configured to receive the signal generated by the detector (152), compare the received signal to a previously stored defect free signal in real-time, and control at least one skinning process parameter based on the comparison. The method includes in situ inspecting the skin (136) and controlling at least one skinning process parameter based on the inspection. In the method, the in situ inspection includes illuminating a line of the skin (136) perpendicular to the axial direction (112) and detecting the illuminated line scattered from the skin (136).

A method for refurbishing a pre-stressed concrete cylinder pipe (PCCP) comprises removing concrete from an existing inner surface of the PCCP at each end thereof to expose a metal core, cleaning the exposed metal core and depositing filler over the exposed metal core at each end of the PCCP to a thickness wherein the filler is substantially flush with the existing inner surface. One or more layers of carbon fibre reinforced polymer (CFRP) liner are applied to the existing inner surface of the PCCP and to the filler at each end of the PCCP. Each layer of CFRP liner conforms to the inner surface of the PCCP and the filler and remains substantially cylindrical with substantially constant diameter along a length of the PCCP with substantially unbent cylindrical ends. After curing all layer(s) of CFRP liner, each terminus of the layer(s) of CFRP liner is sealed.
