    Abstract: An abrasive solution for finishing a metal part is provided. The abrasive solution includes abrasive particles suspended in a solution. The abrasive particles are configured to abrade a surface of the metal part. The abrasive particles are substantially non-responsive to a magnetic field. The abrasive solution also includes magnetic particles suspended in the solution. The magnetic particles are configured to respond to a magnetic field by aggregating together such that a local flow pattern of the solution changes in response to the aggregated magnetic particles.

    Abstract: Spray gun reservoir components are disclosed. The spray gun reservoir component includes a liquid outlet and an outer face, and defines a centerline plane and an attachment plane. The liquid outlet surrounds a longitudinal axis. The outer face extends away from the liquid outlet. The centerline plane passes through the longitudinal axis. The attachment plane is defined orthogonally to the longitudinal axis and the centerline plane. The outer face further comprises a retention feature extending away from the centerline plane and generally parallel to the attachment plane. In some embodiments, the spray gun reservoir component further comprises a bearing surface formed on the outer face along the attachment plane to engage with a corresponding bearing surface on a liquid spray gun attachment point, with the bearing surface comprising the retention feature.

    Abstract: The invention relates to a method for preparing a pipe for a continuous spray lining process, the method comprising the following steps: providing an inflatable packer (3); providing an expandable sleeve (4) with a conformable backing layer (5) and an adhesive layer (6); wrapping the expandable sleeve around the packer with the adhesive layer facing the outside; inflating the inflatable packer until it reaches a first diameter (D1), wherein the first diameter is smaller than the inner diameter (d) of the pipe section, thereby expanding the stretching sleeve, inserting the inflated packer with the expanded sleeve into the pipe (1, 2) until it reaches the pipe section to be sealed; and further inflating the packer until it reaches a second diameter (D2), thereby further stretching the expandable sleeve; wherein the second diameter is reached when the expanded sleeve touches the inner diameter (d) of the pipe section.

    IPC: B05B7/24

    Abstract: A spray gun reservoir connector system. The system includes a reservoir lid, a spray gun inlet, and complementary first and second connector formats. The first and second connector formats are provided with one of either the lid or the spray gun inlet. The first format includes a plurality of retention structures each defining a capture region. The retention structures are collectively arranged in a circular pattern. The second format includes a plurality of lock structures each including a shim body configured to selectively interface with the capture regions. The connector formats are configured to provide wedged engagement between the lock structures and corresponding ones of the retention structures upon rotation of the spray gun inlet relative to the lid. The lid may include a spout. The retention and lock structures are radially spaced outside of the spout, and the spout may have an inner diameter of not less than 22 mm.

    Abstract: A spray gun reservoir connector system. The system includes a reservoir lid, a spray gun inlet, and complementary first and second connector formats. The first and second connector formats are provided with one of either the lid or the spray gun inlet. The first format includes a plurality of retention structures each defining a slot. The retention structures are collectively arranged in a circular pattern. The second format includes a plurality of lock structures each including a stem and a button head configured to selectively interface with the slots. The connector formats are configured to provide wedged engagement between the lock structures and corresponding ones of the retention structures upon rotation of the spray gun inlet relative to the lid.
