Systems and methods for protecting threads of metal pipes while coating the metal pipes with a protective coating are disclosed herein. Innovative metal couplings are used to protect the threads while a protective coating is applied to the metal pipes. The couplings are reusable and result in multiple efficiency improvements over previous methods and systems. Benefits include elimination of plastic caps and reduced waste, improved flowthrough in the powder coating process, more efficient thermo transfer in the thermal chamber, and an increase in the overall capacity of the powder coating operation.

Coat-in-place assemblies and methods to provide an aesthetically pleasing sprinkler assembly. A coat-in-place assembly includes a sprinkler body having a proximal portion and a distal portion, a thermally responsive trigger disposed adjacent the distal portion; and an escutcheon centered about the distal portion of the sprinkler body to define a void between the sprinkler axis and the escutcheon. A coating-inhibiting-cap encloses and protects the thermally responsive trigger between the sprinkler body and the cap. The cap extends into the void and is radially spaced inward relative to the escutcheon so as expose surfaces of the escutcheon for coating.

An apparatus for applying masking tape to a surface is provided that includes an upper portion and a bottom portion attached to the lower portion, where the upper portion includes a pair of opposing edges separated by a top surface having a basin therein for receiving a placement pad, and a side surface having an inner plank and an outer guide plate, the lower portion includes a masking tape mount oriented relative to surfaces of the opposing edges and top for tape to be passed in a sliding arrangement from the tape mount and along the surfaces of the opposing edges and top.

A marking gun having a marker container, a propellant canister, a supply tube, an expulsion chamber, and an attachment coupled to the expulsion chamber. The marker container is coupled to the expulsion chamber by the supply tube, and the propellant canister is coupled to the expulsion chamber. The marking gun is configured to expel the marker from the expulsion chamber. The attachment comprises a stencil, an elastic pointed tip, a housing, a screen, a magnet, one or more entry holes, or a combination thereof.

The disclosure presents templates that can be useful in construction. Embodiments of the templates include a face, and two or more indicators. The indicators are located at one or more predetermined intervals on the face, and each indicator defines a window. Each window is of a predetermined length, and each indicator is coded to indicate that each indicator is located at one of the one or more predetermined intervals.

A method for selective paint application to a component includes applying a photoresist masking to the component and applying a template mask to the component on top of the photoresist masking. The method includes curing at least a portion of the photoresist masking on the component, removing an uncured portion of the photoresist masking from the component, and applying at least one layer of paint to the component. The method further includes removing the photoresist masking from the component.

A coating device includes an upper stage, a lower stage and a spraying part. The upper stage masks an upper surface of a display panel. The lower stage masks a lower surface of the display panel. The spraying part sprays ink to a side surface of the display panel. The side surface of the display panel is exposed between the upper stage and the lower stage. The coating device includes the upper stage and the lower stage, so that the coating device may form a coating layer of uniform thickness by precisely spraying ink. In addition, a cross-section of the coating layer may be precisely formed having specific shape such as an L or C shape. A display apparatus having high light usage efficiency and reduced light leakage may be provided by using the coating device.
