The present disclosure provides methods for stabilizing a colloidal dispersion during transport for low defect tolerance applications. The methods involve eliminating fluid interfaces within a dispersion, storing the dispersion in an environment of inert gas, and degassing the dispersion. Several bottle closure devices are described which may be ideal for use with these methods, being able to seal a container filled with a dispersion, permit the removal of headspace and rapidly empty the contained dispersion. In one aspect, the device includes a vented cap and semi-permeable membrane, which allows the passage of gas into and out of the container, and a dispenser nozzle integrated with the device to allow a stored dispersion to be dispensed without removing the device from the container. In another aspect, the bottle closure device includes an attachment point for a removable downtube and dispenser nozzle.

A positioning jig includes a holding portion, a contact portion, and an operating portion. The holding portion holds the cartridge. A portion of the contact portion contacts a writing portion of the pen when the cartridge is held in the holding portion and the pen is held in the accommodating portion. The contact portion is able to rotate with a direction in which an axis of the pen extends as a first rotational axis. The operating portion performs an operation to rotate the contact portion. The contact portion restricts rotation of the pen about the first rotational axis with respect to the contact portion by contacting the writing portion of the pen and positions the pen in a rotational direction about the first rotational axis with respect to the cartridge.

A drywall mud applicator tool includes a body having a wall engaging applicator face, a first end, a second end, a first side and a second side. A first wheel is mounted for rotation on an axle which is secured to the first side adjacent to the first end. A second wheel is mounted for rotation on an axle which is secured to the second side adjacent to the first end. A third wheel is mounted for rotation on an axle which is secured to the first side adjacent to the second end. A fourth wheel is mounted for rotation on an axle which is secured to the second side adjacent to the second end. A first mud containment skirt extends along the first side from the first end to the second end. A second mud containment skirt extends along the second side from the first end to the second end.

Provided herein are methods and systems for the custom-printing of an item including, e.g., a) accepting customer request data for a workpiece and customer request data for a graphic design to cover at least a portion of the workpiece; b) accepting workpiece identifier data from a workpiece database based on the customer request data; c) accepting print design data from a print design database based on the customer request data for a graphic design; d) associating the print design data with the workpiece identifier data; e) printing the print design data onto a hydrofilm portion; f) placing the hydrofilm portion onto a fluid surface in a dip tank; g) applying an activator to the hydrofilm portion to yield an activated hydrofilm portion; and h) dipping the workpiece into the dip tank, whereby the activated hydrofilm portion is bonded to the workpiece as a result of the dipping.

A paint applicator assembly includes a frame having a base. The base has a forward side, a first lateral side, and a second lateral side opposite the first lateral side. A light assembly is supported by the frame. The light assembly includes a printed circuit board having a forward side portion positioned proximate the forward side of the base. The light assembly further includes a plurality of light sources supported on the printed circuit board. The plurality of light sources includes a first light source and a second light source positioned on the forward side portion. The first light source is configured to direct light along a first direction, and the second light source is configured to direct light along a second direction that is different than the first direction.
