Abstract: A container suitable for holding a fluid includes a body defining an interior volume and having a torso portion having a substantially square-shaped cross section, a shoulder portion joined above the torso portion and including a plurality of shoulder walls that define a substantially square cross-section, and a base portion, which may have a substantially square or octagonal cross section. The container body may be formed with indentations at each of its four bottom corners that are shaped to give the container relief from detrimental piercing contact with the lugs that are provided in the bottom of some square retention buckets used on commercial paint shakers. The body may be made substantially or entirely of polyethylene terephthalate. The container is particularly suited for colorants and pigment dispersions for tinting coatings and for shaking colorants and pigment dispersions prior to dispensing into a tinting machine.

Abstract: A method and apparatus of for mixing a tinting concentrate disposed in a container. The container is held inside a larger bucket by a base insert and a top insert. The bucket with the container secured therein is clamped to a table of a mixing apparatus. The table is then vibrated, thereby mixing the tinting concentrate.

Abstract: An adjustable shelf for a paint colorant dispensing station comprises at least two platforms rotatably mounted on a pair of brackets. A pair of stops restrain the rotation of the shelf between two positions. One of the platforms is substantially horizontal and disposed beneath a dispensing head in one of the positions. The other platform is substantially horizontal and disposed beneath the dispensing head in the other of the positions. Each platform is adapted to hold a paint can. Each stop is adjustable by rotating the stop relative to the shelf. The rotation causes a threaded rod to extend from or retract to the element that supports the stop. A locking mechanism is provided to selectively restrain the shelf against rotation when the shelf is in one of the two positions.

Abstract: Corrosion of metal surfaces in cooper or copper alloy cooling water systems is inhibited by the addition of small amounts of aromatic triazoles and iminodicarboxylic acids or derivatives thereof to the cooling water system.
