Abstract: A method and an apparatus for restricting the areas of contact between components to be plated or coated and liquid solutions containing plating or coating agents, without the use of masking tape. Components made of electrically conductive material are suspended underneath a hood or bell housing which is sized and shaped to receive those portions of the components that should not be plated (or coated). Then the suspended components and the hood or bell housing are fully immersed in a bath of plating (or coating) solution, forming an air pocket under the hood or bell housing. This air pocket surrounds those portions of the components which are not to be plated (or coated) and prevents the liquid solution in the bath from touching those portions. The air acts as a mask that prevents paint or metal from contacting or adhering to surfaces not to be plated (or coated).

Abstract: This invention relates to drink dispensers and particularly to an attachment for a bottle whereby the bottle and the attachment may be placed in an inverted position on a shelf and the contents dispensed as needed. The attachment comprises a tubular member having the same contour as the bottle but slightly larger and adapted to fit over the bottle and to form a base for the bottle when the bottle and attachment are inverted. A partition within the attachment contains a closure for the bottle, so that the closure will take the place of the original cap. The attachment closure has two flexible tubes extending through it. One, the dispensing tube, terminates just inside the closure, and the other, the vent tube, is long enough to extend into the bottle to a point near the bottom thereof. Both tubes lead through an opening in the attachment.
