Abstract: A fluid dispensing device which enables one or two fluid mixture components to be selectively or simultaneously dispensed via manually operable selection and actuation means. A dispenser which incorporates a body, one or more fluid storage and delivery channels, a selection and actuation means operable to cause the release of a quantity of a one or more stored fluid, and a base or work station adapted for upright storage, refilling, and use of the said dispenser, are disclosed herein. One or more said fluid storage and delivery channels may be engaged by said control means in order to eject one or more fluids. The said dispenser includes a ratio-metric scale system which permits ratio based selection of two fluids for ejection in a first mode of operation, and permits selection of a particular volume of a fluid for ejection in a second mode of operation.

Abstract: A stiffened, collapse resistant, pleated filter which is formed from a tube of filter media having an open end, a closed end, and an interior volume, and includes a section of helical, circumferentially arranged pleats, and may also include a support element. The said pleated section describes a collapsed ruled hyperboloid. The said filter may include one or more layers of filter media material. The current invention does not require any notching or pre-forming of the said pleats, as all the said pleats are formed concurrently by a controlled twisting of an initial filter media tube.

Abstract: A fluid dispenser which enables one or two liquid mixture components to be selectively or simultaneously dispensed via a manually operable selection and actuation means. The said dispenser incorporates a body, one or more fluid storage and delivery channels, a selection and actuation disc operable to cause the release of a quantity of a stored fluid, as well as articulation and clamping means which support the said disc. One or more of the said fluid channels may be urged by said disc via cams to eject a fluid or fluids from corresponding cartridges. The present device provides a scale and pointer system which permits selection of a particular volume of a fluid for ejection in a first mode of operation, or selection of a specified mutual proportion of two fluids for ejection in a second mode of operation.
