Multi-stage dispensers

摘要

A multi-stage floatation dispenser for carrying a ballast, which may be a non-water consumable dispersant and at least one water consumable dispersant wherein the weight of the water consumable dispersant decreases as the water consumable dispersant is consumed with the weight of water consumable dispersant and the non-water consumable coordinated with the flotation capacity of a flotation dispenser to provide for either a two stage or a three stage dispensing mode.

主权项

1. A multi-stage flotation dispenser for floatingly delivering one or more dispersants to a body of water comprising;
a housing having a central axis; a cylindrical sleeve having a cylindrical opening extending along the central axis; an annular flotation chamber located in the housing to provide buoyancy to the flotation dispenser; a first container for a water dispersant with a water dispersant located therein that retains its mass when in contact with the body of water, said first container located in the cylindrical opening; a second container for a further water dispersant with a further water dispersant therein that losses its mass to the body of water, said first container and said second container located along the central axis with the first water dispersant and the further water dispersant having a specific of gravity greater than one, said further water dispersant having a weight exceeding a weight of the first container and the first water dispersant with the first water container with the first water dispersant and the second container with the further water dispersant either having a total weight less than a buoyancy force of the flotation dispenser or a total weight greater than the buoyancy force of the floating dispenser.
