Abstract: An automatic larvicide dispensing apparatus which is actuated by weather conditions. A container for holding liquid larvicide has a sealed cylinder disposed therein and a piston reciprocally disposed within such cylinder. This piston is biased to one position within the cylinder and is movable to a second position. A leather strap, or other actuator having similar properties, allows the piston to move to the first position thereof when weather is wet and shrinks to push the piston to the second position when weather conditions are dry. The cylinder has one-way valves associated therewith to act as a pump for loading the cylinder during wet conditions and dispensing the larvicide from the cylinder during dry conditions.

Abstract: This invention relates in general to a theft protection device for hand or shoulder carried articles, such as cameras, purses, etc., and more specifically to at least one predetermined force responsive attachment device, which has one component attached to the article alone, and the other component attached to the carrying straps, and both components are adapted for releasable engagement with one another, upon the application of a predetermined amount of force.
