Abstract: A fluid-handling device, such as a lawn-and-garden water sprayer, includes a plurality of elastic bladders that are filled via a common manifold. To ensure that all the bladders can be filled without one bladder over expanding or emptying into another one, the fluid-handling device includes a plurality of limit valves in one-to-one correspondence with the plurality of bladders. When filling the bladders, the limit valves are open to convey fluid from the manifold to the bladders. In some examples of the invention, each individual limit valve will close automatically in response to its respective bladder having reached a predetermined expanded length.

Abstract: The leg mounted scent dispenser distributes liquid scent to mask human scent or to deposit a tangle free and consistent scent trail. The dispenser assists hunters in capturing game with weapons and cameras alike. The dispenser includes straps for attaching to a boot and to the lower leg of a person. The boot level strap connects to a canister filled with a scent of the hunter's skillful choice. The canister communicates with a drip valve, or alternatively a pump, that discharges a small portion of scent with each time the boot lands. The person regulates the desired scent flow and walks to a stand or tracks the game. Once at a stand or having taken the game, the hunter turns off the canister and removes the present invention for storage.

The diffuser unit is contained in the housing, and diffuses the water and the foam to engage with the blown air from the free end of the discharge tube of the conventional back pack blower so as to be propelled by the blown air out of the housing.

Abstract: A hand-portable spreader blows particles, such as salt or sand, over an outdoor surface to increase friction. The spreader has a grip and accepts an extension cord to power the blower motor. The motor drives a vane impeller mounted in a housing and connected to a nozzle, similar to a leaf blower, but the intake to the impeller is arranged to suck up particles from a storage chamber. The air passes through the particles in the storage area and then through an orifice, where the air stream velocity increases and particles are picked up and levitated up into a conduit that passes to impeller. After passing through the impeller, the particles and air are ejected from a nozzle to scatter the particles over a surface such as a street or sidewalk to melt ice and snow, for use as a friction (anti-slip) agent.

Abstract: An apparatus for adapting a blower system to the dispersing of liquid material is partially housed within an extension tube of a portable blower and includes a pressurizing tub with an inlet for accepting airflow discharged by the blower.
