Abstract: An irrigation sprinkler with two viscous brakes. The viscous brakes work in conjunction with each other to maintain a low RPM and also to rotate a water stream diffuser. The water stream is first directed toward a deflector that offsets the stream and angles it toward the area to be watered. The offset stream applies a torsional force on the deflector causing it to rotate. The stream is then interrupted intermittently by the diffuser that is rotating at a different RPM. The end result is a sprinkler that rotates slowly and breaks up the stream of water intermittently to create an even pattern of water on the area being sprinkled without using mechanical parts, such as ratchets or gearing. This is desirable for smooth operation and less chance of the operation being interrupted from contamination by dirt, insects, debris, etc. Also, a more random diffusion of the water is obtained.

Abstract: An atomizer for a liquid delivered to an internal combustion engine uses a nozzle positioned such that a substantial portion of the liquid which exits the nozzle will come in contact with the moveable member of an engine induction tract one-way valve. This one-way valve is preferably a reed valve, the moveable member being a reed. The reed or other moveable member has a rapid movement in response to engine operation. When the liquid comes in contact with the rapidly moving reed or other moveable member, it is broken into a mist of relatively fine droplet size. This invention is ideally suited when the liquid is a lubricating oil being delivered to an engine wherein there is minimal fuel in its induction tract or crankcase to thin and spread the lubricating oil to its necessary locations in the engine. It is also useful when the liquid is a fuel, breaking the fuel into smaller droplet size which is more suitable for combustion.

Abstract: The present invention provides a fluid discharging apparatus that delivers fluid in a substantially uniform distribution. The movement of the apparatus is a wobbling motion, preferably combined with some rotational motion.

In certain embodiments, the wobbling turbine then causes the body or housing to wobble.

Abstract: The present invention provides a spray head assembly with a moving spray nozzle that delivers fluid in a substantially uniform spray distribution. The movement of the spray nozzle is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine then causes the spray housing and nozzle to wobble. The spray pattern produced by the wobbling spray housing changes more or less rapidly so that fluid droplets or streams are directed along arcuate paths rather than at a single point. This type of spray distribution pattern is gentler than many stationary patterns and the unique design of the wobble inducing member does not include complex mechanical parts or significant flow restrictions.

Abstract: A hot air pulse generator, particularly for use as a hair dryer, includes a housing enclosing an electric heater and air blower for generating a continuous flow of heated air through a passageway leading to a nozzle. A gently curved baffle arranged across the passageway upstream of the nozzle cuts off 50-75% of the cross section of the passageway and converges the heated air as a high speed air stream toward one side of the passageway. A butterfly valve freely rotatable through 360.degree. on a spindle disposed at an acute angle is located between the baffle and nozzle in the path of the air stream and is continuously rotated by the air flow to effect an intermittent pulsed air output flow through the nozzle.

Abstract: A water toy has a cylindrical deflector mounted on top of an upright hollow pipe that is rotatable about a vertical axis. Pressurized water introduced into the pipe is ejected from a nozzle fluidly interconnected with the pipe wupwardly onto the deflector along a plane which is offset from the deflector axis. The stream of water from the nozzle causes the deflector to rotate which in turn causes water to be thrown off of the periphery of the deflector into an umbrella pattern. If the nozzle has a concentrated spray pattern the umbrella spray is thin and covers a relatively large diameter, and if the nozzle has a fan-shaped spray pattern the umbrella spray is thicker and covers a relatively smaller diameter.
