Oscillating rotation is achieved via a drive train that includes a trip spring that is drivable between first and second positions for reversing the direction of nozzle rotation. The sprinkler also includes: a variable trajectory nozzle; secondary opening adjacent the variable trajectory nozzle; an automatic break up screw configuration; a substantially constant speed turbine assembly; a bypass stator; a reversing cluster gear planetary drive with a uni-directional turbine; an overcenter reversing mechanism; a nozzle base clutch; an adjustable arc mechanism, solid arc limit stops, a snap ring installation method and an adjustable pilot valve which uses visual indicia.

Abstract: A feed system for a rotary coating atomizer formed from two opposed coaxially mounted rotating atomizer assemblies consists of a cylindrical, hollow distributor mounted coaxially between the atomizer assemblies. The distributor contains one or more distributor feed holes formed in each opposing side in proximity to the adjacent atomizer assembly. A hollow axle passes coaxially through the distributor and the atomizer assemblies, and contains one or more axle feed holes beneath each distributor, so that when the coating is fed through the hollow axle it enters the distributor through the axle feed holes and exits the distributor through the distributor feed holes onto the atomizer assemblies.

Abstract: An aerosol dispenser assembly (1) has a container (2) holding a liquid product and a liquefied gas propellant for propelling the liquid product from the container, the propellant being present in a quantity of at most about 25% by weight of the contents of the container (2). A valve (4) is attached to the container (2) for selectively dispensing the liquid product from the container (2) as a mist. The assembly (1) is configured such that the mist has a small particle size, is dispensed at an expeditious rate, and very little product is retained in the container (2) when the propellant is depleted.

Abstract: A spraying gun includes a gun body, a water guide pipe, a water control bar, and a water control switch. Thus, the driven portion of the water control bar is pushed by either one of the engaging portions of the eccentric urging face of the water control switch, so that the water control bar is moved in the receiving space of the water guide pipe step by step so as to control the water flow in the water guide pipe in a multi-stage manner, thereby facilitating the user regulating the water flow rate of the spraying gun so as to save the water source.

Abstract: An irrigation spray stake for plants grown in pots utilizes an elongated stake member having an upper extremity and a lower extremity adapted to be inserted into the soil, with a spray head adjacent the upper extremity of the stake member, with an arrow or similar feature along the stake member between the upper and lower extremities to indicate the predetermined spraying direction of the spray head. The arrow or similar feature may be formed as a plate which rests against the surface of the soil, with the back edge of the plate resting against the inner surface of the nursery pot into which the stake is extended.

Abstract: A spray head for a faucet or the like has a wand body defining a flow path from an inlet to first and second outlets. Diverter seats are provided so a face seal on a diverter spool can direct flow to the first or second outlet. The spool is positioned by a trigger acting on cam surfaces formed on a toggle. A spring biases the toggle to one of two stable states. Movement of the spool by the trigger causes the toggle to change states so subsequent actuation of the trigger causes the spool to move in the opposite direction. The wand body also has a pause button that reciprocates in a chamber that is part of the flow path. The chamber includes a valve seat and the pause button has a spool having a face seal that is engageable with the valve seat to shut off flow through the spray head. A return spring causes separation of the pause button's face seal upon release of pressure on the pause button.

Abstract: A unitized mat to facilitate growing woody plants includes at least two polymeric material layers, an inlet for delivery of fluid, and at least one outlet for dispensing fluid into an area covered by at least one layer. There is an opening in the layers through which the plant extends along with an installation seam with overlapping ends. The mat includes perforations, aligned or off-set, for fluid outlets and may be used in a container, such that a polymeric material layer covers the surface thereof. Flexible extension flaps adjust for container size and shape. The mat is removably affixed to a container and/or can be fed by a water-filled container with a polymeric material layer integral with the container. The mat may be used for woody plants in a row, such as orchard applications. Extension flaps provide continuous cover around and between plants, and perforations provide anchors for fixable positioning.

Abstract: A showerhead as described herein includes a translucent hollow body having a fluid chamber, and a fluid distribution element configured to release fluid contained in the fluid chamber. The fluid distribution element includes a plurality of raised concentric rings having peaks that serve as the fluid release points. The fluid distribution element contains a number of fluid ducts that are specifically shaped to transport the fluid from the fluid chamber toward the fluid release points. The translucent nature of the showerhead creates an optical lens effect that illuminates the showerhead and the water droplets formed by the showerhead. The illumination of the water droplets creates a pleasant showering experience for the user.

Abstract: An expandable fire-fighting fluid container is arranged for receiving a fire fighting fluid. The container is comprised of end walls, a bottom between the end walls, and movable side walls connected to the end walls and the bottom with expandable seals. Actuators are attached between the side walls and the end walls. The actuators are powered by an engine attached to the container. The side walls are retractable inward for reducing container width for traveling on public roads, and expandable outward for increasing fluid capacity at a fire site. A pump is attached to the container for pumping the fluid to douse a fire.

Abstract: There is provided a reversible spray tip unit for an airless spray gun having an axially rotatable cylindrically shaped turret member with the spray tip nozzle arranged in a diametric fluid bore therein, the turret member being disposed in a complementary shaped bore of a housing and arranged transverse to the flow of paint, and a saddle seal received axially in the housing and having a cylindrically shaped sealing face mating with the cylindrical shape of the turret member at the diametric fluid bore housing the spray tip nozzle. Upon assembly of the disassembled reversible spray tip unit, the saddle seal is quickly inserted into the housing and accurately oriented so that its sealing face is aligned with the cylindrically shaped bore in the housing for the turret member by means of an insertion/orientation tool which is adapted to be keyed to the fluid bore of the saddle seal.

Abstract: A fuel injector has a chamber between a valve body and a plate in which a plurality of through holes are formed. The chamber has a diameter larger than that of an opening of the valve body. The through holes are opened at an outer chamber area shaded by the valve body are distanced from an outer wall of the chamber more than a diameter of the through hole. Fuel flowing along an inner inclined surface of the valve body turns to the through holes and flows into the through hole from all directions and collides with each other at inlets of the through hole. Therefore, injected fuel has a lot of turbulences and is finely atomized.

Abstract: Disclosed is a chemical additive dispensing device for use with a station of a sprinkler-based irrigation system that includes a fluid diversion housing and a container for storing a chemical additive. The fluid diversion housing includes an in-flow channel formed therein that is in fluid communication with an input port and the container. An out-flow channel is also formed within the fluid diversion housing and is in fluid communication with an output port and the container. In operation, the container fills with fluid from the in-flow channel such that the fluid mixes with the chemical additive. Once the container is filled with fluid, the mixture of fluid and chemical additive is diverted through the out-flow channel of the fluid diversion housing to the outlet port such that the fluid chemical additive mixture is distributed to the rest of the irrigation system and particularly through sprinklers onto a lawn and/or plants.
