Abstract: A spreader for feeding and uniformly distributing grain in a bin. The spreader has a hopper to receive the incoming grain. A screw mounted in the hopper evenly spreads the grain and propels it into a chute whose discharge mouth is normally closed by a spring pressed gate, or valve. A rotary thrower blade, mounted below the chute, aids the chute to distribute the grain generally radially and downwardly uniformly in the bin. The screw, the discharge chute and the thrower are driven as a unit by a single shaft, mounted coaxially in the hopper, and rotated by a motor mounted externally of the hopper. The pressure of grain movement propelled by the screw opens the chute gate allowing grain to pass to the spreader.

Abstract: A high-pressure fluid jet valve assembly is disclosed utilizing a double-acting piston actuated by a spool valve to reversibly actuate the valve stem. The valve stem selectively gates high-pressure cutting fluid through a seat arrangement directly into an output expansion section. Directly coupled to the expansion section is a valve head holding a jewel holder used to shape the high-pressure fluid beam for cutting purposes. The valve seal, stem and seat arrangement are designed to prevent leaching of the stem by the effect of high-pressure water, yet allow the cycling time in the order of 25 milliseconds.

Abstract: An improved water sprinkler of the arm driven type which has a reverse drive arm movable into the water stream emerging from a replaceable nozzle, to provide rapid reverse rotation of the sprinkler. The improvement lies in a novel nozzle structure which limits movement of the reverse drive arm by an amount dependent upon the nozzle size, thereby resulting in substantially the same reversing force regardless of nozzle size.

Abstract: A center pivot irrigation system has first and second auxiliary nozzles, or end guns, alternately operable for irrigating substantial portions of corner regions. The system includes a main pipeline sprinkler having main fluid discharge nozzles for irrigating a central, generally circular area, and the end guns are connected to the main pipeline sprinkler and draw irrigation fluid from it. When a corner is approached, one of the end guns is actuated while maintaining actuation of the main fluid discharge nozzles. A short period of time thereafter, the second end gun is actuated, and the pivotal rate of the main pipeline sprinkler is reduced to zero. At this time the main fluid discharge nozzles and the first end gun are closed, thereby providing all of the fluid from the main pipeline sprinkler to the operating end gun. After a predetermined time period, the second end gun is inactivated, the first gun and the main nozzles are reactivated, and the system is pivoted to a new orientation.

Abstract: A pneumatic microcapillary nebulizer adapted to accept a supply of flowable liquid, such as water, and reduce the liquid to an ultrafine dispersion of particles in a propellant gas, such as air. The microcapillary nebulizer comprises a mixing element having a liquid conduit comprising a microporous capillary element having a multiplicity of liquid passages and exit orifices, a gas conduit having a gas orifice and a filming-surface having an edge comprising said gas orifice and communicating with said liquid exit orifices. All the liquid flowing to said filming surface must pass through said capillary element wherein it is retained in the absence of external forces and whereby it may be rendered substantially free of undesirable solid impurities of microscopic size or larger.

Abstract: A fitting coupled to a water source, comprising an orifice, means for regulating the quantity of water passing through said orifice, an abutment for water passing through said orifice, and laterally displaced water outlet means.

Abstract: An airbrush of the double action type has an elongated unitary body having an axial passage for longitudinal movement of a needle supported therein. The rear end of the needle is carried by a guide slidably supported in the axial passage and normally urged by a spring in a direction such that the tapered front of the needle enters and closes the jet. A finger-operated lever formed of plastic and shaped to provide a "living hinge" is supported in the body and arranged to engage the guide and move the needle against the action of the spring to control paint flow, and at the same time to open a valve to allow entry of compressed air or other substance under pressure. The maximum paint flow at the fully-operated position of the control lever is predetermined by adjusting the longitudinal position on the body of a closure cap which limits the movement of the guide. The airbrush has a minimum number of easily assembled parts and features a relatively simple paint-to-air seal disposed within the axial passageway.

Abstract: An article for the slow release of volatilizable substances, such as deodorizers, insecticides, repellants and the like, the article being formed from opposed outer and inner wall members joined along their peripheral portions to define a central reservoir portion for receiving and confining a volatilizable substance. The outer wall member comprises a non-porous flexible polymeric sheet material which does not permit bulk flow, but allows molecular diffusion therethrough. The inner wall member comprises an impermeable barrier layer. Another barrier layer is releasably bonded to the outer wall and prevents escape of volatilizable substance until its removal at the time of desired use. In a further aspect, a strippable adhesive layer is bonded to the outer surface of the inner wall impermeable layer and removal of the strippable layer enables adhesive bonding of the article to environmental surfaces.

Abstract: Foam is produced when a reservoir is deformed by squeezing. When pressure is applied to the reservoir, a vent passage is sealed by a flexible washer, while liquid is forced up a tube and through a passage in a cylindrical member to a region at the top of that member. Air is forced through another passage and swirls into the same region to mix with the liquid. As the pressure of the mixture increases, a ball valve located above the region, is caused to open which allows discharge of the mixture. When the pressure is released, the valve is sealed and suction pulls the washer away from the vent to allow air back into the reservoir.

Abstract: A vehicle conveyor suitable for a car wash is described wherein tire-engaging rollers are attached to a continuous chain positioned underneath the path of the vehicle. The rollers are normally carried by the chain in a nonengaging position below the vehicle track. Then, when movement of the vehicle is desired, a coin-actuated control or a manual control is actuated to move a cam into operative position to cam one of the rollers upwardly through a slot onto the top surface of the vehicle track where it engages the vehicle's tire. The roller subsequently drops through a slot proximate the end of the conveyor course.
