Abstract: A rotary sprinkler is provided with structure for adjusting the force applied to the impact arm by the impact arm spring. The sprinkler has a laterally directed nozzle cooperating with the arm to rotate the nozzle and an impact arm journaled on a shaft extending above the nozzle. The arm is mounted within a cage extending above the nozzle. The cage includes a pair of arms extending from the nozzle on opposite sides of the shaft and terminating at their upper ends remote from the nozzle in a top plate. A helical spring surrounds the shaft and is secured at its lower end to the arm. A bushing assembly is mounted in the top plate of the cage and receives the top end of the spring. The bushing assembly may be manually adjusted relative to the top plate to vary the force applied by the spring to the impact arm. The sprinkler is mounted in a bucket-like housing positionable within the ground such that the mouth of the housing is flush with the ground surface.

Abstract: A sprayer has a hollow housing with an inlet port and an outlet opening. A cap assembly closes the outlet opening and includes a plurality of sets of discharge orifices with each set exhibiting an individually different characteristic of orifice flow of fluid from the housing interior. The orifice sets are selectively opened to the passage of flow out of the housing and that flow is valved. Different sets of the orifices provide for a fine-spray cone, larger streams and a swirling jet. A porting seal cooperates with a selector plate to enable fluid communication to different sets of orifices and an overall valving assembly also is included. Still further is a stand for the sprayer which supports it, when desired, above a holder or in a manner which enables convenient storage.

Abstract: The disclosed airbrush has an elongated body formed in one piece, as by a molding from plastics material, having an internal cylindrical bore defining a cavity in which other elements are contained. A carrier member assembled within and sealed for a portion of its length to the cylindrical bore supports the point of a needle at a predetermined distance from the forward end of the body and has an internal passageway for the paint. The cylindrical bore is closed at its forward end by a cap threadably attached to the body, inside which is threadably secured a jet through which the point of the needle extends. The carrier member is shaped to provide, in association with the internal bore of the body, a passage for air to the cap and jet region of the airbrush. Adjustment of the longitudinal position of the cap on the body moves the jet with respect to the stationary needle to provide regulation of the amount of paint flow.

Abstract: In a first embodiment a stop having a plurality of ports is connected to and covers an end of a rectangular sleeve. In a region near the stop a narrow wall of the sleeve also has a plurality of ports. A nozzle coupled to a pump provides a flow of air into the other end of the sleeve and the air exits through the ports. With this arrangement, a rectangular sheet inserted into said other end of the sleeve is fluidly brought into registration with the narrow wall and stop. As the sheet is brought into registration fluid injected or drawn through holes in a wide wall of the sleeve is used to force at least a part of the sheet against one of the wide walls and the resulting friction serves to brake the traveling sheet, thereby minimizing impact forces between the sheet, the narrow wall, and the stop. In a second embodiment, similar to the first, the narrow wall and stop include internal projections against which an inserted sheet is registered.

Abstract: An apparatus for lifting packaged integrated circuit parts and feeding them into the input reservoir of a high-speed handler and tester. Parts slide down an input track to the bottom of a fiber-faced belt stretched around two vertically disposed rollers. The leads of the packaged parts are held in frictional contact with the belt fibers which lift the parts to the top of the handler. Efficient operation is accomplished by providing for loading and unloading parts at the same approximate location.

Abstract: There is disclosed a drip-forming device and system for drip irrigation. The device includes a tube and a rod having one end inserted into the tube by an adjustable amount, the rod being formed with at least one longitudinal groove which extends along at least part of the length of the rod and which is in communication with the part of the interior of the tube not occupied by the rod and whose depth decreases progressively away from the said one end over at least part of the length of the groove. With such devices, the output of each device can be simply adjusted to suit the local requirements, irrespective of the size, alignment and supply pressure of the complete irrigation apparatus, by adjustment of the depth of insertion of the rod in the tube. For a constant pressure the water output decreased with increasing depth of rod insertion -- i.e., as the minimum cross-section of the groove at the point of insertion of the rod in the tube decreases.
