Abstract: A sprinkler, the intrinsic motions of which are powered by the flow of fluid therethrough emanating from an external source of fluid under pressure. Means contained within the sprinkler cause the expulsion of fluid under pressure, first from one tangentially mounted nozzle, and next through an opposed but commonly aligned tangentially mounted nozzle. The torque generated by the alternating expulsion effects the rotation of the sprinkler first in one angular direction, and then in an opposite angular direction. Buffing means is provided to limit the speed of angular rotation.

Abstract: An improved faucet spout attachment is provided for selectively delivering therefrom either an aerated stream or a spray of liquid. The attachment is inexpensively manufactured and provided by an adapter and a body member. The adapter is shaped to provide thereon both an upstream annular head and a reduced diameter downstream nipple. The adapter's nipple has its exit passageway only in the nipple's longitudinal wall. Two seals are provided on the nipple both up-stream and downstream of the exit passageway. A seal is provided on the adapter's annular head. The body member is axially elongated and constructed to slidingly cooperate with both the head and nipple of the adapter to provide two liquid tight seals at alternate axial positions for the body member. The body member is shiftable axially between two operative positions that establish alternate paths of flow from the body member, one of which produces a spray while the other path leads to a discharge opening in which an aerator is positioned.

One end of an outflow channel is connected to the air exit openings and the other end to a unit delivering air to the fiber material. This unit may be capable of generating flowing air in spurts or continuously. It may be a check-valve type pump or a fan. A filter device is located in the outflow channel, and an air distribution arrangement may be placed behind the unit for delivering air.

Abstract: A device for automatically closing the fine material pan on a manure spreader is disclosed wherein, after being released to a clean-out position, the motion of the fluid endgate is utilized to return the fine material pan to its normal operating position. A lost motion linkage connects the fine material pan to the arm of the fluid endgate. A retraction of the fluid endgate to a transport position through manipulation of a tractor's hydraulic system effects a closing of the fine material pan without the operator having to dismount the tractor.

Abstract: A document feeding apparatus has a deck that is placed at an angle such that the incline of the deck is sufficiently large so as to overcome the friction of documents placed thereupon. The deck has an opening at the bottom thereof through which a vacuum type conveyor extends to engage the bottommost document of the stack of documents to transport the bottommost document generally upwardly. With this feeding of the bottommost document the balance of the documents will remain in position due to the effect of gravity whereas the next-to-bottom sheet will be released from the bottommost sheet since the angle of incline is sufficiently great to overcome the frictional forces acting between these two documents.

Abstract: This hydrostatic atomization paint spray-gun produces A flat jet of paint surrounded by several flat jets of compressed air and comprises at least two complementary jets of compressed air coplanar with the paint jet and converging towards the latter. Thus, the width of the paint jet can be adjusted to reduce it for example to one-half of its width without said complementary jets.

Abstract: A device in combination with a shower head supplied by water under pressure, which device includes a container for storing a liquid or liquids to be selectively mixed with water delivered from the shower head. A liquid delivery path supplies liquid from the container to a location downstream of a water spray forming portion in the shower head, ths path including a valve arrangement for manual control by the shower head user so as to control the delivery and rate of delivery of the liquid. A mixer disc at the downstream location is adapted to be rotated by water jets formed upstream at the spray forming portion of the shower head. The mixer disc is designed to receive, at a central portion thereof, liquid from the liquid delivery path, the action of the revolving disc being such that any received liquid is flung outwardly into the water spray for intimate mixing therewith.

Abstract: Apparatus for feeding dielectric receptor sheets and/or sheet-like carriers for receptor sheets to the ionography imaging chamber of a radiographic system from a nearly upright stack of overlapping sheets has a set of suction heads which are mounted on a first lever pivotally mounted on a second lever. The first lever is repeatedly pivoted relative to the second lever to thereby move the suction heads, which attract a portion of the outermost sheet of the stack below the upper edge face of such sheet, along an arcuate path to thereby flex the upper part of the outermost sheet away from the neighboring sheet. The second lever is thereupon pivoted to complete the separation of the outermost sheet from the neighboring sheet and to introduce the upper edge face of the separated outermost sheet into the nip of two advancing rolls which transport the sheet toward or into the interelectrode gap of the imaging chamber.

Abstract: An airblast atomizer with air swirl vanes has an outlet configured to produce a fuel/air mixture pattern from the fuel nozzle to match an annular combustion chamber formed between an annular inner combustor wall and an annular combustor wall having inlet ends thereof connected to an annular dome for supporting each of a plurality of the fuel nozzles; each of the nozzles including a pair of spaced, large radius slots in a cylindrical outlet wall of the nozzle operative to produce a vortex pattern that will spread the mixed fuel/air pattern from the nozzle to define the major axis of an elliptically formed fuel/air pattern from the nozzle and wherein the remainder of the airblast atomizer nozzle has a reduced radius to conform the fuel/air mixture to the diameter of an outlet swirl chamber from the nozzle to produce the minor axis of an elliptically configured fuel/air spray pattern and wherein the major axis is formed as a chordal line of the combustion chamber to conform the fuel/air mixture pattern from each

Abstract: Apparatus for moving discrete sheets along a first path has a rotary hollow cylindrical foraminous barrel which is located below a portion of the first path and is adjacent to the inlet of a second path along which selected sheets move when a chamber which is rotatable relative to and is located in the interior of the barrel is connected with a suction generating device. The chamber reaches the first path at the inlet of the second path together with the leaders of successive sheets and can be connected with the suction generating device by a solenoid-operated valve which is actuated by a switch which, in turn, is actuated by an adjustable cam on the rotary core which defines the chamber. When the chamber is sealed from the suction generating device, it is connected with a source of slightly compressed air so that streamlets of air which issue from the barrel compel successive sheets to remain in the first path.

Abstract: Pipes, coated with paraffin, scale or otherwise, are cleaned by internally spraying the pipe with a conic sheet of paraffin solvent or scale remover or other fluid. The reaction of the discharge of the sheet of fluid is the propelling force for advancing the nozzle through the opening. An axial jet of fluid clears the tube in front of the nozzle so that the nozzle can advance through the tube. The conic sheet is formed by a pair of sleeves around a mandrel, the sleeves meeting with correlative conic surfaces.

Abstract: A high-pressure liquid-jet gun has a pistol-type housing provided with a valve having an actuation member displaceable between a closed position and an open position to release liquid from an end of the housing. A safety lever is displaceable on the housing between a safety position relatively far from the barrel of the housing and a use position lying against this barrel. A spring urges this safety lever into the safety position. A trigger is pivoted on the safety lever and has a formation which is engageable only in the use position of the safety lever with the actuation member. This trigger can be displaced in the use position of the safety lever between an advanced position with the formation engageable with the actuation member but with this actuation member in the closed position, and a drawn-back position with the formation pressing the actuation member of the valve into the open position.
