Abstract: Apparatus for producing finely divided liquid particles which includes two chambers having means for conveying liquid from one chamber to the other and back again to the first chamber in response to a means for producing a pressure differential between the chambers. A hollow apertured plenum chamber having a smooth outer surface is positioned so that the liquid impinges on its exterior surface as it traverses its flow path. Gas is supplied under pressure to the interior of the plenum and ruptures the thin film of liquid at the aperture to produce the finely divided liquid particles.

The bins are provided with guide organs and each bin can be moved so that its guide organ protrudes into the track so as to guide a sheet into a bin. In the transport track the sheets are transported by means of belts running around a vacuum holddown device so as to hold the sheets onto the belts.

Abstract: A pair of colinearly movable, reciprocating paddles for bumping the side edges of sheets flowing serially along a feed path is disclosed. The sheets travel between the reciprocating paddles in a direction generally perpendicular to paddle movement. The paddles jog the sheets into a correct alignment position to establish registry between the sheets and, for example, the plate cylinder of an offset printing press supplied with the sheets. The distance between each paddle and the sheet feed path centerline can be adjusted during reciprocating movement of the paddle to meet registry requirements. A disengagement mechanism permits separate use of either paddle.

The apparatus for extracting a desired number of sheets comprises an operational mechanism incorporating a solenoid and associated members which is operated in cooperation with the action of said separator which separates the desired number of counted paper sheets from the remaining paper sheets so as to move said paper-pressing bar in a direction away from said holder and which can be reset to its original state.

Abstract: A center pivot irrigation system has first and second auxiliary nozzles, or end guns, aternately operable for irrigating substantial portions of corner regions. The system includes a main pipeline sprinkler having main fluid discharges 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: An apparatus for dispensing liquid including a flexible container for storing liquid, a closure connected to the container, a cap rotatably connected to the closure having an orifice therein, a film-forming post connected to the closure with an orifice therein alignable with the orifice in the cap, a stem projecting upwardly from the closure for conveying liquid to the film-forming post, and a dip tube connected to the stem for conveying liquid from the container to the stem.

Abstract: Disclosed is a shower head dispenser for bath oil and the like which includes a body member with an axial bore adapted for insertion between a shower line and a shower head. The body member has two longitudinally spaced apertures or transverse bores in its side wall which communicate between the axial bore and a detachable oil container. It has a dam extending transversely across the bore. One of the apertures intercepts the axial bore at the crest of the dam, and the other aperture intercepts the axial bore upstream of the dam. The oil container has an integral valve stem thereon which seats in the end of the downstream transverse bore, and metering is achieved by rotation of the container. When water passes through the axial bore of the body member, the greater pressure at the upstream bore or aperture forces oil out of the container through the downstream bore or aperture into the axial bore at the dam, where it mixes with water enroute to the shower head.

Abstract: A winching and traction intensifying device for extricating an immobilized rubber tired vehicle. The device has a traction intensifying portion secured to a driving tire and an anchoring portion connected to the traction intensifying portion. A corresponding non-driving tire secures the anchoring portion through the weight of the vehicle itself to establish a necessary fixed point for the winching device while, simultaneously, the traction intensifying portion is coupled to the driving tire.

Abstract: A spray and aerator faucet appliance is provided by a construction wherein the selection of water discharge is effected by merely rotating the water discharge head portion of the appliance until the desired water discharge from the appliance appears. Selectivity is achieved by providing two abutting internal parts, each with a flow passageway located eccentric of the axis of the appliance, with seal means for the eccentric flow passageway provided between the abutting parts, for permitting selection either of flow only through the eccentric flow passageways when aligned, or no flow through the eccentric passageways when not aligned, thereby permitting discharge of flow through an alternate flow path. Each of the two abutting internal parts is locked internally of the appliance to one of the two portions of the appliance between which relative rotation is effected by rotating the discharge head. All parts of the appliance, except for the seals and screens, are inexpensively executed in plastic.
