  • Patent number: 4269354
    Abstract: A water sprinkler develops any of several predetermined patterns of water coverage of regular or irregular shape and of varying sizes. The sprinkler includes first a plurality of pattern-defining apertures which are contoured to pass varying but predetermined amounts of water from a fixed sampling aperture as a sprinkler nozzle rotates in either or both angular directions about a vertical axis.Pattern size is incrementally adjustable in one embodiment by a member having tapered apertures of varying sizes interposed between the fixed sampling aperture and the pattern-defining apertures. Pattern size and shape are finely adjusted by a parallel flow line including a valve for providing small additional or slightly reduced flow volumes. Rounded patterns are effected entirely through the parallel flow line.

  • Patent number: 4269403
    Abstract: Apparatus for successively presenting sheets for inspection by a keyboard operator or the like who must with a both hands otherwise occupied. A support inclined upwardly from a discharge end spaced above the work table holds a stack of sheets to be fed. A feed roller disposed across the discharge end in engagement with the upper side of the stack is energized to advance sheets successively therefrom, while a plurality of frictional retarding elements disposed across the discharge end in engagement with the lower side of the stack prevent the feeding of more than one sheet at a time. The retarding elements are urged against the stack with greater biasing force near the center of the discharge end than at the edges thereof to provide an automatic centering action.

  • Patent number: 4268027
    Abstract: A movable platform supports a stack of sheets, with at least a portion of the stack being in a predetermined feed zone where feeding apparatus engages and feeds the sheets, one-at-a-time, from the feed zone into processing machinery. Biasing means continuously urge the platform toward the feed zone and are responsive to a controller for advancing additional sheets of the stack into the feed zone as the sheets are fed therefrom. A sensor is responsive to removal of sheets from the feed zone to energize the controller for enabling the biasing means to advance the table when sheets are not present in the feed zone and to deenergize the controller for disabling the biasing means and terminating movement of the platform when sheets are present in the feed zone.

  • Patent number: 4268024
    Abstract: A bank note holding method for a counting machine which counts bank notes or the like. These bank notes are placed upon a holder and are clamped with a keep rod. The bank notes thus placed and clamped are forced into abutment contact with a plurality of suction cylinders, which are made operable to make planetary movements, so that they may be sucked and separated one by one by the suction cylinders, thus accomplishing counting operation. For this purpose, the bank notes are arranged uniformly on the holder, and then the keep rod is moved toward the holder by depressing a push button so that the bank notes may be forced into contact with and held upon the holder. The push button is then released so that the holder may be moved to its counting position thereby to start the counting operation. After this operation, the holder and the keep rod are returned to their respective initial positions.

  • Patent number: 4266724
    Abstract: A spray irrigation apparatus including a vehicle which carries a spraying nozzle connected to a hollow shaft of a drum reel, a pipe being connected to the hollow shaft and being wound onto the drum reel. The pipe is dispensed from the reel by means of a reeling guide structure which causes the pipe to move from the reel in a curved path so that the pipe passes from a direction perpendicular to the axis of the reel to a direction parallel to the displacement of the apparatus. That end of the pipe which extends from the apparatus is connected to a water supply station so that the apparatus is supplied with water for spraying onto a field or the like. According to a further feature of the invention, the axis of rotation of the drum reel extends along the direction of movement of the apparatus.

  • Patent number: 4264038
    Abstract: A manually operative atomizer in which a liquid is sucked and pressurized by an atomizer means and is then atomized through a nozzle port. A chamber for pressurizing the liquid is constituted by a cylinder, while an atomizer head is connected to communication pipe which plays also the role of a piston, and is biased in the direction reverse to the pressurizing direction, by means of a spring. The atomizer head is provided with a guiding member adapted to be pressed and moved by an inclined surface of the operation member, so that the atomizer head and the piston or the jetting pipe are moved in the pressurizing direction. As the operation member is released from the depressing force, the spring moves the member back to its original position. Portions of the periphery of the atomizer head other than the nozzle port and the operating portion of the operating member are covered by a cap.

  • Patent number: 4264258
    Abstract: A screw conveyor 14 is mounted on the sub-floor 11a of a chip silo 11, and rotates as a radial arm to convey the chip material into a cover 17 through an inlet opening 18 and to a central discharge shaft 12. The cover 17 rotates together with the screw conveyor, and has a spiral cross-section with its radial step or break disposed on the conveyor axis. The cover radius continually increases in the direction of rotation, to thereby prevent the column of chip material in the silo from exerting a braking force on its side wall.

  • Patent number: 4261511
    Abstract: Pneumatic nebulizer and method for uniformly introducing variable small amounts of flowable liquid into a gas flow to form a stable dispersion having the appearance of a natural fog and consisting essentially of microscopic liquid particles of said liquid dispersed in said gas. The nebulizer comprises a mixing element for introducing the liquid in uniformly fine amounts into the gas flow. The mixing element, which preferably is a replaceable unitary element comprises two contacting members having conforming surfaces which supportingly contact each other over a substantial portion of the surfaces of each to prevent compression therebetween. At least one shallow liquid passage is provided between the members of the mixing element said passage having an entrance in communication with a liquid supply chamber and having an exit orifice in communication with a gas passage to provide at least one stable liquid orifice for metering uniform predetermined amounts of liquid into a gas flowing through said gas passage.

  • Patent number: 4256261
    Abstract: The disclosed stripe-applying ("striping") method and apparatus for applying a curable coating composition (preferably the two-part type) to a paved surface comprises a movable vehicle suitable for traveling over that surface. The vehicle carries a first nozzle for applying a pressurized water spray to the paved surface, a second nozzle for applying an air blast to the paved surface, and a third nozzle for applying the coating composition under pressure to the section of the paved surface previously cleaned by the water spray and air blast. In addition, a glass bead applicator drops a plurality of glass beads onto the coating composition after it has been applied to the paved surface. The two components which comprise the coating composition are heated in a system having selectively operable valves for continuously circulating these components when a striping operation is not taking place.
