  • Patent number: 4718606
    Abstract: A method and device for spraying agricultural crops where a liquid, for example a fungi-insecticide, growth regulating substance or fertilizer, is atomized in a conical or flat spray plane (24), wherein the spray mantle (24) is partially interrupted so obtaining an asymmetrical spray picture whereby an accurate and even concentration can be achieved. An atomizing body (9) is rotatabe around a stationary part (1) formed as a hollow cylinder, whereby a groove (14) connecting with the cylinder space (3) is formed in the surface of the cylinder (1) over a circumferential portion, onto which ducts (12, 13) are arranged in the rotation atomizing body (9) in each case connect resulting in that a very even cone mantle with a vertical angle of 150.degree. can be achieved so that the atomized liquid strikes the field produce on the underside of the leaves.

  • Patent number: 4700896
    Abstract: A rotary type electrostatic spray painting device comprising a rotary shaft supported by static pressure air bearings in a non-contact state. A drive turbine wheel and a braking turbine wheel are fixed to the rotary shaft. A paint injection nozzle is provided for feeding paint onto a cup shaped inner wall of the spray head. The paint injection nozzle is connected to a paint suction device. When changing the color of the paint, pressurized air is injected towards the braking turbine wheel and, at the same time, paint remaining in the paint injection nozzle is sucked away by the paint suction device.

  • Patent number: 4688662
    Abstract: An energy absorber system utilizing a pair of housings having facing cavities and with a hollow deformable torsion member interconnecting the housings. One portion of the torsion member is received in the cavity of one housing and another portion of the torsion member is received in the cavity of the other housing. The housing cavities have cross-sectional conformations which receive the torsion member in such a manner that relative rotation therebetween is prevented. Rotation of one housing relative to the other deforms the torsion member elastically and/or plastically. Such deformation absorbs the energy of forces tending to rotate the housings.

  • Patent number: 4688667
    Abstract: The chute attachment is attached to a chute on cement truck at a receiving end so that cement might flow through the receiving end to an outlet end having a reduced size compared to the receiving end and into the desired place. A closure assembly is provided to close the chute attachment to thereby cut off the flow of cement, and minimize or avoid any spillage. The chute attachment has a frame which includes a circular assembly having large, middle and small circular members. The members are secured together at a common tangential point and a cover is secured to the frame.

  • Patent number: 4687188
    Abstract: An isolating mount, such as for an engine, comprises a rigid bushing with a resilient rubber block molded around it and cavities formed in the block opening to its exterior on opposite sides of the bushing, preferably located along a plane parallel to the longitudinal axis of the bushing. End plates are bonded to the block surrounding the open ends of the cavities, and these plates may have flanges thereon coated with rubber. Optional floor plates may be incorporated in the block at the bottoms of one or both cavities. Covers are held in sealed relation over the cavities, as by forming the flanges around the covers to retain them. A passage is formed between the cavities, and the cavities and passage are filled with a liquid which is confined therewithin. Displacement of the block in response to forces acting on the mount will result in distortion of the cavities and corresponding displacement of the liquid from one of the cavities to the other to damp motion of the block.

  • Patent number: 4685622
    Abstract: A piece gun for spraying includes a base body. A trunk portion is provided with a storage area for containing a coating liquid. The trunk portion is positioned within the base body. A head portion is connected to the trunk portion. The head portion is provided with a writing member for discharging the coating liquid. A first air passage surrounds at least the head portion of the trunk portion. A second air passage is operatively connected to a source of high pressure fluid. A switching valve includes an operational member for manual actuation and a working member operatively connected to the operational member. The working member initially operates the switching valve to connect the second air passage to the atmosphere during an early stage of operation of the operational member. The working chamber communicates the second air passage with the first air passage during a latter stage of operation.

  • Patent number: 4682734
    Abstract: A spraying device (10) includes a compound fourway rotatable control valve (30), an additive fluid control disc member (84) and a spray selector disc member (104), whereby a primary fluid, such as water, and an additive fluid, such as detergent, can be sprayed or dispensed in various spray patterns separately, or as a mixture having selectively variable concentrations of the additive fluid in the primary fluid. The compound fourway rotatable valve 30 is movable from an inoperative "OFF" position into first, second and third "WATER RINSE", "SOAP-AND-WATER" and "SUDS ONLY" operative positions. The control disc member (84) includes a plurality of orifices (86) of various diameters for controlling the amount of additive fluid dispensed into the primary fluid from a resilient bladder (16) containing the additive fluid as the bladder is collapsed in response to external pressure thereon by the primary fluid.

  • Patent number: 4681263
    Abstract: A low profile sprinkler head has a circular cup-like base with a threaded male coupling for attaching to a buried water supply pipe and an axial bore therethrough. The base includes a plurality of openings to permit sand and debris to fall therethrough. A removable nozzle head is provided for insertion into the bore. The nozzle head includes fluted water passages and various configurations may be provided to produce different water spray patterns. Nozzles are designed to produce a friction fit in the bore. The upper portion of the nozzle head has a curved underside which is disposed within the base to deflect the spray in a horizontal plane. The assembly is installed below the grass mowing level to permit mowing without damage to the sprinkler head.

  • Patent number: 4671392
    Abstract: A vibration damper for vehicles is disclosed with a variable damping force. The vibration damper includes two series-connected damping valve systems which effect a damping force variation by means of a blockable bypass passage. An externally influenceable damping force in at least three stages is obtained in that the bypass passage bridges the two series-connected damping valve systems. This bypass passage has outer passages which open into the chambers separated by the damping valve arrangement and a further intermediate passage which opens to a space between the damping valve systems. At least two passages are closable to change the damping of damping fluid displaced between the chambers.
