  • Publication number: 20120312888
    Abstract: An improved thin invert composition and method for applying agricultural products to a target area with minimal drift or evaporation is disclosed, based on a water and oil mixture which is emulsified by minimal agitation so as to provide a low viscosity emulsion. The emulsion, when sprayed through small spray orifices (e.g., 0.020 inch internal diameter) forms a thin invert wherein the water phase is enclosed in the oil phase and the droplet size is small (e.g., 1000 microns mean diameter) and uniform. The water phase carries a hydrophilic active agricultural product.

  • Patent number: 5248086
    Abstract: A thin invert composition and method for applying agricultural products to a target area with minimal drift or evaporation is based on a water and oil mixture which is emulsified by minimal agitation so as to provide a low viscosity emulsion. The emulsion, when sprayed through small spray orifices (e.g., 0.020 inch internal diameter) forms a thin invert wherein the water phase is enclosed in the oil phase and the droplet size is small (e.g., 1000 microns mean diameter) and uniform. The water phase carries a hydrophilic active agricultural product. The mixture can have 15 to 50% oil phase by weight, and 50 to 80% water phase by weight, the water phase containing the active hydrophilic product of up to 75% by weight of the water phase. According to the composition and the method disclosed, the surface tension of the droplets formed when spraying is the primary factor determining droplet size, and is kept small and uniform for thorough application to leafy surfaces and the like.

  • Patent number: 4659134
    Abstract: A roll up tarp assembly for a truck having a box with an open top. The assembly includes a tarp support system which is mounted on the open top of the box and a sheet which is located on the support system so that the top of the box is covered. A hollow pipe extending longitudinally across the top of the box is provided such that the hollow pipe is located substantially centrally with respect to the sides of the box. The hollow pipe is placed on top of the sheet and affixed along its length to the sheet. A biasing device is provided within the hollow pipe such that the hollow pipe is urged to rotate towards a a predetermined side of the box and thus roll up the sheet. A locking element couplable to the hollow pipe is provided to restrain the hollow pipe from rotating when the sheet covers the open top of the box.

  • Patent number: 4084908
    Abstract: An improved laser system and method for implosion of a thermonuclear fuel pellet in which that portion of a laser pulse reflected by the target pellet is utilized in the laser system to initiate a succeeding target implosion, and in which the energy stored in the laser system to amplify the initial laser pulse, but not completely absorbed thereby, is used to amplify succeeding laser pulses initiated by target reflection.
