  • Patent number: 6451270
    Abstract: The present invention is a brine-maker of a two-tank arrangement specifically designed for efficient removal of salt sludge. The first tank is a salt-hopper into which water flows from the bottom and up through salt to form brine and leaves mineral impurities called sludge on the bottom of the hopper. The brine then overflows through strainers into a brine containment tank. The outside of the salt hopper has bracketing means attached. When the sludge needs to be removed, a lifting device is attached to the bracketing means and the hopper is disconnected from the water supply by a quick-fit coupler and removed to a dumping site where it is turned on its side and the sludge is poured out. The salt hopper is then returned to its position and coupled to the water supply. The salinity level of the brine in the containment tank can be adjusted either by adding fresh water or by running the brine back through the salt in the salt hopper. The brine is stored in the brine containment tank until discharged for use.

  • Patent number: 6401413
    Abstract: An insulated concrete form wall building system wherein a first embodiment includes a pair of spaced apart elongated expanded polystyrene sidewalls, each having opposed inner surfaces that are formed with longitudinally spaced apart vertically oriented ribs that terminate in substantially flat surfaces to abut against one another to serve as a concrete wall form. A second embodiment includes a pair of spaced apart elongated expanded polystyrene sidewalls and divisional members with flat sides which are attached to said sidewalls to serve as a concrete wall form. The ribs define channels for receiving concrete poured therein to form a composite polystyrene and concrete wall structure in the first embodiment and the divisional members serve the same function in the second embodiment.

  • Patent number: 6312139
    Abstract: An apparatus used to deliver light from overhead to stimulate plant growth in a controlled environment. The distance between tops of the plants and the lights can be adjusted to correlate with plant growth by a motorized assembly for raising and lowering a bar suspended from an upper support and upon which are mounted growth lights. Horizontal sway of the bar upon which the growth lights are mounted is minimized by a guiding structure for one end of the bar. When florescent growth lights are used, bulk and heat produced by their ballasts are eliminated by locating all ballasts remotely from the apparatus.

  • Patent number: 6290151
    Abstract: A guidance system for providing a steering control for a swing arm on a center pivot irrigation system is provided through the use of two satellite signal receivers. A first signal receiver is located at the center pivot to provide calculated position information for a comparison with the known position of the center pivot. An error signal is generated and is utilized to adjust position information provided by the second signal receiver to produce an improved position information for the swing arm. Such improved position information is compared to the desired path of travel for the swing arm and a steering signal is generated therefrom, which steering signal controls the steering of the swing arm along its desired path of travel.

  • Patent number: 6179734
    Abstract: A new game is disclosed, involving objectives similar to American baseball but with equipment and rules of play tailored for young children. In this new game, there is a bat and a ball that is hit off a tee. The boundaries on the playing field are defined as a right boundary, which is a visual line between teebase and the base placed in a position similar to that of first base on a regular baseball field and a left boundary, which is a visual line between teebase and a boundary marker placed in a position angled to the left of teebase and selected according to the number and skill level of the players. There is only one base and when a batter hits the ball off the tee, he runs to a base placed on the right boundary. The base includes an air bladder that is connected to a sound generating device to produce a sound when the base is stepped on.

  • Patent number: 6167820
    Abstract: An application device used to deliver anhydrous ammonia gas from the manifold on an applicator to the soil and including an ammonia injector. The ammonia injector consists of a smooth, metallic tube capped on one end by a metallic cap which is a precisely hollowed out metal shaft. The ammonia is applied through bores precision-drilled in the cap. The components of the ammonia injector greatly increase the accuracy with which the anhydrous ammonia can be applied, reduce the pressure at which the ammonia must flow through the injectors resulting in better and more even distribution in the soil, and increase the useful life of the injector.
