  • Patent number: 7143860
    Abstract: The present invention provides a handlebar tilting apparatus having upper and lower pivotally attached brackets, a lever, and appropriate connectors to fasten the brackets and lever to each other in accordance with the present invention. In the embodiment shown and described herein, the brackets each adopt a generally U-shaped configuration with opposing side members and a transition member extending therebetween and integral therewith. The lower bracket is stationary and is attached to the steering column of a vehicle using a handlebar for steering. The upper bracket is attached to the handlebar of the vehicle. The lever is pivotally attached to the upper bracket by a lever pin and supports a latch pin that selectively engages notches disposed in the lower bracket.

  • Patent number: 7141605
    Abstract: A method of treating plant and animal systems and inanimate surfaces for the purposes of controlling plant pests, introducing pesticides and nutrients into plants, mitigating frost damage to plants, increasing crop yields, controlling certain plant diseases, controlling arthropod, bacterial, fungal, mycoplasma, rickettsia, and viral pests of animals and humans, and disinfecting inanimate surfaces. The method utilizes the unique multi-directional dispersion property of the tannate complex of picro ammonium formate and the tannate complex of picro cupric ammonium formate, in aqueous solution, combined with a minor amount of a surfactant sufficient to prevent formation of ammonium picrate, to penetrate plant and animal systems and inanimate surfaces and travelling multidirectionally therein. The method is carried out by introducing a small but effective amount of the tannate complex to the plant or animal system or inanimate surface.

  • Patent number: 7117951
    Abstract: Apparatus for raking and cleaning topsoil of undesired materials has a frame supporting a scoop and a rake or comb of multiple tines on a shaft that is rotatable about the shaft's longitudinal axis. Rotation of the shaft can then be used to raise or lower the rake into a raking or combing engagement with the top soil. The scoop is also rotatably supported to allow it to be activated to accumulate undesirable materials. Hydraulic cylinders or equivalent apparatus are provided to activate alternately the rake or scoop as desired by the operator.

  • Patent number: 6994706
    Abstract: An apparatus and a method for treatment of benign prostatic hyperplasia are disclosed. The apparatus includes an applicator piece carrying a set of electrodes shaped and positioned to create a substantial electric field in the volume of hyperplasia and a pulse generator adapted for delivery of electrical pulses above the upper electroporation limit for the neoplastic cells. The amplitude, duration and number of the electrical pulses are generally selected to cause necrosis of a significant fraction of the volume of benign prostatic hyperplasia. The apparatus may include a high frequency system for heating the prostatic tissue and a cooling system for cooling the urethra. The combined action of heating and cooling may increase the temperature of the prostate cells to 45° C. to 55° C., while keeping the urinary tract at a temperature 15° C. to 20° C.

  • Patent number: 6913086
    Abstract: Apparatus and method for shearing a soil layer and removing it is provided. An apparatus in accord with the present invention has a frame mounting a shearing blade reciprocally movable substantially vertically into an operational position where the shearing blade will extend below the ground surface to shear the layer of soil above the shearing blade from the soil beneath it. An apparatus will also have a pushing blade mounted for use in pushing sheared soil. In a method in accord with the present invention, apparatus is provided that includes a shearing blade and a pushing blade. Each of the blades is positionable in operational and non-operational positions. The pushing blade is placed in its non-operational position and the shearing blade is placed in the operational position and is used to shear an upper layer of soil to a desired depth to produce a sheared soil layer and to create a new surface layer below the sheared soil layer.
