  • Patent number: 6607146
    Abstract: The invention relates to an apparatus to be mounted on an agricultural sprayer with the purpose of decreasing the drift and improving the deposition, penetration and uniformity of distribution when applying liquids, such as pesticides and liquid plant nutrients, the use of the apparatus and a method of manufacturing a movable part in one piece. The apparatus comprises a movable part (A) on which a sheet (B) and a sprayer (C) are mounted, which movable part (A) is mounted on a boom (D), and is characterized in that the movable part (A) is manufactured in one piece of an elastic material and is stiffened and weakened in sections and in mounting and use has the shape of a parallelogram.

  • Patent number: 6350409
    Abstract: The invention relates to a heat treatment process for disinfection of seeds from pathogens and other undesirable fungi and bacteria, the process being characterized by supply to the seeds non water-borne heat while regulating the treatment time and temperature with regard to the condition and moisture content of the seeds in such a way that the seeds are heated from outside and in, while evaporation of moisture from the surface of the seed, and owing to that, cooling of the same is prevented and no changes in the moisture content occur.

  • Patent number: 4257010
    Abstract: A method and apparatus for delivering energy to an oscillatory system in a signal transmitter to maintain the system in a state of oscillation. A component of the oscillatory system that affects the oscillation frequency is influenced by the magnitude of a measured condition which is to be transmitted by the signal transmitter. The oscillatory state of the system is sensed through a signal path, and energy is delivered to the system through substantially the same signal path, said energy being delivered in the form of pulses at time intervals longer than a whole period of oscillation of the system to maintain the system in a state of oscillation.
