  • Patent number: 4610128
    Abstract: A device for conditioning agricultural products, such as fodder, by generating sparks or electrical discharges at electrodes is disclosed. The device comprises at least one group of electrodes, said electrodes of said group being connected in parallel to each other, and an electrical control system connected to at least said one group of electrodes. The electrical control system supplies at any given moment to at least said one group of electrodes the voltage necessary to produce a spark or an electric discharge at at least one of the electrodes.

  • Patent number: 4552079
    Abstract: A machine for planting seeds includes a rotary soil lifting device which lifts broken-up soil, a tamping roller which tamps the remaining broken-up soil, an arrangement for placing seeds onto the upper surface of the tamped layer of the ground, and an arrangement for conveying the soil lifted by the soil lifting device past and upwardly of the tamping roller and for depositing this soil onto the tamped surface and onto the seeds placed thereon as a layer of uniform thickness. A compacting roller may be used to compact the soil of this layer after the formation of the latter, and the machine includes breaking-up tools of the fixed or rotating type mounted at the front region of the machine for breaking up the soil prior to and to a depth sufficient for the performance of the lifting operation by the soil lifting device. The conveying arrangement may include two hoods which together define a passage through which the lifted soil advances upwardly of and beyond the tamping roller.
