Patent DE-3843141-A1 (DE)
Inventor: DREYER HEINZ DR
IPC: A01C15/04
Filed: 1988-12-22
Abstract: Distributor for the distribution of seeds in particular by means of a dispensing system, from which the seeds being dispensed are supplied uniformly via seed coulters connected to seed lines, the seed supply to individual seed coulters being interruptible. In order to improve the distributor of the relevant generic type in such a way that the same quantity of seeds in relation to the working width of the distributor is always deposited in the ground, the seed supply to individual seed coulters (5') is interrupted by diverting the material dispensed to these seed coulters (5') through coulters (5") adjacent to the "cut-off" seed coulters (5'). <IMAGE>

Patent DE-3908209-A1 (DE)
Title: Ice fender on the bow of ships
Inventor: RADTKE JOACHIM
IPC: B63B1/34
Filed: 1989-03-14
Abstract: To reduce the resistance of ships in slushy ice, oscillatory plates are arranged at the bow of the ship in outer-skin pockets in such a way as to end flush with the outer skin. These plates are excited electromagnetically to induce vibrations perpendicularly to the outer skin. By these vibrations, the slushy ice particles are forced away from the hull and are in turn excited to induce vibrations, as a result of which the friction between them and between them and the ship is reduced. Accumulation of ice at the bow of the ship is prevented and the resistance of the ship is reduced.
