Title: System for Systematic ground cultivation
Inventor: HILKER ANDREAS
IPC: A01M21/04
Filed: 1996-02-10
Abstract: The system comprises a number and volume of plants, animals, fungi, bacteria and the long term population of these as also of hormones, metabolic substances or toxic agents can be multiplied or reduced directly or indirectly by light, heat, cold or electrons etc as used to synchronise the germination of plants to be eliminated regardless of when the plants etc., reached the ground. The exchange processes in the ground can be controlled by the introduction or removal of agents or processes thus also regulating the plant etc numbers and controlling pests. The agents used for this may influence the ecological balance of the soil organisms and produce an overall exchange balance e.g. net mineralisation rate. Electron beams, infra-red or ultraviolet light are used to influence the phytochromic system of the photo-germinating seeds. The agents can be mechanically protected or composed themselves of pressurised water cutting jets (b) etc so the ground passes near reactors e.g. burners (a) or emitters.

Patent DE-19813301-A1 (DE)
Inventor: SIEGEL HEINZ
IPC: F04B1/04
Filed: 1998-03-26
Abstract: Previously, there were often noise problems with pump units which had a drive motor (2) mounted on a pump block (4). It turned out that these noise problems often originated in the amount of play (41,42) required to mount the drive motor (2) onto the pump block (4). In the inventive pump unit the amount of play (41,42) required to assemble the pump unit correctly is dispensed with by introducing a plastic material. The inventive pump unit is especially designed for anti-slip motor vehicle braking systems.

Title: Method for tunnelling and for lining tunnel walls
Inventor: POTSCH GUENTER
IPC: E21D11/14
Filed: 1998-05-28
Abstract: A method for tunnelling uses tubular elements (3) which are driven through the soil. Each element has external grip strips which interlock with adjacent elements to form the tunnel wall. The grip strips are spaced at less than 180 deg.  to form the curvature of the tunnel. When all the elements have been positioned they are filled with concrete to form a solid load supporting lining. The concrete can be strengthened by reinforcing rods through the tubes and secured at each end of the tunnel via support rings. The interior of the tunnel can then be excavated.
