Patent DE-19825146-A1 (DE)
Title: Automotive friction clutch with automatic wear compensation
Inventor: ESTER BARBARA
IPC: F16D13/75
Filed: 1998-06-05
Abstract: The friction clamping effect is boosted by an intensifier (56) which acts at an angle (E) to the rotation axis (A), with the axis of the compensator opening (34,38) inclined in relation to the rotation axis. The intensifier reinforces the pre-tension with which a play indicator (42) clamps via a section (40) onto the clamping seat, supplementary to the pre-tension of a spring. The coil spring pre-tensions the indicator and thrusts between a first support surface and a surface on the seat sector of the indicator with the two surfaces held in parallel. The seating sector passes through an opening (64) in the housing (12), the spring engaging the sector clear of the housing altogether.

Patent DE-19856926-A1 (DE)
Title: Fertiliser spreading method using twin disc spreader
Inventor: VELTEN MICHAEL
IPC: A01C17/00
Filed: 1998-12-10
Abstract: During spreading at the edges of fields the rotation speed of the spreader disc nearest the field boundary is reduced in relation to the adjacent disc, and the point at which fertiliser is dispensed onto the slower disc is shifted outwards, independent of the adjacent disc rotation speed. Fertiliser is spread using two or more variable rotation speed spreader discs (3, 4) that throw fertiliser out in the opposite direction to that travelled by the spreader, such that the areas (15, 16) over which the fertiliser is spread overlap. The size of these areas is varied by altering the distance between adjacent spreader discs, whilst the shapes of these areas can be changed by altering disc rotation speed and shifting the point at which fertiliser is dispensed onto the spreader discs.

Patent DE-19904887-A1 (DE)
Inventor: SCHROEDER JOSEF
IPC: A43B13/14
Filed: 1999-02-06
Abstract: The invention relates to a shoe, especially a shoe for small children with an outsole (1) and an upper part (22) attached thereto. Said outsole (1) is provided with a contraction (5) in the area between the forefoot (2) and the heel (3). Such a shoe does not promote in itself the natural heel-to-toe movement of the foot to a sufficient extent during the process of motion of the foot and during the first few steps of the child. The aim of the invention is to maintain the natural flexibility of the child's foot while at the same time giving sufficient protection to the child's foot during walking. To this end, the outsole (1) is provided with a connecting part (4) in the area of the contraction (5) which connecting part has such a flexibility that the torsion of the forefoot vis-à-vis the heel is impeded as little as possible. In the area (10) of the forefoot (2) of the outsole (1) the shoe is highly flexible with regard to the process of motion of the foot due to a corresponding profile (9).
