Title: "Plough with skim coulter"
Inventor: JOCHUMS DIETRICH
IPC: A01B17/00
Filed: 1993-11-18
Abstract: A plough with a plough frame which bears plough bodies and with tools which are assigned to the plough bodies, in particular skim coulters for working in the ground covering, may advantageously be adjusted in a simple manner with respect to the angle of throw of the skim coulter, and thus set, if all the skim coulters assigned to the plough frame are connected via an actuating device and can thus be adjusted in terms of the angle of throw  alpha  about their own pivot axis. The actuating device may be designed as a hydraulic cylinder or electric motor, as a result of which the handleability of said adjustment device is considerable improved, especially since the setting of the angle of throw can be carried out during travel, as a result of which rapid and specific adaptation is possible in the event of a greater or lesser operating speed and in the event of greater or lesser quantities of ground covering and ground cultivation. <IMAGE>

Title: Bicycle frame with folding rear section
Inventor: ELLSAESER DIETRICH GERHARD
IPC: B62K15/00
Filed: 1994-01-11
Abstract: The bicycle frame can have one folding point (2), or can fold on the shock absorbing members (3,4,5), so than no screw lock is required. To fold up the frame, the rear wheel is first removed. The bolts are then pressed out of the fork lock for the springing. This deactivates the springing. The rear fork (6) can then be folded completely upwards. The frame remains stable. Another version is possible with a split monocoque frame, in which the rear wheel is not removed. When the folding point (2) is released, the entire rear end can be turned first down and then up to minimise the space taken up by the bicycle, without the gear change device having to be fixed to the turning point.

Title: Non-contact measurement of moving bodies
Inventor: KINDERLING ECKART DIPL ING
IPC: G01D5/14
Filed: 1994-02-17
Abstract: The non-contact transfer of measured values from rotating or reciprocating bodies, such as rollers or drums or slides, takes a measured value from a small magnet between two fixed magnets, with the position of the three magnets established at a fixed section of the assembly. They are passed in succession by a magnet field sensor where two counters (21,22) are started on the passage of the first magnet, controlled by a clock generator. The counters are stopped in sequence as the other two magnets pass by. The position of the centre magnet is determined through the ratio of the two counts, which is altered proportionally to the level of the measured value. For detection of forwards and backwards running, a further magnet is used with a different polarity. The measurements are evaluated by digital electronics.
