Title: Method for improving target shooting braking from the secondary retarders of a gravity shunting system
Inventor: ENNULAT DIETRICH DIPL ING
IPC: B61L17/02
Filed: 1993-02-16
Abstract: When a descending train section passes through the sorting siding its actual running behaviour changes with respect to the running behaviour predicted during the control of the secondary retarder and the train section frequently reaches its respective target with an excessively high advancing speed. For this reason, for the purpose of establishing the drifting speed of a train section out of a secondary retarder, the invention provides for the value of the running resistance determined for the train section to be modified, specifically by a variable which results from the measurement error due to the method, mass-dependent errors and the expected influence of the sheltering from the wind in the sorting siding on the advancing speed of the train section. Sheltering from the wind occurs preferably as a result of vehicles which have previously entered the adjacent tracks and over which the wind is flowing onto the descending train section.

Title: Centreboard, which can be filled with water, as trimming ballast for sailing yachts
Inventor: ROESLER JOERG
IPC: B63B41/00
Filed: 1993-03-31
Abstract: A yacht which is luffing has a certain angle of heel depending on wind strength, trimming crew, and the keel weight. This has an adverse effect on the speed, and furthermore a trimming crew can only be used to a limited extent. The centreboard is intended to create a windward ballast which reduces the heeling of the sailing yacht, can be used constantly and is independent of the number of crew members, so that a higher speed of the yacht is made possible. In small sailing yachts, one centreboard each is mounted on the port and starboard side; in larger yachts, two or more centreboards each are mounted. Each centreboard is pivotable in all directions and it can be extended and filled gradually with water. The function of the centreboards is based on the principle of a crew trimming on the trapeze. The centreboard is suitable for keel boats, cabin boats, cruisers, yachts and also for catamarans and trimarans for shorter and longer turns.
