Patent DE-3208181-A1 (DE)
Title: Limit switch columns
Inventor: JAKOB LUDWIG ING GRAD
IPC: H01H19/18
Filed: 1982-03-06
Abstract: The invention is used to replace limit switches which are generally arranged in a linear fashion, and is fitted to a rotating part of the drive. Two or more columns of limit switch cams having different rotation speeds are driven via different step-down transmissions. The cams in each case operate associated limit switches. The step-down ratios of the individual columns are in this case selected such that the slowest column carries out less than one full revolution for the complete movement travel. The step-down to the next slower column is selected such that the switching accuracy is sufficient for the slowest column in order to define a specific revolution of the next slower column. The same applies to all the intermediate columns. The step-down to the fastest column is designed such that its switching accuracy is sufficient for the application. Break and make functions, as in the case of simple switches, are possible by connecting together in each case one switch from the individual columns.

Patent DE-3226962-A1 (DE)
Title: Hull for higher speeds
Inventor: ESSER GERHARD
IPC: B63B1/38
Filed: 1982-07-19
Abstract: To achieve the aerodynamic buoyancy forces previously occurring only in catamaran-like racing boat hulls, which buoyancy forces are produced in the uniform tunnel-like basic structure of the hull, a stronger load-bearing air cushion is built up at the same speed in a hull having two air passages of the same size narrowing towards the stern in the longitudinal direction, and consequently the hull is given greater buoyancy. In addition, hydrofoils fitted at the front and rear underside of the passages increase the propulsion forces even at lower speeds so that, by the interaction of the aerodynamic and hydrodynamic buoyancy forces, substantial propulsion forces are saved without the speed of the hull being reduced.
