Patent DE-3439710-A1 (DE)
Title: Multi-purpose tool carrier
Inventor: WILDNER BALDUR
IPC: B60K5/08
Filed: 1984-10-30
Abstract: In order to provide agriculture, in particular, with as universal a prime mover as possible, a second engine (the combine harvester engine is preferably used for this) is fitted in or mounted on the existing tool carrier system. By means of an intermediate transmission and suitable operating controls the second engine can be used both in synchronous operation and as separate drive for a second power take-off shaft. This is possible due to the use of the existing power take-off shaft directly driven by the engine. The shaft is designed as road and live power take-off shaft. A new feature of the transmission is that a second power take-off shaft is fitted, which can be driven both by the synchronously connected engines and by the external engine alone. Both power take-off shafts have external connection points and can be used together or separately.

Title: Brake pressure control system for a vehicle
Inventor: SCHRAMM HERBERT
IPC: B60T8/1761
Filed: 1986-11-21
Abstract: A brake pressure control system, especially an antilock control system, with inductive measuring transducers is described. In this system, that speed at which the individual measuring transducer reliably comes in is determined when starting up; this value is stored and in the event of control is used to individually fix the limit speed for each measuring transducer from which the measuring transducer no longer determines the brake pressure control on the associated wheel. From this point in time, the brake pressure is instead fully built up on the wheel or the existing pressure kept constant or control assumed by another measuring transducer. Only when a plurality of measuring transducers have fallen below their limit speed is the control unit as a whole switched off.
