Title: Process for exchanging a fluid situated in a closed compartment
Inventor: MENTEL GERD
IPC: C03C27/12
Filed: 1993-07-31
Abstract: In order, by means of a process for exchanging a fluid situated in a closed compartment, to be able to essentially completely fill a compartment simply with a desired fluid, a first orifice is formed in the wall of the compartment, via which an essentially closed elastic casing is arranged on the outside of the wall. The casing is pressurised by charging a pressurised liquid in such a manner that the casing expands into the compartment from the outside of the wall through the first orifice, so that the casing completely fills the compartment, displacing the first fluid situated in the compartment. Subsequently, a second fluid is charged into the compartment on the outside of the casing with simultaneous displacement of the casing from the compartment and the first orifice is then closed.
Patent DE-4326862-A1 (DE)
Title: Electronic clutch management system
Inventor: SCHMITZ HARALD
IPC: F16H59/42
Filed: 1993-08-11
Abstract: The clutch, mounted between the engine and a gearbox, is automatically engaged/disengaged by a setting member controlled by a micro-controller which immediately disengages the clutch when a gear shift lever is operated. Upon engaging a new gear, synchronisation commences during which the gearbox speed is monitored so that if a predetermined speed threshold is exceeded the disengaged clutch is engaged with a predetermined adjustment speed up to its engagement point.The amount of engagement, beyond the initial engagement point is continuously adjusted by altering the ideal clutch stroke. The stroke is continuously calculated by using an algorithm, until the speed does not exceed the predetermined speed threshold.
