Patent DE-4133014-A1 (DE)
Inventor: ADLER UWE DIPL ING
IPC: B60L50/30
Filed: 1991-10-04
Abstract: A private car or commercial vehicle contains a unit consisting of an internal combustion engine (4) and a generator (6) which powers electric motors (12, 16) coupled to the driving wheels (14, 18) via a power-distribution power electronics system (8). As additional source of energy, an accumulator (22) is provided that can also be coupled by the power distribution system (8) to the electric motors (12, 16). An electronic control unit (20) receives running signals from a driving pedal (27), in particular a position signal and a speed signal ( alpha ,  alpha ). The position signal ( alpha ) of the hand throttle (27) is interpreted as a request for a determined permanent power to be supplied by the internal combustion motor (4). When a higher power is required, for example, the internal combustion motor is speeded up to a new, optimum (i.e. with low fuel consumption) working level, whereas the generator (6) is decoupled totally or partially from the load. In the meantime, the accumulator (22) provides the power required to accelerate the vehicle. The speed signal ( alpha ) determines the amount of acceleration. By means of a selector switch, an operation solely powered by the accumulator may be switched on, at the same time as the internal combustion engine is switched off, if no special sensors are provided for that purpose.

The mixt. contains 1-100 pts. wt., pref. 5-50 (10-40)% (based on solid content) of a hydrophilic plasticiser, pref. glycerin, glycerin esters, glycols and/or polyglycols. The extrusion process is chosen such that the sheet has a water content of 1-40 (5-30), pref. 10-20% immediately after extrusion. The sheet is opt. coloured and pigmented with suitable colouring agents and pigments. The sheet is further formed thermally into three dimensional articles and this final state is maintained by polymerisation after the forming process. USE/ADVANTAGE - Used to form sheets and/or moulded articles that are water resistant, but are also biologically degradable.
