A vehicle mounted oil recovery system uses a conduit to transport oil from an engine lubricating system of the vehicle to a retort system, mounted upon the vehicle. The quartz arc tube has a cylindrical design which promotes a nearly symmetric longitudinal surface temperature profile during operation. The method according to the invention is compatible to the existing tablet manufacturing methods with their high production speeds and compression forces. An execution profiling section is provided for continuously or intermittently providing execution data used for updating the means for memory allocation. Preferably, a light absorbing layer 140 is provided on adhesive layer 130 of the cholesteric liquid crystal layer 110.
