Title: Split engine for motor vehicles with divided crankshaft and engine cross shaft for auxiliary unit drives
Inventor: KANIUT SEN HERBERT DIPL ING
IPC: F02B77/14
Filed: 1985-06-27
Abstract: A further reduction of the pollutant emissions is achieved in motor vehicles of all types if the spark ignition or diesel internal combustion engine driving them is divided into a primary internal combustion engine and a secondary internal combustion engine which have their own part crankshafts. The primary internal combustion engine is used conventionally for the drive and it also drives the vehicle auxiliary units by way of a new type of engine cross shaft, whilst the secondary internal combustion engine is automatically started and additionally switched on only for higher performance, but is automatically cut off and stopped again in overrun conditions. The secondary internal combustion engine is switched on and off by a new type of clutch between the part crankshafts, which is controlled by the accelerator pedal without the assistance of the driver and which also produces automatic synchronisation of the crank positions of the two part crankshafts. An additional switch on the dashboard permits additional switching on of the secondary internal combustion engine to be excluded, for example for travelling in motorway queues. The split engine reduces pollutant emissions many times, saves additional fuel and permits cost-effective special engine designs. <IMAGE>

Title: Arrangement for achromatic correction of the extinction error in polarisation microscopes
Inventor: DANZ RAINER DIPL PHYS
IPC: G02B27/28
Filed: 1986-02-28
Abstract: The arrangement according to the invention is used for the achromatic correction of the extinction error in polarisation microscopes. The aim of the invention is to provide an arrangement which provides polychromatic application and guarantees an arrangement of the components which is favourable from the point of view of design and ergonomics. Correction of the extinction error is performed, as known, by the combination of a  lambda /2 retarder, which inverts the rotation of the plane of vibration, and assigned rectifying elements. The object of the invention is to configure the arrangement such that the extinction error is largely corrected for a wide range of visible light, and it is possible for the microscope to have a low design with a spatially favourable arrangement of the polarisation optical operating elements. According to the invention, the object is achieved when at least one glass prism of the Berek type with a refractive index of n=3<1/2> is arranged in the polarisation beam path.
