Patent DE-4330228-A1 (DE)
Title: Method and device for compressing a gaseous medium
Inventor: WENZEL HARALD DIPL ING
IPC: F03B13/00
Filed: 1993-09-01
Abstract: The invention relates to a method for compressing a gaseous medium, in which the lubricant contained in the compressed medium and serving to cool and lubricate a liquid-injected compressor is firstly separated and then, by using a pressure gradient set between the separating and injecting parts, is fed again to the compressor and the excess pressure is reduced. In order to minimise the loss which attends the reduction in the excess pressure, it is proposed according to the invention that the excess energy is fed to a machine doing mechanical work. A compressor system for carrying out the method is characterised according to the invention in that a hydraulic turbine (30) is arranged in a line (17, 18) which serves to return the cooling or lubricating liquid. <IMAGE>

IPC: H04N1/60
Filed: 1994-11-04
Abstract: The digitiser uses a coloured copy produced using a computer system and a colour printer working in conjunction with the measuring system. The colours of the coloured original are reproduced as faithful as possible on the coloured copy. The measuring system includes a white light source or three coloured light sources (red, green and blue) for the illumination of the original, and a beam receiver system with a linear, charge coupled light electric converter (CCD-lines), for determining the measurement light, emanating from the individual scanning regions of the coloured original. The photo-electrical measuring system in addition has a course-interference filter as a dispersive optical unit, for the splitting up of the measurement light, emanating from the scanning region of the coloured original. This course-interference filter is only then located in the beam course between the original and the beam receiving system, if the coloured original is treated at control panels, the colours of which should be determined colour metrically.
