Title: Solar power plant inside transparent dome - has vacuum mirror and heat absorber mounted on tower
Inventor: KLEINWAECHTER JUERGEN DIPL PHY
IPC: F24S23/71
Filed: 1979-08-11
Abstract: The installation costs of solar power plants, which concentrate the incident light by means of optical devices, to a high energy density, depend for the large part on the cost of the focussing appts. There are at present, two basic concepts of solar power plants, the small and intermediate output range type and the larger output type, the first having a combined number of smaller optical focussers, and the second, reflecting heliostat mirrors which reflect the incident light to a heat exchanger at the top of a tower. One version consists of a large, pneumatic vacuum mirror situated in the interior of a transparent dome, and with its degree of latitude arranged fixed towards the south. The vacuumised hollow body, over which the circular mirror foil is stretched, consists of a wall and the floor of the dome. The heat exchanger and cavity temp. absorber are mounted on gimbals on a tower and are always in the focus of the primary mirror.

Title: Range finder
Inventor: CHABORSKI HOIKO DIPL ING
IPC: G01S17/36
Filed: 1981-05-21
Abstract: To measure the phase shift of a modulation signal on a light beam, a light path change-over switch alternately connects a reference light beam, passing through a known path length, and the reflection light beam of the target object to a photoreceiver in order to eliminate its influences. Since the two light beams are never available at the same time at the receiver end, it is known to compare the phase angle first of a signal derived from the reference light beam and then of a signal derived from the reflection light beam in each case with the phase angle of a reference signal which is continuously generated inside the device and to determine from the two results of the comparisons the phase shift between the signals of interest. This requires three highly accurate crystal-controlled oscillators. To achieve a simpler but very accurate range finder with good resolution, a circuit arrangement is provided as dynamic memory which, when the reference light beam is present, begins to generate a periodic zero-phase signal which is coupled to the reference signal with respect to phase and still generates this zero-phase signal when instead of the reference light beam, the reflection light beam is received so that the phase shift of a signal derived from the reflection light beam with respect to the zero-phase signal can be measured by a digital phase measuring device with high accuracy and high resolution and from this the range of the target object can be determined. <IMAGE>
