Title: Network reactive power measurement and control system - multiplies voltages corresponding to instantaneous valves of current and voltage
Inventor: KOEPP GUENTER
IPC: H02J3/18
Filed: 1976-06-18
Abstract: A first test voltage is used. It is proportional to the instantaneous current value in the power network under test. There is a second test voltage which is proportional to the corresponding instantaneous network voltage, but which is shifted by 90 deg. The test voltages are determined and they are applied for multiplication to an electronic device which calculates instantaneous value of reactive power in the network. Its output is connected through an evaluation device to switching stages for switching phase shifting capacitors.

Title: Remotely controlled model aircraft - has wind driven generator for servomotors controlling flying surfaces
Inventor: SIGLER HELMUT
IPC: A63H29/22

Title: High accuracy track distance measuring system - has regularly spaced repeaters energised at different frequencies for error correction of locomotive distance measurement
Inventor: FUENTE PEDRO DE LA DR ING
IPC: B61L3/22
Filed: 1976-09-29
Abstract: The track-distance signalling and correction system consists of an inductive cable radiator laid the length of the track with a corresponding receiver and demodulator in the locomotive. At regular intervals along the track are distance markers comprising repeaters or transponders each of which is fed with a different low-frequency signal. The change of frequency at each repeater point is detected by the locomotive and this signal is used for error correction of the existing track-distance measuring system in the locomotive. Since the sequence of different frequencies detected depends on the direction of travel of the locomotive, this parameter also may be determined from this type of system.

Title: Carrier for etched silicon wafer during deposition of supporting zone - has silicon coating produced before etching, with uncoated areas to hold wafer
Inventor: EGELHAAF PETER DIPL PHYS DR
IPC: H01L21/3065
Filed: 1978-09-01
Abstract: Prodn. of a semiconductor involves diffusing a zone of opposite conductivity type into a Si wafer of a certain conductivity type from the upper side and etching away from the under side until the min. thickness for operation is attained, the upper side being protected by an oxide film, and then forming a supporting zone of the same conductivity type as the wafer on the under side. The novel feature is that the carrier used during etching has a Si coating produced on its surface before etching, the areas intended for carrying the Si wafers being uncoated. Uniform etching is attained at a high etching rate and the oxide layer is not exposed at the edge. The wafer size is maintained and excessive growth at the edge is avoided. The carrier need by given only one thick Si coating.

Title: Geothermal energy system using pit in earth - has surface heat exchanger to recover heat from steam evaporated in pit
Inventor: JONSCHER ERWIN
IPC: F01K27/00
Filed: 1979-02-24
Abstract: A deep pit inthe earth contains several vertical tubes from the surface. Fuel falls through one tube to drive a generator by kinetic energy before entering a combustion chamber. Air is blown into the combustion chamber by a fan at the surface through another tube. Water descends a further tube and drives a generator by kinetic energy before passing into the combustion chamber where it is evaporated. The steam rises in a separate tube to a heat exchanger on the surface. The heat is transferred in this to a transport fluid which drops in a smaller tubeto preheat the water before it is evaporated.
