DEVICE FOR CENTERING SHIPBOARD MACHINERY Russian patent published in 1995 - IPC

FIELD: shipbuilding. SUBSTANCE: device has radiator, collimator mounted in way of radiation, straight-way sensors, analyzers which are optically connected with radiator and are mechanically connected with motor. Device is provided with processing unit, generator, matching units, amplifiers, demodulators, filters, modulator and distributed photodetectors mounted before analyzers. Each photodetector is connected with processing unit through respective matching unit, amplifier, demodulator and filter; shaper of beginning of reading is connected to processing unit. Each analyzer has opaque zone in form of ring inside which two opaque sectors are located one of which is rectilinear and other is spiral. Opaque zone of analyzer in form of ring and opaque sectors of this zone form rigid plate-like structure. EFFECT: enhanced accuracy and reduced consumption of labour required for centering. 7 dwg
