Abstract: 945,951. Automatic control. CONTINENTAL ELEKTROINDUSTRIE A. G., [trading as CONTINENTAL ELEKTROINDUSTRIE A.G. ASKANIA WERKE]. April 8, 1960 [April 10, 1959 (2)], No. 12577/60. Heading G3R. [Also in Divisions G1 and H4] An apparatus for detecting the deviations of two variables from a given datum comprises an optical arrangement for dividing two light beams each into two component light beams such that the relative luminous fluxes of the beams in each pair of beams are indicative of the deviations. The component beams are modulated so that they can be distinguished from one another and are directed on to a common photo-electric receiver. A first embodiment, Fig. 1, describes apparatus for the alignment of a telescope or the like on an object. Light from a body is split at 13 into two beams of equal intensity and these two beams are split into two component beams by separating edges 14,15, which are perpendicularly disposed so that deviations in two directions at right angles can be detected. The component beams are modulated by rotary shutters 1, 2 which impart different frequencies of modulation to the two pairs of component beams. After modulation the beams all pass to a photo-cell 5 whose output feeds a narrow band amplifier 6. Generators 3, 4 give reference signals of a frequency equal to the modulation frequencies and these signals, together with the output of the photo-cell, feed a control system which controls the alignment of the telescope. A second embodiment, Fig. 3, provides an apparatus for controlling the rates of flow of two pairs of liquids and comprises a photo-electric system for comparing the light transmitted through each pair of liquids, after mixing, with that transmitted through a comparison device. The liquids pass via valves 32-35 to chambers 28, 29. Of four light beams, derived from a common source, two pass through the chambers and are attenuated according to the concentration of the liquids therein, and two pass through the comparison devices 30, 31. The beams are chopped by chopping discs 1,2, and are passes to a photo-cell 5. The output of the cell and signals from generators 3, 4, mounted with the chopping discs, feed a control system which controls the valves 32-35, thereby to vary the concentrations of the four liquids.
