Title: Automatic phase control system
IPC: H03L7/099
Filed: 1970-04-24
Abstract: 1307593 Automatic phase control ALLENBRADLEY CO 24 April 1970 [13 May 1969] 19915/70 Heading H3A An arrangement for providing two signals locked at a predetermined phase difference comprises two dividers 11, 12 fed from a common source 10, phase detectors 16, 17, 18 for detecting the phase difference with different resolutions, and means 13 for varying the input to divider 11 to adjust the outputs from the two dividers to the required phase difference. If the phase difference differs from the required phase difference sign detector 49 provides a "0" or "1" output, indicative of the sense of the error, which is fed to unit 13 where it adds or inhibits input pulses to divider 11 to reduce the error. When the two signals are at the correct phase to a first degree of resolution the "hold off" output of the coarse detector 16 enables the medium detector 17, which subsequently enables fine detector 18 when the phase difference is correct to a second degree of resolution. When the fine detector 18 detects that the phase difference is correct it provides a "0" output on line 18a which prevents any further change in the number of pulses fed to divider 11, so that both dividers are fed with pulses at frequency f 0 . Unit 13, Fig. 2, comprises a logic circuit which applies to the second stage B2 of divider 11 a signal where: f m  is a pulse train from source 14; B1 is the output from the first divide-by-two stage of divider 11; S is the error sense signal from unit 49. With an input f o .f m  applied to B1, the output from B1 has a pulse rate less than f o /2, and with the S signal at its "0" level this B1 output is the input to B2. With the S signal at its "1" level further pulses at rate f m  are also applied to B2, the combined pulse rate being greater than f o /2. At the correct phase difference the f m  input is inhibited by the "0" signal on line 18a, Fig. 1, and the B2 input is at the intermediate value f o /2. In-phase detectors.-The fine in-phase detector, Fig. 4, comprises at bi-stable circuit FF1 which is set whenever the output C1 from stage DC2 of divider 11 is "1" and the output C2 from stage DC2 of divider 12 is "0" simultaneously. The output from bi-stable FF1 is coupled to a bistable D1 which is periodically triggered by the trailing edge of the C1 signal via differentiator 43. As long as a phase error exists, the Q output from bi-stable FF1 will be a "1" at the sampling instant and bi-stable D1 remains in its "1" state. When the phase error is zero, output Q remains zero and at the next triggering instant of D1 its output also switches to zero. Operation of the D1 bi-stable is inhibited until the medium detector registers zero phase error by connecting the medium detector output to a "hold off" input of D1. The medium and coarse detectors, Fig. 6 (not shown), operate in a similar manner.

Abstract: 1,177,058. Photo-electric measurement of sheet formation. VALMET OY. April 29, 1968 [Oct.31, 1967] , No.20204/68. Heading G1A. Measurement of the cloudiness, i.e. variations in the formation of a travelling paper web, is carried out photo-electrically. Light from lamp 2 is directed through the web to a photo-multiplier 3. The output from the latter is passed to a device 4 which separates the D.C . component in the photomultiplier output from the A.C. component. The D.C. component is passed to control device 6 which regulates the anode voltage of the photomultiplier thereby to maintain the D.C. component constant and render the photo-multiplier output independent of variations in the average opacity of the web. The A.C. component is measured as representing the cloudiness of the paper, since the D.C. component has been held constant. The apparatus also gives an indication of the base weight (mass per unit area) of the paper since this is dependent on the variations in the D.C. component. Since the regulation of the photo-multiplier anode voltage is to render the D.C. component constant, it effectively follows these variations and-measurement of this voltage by meter 7 thus provides an indication of the base weight. Specification 1,129, 536 is referred to.
