Title: Method of positioning a gyro-compass
IPC: G01C19/38
Filed: 1963-10-30
Abstract: 1,009,169. Gyroscopic apparatus. BENDIX CORPORATION. Oct. 30, 1963 [Oct. 31, 1962], No. 42879/63. Headings G1C and GIN. Gyroscopic apparatus utilizes a single gyro functioning as a gyrocompass and as a rate gyro which effectively stabilizes the gyrocompass against the effects of the earth's rotation and movement of the craft in which the apparatus is mounted, the gyro being mounted so that it is first adjusted so that the angle between the output axis of the rate gyro and a line extending vertical to the earth's  surface is equal to the local latitude angle whereupon the spin axis of the gyro rotar is adjusted to bring it parallel to the earth's axis, the gyro housing finally being rotated through 90 degrees to establish an initial north heading for the output axis of the gyro, so that the gyro will subsequently be effective in maintaining the north heading using the rate gyro output signals. The apparatus comprises a rotor 18 supported for rotation in bearings 20, 22 in a rotor case 16 forming a gimbal supported inside the gyro housing 16 on air bearing shafts as 12. The housing 16 is itself supported in a gimbal 42 on shafts 38, 40, the gimbal 42 being carried by a bracket 48 on shafts 44, 46. The bracket is mounted for rotation on a shaft 49 relative to a supporting member 50. In the first setting-up stage referred to the gimbal 42 is adjusted from its initial horizontal position to an angle equal to the local latitude from the horizontal either manually or preferably by use of a servometer 55 controlled by a potentiometer 100 in circuit with a suitable a/c source. The angular position of the shaft 46 is indicated by way of synchros 127, 133 and suitable circuiting to a latitude indicator 146. The bracket 48 is then rotated by way of the shaft 49 either manually or by servomotor 52 to bring the spring axis of the rotar 18 into a position parallel with the earth's axis. The servomotor 52 is controlled by signals derived from an E -type pickoff 28 on the housing 10, a control arm 24 and vane 26 for the pickoff being mounted on the shaft 12. The output of the pickoff 28 is arranged to be zero when the rotar spin axis is parallel to the earth's axis. The housing 10 is finally rotated through 90 degrees by a servomotor 57 undercontrol of a potentiometer 175 to bring the output axis of the rate gyro parallel to that of the earth, so that subsequently the output signals of the gyro will maintain the angle between the gyro spin axis and the logical vertical equal to the complement of the latitude angle. The angular position of the shaft 49 is fed by way of synchros 180, 182 and suitable circuiting to a  directional indicator 190.

Filed: 1967-09-28
Abstract: 1,188,193. Telegraphy. SIEMENS A.G. 28 Sept., 1967 [29 Sept., 1966], No. 44153/67. Heading H4P. Mutilation of idle time and RQ telegraph signals is detected by transmitting these signals three times in succession, the receiver indicating a fault if less than three (or a multiple of three) successive such signals are detected. At the transmitter, when a continuous mark or continuous space (calling or clearing signal) is received from a subscriber a counting circuit causes the subscriber to be inhibited for the duration of three characters and causes three idle # or idle α signals to be transmitted. At the receiver, the received signals pass to a three character store which feeds a printer. A 3- character cyclic counter counts any received idle α or idle # signals. If three successive idle signals are counted no error has occurred. If two are counted it is assumed that an idle signal has been mutilated to form a text character and so the character following the two idle signals is inhibited and a continuous mark sent to the receiver output. If only one idle signal is counted it is assumed that this is a mutilated text character and an error symbol is printed in its place. Received signals are also checked for errors, e.g. by parity check, and errors result in an RQ signal being transmitted thrice.

Abstract: 1528487 Measuring contours of metal strip electrically NIPPON KOKAN KK 28 Oct 1975 [31 Oct 1974] 44421/75 Heading G1N [Also in Division G3] In the measurement of the edge contour of a metal strip using an electromagnetic type of non- contacting distance measuring device the detection coil of the device is maintained at a predetermined lateral position with respect to the edge of the strip. A steel strip 2 whose edge contour is to be monitored moves past a distance detector 1 the head coil 1a of which forms part of a parallel resonant circuit of an oscillator Fig. 3 (not shown) which as described in Specification 1485514 is connected to a Q-multiplier for providing a linear output voltage versus distance d characteristic, the output voltage being obtained from the high frequency component of the detector output by filter 3a. Initially the coil 1a is aligned with the edge of the strip as shown. If then during monitoring the width of the strip changes or starts to zig zag past the head the detector output signal includes a low frequency component dependant upon the distance of the head from the edge of the strip. The low frequency position signal PS is extracted from the detector output by low pass filter 3b and fed to Schmidt triggers 4a, 4b where it is compared with a reference signal V s . If the strip edge moves to the left from the datum position so that the position signal PS is greater than V s . Schmidt trigger 4a operates to energize relay 4c to cause motor control circuit 4h to control motor 4g to rotate feed screw 4a in a manner to move the coil 1a to the left back to the datum position with respect to the strip edge. Similarly if the strip 2 moves to the right and signal PS is less than V s  Schmidt 4b operates, relay 4d is energized and motor 4g rotates to move the coil 1a to the right. Temperature compensation may be achieved by a temperature sensitive resistance element and a capacitor in the resonant circuit which components have complementary impedance-temperature coefficients.
