IPC: H04N3/40
Filed: 1972-03-14
Abstract: 1375604 Television DECCA Ltd 14 March 1973 [14 March 1972] 11861/72 Heading H4F Errors in the positioning of the successive frames of an intermittently driven cine film 2 with respect to a television camera (not shown), which errors occur cyclically and comprise a plurality (e.g. eight) of constant errors each associated with a particular position of the film drive mechanism, are compensated by cyclically selecting an appropriate correction signal from a predetermined set of correction signals, e.g. from eight preset potentiometers 17, and supplying them one at a time to a vertical time base control network 6 of the television camera to shift the position of its scanning raster. The cyclically occurring errors are due, for example, to errors in the positioning of each tooth on the sprocket wheel 7, eccentricity of the drive shaft 8, and errors in the geneva star 9 of the drive arrangement 9-12. The appropriate correction signal may be selected in response to the outputs of photo-cells 15 associated with coded sets of holes in a drum 13 which rotates with shaft 8 and contains a lamp, the signals being decoded 16 and used to operate switch 18 to connect the appropriate preset potentiometer 17 to the vertical time base control network 6.

IPC: G01R31/02
Filed: 1925-05-11
Abstract: 256,680. Smith, W. S., and Channon, H. C. May 11, 1925. Inductances, measuring.-The inductance of a portion of a loaded conductor in continuous or discontinuous longitudinal motion, another portion of which is passing through a heat treating furnace or is receiving other treatment in the process of manufacture, is measured by the outof-balance current of an alternating-current bridge, of which the portion to be measured forms one arm. The cable 2 after leaving, for example, an annealing-chamber, passes over metal pulleys 3, 4 to an insulated metal drum 5. The length L<2>, r<2> of the cable between the pulley 3 and the drum 5 forms the fourth arm of a wheatstone bridge comprising ratio arms R<1>, R<2> and a third arm containing an inductance L<1> and resistance r<1>. The indicating instrument is preferably a Sumpner dynamometer 1, of which the terminals A, B, C of the stationary coils and M, C of the moving coil are shown. An alternating voltage of not more than 200 volts is applied across coil A, B, or of not more than 10 volts across coil C. The alternating current is applied to the bridge arms through a limiting resistance R. The values of the inductance and resistance L<1>, r<1> are preferably such that the bridge is balanced if the inductance and resistance of the portion L<2>, r<2> of the cable are of standard value, the dynamometer 1 being calibrated to indicate differences from these values, or the dynamometer may have a scale calibrated to indicate the inductance per unit length of the conductor.
