    Abstract: 1,095,944. Synchronizing devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 20, 1966 [April 23, 1965], No. 17323/66. Heading G4H. To synchronize input pulses at terminal E with clock pulses fed to a tri-stable device D, each input pulse is fed to the second stage of the device D so that on the occurrence of a clock pulse the second stage output is enabled to apply an enabling signal to AND gate G which passes a signal to the first stage when the input pulse terminates. When the next clock pulse occurs the first stage output is enabled to pass a pulse to terminal a and also to the third stage of the device D so that the system is returned to its rest position by the following clock pulse.

    Abstract: A ratio circuit for providing fine ratio control between a measured value and a desired value at a predetermined instant is provided with a comparison counter accumulating a measured value, and a plurality of selection devices each preset to a fractional proportion of the desired value. The presetting devices are driven by a common pulse source, all but the first presetting device coupled to the source via a frequency divider.
