Title: Improvements in or relating to apparatus for synchronizing a receiver to the transmitter in a time division multiplex signalling system and for converting time position modulated pulse trains into amplitude modulated pulse trains
IPC: H04J3/08
Filed: 1952-06-12
Abstract: 747,393. Automatic frequency and phase control system. TELEFONAKTIEBOLAGET L. M. ERICSSON. June 12, 1952 [June 12, 1951], No. 14883/52. Class 38 (4). [Also in Group XL (c)] In a receiver for time modulated pulses the pulses are applied to the grid of a valve 1 to render conducting a diode 5 in its cathode circuit forming an electronic switch which charges a capacitor 7 to a fixed positive potential + 10 volts, and between pulses the capacitor is discharged through a diode 8 by a constant current circuit 10-14 from a negative potential source 13 so that a negative going saw-tooth wave is produced limited, e.g. to - 15 volts, by a clamping diode 6. Pulses of regular frequency (Fig. 2C) from a generator 20 equal to the mean repetition frequency of the whole pulse train and occurring midway between the pulses when unmodulated (Fig. 2 Ao) then actuate an electronic switch 21 to sample the amplitude of the saw-tooth wave (Fig. 2B) at constant intervals and transfer amplitude modulated pulses to an output 22 for demodulation, at the same time the discharging of the capacitor 7 being interrupted during the pulses by a diode 16 biasing the diode 8 to cut-off. The valve 11 forms a bootstrap circuit linearizing the sawtooth and the tube 10 a D.C. voltage reducer. According to the invention the frequency and phase of the generator 20 are stabilized by employing in the system synchronizing pulses (shown shaded in Fig. 2A) having the same frequency as the pulses of a single channel and time modulated by a modulation frequency which is a submultiple of the repetition frequency of the synchronizing pulses to a time displacement which is the maximum permissible for any signalling channel. The synchronizing pulses then produce amplitude modulated pulses which are necessarily of maximum positive and negative value at the output 22 and are detected by peak sensitive diodes 23, 25 of a pulse amplitude comparing circuit 23-30, and variations in the mean amplitude of the above synchronization signals are used to retroactively control the frequency and phase of the pulse generator 20. The modulation frequency of the synchronizing pulses filtered out at the output 22 may be used for separating particular channels from the multiplex pulse train. Specification 662,956, [Group XL (c)], is referred to.

Abstract: 630,639. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO. (United Shoe Machinery Corporation) Ltd. June 13, 1947, No. 15590. [Class 112] In a thread-tensioning device, particularly for shoe-sewing machines, of the kind in which a member is rotated by the thread against the resistance of braking means, this means comprises a resilient friction element having a plurality of turns round a member coupled to the rotating member ; this arrangement secures more uniform thread tension in spite of variations in the coefficient of friction in the braking-means, since an increased grip on some coils of the friction element will cause slight unwinding of other coils to compensate. Means are provided for moving one end of the friction element to vary the friction during the stitch-forming cycle, and to relieve the friction when the machine stops. The device is described in connection with a chainstitch shoe-inseam sewing machine. Thread-tensioning devices.-The thread, on its way to the auxiliary take-up 10 and take-up 8, passes round a wheel 16 comprising a pair of toothed discs on a spindle 18, the rotation of which is resisted by a round-wire spring 23 coiled round a slightlyenlarged end of the spindle and provided with ends formed as shown to allow yielding : the left-hand end is adjustably secured at 26 to the frame of the machine, and the right-hand end to a link 32. Chain-stitching by barbed needles.-The link 32 is adjustably pivoted to a member 38 adjustably secured to the take-up arm 8, so that the element 23 is tightened round the spindle 18, to increase the thread-tension, while the arm 8 is taking up thread. Stopping-gear.-When the machine stops, an arm 58 is rocked slightly anti-clockwise, as described in Specification 548,344, and a member 48 rigid with this arm engages the left-hand end of the spring 23 to uncoil the spring slightly, and thus relieve the friction on the tension-wheel spindle 18. The arm 58 is held in the tension-releasing position by a latch 62 until the latter is withdrawn by a latch 66 engaging a notch in the hub of the take-up 8 when the machine starts.
