Title: Two-Way Synchronous Ciphered Link
IPC: H04L9/18
Filed: 1967-05-18
Abstract: 1,174,174. Digital transmission systems. THOMSON-CSF. 18 May, 1967 [3 June, 1966] No. 23099/67. Heading H4P. In a ciphered transmission system for the transmission of digital data between two transceivers, the cipher/decipher unit at one station is controlled by a constant frequency clock and that at the other station (the master) is so controlled on changing from transmission to reception, or vice versa, that the decipher unit at the respective receiver is in phase with the received ciphered data. Thus, if the propagation time is equivalent to t steps of the cipher unit, when the master transmits its cipher unit must lead that at the remote receiver by t steps, and when it is receiving it must lag by t steps. In the embodiment described, the master station has two clocks respectively controlling the cipher/decipher unit during transmission and reception. When the master station is switched from transmission to reception or vice versa, a signal representing the phase difference of the clocks is generated. If the master station has been switched to transmission, the signal is reduced to zero by clock pulses at a rate 2f, f, being the normal stepping rate of the cipher/ decipher unit. The clock pulses required to do this also step the cipher/decipher unit, no ciphering taking place during this stepping, to bring the unit to lead the slave station's unit. When the master station is switched to reception the phase difference signal is reduced to zero by clock pulses at a rate f. During the time required to do this no stepping pulses are fed to the cipher/decipher unit, which is thus brought to the correct lagging phase.

Abstract: 660,136. Cold-rolling. MACCHI, A. Sept. 15, 1948 [July 4, 1947], No. 24237/48. Class 83 (iv). In a device for cold-rolling bars to polygonal cross-section, rolls having cylindrical rim surfaces of a width equal to the polygonal sides and having conical side faces in mutual contact are mounted on radially adjustable bearings and some or all of the rolls are driven by pairs of bevel pinions actuated from a single driving gear mounted on a hollow axle through which the bar passes. In a device for rolling round rod to hexagonal section six rolls 1, 11, Fig. 5, are mounted in radially adjustable carriers 4 on a frame 26 and three of the rolls 1 are driven through bevel gears 7 on each of their side faces by oppositely rotating pinions 6. Each pair of pinions 6 is geared together and one of each pair is directly coupled to one of three flexible telescopic shafts 23, Fig. 7, which are driven from an electric motor 16 through a speedreduction gear-box 24. A central hollow pinion 9 in the gear-box through which the rod passes drives gears 8 on the ends of each shaft 23 and may have teeth of sufficient length to permit the gears 8 to be mounted in different planes. A number of the machines may be arranged in line and in the first stage the rolls may have convex rims in order to improve the corners of the work. The carriers 4 are adjusted by radial screws 13 which are locked by screws 14. The rolls may have ribbed or fluted working faces.

Abstract: 840,968. Amplifying circuits. RICHARD, L. Aug. 10, 1956 [Aug. 10, 1955], No. 24598/56. Class 40(6). [Also in Group XXXVI] In a harmonic analyser (Fig. 6), mains input is applied over a calibrated potentiometer attenuator Sl and switch S4 (allowing the introduction of a calibration check signal) in series with a diagonal of a Wien bridge excluding the fundamental and short-circuitable by switch S3, to a phase splitting valve V1 between whose anode and cathode there is connected a capacitance C and variable resistance R, whose junction supplies a similar phase splitter valve; capacitance and resistance in turn feeding an output valve V3 whose cathode is coupled through a feedback control potentiometer P and a phase reversal valve V4 to the input of V1. The anode of V3 is coupled to cascaded amplifier valves V5, V6, V7 of which the latter is coupled over a series variable resistance R10 to output valve V8 energizing a bridge rectifier operating a pen recorder (E). In operation, the resistances R are ganged for adjustment with R10 and in conjunction with capacitances C each introduce a 90 degree phase shift at a selected frequency determined by the adjustment, at which positive feedback exists over V1 to V4 to produce amplification thereof, while negative feedback attenuates other frequencies; resistance R10 being similarly adjusted to compensate for losses in the Wien bridge at the selected frequency. By adjustment it is thus possible to select successive harmonics of the mains input frequency, whose amplitudes are successively recorded. Plural assemblies of phase shift selecting valve circuits such as V1 to V4 may be arranged in tandem and adjusted by a common control to achieve a band-pass characteristic.
