Title: Improvements in or relating to modulated carrier wave communication systems
IPC: H04J1/04
Filed: 1936-04-16
Abstract: 456,270. Multiplex systems. DEKKER, J. M. D., 11, Kortenaerkade, The Hague.-(Assignee of The Netherlands, King- dom of) April 16, 1936, No. 11004. Convention date, April 30, 1935. [Class 40 (iv)] In a multi-channel carrier transmission system, particularly over land line or cable, channels are grouped in pairs, as shown in Fig. 2, using the upper side band for the lower frequency channel of a pair and the lower side band for the upper frequency channel, the channels of a pair being arranged so that the upper modulation frequencies are adjacent and a single band-pass filter may be used. This, whilst providing substantially the same number of channels over a given frequency range as the system with equal spacing shown in Fig. 1, permits wider spacing and reduces the number of filters. At the receiving end, Fig. 3, the pairs are separated by band-pass filters 4 and the two channels of a pair are separated by supplying the original carriers separately to demodulators 7, 8 associated with low-frequency filters 9, 10. In a modification involving two stages of modulation, the pairs are formed by using two auxiliary carriers of the same frequency for each pair, the pairs being spaced along the transmission bend by main carriers having a different frequency for each pair. The band corresponding to any pair may be used for transmitting music.

Title: Master and slave shaft synchronising units
IPC: G05D3/12
Filed: 1963-03-26
Abstract: 971, 848. Indicating electrically. SIEMENS & HALSKE A.G. March 26,1963 [March 28, 1962], No. 11848/63. Heading G1N. In an electrically-operated slave-shaft synchronizing unit in which the receiver rotor winding consists of two parts arranged with respect to one another and to the slave shaft so that balanced voltages of opposite senses are induced in them when the master and slave shaft positions coincide, the parts of the rotor are electrically connected to a differential transformer to act as arms of a bridge circuit resulting at the output winding of the transformer in either a zero voltage when the shaft positions coincide or an error voltage correlated in phase and amplitude to the direction and magnitude of any positional discrepancy of the slave shaft, which error voltage is fed to control the operation of a motor that effects correction of the slave shaft position discrepancies and the voltages induced in the two parts of the slave rotor winding are fed to circuit monitoring devices. As shown in the Figure rotor winding 3 of the transmitter 1 is rotatable with a master shaft 2 and the three phase stator winding of the transmitter is connected to the similarly constructed stator winding 7 of the receiver 6, the rotor winding of which comprises part windings 12a, 12b and is rotatable with slave shaft 11. The two part windings 12a, 12b act as arms of a bridge circuit in association with differential transformer 16, the output winding of which controls the operation of a follow up motor 18 via amplifier 17 and which motor controls via a mechanical transmission system the slave shaft 11. If the positions of the two shafts coincide so that the rotor windings 12a, 12b are in the position shown in the Figure the voltages induced in windings 12a, 12b are of equal magnitude but opposite phase so that no voltage is induced in the output winding 16c and the follow-up motor remains stationary. If a positional discrepancy exists between the master and slave shafts a voltage is produced in the output winding of the transformer 16 and motor 18 controls the position of the slave shaft to obviate the discrepancy. The state of balance between the master and slave shafts is monitored by A.C. relays 19, 20 respectively inserted in the bridge connections from the slip rings 13,15 to transformer 16 and the amplifier output is monitored by relay 21. The relay contacts 19a, 20a, 21a of the relays may be connected in circuit with lamp 22 which is caused to light when all the contacts are closed i.e. when the positions of the two shafts 2, 11 coincide. If contact interference takes place at slip rings 14 or 13 and 15 the relays 19, 20 fail to operate and the lamp 22 is extinguished. In the event of interference or abnormal operation the relays could be used to render inoperative the follow-up control system.
