Title: Digital communication systems

Filed: 1971-10-20
Abstract: 1368068 Digital diphase transmission POST OFFICE 19 Oct 1972 [20 Oct 1971] 48817/71 Heading H4P A base band to diphase converter comprises a balanced modulating means arranged to receive an isochronous data signal as one input and a carrier signal of frequency equal and 90 degrees advanced to the data signal at a second input so as to generate a diphase output. At the receiver the carrier signal is recovered and applied to a balanced demodulator also receiving the diphase signal and having the isochronous data signal at its output, the derived carrier phase being automatically corrected if outside limits. Advancing the phase of the carrier is advantageous as less energy appears in the lower sideband i.e. signal level is reduced at low frequencies where line distortion is most severe; conversely more energy appears in the upper sideband where attenuation is greatest. At the transmitter a square wave carrier signal passes through a quarter period delay element 4 into a modulator 2, which may comprise a switching type balanced modulator or as disclosed in copending application No. 21881/73, α-modulo-2-adder, also receiving data signals on terminal 1. The output is passed via an amplifier 7 and low pass filter 8 removing higher frequency components to line 10. At the receiver, input at terminal 11 passes through an amplifier 13 and low pass filter 14 to a full wave rectifier 16 giving a double frequency output through narrow band pass filter 17 which is tuned to pass the second harmonic of the carrier to a variable phase element 18 and frequency halving circuit 19 which is controlled in phase by element 31. The output from this is passed back to demodulator 23 and the resultant passed through low pass filter 24 to a squaring circuit 25 where it is retimed by a delayed carrier input on line 27 to produce the isochronous data signal at terminal 28. The delay element 34 is arranged to put positive going transitions in a centre of each element of the demodulator signal. The recovered carrier may be 180 degrees out of phase and elements 29-31 reset frequency halving circuit 19 if timing is incorrect. It is stated that the arrangement may also be used with multi-level base band signals i.e. quater nary. A line equalizer is not necessary but it may be useful to use a partial equalizer produc ing an attentuation frequency characteristic intermediate between an unequalized and fully equalized line.

Protective films of, e.g., glass or resin 19a to 19d and 19f are applied thereto while conductor 18 is covered with a resistive protection film 19e. Solder paste is applied to the conductors 15a, 15b, 15c, 15h, 15i at the connection points of leads 4a, 7a, 8a, 20a for external components, e.g. capacitor 4, socket 7, transistor 20 which are inserted in corresponding holes of the substrate. Leads 7a, 8a of socket 7 and connection 8 are inserted with solder paste to engage connection points on both faces of the substrate, and the lower surface is then contacted with a flow solder bath whereby leads 4a, 7a, 8a bond to conductor 15b on the lower surface while leads 20a, 7a, 8a bond to conductors 15a, 15c, 15h, 15f on the upper surface; the bonds being shown at 21a to 21f.

A pump driven from a reversible shaft has a selector valve in the outlet actuated by the reversal of the pump to reverse the flow. The radial cylinder pump shown has piston controlled inlet ports 31 connected through filter 33 to chamber 16, and outlet valves 34 communicating with channel 37 and channel 41 in a valve housing 12 having a pressure relief valve 73 Fig. 4 (not shown) opening to chamber 16. Channel 41 is connected through a non-return valve 72 to a port 52 connected in the end positions of a valve 45 to one or other port 48, 51 leading through throttle passages to external connections, the port 48 or 51 not connected to port 52 being connected through passage 59 to the chamber 16 so that movement of the valve 45 from one end position to the other reverses the flow to the external connections. This is achieved in the embodiment shown by a worm 62 keyed to the drive shaft 28 and engaging nut 67 connected to the valve 45. Vanes 68 operate in the liquid in chamber 16 and ensure sufficient drag to cause the nut to run from one end of the worm to the other on reversal of the drive shaft. In a modification Fig. 7 (not shown) the nut is not rotatable relative to the pump housing and engages a worm which is spring biased to a central position. On full movement of the valve the nut disengages from the worm but re-engages on reversal of the shaft.
