Abstract: 1295332 Selective signalling COMPAGNIE GENERALE DE GEOPHYSIQUE 27 Feb 1970 [5 March 1969 9 Feb 1970] 9712/70 Heading G4H [Also in Division H4] The outputs of a geophone array are timemultiplexed and applied to a single transmission line for recording at a remote point, the multiplex sampling being controlled by pulses sent along the line. In the embodiment shown, geophones C are coupled to transmission line 1 by respective assemblages A<SP>1</SP> detailed in Fig. 7. Line 1 is terminated by a pulse generator G and remote digital recording unit E. Each geophone output is fed to line 1 via a noise-reduction filter 31, FET gate 32 and impedance matcher 33 With the apparatus in a recording mode, all geophone outputs are scanned within a 2 msec. period by sequential opening of the gates 32, each particular gate being opened in response to recognition by assemblage A<SP>1</SP> of an address code identifying its position along line 1. In this example, generator G produces a pulse train and coincidence circuit 42 opens gate 32 when the number of pulses in the train reaches a number stored in counter 35. Prior to the recording mode, the apparatus operates in an addressing mode during which the counters 35 store different numbers, constituting the address codes, as follows. Recording unit E sends along line 1 a pulse code signifying "start addressing"; this code is recognized by units 68 which open gates 41 to pass clock pulses from high frequency sources 40 to counters 35; the code is also received by generator G which transmits in response an "end addressing" code; the "end addressing" code is recognized by units 39 which then close gates 41; thus gates 41 are open for periods respectively proportional to the line transmission times between generator G and the different assemblages A<SP>1</SP> and hence t he numbers stored at 35 identify the assemblage positions along line 1. In an alternative embodiment (Fig. 3, not shown) which does not have the prior addressing mode, units 35, 38, 39, 40, 41, 42 of assemblage A<SP>1</SP> are replaced by a counter with a pre-wired output decoder arranged to open gate 32 when a pre-determined count of the pulses in the train from generator G is reached. This counter is reset to zero (or to a present count if it is not desired to sample all the geophone outputs) at the beginning of each 2 msec. sampling period in response to recognition by the assemblage of a synch. signal. In a modification of the Fig. 3 embodiment generator G produces 8-bit address codes instead of single pulses, and the counter is replaced by an address decoder. Details of the synch. signal recognition circuit are given (Fig. 4, not shown).

Abstract: 1303631 Frequency synthesis RACAL INSTRUMENTS Ltd 2 March 1970 [1 March 1969] 11029/69 Heading H3A A frequency synthesizer comprises a variable frequency generator 18 producing an output frequency Fo dependent on a control frequency Fr and a variable frequency divider 20, the frequency Fr being varied as a function of the division factor N 1  of divider 20. The synthesizer may comprise a first synthesizing frequency Fp obtained by a phase comparision of a reference frequency F derived from source 31 of Mc/s. with a signal obtained from a controlled oscillator 36 via a variable divider 40 having a division ratio N 2 . The signal Fp is further divided by a variable division factor N 1  to obtain an intermediate signal Fu which is added to a reference frequency Fs at 30 to obtain a second synthesizing frequency Fc which after a fixed division by n/p at 28 becomes the control frequency Fr. The dividers 20 and 38 may be gauged electrically or mechanically. Adjustment of variable division ratios N 1  causes the output frequency to vary in steps of n c/s. and variation of N 2  causes output to vary in steps of p c/s. A fixed divider may follow the variable divider 38. Figs. 2 and 3 (not shown) indicate arrangements for extending the range of output frequencies.
