In order to transmit speech digitally signals are transmitted representing the difference between actual speech samples and predicted speech samples, and the parameters utilized in making the predictions. As described input speech, Fig. 1, is filtered 10, sampled 11 and delayed 12 by 60 samples. The difference # N  is then formed 13 between each sample S N  and a corresponding predicted sample Z N . This difference # N  is then amplified by Q, quantized S<SP>1</SP> N  15 to one of two levels, and transmitted. The quantized difference S<SP>1</SP> N  is amplified by 1/Q, and added 17 to the predicted sample Z N  to produce a reconstructed sample r N  which, together with preceding reconstructed samples, is used 30 to predict the next sample Z N  + 1 The parameters b, k and α utilized in the prediction, and the amplifier gain Q, are also transmitted. All of these parameters are computed 40 every 30 samples (5 msec.) by reference to the preceding 120 samples received direct from the samples 11-delay 12 only being present in order to provide time for this to be done. The Specification contains precise and extensive mathematical information about these parameters and illustrates methods of computing them by block diagrams.

Abstract: 1302195 Mass spectrometers SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 14 Sept 1970 [15 Sept 1969] 45282/69 Heading H1D In a time-of-flight mass spectrometer ions travel from a source 1 to a collector 6 along paths 2, 3, 4, 5 that are partly straight and partly helical, the helical part being brought about by an electrostatic field between two coaxial cylinder electrodes of which one surrounds the other, the straight part 2, 3 or parts of the path entering into and/or starting from the space between the cylinder electrodes at a certain angle with the axis of these electrodes and without a radial component, and the length of a geometrical (and not necessarily orbital) helix about the said axis, which length is defined by the said angle and the length of the cylinder electrodes, being of the same order of magnitude as the straight path length. The combination of straight and helical paths produces time focusing i.e. reduction or elimination of differences in time-of-flight between ions of the same kind having relatively small differences in velocity. The said length of helix may be between 0À25 and 4 times the straight path length but is preferably approximately equal thereto. If, in addition, the helical path comprises two approximately equal parts with opposite senses of rotation, further improvement in time focusing is obtained, since the time-of-flight of an ion is rendered independent of small changes in the orbital radius. The cylinder electrodes are preferably arranged and provided with diaphragms, as described in Specification 1,302,194. An output signal from the collecting detector 6 is passed to an indicating and/or recording instrument 7.

Abstract: 1336008 Detecting the passage of hot bodies DECCA Ltd 22 Nov 1971 [30 Nov 1970] 56678/70 Heading G1A In a detecting system suitable for detecting the presence of moving pieces of hot steel three photo-electric detectors having adjacent, laterally spaced, fields of view are connected to an electric circuit arranged to compare the detected output and to signal when the output of the centre detector exceeds a predetermined fraction of the output of one of the other detectors. Preferably the fraction is one half. In an embodiment, Figs. 1 and 3, three photo-diodes 1, 2, 3 are employed and the associated electrical circuit Fig. 3 provides a signal output only when the object being viewed a moving piece of hot metal is present in the central detection plane 8. The three diodes 1, 2 and 3 are connected to operational amplifiers 11, 12, 13 and the gain of the amplifier 12 is be set at twice the gain of the amplifiers 11 and 13. The output voltages of the amplifiers 11 and 13 are limited by shunts 23, 24, each consisting of a resistor and a Zener diode to ensure that the system works even when amplifiers 11 and 13 are saturated. The outputs of the amplifiers 11 and 13 pass through a switching arrangement  in dependence upon the direction of travel of the objects (in the case of Fig.3 photo-diode 14 receives the radiation first), so that if T is the reference voltage (indicating a threshold level, from voltage source 33 and R(1), R(2), R(3) are the levels of radiation detected by the diodes, the comparators 34-37 produce output signals denoting when respectively R(1)>T, 2R(2)>R(1), 2R(2)<R(3) and R(3)<T. An additional inverter 46 provides in addition to the normal function of the comparator 34 a signal representing the inverse of that function, namely R(1)<T. Two diodes 47 and 48 and a resistor 49 from a first AND circuit which give a "switched" on signal to a memory circuit through a diode 50 if (R(1)>T) AND (2R2)>R(1). Diodes 51 and 52 and resistor 53 form an OR circuit whose output represents (R(3)<T) OR (R(3)>2 R(2) which is fed with the output of inverter 46, (R(1)<T), to an AND circuit comprising diode 54 and 55 and a resistor 56, to provide a "switched off" signal to the memory circuit through a diode 57. The memory circuit consists of the diodes 50 and 57, comparator amplifier 58 resistors 59 and 60 and a feedback resistor 61. The memory serves to store the switch-on signal denoted by a positive signal by providing a continuous positive output, until the switch-off signal is received, whereupon the output of the memory goes negative. The output of the memory circuit is fed to any suitable driver circuit 62 and thence to a relay 63 and an indicating lamp 64. The relay can be used for actuating measuring and counting circuits.
