Abstract: 1337254 Formant tracking vocoder PLESSEY CO Ltd 19 April 1971 [27 Nov 1969] 58067/69 Heading H4R In a formant tracking speech analyser the speech is directed through two parallel paths each of which includes an inverse filter F -1  or F -2  to remove the effect of one formant, and a formant tracker ZC1 or ZC2 which detects the frequency of the other formant. A number of different types of formant tracker are described. The output of the formant tracker of each path is fed back to control the tuning of the inverse filter in the other path. As described the formant tracker may operate by counting zero crossings of the input to the formant tracker SF1 or SF2; or may determine the frequency by an auto-correlation technique using a single delay circuit, Fig. 2a (not shown), or a shift register, Fig. 2b (not shown). Alternatively the formant tracker input SF may be fed to a phase shifter N1, Fig. 3, and the input and output of the phase shifter applied to a phase sensitive rectifier PSR the output from which provides the formant tracker output and also is fed back to control the phase shifter N1. In another alternative formant tracker the formant being tracked is compared, after modulation by a swept frequency oscillator VCO, filtering, and detection, with a formant synthesized by spectrally flattening the input signal and shaping by a filter Fl. The frequency of the filter F1 is controlled by the result of the comparison to follow the formant in the incoming signal, and provide a formant frequency analogue S(f). Another embodiment, Fig. 5, uses a ratio measuring tracker in which the input signal is detected, integrated and passed through a logarithmic converter LC1 to be compared in a differencing circuit S2, with a signal derived from the same input but passed through a shaping network SN, having amplitude frequency characteristic which increases at 12dB/octave, a rectifier R2, integrator I5, multiplier M5 and logarithmic converter LC2. Multiplier M5 is fed with the difference signal S(f), from S2, which also provides the output. Also described, Fig. 6, is a method of determining the amplitude and mark space ratio of the excitation function of the speech using two inverse filters F -11  and F -22  controlled by the respective formant trackers so as to remove the effect of both formants in a signal fed to an amplitude detector AD and a mark space detector MSD. The excitation function frequency is determined by envelope detection and counting the signals at the inputs to the formant trackers FIT and F2T, and selecting the most probable value of excitation frequency by the logic circuit LC1.

Abstract: 1347703 Piercing billets; extruding W J SHARON 23 Feb 1971 5191/71 Headings B3H and B3P In a method of making a tubular metal article 12 providing a die having an open ended bore 16 for circumferentially confining a slug 10, positioning a piercing punch 24 within one end of a die bore 16 and placing a first slug 10 in the other end of the bore, whereupon the slug is forced over the punch to form the tubular article 12. As a punch 26 is advanced, it pushes the lowermost slug 10 out of a shoot 47 into the die bore. This slug abuts a second slug, which forces a third slug over the piercing punch. A circumferential shoulder 85 prevents the second slug being withdrawn with the formed part 12 when the punch 24 is withdrawn from the die. The part 12 abuts a guide 60 for the punch 24 and is stripped therefrom into a shoot 66, Fig. 4 (not shown). The punch 26 has a point 87 which forms an indentation 88 in the ends of the slugs, so that the punch 24 does not carry a thin metal skin into the second slug as it pierces the slug being formed.
