Abstract: 890,833. Binaural systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 9, 1958 [June 19, 1957; July 6, 1957; March 11, 1958], No. 19259/57. Class 40 (4). In a stereophonic sound transmission system of the type described in Specification 871,992, in which there is derived from sounds a control signal representative of the directional significance of the sounds, which signal is used to control the gain of the reproducing amplifiers, the means for deriving the control signal gives emphasis to rising transients in the sounds. As in the above Specification each of the sound signals VL, VR from the left and right microphones, respectively, is applied to an amplifier (not shown), having its gain proportional to frequency so as to emphasise the high-frequency components, the output of which is applied via a phase splitter to a full wave rectifier. Each such rectifier then drives a cathode follower 27 (Fig. 2) which applies the envelope V<SP>1</SP>L (or V<SP>1</SP>R) of the relevant signal VL (or VR) to two differentiating circuits in parallel which produce positive-going pulses from rising transients in the envelope signal, the diodes 31 and 34 removing the negative-going pulses which would otherwise arise from falling transients. The first and second circuits 29, 30 and 32, 33, respectively, produce pulses with time constants of about 10 ms., and 100 ms., respectively. The choice of values of resistors 35, 36 and 37 enables the outputs of these two circuits and the original envelope signal to be combined in the proportions desired to produce the output signal V<SP>11</SP>L (or V<SP>11</SP>R). The two output signals are then applied via further cathode followers to an encoding circuit of the kind described in the above Specification which produces a control signal representing log. V<SP>11</SP>L/(V<SP>11</SP>R+V<SP>11</SP>L). In order to avoid possible distortion the pulses produced by the differentiating circuits may be lengthened whilst substantially preserving their leading edges by the use of a pulse-lengthening circuit. If it is desired to increase the angular spread of the sound images produced the two full wave rectifiers may be coupled by a spreader circuit as described in Specification 890,832.

In a magnetic tape cartridge apparatus a housing 10 contains a light emitting diode (11), Figs. 2 and 6 (not shown), producing via a lens 13 a collimated annular beam 22, 23 enclosing a beam 24 converging to a focus at the plane of the tape 21, which at each desired location, and at least adjacent each end, has two closely spaced apertures 25, 26. When the tape 21, which may be transported by a belt or band around the tape driven by a capstan driven in turn via a friction wheel by a driving wheel, reaches a position at which aperture 25 is aligned with beam 24 and aperture 26 is aligned with a centre one of three photo-detectors 12, light from beam 24 passes through aperture 25 and is collimated by a lens (32) Fig. 3 (not shown), on the face 32 of a prism 30 in the cartridge, to be reflected through 180 degrees inside prism 30 and emerge through a centre one of three further lenses (34) on face 32 as a convergent beam passing via aperture 26 to the centre photo-detector 12. Upper 22 and lower 23 portions of the annular light beam are partially interrupted by edge portions of the tape and are reflected through 180 degrees in prism 30 to emerge via respective said lenses (34) as beams respectively convergent on top and bottom photo-detectors 12. The detector may be powered by a D.C. source or, preferably, a pulsating source thereby giving a pulsed light output. The detection of the upper beam portion 22 is intended to indicate that either the tape has information stored thereon or is blank, and the cartridge may have a manually movable shutter 40, Fig. 4, selectively locatable to allow or block passage of the upper beam portion from the prism to the top photo-detector 12. Detection of the lower beam portion 23 indicates the presence of the cartridge, and detection of the centre beam 24 indicates that a particular position on the tape has been reached. A similar detector assembly may be applied to an open reel tape machine which is also provided with a reflecting means similar to that in the cartridge. A tape cartridge as described above forms the subject matter of Specification 1465580/24, Division B8.
