Title: Reception techniques for intelligibility of an audio frequency  signal
IPC: H03G3/34
Filed: 1972-01-03
Abstract: 1386671 Improving intelligibility of speech signals CUNARD STEAM-SHIP CO Ltd 18 Dec 1972 [3 Jan 1972] 49/72 Heading H4R Intelligibility of a speech signal containing interference is improved by selecting and filtering out 11 a narrow section of the signal in which interference is least and deriving a control signal Vc from the mean amplitude of the section to amplitude modulate 1-3 the interference. The interference frequencies are effectively confined to the original speech syllable envelope and are subjectively less disturbing. The incoming speech signal Oi passes to a compressor 1 whose gain is decreased in response to increase in the control signal V c  whose amplitude equals the syllable amplitude. The output is a signal whose speech content is at constant level with the interference components in the same ratio to the speech as in the original waveform. This signal is limited 2 at the speech level and expanded 3 in reciprocal relationship to the compressor also in response to the control signal Vc. The output Oo is the original speech waveform with the leading and trailing edges of syllables slightly distorted and the noise frequencies within the original enelope. The control signal Vc is the amplified 12 output of a 200 Hz bandwidth filter turnable between 300 and 3000 Hz and receiving the input signal Oi after adjustment to a constant level by amplifier 10 gain-controlled by feedback 14. Impulse noises of short duration are detected 15, 16 to inhibit the control signal. The limiter 2 preferably includes a balanced modulator (17, Fig. 3, not shown), limiter, filter and heterodyne demodulator to produce a limited output free of harmonics.  In a refinement (Fig. 4, not shown) the compression and limiting is performed in an infinite compressor (22) controlled by the speech-plusinterference, impulse noise is detected at the input to the circuit to inhibit a gate (35) for the signals Oi and a further a.g.c. precedes the whole circuit. Intersyllabic "white" noise may be removed by a circuit (Fig. 5, not shown) in which the outputs of respective short (30) and long (31) attack time constant paths are compared (32) to inhibit a gate (26) normally passing the control signals Vc.

Title: Improvements relating to internal combustion engines

Filed: 1969-01-02
Abstract: 1,253,864. Valves. ROBERT BOSCH G.m.b.H. 2 Jan., 1969 [3 Jan., 1968; 24 Oct., 1968], No. 178/69. Heading F2V. [Also in Division F1] A throttle valve assembly in an I.C. engine induction pipe comprises a butterfly valve 2, Fig. 5, controlling the intake air, a by-pass in parallel with the butterfly valve and a device regulating the idling speed by acting on the by-pass valve to increase the intake air flow cross-section into the induction pipe as the pressure in the latter increases from a specific value. When the engine speed increases, e.g. due to a decrease in frictional horse power, the intake manifold pressure decreases causing an evacuated diaphragm box 8, Fig. 5, to expand so that a control member 9 approaches a valve seat 3<SP>1</SP> thereby reducing the flow cross-section of the air flow by-passing the butterfly valve 2. Increasing temperatures shift the regulating characteristic towards higher pressures in the intake manifold by means of a temperaturecontrolled expansion bulb 6 acting on the diaphragm box 8. In another embodiment a metal diaphragm (10), Fig. 6 (not shown), is soldered to the reservoir bottom and the enclosed space is filled with a gas which effects the temperature-dependent expansion, the member 9 being fixed directly to the metal diaphragm. The bottom (11) is exposed to the cooling water or engine oil to sense engine temperature. In another embodiment the device comprises a piston (16), Fig. 3 (not shown), which is movable in a housing bore and has one end acted on by ambient air pressure and its other end acted on by intake manifold pressure, the piston controlling the air flow to the intake manifold.

Title: Improvements in or relating to radio telegraph receiving arrangements
IPC: H04L27/08
Filed: 1944-01-05
Abstract: 577,191. Automatic gain control. CREED & CO., Ltd., and MASON, F. P. Jan. 5, 1944, No. 196. Addition to 557,225. [Class 40 (v)] In a telegraph receiver as claimed in the parent Specification, the automatic volume control voltage is dependent upon the average of the voltage across two condensers charged during successive half-waves of received signals and each discharged to an extend dependent upon the amplitude of the half-wave succeeding the half-wave during which it was charged: The Figure shows the last H.F. stage of a telegraph receiver which receives carrier signals at 2 from an aerial or transmission line, and the main output of which passes to recording apparatus. A portion of the output from 1 is fed through transformer 3 having a secondary 5, 6 with earthed centre tap to rectifiers 7, 8, valves 9, 10, condensers 11, 12 and resistance 18 arranged as shown. During alternate half cycles condenser 11 is charged through rectifier 7, valve 9 being cut off by negative bias. During the other half-cycle valve 9. is rendered conductive and condenser 11 is discharged through resistance 18 whose valve is adjusted so that the condenser is substantially discharged in half a cycle. Condenser 12 is charged during the half cycles when condenser 11 is being discharged and vice versa, valves 9, 10 being conductive during alternate half cycles. Thus the average potential across condensers 11, 12 is constant for a fixed amplitude signal and is a measure of the signal strength. This average potential is taken at the junction of two equal resistances 13, 14 and used to control the anode current of a valve 16 and thus provide at the lower end of a cathode resistance 17 a negative potential which varies with signal strength and which is fed by line 4 as an automatic gain control potential for amplifier 1. With this arrangement slow changes of signal strength during marking periods cause condensers 11 and 12 to by charged to a greater or lesser potential during successive half cycles, and the gain of amplifier 1 is altered accordingly. During the short space between successive marks, both valves 9, 10 are cut off and the gain control potential across condensers 11, 12 is held at its adjusted value except for slow leakage through a high resistance 19. At the end of a signal, the charge on condensers 11, 12 slowly leaks through resistance 19 to allow the gain to rise to a predetermined valve, which is below that at which noise potentials would operate the receiving apparatus. If this were not so, a strong signal would set the gain at a low value and prevent reception of a subsequent signal.

The choke tube and casing may have additional fins to form passages through which the mixture passes and the needle valve may be adjusted relatively to the choke tube. A plug 2 secured by nuts 3 has a square portion 6 and carries the nozzle 7, the outlet from which is controlled bv a needle valve 17 carried by a screwed plug 16 in a choke tube 11 which slides over the part 6 and a boss 10 carried by arms 9.

Air enters through passages 19, 13, 14, and mixture leaves by passages 15, those between the upper fins, and past the throttle valve 21. Adjustment of the needle valve relatively to the choke tube is effected by rotating the latter by an arm 18, the plug 16 sliding in a square hole of the boss 10. In the lowest position of the choke tube, the greater part of the air enters at 13, 14 but as the choke tube is raised more air enters between the lowest fins 8, 12 to dilute the mixture. In a modified construction shown in Fig. 4, the choke tube 11 slides over bosses 22, 23 and the plug 16 slides through a square hole in a part 26 which screws into the choke tube and may be rotated to vary the position of the needle valve 17 relative to the choke tube which is prevented from rotating by a lug 24 engaging a slot in a stud 25.
