Title: A fuel burning system
IPC: F23D11/28
Filed: 1963-11-06
Abstract: 983,686. Burners. COMBUSTION ENGINERING Inc. Nov. 6, 1963 [Nov. 29, 1962], No. 43782/63. Heading F4T. A fuel burning system comprises a plurality of burners each having a fuel supply line 24 and a fuel return line 30 extending from flow and return manifolds 16, 20 and a pressure sensitive device 62 connected across a one-way valve 60 in each return line 30 and arranged to close a valve 40 in the corresponding supply line 24 if the fuel tends to flow in a reverse direction in the return line. The pressure device 62 comprises a diaphragm 64 connected to electrical contacts 68 controlling the valve 40. In normal operation the pressure on one side of the check valve is greater than that on the other and consequently the diaphragm 64 maintains the contacts 68 open. If a rupture occurs in the flexible hoses 44, 46 leading to a burner or excessive wear occurs in the burner tips the back pressure in the return manifold 20 due to the proper operation of the other burners is greater than the return pressure in the line 30 and therefore the diaphragm 64 moves to close the contacts 68 and hence close the valve 40 in the fuel supply line 24. The burner 10 is moved axially by an air piston 48 and comprises (Fig. 2) a central oil supply passage 82 feeding oil through restricted openings 88 into a chamber 84, which is connected by a restricted opening 90 to an oil return passage 80, and an atomizing nozzle 86. The system also comprises a prechecking system to test the oil lines before oil is delivered to the burner 10. The prechecking system comprises a flow measuring device 118 consisting of a diaphragm 119 connected to electrical contacts 122 adapted to close the fuel supply valve 40, connected either side of a restriction 116 in a fuel line 108 connected downstream of the valve 40 and to a three-way valve 112 in the burner return line 30. The restriction 116 is also connected through a one-way valve 115 and a line 113 to a three-way valve 100 connected to a source of steam or air. To test the fuel lines the valve 40 is closed and the line 108 connected by the valve 112 to the oil return line 30 and steam or air is passed through the restriction 116 which registers a given pressure differential; if this differential is exceeded the contacts 122 operate to interlock the valve 40 (i.e. valve 40 has to be manually reset). A restriction could be placed in line 108 or 110 and the pressure difference measured thereacross and used to indicate a break in an oil line.

Title: Apparatus for deriving pitch signals from a speech wave
IPC: G10L25/93
Filed: 1961-12-07
Abstract: 918,941. Vocoders. WESTERN ELECTRIC CO. Inc. Dec. 7, 1961 [Dec. 27, 1960], No. 43803/61. Class 40 (4). In a pitch signal generator and voiced-unvoiced detector the peaks of a signal representing a portion of the speech band are sampled and a unidirectional signal is derived from the largest of the sampled peaks and this signal is compared with the average value of the speech signal to determine whether the speech is voiced or unvoiced and the signal is also used to generate a further signal indicative of the pitch of the speech. Fig. 2 shows a pitch detector in which speech from microphone 10 has its polarity adjusted, via switching circuit 2, so that its maximum peaks are negative joining, this signal is limited to the band 0-300 c.p.s. in filter 201 and applied to the sampling pulse generator 202 and sampler 203. Sampling pulses to apply to sampling circuit 203 are obtained by differentiating and infinitely clipping the band limited speech wave to obtain a rectangular wave the axis crossings of which correspond to peaks in the speech wave. The positive-going axis crossings, corresponding to negative-going peaks, trigger monostable multivibrator 23 to generate the sampling pulses. Pulses from generator 202 control a transistor gate, Fig. 4, not shown, to feed samples of the peaks of the band limited speech to peak rectifier 31; Fig. 3B shows the band limited speech, Fig. 3G the samples at the negative-going peaks and Fig. 3H the output of peak rectifier 31 showing how positive-going samples are eliminated and how spurious pulses such as Vs, of lower amplitude than those derived from the maximum negative peaks are largely ignored if the time constant of the peak rectifier is suitably chosen. The averaged sawtooth wave is compared on the base of transistor 51 with the rectified filtered speech wave. from source 10. Dependent on the relative magnitudes of these signals transistor 51 is switched either on or off resulting in a two level voicedunvoiced signal. The sawtooth wave is also converted into a pulse waveform in generator 204 which is applied together with the voicedunvoiced signal to " and " gate 206 to eliminate spurious pitch pulses from the output during unvoiced sounds. Specification 466,327 is referred to.

Abstract: 1414884 Electro-physical measurements COMMISSARIAT A L'ENERGIE ATOMIQUE 19 Sept 1973 [6 Oct 1972] 43932/73 Heading GIN In the detection of the variations in the crosssection of a tube by means of a cylindrical probe carrying capacitive transducers inserted within the tube, the probe is pneumatically supported so that its axis coincides with that of the tube and a torque is applied to the probe about its axis to align the probe with the major and minor axes of the tube. Probe 1 comprising a casing 4 having an extension 5 which is rotatably mounted in collet 6 of a casing holder carries four capacitive transducers 13 arranged in pairs at opposite ends of two perpendicular diameters respectively, each transducer comprising a central electrode surrounded by a circular guard ring electrode, Fig.2 (not shown) and being connected via leads 19 to a bridge circuit. Duct 10 allows compressed air to be passed to cavity 11, acting as a manifold, and thence via radial ducts 12 to the spacing between casing 4 and tube 2 being tested to form an air cushion whereby the casing 4 floats freely within tube 2 so that the longitudinal axes of the tube and casing coincide. The front end of casing 4 is provided with two recesses 21, 22 connected by lateral duct 23 which co-operate with end cap 24 to form two chambers. End cap 24 is formed with four slots 27, 28, 29 and 30 so that some of the compressed air passing through manifold 11 can escape radially from the recesses 21, 22 and act directly on the walls 3 of tube 2 to generate two opposing torques on the casing 4. In this way the casing 4 is rotated by the torques until the reference plane X, X<SP>1</SP> of the casing coincides with the major axis X 1 , X 1 <SP>1</SP> of the ellipse of the tube 2 cross-section, and reference plane Y, Y<SP>1</SP> with its minor axis. The capacitive transducers 13 thus measure the distances between the casing 4 and tube 2 along the major and minor axes of the latter.
