Title: Device for detecting the overheating of a catalyst traversed by the exhaust gas of an internal combustion engine
IPC: F01N13/04
Filed: 1974-02-28
Abstract: 1461804 Preventing overheating of exhaust gas conversion catalyst; treating exhaust gases ALFA ROMEO SpA 28 Feb 1974 [28 Feb 1973] 9200/74 Headings B1F and B1W An exhaust system for an I.C. engine for a motor vehicle comprises at least one catalytic silencer for the post combustion of the engine exhaust gas and a device for detecting excessive overheating of the silencer catalyst, the device comprising first and second cells disposed in series and traversed by the exhaust gas, the cells containing solid but not compact materials which are traversable by the gas, the material contained in the first cell being a chemically inert material which causes a first gas pressure drop and the material contained in the second cell being a catalytic material which causes a second gas pressure drop, the devicealso comprising means sensitive to the pressure drops undergone by the gas in traversing the cells, a signal being supplied by the sensitive means when overheating of the second cell causes the pressure drop undergone by the gas in traversing the cells, a signal being supplied by the sensitive means when overheating of the second cell causes the pressure drop under gone by the gas in traversing the second cell to exceed by a predetermined amount the pressure drop undergone by the gas in traversing the first cell. Thus an increase in uncombusted components in I.C. engine exhaust gases is detected by cell 26, Fig. 2, due to increase pressure drop across catalyst 25 compared with the pressure drop across inert material 24 caused by the increase in temperature of the catalyst 25 due to increased reaction in the catalyst, the increase pressure drop causing rod 41 to move upwardly to open valve 18, Fig. 1, to allow the exhaust gases to exit via 15 and thus bypass catalytic silencer 21 to avoid overheating catalyst 22. In the embodiment of Fig. 3 (not shown), the catalyst 25 forms the main catalyst of the silencer itself, the inert material being present upstream in the silencer.

Title: Circuit arrangements for correcting television signals
IPC: H04N5/208
Filed: 1967-02-27
Abstract: 1,140,624. Television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 27 Feb., 1967 [2 March, 1966], No. 9202/67. Heading H4F. When a television signal V, Fig. 1 is fed into and then read out of a magnetic recording or like device 2, the signal is found to have had its low frequencies much attenuated and its D.C. level removed. Such an alteration of the television signal V may be understood by giving device 2 a transfer function W, such that the altered output at 4 is VW. In a prior art arrangement, to recover the original signal V, the signal VW is fed to a low frequency amplifier 5, having the transfer function   1/W , such that its output may be represented as   V*, i.e. corrected for the low frequency attenuation, but still without any D.C. level. The D.C. level is thus replaced in a clamp 6 controlled by clamping pulses, frequency fc, having unity transfer function for video frequencies, whereby the original signal V is recovered at the output 8. A low frequency noise signal S (frequency fs << line frequeney fc), Figs. 2a, 2b, appearing at the output of device 2, become S/W at the output of amplifier 5. Since fs << fc, clamp 6 acts on the noise to produce the output shown in Fig. 2b. The clamp 6 with respect to the noise, thus has a transfer function Signal S/W at the input of the clamp 6 thus becomes Sα/W at the output thereof. The signal   to noise ratio at the output, is thus VW/Sα. At low frequencies however (i.e. frequencies of S) W is << 1, such that the low frequency signal to noise ratio is very poor. In one embodiment of the invention Fig. 3, the output television signal V 0 , is fed through a positive feedback network 11 having a transfer function (1-W) to produce a signal V 0 (1-W). This is combined in adder 10 with the output VW of device 2, to produce a signal VW+V 0  (1-W) of the input to clamp 6. Since clamp 6 has no effect on the video frequencies, then V 0  = VW + V 0 (1-W), or V 0  = V. Thus the original television signal is recovered. The noise output S 0  becomes S 0 (1-W) at the output of network 11 and is combined in adder 10 with the noise signal S, to give S + S 0 (1-W) at the input to clamp 6. Clamp 6 operates on the input noise to produce Thus Since for S, however, W<<1 S 0  #αS. The new signal to noise ratio is V/Sα , an improvement by a large factor 1/W at low frequencies over the prior art. An additional low frequency amplifier stage 12, Fig. 4 (not shown), may be added having a transfer function W<SP>1</SP>, whence the transfer function of network 11 ideally becomes (1- WW<SP>1</SP>) or in practice (1-W<SP>1</SP>). If the transfer function of network 11 becomes (1-W/A) then the output signal to noise ratio becomes AV/Sα. A transistorized embodiment of Fig. 3 is given, Fig. 7 (not shown).

IPC: G11C19/18
Filed: 1958-03-25
Abstract: 883,757. Digital data-storage apparatus. ROE & CO. Ltd., A. V. March 20, 1959 [March 25, 1958; June 5, 1958], Nos. 9511/58 and 17971/58. Class 106 (1). [Also in Group XL (c)] A digital data-storage unit comprises a capacitor which is charged or maintained charged at regular intervals and means for discharging the capacitor between said regular intervals. Capacitor c charges fully during the negative part of an A.C. waveform and normally, i.e. while storing the digit O, remains almost completely charged because of rectifier w during the positive part of the waveform. If, however, the digit 1 is entered by discharge of c during the positive half-cycle then c recharges during the succeeding negative half-cycle so causing transistor t to conduct and discharging capacitor c<SP>1</SP> in an associated unit which is fed with A.C. of opposite phase. The stored digit may be stepped round a closed ring in this manner. The base of the transistor may be connected through a rectifier to earth. Two units may be combined to form an OR-gate, Fig. 5, or an AND-gate, Fig: 6. Two units can also be crosscoupled, Fig. 7, so that both transistors are cut off when the circuit stores O and the transistors assume conducting state alternately when the circuit stores 1. This oscillation is maintained by a stream of pulses applied to terminal m, the stream being interrupted when the circuit is to be cleared.

Title: Improvements in electrical transmission of power
IPC: H02J3/24
Filed: 1935-03-29
Abstract: 459,121. Transmission line arrangements. TAYLOR, A. M., 53, Harborne Park Road, Birmingham. March 29, 1935, Nos. 9755, 17340, and 25409. [Class 38 (iv)] In a power transmission system in which quadrature boosters situated at intervals along the line are employed for compensating for the inductance of the line, the lagging current demanded by the booster primaries is balanced by the leading capacity current of the line. In the form shown in Fig. 1, quadrature boosters 5, 6 are arranged at intervals along the line and inject quadrature voltage to correct for inductive drop in the line. The arrangement is designed so that the capacity current of the line balances the lagging booster current. To maintain balance of booster and capacity current at various loads, the supply transformer 1 may be tapped, and the voltage reduced as load current reduces. To maintain voltage at the distant end at normal value, sufficient uncompensated capacity current is allowed to flow on the line to produce an in-phase voltage drop in the line to boost the voltage to the correct value. In a modification, the boosters are arranged so that the booster current is compensated by the capacity current of a section extending on either side of the booster, so that, in addition, capacity current drop on one side of the booster compensates the inductive current drop on the other side. A booster may also be provided at a substation for injecting a quadrature boost from the H.T. circuit into the L.T. circuit. In a further modification, in addition to the quadrature boosters along the line, an inverted quadrature booster is used, the voltage of which is varied in dependence on load so as to vary the amount of effective quadrature boost in the line with load. In a further modification, emergency quadrature boosters are provided which are capable of being automatically thrown into circuit under emergency conditions. Specificaticn 427,721 is referred to.

Title: Improvements in or relating to apparatus for effecting amplitude compression and expansion of electric signals and signalling systems including such apparatus
IPC: H04B1/64
Filed: 1950-04-20
Abstract: 702,045. Automatic volume control. GENERAL ELECTRIC CO., Ltd., and STENNING, L. C. April 18, 1951 [April 20, 1950], No. 9801/50.. Class 40 (4) A volume compressor or expander comprises an amplifier whose gain is controlled in accord-' ance with a bias voltage which is the difference between a control voltage and a voltage obtained by rectifying the signal obtained by passing a signal from a constant amplitude oscillator through the amplifier. The frequency of this oscillator is preferably outside the range of frequencies of the communication signals passed through the amplifier. If it is arranged that the amplitude of the oscillation is great compared with the reciprocal of the rate of change of gain of the amplifier with respect to the applied bias, then the degree of compression or expansion will be substantially independent of the gain-bias characteristic of the amplifier. As shown in the transmitter, Fig. 1, the signal is fed, together with the output from a supersonic oscillator 2, to a variable gain amplifier 1, the supersonic output of which is rectified and the difference between the rectified oscillation and a variable delay voltage is utilized to vary the gain of the compressor amplifier. The variable delay voltage is derived from a smoothing circuit 7 fed by pulses from a gating unit 8 which passes pulses, to the circuit 7 in accordance with the difference between the output level of the smoothing circuit and the mean level of the signal output from the variable gain amplifier 1. The mean level may be obtained by combining a rectified output of the signal with the output from a differentiating circuit which helps to provide a more effective response to sudden changes in level. The signal output is passed to a coding circuit which converts it into pulse code signals for transmission. The compression information is transmitted by adding an additional pulse position to those of the signal code pulses, four successive such positions being used to convey one quantum of compression information. At the receiver, Fig. 2, the received compression information is used to gate pulses to a smoothing circuit 14 which modulates the output of a supersonic oscillator 12, the output then passing through the variable gain expander amplifier 11 whose gain is controlled by the difference between its rectified supersonic output and a fixed delay voltage. In a modification, Figs. 4 and 5 (not shown) the compression information is conveyed by an infrequent periodic substitution of the compression indicating signal for the communication signal. In another modification, Fig. 3 (not shown), the compression is effected by a variable amplifier in the signal path and the expansion is effected by an identical ampliner in the negative feed-back path of a further amplifier in the signal path ; or vice versa.

Filed: 1921-04-04
Abstract: 168,848. Metallurgique Electrique. Sept. 6, 1920, [Convention date]. Automatic circuit-breakers.-A rapidly-acting overload circuit-breaker comprises a fixed bridging contact and two oppositely-movable contactmembers connected with the main circuit and arranged on either side of the fixed contact; one of the contact-members is tripped electromagnetically at a certain overload, and moves rapidly away from tht fixed contact, thereby introducing a resistance and a second tripping magnet into the main circuit which, if the overload persists, acts in conjunction with the first tripping magnet to move the second contact arm away from the fixed contact and break the circuit. As shown, the light rapidly-moving contact-member 7 is held in engagement with the fixed contact 6 against the action of the dead-centre springs 9, 10 which act as shock-absorbers, by the engagement of a lever 13 with the pawl 11, the lever 13 being controlled in unstable equilibrium by an angularly-disposed spring 16, 17 predominating over the springs 9, 10. The lever 13 is linked to a lever 19, 21 which carries the armature 3 of the magnet 2. When the overload arises, the first movement of the armature trips the lever 13 and by separating the contacts 6, 7 introduces the resistance 23 and the second tripping magnet 24 into the main circuit. The armature 3, after tripping the contact member 7, continues its movement and, acting through the link 21, 27 and the floating link 27, 29, tends to move the contact lever 5 to the open position. This movement is assisted by the magnet 24 which lifts the detent 33 and releases the lower end of the floating link. Under the action of the spring 32 the contact lever is rapidly drawn to the off position. It is re-set by means of the handle 31, and the contact-member 7 is re-set by hand or electromagnetically, the handle 31 being used to complete the circuit of the closing magnets.
