Title: Improvements in or relating to electrical oscillation generators
IPC: H03K4/16
Filed: 1938-04-13
Abstract: 515,786. Valve generating circuits. WHITE, E. L. C. April 13, 1938, No. 11281. [Class 40 (v)] To stabilize the frequency of a blocking oscillator or multi-vibrator, the load impedance is made so large that in operation the electrode associated with the back coupling swings to substantially cathode potential so that the charge on the condenser is substantially independent of the valve constants. Preferably the discharging resistance of the grid condenser is connected to a bias positive with respect to the cathode which is comparable in magnitude with and derived from the supply potential for operating the generator. A blocking oscillator circuit is indicated in Fig. 1 the leak resistance 12 of the grid condenser 10 being connected to the cathode 2 of valve 1 through resistance 14 and part of resistance 13, the two resistances being connected in series across the generator supply 9. The valve used should be capable of passing high anode current for a quite low anode potential and is preferably a pentode. The output as shewn.is taken from the screen 4 but it could be taken from the anode 6, if the back-coupling condenser winding 7 were connected to the screen 4. A multivibrator circuit in which one discharge resistance 21 is connected according to the invention is indicated in Fig. 3. This circuit generates very short pulses, the time constant of 25, 29 being made small. A circuit in which both valves are pentodes and both resistances 29, 21 are connected to tappings on potentiometers as 22, 23 across battery 24 is also described.

Title: Electrically controlled fuel injection system for an internal  combustion  engine
IPC: F02D41/34
Filed: 1973-03-08
Abstract: 1428171 Electronic fuel injection systems for IC engines ROBERT BOSCH GmbH 8 March 1973 [9 March 1972] 11315/73 Heading G3N [Also in Divisions G4 and H3] In an I.C. engine, electronic fuel injection system, the quantity of fuel injected by at least one electromagnetic injection valve 11 is determined by the volume of intake air, the latter being determined by providing a temperature-dependent resistor 30 in the air intake manifold 25 and maintaining the temperature of resistor 30 constant by a heating current Jh, a voltage dependent upon this current being applied to a squaring circuit 40 whose output voltage, being a linear function of the air intake volume, determines the injection quantity. As shown, the resistor 30 is arranged in a bridge circuit with resistors 33, 34, 35, a regulator R providing the heating current Jh. The voltage Us across resistor 35 is applied to the squaring circuit 40 in which a voltage Uo proportional to the value of the heating current when the engine is inoperative is subtracted from the voltage Us, and the resulting differential voltage Us-Uo is squared. The squared voltage is applied to an integrator 37 to control the charging of a capacitor during each half revolution of the crank-shaft, utilizing a trigger 18 and a bistable circuit 41, the discharge time of the capacitor determining the duration of injection valve opening pulses S. In one embodiment, Figs. 3 and 4 (not shown), the squaring circuit provides constant frequency pulses whose duration and amplitude are determined by the differential voltage Us-Uo, these pulses being applied to an integrator which thus supplies the squared voltage. In a second embodiment, Figs. 5 and 6 (not shown), a sawtooth waveform is provided, both the period and the rate of rise of the sawtooth voltage being determined by the differential voltage Us-Uo. Specifically, the circuit 40 includes a capacitor, which, for a charging period dependent upon the voltage U S -U O , is charged by a current also dependent upon Us-Uo; and which is maintained in the charged state for a short pre-set retention period, and is again recharged after an immediately succeeding pre-set discharge period. A further storage capacitor is provided, the voltage of which is periodically compared, during the retention period, with the voltage of the first capacitor and brought to the same value as the latter. This latter value determines the squared voltage. A further improvement may be achieved by providing a threshold value for the voltage Us-Uo, below which dependence of the squared voltage on the differential voltage is different from that above the threshold value, such dependence being linear, Figs. 7-10 (not shown).

IPC: G10L15/22
Filed: 1966-03-16
Abstract: 1,172,244. Speech recognition. ELECTRIC & MUSICAL INDUSTRIES Ltd. 9 March, 1967 [16 March, 1966], No. 11423/66. Heading G4R. Voice-operated apparatus comprises means for deriving from the voice an input signal including successive cycles of the voicing frequency, and means for testing the input signal for identification including means for sampling the signal at a plurality of instants after a voicing instant and within the cycle following this instant, the testing means being controlled in dependence upon the voicing instants to reduce the dependence of the tests on variations of the voicing frequency. The voice waveform, from microphone 1, after amplification (with automatic gain control) at 2, is passed via delay 4 to analogue-to-digital converter 5 which digitizes 64 successive samples of the waveform amplitude following each voicing instant (detected as a peak in the waveform envelope by timing control 3). The digitized samples are applied, via working stores 6, 7 used alternately, to a multiplier 10 for comparison with standard signals from a fixed store 11. A series of samples corresponds to a sub-phoneme, and each sample is compared with the standard signals corresponding to a correspond " sample " of a standard subphoneme, and in the case of each sub-phoneme from the microphone 1 this is done for a whole library of standard sub-phonemes. For each sub-phoneme from the microphone 1 in turn, the bit products from multiplier 10 relating to a given standard sub-phoneme are added at 12, and if the result exceeds the maximum previous such result relating to the current microphone sub-phoneme, as determined by comparator 14, it replaces the previous maximum in sum store 15 and the identity of the standard sub-phoneme replaces that giving the previous maximum in identity store 18. When all the standard sub-phonemes in the fixed store 11 have been used, the identity in store 18 is transferred to a shift register 19 which is shifted on for every microphone sub-phoneme, or for every third identical output from the identity store 18. A matrix 21 identifies the phoneme from the series of sub-phoneme identities stored in the shift register 19.
