Title: Electronic transient regulating means for an electronic fuel injection system for an internal combustion engine
IPC: F02D41/34
Filed: 1974-06-26
Abstract: 1479941 Automatic control of fuel injection SOC DES PROCEDES MODERNES D'INJECTION SOPROMI 26 June 1974 [27 June 1973]  28412/74 Heading G3N An electronic fuel injection control system includes an arrangement for adding a signal to the normal fuel injection pulse control signal to compensate for transient charges in an engine parameter. In the arrangement shown a circuit 2 responds to sudden variations in the output of sensor 1 by changing the logic state of output 2b which causes trigger circuit 3 to output a signal to electronic gate 5. The gate 5 receives signals on input 5c from circuit 7 which are derived from the engine ignition pulses and correspond to the instant of fuel injection in each cycle and outputs a pulse to trigger circuit 8 whenever an input is present at both 5a and 5c. The trigger circuit 8 produces a pulse at output 8b whose duration is controlled by the signal input from sensor 13 and this pulse is added to or subtracted from the normal fuel injection pulse produced by computer 9 in the circuit 10. The arrangement is reset either by the sensor I providing an opposite polarity signal or after a predetermined time calculated by the number of pulses fed back to 2c and used to change the charge on a capacitor.

Title: Improvements relating to measurement of r.f. power
Inventor: DAWSON EDGAR FREDERICK
IPC: G01R21/00
Filed: 1951-12-10
Abstract: 710,378. R.F. power, voltage, measurement. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 27, 1952, [Dec. 10, 1951.] No. 28886/51. Class 37. In apparatus for measuring radio frequency power, a source 1 of power to be measured is coupled through a calibrated variable attenuator 2 to a wave guide section' 9 within which a fluorescent lamp 3 alternately switched on and off by a modulated voltage source 5 is positioned between the power source and a crystal mixer 4 connected to a D.C. measuring circuit 7. Variable attenuators 8 are provided in the waveguide between the lamp and the mixer, and between the mixer and a local oscillator 6. The lamp is rotatable in a horizontal plane parallel to the magnetic vector about a vertical axis at the middle of the waveguide to match it to the waveguide impedance, and when inoperative allows R.F. energy to pass from the power source to the mixer while when operative its positive column strongly absorbs such R.F. energy and radiates R.F. noise energy into the waveguide. Thus the R.F. energy from the source is continuously chopped by the lamp energization and in the alternate intervals the mixer receives pulses of R.F. noise energy, so that if the relative amplitudes of the signals are adjusted by attenuators 2 and 8 until the indication of the mixer measuring circuit is the same when the lamp chopping circuit is disabled as it is when the circuit is operative, it is shown that the lamp output power is twice that of the unknown source. Alternatively the lamp output power is adjusted for minimum fluctuation of the mixer signal at the chopping frequency, when the lamp power will equal the unknown source power. The difference in power output between the known lamp output and that of the power source may be retroactively fed back to stabilize the latter.
