Title: Improvements relating to Voltage Regulators.
IPC: H02H7/06
Filed: 1967-02-14
Abstract: 1,174,488. Automatic voltage control. ROBERT BOSCH G.m.b.H. Feb.14, 1967 [Feb.15, 1966], No.6952/67. Heading G3R. A voltage regulator for a D.C. generator 10, which may be an alternator with a rectified output, comprises a power transistor 16 which is connected in series with the generator field winding 17 and a resistor 18 across the generator output leads 14, 15; a transistor 28 associated with an output voltage sensing circuit including a potentiometer 35 and a Zener diode 34; a further transistor 25 having its base connected over a circuit including a resistor 22, an N.T.C. resistor 23 and a variable resistor 24 to the junction between resistor 18 and transistor 16, and having its collector/ emitter path connected in series with resistors 36, 37 across the leads 14, 15; and a thyristor 38 which is connected together with a resistor 41 across the leads 14, 15 and which has its control electrode connected to the junction between resistors 36, 37, the junction between the thyristor 38 and resistor 41 being connected over a resistor 39 to the base of transistor 28. In normal operation, transistor 25 is non-conductive and the current in field winding 17 is controlled in known manner by the functioning of transistors 26 and 28 so that the output voltage of the generator is maintained constant at a predetermined value. If, however, the current through transistor 16 should rise to an excessive value the increased voltage drop across resistor 18 will render transistor 25 conductive to fire thyristor 38, whereby a negative potential will be applied to the base of transistor 28 which will conduct to block transistor 16. The power transistor 16 is thus protected against overload conditions which could arise on the occurrence of a fault condition, e.g. a short-circuit, in the field winding 17. The voltage across transistor 25 may be stabilized by a Zener diode Fig.2 (not shown).

Title: Improvements in or relating to frequency discriminating circuits
IPC: H03D3/08
Filed: 1944-04-15
Abstract: 581,085. Frequency and phase modulation; automatic tuning correction. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 15, 1944, No. 6978. Convention date, April 15, 1943. [Class 40 (v)] [Also in Groups XXXV and XXXVI] A dual frequency-discriminating circuit, for use in demodulating frequency or phasemodulated waves and in automatic frequency control, is arranged to give a steep response for small frequency deviations, and a more gradual response for larger deviations. As shown in Fig. 1, an oscillator 54 feeding an aerial 14 is also coupled to the grid circuit 15 of an amplifier 17, the plate circuit of which includes a coil L1 coupled to a centre-tapped tuned circuit L2C. The voltage of coil L1 is fed through condensers to the anodes of rectifiers 21, 23, as also are the voltages at the respective ends of the coil L2, as described in Specifications 489,094 and 575,583. The resultant voltage across the load resistances 45, 47 has the form shown in Fig. 5b plotted against frequency, giving a gradual slope over a wide range. Voltages at opposite ends of the coil L1 are also fed to a crystal discriminator of the kind described in Specification 580,815, giving an output voltage across the load resistances 49, 51 of the form shown in Fig. 5a. The combined output voltage is related to frequency change in the manner shown in Fig. 5c and is applied through a smoothing circuit TC to correct errors in the frequency of the oscillator 54. The system may be used for automatic tuning of a superheterodyne receiver by adjusting the local oscillator frequency, or for frequency control in a F.M. or P.M. transmitter, as described in Specifications 504,766 and 551,890. The discriminator may also be used for receiving F.M. waves, the detected signal being derived across resistances 45, 47 ; or for receiving P.M. waves, the detected signal being derived across resistances 49, 51. Pure carrier may be taken off at the lead CO to a detector in which it is combined with the unfiltered incoming wave, as described in U.S.A. Specifications 2,063,588 and 2,065,565. In modified discriminating circuits (Figs. 2, 3, 4, not shown), the same pair of rectifiers is used both for giving the steep response curve and the more gradual one. Single rectifiers may be employed instead of the balanced pairs described above. U.S.A. Specification 2,229,640 also is referred to.
