Title: Receivers for phase comparison radio navigation systems
IPC: H03M1/00
Filed: 1968-01-31
Abstract: Specification describes phase comparison navigation receiver wherein phase discriminator outputs representing by amplitude and sign V Sin a and V Cos a, where [alpha] is the phase angle between two received signals, are converted into a digital representation of a, using a phase locked oscillatory " rotor " circuit (see Specification 873,999), to store a rotating vector have components, at the moment of phase locking, corresponding to said two outputs and a pulse counter which starts operating at said moment of phase locking and stops when said vector reaches a predetermined position, whereby the count is said counter represents a. The rotor circuit 30 comprises a closed 360- degree phase shift loop including two integrators 31 and 31a and an inverter 32. The phase discriminator outputs V 2 = V Cos [alpha] and V 1 = V Sin a are applied at time to via input resistors 60a and 60b, to integrators 31a and 31 respectively when switches 44 and 43 are closed. Decoupled feedback resistors 40, 41 and 40a, 41a are such that the output of each integrator becomes equal to the discriminator output applied to its input. Since each integrator introduces a 90-degree phase shift, the result is a rotating vector V, Fig. 4, in the rotor circuit, having components V 1 and V 2 at the outputs of integrators 31 and 31a at time to. Switch 45 gauged with 43 and 44 sets bi-stable circuit 48 at time to whereby ten stage counter 51 starts to count the output of generator 50 via opened gate 49. When detector 53 determines that the vector V has rotated through angle a (zero output from integrator 31) circuit 48 is reset and the counting operation ceases with a count, transferable to store 52 representing a. If the navigation system is the " Decca Navigator " type (" Decca " is a Registered Trade Mark) the three-phase comparisons between the Master station signals and each of the three slave stations signals will be at respective frequencies of 18f, 24f and 30f, such that equal phase differences in the three phase comparisons will represent different fractions of a zone corresponding to a comparison frequency f. Thus each phase difference must be divided in proportions to the comparison frequency to bring all such modified phase differences to the same scale. Therefore three monostable circuits 54, 55, 56 are provided having respective periods (much less than the period of generator 50), in the proportions 18 : 24 : 30. When that one of the monostable circuits corresponding to the comparison frequency being used is triggered by a clock pulse a switch 39, normally closed and inhibiting the operators of the rotor circuit, is opened, whereby the vector in the rotor circuit rotates for an incremental amount. Thus the vector will turn through angle [alpha] for less clock pulses at the 30f comparison frequency than at the 24f comparison frequency.

Abstract: A transistor amplifying circuit comprises first and second transistors with the base of the second transistor direct coupled to the collector of the first transistor and its emitter coupled to an output terminal by a first resistor which isolates the second transistor emitter electrode from the capacitance of the load into which the circuit operates. A second resistor connects the collector of the first transistor to a source of potential, means for applying signals between emitter and base being provided and including a third resistor for establishing the D.C. potential at the emitter, the ratio between the second and third resistors being such as to reverse bias the collector-base junction of the first transistor by an amount substantially equal to the sum of the forward base to emitter voltage of the second transistor and the voltage developed across the first resistor. Transistors 12, 14, Fig. 1, are connected in long-tailed pair connection and the collector of transistor 14 direct-coupled to the base of a subsequent emitter-follower stage comprising transistor 16 a resistor 28 is connected between the emitter of this and the output load to reduce the effect on the emitter - follower of the capacitance 32 of the output load.. Resistors 20, 24, 28 are so chosen that the static potential of the output terminal is the same as that of the base of transistor 12,. so enabling a number of such stages to be directcoupled in cascade, as in the I.F. amplifier for a frequency-modulation receiver shown in Fig. 3. In the arrangement of Fig. 3, three such stages in cascade are followed by a limiter comprising transistors 362, 364 in long-tailed pair connection, having as common, emitter load the collector to emitter path of a further transistor 366: the base bias of this is derived from a potentiometer comprising resistor 370 and diode 368. The collector of transistor 364 feeds into a discriminator circuit comprising transformer 374 and diodes 382, 384 in conjunction with resistors 386, 388, giving an audio output at terminal 392: a de-emphasis capacitor 390 is provided. Regulated supply voltages are fed to various stages over emitter-followers 414, 416, the supply voltage being regulated by the emitter-base breakdown voltage of transistor 410, the collector electrode of which is left unconnected. A bias supply for amplifier stages 312, 328, 344 is derived from transistors 418, 420 in conjunction with resistors 422, 424, 426: operational stability of stages 312, 328, 344 is obtained by means of overall D.C. feedback over resistor 430, capacitor 432 providing a bypass for A.C. In a modification of the arrangement of Fig. 1, the common emitter impedance comprises the collector to emitter path of a further transistor (Fig. 4, not shown) the base bias of which is derived from a potentiometer network across the supply, the lower arm of which comprises a diode. The arrangements described are suitable for integrated circuit techniques.

Patent ES-427201-A1 (ES)
Title: Audibility-control system for radio receiver
IPC: H04B1/06
Filed: 1974-06-12
Abstract: A radio receiver, especially one installed in a road vehicle, has a first section for picking up special message signals such as road-traffic information and a second section for picking up a normal radio program. A relay energizable by the special signals, normally connected to the first receiver section, automatically switches a loudspeaker from the second receiver section to the first one whenever such signals begin to arrive. A circuit breaker in series with the relay can be manually controlled by a pushbutton, through the intermediary of a bistable storage circuit, to deactivate the relay for shifting back to audible reproduction of the normal program at the will of the user even while the special message signals continue to arrive another actuation of the pushbutton in the presence of these signals restores the original condition. Continuing reception of the special message signals, detected by a sensor connected across the circuit breaker, is visually indicated by a luminous display which is continuously illuminated during reproduction of the signals and which flashes during reproduction of the normal program.
