Abstract: 1,123,054. Telegraphy. SIEMENS A.G. 8 Nov., 1965 [6 Nov., 1964], No. 47217/65. Heading H4P. In a circuit for compensating for D.C. wander in the output of a frequency shift telegraph receiver, the complementary signals A, B from the discriminator DS are converted to a double current signal at d by a pair of potentiometers P1, P2, Fig. 1, which signal passes via a resistor R3 to a variable voltage divider comprising a transistor T whose output feeds bi-stable K. The base voltage is derived from one or the other of two taps, a, b, on potentiometers P1, P2. Depending on the relative magnitudes of the voltage at a, b, and across capacitor C, one or other of diodes G1, G2 conducts, the voltage at a or b then charging capacitor C. The voltage across the capacitor controls the impedance of transistor T such that the double current signal passed to K has no D.C. bias.

An oscillator comprising a valve or transistor having feedback via a frequency-controlling four-terminal piezo-electric filter F 5  is employed as at least one stage of a dynamic bi-stable or monostable circuit. Fig. 3 shows a dynamic bi-stable circuit in which, when the voltage E is greater than a predetermined value, transistor T 5  is conductive and oscillates at a fre. quency determined by a piezo-ceramic filter F 4  The filter F 4  provides phase reversal at its natural frequency. When the voltage E is reduced below a predetermined value, transistor T 5  becomes non-conductive, allowing transistor T 6  to become conductive and oscillate at a second frequency F 5 . A conventional tuned transformer band-pass filter (Fig. 4, not shown), may be interposed between the circuit and output terminals A. In Fig. 2 (not shown), the second filter F 5  is omitted. In Fig. 1 (not shown), filter F 4  is omitted and a capacitor is interposed between the collector of T 5  and base of T 6 . The circuit thus behaves as a dynamic monostable circuit producing a burst of oscillations at frequency F 5  each time the voltage at E is reduced below a predetermined value.

Abstract: 1293983 Battery charging systems McCULLOCH CORP 19 Oct 1970 [20 Oct 1969] 49512/70 Addition to 1219324 Heading H2H A method of, and apparatus for, terminating the rapid charging of a battery including supplying a charging current, discharging the battery for a short time each time a predetermined charging condition is reached, monitoring a characteristic of one or more cells of the battery and terminating the charging process when the monitored characteristic reaches a predetermined value, the characteristic being either the terminal voltage of one or more of the battery cells at a selected time after the discharging step begins or the frequency of the discharge pulses during the charging of the battery. A battery 1 is charged from a charging source 2 by way of control circuitry 3, the control circuitry 3 being arranged to monitor the terminal voltage of the battery such that when the battery voltage reaches a predetermined value, the charging current is disconnected from the battery, by means not shown, and the battery then connected, for a selected short time interval, to a discharge circuit comprising a relay winding W B  by closure of a contact A 2  by a relay in the control circuitry 3. Relay W B  is of the "slow to make" type such that its normally open contact B is closed a certain time after the closure of contact A 2  in the discharge circuit. Thus the terminal voltage of the battery 1 is impressed across a zener diode 30 and a resistor 31 a short time after each time the discharge circuit is completed. When the battery 1 becomes fully charged, its terminal voltage attains a value which, when impressed across the zener diode 30, causes it to break down so producing a signal which is applied to the gate electrode of a thyristor 23. Thyristor 23 then becomes conductive and current flows from the battery 1 through the operating winding 21 of a circuit breaker 20 whereupon the circuit breaker opens to terminate the charging of the battery 1. Unnecessary discharge of the battery is prevented by the opening of contact A 2  when the control circuitry 3 is de-energized by the opening of the breaker 20. If desired the apparatus may be modified so that, after opening of the breaker 20, a trickle charge circuit is established. In other embodiments relay W B  is replaced by a monostable multivibrator or by a resistance-capacitance netnetwork. Furthermore, the charging source may be an A.C. source which charges the battery by way of a thyristor, the apparatus being so arranged that the discharge current of the battery is coupled back to the A.C. source. In yet a further embodiment the termination of the battery charging process is made responsive to the frequency of the discharge intervals.
