Abstract: 814,519. Alternators. JACK & HEINTZ Inc. Nov. 22, 1957 [Dec. 3, 1956], No. 36459/57. Class 35.  To avoid the use of an interphase transformer between the star points of a double-star exciting winding rotating, together with rectifiers, on the alternator pole-wheel shaft, the star-points 16, 19 are connected respectively to one end of series-connected north pole windings 12 and one end of series-connected south pole windings 13 of the pole - wheel, the other ends of these windings being connected to a common point 21 connected through rectifiers 22 to the free ends of the star windings 15, 18. By this arrangement, circulating currents and D.C. voltage unbalance between the star connected windings does not alter the ampere turns per pair of poles because current flowing from 16 to 19 will increase the excitation of one set of poles as much as it decreases the other. The windings 15, 18 are, of course, excited by a stationary pole structure.

Title: Improvements relating to Oscillators particularly for Superheterodyne Radio Receivers
Inventor: HAYNES GORDON
IPC: H03L7/20
Filed: 1967-08-11
Abstract: 1,181,705. Automatic frequency control; superheterodyne receivers. G. HAYNES. 7 Nov., 1968 [11 Aug., 1967], No. 36926/67. Headings H3A and H3Q. The invention relates to an oscillator circuit comprising a main oscillator 13 having a coarse adjustment over a relatively wide frequency range, and automatic fine frequency control for locking the frequency on to one or other of a number of specific values when approximately set thereto by the coarse adjustment. It includes means, conveniently a harmonic generator 22 for generating a spectrum of signals at controlled frequencies, a synchronizing mixer 20 for compounding a signal selected from the spectrum with the output from the main oscillator 13 to obtain a synchronizing intermediate frequency signal, a phase comparator 25 for comparing the latter signal with a signal at a controlled reference frequency and obtaining an error signal, and fine adjusting means 28 to adjust the frequency of the main oscillator 13 to keep the synchronizing intermediate frequency signal in step with the reference signal. According to the invention the reference frequency is so chosen that the minimum frequency of the spectrum utilized is substantially above the maximum working frequency of the main oscillator 13. Preferably the synchronizing intermediate frequency is substantially more than double the maximum frequency of the main local oscillator, being the sum of the frequency of the selected spectrum signal and the output of the main oscillator 13, in order to keep the synchronizing frequency outside the range of second harmonics produced by the main oscillator 13. The arrangement is more particularly intended for a superheterodyne receiver, employing a double frequency change, the oscillator 13 supplying local oscillations to a first mixer 12. The first I.F. amplifier 14 is followed by a second mixer 15 to which local oscillations are applied from interpolation oscillator 16 which is tunable over a range equal to one locked step of the first oscillator 13. Preferably means is provided for switching off the fine frequency control of the first oscillator 13, so that varying its frequency effects continuous coarse tuning adjustment so as to scan the range, the fine control being switched in when a signal of interest has been intercepted. The arrangement permits of using a fixed low-pass filter 21 after the main oscillator 13 and a fixed high-pass filter 23 after the harmonic generator 22. The controlled reference frequency is obtained from harmonic generator 22 by means of multiplier and selector circuits 26. The main oscillator 13 may have two or more switch-selected frequency ranges, each not more than two to one, the spectrum signal being selected by a switched spectrum filter which in any position is narrow enough to ensure that the second harmonic of the main oscillator output cannot beat with a spectrum signal.

Abstract: 1,235,921. Battery charging systems. SAVAGE TRANSFORMERS Ltd. 27 March, 1969 [31 Jan., 1968; 5 Aug., 1968], Nos. 4990/68 and 37188/68. Heading H2H. A system for charging either six-volt or twelve-volt batteries includes a device which automatically switches the system into its sixvolt charging state if the charging current exceeds a preset value. In the embodiment of Fig. 1, the system is shown in its initial state in which it will supply a voltage suitable for charging a twelve-volt battery connected to terminals 7 and 8. In this condition, current flows to the battery by way of an input transformer 3, a bimetallic switch 11 and a rectifier bridge 6. If, instead of a twelve-volt battery, a six-volt battery is connected at terminals 7, 8, the charging current will be much higher and will be sufficient to open the switch 11, so introducing an inductor 14 into the circuit and dropping the output voltage to a suitable level. The inductor itself generates sufficient heat to hold the switch 11 open. Further bimetallic switches 9, 10 and 12 are provided as safety cut-outs, and an indicator lamp 18 shows when charging is proceeding. In a modification, Fig. 3 (not shown), the switch 11 is indirectly heated by an adjacent resistor, and in alternative embodiments the reduced output may be obtained by switching to half-wave rectification from full wave rectification or by changing to a mid-point tapping on the secondary of the input transformer 3.

Abstract: 1520947 Controlling energy-test machines KEIPER TRAININGSYSTEME GmbH & CO 8 Sept 1976 [11 Sept 1975] 37207/76 Heading G3N An energy-test machine comprises a permanent magnet D.C. generator driven via pedals by the person under test, the desired energy to be applied to the pedals being set by a keyboard into the control circuit 10 which compensates for different pedalling speeds by adjusting the load current passed by a load adjusting circuit 8 to such a value that the combined energy of the electrical load and the friction losses in the drive and cooling fan is maintained at the pre-set value. The frictional losses are proportional to speed and the fan loss is proportional to the square of the speed. The generator voltage U is proportional to the generator speed n, and is used in the circuit 10 as an analog of the speed. In block 11 the input total energy value Na is divided by the voltage to derive a required current value. The voltage is also supplied to block 12 where it is multiplied by a constant to obtain the value k 2 n representing the loss in the fan. This is added at 13 to a constant value k, representing the friction loss. The sum is subtracted from the current value at 14 and the result I s , representing the current required to maintain the load at the pre-set total value, is applied to a PI current regulating circuit 8. The generator output is compensated by a circuit 15 for the internal resistance so that the voltage U remains proportional to speed irrespective of load current. Circuit 17 responds when a minimum operating speed is reached and its output may be used to light a signal lamp.
