Abstract: 184,875. British Thomson - Houston Co., Ltd., (General Electric Co.). May 20, 1921. Vacuum tubes.-A thermionic valve having a cathode 2, Fig. 1, anode 3, third electrode 4, and discharge-controlling grid 5, is connected to circuits such that secondary electrons are emitted by the third electrode 4, but in decreasing numbers with increase of the potential of. this electrode, while the potentials of the grid 5 and third electrode 4 oscillate with different frequencies. For this purpose, oscillations received by an aerial 9 may be imposed on the third electrode 4 by means of a transformer 10, the circuit of the electrode 4, battery 7, and cathode 2 being tuned by means of a variable condenser 11. The circuit of the grid 5 and cathode 2 may contain a battery 8 such that a negative resistance effect is obtained between these electrodes. Oscillations are thus produced in the circuit and are tuned by an inductance 12 and condenser 13 to a frequency slightly different from that of the signals. A battery 6 maintains the anode 3 at a constant potential, the potential of the third electrode being lower than this, but higher than the range over which a negative resistance effect is obtained; preferably this potential corresponds to the second point A, Fig. 2, at which the voltage-current curve crosses the zero current line. The current in the circuit of the third electrode then consists of groups of current impulses in one direction alternating with groups in the opposite direction, and can be detected by a telephone 14.

Title: Frequency synthesisers
IPC: H03L7/23
Filed: 1971-05-11
Abstract: 1349721 Automatic frequency control MARCONI CO Ltd 11 May 1971 [15 May 1970] 14373/71 Heading H3A A frequency synthesizer comprises: means 5, 6, 7 for releasing from a reference oscillator 4, in each of a first series of equal time periods, such a number of pulses as to produce a first predetermined number of pulses per second; a voltage controlled oscillator 8 producing a second predetermined number of pulses per second; n means for subtracting pulses from the controlled oscillator output pulse train, each of which n means other than the first subtracts pulses during time periods which have durations ten times those of the preceding means, thus producing a third predetermined number of pulses per second; and means 10, 12 for comparing the first and third predetermined numbers of pulses per second to produce an error signal which adjusts the frequency of the voltage controlled oscillators. The reference signal is derived from a voltage controlled oscillator 4, locked to a multiple of a standard frequency by means of an auxiliary control loop comprising standard source 1, comparator 2 and divider 3. The output of oscillator 4 is fed to one input of a gate 5, and also to the trigger input of a counter 6, the output from which is applied to the other input of gate 5. Pulses from oscillator 4 are counted by the counter up to a maximum predetermined count set by loading device 7. At this point an output from the counter closes gate 5 to prevent transmission of further reference pulses to coarse and fine comparators 10, 12. The maximum count of counter 6 is set so that the average number of pulses per second fed to the comparators is equal to the whole number part of a required output frequency of the synthesizer. The other inputs to the coarse and fine comparators 10, 12 are derived from gate 9 which is arranged to be opened for predetermined time periods depending on the required output frequency. The whole number part is determined by the maximum count of counter 17 and the decimal part is determined by the counter 19 of a number of units, Fig. 2, connected in cascade. These counters are arranged to switch bi-stable 16, which controls gate 9, for periods of time governed by dividers 21.

Abstract: 517,803. Optical sound-reproducing apparatus. KOLB, O. K. May 17, 1939, No. 14762. Addition to 501,218. [Class 40 (ii)] Apparatus for reproducing either from asymmetric (push-pull) or normal sound film records, as described in the parent Specification, is modified by providing in the optical system a single prism which is utilized for dividing the beam when a push-pull record is being employed, and which is rendered ineffective when the reproduction is from a normal record. In the arrangement, Fig. 1, an image of the sound track on a film 2 is formed on a slit (not shown) provided in a mask at the back of a lens 6. The slit may be made by engraving in a metallic layer on the lens. A prism 7 extends over half the slit, and is integral with a parallel-sided glass block 11. In the position of the parts shown (or alternatively, with the prism in close contact with the lower half of the slit and the upper half uncovered), the modulated light beam is split so that half of it falls on the cathode of a cell 9 and the other half on the cathode of a cell 9<1>. This enables push-pull reproduction to be effected. For use with a film having a normal sound-track, the prism is displaced or otherwise rendered ineffective, so that the slit is either uncovered or covered only by parallel-sided glass. By this means, the whole of the modulated beam is caused to fall on the cell 9<1>.
