Title: Improvements in radio-receiving apparatus
IPC: H04N5/60
Filed: 1938-07-27
Abstract: 516,901. Wireless receiving systems. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. July 27, 1938, No. 22391. [Class 40 (v)] In a receiver having a common frequencychanger for television and accompanying sound and also adapted for ordinary broadcast reception, the broadcast signals, preferably after a preliminary change of frequency, are also applied to the same frequency-changer at a carrier frequency not substantially greater than and possibly much less than the intermediate frequencies of the television and accompanying sound at the output of the common frequencychanger, and selective means capable of distinguishing between adjacent broadcast stations are introduced into the broadcast channel in such a way that they do not restrict the television band. The Figure shows alternative input paths A, B for the television and accompanying sound and for the broadcast, respectively, a common frequency-changer 3, and separate outlet paths, one 6 used in common for both sound signals and the other 9 for the vision signals. The station-selecting means may be permanently connected in the separate broadcast path at 15a, or may be subsequent to the common frequency-changer 3 in which case it may be switched in, e.g., at 15b, when changing-over from television to broadcast reception. Alternatively, circuits in the common path may be modified as regards selectivity when change-over takes place, e.g., by connecting condensers across the coupling circuits, or there may be two parallel paths one passing a narrow band around one I.F. and the other a broad band around a different I.F. Where the broadcast input frequency to the frequencychanger 3 is the same as the I.F. output of the television sound, oscillator 4 is suppressed during broadcast reception and the frequencychanger acts merely as an amplifier, but where it is less, the frequency of oscillator 4 is suitably changed to give the same output frequency from frequency-changer 3 for both sound channels. Specification 453,484 is referred to.

Abstract: 1,188,184. Control of A.C. motors. JUNGNER INSTRUMENT A.B. 17 May, 1967 [17 May, 1966], No. 22998/68. Heading H2J. A servo amplifier supplies a pulse-duration modulated voltage to a control winding 2 of a two-phase motor which has a reference winding 3. A square-wave generator G produces a voltage having a frequency substantially higher than the reference frequency, this voltage being integrated in network R3, R4, C2, and applied to the base of a transistor Tr2 of a flip-flop circuit. An input signal is applied through network R1, C1, to the base of a transistor Tr1 of the flip-flop circuit. A resultant pulse-duration modulated voltage is derived at the collector of transistor Tr2 for feeding the control winding 2 through an amplifier F. A 60-degree phaseshift is introduced by the network R1, C1, and a further phase-shift of 30 degrees by the integrating network and flip-flop, so that the modulated voltage is in quadrature with the reference voltage. One end of the control winding 2 is earthed, the other end being connectible alternately to positive or negative lines through respective transistors. Protective diodes are provided for the transistors, Fig. 2 (not shown).

Title: Frequency divider

Filed: 1975-05-23
Abstract: 1507822 Transistor frequency dividers EBAUCHES SA 23 May 1975 [29 May 1974] 23042/75 Heading H3T A frequency halver comprises 8 field effect transistors arranged effectively as shown. A pulse at El, which pulse occurs together with a #2 pulse, causes T6 to charge node b from the power supply line P. A #1 pulse then causes node e to charge therefrom via T7 rendering T5 conducting so that the next El pulse together with the concurrent #2 pulse at the gate of T3 allows the gate of Tl to discharge. T1 becomes non-conducting and accordingly the next #1 pulse passes through E1 to the output terminal E2. This pulse also causes T8 to discharge the gate capacitance of T5. The next #1 pulse, finding T5 now non-conductive, recharges point a and the following #2 pulse allows the gate of T1 to charge via T3 rendering T1 conductive whereby the next #1 pulse does not produce an output. The cycle now repeats. In Fig. 3 some functions are separated. Pulse E1 charges b via T6 and charge is transferred to node e at #1 so that T5 becomes conductive. The next El pulse at the gate of T4 therefore allows the gate of T 1 to discharge via T5 and T4 and thus the next #1 pulse passes to output 2. This pulse also causes T8 to discharge the gate of T5 allowing the gate of T1 to recharge at #2 via T3 from point f previously charged via T2, so that the next #1 pulse does not pass to the output. In Fig. 5 the input (E) to T4 is derived directly from #2. A #2 pulse charges f via T6 and the next #1 pulse transfers the charge via T7 to e rendering T5 conductive so that the next #2 pulse completes via T3 and T4 the discharge path for the gate of T1. The next #1 pulse accordingly passes to the output E2 and via T8 discharges f so that at #1 E is discharged and T5 becomes non-conducting allowing the cycle to repeat.

Title: Improvements in or relating to photo-electric cells
IPC: H01J40/18
Filed: 1935-08-16
Abstract: 461,434. Photo - electric cells ; circuits. JOHNSTONE, D. M., and BAIRD TELEVISION, Ltd. Aug. 16, 1935, No. 23079. [Classes 39 (i) aud 40 (v)] Electric impulses intermittently inhibiting the cathode emission from a photo - electric cathode are applied to a discharge tube wherein electrons from a cathode are accelerated to and fall upon a fluorescent screen, the fluorescence light causing further electrons to be-emitted from the screen by the photo-electric effect. The anode circuit may comprise an oscillatory potential source 11 so that the tube is operative only when the anode 9 is positive, potential variations corresponding with the variations in intensity of the incident light appearing across the resistance 12. The fluorescent screen may be deposited on the anode. The inhibiting impulse is applied at a frequency high compared with the greatest frequency of variation of the emission current. The " after-glow " of the fluorescent screen may be made brief by adjusting the temperature of the screen or by flooding it with infra-red radiation during the inoperative periods. The primary cathode emission may be an emission of secondary electrons caused by the impact of primary electrons on the cathode, which primary electrons may pass through the apertured anode of a television electron camera.
