Title: Improvements in or relating to fading compensation in radio receivers
IPC: H04B14/08
Filed: 1940-03-18
Abstract: 539,793. Valve circuits ; frequency modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 18, 1940, No. 5040. Convention date, March 18, 1939. [Classes 40 (iii) and 40 (v)] In a system using a radio-frequency carrier which is modulated by a frequency modulated sub-carrier, interference is reduced by providing two channels for receiving respectively the sub-carrier and its second harmonic which are passed for frequency detection, means being provided for blocking that one of the channels which carries the weaker signal. The invention is described with reference to a picture transmission system. The transmitter is shown in Fig. 1. The variation in the light received from the picture 5 by the photo cell 6 changes the impedance of valve 8 and hence varies the frequency of oscillation of the neon tube-condenser arrangement 16, 13 in accordance with the brightness of the picture. This frequency modulated audio-frequency sub-carrier is applied by a transformer 19 to amplitude modulate a radio-frequency carrier in a transmitter 20, 201, 21 the signal being radiated by an aerial 22. Fig. 2 shows a receiver in which selective fading is overcome by employing separate channels B, A for the fundamental sub-carrier and the second harmonic respectively. The signal is received by an aerial 23 and applied to receiver 24 the output of which comprises the frequency modulated sub-carrier and harmonics. Band pass filter 27 passes only the second harmonic of the sub-carrier while band pass filter 28 passes only the fundamental. The subsequent stages of the two channels comprise limiters 29, 30 and frequency detectors 31, 32 the output from which comprise amplitude modulated waves which are combined and applied to an amplifier and rectifier 34 the output from which passes to a picture recorder 35. A suitable form for the limiters 29, 30 is shown in Fig. 5. The input consists of two coils 50, 51. connected to the anodes of a double rectifier 54 The live ends of the load resistances 55, 56 are connected to the grids of two valves 60, 61 the anodes of which are connected in push-pull to the primary of a transformer, the secondary 75 of which comprises the input of a frequency detector such as is shown in Fig. 6. This is in effect a low pass filter consisting of inductances 76, 77 and condensers 78, 79, 80 and possessing a characteristic having a straight part covering the band of modulation frequencies. In a modification, Fig. 3 not shown, a frequency doubler is inserted in channel B after the band-pass filter 28 so that, there being now only one frequency, the subsequent stages are common to both channels. To overcome phasing difficulties valve means are provided for blocking the channel having the weaker signal. A special circuit arrangement for selecting the preferred signal channel is described with reference to Fig. 9 not shown. Specifications 252,798, [Class 40 (iii)], and 352,621 are referred to.

Title: Improvements in or relating to the production of reversible alginate gels
Filed: 1947-02-21
Abstract: Reversible alginate gels are obtained by taking an aqueous alkaline solution of an alginate containing in addition to the alginate ions, ammonium and di-valent cations and a weak acid radicle not stronger than sulphurous acid, and gelling the solution by adding thereto formaldehyde, or a substance which yields formaldehyde in aqueous solution, in quantity just to make the solution acid.  Di-valent cations specified are those of calcium.  The setting may be controlled by the addition of sodium hexametaphosphate.  The gel may be redissolved in ammonium hydroxide and reset with formaldehyde alginate, solutions being maintained as concentrated as possible.  It is stated that instead of di-valent cations certain tri-valent cations may be used.  In an example, aqueous calcium alginate solution containing ammonium phosphate and hydroxide is set by the addition of a solution of sodium hexametaphosphate and formaldehyde and the resulting gel is redissolved in ammonium hydroxide and reset with formaldehyde solution.  Specifications 560,317 and 574,382 are referred to.

Title: Improvements relating to combustion apparatus
IPC: F02K3/10
Filed: 1944-03-20
Abstract: 607,196. Combustion apparatus for liquid fuel. POWER JETS. Ltd.. and DARLING, R. F. March 20, 1944, No. 5208. [Class 51(i)] The combustion of liquid fuel in an air stream for use for example in the jet propulsion of aircraft is effected by creating a turbulent zone in the air stream and injecting into such zone jets of fuel in an upstream direction, the jets being directed into the turbulent zone by one or more transverse air currents. In the apparatus shown, gases from combustion chambers 3 drive a turbine 2 which drives a compressor 1 supplying the combustion chambers 3. The gases from the turbine 2 pass through an annular duct 4 to a turbine 6 and to a central jet pipe 10. The turbine 6 drives a compressor 7 which entrains a stream of air into an annular duct 8 providing an annular jet. In its passage through the duct 8 the air enters chambers 12, 26 where turbulence of the air stream is produced by baffles 14, 22. Fuel is introduced into the chambers 12, 26 in an upstream direction through nozzles 18. 27 the fuel being deflected into the turbulent air zone by air jets entering through the walls of the chambers through openings at 19, 28. Additional air enters the chambers through openings 16, 29, 30. Air cooled supports 31, 32 support the elements from which the cooling air may enter the combustion chambers.

Title: Improvements in or relating to frequency control systems
IPC: H03C3/09
Filed: 1947-02-25
Abstract: 624,531. Automatic frequency-control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 25, 1947, No. 5434. Convention date, Jan. 22, 1946. [Class 38 (iv)] Two oscillation generators are kept in frequency agreement by heterodyning the output of one of them with quadrature phases of the other, and by comparing the phases of the beat outputs so as to produce pulses whose polarity depends on the direction of frequency deviation and from which frequency-connecting voltages are derived. The generator 1 supplies in-phase voltages to the outer grids of mixer valves 3, 4 and the generator 2 supplies to the inner grids voltages which are 90 degrees apart in phase by virtue of resistance-condenser feed circuits. The beat outputs are 90 degrees apart in phase, as indicated respectively in Figs. 2 and 3, the left-hand portion of Fig. 3 representing the beat wave when one generator is running faster and the right-hand portion the opposite condition. One beat output is amplified at the value 52 and is fed to a pair of reciprocally-coupled valves 62, or to a saturated amplifier, to produce square-topped waves which when differentiated. by the networks 73, 74, 76, 77 give two trains of output pulses phased respectively as shown in Figs. 4 and 5. These pulses are superposed on the sinusoidal output, Fig. 2, from mixer 4 and amplifier 52A to produce the waves shown in Figs. 6 and 7, either the left or right-hand portion of these figures being applicable according to the sense of the frequency drift. These waves are applied to diodes 75 which are biassed to pass current only when the sharp pulses add to the height of the crest of the sine wave. In this way, one or other of the diodes 75 passes pulses of current according to the sense of the frequency drift, these pulses being passed on to the grids of normally blocked triodes 85, causing one or other to pass a definite quantity of electricity per pulse. If a pulse passes through the left-hand triode of the tube 85, the condenser 94 co-operates with the oppositely-poled diodes 105, 106 and the condenser 95 to deposit a fixed negative charge on the condenser 109. A second pulse adds to this charge, and so on until the voltage applied to a frequency-corrector (e.g. a valve reactance), from the cathode-resistor of the valve 102, is such as to bring the two generators into frequency agreement. If, on the other hand, pulses pass through the right-hand triode of the tube 85, a positive charge is deposited on the condenser 109 and the frequency correction is made in the opposite sense. In order that the second and subsequent pulses may add the same amount to the charge on the condenser 109, the latter is connected to the grid of a valve 98 which has its cathode resistor connected to the rectifiers 105, 108 and condensers 95, 97.
