[Class 40 (v).] Relates to the use of transmission lines for obtaining selectivity in receivers and stability in oscillators. Fig. 4 shows the application to a superheterodyne receiver particularly adapted for operating on short wave-lengths. The intermediate frequency amplifier 74 is stabilized by lines 82, 84, 86 which may be coupled inductively, capacitively, or conductively and are of different lengths to avoid interference from adjacent channels not excluded by the tuned circuits. The oscillator 72 may be stabilized by a line 90 which is adjustable in length by movement of the shield 92 by uni-control means which also controls the tuning condensers. In a modification, Fig. 5, the length of the line is adjusted by sliders 108. With a push-pull arrangement, Fig. 6, the lines 58, 60 may be of different length to provide selectivity against adjacent channels and in a multi-stage amplifier or oscillator, Fig. 7 (not shown), an additional line coupling the output of one valve to the input of a preceding valve may be used for the same purpose. Instead of an aperiodic line as described in Specification 342,976 a resonant line having standing waves formed thereon as described in Specification 358,264 may be used. Alternatively lines on which both travelling and standing waves are formed may be used as described in Specification 375,698.

Title: Improved means for deriving an electrical potential and for utilising said potential in signalling and indicating systems
IPC: H04B14/00
Filed: 1944-04-28
Abstract: 582,457. Secret transmission. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 28, 1944, No. 8030. Convention date, April 29, 1943. [Class 40 (iv)] [Also in Groups XXXVI and XL] A sinusoidal function of an initial variable voltage is derived by phase-modulating a carrier by the initial voltage and mixing the resultant with a suitable phase of the unmodulated carrier in a detecting or rectifying circuit, the output constituting the desired sinusoidal function. As shown in Fig. 1a, the initial voltage E, which may represent speech or other signals, phase-modulates a carrier S in a modulator PM. The degree of phasemodulation is increased by a frequencymultiplier HG which feeds in push-pull a balanced rectifier circuit D. The carrier, multiplied in frequency at HG<1> to the same degree and adjusted in phase at PS, is applied in like phase to the balanced rectifiers D. The output across the rectifier load resistances represents a sine or cosine function of the voltage E according to the adjustment of the phase shifter PS and in the arrangement shown one rectifier D delivers the sine function and the other D<1> the cosine. Fig. 1b shows the inverse process of re-converting these functions into the initial voltage E. The inputs are applied respectively to balanced modulators BM, BM1 in push-pull, and an oscillator S<1> feeds carrier co-phasally through phase-adjusters PA, PA1 to the modulators. The combined output from the modulators is a phase-modulated carrier with a phase deviation proportional to the voltage E. This is preferably detected by a frequency-modulation detector FM and is passed to the output terminals through an integrating circuit RC. To provide a secret radio system the respective sinusoidal functions may be transmitted over separate radio channels which may comprise different carrier frequencies, or a single carrier with different types of modulation, e.g. amplitude and frequency.

Filed: 1941-06-26
Abstract: 550,252. Moulding compositions. LEADER, S. A. June 26, 1941, No. 8041. [Class 2 (iii)] A resilient moulding or thermoplastic composition suitable for the manufacture of artificial joints, hands, fingers, noses, ears, lips. tongues and linings or additions to dentures and other polymerized products comprises polymeric and/or monomeric methyl methacrylate and, as a plasticizer, an unsubstituted phenol or mixture of phenols, the phenol being present between 33 and 150 per cent. calculated on the weight of methacrylate. Specified phenols are thymol, phenol, creosote and guaiacol. Up to 10 per cent. of the methacrylate may be replaced by other acrylate or vinyl resins; and up to 50 per cent. of the phenol may be replaced by other plasticizers, e.g. dibutyl phthalate, tricresyl phosphate. Resilient articles are made by heating the composition in a mould, and material is obtained suitable for injection moulding by fusing the composition preferably by heating between 60 and 100‹C., if desired with addition of an anti-catalyst, e.g. hydroquinone. Tin or silicate lined plaster moulds may be used, but if the monomer i, used it is preferred to heat under reflux with stirring. The powdered composition can be sprayed through a hot nozzle to give a rubberlike deposit, and this process may be used for flexibly uniting sections of hard methyl methacrylate. It may also be passed between hot rollers to form sheets resembling dental rubber. The composition may also' include a solvent for the phenol, pigments and dyes ; specified are titanium dioxide and Sudan III. Composite hard and soft moulded articles may be obtained by distributing. suitable compositions in the mould. The greater the proportion of phenol the softer the product. The compositions may be used with other polymerized vinyl and methacrylate products, e.g. the "bone" of an artificial finger is of non- or slightly plasticized polymerized methyl methacrylate, the composition forming the "flesh". If necessary trimming may be carried out with a hot body followed by wiping with a solvent, e.g. chloroform, monomeric methyl methacrylate. Specification 358,534 is referred to.
