Title: Improvements in or relating to radio circuit-arrangements
IPC: H03G3/22
Filed: 1949-10-24
Abstract: 676,541. Frequency modulation. PHILIPS ELECTRICAL, Ltd. Oct. 24, 1949 [Oct. 27, 1948], No. 27247/49. Class 40 (v). In a radio receiver in which amplitude modulation is eliminated by a process of detection and negative feed-back as in Specification 659,598, the circuit is so modified as to permit of the use of a diode detector with an earthed cathode and with a single output filter from which both the feed-back voltage and the normal A.V.C voltage can be derived. The incoming F.M. wave is passed through the usual amplifying stage 1 and further frequency-changing or other stages (not shown) to an amplifier 2 having two control grids 14, 15. The output circuit 18 is connected to a diode 3 and load filter 4 across which detected A.M. is fed to the inner grid 15 of the valve 2, and A.V.C. voltage is fed through a smoothing circuit 22 to the control grid of the valve 1. The detected A.M. is amplified in the screen-grid circuit and fed with reversed phase from the impedance 7 through a condenser 8 to the outer control grid 14 of the same valve 2. The valve 2 is operated under such bias conditions that the A.M. modulates the wave passing through that valve in a negative or inverse sense, and so substantially annuls the unwanted A.M., as explained in the specification with reference to Figs. 2 and 3 (not shown). The H.F. feed may be to the grid 15 and the A.M. feed to the grid 14; and the A.M. may be amplified in the anode circuit instead of the screen circuit.

Title: Improvements in or relating to methods and apparatus for time conversion by means ofcathode-ray or like tubes
IPC: H01J31/62
Filed: 1939-10-05
Abstract: 577,068. Transmission systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and FALLOON, S. W. H. W. Oct. 5, 1939, No. 27306. [Class 40 (iv)] [Also in Group XL] The time scale of an electric phenomenon, e.g. a signal wave, is slowed down or speeded up by scanning a capacity target electrode of a cathode-ray tube by means of a beam modulated in accordance with the phenomenon to record a series of charges which are reproduced on a different time scale by a subsequent neutralizing scanning of the same side of the structure at a different speed by a second unmodulated beam. As shown, the target S is of straight strip form comprising a signal back-plate on a mica strip, the front of which is coated with good secondary emitting material divided into a large number of areas transversely of the strip. The strip is scanned by beams from two gun systems G<1>, G2 made operative in succession by any suitable means, the output when gun G<2> is operative, being applied to amplifier A over resistance R. When speeding up is desired, the target may be subdivided into two longitudinal halves, the elements of the two halves of which are electrically continuous, one half being secondary emissive and scanned by the first beam, whereas the other half is non-emissive and is scanned by the second beam. Rotary or other scanning with corresponding modification of the form of the target may be employed. The guns may be arranged to converge on the target to dispense with one set of deflectors for each gun or a common deflecting system may be used for both beams.

Filed: 1970-06-09
Abstract: 1312980 Insulating pipes INDUSTRIELE ONDERNEMING WAVIN NV 9 June 1970 [9 June 1969] 27931/70 Heading F2P A pipe 1 is surrounded over at least part of its length by a layer of thermally insulating material enclosed by a layer 10 of liquid and vapour impermeable material, the insulating layer being accommodated in sealed compartments by the layer 10 which at intervals extends radially inwardly to the pipe and includes an axially extending cylindrical portion sealed, directly or indirectly, to the pipe. Where the layer 10, of e.g. tubular foil, polyethylene, glass fibres and epoxy or polyester resin, surrounds the pipe 1, e.g. of metal, before the introduction of the insulating material, of, e.g., polyurethane reinforced by glass tissue, polyester tissue, polyethylene foil &c., polyester or epoxy resin, spacer rings 13 or helical springs 14 of differing diameter centralize the pipe 1 in the protective layer 10. Alternatively, the insulating material is applied to the rotating pipe 1 and the protective layer 10 is added in the form of tape or foil. The compartments are formed by applying a two-part electrically heated mould which locally contacts the protective layer 10 on to the pipe 1. More insulating material is added, and lining 24, e.g. of polyethylene, then covers the gap, and is sealed to the protective layer by sealing rings 5, as shown, or by welding, wherein the lining 24 and layers 10 are of thermoplastics materials. This form of insulating and sealing is used for the welded joints between pipes 1. Seals of self-curing butyl rubber can be used between the protective layer 10 and the pipe 1 at the compartment ends, or a sealing ring 8, of, e.g. glass fibres possibly reinforced by epoxy resin, bridges the gap between successive protective layers 10. Also sealing rings 7, e.g. of neoprene, self-curing butyl rubber, natural rubber &c., and/or rings 9, e.g. of tissue or non-woven material, lie between the ring 8 and the protective layers 10.

Abstract: 437,910. Aircraft. OEHMICHEN, E. E., Rue des Graviers, Valentigney, Doubs, France. Oct. 1, 1934, Nos. 28069 and 28070. Convention dates, Oct. 23, 1933 and Oct. 31, 1933. [Class 4] The supporting surface of an aircraft is constituted in part by an elongated flexible or rigid envelope 1 filled with air and in part by planes or fins 6, 7, connected thereto, the motor 10 and cabin 11 being rigidly secured below the envelope 1 so that an automatic stabilizing effect results, while the craft is raised and propelled by means of a pair of laterally disposed propellers 2, 2<1>. When not in flight the aircraft rests on the ground on shock-absorbers 4, 4<1> and 5 with the axis X, X<1> of the envelope at such an inclination B to the horizontal that the lifting effort of the screws 2, 2<1> is directed substantially through the centre of gravity G of the whole craft. In consequence, as soon as the craft is raised, since the centre of volume V of the envelope is above G, the envelope tends immediately to assume its normal position of flight. To obtain a directly vertical take-off, therefore, an auxiliary screw 3 is provided to counterbalance the restoring couple brought into play. Subsequently, the effort of the screw is gradually diminished, the envelope gradually assumes an horizontal position, and the screws 2, 2<1>, now exerting their effort, in an inclined direction, both sustain and propel the craft. In order to vary the effort of the screws 3, these may be of a variable pitch and inclination; or, in substitution therefor, a balancing weight may be adapted for movement longitudinally of the craft. The shock-absorbers or landing feet 4, 4<1> are preferably retractable, and landing slides 12, 12<1> may be used in place thereof. The air in the envelope is not necessarily entirely enclosed thereby, and more than one envelope may be provided. Specifications 375,931, 380,210, and 393,687 are referred to.
