Title: Improvements in keying or transmitting apparatus for high frequency signalling systems
IPC: H04L27/04
Filed: 1924-11-20
Abstract: 225,224. British Thomson-Houston Co., Ltd., (Assignees of Baker, W. R. G.). Nov. 21, 1923, [Convention date]. Thermionic modulating systems and apparatus.-Relates to keying systems of the type in which a negative bias applied to the grid normally prevents the production of oscillations, the bias being removed when the signalling-key is operated, so as to ensure a clear-cut signal, and a higher keying speed, whilst at the same time preventing any dynatron action. The grid and plate circuits of the oscillator 1 are back-coupled through an inductance 12 which is coupled through a coil 16 to the grid circuit of the amplifier 2, the output of which is fed through a storage circuit 21, 22 to a multiple-tuned aerial 23, 24. The plate circuits of the tubes 1, 2 are fed from a D-C source 7, 8 whilst the filaments are energized from AC mains 25 through transformers 26, 27. The grid condenser 13 is shunted by a choke 28 and resistance 29 in series with a second condenser 31, the latter being short-circuited (when the key 32 is down) through an associated relay 30. The grid side of the condenser 31 is negatively charged through a rectifier 36 fed from a transformer 34, the applied bias cutting off oscillation of the tube 1 except when the condenser 31 is shorted as the key 32 closes the relay 30. The grid 6 of the amplifier 2 is similarly biassed by a negative voltage derived from a transformer 41 across the mains 25. One end of the secondary coil 42 is connected to the anode of rectifier 44 and to the cathode of rectifier 43, whilst the other end of the coil is connected to the anode of 43 and the cathode of 44. The rectified half-waves charge the two condensers 45 in series so that the resultant voltage applied to the grid 6 through a choke 46 is double the voltage applied to the primary of the transformer 41. Specification 203,788 is referred to.

Abstract: 323,473. Marks, Sir G. C., (Du Pont Viscoloid Co.). Sept. 29, 1928. Ornamenting.-A process for making decorated articles, such as mirror backs, brushes, and manicure handles, consists in decorating one side of a diaphanous sheet and consolidating it with another sheet of material, with the decoration between the sheets, which are united by means of a binder containing a solvent for the two sheets. The design is preferably protected from the action of the binder by a coating of colour, such as zinc white, which may also be used when a non-solvent binder, such as a sheet of gelatine, is employed. The sheets may be of a pyroxy1ine composition or a cellulose acetate plastic, and the lower sheet need not be transparent. The design mav be applied by printing or 1ithography, and metallic colours, such as bronze, aluminium, silver, and gold, may be used. When the design is in colours, the deep shades are preferably applied first and the lighter shades afterwards. The binder for uniting the sheets may be a solvent cement, comprising bibutyl phthalate, acetone, and denatured alcohol, and the sheets are consolidated under heat and pressure. The design-bearing sheet or the composite sheet is provided with outlines 18 to faci1itate, the cutting- out of the artic1es.

Title: Electron guns
IPC: H01J37/29
Filed: 1971-06-15
Abstract: 1355365 Electron guns; ion pumps AMERICAN OPTICAL CORP 15 June 1971 [15 June 1970] 28003/71 Heading H1D An electron gun for an electron microscope comprises a field emission cathode 45, Fig. 4, surrounded by a shield electrode 90 operated at or near cathode potential and adapted to protect the cathode from excessive discharge voltages and preferably also forming a magnetic shield and an enclosure which can be evacuated to a lower pressure than the rest of the apparatus. A titanium coated filament 91 operated either continuously or discontinuously evaporates titanium on to the electrode 90 to getter reactive gases, and their action is assisted by cooling the electrode via a beryllium oxide ring 102 which conducts heat to a tank 100 filled with liquid nitrogen. An electrode 95 at 500-3000V accelerates electrons from the cathode and intercepts part of the beam thereby forming an electron cloud which tends to ionize any stray gas molecules which are then attracted to electrode 90, so that a local getter-ion pump is established. In this way the pressure within electrode 90 may be reduced to about 10<SP>-10</SP> Torr, whilst the rest of the apparatus is kept at about 10<SP>-6</SP>-10<SP>-7</SP> Torr by the pump 135. The cathode 45 may be 1000Š in diameter and is attached to a mount 51 crimped between two electrodes (of which one, 52, is shown in Fig. 4) connected by respective leads 80 and 81 to a terminal 77. The electrodes plug into an insulating post 55 secured to a metal shaft 60 received in a support plate 65 and sealed to the end cap 62 by a bellows 61. Four screws 66 (only two shown in Fig. 4) allow the plate 65 to be tilted in order to displace the cathode 45 in X and Y directions; a knob 68 allows the shaft 60 and therefore the cathode 45 to be moved longitudinally in order to focus the beam. A first anode 75 is connected through a resistance 83 to electrode 95 which is connected to input terminal 79, and a second anode 85 is maintained at 20 kV relative to the cathode. A plate 110 contains four holes ranging in diameter from 25 to 250 microns and is movable transversely; if this plate is fully retracted the seal 114 is withdrawn to allow the chamber 41 to be exhausted through a vent 125. For isolating the chamber 41 from atmosphere while a specimen is being changed, a plate containing an aperture 131 for the beam may be slid across the end of a tube 107 and sealed to it by a ring 143<SP>1</SP>. The chamber 41 is sealed by a ring at 113 and hinged at 152 so that it may be opened to replace the cathode.
