Title: Regeneration of carrier transmitted digital signals
IPC: H04L27/06
Filed: 1976-02-26
Abstract: The additional transmission of digital signals via transmission paths set up for the transmission of low-frequency and carrier-frequency analog signals is possible provided that the digital signals are shifted to a higher frequency range by modulation with a carrier which has a suitable frequency and phase. One of the sidebands produced during the modulation is adequate for transmission, although this cannot be directly regenerated. The transmitted sideband is therefore first equalised, amplified and then fed to a modulation device (M) and also to an arrangement (TA) for clock and carrier derivation in which both the carrier (C) required for modulation and the clock (L) required for time regeneration are generated. The modulation produces a digital signal which is regenerated in a conventional regenerator (R) for digital signals which contains an amplitude regenerator (AR1) and a time regenerator (ZR). The described method and the arrangement are particularly suitable for use in PCM systems which also use an existing cable installed for carrier-frequency telephony. <IMAGE>

Title: Process and apparatus for burning gaseous liquid or pulverulent fuels and for recovering contained solids in molten condition
IPC: F23C3/00
Filed: 1924-03-25
Abstract: 231,320. Marks, E. C. R., (Peoples Sarings & Trust Co.). March 25, 1924. Open tray, blowpipe, and pulverulent-fuel burners.- Air is caused to whirl in a downwardly moving column round the inner periphery of a furnace burner and is supplied with liquid, gaseous, or pulverulent fuel at the bottom of the columns. Fig. 1 shows a vertical section and Fig. 3 a horizontal section of a steam boiler furnace. Air supplied through a pipe 4 to an annular chamber 4' enters the cylindrical burner through a multiple tuyere ring 15 composed of a large number of overlapping blades 17 separated by slit openings 18, which cause the air to circulate rapidly round the inner periphery of the ring 15. A brick or metal ring 14 overhanging the top edge of the ring 15 causes the peripheral whirling column of air to travel downwards, where it meets and mingles with combustible gas supplied through a similar pipe 5 and multiple tuyere ring 16. The mixture passing down to the bowl or hearth 12 is ignited, and the burning whirling column reacting against the bottom of the bowl escapes upwards along the central axis of the burner and through the central opening in the ring 14 to heat the boiler. The bottom of the hearth has a central opening 12<1> through which slag from dust-laden gases is discharged. If the combustible gas is too lean, enriching fuel may be fed through tuveres in the side of the hearth 12. The lower multiple tuyere ring may be dispensed with, when pulverulent fuel or oil is to be burnt, the fuel being them fed in through pipes at the sides of the shallow hearth.

Title: Improvements in or relating to signal storage cathode ray tubes
Inventor: BANKS GEORGE BALDWIN
IPC: H01J31/62
Filed: 1955-03-17
Abstract: 783,719. Television pick-up tubes. ENGLISH ELECTRIC VALVE CO., Ltd. Nov. 1, 1955 [March 17, 1955], No. 7778/55. Class 39(1). In a cathode ray storage tube with separate reading and writing beams, grids 9, 10, Fig. 2, are interposed in the paths of the respective beams and are given different D.C. potentials. Writing takes place at or below the second cross over point (S.E. 7, 1) and reading at or near the maximum of the SE-primary voltage curve, between the first and second cross over points. In writing the secondaries generated at the target by the signal modulated electron beam cannot pass suppressor grid 9 which is 100 volts negative to signal plate 7 and the discrete storage areas 8 can therefore charge negatively by varying amounts up to the potential of grid 9; the latter is so close to the target that SE redistribution and the consequent production of shading signals is prevented, the secondaries returning approximately to their point of origin. Collecting grid 10 associated with the reading beam is earthed so that the voltage between the discrete areas of the mosaic 8 cannot exceed 100 volts, i.e., the voltage difference of the two grids. The grids 9, 10 are of fine mesh and are spaced about 4 mils. from the target, and the signal plate area is less than that of the mosaic so its capacity is small. The discrete mosaic elements have areas of 8 x 0À06 mm. and are spaced apart by 0À005 mm., and are formed on glass plate 6. The wall coating 12 and signal plate 7 are both earthed the latter via output resistance 11. The invention thus minimises secondary electron redistribution, prevents temporary or permanent breakdown of the insulation between the discrete mosaic areas and improves reading and writing efficiency secondary electron redistribution causes shading signals and temporary breakdown of insulation between discrete mosaic areas can cause generation of spurious signals.
