Title: An improved furnace for fluidised bed combustion of solid fuels
IPC: F23C10/00
Filed: 1958-06-10
Abstract: 858,813. Pulverulent fuel furnaces. DING LERWERKE A.G. June 10, 1958 [June 11, 1957; Nov. 21, 1957; April 3, 1958], No. 18565/58. Class 51 (1). In a furnace having a fluidized bed 2 of solid fuel, secondary air is blown upwards through a slit 4 forming a Venturi nozzle between the primary and secondary combustion chambers 3 and 5. The air supply nozzles 6 project into the combustion chamber 3, and have tubes 9 for coolant associated with them. The single row of nozzles 6 may be replaced by a double row of nozzles, the cones of air from the nozzles intersect at the narrowest part of the slit. The cooling tubes of one row of nozzles may cross the combustion chamber while the cooling tubes of the other row of nozzles are bent back to return through the same wall. Further nozzles may deliver air at a plane midway up the combustion chamber, or nozzles projecting through the fuel bed may terminate at several different planes, all the nozzles forming a checkered pattern in plan. In a further modification, Fig. 7, nozzles 17 projecting into the combustion chamber deliver air tangentially to an imaginary circle within the chamber. The pipes leading to the air supply nozzles may be double walled to provide cooling tubes, or one or more cooling tubes may be welded to the air pipes, or the air supply pipes may be formed by a ring of cooling tubes welded together. The air supply tubes 29, Fig. 12, may be enclosed in heat-resistant ceramic jackets 28, a length of tube projecting in order to preheat the air. The tubes may be adjustable in height, and carry nozzles 32 of any desired shape. The tubes may be rotatable together with the nozzles to improve the distribution of air. Air may be supplied through holes 33 in the sides of the tubes. The pipes supplying air tangentially may be mounted on a ball-and-socket joint outside the furnace so that they may be tilted, or moved to project air tangentially to different imaginary circles, Figs. 13 and 14 (not shown). In another embodiment, Figs. 15-18 (not shown), a sleeve projects from secondary combustion chamber into the primary combustion chamber, and the combustion air is at least partly delivered tangentially.

Abstract: 1,180,929. Gas turbine &c. combustion chambers. ENGLISH ELECTRIC CO. Ltd. April 26, 1967 [April 28, 1966], No.18655/66. Heading F1L. Combustion apparatus, e. g. for gas turbine engines, comprises a flame tube having an open downstream end and an end wall enclosing the upstream end, fuel injection means for injecting fuel into the tube near the upstream end, air inlet openings situated intermediate the ends of the tube, and means for directing the air flow from the openings initially in an upstream direction towards the closed end wall, the fuel injection means comprising fuel nozzles circumferentially spaced around the tube, each with an axial location intermediate the air inlet openings and the closed end wall, for delivering substantially the whole combustion fuel supply in the form of fuel sprays substantially radially into the tube, and the closed end wall being shaped to deflect the initial upstream air flow radially inwards whereby to return it centrally within the tube in a downstream direction. In Fig. 1, primary air enters the flame tube 12 through a row of swirl vanes 17 and is deflected as shown by a ring 21 carried by a partition 20, whereby it flows in an upstream direction over the faces of burners 23 before being reversed in direction by an end wall 13 so as to flow in the downstream direction in the region substantially in the centre of the flame tube. Combustion is facilitated by a recirculation of the burning gases as shown. Further air enters by way of rows of swirl vanes 18, 24 and is deflected in the downstream direction as shown. The rows of swirl vanes 17, 18 may be formed by continuous corrugated parts. In Fig. 4, the primary air passes axially through swirl vanes 27 connecting the upstream end 14 of the flame tube to a conical portion 42. Further air enters radially through swirl vanes 38, 24 and is deflected axially as shown by a ring 34 carried by a partition 33. The conical portion 42 may be replaced by a cylindrical portion (32, Fig. 3, not shown), the axial swirl vanes 27 then being replaced by radial swirl vanes (17). In Fig. 2 (not shown), in which the conical portion 42 is again replaced by a cylindrical portion (31), the further air enters in the downstream direction through axial swirl vanes (28, 34). In all constructions, the flame tube 12 and the outer casing 11 may be either cylindrical or annular.

Patent GB-146997-A (GB)
Title: A method of and apparatus for receiving radio signals
IPC: H04B1/12
Filed: 1920-07-06
Abstract: 146,997. Hogan, J. L. Nov. 27, 1916, [Convention date]. Directive wireless signalling.-Apparatus fur reducing interference from atmospherics comprises two receiving-aerials, one or both of which are of the directional type, connected differentially to the receiving-instrument, one of the aerials being so arranged that it gives minimum response to signals from the desired direction, whilst both aerials are affected equally by atmospherics which are consequently baianced out in the receiving-instrument. Fig. 1 shows one arrangement for heterodyne reception, Fig. 8 shows another arrangement without heterodyne, and Fig. 3 shows a modification employing an electrostatic telephone receiver. As shown in Fig. 1, a directive aerial 31 is set up to give maximum response to the desired signals, and an auxiliary directive aerial 32 is arranged to give minimum response to such signals. Both are affected substantially equally by atmospherics. The secondary circuits include detectors 8, 17, and heterodyne sources 25, 26 have their circuits inductively related to the secondary circuits, giving beat tones through the receiver 3. This receiver is oppositely connected to the two circuits so that static signals which are of substantially equal value are balanced out. The desired signals, however, produce little effect on the aerial 32, and are consequently heard in the receiver. A single heterodyne source may replace the two sources 25, 26. In the modification shown in Fig. 8, loop aerials 35, 36 are employed, one of which 36 is placed so as to be irresponsive to signals from the desired direction S. The detector circuits are connected respectively to oppositely-wound transformer coils 10, 19, the third coil 11 being connected to the telephone 3. Separate telephones may be placed in circuit with the coils 10, 11 to enable independent tuning and other adjustments to be made, and when the effects of atmospherics in the two telephones is substantially identical, both are cut out by short-circuiting switches. The circuit of the telephone 3 may include a condenser for tuning to group frequency. The signal-receiving aerial 31 or 35 may be a vertica'i non-directional aerial. The auxiliary aerial 32 or 36 may also be a vertical aerial screened from the desired signals by a number of vertical grounded wires placed symmetrically round it. The crystal detector may be replaced by a thermal or thermionic detector; or an electrostatic telephone may be employed as shown in Fig. 3. In this arrangement, the telephone 29 is placed in a circuit, including coils 7, 16 coupled to the aerials 31, 32 and a coil coupled to a heterodyne circuit 30. This arrangement depends for its action partly on the difference in signal strength received upon the two aerials, and partly upon the phase difference of the signal waves.
Patent GB-1509225-A (GB)
Title: Telecommunication system
IPC: H04M3/00
Filed: 1975-05-06
Abstract: 1509225 Automatic exchange systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 May 1975 [9 May 1974] 18959/75 Heading H4K In a telephone system wherein the paths between some of the subscriber stations and an exchange each include a pair of modems, an arrangement is provided in each path for switching the modem nearest to the exchange out of the path. The arrangement is used to switch out modems 7 and 13 in a connection between two subscriber stations 1, 19 where the same form of transmission is used on the paths 6, 14. To this end the modems 7, 13 next to the exchange are each provided with a signal detector 34, a tone generator 31 and a timing circuit 30, Fig. 2, the modems 5, 15 being similar to the modem of Fig. 2 except that the units 30-36 are omitted. When subscriber station 1 goes off hook, remote concentrator 3 sends a seize signal to the exchange via a signalling wire 25 of path 4 signalling modulator 21, of modem 5, the outgoing channel 37 of path 6, signalling demodulator 23 of modem 7 and signalling wire 28 of path 8, the exchange sending back an acknowledge signal via the return signalling path. Dialling information is then transmitted over said signalling path used for the seize signal to the exchange 9 which then establishes the call to subscriber station 19. The concentrator 19 sends a seize signal back to the exchange 9 in response to the incoming call, which signal causes the timer 30 in modem 13 to enable the signal generator 31 to send a continuous pilot signal over the speech wire 27 of path 12 to the exchange which couples the signal to speech wire 26 of path 8. Pilot signal detector 34 of modem 7 responds to the signal to switch over contacts 32, 35, 36 to cut out of circuit the speech modulator and demodulator 20, 23. The output noise level of modulator 23 of modem 5 is then coupled to speech wire 27 of path 8 and hence via wire 26 of path 12 to the pilot signal detector 34 of modem 13. By choosing the pilot signal frequency to be a frequency which will be present in the noise frequency spectrum of the modulators, the detector 34 of modem 13 can be separated by the noise level output of modulator 20 of modem 5 to cause contacts 32, 35, 36 of modem 13 to operate. The contacts 32, 35, 36 of modem 7 are then held operated by the noise level output of modulator 20 of modem 15, the pilot signal generator 31 of modem 13 eventually being switched off by timer 30. The detectors 34 may include threshold circuits so that, if the paths 8, 12 are too long for suitable transmission of the speech signals in the form used on paths 6, 14, the pilot signal will be so attenuated that it can not cause the modems 7, 13 to switch out of circuit. The form of transmission of paths 6, 14 could be PAM, PCM or delta modulation. Time division multiplexing may be employed and paths 6, 14 could be radio carrier links. However, no details of such systems are given.
