Title: Improvements in or relating to combustion chambers
Inventor: SOLTAU WILLIAM ERNEST
IPC: F23R3/16
Filed: 1956-04-03
Abstract: 809,514. Gas turbine plant. BRISTOL AERO-ENGINES Ltd. March 20, 1957 [April 3, 1956], No. 10215/56. Class 110 (3). [Also in Group XII] A combustion chamber 1 is of annular form, being disposed about an axial centre line 4 between a compressor 2 and turbine 3, the last two rows of the compressor rotor vanes 5, 6 and the last row of stator vanes 7 being shown. The combustion chamber comprises an inner wall 20 and an outer wall 21, an annular partition 22 being disposed between the inner and outer walls 20, 21 and extending from the inlet of the chamber to an intermediate part thereof. The partition 22 divides the upstream portion of the combustion chamber into an inner annular passage 26 through which dilution air flows from the compressor outlet through the inlet 24 with no reduction in its swirl velocity, and an outer annular space 25 which constitutes a combustion zone into which air flows from the compressor outlet through the inlet 23, likewise with no reduction in swirl velocity. The outer wall 21 is sharply divergent at 27 so that a toroidal eddy is formed at 28 into which fuel is injected through injector 29. The space 30 downstream of the partition constitutes a mixing zone in which dilution air from the passage 26 mixes with combustion products issuing from the combustion zone 25. The gaseous mixture flows between guide vanes 19 and impinges on turbine rotor blades 18. The outer wall 21 of the combustion chamber may be double-walled as shown, to permit flow of cooling air therethrough, the cooling air finally discharging through the hollow guide vanes 19 into an annular collector 31 and thence into the flow of combustion gases. The partition 22 is supported at its inlet end by means of vanes 33 which extend between the inner and outer walls 20, 21 and at its downstream end by means of vanes 34 which extend from the inner wall 20. The vanes 33, 34 and 19 do not greatly influence the swirl of gases passing therethrough so that the swirl of the air leaving the compressor remains substantially constant. The invention is also applicable in the case of an exhaust reheat combustion chamber of a gas turbine engine, in which case the exit of the chamber is wholly circular in form, and guide vanes at the chamber outlet are disposed so that the hot gases are discharged in an axial direction.

Filed: 1951-05-03
Abstract: 687,763. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 3, 1951 [May 6, 1950], No. 10394/51. Class 40 (iv). A relay chain circuit KS1 for allotting finders or other common apparatus is provided with a differential relay Y having one winding in series with the chain circuit so that it is operated by a start potential only if the circuit is incomplete. As shown, two groups of subscribers are served by two groups of primary finders, each acting as a reserve for the other, with allotting circuits KS1, KS2 and differential relays Y, Z. In normal operation, a start potential energizes relay IB of the allotted primary finder. This relay connects up the rotary magnet D and remains locked until the primary finder is found by a secondary finder. When the calling line is found, T energizes and operates switching relay IG which extends the allotting circuit. If all finders of a group are busy, or if the allotting circuit is faulty, the operation of Y or Z extends a start potential to the allotting circuit of the other group, and in the latter case makes a circuit for an alarm relay AL, this circuit being opened in the former case by the relays T of the busy finders.

Title: Negative feedback phase detection receiving equipment
IPC: H03G3/20
Filed: 1964-03-12
Abstract: 1,010,446. Frequency modulation receiver; automatic gain control. NIPPON ELECTRIC CO. Ltd. March 2, 1964 [March 18, 1963], No. 10467/64. Headings H3Q and H3R. In a negative feedback receiver for frequency modulated waves, the feedback is low when the input is low to give high sensitivity and is high when the input is high to give high quality. In Fig. 1 signals from a source 100, which may be an aerial, are converted to intermediate frequency in unit 15 and amplified in I.F. amplifier 17. The output of amplifier 17 passes to a phase detector 21 the output of which is amplified by a baseband amplifier 23 which supplies an output terminal 25 and also supplies negative feedback to local oscillator 19 so that the frequency and phase of the latter follow that of the I.F. signal, the oscillator being 90 degrees out of phase with the signal. One output of oscillator 19 passes to the phase detector 21 and another output is phase shifted by 90 degrees in unit 31 to bring it into phase with the I.F. signal. The output of unit 31 and an output of I.F. amplifier 17 pass to a coherent detector 32 which produces an output proportional to the I.F. signal and unaffected by noise. An output from I.F. amplifier 17 passes to a peak value detector 33 which produces an output proportional to the peak value of the I.F. signal including any noise component. The detectors 32 and 33 are adjusted to produce equal outputs at high signal levels, and at low signal levels detector 33 produces the higher output. The two outputs are added in unit 34 and amplified in a D.C. amplifier 35 to provide an automatic gain control signal for the I.F. amplifier 17. Alternatively the unit 34 may supply the difference of the two outputs to amplifier 35, and as further alternatives the output of amplifier 35 may be used to control the detection sensitivity of detector 21, the modulation sensitivity of oscillator 19, or the gain of amplifier 23. In modifications, Figs. 4 or 5 (not shown), the difference between the outputs of detectors 32 and 33 is used to control the gain of amplifier 23 or the modulation sensitivity of oscillator 19 respectively, and a second coherent detector similar to detector 32 supplies A.G.C. to the I.F. amplifier 17. Specification 911,495 is referred to.

Abstract: 586,321. Valve generating circuits. PATTAMALY, E. S. V. June 2, 1944, No. 10662. [Class 40 (v)] In a valve generating circuit, the feed-back, obtained from a centre-tapped anode transformer 12, is connected to two similar grids g<1>, g<2> so that the applied voltages are 180 degrees out of phase. By this arrangement the frequency obtained in the output transformer 17. is twice the fundamental frequency' of the tuned circuit 12, 16a, 16b. Bias, by battery 26, is applied such that the anode current due to one grid is cut off as the current due to the other grid begins to flow. In Fig. 2 (not shown), a valve having four similar grids is employed and the output from the anode is passed through two transformers so as to produce a two-phase voltage for feeding to the four grids. In this way the frequency obtained is four times the fundamental frequency of the tuned circuits. By inserting a suitable filter in the output, higher harmonics may be selected.
