In a " multi-standard " television receiver the I.F. amplifiers 5 have rejector circuits Rej 1, 2, 3, 4 including variable capacitance diodes 24, 26, 27 controlled by D.C. bias so that the required selectivity for the particular standard in use can be selected by switching or varying the voltages applied to the diodes at 25, 28, 29. The circuit can receive vision-sound " V.S. " or " S.V. " standards and the rejector circuits Rej 1, 2, 3 or 4 remove the unwanted sound and vision signals of adjacent channels from the output of the I.F. stage. When the rejector circuits are used in the vision branch of the receiver one of the rejector circuits is arranged to remove the sound carrier of the transmission being received. Rejector Rej 2 is fixed and consists of a series tuned circuit. The output from the last I.F. amplifier A3 passes to a detector stage D having diodes 22, 23, one of which conducts depending upon the voltage applied at 31, 32 by the standard changing switch so as to enable positive and negative modulation to be received. A.G.C. can be applied to the I.F. amplifiers A1, A2 at 30. The sound carrier may be A.M. or may be F.M., in which case the intercarrier signal is used to separate the vision and sound signals. When using the receiver on U.H.F. a filter 8 is provided between the U.H.F. converter 7 and the V.H.F. converter 3 to eliminate frequencies in the range 28-31À15 Mc/s.

Fuel, e.g. oil, is delivered under pressure via control pipe 56 to radial passages 68, Fig. 4, to flow into an annular passage 60 for atomization by pressurized air delivered through pipe 57, the fuel/air mixture passing through swirl grooves 74, formed on the outer surface of a nozzle part 67 or on the inner surface 77 of a nozzle part 66, to flow over surface 78 of part 66 to form the fuel rich core stream 98 which is generally hyperbolically shaped adjacent the nozzle 55. A minor portion of the air delivered by a fan (22), Fig. 1 (not shown), to a plenum chamber (23) flows via a tube 86 and pipe 58 to form a tertiary air sheath 99 around the core stream, the major part of the air from the fan flowing via an adjustable damper 34, comprising apertures in a casing 40 and apertures in a rotatable member 41, and flow straightening cores 51 to flow mainly through an annular gap 95 between a combustion chamber inlet member 94 and a bafflle 36 to form an outer air sheath 100, a small air flow passing through a mesh disc 90 of the baffle and through spaced vanes 92 aligned generally tangentially to the periphery of disc 90 to prevent back-flow of the core stream 98. The stratification of the air provided by the outer air sheath 100 and tertiary air layer 99 about the core-stream 98 results in burning of the stream 98 adjacent the nozzle 55 as a fuel rich mixture substantially isolated from the sheath 100, progressive mixing of the stream 98 and sheath 100 further downstream to obtain substantially complete combustion, whereby the burning is cooler than if complete mixing and combustion had not been delayed, in particular the combustion temperature is kept below about 2500‹F thereby reducing formation of nitrogen oxides, carbon monoxide, carbonaceous particulates and unburned hydrocarbons in the exhaust gases. The damper 34 may be adjusted automatically in response to conditions in the combustion chamber 33.
