Filed: 1930-10-31
Abstract: 366,522. Spray carburetters. HENDERSON, J. G., 17A, Belsize Avenue, Hampstead, London. Oct. 31, 1930, No. 32775. [Class 7 (iii).] Rich mixture. formed in a jet tube 23 by admitting air to a fuel well 11 into which the lower end of the tube dips when the level is normal, is admitted by a passage 27, Fig. 4, to the throat of a venturishaped main air passage adjacent to the throttle valve 16. All the air supplied to the carburetter passes through a perforated plate 14 the size of the orifices 13 being such that D = Á/#Hp where D = ratio of the size of an air orifice to that of a geometrically similar submerged fuel jet 12, H = the ratio of the fall of pressure at the choke formed by the plate 14 to that at the fuel jet, Á is the ratio of the viscosity of the air to that of the fuel, and p = ratio of the densities of the air and fuel. By this means the Reynolds Number for the flow of air through an air orifice 13 is made equal to that for the simultaneous flow of fuel through the fuel jet 12. The number N of orifices 13 required to ensure a final mixture having a ratio R of fuel to air by weight is determined by the formula, N = R/DÁ. Air for forming the rich mixture is admitted by a slot 20 to an adjustable opening in a plug 19 located in a duct communicating with the fuel well 11 ; the latter serves as a guide for the float. An adjustable shutter 40 may be moved manually over the plate 14 to vary the proportion of air in final mixture ; the shutter control lever 39 may be actuated conjointly with the throttle control to cut off a portion of the air supply at the maximum throttle opening. A baffle 36 protects the air inlet plate 14. The float chamber is secured by a single bolt positioned diametrically opposite a locating pin 9 which engages projections 10 formed on the chamber.

Title: Improvements in heat exchange apparatus for fluids
IPC: F28D7/06

Abstract: 640,680. Tubular heat-exchangers for heating feedwater &c. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 17, 1947, No. 33314. Convention date, Oct. 8, 1943. [Classes 64(i) and 64(iii)] The invention relates to a heat exchanger for fluids, one of which is condensible, and apparatus is described for heating boiler feedwater by means of steam taken from the intermediate stages of a turbine. The water to be heated passes through a chest 3 by way of an inlet 4 and an outlet 5. Intermediately the water passes through a tubular system 10 in a lower unit 2 where it is heated by the condensate from an upper unit 1 containing a tubular system 7 in to which it next passes by way of a pipe 12 in the chest to condense steam entering from an inlet 6. The condensate drains from the upper to the lower unit by a pipe 9. The steam inlet 6 and the condensate pipe 9 communicate with cylindrical baffles 13, 14, arranged coaxially in the upper and lower units respectively so that the heating fluid flows outwardly from the chest along the middle of the units and then inwardly along the outsides of the baffles. The heat exchange units 1, 2 may comprise U-tubes arranged so that their limbs lie in planes which are radial to the common axis of the units and baffles as shown or in a modification (not shown) the limbs of the U-tubes may be arranged in parallel planes and astride a plane baffle, in which case the heating fluid in each unit passes up one side of the baffle and then down the other side. A battery of the heat exchangers may be interconnected by flanges on the water pipes 4, 5.

Abstract: 869,809. Radar. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. March 22, 1960 [Oct. 5,1959], No. 33626/59. Addition to 869,808. Class 40(7) The adjustment of phase shifter 11 which is effected automatically under the control of an amplitude sensitive device to bring the output of mixer circuit 8 to zero and thereby indicate the range of the reflecting object in the frequency modulated C.W. radar system described in the parent Specification is, in the present invention, effected under the control of a signal derived from a phase detector D in which the phase of the output signal from mixer 8 is compared with the phase of the output signal from a further mixer 88 in which the modulating signal from source 1 (or a harmonic thereof derived via device 9) is combined with the frequency range selected by filter amplifier 7. When the output from mixer 8 drops to zero the phase of the output signal from mixer 88 passes through 180 degrees and this permits a more precise adjustment of phase shifter 11 to be effected than the amplitude responsive device of the parent Specification allows. The phase detector D produces a D.C. output which may be employed in any manner to cause the motor control device 311 to adjust phase shifter 11 to maintain the output from mixer 8 at the point at which the 180 degrees phase change in the output of mixer 88 occurs. Alternatively a two-phase motor having one phase winding fed from mixer 8 and the other phase winding fed from the output of mixer 88 after phase shifting through 90 degrees may replace the phase detector D and the motor control unit 311. The inputs to the mixers 8 and 88 may be at the fundamental frequency of the system (i.e. the frequency of the modulating source 1) or one mixer may be supplied with the fundamental frequency and the other with a harmonic thereof or two different harmonic frequencies may be employed as described with reference to Fig. 3 (not shown).
