Abstract: 639,483. Generating combustion products under pressure. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Jan. 2, 1948, Nos. 209 and 5254. Divided out of 639,468. [Class 51 (i)] [Also in Group II] In a combustion system for gas turbines, using pulverulent solid fuel or heavy fuel oil, the flame is stabilized by a recirculation of hot gases to the root of the flame and the combustion is continued in an annular or circular vortex chamber having an axially-directed outlet and in which the air is given a vortex flow about the axis of the chamber. In Fig. 1, the flame tube is open to the centre of the chamber 4. The main air stream passes from the common duct 24, through swirl vanes 28, between walls 4d, 4e, and enters the chamber 4 between guide vanes 19a. Some of the air passes the vanes 19a and is conveyed by duct 17a and swirl vanes 8a to the outlet stream. Air also passes between walls 25, 26 and swirl vanes 25a. The flame tube is provided with an air-blast burner 23 and a stabilizing cup 27a. Air is admitted to the cup through swirl vanes 23a and perforations 27a. Fig. 4 shows a similar arrangement provided with a rotary disc or cup atomizer 15 rotating on a spindle 16 either with or oppositely to the vortical movement. The atomizer 15 may be located in an up-steam cylindrical extension 36, Fig. 6, of the combustion chamber throat. An annular air-stream outside the swirl vanes 18a may be provided to prevent the deposit of fuel particles on the wall of the throat. Particles larger than desired may be eliminated from the fuel-carrying stream by sending the stream through a preliminary vortex chamber with an axial outlet through which only particles of the desired size will be carried. Ash particles may be extracted from the stream of combustion products by skimming off the outside layer of the whirling stream or by putting the stream through a centrifugal separator of the vortex type. In the form shown in Fig. 9, the whirling stream enters a chamber 45 at 47 and is discharged through an outlet 46 of the same diameter. The whirling motion in the chamber is maintained by extra air entering through vanes 48. Specifications 338,108, [Class 51 (i)], 636,624 and 639,468 are referred to.

Title: Improvements relating to travelling wave apparatus
IPC: H01J23/26
Filed: 1954-01-06
Abstract: 754,436. Helical lines. GENERAL ELECTRIC CO. Jan. 6, 1954 [Jan. 7, 1953], No. 393/54. Class 40 (8). [Also in Group XL (a)] Travelling wave apparatus comprises a travelling wave tube having two or more interleaved helices 4, 5, Fig. 1, the turns of which are insulated from another but the ends of which are connected together for D.C. and being coupled to a common source of signals, preferably by means of a common terminal ring 1 or cylinder, Figs. 5, 6 (not shown), so that they are excited substantially in phase with one another, the helices being wound in the same direction and having the same pitch and diameter. In Fig. 1, two helices of the same pitch and diameter are connected in parallel between metal terminal rings 1, 2. Input and output coaxial lines have their outer conductors connected to shield 7, which may or may not be part of the tube envelope, and their inner conductors connected to rings 1, 2. The helix arrangement may be grounded by means of a #/4 stub 17. To ensure that the waves on the two helices are in phase the helices are welded to each ring 1, 2 at a common point displaced 90 degrees from the inner conductor of the input or output line. For more than two helices exact in phase working is not possible but if the helix and coupling ring circumference is small compared to # a sufficient approximation is achieved. If there are four helices in parallel their ends are connected to the rings at equal intervals around their circumference and the coupling connection is made half way between two helix junctions, Fig. 3 (not shown). Alternatively, as shown in Fig. 4, four helices 24, 25, 26, 27 are secured at equal intervals to terminal ring 30 sealed to tube envelope 31 and to collector 32 via glass ring 33. A TEM wave is excited in output concentric line 35, 36 coupled to the concentric structure 34, 24 by tapered sleeves. The collector lead 37 passes through the hollow inner conductor 36 and out through the; hollow inner conductor 39 of a #/4 stub. A similar arrangement is provided at the input end of the tube for feeding in a TEM wave to a second terminal ring and for supplying D.C. potentials to the gun. If rings 1, 2, Fig. 1, are replaced by cylinders capacitative coupling can be had with external coaxial lines or waveguides, Figs. 5, 6 (not shown). There may be two helices in parallel, or more if the circumference of the coupling cylinder is small compared to the wavelength. In another embodiment, Fig. 7 (not shown), two helices are coupled to separate coaxial lines diametrically opposite one another by welding them to the inner conductors of the lines. The lengths of the lines are such that signals are fed in or out in the same phase, and the lines are coupled to a common signal source.
