Abstract: 935,903. Generating combustion products under pressure. V. H. PAVLECKA. Sept. 7, 1959 [Sept. 8, 1958], No. 30536/59. Class 51 (1). [Also in Group XXVI] A gas turbine power plant comprising centripetal flow compressor stages, centrifugal flow turbine stages and a combustion chamber arranged for air to flow inwards through all the compression stages to the combustion chamber and the combustion products flow outwards through all the turbine stages, has at least two rotors rotating in opposite directions and each rotor comprises at least two of the compression stages as well as at least one of the turbine stages. The gas turbine plant shown, Fig. 1, comprises a frame 10, a first rotor 12, a second contra-rotating rotor 13 and a toroidal combustion chamber 14 which constitutes an integral part of the inner rotor 13. The four-stage centripetal compressor has stages 16, 18 attached to the rotor 12 and stages 17, 19 to the rotor 13. The rotor 12 is driven by turbine stages 23, 25 and the rotor 13 by turbine stages 22, 24. Some of the air leaving the compressor is conveyed to a machine such as a load turbine through a duct 145 containing flow directing vanes 146. The remainder of the air flows is indicated by the arrows 130, 148, 149, 150, 151, 152, 153, 154, 155. The flows 153, 154, 155 passes through slots 160, 161, 162, to ducts 165. The flows 148, 152 pass direct to the intake of the turbine where they mix with the combustion products 166 from the combusion chamber. This air protects the wall 68 from the heat of the gases. The air flow 151 is used in air bearings. The portion of the compressed air that enters the combustion chamber is shown by the arrows 130, 150. Fuel is introduced into the stream 130 by means of nozzles 174 and ignited by means of a ring 181 which is insulated from the duct 145 and to which a low frequency voltage superimposed by a high frequency voltage is applied. The partially burnt gases leaving the duct 126 are mixed with air from the ducts 165. The combustion products pass through the ducts 166 to the turbine. Cooling air passes through ports 132 and passes around the combustion chamber to mix with the combustion products leaving the chamber. Cooling air also passes through ports 71 and blades 22. A number of modifications of the plant are described; some have stationary combustion chambers and some more than two rotors. The design of combustion chamber may be varied. In one modification the combustion chamber has two vortices and in another the fuel is supplied through a radial arm where it is mixed with air and then discharged through a snail-like formation at the end of the arm arranged on the axis of the toroidal combustion chamber. Specifications 743,475, 847,359, 877,987 and 877,988 are referred to.

Abstract: 1,039,137. Particle accelerators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 4, 1964 [July 29, 1963], No. 30675/64. Heading H1D. A particle accelerator employing cyclotron resonance acceleration has a curved, as shown annular, gap 19 across which the particles are simultaneously accelerated in many different orbital paths by an R.F. electric field applied between the hollow electrodes 9, 10 bounding the gap. The particles attain maximum orbits 26 which are caused to precess around the vacuum chamber due to a weakening of the transverse magnetic field at the periphery due to flux leakage. The magnetic polepieces on either side of the vacuum chamber are tapered to keep the flux density approximately constant across the poles. The accelerated particles are diverted to the outside of the chamber by deflecting electrode 20. The frequency of the applied R.F. field may be equal to the cyclotron frequency of the particles, but preferably the third harmonic is chosen. The ion source is shown at 11 and additional ions may be produced by impact with hydrogen gas in the chamber. The electrodes are water-cooled. Coaxial feed lines 22 for the R.F. pass through the polepieces and are connected to the centres of the electrodes 9. The structural frame of the accelerator chamber may be formed of stainless steel, brass, copper-alloy, or bronze plates or castings. The chamber lids are of soft iron.
