Patent GB-971806-A (GB)
Abstract: 971,806. Gas turbine jet propulsion plant. K. LINK. Dec. 18, 1961, No. 45263/61. Headings FIG, F1J and F1T. A jet propulsion engine comprising an air compressor driven by a gas turbine, has a first group of combustion chambers for gases flowing continuously to the turbine and a second group for heating the gases flowing directly to thrust nozzles and has a heat exchanger for pre-heating the compressed combustion air by the exhaust gases of the turbine, the parts of the turbine and/or thrust nozzles contacting the hot exhaust gases being provided with fireproof lining, which exchanger is constructed as an adjustable air distributer, the cross-sectional flow area of which remains unchanged for the air supply to the first combustion chamber group on adjustment of the cross-sectional flow area, between the limits of cut-off and complete opening, for the air supply to the second combustion chamber group. Air supplied by a compressor 2, Fig. 1, is heated by a heat exchanger/air distributer 3, Figs. 1 and 3, and flows through a port 16 in the latter to combustion chambers 6. The combustion products pass to a fireproof lined distribution chamber 9 of a turbine wheel 10 where they are ejected through fireproof lined nozzles 11, Figs. 1 and 5, to drive the turbine. The ejected gases heat a wall 7 of the heat exchanger/air distributer 3 provided with ribs 8, 8a, before providing a thrust through an outlet 5 provided with steps 14 for silencing purposes. A slide valve 15 is adjustable to regulate the position of depressions 18, in communication with the air supply, with respect to radial ports 19 within the limits of cut-off and complete opening without altering the cross-sectional flow area to the chambers 6. The ports 19 communicate with combustion chambers 6a the products of combustion from which flow through a fixed fireproof lined chamber 12 and fireproof lined thrust nozzles 13 to the outlet 5 where they heat the turbine exhaust gases. Three cam discs may be provided on a rotatable shaft, each cam controlling respectively the position of the valve 15 and the fuel supply to the chambers 6 and 6a. The cams may be designed so as to provide maximum fuel economy or maximum thrust and may be individually regulatable. Turbulence, created at the openings 16, 18, 19, improves the heat transference of the exchanger/distributer 3 at the directly adjacent surfaces, and the openings 18 may be arranged to continue this effect even when the ports 19 are closed. The number and dimensions of the nozzles 11 are preferably chosen so that the pressures in the combustion chambers and the distribution chamber at least approach the compressor pressure.

IPC: C03B3/02
Filed: 1998-10-20
Abstract: Apparatus for contacting gases with solid particles comprises a discharge electrode 3, a collector electrode 1, 2 and a bed of particles 34 moving between the electrodes. A voltage applied across the electrodes is varied between a high voltage, sufficient to cause corona discharge thereby charging the particles and causing them to move towards the collection electrode, and a low voltage which causes the particles to move away from the collection electrode. This reciprocating particle motion enhance the gas to solid contact. The apparatus can be adapted for use in heat transfer (106, Fig. 12), mass transfer, chemical reaction, drying, dehydration, adsorption and calcining. In particular it can be used for treating flue gases, e.g. from a glass making furnace (Fig. 15), when the particles provide a surface for adsorption/reaction of pollutant gases and an electrostatic precipitation surface for removing pollutant particulate matter.

Title: Estimating accuracy of an automatic language translation
Inventor: BERNTH ARENDSE
IPC: G06F17/28
Filed: 1999-09-24
Abstract: A computer system and method for natural language translation uses a translation process to translate a source natural language segment (e.g. English) of one or more source words/elements into a target natural language (e.g. German) segment of one or more target words/elements. An evaluation module determines a confidence measure of the natural language translation, which indicates less confidence as the complexity of the translation increases. The translation process can be terminated if the confidence measure fails to meet a threshold criterion. The translation may involve parsing a segment into a parse structure which is converted via a transfer structure into a target structure, and the complexity of each of these stages may be used to determine the total complexity of the translation.
