Title: Method and apparatus for minimizing the nitrogen oxide content of exhaust gases from combustion power plant
IPC: F02M25/00
Filed: 1972-06-20
Abstract: 1381747 Treating I C engine charge; gas turbine plant NISSAN MOTOR CO Ltd 20 June 1972 [22 Nov 1971 25 Nov 1971] 28747/72 Headings FIB and F1G [Also in Division F4] Air passed through a nitrogen separator 26 is mixed with exhaust gas from an engine 10 or a gas turbine and the resulting mixture has fuel added to produce a combustible mixture. The separator 26 has a nitrogen adsorber 30, e.g. zeolite particles, or a nitrogen impermeable membrane and the quantity of recirculated exhaust gas is controlled by a valve 40 to provide an oxygen to exhaust gas ratio substantially corresponding to the oxygen to nitrogen ratio of atmospheric air.  For heavy load operation of the engine, air under the control of a valve 52 is mixed with the dinitrified air and exhaust gas. The nitrogen is removed from the separator 26 by a suction pump 48 and discharged to atmosphere. A pair of nitrogen separators (26a, 26b), Fig. 2 (not shown), may be alternately connected one to the engine intake manifold via the carburetter 14 and the other to the suction pump 48. The inlet passages (28a, 28b) of the separators (26a, 26b) may contain moisture and carbon monoxide absorbent, e.g. silica gel and zeolite particles, (58a, 58b, 60a, 60b) downstream of the connections of the suction pump 48 to the inlet passages. The valves controlling the flow of air into the separators and the connection of the suction pump to the separators and the valves 50 and 52 may be operated by computer control unit (66), Fig. 2 (not shown), in accordance with the engine operating conditions. The separators may be formed by a rotary drum (88), Figs. 4 and 5 (not shown), within a stationary drum (78). The rotary drum (88) is divided by partitions (96, 96', 96") into compartments, each containing nitrogen and water and/or carbon monoxide separating material, which are brought successively into communication with flow passages to the engine and the suction pump as the drum is rotated by the engine.

Abstract: 958,681. Transformers. SPERRY GYROSCOPE CO. Ltd. Aug. 19, 1960 [Aug. 21, 1959], No. 28748/59. Heading H1T. [Also in Division H2] Fig. 1 shows an angular position responsive device, comprising a stator 1 and unwound rotor 13 with skewed poles 17, 18, arranged for relative rotation in bearings 15 and 16 of casing assembly 19, 20, the twelve slot stator having primary winding S1, S2 (Fig. 3), and a secondary winding S3, S4 with their axis mutually at right-angles. The primary winding S1 S2 having the lesser extent around the stator, is energized to produce an exciting flux through the rotor 13. As the rotor is rotated, relative to the stator, the flux linking with the windings S3, S4, charges and causes an e.m.f. to be induced in this winding, which, over a limited range, varies approximately linearly with the angular position of the rotor. The skewed poles 17, 18 (Fig. 4), of the rotor 13, extend over an angle corresponding to that between a number of stator slots, thus causing the output of the stator winding S3, S4 to vary smoothly.

Abstract: 924,998. Crimping yarns and fibres. JOSEPH BANDCROFT & SONS CO. Aug. 19, 1960 [Sept. 23, 1959], No. 28808/60. Class 120 (3). A stuffer crimper comprises rolls feeding fibres into one end of an elongated chamber and forcing the mass of crimped fibres therealong to a discharge point, and a control wheel the periphery of which projects into the chamber, e.g. adjacent the bite of the rolls. The wheel and rolls are driven at a predetermined speed ratio so as to control the back pressure in the zone therebetween. As shown in Figs. 1 and 2, rolls 10 and 11 are loaded by a spring 16 to grip tow or yarn 20 and feed it into the chamber formed by a tube 4, the entry end of which is shaped to the contour of the feed rolls. Control wheels 30, 31, having smooth, serrated or toothed surfaces, and the former retractable against a spring 36, restrict the feed of the fibrous mass in the tube so as to control the feed in the zone between wheels 30, 31, and the nip of rolls 10, 11. The pressure in this zone may be higher or lower than the pressure in the setting zone wherein heat is applied through a block 2 by heating rods 54 and the pressure is determined by the relative speeds of wheels 30, 31 and delivery rolls 52 and by the weight of a plug 50. The rolls 10, 11, are driven from a pulley 23 through intermeshing gears 21 and 22, shafts 12 and 13 and constant torque mechanical or magnetic clutches as at 24a. The wheels 30, 31 are driven from shaft 12 by a worm 40, worm-wheel 41, pinion 42, idler shaft 43, gear 44 on shaft 33 and intermeshing gears 37.
