Abstract: 612,746. Water-tube steam boilers. BABCOCK & WILCOX, Ltd. May 31, 1946, No 16590. Convention date, June 2, 1945. [Class 123(ii)] In a water-tube steam boiler comprising a furnace chamber 17, Fig. 4, which extends from a front wall 10 fitted with burners 19 to a rear wall 12, and a passage 18 which is separated from said furnace by a partition 16, terminating short of the rear wall 12 to provide an entrance 21 thereto, and locates steam-generating tubes 25, a baffle 45 is fitted at the end of the partition to obtain a more uniform gas flow through the entrance 21. Both the partition and baffle preferably comprise a plurality of closely-spaced tubes 25a, 45a respectively and the baffle makes an angle of at least 90 degrees with said partition. In one modification, this angle is 150 degrees, and in a further construction the baffle is in the form of a series of narrow baffles 41, each comprising three water tubes 41X, 41Y, 41Z, Fig. 2, which extend transversely into the furnace in mutually-stepped relationship from adjacent the end of the partition to a location spaced from the entrance 21 and adjacent the wall 12. The steam generating tubes 25 and the tubes lining the boiler walls 10, 12, 13, 14, also the tubes of the partition 16 and baffle 45, extend between an upper steam-and-water drum, not shown, and a lower water drum 24, and the tube bank 25 is traversed by baffles 28, 29 which divide the passage 18 into three serially connected passes 31, 32, 34, the last pass being provided with a gas outlet. The tubes 25c of the bank 25 within the passes 32, 34 are of lesser diameter and less widely spaced than the corresponding tubes 25b in the pass 31 which are arranged in two spaced groups to accommodate an intermediate superheater 36 comprising inlet and outlet headers 37, 38 connected by looped tubes 36a, and the tubes 25b on the inlet side of the superheater are preferably spaced as shown. Specification 496,488 is referred to.

Title: Improvements in or relating to microanalysers
IPC: G01N23/225
Filed: 1964-04-23
Abstract: 1,030,042. Television. COMPAGNIE D' APPLICATIONS MECANIQUES A L'ELECTRONIQUE AU CINEMA ET A L'ATOMISTIQUE (C.A.M.E.C.A.). April 23, 1964 [April 25, 1963], No. 16969/64. Heading H4F In a microanalyser-spectrometer arrangement for scanning the surface of a crystal, the specimen 41 (Fig. 4) upon being struck by an electron beam along Oz emits radiation, e.g. X-rays towards a crystal analyser 49 which radiation is reflected towards the slit 410 of the detector, the scanning system comprising first means 48 for deflecting the electron beam along a first axis, e.g. Ox, for which the apparent sensitivity of the spectometer is not substantially affected by this deflection, and second means 43 for displacing the specimen along a second axis, e.g. Oy which intersect the first axis and which is contained in the plane of the specimen. The first means comprise a pair of parallel deflecting plates 48 fed from a sawtooth source 51 (Fig. 5). This produces scanning by the electron beam substantially along the Ox axis which results in the X-rays produced being incident on a crystal analyzer 49 at substantially equal angles. The variation in the apparent sensitivity, i.e. the ratio of the detected X-ray intensity to the intensity emitted by the sample, is thus found to be negligible for scan displacements along the Ox axis, although such displacements along the Oy axis would be important. Since the angles of incidence at the analyser vary, very small angular departures of the scan direction from the Ox axis may also be allowed. A mechanical system is therefore used to displace the sample itself and produce a scan along the Oy axis. The system involves supplying a saw-tooth voltage to a coil 46, which is located in the air gap of a permanent magnet 47. The coil oscillates carrying with it one of the flexible blades 43 on which are supported the specimen 41. X-rays reflected from the crystal 49 and focused at the slit 410 of a detector 58 (Fig. 5) which is, for example, a proportional or scintillation counter. The screen of a cathode-ray tube 514 is scanned in synchronism with the scanning of the specimen, the brightness of the spot on the screen being modulated by the intensity of the detected spectral line. This enables an image of the scanned area to be obtained for the particular radiation wavelength to be considered. The saw-tooth voltage from source 51 is amplified at 52 and the secondaries 511, 512 of a transformer 510 feed the plates 48 and the vertical deflection plates 513 of the C.R.T. respectively. The saw-tooth voltage for the coil 46 is produced by modulating a sinusoidal source 53 by a linear variometer 54 and the signal is amplified at 55. The outputs of the transformer 515 are applied through detector circuits to the coil 46 and the plates 530 of the C.R.T.
