Patent GB-980427-A (GB)
Title: Improvements in or relating to heating ferrous oxide
IPC: C01G49/04
Filed: 1961-03-27
Abstract: As a preparatory step to the production of pure iron powder by reduction of ferrous oxide with hydrogen, the ferrous oxide is preheated to 600-800 DEG  C. in two fluidized bed stages, in the first of which its temperature is raised to about 100 DEG  C. by means of a fluidizing moisture-free gas consisting of carbon dioxide, nitrogen or mixtures thereof and in the second stage the hot oxide is passed to a series of fluidized beds through which it passes in an overall countercurrent direction to a gas consisting of carbon monoxide, carbon dioxide, nitrogen, hydrogen and steam which enters at 850 DEG  C. and which has an overall composition such that it is in equilibrium with FeO at temperatures above 550 DEG  C.  The second gas stream is suitably obtained by the incomplete combustion of methane.  As shown in Fig. 1, ferrous oxide is fed from a hopper 3 to a fluidized bed 4 through which a carbon dioxide/nitrogen stream passes upwardly to be recirculated through a heat exchanger 7.  The ferrous oxide, now at 100 DEG  C., is fed through a conveyer 8 to a plurality of successive fluidized beds 10.  Hot gases obtained by the partial combustion of methane in burner 11 pass upwardly and fluidize the successive beds and are withdrawn through a fan 14 and passed in part through line 15 and the tubes 19 of a heat exchanger back through line 21 to the bottom of the second heating zone, and in part through line 16 where, at the foot of the heat <PICT:0980427/C1/1> exchanger 17 they are burnt with oxygen to heat the tubular heat exchanger 19.  The ferrous oxide powder then passes from the lowermost fluidized bed through a gas-tight conveyer 22 to the apparatus where it is reduced with hydrogen to iron powder.  The conveyers 8 and 22 linking the first and second heating stages and the heating and reducing stages respectively are preferably gas tight and differential pressure gauges may be placed thereacross. Responsive to such a gauge, the pressure in one or other of the stages may be adjusted to prevent gas leak between stages. Specifications 980,425 and 980,426 are referred to.

Title: Improvements in monochromators and like spectroscopic apparatus adapted for double dispersion
IPC: G01J3/16
Filed: 1931-04-15
Abstract: 362,305. Spectroscopic monochromators. MILLER, C., 86, Soorstrasse, Charlottenburg, Berlin. April 15, 1931, No. 11181. [Class 97 (i).] A double monochromator comprises two sets of spectrum-producing parts with auto-collimation and with chromatically uncorrected imaging systems, so combined about an intermediate slit that light passes through the slit out of one set of parts into the other, a common means of wave-length adjustment being provided for the two sets of parts. The spectrum-producing parts shown comprise half prisms 12, 13 each having one refracting and one reflecting surface, and collimating lenses 14, 15, disposed on opposite sides of a slit carrier 2 having slits 3, 4, 5 in vertical alignment. The lenses and prisms are mounted on sliders 6, 7 which can be displaced simultaneously by a right-and-left handed screw 9, 10 operated by a drum 11 carrying a scale of wave-lengths. The prisms 12, 13 are mounted on pillars 27, 28 rotatably mounted on the sliders, these pillars being provided with arms 16, 17 which are spring-urged into contact with fixed pins 18, 19, so that rotation of the prisms is automatically produced when the sliders are displaced, to set the prisms for minimum deviation of the wave-length being used. The incident light is reflected by a prism 22 so as to pass through the slit 3 to be collimated by the lens 14, and is then dispersed by the prism 12 to be focused by the lens 14 as a horizontal spectrum across the slit 4. A narrow band, the wave-length of which is determined by setting the drum 11, passes through the slit and is received by the parts 15, 13 which effect purification of the light, monochromatic light being focused on the slit 5 and directed out of the apparatus by a reflecting-prism 23. The slits may be arranged side by side on the holder 2, or they may be arranged in different transverse planes on three separate holders. By turning the prism 13 so that its refracting edge is towards the rear instead of towards the front as shown, the system 15, 13 can be made to double the dispersion instead of purifying. The same effect can be produced without moving the prism 13, by providing a reversing prism adjacent the slit 4.
