Abstract: 1,233,604. Endoscopes. OLYMPUS OPTICAL CO. Ltd. 7 Aug., 1968 [8 Aug., 1967 (4); 29 Aug., 1967], No. 37687/68. Heading A5R. [Also in Division G2] An endoscope suitable for measuring the distance of an object from the forward end portion of the endoscope comprises a control housing (2) connected to the forward end portion (1) by a tube 3, there being an optical system for transmitting an image of an object from theforward end portion to an eyepiece (5) in the control housing, and there being means 15 in the forward end portion for projecting a thin parallel light beam so as to form a light spot on the surface of the object inspected through the endoscope, an indicator being provided in the control housing for determining the position of the light spot with respect to the field of view inspected through the endoscope so that the distance of the object from the forward end portion of the endoscope can be measured. As shown, an object 10 illuminated by a lamp 12 is inspected through a lens system 8, 9 and a light conducting fibre system 7. A light source 13 (a lamp or light conducting fibre system) provides a light spot on the object 10 which may be related to the graduated field of view (Figure 3, not shown) seen in the eyepiece such that the object distance can be determined. In modifications a movable graduation (18) may be provided (Figures 4, 5, not shown), and the required movement to effect alignment is noted, or the direction in which the light beam is projected may be adjusted and the necessary adjustment for alignment between the light spot and a fixed graduation is noted. In alternative embodiments (Figures 6, 7, not shown) two thin light beams are projected from light sources (15,21 or 23,24) in the end portion of the endoscope and the distance of the object from the endoscope is determined on consideration of the separation of the two light spots in the field of view, or of the adjustment necessary in order to bring the spots into coincidence. Measuring the field of view. Since the field of view available to the endsoscope is dependant on the magnification of the lens system and the distance of the object from the end portion of the endoscope, the endoscope may include a differentiating mechanism whereby the actual dimension of the field of view may be determined, the differentiating mechanism being coupled to the magnification vary means (not otherwise described) of the endoscope and to either the focus adjustment of the objective lens system or to the distance measuring device. The differentiating mechanism comprises either inter-related gear racks (Figure 18, not shown), planet-gearing (Figure 19, not shown), or an arrangement of levers (Figure 20, not shown). Measuring the size of an object. The endoscope may be arranged so that the actual size of an object may be measured by coupling a sizing device to the differentiating mechanism in place of the coupling to the magnification varying means. Suitable sizing devices for aligning with the image of the object comprise (Figures 23-25, not shown) pivoted blades, . an iris diaphragm, or relatively movable frame parts.

Abstract: 1,265,080. Iron oxide; regenerating HCl. NATIONAL LEAD CO. 4 July, 1969 [12 July, 1968], No. 33945/69. Heading C1A. In a process for regenerating HC1 from a solution of iron values, the iron values are dissolved in an aqueous solution of HCl and FeCl 2 , and the resulting aqueous FeCl 2  solution is divided into two portions. One portion, containing substantially the same amount of FeCl 2  as was present in the original HCl-FeCl 2  solution, is fed to an absorber. The other portion is roasted, e.g. at 400-455‹ C. to recover particulate Fe 2 O 3  and HCl gas, which latter is fed to the absorber where it contacts the said one portion of FeCl 2  solution, forming a condensate comprising an aqueous HCl-FeCl 2  solution which is then recycled to dissolve further iron values. This solution may contain 7-20% by wt. HCl and 17-32% FeCl 2 . Losses in HCl may be made up by addition of fresh acid to the condensate from the absorber. The higher the concentration of FeCl 2  added to the initial solution, the lower the proportion of water is there in that portion of the FeCl 2  solution fed to the roaster. In examples, the iron values are leached from titaniferous ores, or derived from steel in a pickling process.
