Title: Method of calibrating scanning micro-analysers, and apparatus therefor
Inventor: MELFORD DAVID AUSTIN
IPC: G01N23/225
Filed: 1965-12-11
Abstract: 1,126,368. Calibrating scanning radiation analysers. T. I. (GROUP SERVICES) Ltd. March 8, 1967 [Dec. 11, 1965], No. 52706/65. Heading G1A. Scanning X-ray or electron micro-analyser is calibrated by causing the beam of a c.r.o. tube to scan the screen of the tube in a manner similar to that in which the beam of the microanalyser scans an area of a specimen when in normal use, providing an apertured mask which allows only selected parts of the image on the screen of the c.r.o. tube to be "viewed" by sensing means responsive to this image and producing a characteristic signal when the image is visible to it through the apertures in the mask, and causing the signals from the sensing means to control the movement of the beam of the microanalyser, so that it strikes a material of one chemical constitution when the sensing means "views" no image through the apertures in the mask, and causing it to strike a material of another chemical constitution when the sensing means does "view"an image through an aperture in the mask, and then adjusting the means for presenting the output of the analyser so that the output presented by it is consistent with that expected from the examination by the microanalyser of an area of a specimen of said one chemical constitution having inclusions of said other chemical constitution distributed over the area in the same way that the apertures are distributed over the mask. The micro-analyser of Specification 1,046,443 is modified in that the scanning signals for the micro-analyser generated by heads 21, 22 from a magnetic drum 20 are switchable selectively to the deflection coils 13 of the analyser for normal analysis or to the deflection plates 26 of a cathode-ray tube 27 for calibration. The screen of tube 27 is viewed by a photo-multiplier 30 through a brass mask 28 with holes simulating a predetermined pattern of inclusions in a test sample. The output of photomultiplier 30 switches the beam 11 of the analyser between different parts of a reference specimen according as the light from the tube 27 is or is not blocked by the mask 28. The output of the analyser is compared with a known value corresponding to the mask 28 and the circuits 15, 16 and 17 are adjusted until the values are equal.

Filed: 1972-11-22
Abstract: 1383097 Lowering pH of cooling water by electrolysis MAGNA CORP 22 Nov 1972 53965/72 Heading C7B The pH of recirculating cooling system water subject to evaporation and hence increasing salt concentration is lowered e.g. in a conduit 86 by flowing a stream of water past an anode e.g. in anodic branch 92 so that its pH is lowered below that of the cooling water, and adding the whole of this stream to the cooling water e.g. via return line 104, and flowing a separate stream of water past a cathode e.g. in cathodic branch 94 and discharging the whole of this stream. Both streams may be drawn via supply conduit 88 from a common source which may be the cooling water in primary conduit 86 or well (32), Fig.3, (not shown). The rate of flow of the first stream is preferably greater than that of the second stream and is controlled by valves 100, 102 and pump 90 via switch 112 and controller 108 in dependance upon the pH of downstream cooling water sensed at 106; the voltage source 96 to the electrodes may be similarly controlled via switch 110. The electrodes may be annular or of recticulated, perforated sheets, Fig.2 (not shown) or otherwise formed of closely spaced electrically connected elements, the anode being of C (graphite), Pt or Ti, the cathode of brass, Ni or steel or the same material as the anode. Corrosion inhibitors e.g. sodium chromate or polyphosphate may be added to the water. The voltage may be half-wave rectified or other fluctuating (direct) current)
