342 APRIL II, 1940 THE INDUSTRY (Right) A unit of the Metafilter showing the fluted rod and rings. Abattery of these units is enclosed in the complete filter shown above. Fit. »• Sylt RemoverW HILST Wing Commander W. E. Staton, with his bombers, has been busy doing his best to blow Sylt into the water, his brother, Mr. M. N. Staton, service manager of Metafiltration Co., Ltd., does his best to remove silt from the drinking and radiator water of the R.A.F. The Metafilter through which the water is pumped for clarification is made up of a number of filter packs. These take the form of fluted rods on which are threaded scalloped rings, the whole being enclosed in a casing of kieselguhr. The water is forced through the kieselguhr and then between the scalloped rings which have a clearance of only 0.003 in., and finally up the flutings on the centre rod to the main outlet at the top of the filter unit. A singles unit is capable of handling five hundred gallons per hour. A point of importance is their robust construction; no spares being needed other than supplies of kieselguhr to re- place used filter beds. Not Just Gas OM a national point of view everyone is asking the same ques- tion to-day, and everyone who dares to answer it is answering in the same way— some more eulogistically than others. We have traversed along the dark mile and we approach the gleam of the future. I am not a pessimist in peace or in war. When we look back over the last five years I am sure we all have a feeling to-day of power, strength, and security that was sadly missing in that period." The above quotation is from the speech by Col. S. J. L. Hardie, D.S.O., who presided at the annual general meet- ing of the British Oxygen Company on April 3. The financial state of the con- cern was shown to be immensely strong; consolidated profits of the organisation amounting to no less than £i,387,995. It was agreed to pay a final dividend of 10 per cent., less income tax, making a total of 17 per cent, for the year. At the extraordinary general meeting which followed, the resolution to distribute one ordinary share for every five held, by the capitalisation of a part of the undivided profits was also approved.
