46 FLIGHT 8 JULY 1960 MOVING COIL VIBRATOR TYPE V1000C . This vibrator has been developed to fill in the need for a medium power vibrator with a table surface in place of the usual single point drive spigot. The table is cast from a high duty magnesium and is 6in. (15.2cms) in diameter and provided with 12 X fin. B.S.F. tapped holes for attachment V" of the test object. The moving coil is ; attached directly to the table casting. The weight of the moving system is 17.6 lbs. (8 Kgs.), and a bare table acceleration of 31 'G' peak can be obtained for an input current of 10 amps., which is equal to a thrust of 550 lbs. peak for an input power of 1 KW. The vibrator can also be supplied with a blower (V.1000C.B) and will deliver a thrust of 750 lbs. peak for an input power of 2 KW. Can be trunnion mounted if required. W.

Top right is type K, a highly efficient filter consisting of a number of specially prepared paper discs compressed by springs and mounted on metal rods. Fuel passes through the minute interstices between the discs leaving solid impurities at the edges. Any water present causes the paper to Swell, with a consequent increase of back pressure, which gives an indication that servicing is needed. Bottom left is the Fuel Monitor, designed in conjunction with the Shell Petroleum Company Ltd. This is a fully "fail-safe" device, consisting of a valve and a water sensitive element, con- tinuously sampling the flow of fuel and causing the main valve to close if water contaminated fuel is revealed. . Bottom right is the high-output MC filter, giving what is for many purposes an acceptable filtration efficiency at a much higher rate than the K type. NEW THREE STAGE FILTER. Stream-Line Filters Ltd., have recently developed a three-stage filter/water separator which uses pleated elements made from paper, flbreglass and nylon to remove from aviation fuels all solid impurities and all water, in whatever proportions they may arise.
