Which of the following most accurately describes the problem?

WE RECENTLY -attended a demonstration of the new centrifugal filter which can now be utilized on the well-known BOINSCr petrol pumps forming part of the popular equipment for the storage of petrol in bulk, and its delivery in accurate quantities as desired, and marketed by S. F. Bowser and Co. {Inc.), Windsor House, Victoria Street, London, &WA.

The use of this filter affords an assurance that 'petrol will be discharged from the pump free from water ancl''dirt and solid impurities. The chief advantage of its use Is that the filtering is quite automatic, and performed while the petrol is being pumped through the delivery pipe in the ordinary manner. The filter consists of an iron core with a spiral fin or rib east in one with it and forming a fairly close fit between the core and the outside of the filter chamber. At the lower part of this core isia gauze filter of fairly fine mesh.

Petrol enters the filter at the top and is forced downwards by the pressure of the pump.. In its journey it has to tra verse the spirals at some speed. In doing sr), the centrifugal action throws

the foreign matter, such as water and dirt, to the exterior, whilst the compare,,tiveiy light petrol remains nearer the centre of the filter and is eventually forced through the gauze screens, leaving the water and dirt behind.

The filter requires cleaning out every few days, but this is a very simple operation. It is effected by closing the pump nozzle, opening the valve at the top of the filter and working the pump elowly. At the beginning of this pro reduce, a slight quantity of petrol will be discharged before any water appears. By letting this flow into a glass, it will easily be seen when the water is being passed, as the petrol will rise to the top of the water, giving a distinct line of separation. The operaton is continued until all the water is forced out and petrol again appears, after which the filter valve is closed.

To show the very efficient working of the apparatus, red-coloured water and petrol were mixed together iii a glass tank, from which aBowser pump drew it: supply. For the purpose of the clemonstration, the water draw-off on the filter was extended so that any water filtered out was returned to the tank, whilst the petrol was also returned to the tank, after being pumped through.

It was most interesting to observe the way in which every drop of coloured water was separated out directly the pump was operated, whilst perfectly clear petrol was discharged from the proper nozzle. The slightest trace of water would have shown up at once, and as this did not appear, the efficiency of the filter was certainly proved,
