Canadian engineer . - forzs utile - Potvi feet, each unit being designed for a maximum power of 6,, when running at a speed of 420 revolutions perminute. These turbines are all of the Escher Wyss Companysspecial design and patent, fitted with deflecting nozzle whicheliminates the employment of any relief valve, at the sametime keeping the rise of pressure in the penstock remarkablylow. As a matter of fact, when tests were made and the fullload was thrown off, the pressure at the end of the penstock. only rose to a very few per cent, above normal. The aboveefficiency which exceeds the guaranteed figures lay about8 per cent, is remarkable by the fact that it remains above80 per cent, from over-load to one-quarter load. A general de-scription of this plant was given in The Canadian Engineerof August 31st, Igii, where full details of the installation weregiven. TheRobbia plant is situated on the border of Switzerlandand Italy.
