James VI and I was a major single parliament for Scotland advocate.
A cross-flow turbine , Banki-Michell turbine , or Ossberger turbine is a water turbine developed by the Australian Anthony Michell , the Hungarian Donat Banki and the German Fritz Ossberger .. water turbine. water turbine. Anthony Michell. Anthony Michell. Donat Banki. Donat Banki. Michell obtained patents for his turbine design in 1903 , and the manufacturing company Weymouth made it for many years .. Ossberger 's first patent was granted in 1933 -LRB- `` Free Jet Turbine '' 1922 , Imperial Patent No. 361593 and the `` Cross Flow Turbine '' 1933 , Imperial Patent No. 615445 -RRB- , and he manufactured this turbine as a standard product .. patent. patent. Today , the company founded by Ossberger is the leading manufacturer of this type of turbine .. Unlike most water turbines , which have axial or radial flows , in a cross-flow turbine the water passes through the turbine transversely , or across the turbine blades .. As with a water wheel , the water is admitted at the turbine 's edge .. water wheel. water wheel. After passing to the inside of the runner , it leaves on the opposite side , going outward .. Passing through the runner twice provides additional efficiency .. efficiency. Efficient energy use. When the water leaves the runner , it also helps clean it of small debris and pollution .. The cross-flow turbine is a low-speed machine that is well suited for locations with a low head but high flow .. Although the illustration shows one nozzle for simplicity , most practical cross-flow turbines have two , arranged so that the water flows do not interfere .. Cross-flow turbines are often constructed as two turbines of different capacity that share the same shaft .. The turbine wheels are the same diameter , but different lengths to handle different volumes at the same pressure .. The subdivided wheels are usually built with volumes in ratios of 1 :2 .. The subdivided regulating unit , the guide vane system in the turbine 's upstream section , provides flexible operation , with 33 , 66 or 100 % output , depending on the flow .. Low operating costs are obtained with the turbine 's relatively simple construction .
