Full Text	The present invention relates t.o a horizontal open-cross flow turbine useful as a multi purpose power unit, utilising the inherent energy available in water streams in hills in situations where- sufficient head and water flow he available to develop 3 KW—10 K.W power. Based on the turbine technology1 a new design with low cost fabrication technology has, been developed to enable develop both mechanical and electrical power from water streams for multi-purpose applications in hills. The idea of converting potential energy of water into mechanical energy has been known to mankind for centuries. In the earlier days this potential was converted by passing flowing water through wooden wheels known as water mills. These water mills are still in use for grinding purposes. However, these mills are basically single purpose devices i.e. they can only grind wheat, but cannot, for example, dehusk paddy make flattened rice or "Chewra", expel oil or generate electricity. The traditional water mills also have extremely low output and do not provide enough economic surplus to the mill owners. Keeping this in view, a simple but efficient multi-purpose machine of low cost and long life has been developed for use at such water mill sites where hydro potential in the water streams be of the order of 3-10 kW. The main objective of the present invention is to provide a simple machine to produce mechanical and electrical power using the hydro potential available in almost every water stream in hills. The invention is the first of its type, which is capable of producing utp 10 kW of mechanical power for driving agro-proceessing machines directly and for generating electricity if connected with an alternator. Yet another objective of the present invention is to provide a machine of low cost and long life which is very compact, whose parts and installation parameters are easy to understand by the existing watennill owner and which require very less maintenance in the long run. In order to have a simple and economically viable machine, a horizontal open cross flow turbine has been developed. The runner of the turbine is successfully cast in iron, which is a unique task, as everywhere else in the world the runners of cross flow turbine are fabricated, not cast. The casting process makes the runner stronger and very economic in comparison to fabrication. It also requires fewer skills at the level of a village workshop, thus making transfer of technology easier. The nozzle with valve is fabricated from MS sheet. In order to reduce the cost of the machine, the turbine is installed without a casing (the conventional cover) as the casing in this type of turbine does not impact upon the efficiency of die turbine. A casing is required only to protect the splashing of water over the turbine and mainly over the bearings, Otherwise bearings will have to be protected from water by providing seals which are expensive. To avoid this additional cost of seals, the layout of the system is designed in such a manner that the runner is over¬hung with the shaft mounted on the bearings. Both bearings are at one side of tii e runner and in-side the wall of the building. The runner along with the nozzle is installed outside the building so that the water splashes remain outside and not over the bearings and hence bearings are protected from water. The working of the device is that Water from penstock strikes the runner through nozzle in the from of a jet with the result that die runner rotates, moving in turn the driving pulley fitted at the other end of the shaft. The mechanical power developed by the device can be used to drive a single agro -processing machine directly or more than one machine simultaneously through a counter shaft. Electricity can also be generated if the generator/alternator is connected as one of the end use machine with the system.
