Title<br />
The invention refers to a turbine set in motion by low head<br />
water energy, allowing the kinetic-potential energy<br />
conversion into mechanical energy capable to turn an<br />
electrical generator.<br />
By increasing of turbine output water speed, an hydraulic<br />
device, using the Coandă effect, placed before the conical<br />
ejector (the turbine aspirator) determines the increase of<br />
depression in the conical ejector’s region on its inner<br />
surface, fed with high hydraulic energy water from<br />
turbine’s upstream, leading to the indirect tuning of<br />
turbine rotation speed and increasing of its conversion<br />
efficiency at low head placements.<br />

Patent no. Patent application No. A/00783/04.08.2011<br />
Description<br />
The invention regards a process and a device of covering<br />
to an ambient temperature of a various range of yarns with<br />
mixtures made of miscible binders into aqueous solution<br />
or solvents and ferrimagetic powders or other types.<br />
The device permit the deposit of a thin magnetisable film<br />
on different yarns types as: carded, combed, simple and<br />
twisted, monofilamentary and polyfilamentary, seamless<br />
and twisted yarns. The covering process of the yarn (3) is<br />
made by extruding, when this is passing through mixture<br />
being located into a special room (10) and then helped by<br />
a calibration device (11) that limits the dimension of<br />
deposited layer on it. The ferimagnetic layer of yarn is<br />
magnetised along of magnetic field lines generated by an<br />
electromagneti induction coil (12). After magnetizing<br />
process occurs drying and fixing into a thermic chamber<br />
(13) followed by wrap on a bobbin with the system (14,<br />
