摘要： A new and improved wind turbine apparatus includes a housing assembly which includes an upper housing surface which includes a leading edge and a trailing edge. The upper housing surface is contoured to create a venturi action and to exert a reduced pressure at the trailing edge when wind flows across the upper housing surface from the leading edge to the trailing edge. A vane assembly is supported on a horizontal axle in a location such that vanes of the vane assembly are responsive to wind blowing in a direction from the leading edge to the trailing edge of the upper housing surface and such that the vanes are also exposed to reduced pressure near the trailing edge, whereby the vane assembly is caused to rotate on the horizontal axle. A base assembly supports the housing assembly and the vane assembly. The base assembly includes a circular guide assembly, and the housing assembly includes a guide-contacting portion for riding on the circular guide assembly in a circular movement. The circular guide assembly includes a flange, and the guide-contacting portion includes a guide wheel, supported by the housing assembly, for rolling against the circular guide assembly. An adjustable-pitch vane assembly may be used for adjusting pitch of the vanes with respect to the oncoming wind which contacts the vanes. An angular adjustment lock assembly is provided for locking the housing assembly at a selected angular orientation with respect to wind.

摘要： The invention concerns a hydrodynamic retarder, the stator blade wheel of which can be brought into eccentric, nonaligned positions with respect to the rotor blade wheel. Either by formation of a blade free circumferential region in the blading of the stator blade wheel together with a longitudinal guide for eccentric shifting or by eccentric swingable mounting of the stator blade wheel, a directly proportional force is obtained from the corresponding braking torque in the stator blade wheel. This force represents a measure for the braking torque and serves as a characteristic value for a torque adjustment. This creates a simple control device with characteristic curves which requires a smaller retarder profile diameter in order to obtain given operating points. The advantage is the reduction of the outside dimensions, the weight and the expense for regulating the brake torque.

摘要： Method and apparatus for automatically determining the set of optimal operating angles for the variable pitch blades of a Kaplan-type turbine which has movable gates and is controlled by a governor and an electronic 3D cam. The governor controls the gates so as to maintain the turbine at a predetermined setpoint power generation level, and on-cam values of particular operating parameters of the turbine are measured. When evaluation of the measured data indicates that the turbine is in a steady-state condition, the blades are moved through a series of incremental off-cam variations in pitch. Following each incremental pitch variation of the blades, the governor repositions the gates to return the turbine to the predetermined setpoint power generation level. The operation of the turbine is then monitored, and values of particular operating parameters are measured at the new gate-blade operating point once the turbine has returned to steady-state. An efficiency value is computed for each of the measured operating points and are compared to identify a peak efficiency value.

摘要： A steady operation method for a hydraulic machine such as a generator operating at a variable revolution speed is performed in accordance with the following steps. A head or load of the hydraulic machine is first detected and a basic signal is obtained on the basis of the thus detected value so as to control the revolution speed of the hydraulic machine. On the other hand, a vibration or hydraulic pressure variation is detected and the thus detected value is converted into an auxiliary signal through an auxiliary signal converter. The revolution speed of the hydraulic machine operating at a variable speed is controlled in such a manner as that the revolution speed is controlled by the basic signal when the auxiliary signal is below a predetermined upper limit thereof regarding the vibration or hydraulic pressure variation, and otherwise, the revolution speed is controlled by a signal other than the basic signal when the auxiliary signal is beyond the upper limit thereof.

摘要： A hydroelectric installation, comprising a hydraulic machine, such as a turbine, pump or pump turbine, wherein the rotor is coupled to the shaft of a synchronous alternating current electrical machine operating as an alternator, or as a motor. When operating as a turbine, the installation includes at least one set of rectifiers transforming the alternating current produced by the alternator into direct current. When operating as a pump, the installation includes at least one undulator transforming the direct current supplied by the electric line into alternating current and supplying the motor. In both instances the installation comprises a pilot device controlling the mechanism regulating the quantity of water flowing through the turbine, or the frequency of the current output of the undulator to maintain at any instant, the predetermined speed of rotation of the rotor of the machine regardless of the value of the hydraulic head existing at that moment.

摘要： A pool cleaning tool includes a front housing and a rear housing coupled together, an intake, an outlet, a turbine disposed within the front and rear housings, and a three-way diverter valve proximate the intake. The tool includes an abrasive member, rigidly coupled to the turbine, mounted outside the front and rear housings for rotation with the turbine. The three-way diverter valve has an on position in which water drawn into the intake is communicated into the tool, up to the turbine, and then out the outlet, thereby imparting rotation to the turbine and to the abrasive member.
