A wind turbine includes a quartet of pivot shafts that are in paired parallel relationship and transversely mounted on a central drive shaft. each pivot shaft supports a pair of wings at opposed ends thereof, the wings offset by 90°. Each pivot shaft rotates cyclically through 90° to move each wing from a wind-engaging orientation (drive position) in which the wing presents a flat surface approximately transverse to the incident wind, to a minimum drag position (glide position). In addition, the two wings of each pair on a shaft are disposed in planes that are offset by approximately 90° about their pivot shaft, so that one is in the drive position while the other is in the glide position. The wings of each pair of pivot shafts have wings at the ends thereof that open into the drive position at the same time and rotational angle of the turbine. A backstop at the site of each drive position supports the wind load and transfers its force to the central drive shaft.

A composite acoustic wave device provides improved protection from environmental factors while maintaining high electrical characteristics and dynamic range is provided. The device comprises a rigid protector plate having high quality acoustical characteristics and a thickness which is a multiple of half wavelength of the resonant frequency. A piezoelectric plate is coupled to the protector plate, is supported therefrom, and forms an energy interface therewith. The piezoelectric and protector plates are dimensioned such that a wave of resonant frequency traveling between the excitation face and the loaded/sensing face, forms a substantially continuous-phase wave, at substantially peak amplitude, at the energy interface. By doing so the device decouples the electrical thickness of the wave device from the mechanical thickness thereof.

A radiation system includes a radiation generator to generate a beam of radiation, a source, and an illumination system configured to receive the beam of radiation and provide a projection beam of radiation.

The beam measuring system may include several position sensors, the readouts of which can be used to determine incorrect alignment of the radiation source with respect to the illumination system. Diaphragms are connected to the collector of the radiation generator, so that in addition to X, Y, and Z corrections, Rx, Ry and Rz corrections are possible.

A method of operating a superconducting switch system to protect against quenching in a superconducting magnet circuit is provided. The system comprises a magnet circuit, a main superconducting switch and an auxiliary superconducting switch connected in parallel thereto by low resistance connecting parts. In an initial magnet energisation procedure, after establishing superconducting flow in the circuit, the main and auxiliary switches are closed to cause current to persist in the circuit without further power input. If the main switch quenches, the current will transfer to the auxiliary switch through the resistive connecting parts. Upon restoring the main switch to the superconducting state, the voltage drop through the resistive connecting parts will drive the current back through the main switch. A preconditioning procedure is carried out as part of the magnet energisation procedure to ensure that opening the main switch will establish superconducting current through the auxiliary switch.

A universal three dimensional motor generator system is provided with magnets and permanent magnetic and/or electromagnetic windings on rotors and stator for compounding and multiplying the order of voltage or potential to or from a machine. Three rotating rotors mechanically interconnected through gears and coils are strategically positioned within a housing that allows the multiple input and/or output of single and/or three phases A/C, D/C or in combination. When input power is supplied to rotor one, rotor two and rotor three start rotating along with rotor one due to gear arrangement to generate/ produce power which is fed back to rotor one. This generated/produced power can/will be utilize to supplement the input power to maintain the synchronous speed across the designed load or combined to increase the output rating of machine. The system allows multiple wiring configurations allowing each section of a rotor and stator configuration to operate independently or separately as a motor or generator, or in combination.

A radiation concentrator incorporating a main radiation concentrator (160) and an auxiliary radiation concentrator (161) that concentrates the incident radiation to the common receiver (3) is presented. The primary reflector (1) of the main concentrator (160) consists of two confocal parabolic reflectors (5a &5b) on either side of the axial plane in such a way that their parabolic axes points at the centers of the diagonally opposite halves of the radiation source. The main concentrator (160) is configured in such a way that a part of the radiation reflected from every point on its primary reflector (1) is absorbed by the receiver (3) directly and its secondary reflector (2) reflects the other part of the radiation to the receiver (3). The auxiliary concentrator (161) concentrates a substantial part of the incident radiation, which would have been blocked by the secondary reflector (2), to the receiver (3).
