摘要： A wave energy converter system comprises two floats; a first being generally flat and heaving up and down in phase with passing surface waves on a body of water, and the second being elongated and heaving up and down out of phase with the passing waves. Preferably, the first float is annular with a central vertical opening therethrough, and the elongated float, with a weighted bottom end, extends vertically through the central opening of the first float. The two floats thus move out of phase with one another, thus providing a relatively large relative motion between the two floats giving rise to highly efficient energy conversion. Each float serves as a “ground” for the other; thus avoiding the need for anchoring the floats to the floor of the body of water.

摘要： A cutting device for cutting sheets of material wherein a cutting member co-operates with a bed of upstanding pins which support the sheet. Although the cutting member may be a knife, it is preferably composed of a line of upstanding pins which are sufficiently long to penetrate through the material to be cut and to enter the bed of upstanding pins. The cutting device may comprise two drums mounted for rotation in opposite senses about parallel axes, one drum carrying the cutting member and the other the bed of pins, the tips of the pins being aligned with the cylindrical surface of their associated drum.

摘要： A wave energy converter (WEC) for converting energy contained in surface waves on a body of water to useful energy comprises two floats movable relative to one another in response to passing surface waves. Both floats comprise expandable outer envelopes which have been expanded into full and firm shape. In one process, expansion is obtained by filling the floats with fluids, for example, air and water. The fluids can be pumped into the floats, or the floats can be mechanically expanded in the presence of the fluids for self filling owing to pressure differentials. In one embodiment, a float envelope can comprise of plurality of end to end connected length sections in nested or telescoped relationship. Expansion is obtained by pulling the telescoped sections out from one and other, for example, by pumping fluids into the telescoped sections.

摘要： A wave energy converter (WEC) includes a shell suitable for being placed within a body of water. The shell contains an internal oscillator comprising a “reaction mass” and a spring mechanism coupled between the reaction mass and the shell. The shell and internal oscillator are constructed such that, when placed in a body of water and in response to waves in the body of water, there is relative motion between the shell and the internal oscillator's mass. A power take-off (PTO) device is coupled between the internal oscillator and the shell to convert their relative motion into electric energy. In systems embodying the invention, the spring mechanism is designed such that its displacement or movement is less than the displacement or movement of the reaction mass. The spring mechanism may be any device which enables the reaction mass to undergo a given replacement while its displacement or movement is less than that of the reaction mass. This property enables the size of the WEC to be more readily controlled (e.g., made smaller).

摘要： A linear electric generator (LEG) includes sections of coils of an induction coil assembly (ICA) disposed along a distance d1 and apparatus for passing a permanent magnetic assembly (PMA) of length d2, where d2 is less than d1, along the coils for generating voltages and power in the coils in close proximity to the PMA. Unidirectional conducting elements are connected between the coils and output power lines to couple the voltages developed across excited coils to the output power lines without the unexcited coils loading down or dissipating the voltage developed across the output power lines.

摘要： An electric generator includes multiple coil sections and switches connected to the multiple coil sections for selectively interconnecting the coil sections in series, or in parallel, or in a series-parallel configuration across first and second power terminals for producing a controlled AC voltage across these power terminals. The electric generator, with its multiple coils and interconnecting switches permitting reconfiguration of the coils, enables systems subjected to widely varying conditions and forces, such as a wave energy converter (WEC), to be operated with increased efficiency. The generator may also include multiple windings which can be selectively interconnected into a wye or a delta configuration to also control the output voltage produced by the generator and increase the efficiency of the power conversion system, particularly at low values of voltage.

摘要： A magnetic braking system for inhibiting excessive motion between a float and a column intended to be placed in a body of water; with the float and column moving relative to each other as a function of the waves present in the body of water. The braking system includes a permanent magnetic assembly (PMA) mounted on, and attached to, one of the float and column and a coil assembly (or a conductive plate) mounted on, and attached to, the other one of the float and column. The braking system is mounted such that motion between the float and the column is inhibited when the displacement of the float relative to the column exceeds a predetermined operating range.
