|PCT/CN2013/075626||QU, Yanming||QU, Yanming|
A return spring adjustment apparatus and method of a wave power system. The apparatus comprises return springs (5, 9), a stepper motor (6), transducers (7, 10, 27, 29), a single chip microcomputer control module (8) and a power source. The two ends of the return springs (5, 9), a chassis (12) of the stepper motor, a rotor (11), the two ends of the transducers (7, 10, 27, 29) can all be randomly arranged in series, and connected with a spindle (4) and a frame (22). When a single chip microcomputer detects that the transducers (7, 10, 27, 29) measure that the pulling force is too large or too small, it sends an instruction to the stepper motor (6) to perform adjustment. After the adjustment is completed, the stepper motor (6) stalls and brakes, so that the return springs (5, 9) can work in within a specified range.

|PCT/JP2013/064194||YAMAGUCHI UNIVERSITY||HADANO, Kesayoshi|
The present invention provides a water-retarding chamber structure capable of reducing construction cost and increasing energy gain. A water-retarding structure for a wave-power energy conversion device for wave-power generation that converts wave energy into mechanical energy using the vertical motion of the water surface, wherein a perpendicularly oriented parallel wall is disposed parallel to the installation surface of the structure, and the space between the installation surface and the parallel wall is divided by a perpendicularly oriented partition wall, whereby a configuration is adopted in which a group of water-retarding chambers created by arranging a plurality of water-retarding chambers in a row along the installation surface is formed, and the direction in which the water-retarding chambers are arranged has the same orientation as the direction of motion of the waves. The end section of the parallel wall and the installation surface are diagonally linked at the end section of the group of water-retarding chambers, a perpendicularly oriented waveguide wall being disposed to suppress the force of impact of waves acting on the end section of the group of water-retarding chambers.
|5.||WO||WO/2013/174875 - THERMOSTATIC ELEMENT||28.11.2013||
This element (101) comprises a cup (110) containing a thermally expanding material (120), a piston (130) capable of translational movement along its axis (X-X), a rigid guide (140) for guiding the translational movement of the piston, a seal (150) for sealing in the thermally expanding material having an annular overall shape, centred on the axis and through which the piston passes axially right through, and which includes first (152) and second (153) opposite axial parts against which the guide and the cup press respectively in a substantially antagonistic manner so as to compress the seal around the piston, and an anti-extrusion washer (160) mounted coaxially around the piston and axially interposed between the guide and the first part of the seal. The invention provides for including in this thermostatic element means (144) for supercompressing the first part of the seal around the piston, which means are designed to make the degree of compression of the first part of the seal equal to a value strictly higher than that associated with an operational thermostatic element formed by the cup, the piston, the guide, the seal and the anti-extrusion washer assembled with one another without these supercompression means.

|PCT/MX2013/000065||ORTEGA GARCÍA, Miguel de Jesús||ORTEGA GARCÍA, Miguel de Jesús|
The invention relates to an independent wave capture module that converts ocean waves into electrical energy. The module generates electrical energy by means of the capture of the waves by the buoy of a primary lever and the buoy of a secondary lever. The two levers convert the amplitude and frequency of the waves into the driving rotation of the drive shaft of the right-hand composite reel and the left-hand composite reel. The timing of the drive and return cycle of the primary lever is different to that of the secondary lever, without the action of one interfering with that of the other. The right-hand drive reel together with the left-hand composite reel drive the drive shaft in the driving direction at low revolutions, and inside the generation chassis the low revolutions of the drive shaft, stabilised by the flywheels, are multiplied by the speed-increasing gearbox and converted into electrical energy by the electrical generator.

|PCT/GB2013/051325||CAMBRIDGE MECHATRONICS LIMITED||EDDINGTON, Robin|
An SMA actuation apparatus moves a movable element relative to a support structure in two orthogonal directions using a total of four SMA actuator wires each connected at its ends between the movable element and the support structure and extending perpendicular to the primary axis. None of the SMA actuator wires are collinear, but the SMA actuator wires have an arrangement in which they are capable of being selectively driven to move the movable element relative to the support structure to any position in said range of movement without applying any net torque to the movable element in the plane of the two orthogonal directions around the primary axis. Accordingly, it is possible to drive movement whilst balancing the forces to limit torque around the primary axis.
