Abstract: A coupling device that requires no manual actuation to achieve coupling features a locking bolt movable along a hole extending into a mouth of a hook body to secure a coupling pin therein. A control lever pivotally connected to the locking bolt opposite the mouth end is biased toward a locked position in which motion of the locking bolt is blocked. To engage the coupling pin and the hook mouth, the coupling pin and an operable pin extending through the hollow locking bolt are brought into contact. This causes an end of the operable pin opposite the mouth to push against the control lever to unlock it from the latching position. The coupling pin pushes the locking bolt out of the mouth so that it can pass by further into it, at which point the lever and bolt return to the locked positions to secure the coupling pin inside.

Abstract: Systems and methods for actuating a pair of pipe flanges to cause the flanges to be sealingly engaged. In one embodiment, a connection includes a first flange, a second flange and a coupling. The first and second flanges have complementary mating surfaces. The coupling engages both the first and second flanges, with the flanges oriented so that their mating surfaces face each other. The coupling movably engages the first flange to form a cavity between the coupling and the flange. When fluid is forced into the cavity, expansion of the cavity moves the first mating surface toward the second mating surface. This is continued until the mating surfaces make contact and a desired amount of pressure is applied between them to create a seal. The pressure of the fluid is distributed evenly through the cavity, so the contact pressure between the mating surfaces of the flanges is also evenly distributed.

Abstract: A wavefarm (10) comprises a multiplicity of wave energy converters, comprising linear generators (19, 20, 21) and (22) which are driven by floats immersed in the sea, (14). In normal wave conditions, all of the generators supply a land line (17) via a control unit (18). In the event of inclement conditions, one or more of the generators are switched to linear motors, and these are then powered by those generators remaining in the sea, to withdraw their floats into protective cavities (23). The process is repeated sequentially until all but the last one or few of the generators have withdrawn their floats. Finally, these last are withdrawn by connecting them to an alternate power source e.g. a battery, (24), again via the control unit (18).

Abstract: A hydraulic buoyancy kinetic energy apparatus includes two buoys which are located at an upper position and a lower position respectively.
