    Abstract: 9590. Berg, J. April 20. Actuating valves.-A time switch adapted for electric or other lighting purposes, of the kind in which the actuating-mechanism is unlocked in readiness for action a short period before the prearranged time of action comprises a cranked lever having an arm f adapted to be engaged by the timing mechanism, and an arm g having two projections e, g , which are adapted to engage a locking-lever i and a pawl l respectively. The lever i has an arm i , which normally engages notches in a cam k mounted on the main spindle o of the clock-train and connected to the switch or other device h, and an arm i , which normally engages a stop in the clock-train. When one of the hands b engages the arm f, the locking-lever i is moved out of engagement with the cam k and with the clocktrain, but this is prevented from rotation by the engagement of the pawl l with the projection g', until the continued movement of the hand b releases the arm f, which springs back to its normal position and leaves a free passage for the rotation of the pawl l.

    Abstract: A wave energy harvester (100A) includes an element (120A) that converts forward and/or backward of water in a wave (102A. B. C) passing the harveste r (100A) into upward and/or downward movement to thereby increase the vertical amplitude of the harvester (100A) relative to the sea floor (104A. B. C). In most preferred aspects, the element (120A) is a hydrofoil that is coupled to the harvester (100A). Further preferred aspects include those in which part of, or the entire harvester (100A) has a neutral buoyancy, and where energy is extracted from the downwards movement of the neutrally buoyant part (100A) after a wave has lifted that part (110A).
