摘要： In a nodding duck for extracting power from waves on water, a control system is incorporated for generating a feedback force related to one or more of the parameters of movement, viz. the displacement position, velocity or acceleration of the duck. The relationship between the feedback force and the parameter is chosen to control the response of the duck for example to enhance the coupling between waves and the duck over a broader range of wave frequencies than would be practicable in the absence of the control system.

摘要： An instrument for sensing seismic waves and determining their direction of propagation is operable at considerable depth in a borehole. It comprises a short, stubby sensor module with means to clamp it to the borehole wall and including three accelerometers, and connected by a flexible umbilical cord to a primary module suspended by a cable. The down-hole electronics and the power supply for the clamp means are provided in the primary module. The sensor module has a fundamental resonant frequency about 1 kHz, well above the frequency of the seismic waves it is subjected to, so that the signals from the accelerometers accurately represent those waves.

摘要： The invention provides a device for extracting energy from waves on a liquid upon which the device is adapted to float. The device is allowed to move in response to the waves, and has a shape below the surface of the liquid, position of center of gravity, and value of radius of gyration about the center of gravity, in a vertical plane aligned in the direction of propagation of the waves, adapted so that the device in response to the waves inhibits to a substantial extent the transmission and/or reflection of waves by the device itself.

摘要： A wave power apparatus (10) includes a chamber (16) which may be constructed over a coastal gully (12) so that waves (14) cause the water level to rise and fall in the chamber, and so cause air to flow to and fro in a duct (32). A Wells-type biplane turbine (34) in the duct (32) drives a generator (36). The turbine (34) comprises two turbine discs (45) 0.5 m apart, each defining a hub, a plurality of aerofoil section straight blades (80), and an outer ring (56). The ring (56) is sufficiently massive to act as an energy-storage flywheel, and has a greater moment of inertia than the hub and the blades. Each turbine disc (45) might have a kinetic energy of at least 1 MJ when rotating at 1650 rpm.

摘要： A device and a method for extracting energy from waves on a liquid from the oscillations of a column 14 of liquid in a chamber 22. The oscillations are caused by an oscillatory excitation force `Fe` produced by the effect of the waves. The phase of the velocity `z` of the column 14 of liquid and the phase of the excitation force `Fe` are brought substantially into phase by arresting the motion of the column 14 of liquid, and holding the column 14 of liquid stationary until the column 14 of liquid can be released in phase with the excitation force `Fe`.

摘要： The invention relates to a method of forming a metal-resin bond in the presence of environmental contamination of the metal surface by, for example, adsorbed water. The method consists of cleaning the metal surface and then coating it with a pre-treatment material adapted to displace the adsorbed contaminant and to be displaced in turn by the applied resin. The method is particularly relevant to the formation of steel/epoxy resin bonds underwater for the repair of submerged structures. The pre-treatment material may consist of a hydrocarbon solvent containing in solution a surfactant such as an ionic surfactant together with a viscous hydrocarbon such as petroleum jelly.
