Wave-motor system

Claim 2

A machine for converting energy of sea waves to useful work comprising: flotation means, an energy conversion device having an impact vane positioned generally above the surface of the low point of the waves and a discharge to the water surface, said device being actuated by water impacting on said vane and forcing it down to the surface of the water on the discharge side of said device, a ramp carried by said flotation means and constructed and arranged to convert waves into breakers, and means for raising and lowering said flotation means in the water to cause the water in approximately the top half of the breakers to be moving generally horizontally forward at the time they impact against said vane of said energy conversion device.

Claim 3

The machine of claim 1 wherein said energy conversion device comprises: an impact panel hinged at the bottom about a horizontal axis for movement from a generally vertical position to a generally horizontal position by water moving from said inlet down to the surface of the water at said discharge.

Claim 4

The machine of claim 1 wherein said impact vane drives an electric generator for producing a pulsating D.C. voltage the frequency of which is basically that of the sea waves, an electrolytic cell driven by said generator for producing hydrogen at the pulsing frequency of the sea waves, and accumulator means for said hydrogen which will smooth out the pulsations of hydrogen.

Claim 5

A machine for converting energy of sea waves to useful work comprising: flotation means relative to which the surface of the surrounding water rises and falls as the crests and valleys of waves move therepast; an energy conversion device having an impact vane supported from said flotation means above the valleys of waves passing the flotation means and a discharge to the water surface of walleys flowing therepast, said device being actuated by water flowing from said impact vane down to the surface of the water on the discharge side of said device; and an inclined ramp carried by said flotation means ahead of said impact vane and over which waves pass before impacting said vane, said ramp being constructued and arranged to produce a generally maximum wave height at said impact vane and to hold said flotation means down when said maximum height impacts said vane and to rise as the water of the wave moves said impact vane.

Claim 6

A machine for converting energy of sea waves to useful work comprising: flotation means relative to which the surface of the surrounding water rises and falls as the crests and valleys of waves move therepast; an energy conversion device having an impact vane supported from said flotation means above the valleys of waves passing the flotation means and a discharge to the water surface of walleys flowing therepast, said device being actuated by water flowing from said impact vane down to the surface of the water on the discharge side of said device; and an inclined ramp carried by said flotation means ahead of said impact vane and over which waves pass before impacting said vane, said ramp being constructued and arranged to produce a generally maximum wave height at said impact vane and to hold said flotation means down when said maximum height impacts said vane and to rise as the water of the wave moves said impact vane.

Claim 13

The method of claim 7 including the further step of: utilizing the movement of a wave as it approaches said impact vane to produce a force on said flotation means which reduces the flotation effect of a crest adjacent said water impact vane.

Claim 14

Apparatus for converting energy of sea waves to useful work comprising: an impact vane moveable from a generally vertical position to a generally horizontal position; a ramp beneath the water level and leading upwardly to said impact vane and constructed and arranged to convert the sea waves into breakers; and means for raising and lowering said ramp so that the breakers have approximately the top half of the water therein moving generally horizontally forward at the point where said impact vane is in its generally vertical position.

Claim 15

Apparatus for converting energy of sea waves to useful work comprising: an impact vane moveable from a generally vertical position to a generally horizontal position; a ramp beneath the water level and leading upwardly to said impact vane and constructed and arranged to convert the sea waves into breakers; and means for raising and lowering said ramp so that the breakers have approximately the top half of the water therein moving generally horizontally forward at the point where said impact vane is in its generally vertical position.

Claim 16

The apparatus of claim 9 wherein said ramp and impact vane are supported by a flotation device using water as a ballast; and said means adds water to or takes water out of said ballast.

Claim 17

The apparatus of claim 10 wherein said flotation device comprises twin hulls respective ones of which are located on opposite sides of said impact vane.

Claim 18

Apparatus for converting energy of sea waves to useful work comprising: flotation means adapted to be raised and lowered relative to a normal water line by adding water to and removing water therefrom, said flotation means having sidewalls, an open front, and a rear wall extending from a point below the normal water line to a point above the normal water line; an impact vane hinged about a horizontal axis adjacent the top of said rear wall for movement between a generally vertical position and a horizontal position; and a ramp extending from a point beneath the normal water line and adjacent the front end of said flotation means angularly upwardly to a point adjacent the top of said rear wall, said ramp being carried by said flotation means for raising and lowering relative to said normal water line.

Claim 19

Apparatus for converting energy of sea waves to useful work comprising: flotation means adapted to be raised and lowered relative to a normal water line by adding water to and removing water therefrom, said flotation means having sidewalls, an open front, and a rear wall extending from a point below the normal water line to a point above the normal water line; an impact vane hinged about a horizontal axis adjacent the top of said rear wall for movement between a generally vertical position and a horizontal position; and a ramp extending from a point beneath the normal water line and adjacent the front end of said flotation means angularly upwardly to a point adjacent the top of said rear wall, said ramp being carried by said flotation means for raising and lowering relative to said normal water line.

Claim 20

The apparatus of claim 12 having a curved vane cover fixed to said flotation means for confining water to said vane as it moves from its vertical position to a generally horizontal position.
