Abstract
Abstract A new type of power generating plant that utilizes the motion of ocean waves to drive turbine generators in a power station; the plant including a series of underwater units each of which includes a hollow sphere that floats upon the water so that it rises and falls as waves move by, the ball being mounted on an end of a pivoting arm to which there is connected a piston slidable in a cylinder so to pump ocean water through a duct to the turbines in the power station.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
170 words
In a one way valve pressure pump turbine generator station assembly, the combination of an apparatus installed underwater in a sea, a power station ashore installed with turbine generators, and a duct between said apparatus and said generators, said apparatus comprising a plurality of units each of which consist of a cylinder having inlet ports for receiving sea water, an outlet port for delivering said sea water into said duct, a piston inside said cylinder, a piston rod of said piston being connected to an arm pivoted at one end about a pivot pin on a stationary post, an opposite end of said arm having a hollow ball filled with air for floating on a surface of said sea, wherein one way valves are installed at said inlet and outlet ports and along said duct, wherein an air line communicates between pumps upon a shore and an interior of said ball, and an opening in a lower end of said ball for said sea water entering or leaving said ball.
Claim 2
Dependent Claim
170 words
In a one way valve pressure pump turbine generator station assembly, the combination of an apparatus installed underwater in a sea, a power station ashore installed with turbine generators, and a duct between said apparatus and said generators, said apparatus comprising a plurality of units each of which consist of a cylinder having inlet ports for receiving sea water, an outlet port for delivering said sea water into said duct, a piston inside said cylinder, a piston rod of said piston being connected to an arm pivoted at one end about a pivot pin on a stationary post, an opposite end of said arm having a hollow ball filled with air for floating on a surface of said sea, wherein one way valves are installed at said inlet and outlet ports and along said duct, wherein an air line communicates between pumps upon a shore and an interior of said ball, and an opening in a lower end of said ball for said sea water entering or leaving said ball.
Claim 3
Dependent Claim
65 words
The combination as set forth in claim 1 wherein said cylinder includes an upper and lower chamber formed by said piston therebetween, said lower chamber having said inlet and outlet ports and said one way valves, while said upper chamber also has generally like inlet and outlet ports and one way valves, said upper chamber communicating with a second duct communicating with said turbine generators.
