Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
An electric generator system comprising an electric generator, a gas operated turbine drivingly connected to said generator, a gas receiver on the inlet side of said turbine, a wind inlet stack connected at its exit end to said gas receiver, inlet means for wind at the entrance end of said stack, an exhaust stack connected at its entrance end to the exhaust side of said turbine and adapted to discharge exhaust gases through its exit end, and means in said exhaust stack for heating said exhaust gases to enhance the flow.
Claim 2
Dependent Claim
91 words
An electric generator system comprising an electric generator, a gas operated turbine drivingly connected to said generator, a gas receiver on the inlet side of said turbine, a wind inlet stack connected at its exit end to said gas receiver, inlet means for wind at the entrance end of said stack, an exhaust stack connected at its entrance end to the exhaust side of said turbine and adapted to discharge exhaust gases through its exit end, and means in said exhaust stack for heating said exhaust gases to enhance the flow.
Claim 3
Dependent Claim
91 words
An electric generator system comprising an electric generator, a gas operated turbine drivingly connected to said generator, a gas receiver on the inlet side of said turbine, a wind inlet stack connected at its exit end to said gas receiver, inlet means for wind at the entrance end of said stack, an exhaust stack connected at its entrance end to the exhaust side of said turbine and adapted to discharge exhaust gases through its exit end, and means in said exhaust stack for heating said exhaust gases to enhance the flow.
Claim 4
Dependent Claim
91 words
An electric generator system comprising an electric generator, a gas operated turbine drivingly connected to said generator, a gas receiver on the inlet side of said turbine, a wind inlet stack connected at its exit end to said gas receiver, inlet means for wind at the entrance end of said stack, an exhaust stack connected at its entrance end to the exhaust side of said turbine and adapted to discharge exhaust gases through its exit end, and means in said exhaust stack for heating said exhaust gases to enhance the flow.
Claim 5
Dependent Claim
26 words
A system as claimed in claim 1 comprising means at the outer end of said inlet stack for capturing gases moving in a substantial horizontal direction.
Claim 6
Dependent Claim
36 words
A system as claimed in claim 2 in which said means for capturing gases swivels on said stack and contains vanes adapted to adjust the position of said means in the direction of maximum gas flow.
Claim 7
Dependent Claim
26 words
A system as claimed in claim 1 comprising means at the exit end of said exhaust stack for discharging exhaust gases in a substantial horizontal direction.
Claim 8
Dependent Claim
37 words
A system as claimed in claim 1 in which said means for discharging gases swivels on said exhaust stack and contains vanes adapted to adjust the position of said means in the direction of maximum gas flow.
Claim 9
Dependent Claim
25 words
A system as claimed in claim 1 in which said exhaust stack is adapted to carry a larger volume of gas than said inlet stack.
Claim 10
Dependent Claim
18 words
A system as claimed in claim 1 comprising means to control the flow of gases in said system.
Claim 11
Dependent Claim
45 words
A system as claimed in claim 1 in which said inlet stack contains a damper ahead of said receiver, a passageway connects said inlet stack to said exhaust stack at a point between said damper and said inlet means, anD said passageway contains a damper.
Claim 12
Dependent Claim
24 words
A system as claimed in claim 8 comprising means to control the operation of said dampers in response to gas requirements of said turbine.
