Abstract
Abstract A turbine-compressor for feeding a gas to a combustion chamber. Within a housing having an inner cylindrical wall, is a rotor having circumferentially grooved passages. One portion of the housing inner cylindrical wall contains the inlet and exhaust sections and somewhat opposite the inlet and exhaust section is the combustion section. At the one, and at the other of these sections is an inner and outer, somewhat radial wall, having an adjustable orientation. These radial walls have teeth which enter the circumferentially grooved passages making a substantially sealed contact with the rotor. These walls and teeth form gas flow guides. The rotor is rotated at over about 1100 feet per second, forcing the gas into the combustion chamber where burning occurs. The fluid then reenters the casing through a nozzle and expands through the turbine side of the casing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
144 words
A turbine-compressor comprising in combination: a. a housing having an inner cylindrical wall with an intakeexhaust section and a combustion section defined along portions of said wall, b. a rotor disposed for rotation within said cylindrical wall with a plurality of circumferential passages thereon, c. a stripper component in each of said sections including teeth-like or comb-like shapes penetrating into said circumferential passages to form a barrier in said sections defining said inlet and exhaust sections and providing gas flow guides from the inlet section to the combustion section along one side of such wall and from the combustion chamber to the exhaust section along the other side of said wall and, d. at least one choke comb along said wall including means permitting said choke comb to swing in and out of the rotor circumferential passages to vary, at will, their crosssectional areas.
Claim 2
Dependent Claim
144 words
A turbine-compressor comprising in combination: a. a housing having an inner cylindrical wall with an intakeexhaust section and a combustion section defined along portions of said wall, b. a rotor disposed for rotation within said cylindrical wall with a plurality of circumferential passages thereon, c. a stripper component in each of said sections including teeth-like or comb-like shapes penetrating into said circumferential passages to form a barrier in said sections defining said inlet and exhaust sections and providing gas flow guides from the inlet section to the combustion section along one side of such wall and from the combustion chamber to the exhaust section along the other side of said wall and, d. at least one choke comb along said wall including means permitting said choke comb to swing in and out of the rotor circumferential passages to vary, at will, their crosssectional areas.
Claim 3
Dependent Claim
15 words
A turbine compressor as in claim 1 wherein said circumferential passages are of rectangular cross-section.
Claim 4
Dependent Claim
16 words
A turbine compressor as in claim 1 wherein said circumferential passages are of truncated triangular cross-section.
Claim 5
Dependent Claim
43 words
A turbine-compressor as in claim 1 wherein said rotor has circumferential passages sealed to the housing by labyrinth type grooves cut into the housing and wherein said stripper sections are grooved to form labyrinth seals to prevent gas flow through said stripper sections.
Claim 6
Dependent Claim
119 words
A turbine-compressor comprising in combination a housing having an inner cylindrical wall with an intake-exhaust section and a combustion section defined along portions of said wall, a rotor having a plurality of circumferential passages thereon disposed for rotation within said cylindrical wall, a stripper component in each of said sections including teeth penetrating into said circumferential passages to form a barrier in said sections defining said inlet and exhaust sections and providing gas flow guides from the inlet section to the combustion section along one side of such wall and from the combustion chamber to the exhaust section along the other side of said wall, and means for radially adjusting the position of said teeth in said circumferential passages.
Claim 7
Dependent Claim
119 words
A turbine-compressor comprising in combination a housing having an inner cylindrical wall with an intake-exhaust section and a combustion section defined along portions of said wall, a rotor having a plurality of circumferential passages thereon disposed for rotation within said cylindrical wall, a stripper component in each of said sections including teeth penetrating into said circumferential passages to form a barrier in said sections defining said inlet and exhaust sections and providing gas flow guides from the inlet section to the combustion section along one side of such wall and from the combustion chamber to the exhaust section along the other side of said wall, and means for radially adjusting the position of said teeth in said circumferential passages.
Claim 8
Dependent Claim
29 words
A turbine-compressor as in claim 5 wherein said adjusting means comprises bolts threadedly passing through a wall of said housing and engaging the stripper components to urge them inwards.
Claim 9
Dependent Claim
32 words
A turbine-compressor as in claim 6 wherein each bolt is provided with a biasing outer spring engaging between the housing and the head of the bolt to hold the bolt in position.
Claim 10
Dependent Claim
45 words
A turbine-compressor as in claim 5 wherein at least one of said stripper components comprises a laminated assembly of alternate teeth and spacing members provided with registering holes and a pin passes through said holes to hold said teeth and spacing members in assembled position.
Claim 11
Dependent Claim
22 words
A turbine compressor as in claim 8 wherein said holes and pin are shaped to maintain proper orientation of said laminated assembly.
Claim 12
Dependent Claim
19 words
A turbine compressor as in claim 5 wherein said circumferential grooves and teeth are of truncated triangular cross section.
