Patent CA-2490619-A1 (CA)
Title: Gas turbine ventilation circuitry
Inventor: TAILLANT JEAN-CLAUDE
IPC: F02C7/28
Filed: 2003-06-25
Abstract: The invention concerns the ventilation circuitry of a gas turbine rotor (1) comprising a turbine disc (3) an upstream side-plate (5) arranged upstream of a combustion chamber and separated therefrom by a cavity (12). A first cooling air circuit delivers air into the cavity (12) via main injectors (15) and holes provided in the side-plate (5). A second cooling air circuit delivers air through chambers delimited by the inner housing of the combustion chamber and the rotor via a discharge labyrinth, a sub-injector labyrinth and at least one labyrinth arranged downstream of the main injectors between an annular structure (27) and the side-plate (5). The invention is characterized in that there are provided three labyrinths (31, 32, 33) comprising each a leak-prevention unit downstream of the main injectors, and which define two cavities (34, 35) upstream of the purging cavity (20) of the turbine disc (3). One of said cavities (34, 35) is supplied with air tapped from the second circuit upstream of the sub-injector labyrinth through perforations (38) sloping tangentially in the rotational direction of the rotor and arranged in the annular structure (27).

Title: Improved elevated rail transportation system
Inventor: SCHLIENGER MAX P
IPC: B61B13/12
Filed: 2004-06-04
Abstract: A system for propelling a vehicle along an elevated, pneumatic power tube carried by exterior support structure above ground. First and second angles define tracks for the vehicle and extend parallel to the power tube.  Undercarriages secured to the vehicle including vehicle support and guidance wheels which are rotatable about axes inclined relative to legs of the angle tracks have a periphery that engages the legs of the angle tracks so that the weight of the vehicle is supported by the tracks and the support structure only. A pneumatic propulsion unit is movably disposed inside the power tube and is guided along rails on the inside of the power tube. A magnetic coupler having first and second cooperating magnetic elements is attached to the vehicle and the propulsion unit in operative alignment with each other. A  portion of the power tube located between the magnetic elements is constructed of a non-magnetic and non-conductive material and extends over the length of the power tube. The propulsion unit has a thrust carriage with a thrust valve that forms a collapsible, frusto-conically shaped wall formed by a multiplicity of overlapping, angularly inclined blades that are concentrically disposed in the power tube. An actuator is coupled to the blades for selectively increasing an angle of the blades until free ends thereof contact an interior surface of the power tube, to thereby prevent the flow of air through the tube past the wall, and for retracting the blades so that the free ends thereof are spaced apart from the interior surface of the power tube, the valve generating a force acting in the longitudinal direction of the power tube when the free ends of the valve blades engage the interior surface.
