Abstract: Covers on bucket tips are provided with an access slot along a circumferentially facing edge of the cover at a location where moisture removal grooves of the bucket will intersect with the cover. Machine tooling is then applied to form the grooves along the suction side and adjacent the leading of the bucket. The machining runs out through the access slot forming grooves along the side edge of the bucket cover within the slot. The axial extent of the covers overlying leading and trailing edges of the buckets is maintained while enabling moisture removal by centrifugal action.

Abstract: A turbine bucket includes a shank portion, an adjacent and radially inner dovetail mounting portion, an adjacent and radial outer airfoil portion, with a platform at a radially inner end of said airfoil portion adjacent the shank portion, and an integral cover at a radially outer tip of the airfoil portion, wherein the shank portion is shaped to provide a torque zone establishing a desired torque characteristic for the bucket to create, upon insertion into a dovetail groove on a turbine wheel, a desired contact pressure between the integral cover and adjacent covers in a row of similar buckets.

Abstract: A gaseous fuel-enriching subsystem for an internal combustion engine includes a supplemental intake conduit to a an intake manifold internal combustion engine. Such supplemental input is provided with numerus apertures therein. An exhaust gas conduit from the internal combustion engine annularly surrounds the intake conduit permitting fuel values from exhaust in the exhaust conduit to enter the supplemental intake conduit through such apertures. A water supply input to the supplemental intake conduit, at a end opposite to the location of the manifold, provides a further fuel input to the supplemental intake conduit in that water from the water supply is evaporated and then hydrolyzed, separating the water into its chemical constituents of hydrogen and oxygen, thusly producing an enriched gaseous fuel mixture with the recycled exhaust gas which is fed to the manifold.
