Abstract: A system includes a turbomachine that includes a stator and a rotor. The rotor is configured to rotate about a rotational axis relative to the stator. In addition, the rotor includes a least one rotary blade, and the at least one rotary blade has a patterned structure of beams and cavities.

Abstract: An optical switching apparatus comprising a housing with first and second optical ports on the housing for receiving optical connectors, wherein the first and second optical ports are optically connected in a first state. A third and fourth optical port for receiving optical connectors are provided in the housing for which are optically connected in a first state. An optical switch within the housing optically connects the first optical port to the third optical port and optically connects that the second optical port to the fourth optical port in a second state, wherein the optical switch is mechanically actuated due to insertion of an optical connector in at least one of the first and second optical ports. A sliding cam against a ball bearing accurately re-aligns two fiber optic arrays to switch from a first state to a second state.

Abstract: An array of rotor blades is provided. The array includes a rotor disk defining a plurality of slots. A first rotor blade that includes a first platform between a first airfoil and a first shank portion is coupled with a first slot of the rotor disk via the first shank portion. The first rotor blade further includes a pair of oppositely disposed flanges positioned between the first platform and the first shank portion and extending beyond a longitudinal side edge defined by the first platform. A second rotor blade, that includes a second platform defining a pair of oppositely disposed overhang lips and positioned between a second airfoil and a second shank portion, is coupled with a second slot of the rotor disk via the second shank portion. The second rotor blade is positioned adjacent to the first rotor blade such that one of the overhang lips of the second platform is positioned over one of the flanges of the first rotor blade.

Abstract: A method of making a supported gas separation molecular sieve membrane. In this method a porous support, which is preferably pretreated, is contacted with a molecular sieve synthesis mixture under hydrothermal synthesis conditions. The contacting step is conducted for a shortened crystallization time period. The resulting coated porous support is calcined to yield the supported gas separation molecular sieve membrane having particularly good gas separation characteristics.
