摘要:
The interior of a stator bar clip that is joined to the end of a stator bar is electroplated so that a metallic barrier coating overlies the braze joint between the stator bar and the clip to define a seal at and around the joint that is substantially impermeable to liquid.

A fan is provided for use with a casing having a bellmouth and a conduit portion. The fan has a hub, a number of blades extending from the hub, and a shroud. In cooperation with the casing and the conduit portion surrounding the shroud, the shroud has means for generating a separation bubble effective to limit a recirculation flow.

摘要:
A rotor core and winding assembly including: separable rotor core sections assembled to form the rotor core, where the core sections each have a substantially circular perimeter and are axially aligned when assembled as the core, and the winding assembly includes a pre-assembled superconducting field winding and a winding support, wherein the winding support extends between adjacent core sections in the assembled rotor core.
摘要:
Conformationally restricted polyamine compounds useful in treatment of cancer and other diseases marked by abnormal cell proliferation are disclosed. Improved methods of synthesizing such compounds are also disclosed. In one method of the invention, a carbene-bearing or carbene equivalent-bearing compound is reacted with the double bond of an alkene compound to form a cyclopropyl ring as the first step in the synthesis.
摘要:
Devices based on surface plasmon filters having at least one metal-dielectric interface to support surface plasmon waves. A multi-layer-coupled surface plasmon notch filter is provided to have more than two symmetric metal-dielectric interfaces coupled with one another to produce a transmission spectral window with desired spectral profile and bandwidth. Such notch filters can form various color filtering devices for color flat panel displays.
