The intermediate portion may have an exposed section with multiple openings located in the exposed section. The intermediate portion may also have multiple blades extending from inner surfaces of all or some of the openings. The blades cause airflow to pass through the openings to cool the intermediate portion. | 10-14-2010 |
| 20100282550 | MODE ALTERING INSERT FOR VIBRATION REDUCTION IN COMPONENTS - A component with a first number of natural modes of vibration. An insert may be coupled to the component. The insert may have a second number of natural modes of vibration which is a different number than the first number of natural modes of vibration of the component. The insert helps damp vibrations in the component when the component is vibrated. | 11-11-2010 |
