| 20090000845 | MOTORCYCLE HAVING DETACHABLE SUPPORT MEMBERS - A motorcycle includes a steering head, a steering assembly pivotably coupled to the steering head, at least one longitudinal frame member extending rearwardly from the steering head, and a rear frame member coupled to the longitudinal frame member. The rear frame member includes a mounting portion having a mounting surface, and first and second walls extending from the mounting surface at an oblique angle to the mounting surface. The motorcycle also includes a support coupled to the rear frame member. The support includes a coupling portion having a coupling surface, and first and second walls extending from the coupling surface at an oblique angle to the coupling surface. The first and second walls of the mounting portion are wedged against the first and second walls of the coupling portion, respectively, to substantially prevent rotation of the support with respect to the rear frame member. | 01-01-2009 |
| 20090001113 | LUGGAGE RACK AND PASSENGER SEAT FOR A MOTORCYCLE - A luggage rack and passenger seat combination for a motorcycle includes a luggage rack assembly configured to mount to the motorcycle. The luggage rack assembly has a support member operable to support cargo on a support surface thereof, the luggage rack assembly including a first engaging feature and a second engaging feature. A passenger seat assembly includes a movable mounting member and a fixed mounting member. The movable mounting member is movable between an unlocked position and a locked position. The movable mounting member is engageable with the first engaging feature and the fixed mounting member is engageable with the second engaging feature to removably couple the passenger seat assembly to the luggage rack assembly to support a passenger of the motorcycle. | 01-01-2009 |

| 20090074589 | Cooling Circuit for Enhancing Turbine Performance - In a gas turbine having a compressor discharge casing, a cooling circuit diverts compressor discharge air toward a high pressure packing (HPP) circuit. The cooling circuit includes an inlet pipe that receives compressor discharge air. One or several cooled cooling air pipes are in fluid communication with the inlet pipe via a pipe manifold, which distributes the discharge air across the cooled cooling air pipes. A seal is disposed upstream of an entrance to the HPP circuit to limit flow into the HPP circuit, and a second seal is disposed downstream of the HPP circuit at turbine wheelspace to limit ingestion and thus the purge flow air required. The circuit serves to reduce required purge flow in the HPP circuit so that an amount of compressor discharge air can be put back to the main flow path, thereby improving turbine performance. | 03-19-2009 |
| 20110038708 | TURBINE ENDWALL COOLING ARRANGEMENT - An airfoil is provided and includes an airfoil body having a pressure surface extendable between radial ends and a fluid path in an airfoil interior defined therein. The pressure surface is formed to further define a passage by which coolant is deliverable from the fluid path in the airfoil interior, in a perimetric direction from the pressure surface for the purpose of cooling a portion on the surface of the radial end. | 02-17-2011 |
| 20120073304 | TURBOMACHINE INCLUDING A CERAMIC MATRIX COMPOSITE (CMC) BRIDGE - A turbomachine includes a turbine section including a turbine inlet. A transition piece includes a transition piece inlet and a transition piece outlet. A ceramic matrix composite (CMC) bridge member links the transition piece outlet and the turbine inlet. | 03-29-2012 |

| 20120110778 | VACUUM CLEANER WITH HAIR COLLECTION ELEMENT - A vacuum cleaner comprises a hair collection assembly having a hair collection element adapted to collection hair from a surface to be cleaned. The hair collection element is configured to collect hair on the surface to be cleaned substantially only when the cleaning head is moved in a first direction and substantially not when the cleaning head is moved in a second direction. | 05-10-2012 |
