20100171484 | TEST INSTALLATION WITH A TEST BENCH AND METHOD FOR USING SUCH A TEST BENCH IN SAID INSTALLATION - A test installation provides for producing a residence that has a dwelling on the one hand and a test laboratory on the other. The dwelling and the laboratory are electrically powered by separate electric power supplies. The dwelling and the residence are linked to one another by sets of channels passing through a slab of the residence and opening to abutting cable trunks opposite the test laboratory. It is shown that in this way, connections joining measuring apparatus with apparatus for processing the measurements located in the test laboratory can be placed in these channels and this cable trunk. In this way, these connections are always placed correctly at the same location and do not interfere in the measurement. To increase the efficacy of the system, it is provided that a test bench is produced that is independently powered by an electrical perturbation signal that has been measured previously in the dwelling. | 07-08-2010 |

20090212166 | VTOL/STOL TILT-PROP FLYING WING - An aircraft comprises two wings, a fuselage, a tail planform and a pair of counter-rotating propellers. The two wings are located at a longitudinal center of gravity of the aircraft. The fuselage is located forward of the longitudinal center of gravity and coupled to the two wings. The tail planform is coupled to the two wings and located aft of the longitudinal center of gravity. The pair of counter-rotating propellers are located at the longitudinal center of gravity and between the wings. Further, the pair are coupled to a tilting mechanism for tilting the propellers between a vertical flight position and a forward flight position. One of the propellers located beneath the wings when in the vertical flight position and one of the propellers is located above the wings when in the vertical flight position. | 08-27-2009 |
