20100163174 | PROCESS AND APPARATUS FOR PRODUCING COMPOSITE STRUCTURES - A process and apparatus for producing perforated composite structures, such as acoustic skins suitable for aircraft engine nacelle components. The process includes placing at least one mat member, a non-impregnated fabric member, and a pad member on a tool surface so that pins disposed on the mat member project through the fabric member to define holes therein, the fabric member is between the mat and pad members, and the mat, fabric and pad members yield a non-impregnated stack that conforms to the tool surface. The fabric member is then infused with a resin to yield a resin-impregnated fabric and the resin within the resin-impregnated fabric is partially cured, after which the partially-cured resin-impregnated fabric is removed from the tool surface and from between the mat and pad members. A post cure of the partially-cured resin-impregnated fabric can then be performed to yield the composite structure with the holes. | 07-01-2010 |
20130284822 | THRUST REVERSER ASSEMBLY AND METHOD OF OPERATION - A thrust reverser assembly and operation suitable for high-bypass turbofan engines. The thrust reverser assembly includes a translating cowl mounted to a nacelle of an engine and adapted to translate in an aft direction of the engine. The translating cowl has a radially inner wall that defines a radially outer flow surface of a bypass duct of the engine. The thrust reverser assembly includes blocker doors axially guided adjacent first ends thereof by a fixed structure and pivotally and slidably connected along lengths thereof to the inner wall of the translating cowl so that translation of the translating cowl in the aft direction causes each blocker door to move from a stowed position to a deployed position as a result of the blocker door sliding at its first end relative to the fixed structure and sliding along its length relative to the inner wall of the translating cowl. | 10-31-2013 |

20100318867 | APPARATUS AND METHOD TO READ INFORMATION FROM AN INFORMATION STORAGE MEDIUM - A method and apparatus to read information from an information storage medium using a read channel, where that read channel includes a data cache. The invention generates an analog waveform comprising the information, and provides that analog waveform to a read channel, and generates a digital signal from that analog waveform using one or more first operating parameters. The method error corrects that digital signal at an actual error correction rate, and determines if the actual error correction rate is greater than an error correction rate threshold. If the actual error correction rate exceeds the error correction rate threshold, then the method captures the digital signal, stores that captured data in a data cache, reads that digital signal from the cache, generates one or more second operating parameters, and provides those one or more second operating parameters to the read channel. Thereafter, the method uses those one or more second operating parameters to read the information from the information storage medium. | 12-16-2010 |
