Patent number: 7901763Abstract: Porous infusible polymer (IP) parts are made by incorporating 0.2 to 10 volume percent organic fibers, preferably with short lengths, into the particulate IP, consolidating the mixture under pressure and optionally heating, and then “burning off” the fibers. After the fibers are burned off the resulting part has porosity in which the pores are elongated, usually retaining the shape of the organic fibers. When these parts are exposed to moisture (which they usually absorb) and then suddenly heated they tend not to blister from vaporization of the water. This makes them useful as parts for aircraft (jet) and other engines and other applications where sudden temperature increase may occur.Type: GrantFiled: December 19, 2007Date of Patent: March 8, 2011Assignee: E.I. du Pont de Nemours and CompanyInventor: Thomas P.

Patent number: 7900870Abstract: An aircraft vent door system includes a vent door for a vent on an aircraft door. A cam, having a groove, is disposed on the vent door. The system also includes a movement assembly, which includes a roller disposed within the groove, and a lever coupled to the movement assembly. A portion of the lever extends beyond and proximate to the perimeter of the vent door. A second lever may also be attached to the aircraft door. The first lever pivots in response to the movement of the movement assembly, and urges the second lever to pivot. The second lever, in turn, urges the vent door open, thereby overcoming the sticking effect of, for example, built up ice or other obstructions.Type: GrantFiled: May 9, 2008Date of Patent: March 8, 2011Assignee: B/E Aerospace, Inc.Inventors: Randi Kyle, Sergio Bainotti

Publication number: 20110050331Abstract: A high voltage current source and a voltage expander implemented in a low voltage semiconductor process. The voltage expander extends the operating voltage range of a stack of transistors to multiple times a supply voltage Vdd at the output node of the stack without exceeding the breakdown voltage of any of the transistors in the stack. The voltage expander uses a diode and a voltage divider to detect the output node voltage changes and generates a plurality of voltages that control the gate voltages for the stack of transistors. A high voltage wide swing current source utilizes a transistor to set the output current and the voltage expander to extend the output voltage range of the current setting transistor. An additional transistor and another current source ensure that the output current is constant throughout the entire output voltage range between about 0 V and multiple times the supply voltage Vdd.Type: ApplicationFiled: August 26, 2010Publication date: March 3, 2011Applicant: ALFRED E.
