The seal includes an inner wall and webs attached to the inner wall and extending transversely there-from. The inner wall and the webs extend circumferentially at least partially around a bypass duct of the turbofan engine. An inner surface of the inner wall interfaces with the VAFN when the VAFN is in the stowed position. The seal is compressed between the VAFN and the seal retainer when the VAFN is in the stowed position. And each of the webs is deformed into a non-planar configuration when the VAFN is in the stowed position.Type: ApplicationFiled: December 29, 2011Publication date: July 4, 2013Applicant: Rohr, Inc.Inventor: Timothy Kent Gormley

Patent number: 8449275Abstract: A pump apparatus includes a first rotor drive mechanism configured to transfer rotation of an input shaft portion to an output shaft portion coupled to an external screw type rotor of a uniaxial eccentric screw pump, the input shaft portion being rotated with a central axis thereof kept in a certain position, and a uniaxial eccentric screw pump. The output shaft portion is rotatably provided via a bearing at a position eccentrically located with respect to the input shaft portion. The rotation of the input shaft portion is transferred through a first power transmission mechanism, including an inner gear, to the output shaft portion to cause the output shaft portion to carry out an eccentric rotational movement. The input shaft portion and the output shaft portion are arranged inside a pitch circle of the inner gear.Type: GrantFiled: January 29, 2008Date of Patent: May 28, 2013Assignee: Heishin Sobi Kabushiki KaishaInventors: Teruaki Akamatsu, Mikio Yamashita, Nobuhisa Suhara

Patent number: 8424398Abstract: A tight package sensor seal includes a first seal portion engaging an outer surface of a sensor body and including a stop surface floatingly engaging a peripheral face surrounding a bore in a cover member. The first seal portion includes a reinforcing insert disposed therein. A second seal portion is axially spaced from the first seal portion and a flexible membrane extends axially between the first and second seal portions. The second seal portion engages an inner diameter of a bore in a cover member and includes a reinforcing insert therein. The sensor seal takes up a small radial space yet allows for radial offset of the sensor body relative to the bore of the cover member.Type: GrantFiled: August 20, 2010Date of Patent: April 23, 2013Assignee: Freudenberg-NOK General PartnershipInventors: John B. Wagner, Kane A. Myers, J. Brian Cloud

Publication number: 20130014519Abstract: A frozen beverage device to convert a liquid beverage into a semi-frozen or frozen form has inner and outer walls forming a refrigerant cavity containing a refrigerant material with a freezing point below the freezing point of the liquid, the refrigerant material occupying at least 80% of the volume of the refrigerant cavity. The outer wall has a base portion which can be moved from a first position, where the liquid is at least semi-frozen, to a second position where the internal pressure in the refrigerant cavity urges the inner wall outwardly towards the outer wall so that the refrigerant material contacts a maximum area of the surface of the inner wall in the refrigerant cavity for maximum heat transfer and to minimise constriction of access to the frozen beverage. Alternative methods to seal the inner and outer walls to close the refrigerant cavity are also disclosed.Type: ApplicationFiled: February 22, 2012Publication date: January 17, 2013Applicant: HYDRO-TURBINE DEVELOPMENTS PTY LTDInventor: Alfio Bucceri
