US Patent:

20060287409, Dec 21, 2006
Filed:

Jun 21, 2005
Appl. No.:

11/157225
Inventors:

Nafih Mekhilef - King of Prussia PA, US
Ramin Amin-Sanayei - Collegeville PA, US
International Classification:

C08J 3/28
US Classification:

522150000
Abstract:

Ionized irradiation can be used to improve the properties of fluoropolymers. In particular, elasticity, strain hardening, and melt strength of a fluoropolymer can be increased by LIP to an order of magnitude by exposure to controlled amounts of radiation; while polymer foams may be thermoformed and crosslinked by irradiation to provide a solvent resistance polymer foams having wide range of densities with good mechanical integrity at elevated temperature

US Patent:

20120062896, Mar 15, 2012
Filed:

Aug 25, 2011
Appl. No.:

13/217519
Inventors:

Aziz Mahfoud Familia - Shrewsbury MA, US
David S. Shackleford - Framingham MA, US
Nafih Mekhilef - Northborough MA, US
Mike A. Zimmerman - North Andover MA, US
International Classification:

G01N 21/59
US Classification:

356437, 356436
Abstract:

The present invention is directed to systems and methods which utilize a cavity ring-down spectroscopy (CRDS) technique implemented for the measurements of vapor transmission rate. In one embodiment, the vapor content to be measured is contained within an optical cavity. Light is then injected into the cavity up to a threshold level and the delay time of the injected light is measured. When the wavelength of the injected light is resonant with an absorption feature of the vapor the decay time increases linearly as a function of vapor content. In this manner, vapor content causes a longer delay time and thus the amount of vapor passing through the film (film permeation rate) can be determined in real-time.

Arnaud Verger - Paris, FR
Margaux Ningre-Coirier - Suresnes, FR
Nafih Mekhilef - Shrewsbury MA, US
Eustache Danysz - Avignon, FR
Christian Murphy - Worcester MA, US
International Classification:

F01D 9/04
Abstract:

Systems and methods include providing a stator vane bushing for a variable stator vane assembly having a movable stator vane and a stator vane housing disposed annularly about the movable stator vane. The bushing includes a flange, a barrel extending from the flange, and a central aperture extending through the flange and the barrel and is disposed in the housing and annularly about the stator vane. The bushing is formed from a ceramic material having a coefficient of thermal expansion (CTE) lower than or equal to a CTE of one or more of a stator vane and a housing of the variable stator vane assembly.
