Patent number: 9452592Abstract: The present invention is directed to a multilayer film having an active oxygen barrier layer that comprises an oxygen scavenging composition that is a blend of a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain, a transition metal salt (B), and an oxygen barrier polymer (C) having oxygen barrier properties that can be further enhanced by exposing the composition to a source of ionizing radiation e.g., electron beam radiation. Irradiation improves the oxygen scavenging abilities of the oxygen scavenging composition so that oxygen can be intercepted and scavenged as it passes through the film. The resulting irradiated multilayer film has improved active barrier properties in comparison to the same film prior to irradiation. As result, the multilayer film of the present invention can be used in packaging applications to help maintain a low oxygen atmosphere in the interior of a package.Type: GrantFiled: August 28, 2007Date of Patent: September 27, 2016Assignee: Cryovac, Inc.Inventors: Scott Beckwith, Frank Bryan Edwards, Janet Rivett, Cynthia Louise Ebner, Thomas Kennedy, Rachel McDowell, Drew V.

Patent number: 9335187Abstract: Pressure indicator pressure sensitive adhesive may contain microspheres that burst and release indicator when subjected to pressure and thereby produce a detectable indication of how much pressure has been applied when forming an adhesive joint between opposing structures. Electronic device structures can be assembled using the pressure indicator pressure sensitive adhesive. A camera or other sensor may monitor joint formation. The camera can gather infrared image data, visible light image data, or ultraviolet light image data. Sensor data such as magnetic or ultrasonic sensor data can also be collected on an adhesive joint. Joint inspection can be performed on test structures and production structures and corresponding adjustments made to the joint formation process. Positioners and other equipment that compresses the pressure indicator pressure sensitive adhesive can be adjusted in real time or calibrated using information about the condition of the pressure indicator pressure sensitive adhesive.Type: GrantFiled: November 16, 2012Date of Patent: May 10, 2016Assignee: Apple Inc.Inventors: Stephen R.
