Publication number: 20160083086Abstract: A rotor yoke manufactured by a process comprising preparing a molded rotor yoke in a closed cavity tool and possibly machining at least one portion of the molded rotor yoke to form the rotor yoke. In the preferred embodiment, the preparing of the molded rotor yoke is accomplished by applying layers of uncured low-flow composite material and a layer of uncured high-flow adhesive; substantially enclosing the uncured molded rotor yoke in the closed cavity tool; and applying pressure so as to compress the uncured molded rotor yoke; and curing the uncured molded rotor yoke. During the curing process, the high-flow adhesive bleeds out of the molded rotor yoke, thereby preventing marcels from forming through movement of the low-flow composite material.Type: ApplicationFiled: December 1, 2015Publication date: March 24, 2016Applicant: TEXTRON INNOVATIONS INC.Inventors: FRANK B. STAMPS, PAT TISDALE, BRYAN MARSHALL, TOM CAMPBELL

Publication number: 20120283656Abstract: The present invention provides fluid and material delivery methods and devices for practicing the methods. In one embodiment the device is a micrometer assisted fluid delivery device comprising a micrometer, a holder portion, and a syringe. The micrometer assisted delivery device is designed to control the amount of the solution that can be aspirated and delivered and the rate at which material is aspirated and dispensed from a syringe into tissue. The invention also provides a method of delivering cellular material comprising injecting the cellular material into a subject such that the injected cells retain their inherent morphologic characteristics upon injection.Type: ApplicationFiled: May 23, 2012Publication date: November 8, 2012Inventors: Terrell Pruitt, Stephen A.

Patent number: 8206335Abstract: The present invention provides fluid and material delivery methods and devices for practicing the methods. The invention provides a method of delivering cellular material comprising injecting the cellular material into a subject such that the injected cells retain their inherent morphologic characteristics upon injection. The method comprises the steps of aspirating the cellular material into a fluid delivery device which incorporates a syringe arrangement. The cellular material is aspirated into the main body of the syringe until the desired amount of a material has filled the syringe body. The needle of the fluid delivery device is then inserted into the skin of a subject at an angle about parallel to the skin until a desired depth has been reached. The cellular material is then injected in the subject until the desired volume of material has been injected. The needle of the device is then rotated approximately 45 to 90 degrees and the needle is removed from the injection site.Type: GrantFiled: July 14, 2010Date of Patent: June 26, 2012Assignee: Aderans Research Institute, Inc.Inventors: Terrell Pruitt, Stephen A.
