Publication number: 20180137501Abstract: Embodiments of the invention are directed to a system, method, or computer program product for manipulating and distributing electronic resources. The system accepts a request from a user for a transfer of an electronic resource to a second user and in response, generates a transfer vehicle containing details of the transfer. The transfer of electronic resources is directed and completed through the transmission of the generated transfer vehicle to a device associated with the second user. As only the transfer vehicle is transmitted without the need for additional personal identifying information, a transfer of electronic resources may be completed securely and relatively anonymously in a time frame comparable to that of an exchange of a traditionally used physical resource.Type: ApplicationFiled: December 13, 2016Publication date: May 17, 2018Inventors: Kevin Patrick Condon, Robert Scott Seidman, Robert S.

Patent number: 7442443Abstract: Disclosed is a chromium-nickel stainless steel alloy article having an adherent, wear resistant coating of metallic oxides and a method of forming an adherent, wear resistant coating of metallic oxides on a chromium-nickel stainless steel alloy article. The coating desirably has a thickness of from about 25.4 to about 102 microns (1 mil to about 4 mils) and is formed by exposure of the article to an oxidizing atmosphere, preferably air, preferably during heat treatment of the article. Such articles are useful, inter alia, as torque drive inserts for a friction disk for a multi-disk brake or clutch assembly. The drive inserts can be formed of an alloy such as 17-4PH stainless steel alloy having an adherent coating of lubricious oxides formed during frictional contact. It is believed that these lubricious oxides will form also if the heat treated base alloy is subject to temperatures greater than 815.6° C. (1500° F.) for a sufficient time in an oxidizing atmosphere.Type: GrantFiled: May 31, 2005Date of Patent: October 28, 2008Assignee: Goodrich CorporationInventors: John P. Swank, Leslie Steele, Robert Bianco
