Patent number: 10407750Abstract: The invention relates to a method for producing a high-strength ferritic austenitic duplex stainless steel with the TRIP (Transformation induced plasticity) effect with deformation. After the heat treatment on the temperature range of 950-1150° C. in order to have high tensile strength level of at least 1000 MPa with retained formability the ferritic austenitic duplex stainless steel is deformed with a reduction degree of at least 10%, preferably at least 20% so that with a reduction degree of 20% the elongation (A50) is at least 15%.Type: GrantFiled: December 10, 2014Date of Patent: September 10, 2019Assignee: OUTOKUMPU OYJInventors: James Oliver, Jan-Olof Andersson, Erik Schedin

Patent number: 10407746Abstract: The invention relates to a method for manufacturing a ferritic-austenitic stainless steel having good formability, good weldability and high elongation. The stainless steel containing the sum of carbon and nitrogen C+N in the range 0.17-0.295 in weight % in which sum C+N a lower carbon content to avoid sensitisation during welding is compensated by an increased nitrogen content to maintain formability is heat treated so that the microstructure of the stainless steel contains 45-75% austenite in the heat treated condition, the remaining microstructure being ferrite, and the measured Md30 temperature of the stainless steel is adjusted between 0 and 50° C. in order to utilize the transformation induced plasticity (TRIP) for improving the formability of the stainless steel.Type: GrantFiled: April 18, 2012Date of Patent: September 10, 2019Assignee: OUTOKUMPU OYJInventors: James Oliver, Jan Y.

Publication number: 20130344746Abstract: A system and method for connecting a number of network devices together in a daisy chain configuration is disclosed. A connector device comprising a number of cable interfaces for a cable is used to allow a number of network devices connected to a network to be connected in a free-form manner, yet still maintain a daisy chain configuration. A cable comprising at least two conductors, wherein the conductors are preferably a twisted pair of copper wire, is used to connect the network devices, so that each network device only has a single cable connected to it. Additional network devices can be added to the network by simply connecting the additional network device into the existing network with the use of an additional cable and an additional connector device. Wherever the additional network device is added to the existing network, the network will be maintained in a daisy chain configuration.Type: ApplicationFiled: August 21, 2013Publication date: December 26, 2013Applicant: Uponor Innovations ABInventors: Jan Olof Andersson, Kenneth John Lockhart, Trevor Lewis Rossner, Jeffrey Paul Wiedemann, Logan Brent Grauer, Chris Edwin Kasian, William Andrew Perrin, Robert Christopher Kwong, Glenn William Nichols, Jason John Lemon

Patent number: 8588222Abstract: A network device configured to allow the connection of the network device to a network in a daisy chain configuration using a single cable. The network device is connected to a cable with two conductors by a socket that is adapted to receive a plug connected to the end of the cable. When the plug on the end of a cable is inserted into the socket, a first conductor in the cable is connected to an input port of a network component and a second conductor of the cable is connected to an output port of a network component. A signal from the network is transmitted down a first conductor in a cable to a network device and the signal is then transmitted back from the network device down a second conductor in the same cable.Type: GrantFiled: March 29, 2012Date of Patent: November 19, 2013Assignee: Uponor Innovation ABInventors: Jan Olof Andersson, Kenneth John Lockhart, Trevor Lewis Rossner, Jeffery Paul Wiedemann, Logan Brent Grauer, Chris Edwin Kasian, William Andrew Perrin, Robert Christopher Kwong, Glenn William Nichols, Jason John Lemon
