Publication number: 20220143688Abstract: An electromagnetic device for pumping, circulating or transferring non-ferrous molten metal has a duct made of a refractory material with a first aperture at a first end of the duct and a second aperture at a second end of the duct. The duct conveys a body of non-ferrous molten metal between the first and second apertures. The duct encloses the body of non-ferrous molten metal between the first and second apertures. The duct has opposing first and second external side surfaces. A first inductor assembly extends adjacent to the first side surface. The first inductor assembly comprises a plurality of inductors arranged along a length of the duct adjacent to the first side surface. An electronic circuit generates direct current pulses that energise each inductor of the plurality of inductors in a sequence, so as to generate a moving magnetic field within the body of non-ferrous molten metal which propels the body of non-ferrous molten metal along the duct.Type: ApplicationFiled: March 11, 2020Publication date: May 12, 2022Inventors: Paul BOSWORTH, Robert FRITZSCH, Jason MIDGLEY

Patent number: 10739074Abstract: A circulating apparatus for circulating the body of molten metal within an associated furnace is provided. The circulating apparatus includes a molded body with an inlet and an outlet. The inlet and the outlet are aligned with corresponding openings on the associated furnace. The inlet and the outlet define a flow chamber within the molded body. An inductor is secured to a portion of the molded body. The inductor is configured to pump molten metal from the associated furnace and into the flow chamber. A flow channel is spaced from the inlet and the outlet on the molded body. A dam assembly is positioned adjacent the outlet. The dam assembly is movable between a raised position and a lowered position relative to the outlet. The molten fluid flows back into the associated furnace when the dam assembly is in the raised position and the molten fluid flows to the flow channel when the dam assembly is in the lowered position.Type: GrantFiled: July 22, 2016Date of Patent: August 11, 2020Assignee: PYROTEK, INC.Inventors: Paul Bosworth, Jason Dennis Midgely

Patent number: 10215495Abstract: A metallurgical apparatus comprises a vessel for holding a body of liquid metal and a circulating apparatus for circulating the body of liquid metal within the vessel. The vessel has a peripheral wall and a base, and the circulating apparatus comprises a launder that provides an open-topped flow channel and a pumping device for pumping liquid metal through the launder. The launder has an inlet end connected to a first opening in the peripheral wall and an outlet end connected to a second opening in the peripheral wall. The pumping device is configured to pump liquid metal through the launder so that liquid metal flows out of the vessel through the first opening and into the vessel through the second opening, thereby causing the body of liquid metal within the vessel to circulate.Type: GrantFiled: June 17, 2014Date of Patent: February 26, 2019Assignee: PYROTEK, INC.Inventors: Paul Bosworth, Jason Dennis Midgley

Patent number: 9476644Abstract: In accordance with one aspect of an exemplary embodiment, a furnace including a charge well is provided. The charge well comprises an open top chamber including side and base walls of a heat resistant material. An inlet is provided in a side wall of the chamber for receiving molten metal. A ramp is provided adjacent the side wall and an inner wall forms a central cavity. The ramp is disposed between the inner wall and the side wall. The ramp is generally inclined from an intersection with the base wall to adjacent a top surface of the inner wall. The cavity is in fluid communication with an outlet. A passage in the inner wall provides fluid communication between the inlet and the cavity. The inlet and an outlet each receives a conduit and at least one of the conduits can include an elbow joint.Type: GrantFiled: July 9, 2012Date of Patent: October 25, 2016Assignee: PYROTEK INC.Inventors: Roger Howitt, Jim Grayson, Mark Bolton, Paul Bosworth

Patent number: 6574730Abstract: An authentication system of a terminal on a public switched telephone network provides a security node associated with a local exchange and a network terminal. For one-way authentication, the terminal responds to a call initiation by sending a unique authentication code comprising a number and a secret key encrypted according to a first algorithm, the secret key being specific to the terminal. The security node constructs the expected authentication code from the number, using the first algorithm and a second key which is a function of a terminal identification number, and compares the expected code with the received code. In two-way authentication, the security node responds to the call initiation by sending a transaction number to the terminal encrypted according to a second algorithm. The terminal generates the authentication code as a function of the first algorithm, the secret key and the transaction number. The authentication code is sent back to the security node.Type: GrantFiled: February 11, 1997Date of Patent: June 3, 2003Assignee: British Telecommunications plcInventors: Robert Andrew Bissell, Kevin Paul Bosworth, Michael John Britnell, Peter Maxwell Harding, Richard Middleton Hicks, Jonathan James Kingan, Michael Victor Meyerstein, Keith Eric Nolde, John Rabson, Jonathan Crispin Ranger, David Anthony Roberts, Mark Jonathan Stirland, Richard Paul Swale
