Patent number: 10940516Abstract: A sealing device includes a flexible seal (10), a source of gas (15), a gas inlet (14) into the seal, and a gas outlet (17) from the seal 10, 17 whereby gas flows through the seal. A cryogenic source cools the seal and the gas from the cryogen helps seal the seal to the roll and to keep the seal flexible as the gas flows.Type: GrantFiled: November 11, 2015Date of Patent: March 9, 2021Inventor: Michael Trevor Clark

Patent number: 9433985Abstract: A feed roll and stripper assembly for a rolling mill includes at least one feed roll at each of an entry side and an exit side of a pair of work rolls and a stripper at each of the entry and exit side of the pair of work rolls. Each stripper has a stripper tip. At least one of the strippers or feed rolls are adapted to have an adjustable vertical separation from one of the work rolls, according to the direction of movement of material through the work rolls. The vertical separation of the at least one stripper or feed roll from the one work roll on the entry or exit side is different from the vertical separation of the other at least one stripper or the feed roll on the other of the entry or exit side. Each stripper tip is separated from one of the work rolls.Type: GrantFiled: April 11, 2012Date of Patent: September 6, 2016Assignee: Siemens Plc.Inventors: Michael Trevor Clark, Brian Cooper, Stuart Leflay, Philip Round

Patent number: 9358597Abstract: An apparatus for controlled cooling and a control method related to controlled cooling of hot plate or strip shaped metal. The apparatus comprises a header fitted with a first valve which allows air to escape from the header and prevents cooling fluid escaping from the header when being filled and prevents air from getting back into the header. During operation due to the apparatus an improved operation even at low flow rates is possible.Type: GrantFiled: November 19, 2007Date of Patent: June 7, 2016Assignee: SIEMENS PLCInventors: John Edward Beeston, Michael Trevor Clark

Patent number: 9016100Abstract: A fully hydraulic edging system suitable for use in wide plate mills is disclosed. The need for electro-mechanical screws to effect large movements of the side rollers is avoided by employing a pull-back hydraulic cylinder for this purpose. The main hydraulic cylinders are switched to a non-operational mode during large movements thus avoiding the need for large volumes of hydraulic fluid to be transferred under high pressure.Type: GrantFiled: February 9, 2010Date of Patent: April 28, 2015Assignee: Siemens PLCInventors: Michael Trevor Clark, John Franey, Martyn Jones, Andrew Mallison

Publication number: 20140090437Abstract: A roll stripper device includes a stripper mounted on a stripper support, a sensor and a processor in a control system. The sensor is adapted to provide a measurement of a distance to a work roll and the processor is adapted to determine a position of a tip of the stripper relative to the work roll, using the distance provided by the sensor. A method of determining a distance of a stripper from a work roll and a method of controlling a relative position of a stripper and a work roll, are also provided.Type: ApplicationFiled: April 11, 2012Publication date: April 3, 2014Inventors: Michael Trevor Clark, Philip Round

Patent number: 8505426Abstract: A method, and an apparatus, for operating a hydraulic shearing machine. For cutting a shearing-movement of at least one shear blade which is curved, starting from a starting-position under application of an overall actuating-force and for resetting of the shear blades which were moved for cutting to their starting-position after accomplishment of the shearing-movement, a reset-movement under application of an overall reset-force. The shearing-movement and the reset-movement are accomplished by a hydraulic actuating-mechanism comprising hydraulic cylinders, wherein the overall actuating-force and the overall reset-force being applied to the moved shear blades by at least one hydraulic cylinder of the actuating-mechanism. The magnitude of the overall actuating-force is adjustable by switching one or several hydraulic cylinders of the actuating-mechanism in and out of operation-mode.Type: GrantFiled: September 1, 2008Date of Patent: August 13, 2013Assignee: Siemens Vai Metals Technologies Ltd.Inventors: Peter Christoforou, Michael Trevor Clark, David Eastwood, David Stonecliffe, Shaun Tyas

Publication number: 20110259164Abstract: A rolling cut metal shearing apparatus is described in which the starting and, or end position of a shear blade is varied according to the width, position and thickness of material to be cut, thereby optimising the stroke of the blade for the material dimensions. This provides for shorter cutting times, reduced volumes of hydraulic fluid and increased throughput.Type: ApplicationFiled: November 12, 2009Publication date: October 27, 2011Inventors: Michael Trevor Clark, Nick Champion, David Stone Cliffe

Publication number: 20100077823Abstract: Method for thermo-mechanical controlled rolling of metal slabs to plates or strips, in which for two successively rolled slabs the time gap between the starts of their rolling phases 1 is always smaller than the sum of the duration of all rolling phases and all cooling phases of the rolling pattern, and in which during rolling the batch it occurs on at least one rolling mill stand several times that a rolling phase applied to one slab or plate or strip is succeeded by a different rolling phase applied on another slab or plate or strip. In the apparatus for thermo-mechanical rolling according to that method the number of storage positions is half the interleave depth of the performed rolling pattern rounded up to an integer.Type: ApplicationFiled: February 8, 2008Publication date: April 1, 2010Inventors: Nick Champion, Michael Trevor Clark, Birger Schmidt, Michael Mick Steeper
