Patent number: 11001903Abstract: In some examples, an apparatus includes a pallet supporting a plurality of workpieces, the pallet including through-holes structured to pass a quenching fluid. In some examples, the apparatus further includes a reservoir of quenching fluid configured to provide the quenching fluid, and a plurality of upturned wall portions extending from the pallet and substantially surrounding the exteriors of the plurality of workpieces. The plurality of upturned wall portions may be located in relative orientation to the plurality of workpieces to regulate heat transfer coefficients of the plurality of workpieces during a quenching operation.Type: GrantFiled: November 8, 2017Date of Patent: May 11, 2021Assignee: Rolls-Royce CorporationInventors: Gangshu Shen, Nathan J. Cooper, Nathan Wesley Ottow, Robert Louis Goetz, John F. Matlik

Patent number: 9689502Abstract: According to one aspect, a rotary exhaust valve system includes an arcuate ring having a first plurality of apertures and a rotary valve ring disposed in an overlapping relation with the arcuate ring. The rotary valve ring has a second plurality of apertures forming therein corresponding to at least some of the first plurality of apertures. A first crank is disposed in a first side of the rotary exhaust valve system, and a second crank is disposed in a second side of the rotary exhaust valve system. The second crank is connected to the first crank and the rotary valve ring, and the first crank actuates the second crank and moves the rotary valve ring such that openings of the first plurality of apertures are closed and opened.Type: GrantFiled: October 26, 2015Date of Patent: June 27, 2017Assignee: Rolls-Royce CorporationInventors: Nathan W. Ottow, Nathan J. Cooper
