Patent number: 5103858Abstract: A valve for an extraction device of a molten metal or molten alloy atomizing chamber comprises a valve member which is rotatably mounted in a pipe. The peripheral edge of the valve member has a groove in which is located a rubber seal. A protecting member is located in the pipe upstream of the valve member with respect to the flow of an atomizing gas and metal particles through the pipe. The protecting member is positioned such that when the valve member is in the open position the protecting member is immediately upstream of the peripheral edge of the valve member to prevent metal particles impinging upon and wearing the rubber seal. The protecting member is also supplied with cooling gas and is arranged to direct the cooling gas through passages over the surfaces of the valve member to prevent the seal overheating.Type: GrantFiled: April 29, 1991Date of Patent: April 14, 1992Assignee: Rolls-Royce plcInventor: Ian A.

Patent number: 4642867Abstract: An apparatus for use in the manufacture of brush seals which comprise a plurality of filaments of brush material sandwiched between two sideplates. The apparatus comprises a workplate onto which is mounted one of the sideplates of the seal. A plurality of first clamping members clamp against the sideplate. Each member can be lifted to enable a tuft of brush material to be inserted and clamped against the sideplate. To enable more than one layer of tufts to be built up on the sideplate a second clamping means is provided to enable the first clamping members to be released. An indexing mechanism allows the first clamping members to be moved relative to the clamped tufts and when the assembly of tufts is complete a second sideplate is clamped onto the tufts and first sideplate. The apparatus also includes means for cutting a prewound ribbon of adhesively bonded wires into short lengths to form the tufts.Type: GrantFiled: February 7, 1986Date of Patent: February 17, 1987Assignee: Rolls-Royce LimitedInventors: Gerald W. Hough, Ian A. Hunt
