The invention relates to a rinsing device for asealing system on a housing element. It iscomposed of a sealing surface and anassociated closing element with a radiallyouter elastic seal. The rinsing devicecomprises at least one source for a rinsingmedium, an annular channel disposed in thehousing element, and an annular gap fromwhich the rinsing medium can escape. Whenthe closing element is in the shut position theannular gap is maintained in a closed state bythe radially outer elastic seal. The annularchannel is provided with at least oneadditional closable outlet for the rinsingmedium. At least one side of the annular gapis ‘waved’ or ‘toothed’. The invention furtherrelates to a method for using the rinsingdevice, according to which a rinsing mediumis fed from the source to the annular channeland is drained off via the additional outletwhen the closing element and the annular gapare closed and the additional outlet is open.Patent number: WO 02/27219Inventor: H.-D.

Fluid sealingAssignee: A.W. Chesterton Co, USAA mechanical seal which is designed to bemounted on a stationary housing that contains arotating shaft is described. The seal employs aninboard mounted spacer element to provideaxial and radial spacing between a holder and agland. In addition to providing selected axialand radial spacing, the element also promotes orenhances fluid circulation in a process chamberformed between the gland and holder, byrotating about the shaft.Patent number: WO 02/27197Inventor: H.V. Azibert Publication date: 4 April 2002

Flexible interlocking combustortransition sealAssignee: Siemens Westinghouse PowerCorporation, USAThis patent provides details of a flexible sealassembly which has a seal body, a transitionsection attachment end, and a turbine assemblyattachment end. The seal is structured in such away that it can be attached to both the transitionsection and the power plant turbine assemblywithout the use of fasteners.Patent number: WO 02/27148Inventor: S.M. MoellerPublication date: 4 April 2002

Multi-component chemical system Assignee: BASF Coatings AG, GermanyThis invention relates to a multi-componentsystem that can be hardened by means of heat

and actinic radiation. The system contains atleast one component (comprising at least oneconstituent which has at least one isocyanatereactive functional group and at least onefunctional group having at least one bondwhich can be activated by actinic radiation) inaddition to at least one vinylaromaticallylalcohol copolymer. It also has at least onecomponent that contains at least onepolyisocyanate. The invention also relates tothe use of this system as a sealant, coatingmaterial or adhesive.Patent number: WO 02/26853Inventors: E. Nienhaus, B. LettmannPublication date: 4 April 2002

Fluid control valve Assignee: Fisher Controls International Inc,USAAn improved fluid control valve is provided. Thevalve includes a seal that is captured between anupstream flange adapter and a valve member, sothat the seal prevents fluid from leaking aroundthe valve member. The seal is carried by a holderring, and stop-members are attached to theflange adapter for limiting upstream travel of theholder ring at specific points, thereby restrictingpossible tilting of the seal as the valve memberrotates.Patent number: WO 02/29294Inventors: C.R. Kuhlman, D.G. Blagg, W.D.Smith, L.J. Weber Publication date: 11 April 2002

Determining natural frequencies ofbrush sealsAssignee: General Electric Co, USAA brush seal segment is mounted within apressure vessel and against a surface of anelement to provide a seal between regionslocated on each side of it at different pressures.By vibrating the vessel through a range offrequencies, the natural frequencies of the brushseal (under pressure loading) can be ascertained.Additionally, by adjusting the interferencebetween the surface and the bristle tips, thenatural frequencies of the brush seal undervarious interference loadings can likewise beascertained. The pressure vessel uses mounts toattach it to a shaker table so that it can bevibrated through the range of frequencies.Patent number: WO 02/29292Inventors: M.F. Aksit, M. Demiroglu, H.R.Sarshar, O.S. DincPublication date: 11 April 2002

Corrosion seal for threadedconnectionsAssignee: Grant Prideco LP, USAThe threaded connection between the pin andthe box ends of two pipes is sealed externally and

internally to protect the threads in theconnection from exposure to corrosive fluids.Seals are provided at each axial end of thethreads. The external seals may be formed by ametal-to-metal engagement between the pin andbox, or they may be provided by an annular,elastomeric ring engaging the pin and box of theconnection. A threaded compression ring maybe used to compress the elastomeric seal betweenthe pin and box. The seals protect dynamicallyloaded threaded connections from fatigue-induced failure in corrosive environments.Patent number: WO 02/29290Inventors: R. Delange, E.M. Evans, R.C. Griffin,W.W. Starodub, G.K. Otten, D.S. AndersonPublication date: 11 April 2002

Shaft sealAssignee: Heidelberg Digital LLC, USAThe subject of this patent is a seal for a rotaryshaft. The shaft extends through the wall of acontainer, in which is placed agitated, abrasiveparticulate matter. The seal includes a firstpolymeric member around the shaft (and is inengagement with the wall of the container),with the shaft rotating inside the first member.The first member engages a second polymericmember that is positioned around the shaft.This rotates with the shaft, relative to the firstmember. A third compressible member ispositioned around the shaft for rotation withthe shaft and the second member. A retainingring maintains the first, second and thirdmembers in compression between the retainingring and the wall.Patent number: WO 02/29289Inventors: C.S. Garcia, P.E. Thompson, K.M.Patterson, B.P. PelligraPublication date: 11 April 2002

Expansion seals for concentrictubular structuresAssignee: OBI Corporation, USAAn apparatus and method for sealing a firsttubular member in a fixed position withrespect to a second concentric tubular memberis described in this patent. The inner tubularmember is formed with a shallow annulardepression in the tube wall at the point wherea sealant is placed. This causes the wall of theinner tubular member to intrude into theotherwise cylindrical passage within the tube.On the outer surface of the first tubularmember the depression is filled with a partiallycompressible fluid. The annular depressionand the partially compressible fluid are then covered by a malleable/ductile sleeve.Placement of the seal involves positioning theinner tubular member within the outer tubularone, and moving the inner tube longitudinallyso as to position it at the desired point where
