摘要： The present invention is an improved gasket for use in a wide variety of sealing applications. The gasket comprises a continuous, form-in-place gasket element, comprising layers of expanded polytetrafluoroethylene, that has significant tensile strength in both the longitudinal and the transverse directions. As such, the gasketing element of the present invention provides all of the operational advantages of PTFE, while being dimensionally stable, resistant to creep relaxation and providing form-in-place dimensions, thus satisfying a wider range of sealing applications than conventional sealing materials.

摘要： In a communication unit (105) in which a priority scan occurs, wherein priority scan comprises automatically scanning, while the communication unit (105) is unmuted to a non-priority communication resource having a first frequency, at least one priority communication resource having a second frequency, a method of scanning using resource analysis comprises the steps of receiving (301) a signal on the non-priority communication resource and unmuting the communication unit in response to the signal. It is determined (307) if the first frequency is substantially identical to the second frequency. If the first frequency is substantially identical to the second frequency, the priority scan is inhibited (311).

摘要： The article together with the alumina core in situ is placed in a sealable vessel containing a concentrated aqueous potassium hydroxide leaching liquor at a temperature immediately below its normal atmospheric boiling point. The vessel is sealed and the pressure within the vessel is reduced to less than atmospheric pressure so as to induce boiling and agitation of the leaching liquor within the passage in the article. The pressure in the vessel is raised to atmospheric pressure and finally spent leaching liquor together with leached alumina core is removed from within the article.

摘要： A ceramic material for making ceramic moulds and core for metal casting is described comprising basically granular or bubble refractory material, e.g. alumina or mullite, bound together by hardened ceramic slurry. Moulds for lost wax casting are built-up by dipping a wax pattern in ceramic slurry and then applying granules of bubble alumina in an all over coating. A plurality of such coats may be applied by allowing the slurry to harden between applications. The moulds are more insulating than those using tubular alumina grits, for example, and produce castings with smoother surface finishes.

摘要： The present invention provides a method for manufacturing a thin-walled ceramic casting mould which is particularly suitable for casting directionally solidified articles in which rapid cooling of the cast material is required. The mould is transfer moulded around a disposable pattern material and includes an integral core. The mould has an outer wall thickness of the order of 0.5 mm to 2.0 mm. The mould and core may be made of the same or different ceramic materials chosen for their strength or thermal conductivity. The method further provides for a series of high temperature disposable supports embedded in the disposable pattern material, providing support for the outer wall of the mould during the firing process. The disposable supports are disposed of at a temperature at which the mould has acquired self-supporting strength.

摘要： A method of removing refractory material from a component comprises contacting the refractory material with a chemically active agent whereby to convert the refractory material to a more easily removable substance, and removing the more easily removable substance. The method enables alumina cores defining cooling passages in cast blades for use in gas turbine engines to be removed at practically useful rates.

摘要： A reinforced tubular core for casting gas turbine engine blades with cooling air passages therein is disclosed. A method of casting is also disclosed in which the blades are directionally solidified to produce columnar grained or single crystal blades and in which non-linear passages can be produced. The problem in producing such articles is that the moulds and cores used in the casting process are held at temperatures in excess of 1500.degree. for long periods and presently used silica cores deform during the process. Stronger cores of alumina or silicon nitride cannot be easily bent were believed to be non-leachable from the casting. The present invention provides a core having a tubular silica sheath with a solid alumina rod inside it for support. The sheath can be bent and the straight alumina rods can be inserted from opposite ends of the sheath.
