摘要:
A method is provided for analyzing samples of metal melts, wherein a sample is taken from a metal melt using a sampler having a sample chamber and which is constructed as an immersion lance. The method includes transporting the sample from the sampler through a transport conduit to the sphere of action of an analytical device, and analyzing the sample there using the analytical device.

A pouring nozzle is provided for use in a container for metal melts. The pouring nozzle has an inner wall surrounding a through-flow opening for metal melts and an outer housing. During operation of the pouring nozzle a pressure of at maximum 500 mbar exists between the inner wall and the outer housing.

A method is provided for measuring the cooling curve of melts and/or the heating curve of melt samples with an optical fiber, wherein an immersion end of the optical fiber having an at least partially free surface is surrounded with a spacing by a temperature-resistant sample-receiving chamber. The optical fiber is immersed with its immersion end in the melt, and a sample is thereby formed in the sample-receiving chamber. The sample-receiving chamber with the sample and the optical fiber are thereafter pulled out of the molten metal. The cooling curve of the sample and/or, after previous solidification of the sample, the temperature profile during heating is measured with reference to a signal obtained by the optical fiber and forwarded to a measurement device. In addition, a corresponding device is provided for the measuring method.

An article includes an object and a sealing member. The object includes a cavity formed therein. The sealing member includes sealant and a carrier to which the sealant is attached. At least one of the carrier and the object includes attachment means whereby the carrier is configured to be attached to the object such that at least a portion of the sealant is retained within the cavity.

A cable closure is provided with at least two housing parts which, in use, are brought together, and when brought together provide a cavity for containing sealing material, through which one or more cables may extend into the closure. The cable closure also includes a sealing material which is contained in the cavity upon bringing the housing parts together, and, which seals between the cable (s) and the housing part(s); and at least one resilient member which, in use, is contained in the cavity. When the housing parts are brought together, in use, the resilient member is compressed, and thus causes the resilient member, by its resilience, to apply a compressive force to the sealing material.

A method is provided for measuring a parameter of a molten metal bath by an optical fiber surrounded by a cover. The optical fiber is immersed in the molten bath, and the radiation absorbed by the optical fiber in the molten bath is fed to a detector, wherein the optical fiber is heated when immersed in the molten bath. The heating curve of the optical fiber has at least one point P(t0, T0), wherein the increase ΔT1 in the temperature T of the optical fiber over the time Δt in a first time interval t0−Δt up to the temperature T0 is smaller than the increase ΔT2 in the temperature of the optical fiber over the time Δt in an immediately following second time interval t0+Δt.

A seal is provided for sealing an aperture in an object through which aperture one or more elongate articles extends. The seal includes a first support member having at least one longitudinally extending channel adapted to accommodate and support an elongate article. A second support member is longitudinally spaced from the first support member. The second support member has at least one longitudinally extending channel corresponding to that of the first support member and a sealing member is positioned between the first and second support members. An elongate article may thus be accommodated within the longitudinal extending channel of the first support member so as to extend through the corresponding channel on the second support member while deforming sealing member.
