  • Method of making thermocouple
    Patent number: 4121749
    Abstract: A thermocouple assembly is provided wherein dissimilar metals are joined at a hot junction within a protective annular shield transparent to radiation. The hot junction is formed in situ so as to be in intimate contact with the ID of said shield. When the assembly is mounted on a phase change cup, one of the dissimilar metals is insulated from the cup.

  • Device for collecting samples of molten metals
    Patent number: 4120204
    Abstract: The entrance on a sampling device for molten metal is defined in part by a tube made from a deoxidizing agent such as aluminum. The tube melts as a sample of molten bath passes therethrough to a collecting chamber so that all portions of the sample are deoxidized uniformly.

  • Composite high temperature protection tube
    Patent number: 4093193
    Abstract: The composite tube has an inner core of a first material, an intermediate zone of a second material surrounding said core, and an outer wrap surrounding and confining said intermediate zone. The intermediate zone is spirally wound layers of ceramic paper bonded together. The tube is light in weight and has a very low thermal conductivity.

  • Molten metal sample cup containing blob for promoting carbide formation
    Patent number: 4059996
    Abstract: A molten metal sample cup is provided with temperature sensing means to detect phase change in the metal within the cup as a metal sample solidifies. A blob of material which promotes the formation carbides is attached to the inside of the cup to contact the molten metal therein. The blob material comprises a carbide stabilizer selected from the group consisting of bismuth, boron, cerium, lead, magnesium and tellurium, a refractory material and a hydrogen evolving material.

  • Disposable phase change device
    Patent number: 3946594
    Abstract: A disposable phase change device for sensing the rate of cooling of molten metal includes a body having a shallow elongated cavity on its upper surface. Sensing means extend across the cavity and is supported by first and second oppositely disposed walls on the body. The sensing means includes contacts adjacent opposite ends of the body. The upper surface of the body has one or more overflow cavities.
