    摘要： An image display device comprising: an image display panel; a heat dispersion material (16) comprising a sheet of compressed particles of exfoliated graphite having an in-plane thermal conductivity of at least about 250 W/m.K positioned proximate to the image display panel; a support member (18) positioned proximate to the heat dispersion material opposite the image display panel, wherein the support member provides a support factor of less than 150 mm.W/m.K and wherein the support factor is determined by multiplying the thickness of the support member by its in-plane thermal conductivity.

    摘要： An improved method of operating an arc furnace is provided. The sidewall of the furnace includes a refractory lining. A charge of scrap metal is added to the furnace. The charge is melted and a slag layer is formed on the top of the melting charge. The furnace is tapped at the bottom to remove a portion of the melted charge. After tapping the furnace, the slag is splashed onto the sidewall to thereby coat the sidewall with a frozen slag layer.

    摘要： A new process for preparing a graphite article such as a graphite electrode or cathode is described. The process comprises (a) mixing (i) a particulate fraction comprising at least about 35 weight percent coke, coal or mixtures thereof having a diameter such that a major fraction passes through a 25 mm mesh screen but not a 0.25 mm mesh screen, and (ii) a pitch binder, to form a stock blend; (b) extruding the stock blend to form a green stock; (c) baking the green stock to form a carbonized stock; and (d) graphitizing the carbonized stock by maintaining the carbonized stock at a temperature of at least about 2500 degree C. A graphite electrode column made using the new process has sufficient strength to maintain the integrity of the graphite electrode column without use of a pin, has increased resistance to cracking and has reduced brittleness, when plural such graphite electrode columns are used to form a graphite electrode.
