A sample encapsulation system includes a fixture, a base, a chamber having an inlet and a chamber housing. The housing has inner and outer housings. The chamber is mounted in the inner housing. The base, chamber and housing are affixed to one another and movable in the fixture. A cap has a first ram operably mounted thereto for engaging the chamber inlet. A second ram in the chamber opposite the inlet moves toward and away from the first ram. A heating assembly is positioned in the inner housing and a cooling assembly including a cooling jacket defined in part by the inner and outer housings includes a manifold. The chamber, housing and base are movable toward and away from the cap for engaging and disengaging the first ram with the chamber during and after the encapsulation cycle, respectively. The cooling system includes a vacuum breaker to self-drain following cooling.

The present invention relates to a waterless system and method for cooling a metallurgical processing furnace. Supercritical carbon dioxide (sCO.sub.2) is used as a coolant, as opposed to water, which provides several advantages. For example, sCO.sub.2 can be used at higher temperatures, the risk of an explosion (with use of water) is eliminated, there are no problems with regard to reverse solubility of water at higher temperatures that can foul passageways, and smaller cooling passages can be used thus reducing the cost of cooling panels. A system is disclosed which uses a reservoir to store the sCO.sub.2, a compressor or pump to cause the delivery of the sCO.sub.2 to cooling passages in the furnace, a pressure reducing valve or a turbine to decrease the pressure of the sCO.sub.2, and a heat exchanger to cool the sCO.sub.2 to a liquid state as the sCO.sub.2 travels back to the reservoir.

The present invention relates to a float-glass manufacturing apparatus including a float bath and a heat treatment furnace, in which the heat treatment furnace includes: a dross box including a plurality of lift-out rolls; an annealing furnace including a plurality of lehr rolls; a first partitioning part; a second partitioning part; a gas ejection nozzle; and a guide member.

A water cooled box to be installed in the side wall of a metal making furnace to hold and protect implements such as a burner, a lance, or a material (i.e., carbon or lime) injection device. The box preferably comprises a copper outer shell and a steel inner shell liner welded together, whereby a chamber is formed through which cooling water passes. The box further comprises an inlet and outlet for the water flow and a plurality of conduit passages between the copper and steel shells for mounting the aforementioned implements. The copper shell has bars or slots for slag retention and the steel shell has means for mounting the box into the furnace wall. The copper shell is formed into a curved U-shape for preventing cracking due to thermal mechanical stress and to raise the natural frequency of the panel to resist vibration which can also cause cracking.
