Abstract: A sealant useful for sealing the surfaces of carbon foams to provide a surface useful for, inter alia, composite tooling or other high temperature applications or for bonding of carbon foams together to form larger blocks.

Abstract: An induction furnace capable of operation at temperatures of over 3100° C. has a cooling assembly (60), which is selectively mounted to an upper end of the furnace wall (76). The cooling assembly includes a dome (62), which is actively cooled by cooling water coils (68). During the cool-down portion of a furnace run, cooling initially proceeds naturally, by conduction of heat away from the hot zone through a furnace insulation layer (58). Once the temperature within the furnace hot zone (20) reaches about 1500° C., a lifting mechanism (80), mounted to the dome, raises a cap (16) of the furnace slightly, allowing hot gases from the hot zone to mix with cooler gas in the dome. This speeds up cooling of the hot zone, reducing cool-down times significantly, without the need for encumbering the furnace itself with valves or other complex cooling mechanisms which have to be replaced periodically.

Abstract: An interactive breast model (100) is disclosed for training lay persons and health care providers to perform effective breast examinations and to locate and identify masses in a breast. The model of the invention comprises a silicone breast model (102) equipped with a data acquisition unit (106) having a plurality of sensors (1002) for detecting displacement in the surface (202) of the breast model during an examination and data acquisition modules (1004) for receiving the sensor output data. The data acquisition unit (106) sends the sensor output to a personal computer (108) for analysis and display to the user (1018). Software (1006) executing on the personal computer performs fuzzy logic algorithms to correlate the sensor output data to usable information regarding the time duration of the examination, finger placement of the user, and the level of displacement throughout the examination. This performance data (1030) is displayed to the user.

Abstract: A railway terminal having a parking area, an access restriction system adjacent to the parking area and a railroad track adjacent to the parking area. The access restriction system limits access to said parking area. The railroad track includes a first section, a second section and a loading pad, wherein the first and the second sections each accommodate a plurality of intermodal railcars, each railcar designed to transport a truck trailer, wherein the first section is coupled to a main rail line. The loading pad links the first section of the railroad track to the second section of the railroad track. The loading pad is designed to support tractor-trailers.

Abstract: Method for making a component, graphite component, such as a graphite crucible, for use in the production of silicon crystal growth from molten silicon wherein the graphite component has an outer coated layer of glassy carbon formed from a thermoset organic resin that prevents contamination of the molten silicon by carbon from the graphite component.

Abstract: A process for isostatic molding permitting density of the product being molded to be measured and controlled in-situ. The process is carried out by weighing the mold assembly in the fluid medium within the pressure vessel inclusive and exclusive of the powder charge with the latter weight determined by the difference between the weight of the mold assembly outside of the pressure vessel and its buoyant force in the pressure vessel.

Abstract: Highly stereospecific olefin polymers are obtained in enhanced yield in a continuous gas-phase fluid bed process for polymerizing alpha monoolefins employing a catalyst system comprising (a) a solid titanium-containing procatalyst, (b) an organoaluminum activator compound, and (c) a selectivity control agent, by continuously adding dialkylaluminum halide to the reactor during polymerization and conducting polymerization at a temperature of 0.1.degree. to 5.0.degree.

Abstract: A damaged binding post on a telephone wire connecting panel is replaced by a binding post having a threaded stem and a polygonal head adapted to seat freely in a hole in the panel. A retaining nut is screwed on the stem and spaced from the surface of the panel. A bridge is placed over the binding post and each of the next adjacent binding posts and a locking nut is threaded over each of the stems of the adjacent binding posts, to cause the bridge to bow and provide a bias urging the retaining nut downwardly forcing the replacement post to seat in the hole.
