Abstract: Disclosed herein are compositions and methods relating to rubber compositions, comprising crumb rubber and a maltene-like oil, which provides simultaneous rut, crack, moisture, and temperature resistance in both dense grade and gap grade paving mixtures. Also disclosed are methods of producing the rubber compositions, and methods of using the same.

Abstract: Disclosed are methods for producing rubber-containing bituminous mixtures by pressurizing mixtures of bituminous materials, crumb rubber, and one or more suspension agents with a gas, and then reducing the pressure, creating bubbles of the gas in the mixture. Also disclosed are methods of introducing gas into such mixture by rapid mixing. Mixtures produced by the disclosed methods, such as rubber-containing asphalt mixtures and paving compositions thereof, and their use are also disclosed.

Abstract: Removing PCBs from recycled plastic materials. A reactor can volatilize the PCBs from interior portions of the plastic materials under pressure conditions below atmospheric pressure and temperatures sufficient to melt the plastic material. The reactor typically includes agitation that exposes the plastic material to the atmosphere within the reactor to promote the volatilization of the PCBs.

Abstract: A method and system through which an application program can access textual data through a common text accessing interface. The system provides a hierarchy of interfaces through which various text manipulation functions can be accessed. These functions control the editing and displaying of text. The hierarchy of interfaces include an interface for manipulating a document and for manipulating a range of characters within the document. By using these interfaces, a server can expose its text to various clients.

Abstract: A method and system are disclosed for displaying text in a way that is both aesthetically pleasing and faithful to a printed output. Characters of a document displayed by a visual display in a computerized text processing system are positioned accurately with respect to the positions they would occupy in a printout of the document. During ordinary typing of English-language text, as text is typed beginning at the left margin and proceeding rightward, text to the left of the current cursor position does not move about, and its intercharacter spacing (kerning) is stable. The invention can be adapted for text processing in languages other than English.
