    Abstract: Provided is a glass composition useful in preparing fiberglass, with the composition comprising SiO2 in an amount ranging from 52-62 weight percent: B2O3 in an amount ranging from 3.5-5.5 weight percent; CaO in an amount ranging from 18-25 weight percent; MgO in an amount ranging from 0.5-4 weight percent; Al2O3 in an amount ranging from 10-15 weight percent; and Na2O in an amount ranging from 0.25-2 weight percent. The glass composition has an HTV of no greater than 2300° F. and a liquidus temperature at least 150° F. less than the HTV temperature. The composition allows one to realize costs savings associated with lower batch costs and abatement requirements, without significantly increasing the energy required for melting the glass, reducing fiberization efficiency, or requiring the development of new bushing technology.

    Abstract: Random access to arbitrary images, whether frames or fields, of a video segment compressed using both interframe and intraframe techniques may be enhanced by including state information, for decoding and display, at appropriate points in the compressed bitstream to enable random access to each intraframe compressed image. The state information may be inserted during compression or by processing the bitstream of compressed data. An image index also may be generated that maps each temporal image in a decompressed output image sequence to an offset in the compressed bitstream of the data used to decode the image. The index may be created during compression or by processing the bitstream of compressed data. To access one or more samples starting with a specified point in time in a decompressed output image sequence, the index is accessed using the specified point in time to identify another sample in the decompressed output image sequence for which data is used to produce the specified sample. The identity of the other sample is used to access the index to identify a location in the compressed data for the data used to produce the specified sample.

    Abstract: Methods for waste treatment and compositions of stabilized waste elements are provided, typically for the disposal of arsenical wastes. Arsenic trioxide waste produced as a by-product of metal extraction is slurried in water for from 6 to 24 hours with finely divided quicklime to produce nonvolatile calcium arsenate (III). An excess of CaO stoichiometry with As is used to consume secondary waste species such as sulphate, silicate and iron oxides. The precipitated arsenate is oven dried at 120.degree. C. and then calcined in air between 15 minutes to several hours at 1000.degree. C. to 500.degree. C. respectively to oxidize arsenate (III) to arsenate (V) as Ca.sub.5 (AsO.sub.4).sub.3 (OH) (an apatite) as the major arsenic immobilization phase, with minor arsenic incorporated in Ca.sub.3 (AsO.sub.4).sub.2. Calcium sulphate anhydrate (sulphate immobilization) and calcium iron oxide (iron immobilization) are also produced. Tertiary immobilization is achieved milling or fracturing and incorporating the apatite an encapsulant consisting of ordinary portland cement and flyash. After curing for one month in steel drums in a water saturated atmosphere, the waste form is ready to be transported either to a repository or to used as landfill. Further security may be achieved at the back end of the process by lining the repository with ferric clays that will strongly absorb and adsorb heavy metal species which may escape.
