  • Patent number: 6447683
    Abstract: A method of treating a waste stream comprising feeding a waste stream into a reactor constructed and arranged for a fast start and maintained in a thermophilic temperature regime of between about 50° C. and 62° C. for a HRT of less than or equal to 48 hours, wherein the reactor contents are maintained at a pH less than or equal to 6.5; drawing a portion of the contents of the reactor and feeding the drawn contents into a second reactor which is maintained in a mesophilic temperature regime of between about 28° C. to 38° C. for a HRT of at least thirteen days; and replacing the contents drawn from the first reactor with more waste from the waste stream. Alternately, the waste stream may be initially treated in a mesophilic reactor, followed by treatment in a thermophilic reactor, or a single stage thermophilic reactor may be used.

  • Patent number: 5804573
    Abstract: Pharmaceutically active derivatives of vitamin D.sub.2 and vitamin D.sub.3 in a solid state composition are stabilized by the presence of effective amounts of pharmaceutically acceptable antioxidant and polyoxyalkyl stabilizer. Specified antioxidants are butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), vitamin E, propyl gallate, .beta.-carotene and ascorbic acid, while specified stabilizers are polyethyleneglycols, polyethyleneglycol ethers, polyethyleneglycol esters, polyoxyethylated castor oil, polyoxyethylated hydrogenated castor oil, polyoxyethylated sorbitan fatty acid esters and polyoxyethylated glycerol fatty acid esters. Suitable proportions of these ingredients by weight lie within the ranges 0.00003 to 0.8 vitamin D.sub.2 or D.sub.3 derivative: 0.01 to 0.1 antioxidant: 0.03 to 30 polyoxyalkyl stabilizer. Compared with similar non-stabilized compositions, the inventive compositions are particularly stable at elevated temperatures and/or humidities.

  • Patent number: 5796743
    Abstract: In a digital television signal processing system, a special codeword, a Packet Alignment Flag (PAF), is inserted into an MPEG codeword bitstream to signify the presence of a Group of Pictures (GOP). The PAF immediately precedes a Picture Start codeword for an "I" frame, which initiates a GOP. A data packet under construction when a PAF appears is terminated since a GOP is intended to begin at a packet boundary. Such termination may result in an abbreviated packet of MPEG codewords less than a prescribed number of bits needed to complete a data packet. The last word of each packet is designated as such to facilitate the subsequent combining of data packets with respective headers. An incomplete data packet is filled with null (zeroed bits) words to make up a complete data packet with a prescribed number of bits.
