Abstract: The invention describes families of compounds that utilize multihydroxyl phenyl groups to provide adhesive properties. Selection of the multihydroxy phenyl group along with linkers or linking groups and the linkages between the linkers or linking groups with polyalkylene oxides, provides materials that can be engineered to afford controllable curing time, biodegradation and/or swelling.

Abstract: The invention includes an anaerobic solids digestion apparatus comprising a digester, at least one draft tube; at least one nozzle and a biogas source; a method for digesting a waste stream in an anaerobic solids digestion apparatus comprises feeding a waste stream to a digester; reacting the anaerobically biodegradable material in the waste stream with anaerobic bacteria in the digester; introducing a mixed liquor into the digester and mixing the mixed liquor; and a method for minimizing the use of inhibitory polymers by concurrently digesting and concentrating the mixed liquor in the digester.

Abstract: A phase separator, upflow reactor apparatuses and methods for separating phases are provided. The phase separator includes a first separation unit and a second separation unit, each of which has walls defining a coagulation area. One of the walls adjoins a deflector inclined to the horizontal and vertical. The separator also includes a plurality of parallel plates spaced from each other and vertically and horizontally inclined which each have a lower edge. The other wall of the separator adjoins one of the parallel plates and the deflector extends below and across the lower edges of the parallel plates. Each of the first and the second separation units is capable of separating a gas from a liquid by diverting the gas around one wall of each of the separation units and by creating a circulation of the liquid around at least one of the parallel plates such that liquid is directed into the coagulation area.

Abstract: A radio broadcasting system for a composite signal consisting of a frequency modulated (fm) analog signal and a multicarrier modulated digital signal is provided which is resistive to multipath degradation. The fm signal and the digital multicarrier modulated signal are fully coherent. The digital signal uses a plurality of carriers having a maximum amplitude at least 20 dB below the unmodulated fm signal. The multicarrier modulated signal is phase locked to a recovered analog fm pilot tone in the composite baseband spectrum of the fm signal which is at least 20 dB above the multicarrier modulated signal, which enables rapid and reliable acquisition of signal for coherent detection. In a specific embodiment the multicarrier modulated signal is a synthesized vector-modulated signal which is a quadrature phase shift keyed (QPSK) modulated set of synthesized carriers each occupying 9.5 kHz of spectrum replicated twenty-one times within a 199.5 kHz bandwidth with no more than two bits per vector.

Abstract: A radio broadcasting system is provided for transmitting and receiving through free space a composite signal consisting of a frequency modulated (fm) analog signal and a multicarrier modulated digital signal which is especially adapted to be resistive to multipath degradation. The fm signal and the digital multicarrier modulated signal are fully coherent. Further according to the invention, the digital signal comprises a plurality of carriers having a maximum amplitude at least 20 dB below the unmodulated fm signal and preferably, 30 dB below the analog signal. The multicarrier modulated signal is phase locked according to the invention to the recovered analog fm pilot tone at 19 kHz in the composite baseband spectrum of the fm signal which is at least 20 dB above the multicarrier modulated signal, which enables rapid and reliable acquisition of signal for coherent detection.

Abstract: A radio broadcasting system is provided for transmitting and receiving through free space a fully coherent multicarrier modulated digital signal which is especially adapted to be resistive to multipath degradation. The multicarrier modulated signal is a synthesized vector-modulated signal which is a quadrature phase shift keyed (QPSK) modulated set of synthesized carriers phase coherent with each other and each occupying a spectrum replicated multiple times within a bandwidth with no more than two bits per vector. An efficient channel coding consisting of large block size, high efficiency block coding, such as BCH 255, 239 code, is employed in connection with time interleaving of bits to mitigate the effects of frequency selective multipath and broadband multipath. The broadcast system is designed to be used in support of compressed digital audio programming material.
