Abstract: A flexible timebase for eye diagrams uses a stable free running oscillator as a sample clock for equivalent time sampling of an input serial digital signal and of a reference signal, such as a sine wave, derived from a subdivided recovered clock of the input serial digital signal. The reference signal samples are provided to a digital phase-locked loop that provides the flexible timebase to an eye pattern generator. The eye pattern generator accumulates the input serial digital signal samples at times corresponding to the reference signal samples to produce the eye diagram. A linear phase detector in the digital phase locked loop converts the reference signal samples to a complex signal using a Hilbert transform and then to a linear ramp of phase values using a CORDIC algorithm with arctangent lookup table. A subtractor is then used to subtract the digital phase-locked loop feedback from the linear ramp to provide the input to the loop filter.

Abstract: A device for destroying microbes in a fluid medium utilizing a housing. The housing possesses an exterior and a fluid passageway formed by an inner wall portion. The housing also includes a plurality of chambers positioned radially outwardly from the fluid passageway. The chambers and enclose magnets which surround the passageway. First and second electrodes extend along the fluid passageway and lie flush with the inner wall portion. The electrodes include terminals that are available on the exterior of the housing to receive power from a source.

Abstract: An apparatus for treating water contaminated with metal sulfates and sulfuric acid such as acid mine drainage (AMD) which in part recycles high pH effluent from later steps in the process back to the earlier steps of the process. The recycled high pH effluent added with magnesium hydroxide to the entering AMD generates precipitates separable from the stream to leave sulfate ladened water. A tangential filtering process is used to separate the sulfate ladened water into one stream of pure water and a second stream containing sulfate. One portion of the second stream is treated with ammonia to yield a cake of ammonia sulfate and aqueous ammonia. Ca(OH)2 is added to another portion of the second stream to produce calcium sulfate cake and the high pH effluent that is recycled back to the first step in the cycle.

Abstract: A method and application of a disinfecting solution which comprises adding to an acid the chemical equivalent of a metal chloride plus a metal compound wherein the metal compound is one of a hydride, oxide or hydroxide and the metal is selected to form a precipitate with said acid. The precipitate is filtered from the solution leaving a deanionated chlorided hydronium complex that is non corrosive to human tissue yet has powerful disinfecting properties. Calcium is the preferred metal.

Abstract: An apparatus and method for removing contaminating metal ions and sulfate ions from acidic aqueous solution such as waste mine water which features passing the solution between pairs of electrodes, each pair of electrodes impressed with a voltage selected according to specific ion species and then adding chemical agents to raise the pH and form precipitates of the metal and sulfate ions. A magnetic field is applied during at least the first mixing step. The precipitate is then separated from the water with settling and filtering steps. The clarified solution is treated by reverse osmosis to concentrate the ammonium.

Abstract: An apparatus and method for removing hydrocarbon contaminants and heavy metal ion contaminants from wastewater stream comprising the introduction of iron ions into the stream. In one embodiment, the ions are introduced by applying an electrical current through a bed of iron particulates in the form of steel wool and iron nodules. In another embodiment, the iron salts are added to the waste stream and the iron ions are reduced to a more reactive lower valence state by electric current.

Abstract: A multi-level hierarchical bus architecture implemented with a multi-chip package and a modular shared-bus provides high bandwidth. All IC components are mounted on standardized multi-chip packages. Each multi-chip package includes bus interface chips for providing communication from the integrated circuits to a board bus. One multi-chip package contains additional bus interface circuitry for providing communication from the board bus to a backplane bus.

Abstract: A solution for cleaning metal surfaces particularly non ferrous alloys such as copper, brass and high strength aluminum alloys. The solution is prepared by mixing Ca(OH).sub.2 and KOH with equivalent sulfuric acid in water then passing the solution through a 10 micron filter. the resulting concentrate can be used full strength or diluted depending on the degree of surface oxidation of the metal to be treated.

Abstract: An apparatus for destroying bacterial pathogens including at least one pair of electrodes secured in a housing configured to constrain flow of water through the region between the electrodes. In one construction, the electrodes are supported in a tube with sides of each member of an electrode pair conforming to the inner surface of the tube and electrode surfaces form a slotted space through which the water passes. In another constrcuction, one electrode is a tube and the other electrode is a rod supported concentrically inside the tube. The treated fluid passes axially through the space between the electrodes. A conductivity meter and flow meter applies a conductivity signal and a flow rate signal to maintain the field in a value that is not too excessive so as to prevent undesired reactions.

Abstract: An apparatus for destroying bacterial pathogens including at least one pair of electrodes secured in a housing configured to constrain flow of water through the region between the electrodes. In one construction, the electrodes are supported in a tube with sides of each member of an electrode pair conforming to the inner surface of the tube and electrode surfaces form a slotted space through which the water passes. The electrodes and space between the electrodes are also subject to a magnetic field which reduces rate of deposition of calacerous deposits on the electrode surfaces thereby extending the period of time between required cleaning of the electrodes. The electrodes can be simple slabs or screens or both. The electrodes are preferably tin, titanium, brass, iron or stainless steel.
