  • Corrosion control methods
    Patent number: 9290849
    Abstract: There are provided methods of suppressing corrosion of a corrodible metal surface that contacts a water stream in a water system, the method comprising: (a) introducing into the water stream a shot dose of a treatment composition comprising a corrosion inhibitor, the shot dose being introduced into the water stream over a first time period and the water stream having a first concentration of corrosion inhibitor during the first time period; (b) then reducing the amount of treatment composition that is introduced into the water stream; and (c) after the first time period, maintaining a second concentration of corrosion inhibitor in the water stream over a second time period, the second concentration being less than 25% of the concentration of corrosion inhibitor during the first time period.

  • Method and apparatus for reactive gas remediation
    Patent number: 9227156
    Abstract: Disclosed are methods, materials, apparatus and systems for removing or suppressing ambient levels of reactive gas contaminants, particularly acidic gases, using particles of zeolite, sepiolite or other suitable carrier material impregnated with at least one treatment compound selected to react with the acidic gas(es). The methods involve contacting a contaminated gas stream with the impregnated carrier materials whereby at least a portion of the reactive gases contacts the treatment compound and reacts, thereby consuming the reactive gas molecules.

  • High voltage switches having one or more floating conductor layers
    Patent number: 9196817
    Abstract: This patent document discloses high voltage switches that include one or more electrically floating conductor layers that are isolated from one another in the dielectric medium between the top and bottom switch electrodes. The presence of the one or more electrically floating conductor layers between the top and bottom switch electrodes allow the dielectric medium between the top and bottom switch electrodes to exhibit a higher breakdown voltage than the breakdown voltage when the one or more electrically floating conductor layers are not present between the top and bottom switch electrodes. This increased breakdown voltage in the presence of one or more electrically floating conductor layers in a dielectric medium enables the switch to supply a higher voltage for various high voltage circuits and electric systems.

  • Coffee press apparatus
    Patent number: 9186016
    Abstract: An apparatus comprises a vessel comprising an open top, an open bottom, and a wall. The vessel encompasses a volume of material and fluid. A bottom assembly removably engages the open bottom. A lid assembly removably engages the open top. A plunger unit comprises a top end and a bottom end. The plunger unit passes through the lid assembly to extend to at least the open bottom. A filter assembly is in engagement with the bottom end and the cylinder wall. The filter assembly substantially separates the material and fluid with a movement of the plunger unit towards the open bottom and compresses the material against the bottom assembly. The separated fluid is removable from the open top, and the compressed material is removable by a disengagement of the bottom assembly and continued movement of the filter assembly towards the open bottom.

  • Optical signal processing
    Patent number: 9069192
    Abstract: An optical regenerator for regenerating a multi-level phase encoded signal. A first non-linear medium (HNLF1) generates a comb of frequency harmonics from the signal under the action of a coherent pump, each component bearing the phase encoded data. A filter selects the first and (M?1)th order components. The filtered signal is then input to a second non-linear medium (HNLF2) where a further pump is applied, to coherently add the first and (M?1)th order components and regenerate the signal by reducing phase noise.
