    Abstract: A method of separating sulfuric acid from spent chlorine dioxide generator liquor. The method comprises simultaneously adding to the spent liquor, a water-soluble organic compound selected from the group consisting of alcohols and ketones, and water. The resulting solid is separated to leave an aqueous solution of sulfuric acid. The method is of particular application in acid and salt cake recovery from the effluent of a chlorine dioxide generator operating at an acid normality of between 6 and 11.

    Abstract: A method and apparatus of reinforcing a cable includes wrapping a flexible wire around at least a portion of an external surface of the cable, and soldering the flexible wire to the cable, thereby positioning the flexible wire with respect to the cable. The portion of the external surface of the cable wrapped with the flexible wire may be disposed between the cable and a connector, or represent an entire length of the cable. Wrapping the flexible wire may involve wrapping the flexible wire around a portion of the external surface of the cable such that coils of the flexible wire are disposed apart from each other, and sliding the coils together such that the coils of the flexible wire are touching each other.

    Abstract: A multi-polarized scanning phased array antenna is provided, which includes a first element, second element, first feed line, second feed line, first 180 degree phase shifter, second 180 degree phase shifter, third 180 degree phase shifter, fourth 180 degree phase shifter, θ1 degree phase shifter, and θ2 degree phase shifter. The first element is fed with a first polarization signal at a first feed point and a third feed point, and a second polarization signal at a second feed point and a fourth feed point. The second element is fed with the first polarization signal at a fifth feed point and a seventh feed point, and the second polarization signal at a sixth feed point and an eighth feed point. The first feed line is coupled to the elements and associated with the first polarization. The second feed line is coupled to the plurality of elements and associated with the second polarization. The first 180 degree phase shifter is coupled in the first feed line between the first and third feed points, and the second 180 degree phase shifter is coupled in the second feed line between the second and fourth feed points. The third 180 degree phase shifter is coupled in the first feed line between the fifth and seventh feed points, and the fourth 180 degree phase shifter is coupled in the second feed line between the sixth and eighth feed points. The θ1 degree phase shifter is coupled in the first feed line between the third and seventh feed points, and the θ2 degree phase shifter is coupled in the second feed line between the second and sixth feed points.
