Abstract: Water-based formulations comprising an indicating composition dispersed in water are described. The water-based indicating compositions include an organic Bi(III) compound, a sulfur source, and a carbonate salt. Formulations further including a resin and/or an acidic additive are also described.

Abstract: Chemical indicator compositions comprising a bismuth compound; elemental sulfur; and a compound with relatively high water solubility which makes the composition alkaline when exposed to water vapor at an elevated temperature; a chemical indicator comprising a substrate and the composition coated on at least a portion of a major surface of the substrate; and methods of making and using the chemical indicator are disclosed.

Abstract: An electrical jack and plug connector each reducing crosstalk between signal wires pairs connected to the jack and plug connectors. The jack connector including a plurality of signal carrying elements and a printed circuit board placed adjacent to the signal carrying elements. The printed circuit board includes conductive traces extending from the signal carrying elements. The conductive traces are spaced from each other to form capacitive coupling between the traces and the signal carrying elements. The signal carrying element may include both conductive contacts and conductive paths formed on the printed circuit board. The conductive paths are routed such that capacitive and inductive coupling occurs between signal pair whereby crosstalk is reduced. The plug connector is selectively insertable in the jack and includes a housing in which signal wires may be inserted.

Abstract: Process for the recovery of chlorine from chlorine-containing gas mixtures in a multi-stream heat exchanger wherein the chlorine-containing mixtures are separated from other gases which would solidify or liquify in the process, either before or after compression of the mixture, and is then cooled below the dew-point of chlorine in one stream of the heat exchanger; the liquid and gaseous phases thus produced are then separated and re-passed separately through the heat exchanger, the chlorine passing to recovery and the gas phase to re-cooling before being re-passed once more through the heat exchanger prior to discharge and wherein a predetermined mixture of gaseous and liquid phases is also recycled separately through the heat exchanger before re-compression and return via the heat exchanger to the phase-separation apparatus.
