Abstract: An optical sensor may be used to measure the concentration of calcium in a water sample, such as a water sample obtained from industrial process water system like a cooling tower system, a boiler water system, or a waste water system. To measure the concentration of calcium, an indicator or reagent may be added to the water sample to form a complex that absorbs light. The absorbance profile of the complex may be non-linear over a range of calcium concentrations. However, the absorbance profile can be linearized to provide calibration coefficients that are subsequently used to determine the concentration of calcium in samples having unknown calcium concentrations. The linearization of the absorbance profile can allow the optical sensor to be calibrated using two solutions. This can reduce the complexity and cost of calibrating the optical sensor, which may otherwise require at least three calibration solutions to capture the non-linear profile of the absorbance curve.
Abstract: This disclosure relates to transfer plate lubricant compositions and methods of transporting open containers across stationary transfer plates.
Abstract: A wipe dispenser for use in metering out consistent doses of a composition onto a disposable wipe includes a mixing and dispensing assembly. The assembly has a vessel holding a first liquid for the composition and a first pump to convey the first liquid. A bottle having a second pump to convey a second liquid of the composition is stored within the bottle. A funnel arrangement is in downstream communication with the first pump and second pump. The funnel arrangement includes a mixing chamber for mixing the first and second liquids and a dispensing funnel in communication with and downstream of the mixing chamber. A wipe can be pulled through the dispensing funnel and wetted with a mixture of the first liquid and second liquid from the mixing chamber. A push bar attached to the funnel arrangement can selectively apply the force to actuate the first pump and second pump.

Abstract: A composition, method and kit for quantifying the concentration of one peracid or the total concentration of two or more peracids in a water source are disclosed. In particular, an oxidation sensitive or peroxycarboxylic acid selective leuco dye is used to react only with one or more peroxycarboxylic acids in a water source but not with peroxide usually co-existing in the water source. Not only does the oxidation sensitive or peroxycarboxylic acid selective leuco dye react with peracid(s) but also the reaction generates a color species that can be used visually or through absorbance measurement to quantify the peracid concentration. The method disclosed here is not a titration method, it involves a simple mixing step. The kit or composition disclosed here does not utilize a catalyst, such as iodine.

Abstract: A wearable computing device may be used to track the efficacy of one or more cleaning actions performed. The device can include one or more sensors that detect and measure motion associated with a cleaning event. In different examples, the movement data generated by the device can be compared to reference movement data to determine if the individual has cleaned all the objects they were expected to clean and/or if the individual has cleaned a given object sufficiently well. As another example, the movement data generated by the device can be analyzed to distinguish cleaning and non-cleaning movement actions as well as to distinguish different types of cleaning actions during cleaning movement. The quality of each cleaning action can be evaluated. In any configuration, the device may perform an operation in response to determining that ineffective cleaning is being performed, causing corrected cleaning action to be performed.
