  • Publication number: 20190292608
    Abstract: Methods to quantify bioburden present in industrial substances are provided that utilize a polymerase chain reaction (PCR) and detection of amplification signals over multiple PCR thermal cycles. The PCR targets a segment of DNA found in one or more biofouling agents that are often found in industrial substances. A sample taken from the substance can be used directly or first filtered, purified, lysed, diluted, or subjected to a combination of such pretreatments. The substance is used in, or is tested for preparedness to be used in, industrial applications and sites, such as non-pharmaceutical applications, non-medical applications, papermaking facilities, leather-treating facilities, and the like. Methods are provided to control or treat substances or systems utilizing such substances, or to control or treat surfaces intended to come into contact with the substances.

  • Patent number: 10329715
    Abstract: A method is provided for decision support in regulating an adhesive coating applied to Yankee dryers. Online sensors are configured to continuously measure stock characteristics, and additional sensors provide actual stock flow rate and machine speed. A controller predicts potential natural coating application from a fibrous sheet generated from the stock to the Yankee dryer surface, substantially in real time, based on the measured characteristics and sensed actual machine values. An output signal may be provided to a display unit, wherein an optimal adhesive coating feed rate may be determined and displayed for operator decision support. The controller may in an automatic mode be configured to regulate the adhesive coating feed rate based on a comparison of one or more determined optimal values associated with respective actual values. The method may include identifying fiber source changes in real time, and predicting a natural coating potential based partly on predetermined correlations.

  • Patent number: 10254246
    Abstract: A method is provided for measuring an electrolytically-active species concentration in an aqueous or non-aqueous solution for use in providing control of the concentration of the species in a source solution thereof based on the measurements. In the method, a sample containing an electrolytically-active species is added into a measurement cell that has a working electrode and an auxiliary electrode, and a constant current is applied to the measurement cell while the working and auxiliary electrodes are in contact with the sample with monitoring of voltage difference across the electrodes until a change in the voltage difference is detected. A feedback signal is generated based on a parameter of the change in the voltage difference that is directly proportional to the amount of the electrolytically-active species in the sample, which can be used for process control. An apparatus is also described.
