  • Patent number: 8075847
    Abstract: The invention relates to a detergent dispenser for dosing a quantity of solid detergent by dissolving some of the solid detergent in a liquid solvent, in particular in water, to form a detergent solution, and feeding the detergent solution to a detergent outlet. The dispenser comprises a housing (1) with a chassis (2) for wallmounting or the like and a solid detergent reservoir (3). The solid detergent reservoir (3) comprises a detergent compartment (4) holding the solid detergent, a solvent application compartment (7), a liquid solvent dispensing means (9), a solvent supply conduit (10) leading to the solvent dispensing means (9), a detergent solution collector means (11), and a solution conduit (12) connected to the detergent solution collector means (11) to carry away the detergent solution towards a detergent outlet. The invention is particularly convenient, because the solid detergent reservoir (3) is constructed as a modular unit easily separable from the housing (1).

  • Patent number: 8076154
    Abstract: A use composition monitor determines the concentration of peracid and/or peroxide in a use composition using a kinetic assay procedure. A sample mixture containing a sample of the use composition, a diluent and at least one reagent is prepared and analyzed using, for example, an optical detector. Response data obtained by the detector is used to determine the concentrations of peracid and/or peroxide in the use composition based upon an evaluation function determined by a calibration method. The calibration method includes determining coefficients of the evaluation function based upon known concentrations, and measured response data of calibration samples.

  • Patent number: 8076155
    Abstract: A use composition monitor determines the concentration of peracid and/or peroxide in a use composition using a kinetic assay procedure. A sample mixture containing a sample of the use composition, a diluent and at least one reagent is prepared and analyzed using, for example, an optical detector. Response data obtained by the detector is indicative of the optical absorbance of the sample mixture as a function of time. A processor analyzes the response data to determine a corresponding best fit linear relationship. Depending upon an expected concentration range, the initial absorbance and/or the slope of the best fit equation are used to calculate the concentrations of the peracid and peroxide in the use composition.

  • Patent number: 8069719
    Abstract: Embodiments of the invention provide devices and methods for measuring fluid volume. Devices according to some embodiments include a chamber, having a pair of gears rotatably mounted therewithin. Fluid flow through the chamber causes rotation of the gears, such that each rotation and/or partial rotation results in a known volume of the fluid passing through the chamber. An optical sensor positioned outside of the chamber, can view the rotating gears through a substantially transparent chamber wall. The optical sensor can view an optical characteristic of one or both of the gears, and based upon this data, fluid volume, flow rate, and/or flow direction can be determined. Devices and methods disclosed herein can provide for improved precision in fluid flow meter measurement. In addition, the devices and methods used herein can be more durable and easier to fabricate than previously known positive displacement flow meters.

  • Publication number: 20110291033
    Abstract: A microflow analytical system includes a laminate pump assembly connectable with one or more sources of fluid, one or more pneumatic control pumps, a mixer, and a sensor. The laminate pump assembly is adapted to deliver predetermined volumes of the fluid(s) through a plurality of flow paths which are formed within layers of the assembly. Each flow path can include an inlet valve, a pump valve, and an outlet valve each of which are controllable by the pneumatic control pumps. A series of manifolds can be formed within the layers of the pump assembly to provide for simultaneous activation of selected flow paths. Delivered fluid volumes can be mixed in the mixer which, in some embodiments, may be integral with the laminate pump assembly. The sensor can measure one or more characteristics of the mixed fluids to determine one or more properties of the fluids.

  • Publication number: 20110284090
    Abstract: A solid chemical product is dispensed to prepare a requested amount of a use solution having a requested concentration of the chemical product. In some examples, a target amount of a diluent and a target amount of the chemical product required to prepare the requested use solution are determined. The target amount of the diluent is dispensed into a container. At least some of the diluent in the container is applied to the solid chemical product to create a resultant use solution, which is directed back into the container. The diluent from the container is applied to the chemical product until the amount of the use solution in the container satisfies the requested amount. In some examples, the target amount of the diluent and the target amount of the chemical product are measured by weight.
