    摘要： A system is provided for dispensing fluids comprising a housing and a flexible refill pouch (1), whereby the housing comprises a reservoir (2) into which the pouch can be positioned, and which contains a piercing member (5) tightly connected to the bottom part thereof and projecting therefrom outwardly into said reservoir, and further a platform (3) for positioning the pouch which platform is movably attached around the piercing member to the bottom part of the reservoir such that it will move down into the direction of said bottom part when a full pouch is placed onto it and will return to its original position when the pouch becomes empty. This system can be effectively operated with a blunt piercing member (6).

    摘要： Tableted detergents are formed from a hydrated phosphate sequestrant, caustic, free water and, optionally, fillers by combining the products and tableting the components without permitting the tablets or detergent to exceed 50 °C. In a preferred embodiment where fillers are incorporated, all free water is combined with the phosphate sequestrants, both anhydrous and hydrated. After the water has been absorbed by the sequestrants, the filler and caustic can be added and the detergent tableted. The free water is bound sufficiently tightly to the phosphate sequestrant that it does not rapidly react with the anhydrous caustic, maintaining the temperature at less than 50 °C, which in turn prevents the water of hydration in the phosphates from reacting and thereby weakening the formed tablets. The tablets can also be formed by combining the filler with the phosphate sequestrants and water and subsequently adding caustic if the detergent is cooled and its temperature maintained below 50 °C until the hydration reaction with the caustic and free water is complete.

    摘要： A method is provided of dosing detergent product into a washing solution present in an industrial washing machine, comprising measuring, from a washing solution containing water and detergent material, a property which is proportional to the detergent concentration of said washing solution, and adding detergent product to the washing solution if the value of the measured property corresponds to a detergent concentration below a preset threshold value, whereby the measured property is the electroconductivity of the washing solution, said property being measured using a measuring cell including one or more electrodes (3, 4) characterised by the steps of: (a) dosing, during filling of the washing machine with clean water, a sufficient amount of detergent product so as to attain present threshold value, followed by mixing of said dosed tetergent product with the water; (b) measuring the conductivity of the thus obtained wash liquor, after a mixing time of less than 2 minutes; and (c) storing said measured conductivity and the detergent concentration value corresponding thereto, as the preset threshold values, in the memory (3) of a controller (1), which is attached to the measuring cell and controls the dosing of detergent product as a function of the conductivity measured.

    摘要： A sensing arrangement for sensing the addition of reactants to a solution (12) within a tank (14) which includes a first inlet (16), a second inlet (18), and a reactant supply controller (28) for controlling the addition of reactant into the tank through the first and second inlets. The first inlet is configured to supply a first reactant (20) to the tank and the second inlet is configured to supply a second reactant (24) to the tank. The sensing arrangement comprises a detector (34), such as a conductivity detector or an ion concentration detector, having a probe (36) for measuring the presence of the reactants in the solution within the tank. The probe (36) is positioned substantially adjacent to the second inlet (18). The detector provides a mechanism for measuring the presence of and concentration of the first reactant in the solution while the first reactant is added to and mixed with the solution. The detector (34) also provides a mechanism for measuring the presence of the second reactant (24) in a portion of the solution (12) substantially adjacent the second inlet (18) as the second reactant is being added to the solution thereby detecting the influx of the second reactant as it is introduced into the tank (14).
