  • Patent number: 8540937
    Abstract: A system and/or method formulates a chemical solution using both volumetric and weight based measurements of components of the chemical solution. The components of the chemical solution include water and at least one other component, which may take any form, such as, without limitation, liquid, solid, powder or gaseous form. Formulation of the chemical solution is administered by combining water with the one or more other components at an output port, from which this combination is dispensed to a solution storage tank. In response to a user's request to formulate a specified amount of the chemical solution, the volume of water provided to the output port is monitored by a flow meter and the weight of the other component(s) provided to the output port is monitored by one or more load cells. Based on such monitoring, appropriate amounts of water and the other component(s) are combined together to formulate the specified amount of the chemical solution in the solution storage tank.

  • Publication number: 20110174340
    Abstract: An enzymatic system includes a first pH neutral composition and a second pH neutral composition. The first pH neutral composition includes a low temperature enzyme effective at removing blood and hemoglobin. The second pH neutral composition includes a high temperature enzyme effective at removing mucous, fibrin and fat. In one embodiment, the low temperature enzyme has an activation temperature of about 50 degrees to about 120 degrees Fahrenheit and the high temperature enzyme has an activation temperature of about 140 to about 180 degrees Fahrenheit.
