  • Patent number: 7913417
    Abstract: A system and method of controlling energy that is input to a material substance, for the controlled removal of moisture from the material substance, is disclosed. A controlled air flow is blown onto the material substance at a specified air flow rate over at least one specified time period such that the material substance absorbs thermal energy from the controlled air flow via at least one outer surface of the material substance. The controlled air flow is of a specified humidity level at a specified temperature level. The material substance is also irradiated with microwave energy at a first specified power level for at least a first specified time duration such that the material substance absorbs at least a part of the microwave energy and converts the absorbed microwave energy to thermal energy within the material substance. As a result, moisture is removed from the material substance in a controlled manner.

  • Patent number: 7339674
    Abstract: A color adjustment system for changing the color of fluid flowing from a source. The color adjustment system includes a main mixing pipe connected to storage vessels to continuously receive flows of colorants from the storage vessels. A fluid inspection cell is connected to the main mixing pipe for continuously receiving a sample portion of the flow of the fluid composition. A spectrophotometer is positioned to view the sample portion of the flow of the fluid composition through a window of the fluid inspection cell. The spectrophotometer transmits measured color values to a control unit, which generates control signals in response thereto. The control signals are transmitted to colorant pumps, which pump colorants to the main mixing pipe in response to the control signals.

  • Patent number: 7129278
    Abstract: The overall performance of water-reducible polymer dispersions, more specifically alkyd dispersions, can be substantially improved by utilizing resins derived from acidolysis reaction products of polyalkylene terephthalates and polyalkylene naphthalates. According to this invention, polymer dispersions can be produced from low acid value polymers and yet have good water dispersibility. When an aqueous coating composition is formulated using the dispersion of this invention, a final coating is formed that has good hydrolytic stability, and when blended with a latex, exhibits improved gloss and wet adhesion.

  • Patent number: 7116420
    Abstract: A method of producing a finish for a selected wood substrate, wherein the finish provides the selected wood substrate with a color that matches the color of a target object. In accordance with the method, calculations are performed to determine the quantities of at least one group of colorants required to produce a semitransparent wood stain from a vehicle, wherein when the semitransparent wood stain is applied to the selected wood substrate, the selected wood substrate will have a color that matches the target object. The calculations are performed using reflectance measurements of the target object obtained using a spectrophotometer and previously obtained spectral data of the colorants as applied to at least one type of wood. The colorants used to form the semitransparent wood stain do not include a white colorant.

  • Patent number: 7042566
    Abstract: A method of verifying the color and tinting strength of a manufactured batch of a semi-transparent wood stain. In accordance with the method, a standard batch of the wood stain is formed and then mixed with a specified amount of a white colorant to form a standard measurement batch. A test sample of the manufactured batch is obtained and is also mixed with a specified amount of the white colorant to form a test measurement sample. Layers of the standard measurement batch and the test measurement sample are formed on the substrates and complete hide obtained. Reflectance measurements of the layers are made using a spectrophotometer. The reflectance measurements are used to determine if the color and the tinting strength of the manufactured batch is within an acceptable deviation range of the color and tinting strength of the standard batch.
