Abstract:
A portable color measuring device is provided that includes a hand-holdable housing. The color measuring device is configured to receive an independently operable processing device that is mounted to the housing. The independently operable processing device is a portable general purpose computer that executes software applications to control the operation of the color measuring device and process color data. The color measuring device measures the color properties of a sample by illuminating the sample with a light source. The measured properties are processed and/or analyzed by the independently operable processing device and results are displayed to a user. Software applications reside on the independently operable processing device allowing software upgrades or modifications to be easily performed. New applications can be downloaded to the processing device or the processing device can be interchanged with a different processing device.
Abstract:
A method and apparatus for providing an integrating sphere for use as a measuring device is described. More specifically, the integrating sphere includes a generally spherical shell and a liner disposed within said generally spherical shell, wherein the liner is composed of a sintered polymer. In one embodiment, the liner is made up of a pre-formed polytetrafluoroethylene (PTFE) shell.
Abstract:
A dyeing machine (10) comprises multiple dye beakers (12), a rotating support assembly (14) mounting the beakers (12), a frame (30) mounting the support assembly (14) for moving the beakers (12) about an axis of rotation (32), and a dye coupling (64) on the frame (30) for receipt of dye and other chemicals from a dye source. At least one beaker (12) is provided with a dosing hose (47) mounted on the rotating support assembly (14) for supplying the beaker (12) with a dye and other chemicals during movement of the rotating support assembly (14). In addition, a receiving end of the dosing hose (47) is in fluid communication with the dye coupling (64).
Abstract:
A system for calibrating a spectrophotometer includes a spectrophotometer (10) including a network communication interface (12), operating in a plurality of modes and producing and implementing diagnostic information. A network communicates with the spectrophotometer (10) via the network communication interface (12). A remote processor (22) is enabled to communicate with the spectrophotometer (10) directly via the network communication interface (12). Alternatively, a spectrophotometer having a thin client is disclosed that can operate independently of a local PC.
Abstract:
A dyeing machine (10) includes a beaker (12) and a carrier (36) within the beaker (12). The carrier (36) includes perforations (42) and supports a sample (50). A pump assembly including a fluid pump (20), impeller (22), drive shaft (24), magnetic flange (14) and flow guide leement (26), circulates a processing solution (30) to a first side (44) of the carrier (36). The processing solution (30) passes through the perforations (42) for dyeing the sample from the inside-out.

Abstract:
A method for improved, automated, repeatable color matching on materials with different properties is provided. The method includes color matching on different materials using acquired, manipulated, and synthetic reflectance curve data. In one example, resulting synthesized reflectance data is employed in formulating a matching colorant.
Abstract:
A method for improved, automated, repeatable color matching on materials with different properties is provided. The method includes color matching on different materials using acquired, manipulated, and synthetic reflectance curve data. In one example, resulting synthesized reflectance data is employed in formulating a matching colorant. An example method uses a spectrophotometer to collect reflectance curve data from a physical sample colored to a desired color. The reflectance curve data is employed to produce computer display outputs of substrates as they would be appear if colored with the desired color. The method includes using a colorimeter to collect colorimetric data from the outputs on the display. The sets of colorimetric data are compared and data that facilitate manipulating the reflectance curve data associated with the desired color is produced. The synthetic reflectance curve data facilitates producing matches for the various substrates as colored and displayed on the computer display. The synthetic reflectance curve data may also be used to manipulate colorant formulae. It is emphasized that this abstract is provided to comply with the rules repuiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the application. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
