  • Publication number: 20240405546
    Abstract: A method for automatically categorizing disturbances in an electrical system includes capturing at least one energy-related waveform using at least one intelligent electronic device in the electrical system, and processing electrical measurement data from, or derived from, the at least one energy-related waveform to identify disturbances in the electrical system. In response to identifying a disturbance in the electrical system, each sample of the at least one energy-related waveform associated with the identified disturbance is analyzed and categorized into one of a plurality of disturbance categories. The disturbance categories may include, for example, (a) voltage sags due to upline electrical system disturbances, (b) voltage sags due to downline electrical system faults, (c) voltage sags due to downline transformer and/or motor magnetization, and (d) voltage sags due to other downline disturbances.

  • Patent number: 7399442
    Abstract: Disclosed herein are methods and systems for forming a plurality of multiple layer plastic articles. The methods and systems utilize shooting pot technology in combination with a combination of thermal control elements and in some instances, specialized flow bore geometries to control a thermal property and a flow parameter of selected polymeric material flowing through the system to mold the plurality of multiple layer plastic articles. Both the systems and methods are well suited for use to perform simultaneous flow injection or sequential flow injection to form the plurality of multiple layer plastic articles. The systems and methods described therein beneficially reduce the mold cavity pitch size for multiple layer molds used with systems having shooting pot technology to a mold cavity pitch size found on conventional monolayer molds to provide a plurality of multiple layer plastic articles having a cost similar to monolayer plastic articles.

  • Patent number: 7306446
    Abstract: Disclosed herein are a method and apparatus for combining two or more streams of a polymeric material to form a plastic object. The method and apparatus are capable of ending an interior layer of the plastic object at a desired length to avoid the need to clean selected surfaces of components used to form the plastic object. The method and apparatus increase the velocity of the polymeric material used to form the plastic object in certain components used to form the plastic object. The increase in the velocity of the polymeric material facilitates the ending of the interior layer of the plastic object.

  • Patent number: 6908581
    Abstract: A method of co-extruding a plurality of plastic material flowing streams into a mold cavity produces a molded product. Inner and outer streams of covering plastic materials are combined with at least one interior stream that is to serve as an interior core of a resulting molded plastic product. The combined streams are forced to flow along annular flow paths, with the annular interior stream encased within the inner and outer annular covering plastic material stream layers. The flows of the interior stream and the inner and outer streams are controlled so that: the interior stream has a flow velocity that is greater than an average velocity of the combined stream, and the interior stream does not flow along or across a zero-velocity-gradient streamline of the combined streams.

  • Publication number: 20030161977
    Abstract: A nozzle for extruding an article has at least three layers of thermoplastic materials. A housing has a longitudinal axis. At least three extrusion dies are contained in the housing and aligned with the longitudinal axis. Each die has a face with a die channel in the face. Each die channel is a closed geometric figure. Each die channel has at least one inlet for receiving a respective thermoplastic material. Each die channel provides a respective outlet for feeding a respective one of the plurality of layers of thermoplastic materials to a respective flow channel within the housing. The flow channels deliver the plurality of layers so that at least three of the layers combine within the nozzle at substantially the same coordinate measured along the longitudinal axis.
