Abstract: A light fixture may include a light engine, a housing, and a mounting clip, and the light engine may include a mounting substrate, at least one light source, and at least one electronics board. The mounting clip may mount the at least one light source and the at least one electronics board on the mounting substrate, and the mounting clip may also mount the light engine on the housing. The light fixture may include an end cap that is removably attached to an end of the housing of the light fixture. In some cases, the light fixture may include a mounting system that includes at least one of a mounting bracket or an alignment bracket.

Abstract: A polymer processing system includes a mixer. The mixer includes at least one side wall and a bottom wall that cooperate to define a chamber. At least one side wall also defines a bore. The mixer also includes a pair of rotors that are disposed in the chamber and are rotatably received by the at least one side wall for mixing polymers. The mixer also includes at least one injector that at least partially extends through the bore of the at least one side wall. The polymer processing system also includes a ram that is movably connected to the mixer. The polymer processing system also includes a compressed air supply that is fluidly connected to the at least one injector to supply compressed air to the chamber through the at least one injector.

Abstract: Systems and methods are provided to monitor and control peripheral devices at a remote operational site. A management platform configures a site controller deployed at the operational site, wherein configuration specifies collection of data from the peripheral devices connected to the site controller. Conditions that monitor device status and specify device alarms triggers also can be configured. Commands, which can be part of a script, remotely control peripheral devices functionally coupled to the site controller. Collected data is conveyed through a wired or wireless link to management component, which stores the data for analysis and report generation, and can supply the data to an authorized terminal. Data and reports can be conveyed to one or more systems and mass storage functionally connected to the management component. Analysis includes data trend generation. Reports include features of observed and predicted data, and alarm summaries.

Abstract: A simple and efficient process and automated system is provided for controlling the mixing of polymeric material and additive materials in an internal mixer to provide quality products and batch to batch product uniformity. Real time mixing temperature profiles of a plurality of good quality batches of the same product are developed. The profiles are then superimposed or averaged to produce a real time temperature curve with maximum and minimum temperature tolerance limits, thus providing a range of batch temperatures that are allowable in real time during the mixing cycle. A process control system is programmed to store the range of allowable temperatures and to signal a mixer control to change at least one of the rotor speed and the ram pressure when the real time batch temperature falls outside the reference temperature range for a predetermined period of time.

Abstract: A method and apparatus are provided for adding controlled and accurate quantities of differing oils, to a polymer processing mixer without substantially contaminating one oil with another. Oils are contained in a plurality of oil supply tanks wherein each tank is fluidly connected to the mixer by an oil supply conduit. The speed of the oil pumped through the conduit is controlled by a variable speed pump motor drive unit. The quantity of oil passing through the conduit is preferably measured by a mass flowmeter and the measurement transmitted to a controller. A multi-directional valve controls the delivery of each oil into the mixer. The controller controls the delivery of oil into the mixer in response to the transmitted measurement, by varying the speed of the pump and opening and closing the valve.
