Abstract: Systems and methods are provided for controlling a color masterbatch feed rate in production of a manufactured part to match a color of the manufactured part to a target color by adjusting a concentration of masterbatch that is mixed with a raw material and fed into a processing machine for producing the manufactured part. Control of the color masterbatch feed rate is based on optical spectral properties of an in-line manufactured part, a known reference part having the target color, and an algorithm for calculating and adjusting the color masterbatch feed rate.

Abstract: A self-cleaning dosing apparatus includes a material hopper for containing pellets of material, a feed screw, a first material outlet through which pellets of material fall by gravity onto a first end of the feed screw for the feeding of pellets to a process machine. A second material outlet is located beneath the first end of the feed screw, with a slide gate blocking the second material outlet. A pneumatic piston is provided for pulling the slide gate to unblock the second material outlet, and a Venturi pump is located under the second material outlet for pulling pellets through the second material outlet when the slide gate is opened.

Abstract: Disclosed is a system for optimizing a match between the color of an in-line part manufactured by a plastic product production machine and the color of a reference part by adjusting the concentration of masterbatch in the mixture of raw material fed to the plastic product production machine. The optimization of the color is based on interlaced spectra of the in-line part and reference part obtained using the same spectrometer, thereby eliminating the requirement for high accuracy spectrometer calibration and allowing a controller of the system to determine the rates at which the base masterbatches are added to the raw material in real time on the manufacturing floor while the plastic product production machine is being operated to manufacture in-line parts.

Abstract: A weighing apparatus for the preparation of a mixture of granular components that comprise batches of material required by a plurality of processing machines in a plant for the manufacture of plastic products is described. The apparatus comprises a Multi-Channel Gravimetric Batch Blender (MCGBB) configured to weigh predetermined weights of the raw materials and to combine the weighed portions of raw materials into batches according to a predetermined recipe for each processing machine and a computer that controls the operation of all components of the MCGBB. The MCGBB comprises several weighing units arranged in a way that allows material weighed in each of the weighing units to fall through individual chutes via a common funnel into a manifold that distributes the weighed batches to several processing machines via a system of delivery pipes.

Abstract: The invention is a weighing and feeding system for accurate weighing of small quantities of material in pelletized form and feeding the weighed material to processing machines. In particular the invention, is suitable for the preparation of weighed quantities of masterbatch to be added with resin directly into injection molding or extrusion machines for the manufacture of plastic products.

Abstract: A vehicular adapter (100) provides an interface to accommodate a variety of contacts located on different surfaces of a portable radio (200). The vehicular adapter includes a rotating pocket (116), pivot arms (136, 150, 152) and a locking mechanism (126). The rotating pocket (116) provides a first set of contacts (124). One pivot arm (136) provides an antenna probe (120) on one surface of the vehicular adapter while another pivot arm (152) provides connector side contacts (122) to a side surface of the vehicular adapter. The pivot arms (136, 150, 152) pivot in response to the rotating pocket (116) being rotated thereby moving their respective contacts into position for mating with the portable radio (200).
