摘要： A method of modifying a Ziegler-Natta type polyolefin catalyst comprises contacting the Ziegler-Natta catalyst with olefin monomer to form a prepolymerized catalyst. The prepolymerized catalyst can comprise a reduced number of catalyst particles having a size of 40 microns or less. The prepolymerized catalyst can be used in a polymerization process to produce polymer fluff particles with a reduced number of polymer fluff fines than the Ziegler-Natta type catalyst.

摘要： The unit for retaining/securing a fiber optic cable comprises an enclosure including a tray having a back base plate, a top and a bottom sides and a unit for retaining/securing a fiber optic cable, disposed in an interior of the enclosure. The bottom side is provided with a pair of identical apertures. Each aperture resembles to a flat shovel having an upper rectangular shape continued by a circular sector; the aperture is so profiled as to engage alternatively a biting-retaining fixture for inserting a cable or an exit grommet for a leaving cable; the former is made of a rigid plastic, while the second—of a soft, elastic polymer. The unit for retaining/securing a fiber optic cable is actuated by a shifting lever, having a shape of an angled, cantilevered part with a longitudinal axis of symmetry bent generally at 90 degrees.

摘要： In some implementations, legibility of an image may be automatically determined based, at least in part, on text contained in the image. For example, image analysis techniques may be used to identify text components in an image. One or more features of each text component may be determined for use in assessing the legibility of the text component. For example, a classifier trained on the one or more features may provide a confidence level indicative of the legibility of each text component. The confidence level for each of the text components may be compared to a legibility threshold for determining whether the text component is legible or illegible. Based, at least in part, on the determination as to how much of the text in the image is legible or illegible, an overall legibility of the image may be assessed.
