Abstract: A die set can be provided for use in a crimping tool to crimp a connector onto a conductor. A first die of the die set can include a mating surface and a working surface. The mating surface can selectively mate with the crimping tool. The working surface can include an indenting member that projects away from the mating surface to form an indentation in the connector when the connector is crimped to the conductor by the crimping tool. The indenting member can include a plurality of non-planar faces, each of the plurality of non-planar faces including a concave portion.

Abstract: A crimping tool uses a die set with a single point indenter profile to allow of a wide range of electrical connectors and conductors without changing die sets and/or crimping tools. This avoids the need to purchase a separate crimping tool. A die set with an indenter feature in two configurations encompasses the required range of conductors in existing crimping tools, consisting of two pyramid indenter dies and one common wedge die. One advantage of this invention is it allows the strength and versatility of a die set with a single-point indenter without the purchase of a separate crimping tool. The dies of this invention do not require switching out for different sized lugs, thus reducing misplacement and loss. The die halves replace numerous standard U-dies, making the dies of this invention more appealing while offer enhanced pullout strength of connections resulting from this invention.

Abstract: A polymer filtration apparatus for sealing a slide plate translatable across a bore of an extrusion or mold machine, includes an annular seal having a sealing surface which is biased against the slide plate by a spring mechanism. The annular seal has a thrust surface which is angled relative to the sealing surface and the thrust surface is located at an opposite axial end of the annular seal from the sealing surface. The spring mechanism can be a single spring with overlapping tangs or a multiple spring assembly in overlapping relationship, with or without tangs, to form a continuous barrier. The spring assembly is used to exert a radial force against the thrust surface of the annular seal to bias the seal in an axial direction against the downstream slide plate. In operation, pressurized polymer melt in the extrusion bore further biases the spring against the annular seal which is then transferred to the seal and the slide plate.

Abstract: A fiber optic cable including a cable core having at least one optical fiber and a ripcord. In one embodiment, the ripcord is a conductive material operative, upon application of a sufficient pulling force, to rip at least one cable component for facilitating access to said at least one optical fiber. In other embodiments, the ripcord is formed from a semi-conductive material, the ripcord is removably attached to at least one cable component, and/or the ripcord has an excess length.

Abstract: A fiber optic cable including at least one tube assembly therein. The tube assembly includes an optical fiber ribbon stack in a tube. The optical fiber ribbon stack comprises optical fiber ribbons arranged at least partially in a gradually decreasing optical fiber count profile. A diagonal free space of the tube assembly being about 0.5 mm to about 5 mm. The diagonal free space is defined as the tube inner diameter minus the maximum diagonal length of the ribbon stack. The maximum diagonal length of the ribbon stack being the greater of either a diagonal measurement across lateral subgroups of the ribbon stack or a diagonal measurement across a major dimension of a medial subgroup of the ribbon stack.

Abstract: A box for covering components or the like and for preventing unwanted access thereto. The box comprises a mounting panel having a pair of opposed sides, a top portion, a bottom portion and a back portion. The back portion is adapted to receive a fastener for mounting the mounting panel to a mounting surface. A cover fastener is received within the mounting panel. A slot is formed in the mounting panel and a corresponding tang is located within the cover which is adapted to receive an alarm device therein and removably envelop the mounting panel. A second opening is located in the cover for receiving the cover fastener when said mounting panel is enveloped within the cover.
