Abstract: A composite insulator containing means for providing early warning of impending failure due to stress corrosion cracking, flashunder, or destruction of the rod by discharge activity conditions is described. A composite insulator comprising a fiberglass rod surrounded by a polymer housing and connected with metal end fittings on either end of the rod is doped with a dye-based chemical dopant. The dopant is located around the vicinity of the outer surface of the fiberglass rod. The dopant is formulated to possess migration and diffusion characteristics, and to be inert in dry conditions and compatible with the insulator components. The dopant is positioned within the insulator such that upon the penetration of moisture through the housing to the rod through a permeation pathway in the outer surface of the insulator, the dopant will become activated and will leach out of the same permeation pathway or diffuse through the housing.

Abstract: A cord end cover includes a female member having a hollow shape with two open ends, and a male member having a leg part to be inserted into the female member from one open end of the female member, and a head part to be fitted into the one open end of the female member for covering the one open end at a final position of the insertion. A spike-like projection is formed on a side of the leg part of the male member along a direction of the insertion. When the leg part is inserted into the female member in a state in which the spike-like projection bites an end of a cord inserted into the female member from the other open end of the female member and drawn out from the one open end, the end of the cord is held between the spike-like projection and an inner surface of the female member.

Abstract: An insulator bushing wildlife guard having features for easier alignment and installation of the guard on the bushing. The guard has two hinged body sections of insulating material. An outer edge of each body section is provided with a plurality of flexible fingers that allow conductors to pass through from the interior to the exterior of the enclosure when the two portions of the guard are engaged. In one embodiment, the guard is spring biased toward a closed position. A handle on the back has inner grooves to make it easier to grasp and manipulate the guard using a shotgun stick. On a lower front side of each portion of the guard, spaced-apart, curved, horizontal upper and lower flanges help align the guard with the topmost skirt of a bushing. Medial walls having a curved, sloped, concave or otherwise inwardly-directed configuration between the two flanges facilitate forcing the guard open by pushing it against the bushing.

In one embodiment, the receptacle has a cam that is selectively engageable with the frame for clamping the circuit cards within the frame. In another embodiment, a shaft is rotatably attached to the receptacle. The shaft has a head at one end and a nut opposite the head. A resilient element is disposed on the shaft between the head and the nut. The resilient element is axially compressible between the head and nut to bulge generally perpendicularly to the axial direction into engagement with the frame for clamping the circuit cards within the frame.

The feedthrough assembly comprises a plate and at least one electrical contact which extends through the plate. Preferably, a heating member is further provided to extend along a circumference of the plate. The plate is sized to span and surround the aperture so that, upon generation of heat by the heating member, at least one ring of sealing material adjacent the heating member flows to establish a seal between the plate and the housing wall surrounding the aperture. The heat is preferably generated by applying current to the heating member. The feedthrough assembly is preferably fabricated using a microfabrication process. A batch fabrication operation is preferably employed so that a population of the plates are formed from a single panel and subsequently separated therefrom.

Abstract: An elbow terminator has a socket in which an electrical probe is disposed. The terminator is insertable onto an electrical bushing such that a tongue of the bushing is received in the socket of the terminator, and the probe of the terminator is electrically coupled to a contact sleeve disposed within the tongue. A latching mechanism produces positive latching between the tongue and socket when the tongue has been inserted to a predescribed depth within the socket. In order to enable an operator to visually observe that the tongue has been inserted to the prescribed depth, the bushing carries a color band which becomes completely disposed (invisible) in the socket when positive latching occurs. Alternatively, the bushing can be provided with gauge tabs which become aligned with a witness line formed on the terminator when positive latching occurs.

A second opening is formed in the second member. The first and second openings are adapted to receive a sealant. A first fastener is inserted through the first and third fastener holes and a second fastener is inserted through the fourth and second fastener holes to secure the first member to the second member on the insulator assembly.

In position, the anchoring member resides against a surface of a structural frame member to hold the first end portion outside of the target internal routing space and allow the second end portion to extend into the target internal routing space, thereby allowing one end of the rod to remain in a fixed location without requiring a second installer. The elongate rod can be a glow rod.

Abstract: An optical filter device (100) for collimating input signals and selecting optical signals in a predetermined wavelength band includes a dual fiber pigtail (DEP) (112) receiving an input and output optical fibers (113, 114), a molded lens (111), a sleeve (130), and a filter (120). The molded lens between the DFP and the filter has a single index. The molded lens collimates dispersed-light beams coming from the input optical fiber to parallel-light beams, and converges the parallel-light beams reflected by the filter for transmission into the output optical fiber. The filter absorbs optical light beams in predetermined wavelength bands. The sleeve allows connection of the filter to the lens without requiring use of epoxy on optically functional parts of the molded lens.

Abstract: A light-emitting device includes 16 vertical-cavity surface-emitting laser diodes (VCSELs) disposed like a 4×4 grid, for example, in a sufficiently narrower range than the end surface of an optical fiber. The 16 VCSELs disposed in the light-emitting device emit optical signals in the same direction. Since the VCSELs are disposed with a concentration in the sufficiently narrower range than the end surface of the optical fiber as described above, if the optical signals emitted from the VCSELs are spread, almost all optical signals generated by the light-emitting device are incident on the end surface of the optical fiber and are transmitted through the optical fiber.

Abstract: An electrical wire bundle W is accommodated in a main body 20 of a protector 10, a cover portion 30 is closed, and the main body 20 and the cover portion 30 are locked by lock portions 40 capable of engaging the two members. Namely, if a belt-shaped retaining piece 31 extending from the cover portion 30 toward the main body 20 is inserted into a retaining hole 25 of a through hole 23 provided through an attaching portion 21 of the main body 20, a pawl portion 32 of the retaining piece 31 rides over a flexible piece 24, which is provided between the retaining hole 25 and a flexible hole 26, while deflecting the flexible piece 24, so as to be retained by the flexible piece 24. Since a widthwise dimension of the flexible hole 26 is less than a maximum widthwise dimension of the retaining piece 31, when the retaining piece 31 is inserted in the retaining hole 25, even if an attempt is erroneously made to insert the retaining piece 31 into the flexible hole26 the retaining piece 31 cannot be inserted.
