Abstract: An improved cable crossover device for protecting electrical cables from damage. The device is modular in design and comprises modular sections coupled together by a strengthened interlocking system which allows for a variable length device. The main modular section comprises a solid body of elastomeric material comprising two opposed ramps. Each ramp comprises a bottom, generally horizontal surface and an inclined surface extending upwardly from the bottom surface at an angle. Each ramp merges with a central portion of the crossover device comprising a horizontal surface between which is located a plurality of U-shaped recesses, each recess comprising spaced vertical walls and a horizontal base wall therebetween. The electrical cables are positioned within the recesses, each recess being dimensioned so that more than one cable can be supported therein.

Abstract: Underwriters Laboratories lists lightning protection components as described in their UL 96, Third Edition Publication. The present invention improves on the basic lightning rod systems. The improvement provides a multiplicity of points extending in all directions from the top of a supporting rod which is designed to fit the conventional lightning rod mounting bases. The points are separated and configured to produce maximum ionization current commensurate and configured to carry an above average lightning strike current flow. The result is a hybrid lightning air terminal and lightning prevention system module named the Spline Ball Terminal (SBT). The SBT partially equalizes the charge differential between the protected site and the cloud thereby preventing many strokes from occurring. If a high energy stroke does enter the protected zone, then the SBT acts like a traditional UL approved lightning rod, but with much greater efficiency.

Abstract: An array of octagonal extruded plastic tubes connected by flexible webs is folded to form a tube bundle with flat surfaces of the outer octagonal periphery of each tube engaging flat surfaces of two other tubes so that four flat surfaces of the tubes define a square cross section central space for receiving cabling.

Abstract: A current pass-through arrangement for a rodlike electrode passing substantially perpendicularly through a hot wall of a container features an inner seal and an outer seal, with the outer seal located at a substantially cooler position than the hot wall. Preferably, a portion of the electrode is tightly fitted into a cylindrical bushing of electrically insulating material. The electrode projects out of this bushing, at least at the container-adjacent end. In turn, the bushing is tightly fitted into a wall element (4) having a smaller-diameter end and a larger-diameter end which is sealed into the container wall. The wall element (4) and the electrode centered within it define an annular space which is at least partly filled with sealing material (5). According to a further embodiment, the electrode also projects from the container-remote end of the bushing (3).

Abstract: Potentially harmful electromagnetic radiation associated with high voltage power transmission lines is reduced or minimized by splitting the current delivered to a load between at least three conductors, and by maintaining a specific spatial relationship between the respective conductors. Single phase transmission at reduced radiation may occur using three or four conductors spatially positioned, as viewed in a cross sectional plane, in a horizontal line or a rectangular array, respectively. Three phase transmission at reduced radiation may occur using five or six conductors spatially positioned in the corners of a rectangular array, with one conductor in the center, or a hexagonal array, respectively.

The two elements of the strain relief are braced against an inside wall of the cup-shaped housing portion. The closure portion is formed by one of the two elements of the strain relief.

Abstract: A plastic insulator for holding electrified wire comprises a support for an electrified wire and a connector device for selectively connecting the support to structures of different types. The connector device includes arms which have fastener receiving holes or apertures by means of which the support may be connected to a wooden post structure with separate fasteners. The arms also have oral apertures by means of which the support may be connected to a non-conductive rod structure without separate fasteners.

Abstract: A cable assembly 100 capable of electromagnetic interference suppression a cable strain includes relief 106, a tubular electromagnetic interference suppressor 110 located within the strain relief 106, both of which are disposed around electrical cable 102. The electromagnetic interference suppressor 110 attenuates any electromagnetic interference ("EMI") which might get coupled to electrical cable 102. By attenuating the EMI coupled to electrical cable 102 the problems associated with the electromagnetic interference can be minimized.

Abstract: An adjustable dielectric bus support clamp with a liner has a duct sidewall for adjustably supporting dielectric clamps which support high current capacity electrical conductors. A resilient dielectric liner fits between the dielectric clamp and the electrical conductor to fill high potential voids and provoide corona damping, while at the same time allowing different sized liners to be used with different sized conductors.

The escutcheon grommet has two transversely extending end-panels for abuttable attachment to two opposed upright-ends of the furniture opening and each is centrally provided with an end-ledge, has a longitudinally extending and cross-sectionally regular rear-panel of selectable length and which is abuttable at a third end of the furniture opening and which is removably attachable to the end-panels, and has a cover-plate removably restable upon the end-ledges and rear-panel and having a convex fore-end for non-chafably confronting the upwardly emergent electrical cords.

Abstract: A connector is provided for the conductors running between the electrode-containing ends of a neon tube and the high voltage power supply. Two half-shells composed of rigid insulating plastic are joined together to form a housing after the electrical connection is made between a power supply lead wire and the neon tube to completely enclose the connection. At least one end of the housing resulting from combining the half-shells contains a substantially round hole and a circular groove inwardly thereof. An insulating feedthrough adapter has an integral collar which is captured in the groove. A spirally grooved or corrugated flexible insulating sleeve screws onto the adapter which results in the lead wire being double insulated. One of the end portions of the neon tube fits through a hole in the insulating housing opposite of the hole in which the adapter resides.

Abstract: A low conductivity mounting stud for attaching an electronic component to a base structure such as a heat sink eliminates the need for several insulating washers and other insulators around the shaft of the mounting stud. The mounting stud may be composed of ceramic material such as partially stabilized zirconia. The mounting stud is secured with a press-on fastener such as a "Tinnerman nut".

Abstract: A wiring layout for new home construction in which primarily two different cables distribute various electrical signals from a central location to different rooms in a home. The first cable, an AC power and internal communications cable, is a ribbon cable containing power conductors and digital data conductors. A predetermined number of lengths of this ribbon cable form that number of branches from the central location to different areas of the home. The second cable, the external communications cable, is a cable containing coaxial conductors and twisted wire pairs in one casing. This cable is run from the central location to a splitter. A predetermined number of lengths of the second cable are then run from the splitter to selected locations in some or all the rooms. The resulting layout from this combination branch-star layout allows efficient transmission of signals through a home and enables reduced installation costs.

Abstract: Simple lightning rod systems divert a lightning stroke away from a protected facility. They do nothing to prevent a lightning stroke from occurring. The present invention represents the state of the art improvements in lightning prevention systems. These prevention systems are termed dissipating systems because they neutralize the charge differential between the cloud and the protected facility before the flashover point occurs. The flashover point is seen as lightning. The present dissipative systems leak off the charge differential slowly before the flashover point is reached. The present invention pinpoints the critical design parameters for the optimization of dissipative array systems. The critical design parameters include the number, size and spacing of both the ionizer points and their conductive wires. These Dissipation Array Systems (DAS) provide up to 100% prevention protection from lightning strokes.

Abstract: A printed conductor including two twisted conductor lines each have a plurality of segments disposed alternately on opposite surfaces of a circuit board, the successive segments of each line being connected by electrically conductive elements passing through through-holes in the circuit board. The use of such printed conductor improves the transmission characteristics of the printed circuit in the high-frequency range.

Abstract: A wire harness protector for use in an appliance. The wire harness protector consists of two members. A first member is secured to the door so as to pivot therewith. A second member is also secured to the door but remains stationary when the door is pivoted. Thus, when the door is pivoted, the second member is fixed relative to the door support structure and the first member pivots with the door. Both the first member and the second member include conduits which are aligned with the hinge axis of the door. Each of the first and second members forms an enclosure for enclosing and routing the wire harness. The conduits are formed by U-shaped channels and covers therefor. The covers are held in place by means of locking snaps. The entire first and second members may each be formed in a single integral molding process from a thermosplastic material such as a fire retardant polypropylene.

Abstract: A lightning protection installation for boats comprising a copper lightning rod mounted on the top of the mast or, in the case of a power boat, mounted on the deck, a copper wire attached to the rod and running downwardly to a point where it is attached to a retractable copper conductor. The copper conductor is retractable through a plastic or fiberglass tube or box molded or inserted in the hull or attached to a centerboard, if available. When the conductor is raised to the passive position, it is protected from the formation of marine growth; and when it is lowered, the conductor provides sufficient wettable electrical conducting grounding surface to conduct the lightning to water ground. Raising the conductor removes the slight drag caused by the grounded conductor.
