| 20100200289 | CABLE RUN - The present invention relates to a ceiling-mounted apparatus for running a cable harness, in more precise terms a ceiling-mounted apparatus for running a cable harness with a chain of guide carriages coupled to one another by means of spring elements, said guide carriages running in at least one guide rail in each instance, with a first guide carriage being connected to a cable harness source by means of at least one spring element and with the guide carriages comprising additional spring elements for attaching the cable harness. | 08-12-2010 |
| 20110315441 | Break-Away Hook Assembly - A break-away hook assembly is adapted for installation for use with a low-voltage residential communication cable. A pair of members is coupled. One of the members has a connector with a terminal portion which receives a terminus of the other member. The connector breaks to release the second member from coupled engagement with the first member so that upon application of a stress in excess of a pre-established load, the cable will sag while maintaining the communication integrity of the cable. | 12-29-2011 |
| 20120018212 | POWER CORD INTEGRATED HANGER SYSTEM FOR SUSPENDING A LIGHTING FIXTURE - A power cord integrated hanger system for suspending a lighting fixture has a flexible load bearing inner suspension part and a flexible non-load bearing outer conductor part that acts as the “power cord” for the suspended lighting fixture. The flexible outer conductor part has an internal passageway for the inner suspension part. An outer cover of the outer conductor part holds electrical conductors in place in the outer conductor part and preferably conceals the conductors from view. The outer cover of the conductor part can be provided with different aesthetic qualities to enhance the visual appearance of the hanger system. | 01-26-2012 |
| 20120279777 | VAPOR BARRIER CEILING SEAL APPARATUS - An opening in a vapor barrier membrane interior to a ceiling can be sealed by a flexible enclosure. A planar member of the enclosure can be bonded to the inner side of the membrane. The enclosure is formed with a cavity that can encompass a ceiling mounted electrical device. A fastener is joined to the planar member permits bonding thereof with an interior surface of the membrane by manual application of a compressive force. The fastener may comprise a removable release liner covering an adhesive. | 11-08-2012 |
| 20090014208 | HINGED BUSHING SUSPENSION CLAMP AND METHOD FOR USING SAID CLAMP - A clamp with a first clamp halve with a hinge portion and a first opening for a fastener; a second clamp halve, with a hinge portion and a first opening for a fastener; a cable opening; and a hinge device for connecting the two hinge portions. The clamp may also include a first clamp halve with a second opening for a closing insert. | 01-15-2009 |
| 20080230265 | Electric power cable fixing apparatus for an insulator - The present invention relates to an apparatus fixing power cable to insulator, which clamps the head of an insulator to fix power cable to the insulator head, easily and firmly. To this end, the apparatus in accordance with the present invention comprises; a main body formed with a vertical through bolt hole in the center, with a space, formed beneath the bolt hole, with round open bottom which holds power cable; a fixed clamp formed on one side of the main body with a latch at the bottom to hook insulator head; a movable clamp formed on the opposite side of the main body with a latch at the bottom to hook the other side of the insulator head; a movable, elastic holding member formed on the space part of the main body, with a groove on the bottom to hold upper part of power cable; a fixing bolt engaged in the bolt hole of the main body, pressing the elastic holding member by screwing inward, so that the power cable can be fixed between the holding groove on top of the insulator and the holding groove on the bottom of the elastic holding member; and a movable clamp fixing member to fix the movable clamp engaged with the insulator head. | 09-25-2008 |
| 20090095522 | Robotic Bypass System and Method - A system and method, and robotic equipment for mechanical and/or electrical bypassing of short sections of energized high voltage line conductors by gripping the conductor at two close-by points, making good electrical and mechanical connection, then drawing the two points towards one another so as to relieve both mechanical and current-carrying duty of the bypassed conductor section. Doing so can provide slack on the bypassed conductor section for maintenance or repair while simultaneously providing an alternative path for electric current, or increase tension on the adjacent conductor sections by essentially shortening the conductor in the region where the invention is applied. The invention may then reverse direction, placing (stretch) tension on the bypassed conductor section and the point of repair to assure its mechanical integrity. Mechanical bypassing only to temporarily shorten specific conductor spans may be achieved by the same device. Electrical bypassing only may be achieved in a similar manner by gripping and bridging two separate high voltage conductors, thus providing a means to connect and/or disconnect them with the aid of switching equipment incorporated into the invention. The invention allows all of the foregoing to be accomplished at line potential and in close line proximity by virtue of its being mounted on an insulated boom or suspended from a hovering helicopter or suspended from the line itself. | 04-16-2009 |
