Patent number: 6218840Abstract: The present invention is a means of allowing continuous radio detection of underground utilities while maintaining cathodic insulation of metal utility conduits such as gas mains and pipes. By using a capacitor between a metal gas main and an old metal gas service line, the gas main is isolated from the service line. A short in the tracer line against the old metal gas service line will not result in an electrical connection with the metal gas line that increases the rate of deterioration of the cathodic protection anode. Using the capacitor in the tracer wire system eliminates check points isolating tracer wire sections. In the preferred embodiment of the present invention, the capacitor assembly comprises a ceramic nonpolar capacitor ranging from 0.01 microfarad to 1.0 microfarad encased in an epoxy plastic contained in a case. The tracer wire leads are of 14 gauge oxygen free copper.Type: GrantFiled: May 8, 1999Date of Patent: April 17, 2001Inventor: John Fridy Warren

Patent number: 5589666Abstract: A buried service splice enclosure for sealing a splice of telecommunication cables comprises a closure defining an interior space for accommodating the cable splice and defining an opening for receipt of the splice therethrough. A closure seal sealably closes the closure opening and has apertures for receipt therethrough of the cables. Means are provided for sealing the closure seal to the closure and for sealing the cables to the closure seal at the apertures. An inlet fitting, such as a check valve, communicates with the closure interior space and is adapted to receive and pass an encapsulant under pressure into the interior space. An outlet fitting, such as a pressure relief valve, also communicates with the interior space, the pressure relief valve adapted to pass the encapsulant therethrough when the encapsulant is exposed to a predetermined pressure in the closure interior space.Type: GrantFiled: April 30, 1993Date of Patent: December 31, 1996Assignee: Thomas & Betts CorporationInventors: David J. DeCarlo, Thomas L. Mineur, Ronald S. Stanwick

Patent number: 5541362Abstract: The invention refers to a height and azimuth alignment adjustments assembly which is utilized for the precise and simplified adjusting of the heights of embedded containers and for the aligning of its light fixture with respect to a straight line. These containers are installed in airport runways, taxiways and other aircraft traffic areas to serve as bases for lighting fixtures, transformer housings and junction boxes. The adjustments take place both, when the containers and their lights are initially installed as well as when the runways, taxiways and other aircraft traffic areas are resurfaced.Type: GrantFiled: January 8, 1993Date of Patent: July 30, 1996Inventor: Gary L. Reinert, Sr.

Patent number: 5401902Abstract: A reentrable moisture barrier for use in enclosures for cables and or cable components to prevent entry of ground moisture is disclosed. The barrier is inexpensive and easy to install. One example of the invention is in conjunction with an enclosure or housing with a first cover portion removable from a second base portion. The improved reentrable moisture barrier is formed of an inexpensive flexible sheet which may be deformed and replaceably inserted in the enclosure to prevent ground moisture from migrating from the open bottom of the housing to the top of the first cover portion where it may condense and be deposited on the cables and cable components. The reentrable barrier is wrapped around and stuffed between the cables and the interior of the second base portion and the first cover portion is replaced. Ground moisture is thus prevented from reaching the interior of the first cover portion.Type: GrantFiled: January 26, 1993Date of Patent: March 28, 1995Inventors: John S. Middlebrook, James P. Ryan

Patent number: 5384427Abstract: A flood protection pedestal protects telecommunications equipment and the like retained therein from water damage during flood conditions in the surrounding environment. The flood protection pedestal includes a base assembly, a structural cover assembly removably attached to the base assembly for covering the telecommunications equipment, and an air entrapping arrangement inside the cover assembly over the telecommunications equipment. The air entrapping arrangement may be either a thin walled unitary dome member integrally formed of a plastics material or a coating applied to the interior of the cover assembly. A downwardly oriented opening is formed in the dome member for receiving telecommunications equipment. A body of air is entrapped within the cover assembly when flood waters rise above a given level for protecting the telecommunications equipment from exposure to the flood waters.Type: GrantFiled: September 20, 1991Date of Patent: January 24, 1995Assignee: Reliance Comm/Tec CorporationInventors: Thomas G. Volk, Matthew Leschinger, Jimmy W. Parkerson

Patent number: 5367127Abstract: A device is provided for use in maintaining organization of lines which pass through a trench. The device includes a thin, substantially planar foundation and at least one separating member projecting normally therefrom. The foundation is suited for placement within a trench to directly underlie lines. The separating member is operatively associated with the foundation, acting as a spacer between adjacent lines. In order to provide a readily transportable and storable device, the invented line organizer is constructed from a single, thin sheet of generally rigid material. The sheet is foldable to provide a generally triangular device.Type: GrantFiled: May 29, 1992Date of Patent: November 22, 1994Inventor: William B. Dormon
