Patent number: 9704674Abstract: A fuse holder for a fuse cutout includes a molded member including a short fuse tube section and a downwardly extending fin member adapted for securing to a trunnion assembly. An arc quenching liner is disposed in the interior of the tube section and a top casting is connected to the top of the fuse holder and adapted to receive and hold an arc flange of an arc sleeve on a top edge, thereby keeping the arc flange above the top casting. A conductive screw cap seals the assembly. The shorter tube and the provision of the arc flange above the top casting provides superior arc quenching properties.Type: GrantFiled: July 14, 2014Date of Patent: July 11, 2017Assignee: Hubbell IncorporatedInventors: Jeffery Joseph Kester, Lloyd Ronald Beard, Sterlin Cochran, Bryant Haines, Charles Worthington

Publication number: 20070213019Abstract: An improved receiver architecture and method for a wireless transceiver (e.g. for a headphone) is provided whereby the receiver, advantageously, enables the use of only one synthesizer circuit for both the RF-to-IF and IF-to-base band conversion processes which, in turn, provides for lower power consumption. The receiver includes an injection locked local receiver oscillator (Rx LO) which is used for the first mixing stage (i.e. the RF-to-IF conversion). The Rx LO 105 is thereby able to use a high-level harmonic of a relatively low reference frequency signal produced by that synthesizer (e.g. a fractional-N phase locked loop circuit (PLL)). The receiver further includes a tunable Q-enhanced IF filter 110 and complex sub-sampling and mixing down-conversion circuitry for the second conversion stage (i.e. IF-to-baseband conversion). The sampling frequency used for the second conversion stage is a harmonic of the reference frequency derived from the synthesizer (PLL).Type: ApplicationFiled: March 13, 2006Publication date: September 13, 2007Inventors: Christopher Devries, Ralph Mason, Ronald Beards

Patent number: 5650728Abstract: A system comprising a portable apparatus and employing a method of admittance versus frequency analysis to detect the existence of a fault in a de-energized electrical line regardless of whether the line contains branches. The portable apparatus comprises a capacitor unit detachably connected to a de-energized line, ground or a neutral conductor, a switch unit detachably connected to a de-energized line, the de-energized line being tested, and an insulated cable connecting the capacitor unit to the switch unit. The switch unit comprises a discharge switch that can be activated by pulling on the hot line tool. The capacitor unit comprises a capacitor which is discharged into the electrical line via the insulated cable and the switch unit when the discharge switch is activated to create a pulse.Type: GrantFiled: April 3, 1995Date of Patent: July 22, 1997Assignees: Hubbell Incorporated, University of MissouriInventors: David Adelbert Rhein, Lloyd Ronald Beard, Gerald Bernard Roberts, Thomas Jude Herrick

Patent number: 5281767Abstract: An improved, failure-resistant, low mechanical stress electrical connector bushing (10) is provided which includes an elongated, central metallic conductor rod (12) with an insulative epoxy body (14) cast about the central rod (12). The rod is of substantially constant diameter throughout its length, and includes a male connection end (16) and an opposed female connection end (18). The connection end (18) presents an upset, integral, cold-forged, radially expanded terminal portion (20) having a diameter greater than the constant diameter rod (12), and presents a butt end face (24). Stress analysis confirms that the bushing (10) develops reduced, mechanical thermally induced stresses, as compared with a prior design.Type: GrantFiled: October 30, 1992Date of Patent: January 25, 1994Assignee: A.B.

Patent number: 3958205Abstract: A lightweight, compact, conductor-mounted open link fault interrupter having mounting means permitting suspension thereof directly from an overhead power line without the need of cumbersome pole-mounting structure. Pinwheeling and flashover problems heretofore encountered during operation of conductor-mounted, closed link interrupters are precluded by virtue of the open link, fusible element employed since through use thereof no net rotational forces are imparted to the interrupter during its operation. The interrupter hereof provides especially advantageous protection when electrically connected in series with a unique high range current limiting fuse capable of safely interrupting high magnitude fault current to insignificant values substantially ahead of the first natural zero point.Type: GrantFiled: December 23, 1974Date of Patent: May 18, 1976Assignee: A. B. Chance CompanyInventors: Lloyd Ronald Beard, Allen Houpt Knepper
