Each conductor pair has two conductors of dissimilar materials joined at a unique junction point along the sheath. The unique junction points permit sensing of temperature at different locations along the length of the multipoint thermocouple.Type: GrantFiled: April 26, 2001Date of Patent: April 22, 2003Assignee: Daily InstrumentsInventors: Jeffrey N. Daily, Robert F. Poteet, Michael W. Rahn, Larry D. Welch

Patent number: 6239351Abstract: A self-diagnostic thermocouple (10) having a first (12), a second (14) and a reference (16) thermoelement enclosed in a sheath (20) filled with an insulator (18) separating the thermoelectric elements from each other and the sheath. The three thermoelements (12,14,16) are joined at a common location to form three separate thermocouple junctions (22) having three distinct electrical outputs as a function of temperature. The reference thermoelement (16) is made from a pure metal or alloy which has stable thermoelectric characteristics. Deterioration of the electrical output of the self-diagnostic thermocouple (10) is capable of being detected by a programed microprocessor (100).Type: GrantFiled: July 19, 1999Date of Patent: May 29, 2001Assignee: Hoskins Manufacturing CompanyInventor: Bertie Forrest Hall, Jr.

Patent number: RE49027Abstract: A cable gripping and tensioning apparatus is provided for attaching a cable to an anchor point such as a wooden post as part of a cable railing system. In one form, the apparatus includes a tubular component and a ferrule. The tubular component includes external threads to engage the wall of a hole in the post, an internal axial bore through which a cable may pass, a first end which may engage a wrench to rotate the tubular component and a second end which may provide a thrust bearing surface. The ferrule is swaged to an end portion of the cable. The ferrule provides a thrust bearing surface for contact with the second end of the tubular component, allowing for the rotation of the tubular component to tension the cable while the cable does not rotate.Type: GrantFiled: February 23, 2021Date of Patent: April 12, 2022Inventor: Edwin Lee Henderson
