Filed:

Feb 20, 1990

Appl. No.:

7/481693

Inventors:

Philip F. Finney - Villa Park IL

International Classification:

G01K 112
G01K 716

US Classification:

374208

Abstract:

An RTD assembly is welded directly to the heat receiving surface of a heat exchanger and shields the resistance element from the combustion gasses and thermally isolates the resistance element from the sheath of a sheathed cable which electrically connects the RTD to remotely located associated circuitry. The resistance element is maintained in direct contact with the heat receiving surface of the exchanger to provide an accurate measurement of the temperature of that surface.

Appl. No.:

8/926965

Inventors:

Philip F. Finney - Villa Park IL

International Classification:

B23K31/02

US Classification:

2281735

Abstract:

A temperature sensing device includes a head piece having a solid metal body with a mounting surface and a recess within the mounting surface for receiving a thermocouple therein. The body has an attachment end, and hole extending through the attachment end which communicates with the recess such that a plurality of leads may extend through the hole and connect to the thermocouple. A thermocouple may be made by first removing the sheathing and insulation from the end of a thermocouple cable, exposing the leads and the leads are flattened or other wise shaped. Also the diameter of such cables can be reduced by subjecting them to a drawing process or a swedging process wherein the outer diameter of the sheath of the cable is reduced as is the diameters of the alloy leads within the cable. To maximize the accuracy of the thermocouple, the junction at the end of the cable can be turned 90 degrees and the junction positioned within the enclosure to abut against the surface, the temperature of which is to be measured.

Philip F. Finney - Villa Park IL

Assignee:

Thermo-Couple Products Company, Inc. - Winfield IL

International Classification:

G01K 104

US Classification:

73359R

Abstract:

A surface thermocouple assembly including a metal sheath having thermocouple conductors extending therethrough in spaced relation from each other and from the sheath by electrical insulating material, an opening in the sheath wall at the hot junction end and through which the conductors are extended, a ceramic plug receiving the conductors and mounted in the opening, a fusion weld of the conductors outside the plug, and a V-shaped pad with a knife-shaped edge integrally formed at the junction end. The thermocouple is made from a length of sheathed thermocouple conductors by forming a keyhole slot at the junction end, removing the insulation around the conductors, bending the conductors through the opening of the keyhole slot, mounting a ceramic plug in place, fusion welding the ends of the conductors outside the plug to define the thermojunction, inserting a metal end plug at the junction end, welding closed the slot and the end plug in position, and building up a V-shaped welded pad at the hot junction end. Thereafter, mounting of the thermocouple assembly onto a surface for which the temperature is to be monitored includes the positioning of the hot junction end onto the tube with the knife-shaped edge of the pad in engagement with the tube, and providing void-free welds between the pad and the tube such that the distance between the thermojunction and the tube surface is substantially less than the distance between the junction and the closest free surface of the mounting welds.

Appl. No.:

Inventors:

Philip F. Finney - Villa Park IL

International Classification:

H01L 3502

US Classification:

136233

Abstract:

A thermocouple assembly for attachment to surfaces by welding which includes a solid metal head formed with a knife edge and receiving sheathed thermocouple conductors, the ends of which are disposed at the knife edge and are junction welded. The head is economically fabricated on a mass-production basis, and the sheathed conductors are attached in a simple manner to minimize the overall production costs of the assembly. The disposition of the junction and the connection between the sheath and the solid head coacts with the weldments mounting the assembly on a surface to control the heat energy path such that the effective junction permits the junction to accurately function with respect to sensing the temperature of the surface on which the assembly is mounted.

Abstract:

A seal assembly for providing a seal between the hull of a powered water craft and a drive shaft which passes through the hull includes a flexible tubular boot which is attached to a through-hull fitting which is affixed to the hull and is attached at its other end via a leak-proof seal to the shaft at a location within the hull. The shaft seal assembly includes a pair of mutually engaging annular face seal members with one of the seal members being affixed to the fitting and the other being affixed to a sealing collar which is adjustably positioned along the shaft.

International Classification:

H01L 3502

US Classification:

136229

Abstract:

An improved thermocouple and method for making the thermocouple and installing same on the fireside of heat exchanger tubes or the like for monitoring surface temperature which includes a thermocouple assembly made from mineral oxide insulated metal sheathed thermocouple wires where a pair of thermocouple wires or conductors extend through a metal sheath in spaced apart and insulated relation from each other and from the sheath and are connected together at an end to define a hot junction member adapted to be mounted in engagement with the surface being measured, which hot junction is defined by a disk or bar-shaped member extending from the end of the sheated conductor assembly beyond the insulation and sheath but not in contact with the sheath. Installation on a heat exchanger tube includes welding the sheath to the tube which pressurizes the hot junction against the temperature measured surface and defines a heat energy path that bypasses the hot junction.
