Patent number: 4428106Abstract: Improved double wall tubing assembly which is especially useful in heat exchangers of the "coil-in-can" type for solar applications has a double wall construction which insures that a leak developing from a failure in either of the walls will not result in a mixing of fluid external to the outer tube with the fluid flowing internally of the inner tube. An outwardly projecting helical fin configuration formed on the outer surface of the inner tube provides an effective heat transfer medium between the inner and outer walls of the tube assembly while defining a spiral flow channel through which leakage entering through either wall can flow and be detected. A method of making the double wall tube assembly is disclosed wherein a finned outer tube is assembled over a previously finned inner tube. The assembled tubes are then brought into firm mechanical contact by the step of forming the assembled tubes into a coil and/or by expanding the inner tube.Type: GrantFiled: April 26, 1982Date of Patent: January 31, 1984Assignee: UOP Inc.Inventors: Bonnie J. Campbell, Thomas G. Counts, James L. Cunningham, Karl J. Youtsey

Patent number: 4196607Abstract: An improved drawing die apparatus is disclosed for reducing the wall thickness of a thin wall metal tube in cooperation with a floating pin or a fixed mandrel. At least three, and preferably four, wall thickness sensors are positioned in the die body in angular relationship around the outer periphery of a carbide draw die nib for indicating the wall thickness, and thus the eccentricity, of the tubing as it is being produced. Preferably, the sensors are contact type ultrasonic transducers which are acoustically coupled with a viscous couplant to flats formed on the draw nib in regions overlying a land region of the die. The acoustic coupling between the draw nib and tube is achieved through the O.D. drawing lubricant.Type: GrantFiled: April 3, 1978Date of Patent: April 8, 1980Assignee: UOP Inc.Inventors: Karl J. Youtsey, John M. Tatum

Patent number: 4079156Abstract: Conductive metal pigments which may be used in electrical devices are prepared by forming an alloy of a non-noble conductive metal and at least one oxidizable material, mixing the resulting alloy with a vitreous frit and an organic vehicle to form an ink, screening said ink onto a substrate, firing the alloy in an air atmosphere at a temperature in excess of about 500.degree. C. and cooling the ink to produce a conductive pigment. The oxidizable material is preferentially oxidized during the firing with a concomitant non-oxidation of the non-noble conductive metal.Type: GrantFiled: July 19, 1976Date of Patent: March 14, 1978Assignee: UOP Inc.Inventors: Karl J. Youtsey, Steven A. Bradley

Patent number: 4040929Abstract: Oxygen sensor incorporating a thin film electrolyte such as yttria stabilized zirconia sputtered onto a substrate produces an electrical signal in response to differences in oxygen partial pressures. The electrical signal changes rapidly enough for useful operation at temperatures which are substantially lower than those required by conventional oxygen sensors having a rigid, self-supporting thimble, tubular, or disc type electrolyte. For example, rapidly responding signals have been generated at temperatures below 200.degree. C whereas state of the art devices such as those used for sensing exhaust gases in automotive vehicles require temperatures higher than about 400.degree.

A preferred form of resistance element will cover the fibers in a quartz tube or other suitable encapsulating material to preclude moisture problems.Type: GrantFiled: October 8, 1974Date of Patent: August 3, 1976Assignee: Universal Oil Products CompanyInventors: Karl J.
