    • A heated flowline electrical isolation joint is disclosed for introducing current into a pipe-in-pipe system having an outer and an inner pipe. A hub presents a load flange having tension and compression load shoulders on its terminal end and connects to the inner pipe on its other end. An end flange presents an end flange load shoulder on one end and a high strength, highly electrically insulative first ring separates the compression load shoulder from the end flange load shoulder which engage therethrough in a load bearing relationship. A plurality of o-ring seals secure the compression load shoulder-to-first ring-to-end flange load shoulder interfaces. A retainer flange connects to the end flange on one end and to the outer piper on the other end, encircling the hub and presenting a retainer flange load shoulder. A second high strength, highly electrically insulative ring separates the tension load shoulder of the hub from the retainer flange load shoulder which engage therethrough in a load bearing relationship. A plurality of o-ring seals securing the tension load shoulder-to-second ring-to-retainer flange load shoulder interfaces. An electrical feedthrough tubes receives an electrical penetrator which reaches through the retainer flange to electrical connection with the hub. An electrically insulative material in the annulus between the hub and the retainer flange and between the electrical penetrator and the electrical feedthrough tube secures electrical isolation across non-load bearing areas.

    • The automatic tire inflation status measurement system comprises a scale and a tire-deformation apparatus for automatically determining whether a pneumatic tire installed on a vehicle is underinflated. The scale plate is flush mounted with the road surface and measures the weight on the tire as the tire rolls across the plate. A second weight measurement is made by using a deformation bar which projects slightly above the road surface and causes the tire to deform as it rolls over the bar. Both the scale and deformation bar are connected to load cells, preferably the same load cells. The tire deforms as it rolls across the bar and weight on the bar vs time is measured by the load cells. Data from the load cells is collected by, for example, using a summing amplifier and a computer-operated data acquisition board. The peak reading on the scale and the peak value of the bar reading are used to calculate a ratio. This ratio is then compared to a threshold value to determine whether the tire is underinflated. The result of this analysis is communicated to the vehicle driver, for example, by an electronically controlled display, such as a visual message display, computer speech generator or printer output, connected to the computer.

    • A method for installing an offshore pipeline is disclosed in which the inner and outer pipes are structurally connected at a terminal end of a pipe-in-pipe flowline and centralizers are placed in the annulus to provide lateral support and maintain concentricity between the two pipes and to prevent buckling of the inner pipe. The working end of the pipeline is suspended under construction in a substantially vertical position within slips at the weld floor of a J-lay installation barge and sections of inner and outer pipe are added. Inner pipe is added by sections by grasping and orienting the section of inner pipe to a vertical position and the section is brought into abutting position with the inner pipe at the working end of the pipeline under construction, welded in place, and the weld is coated with an arc resistant material. Sections of outer pipe are added by grasping and reorienting to a vertical orientation, sliding the section down over the section of inner pipe just welded in place, bringing the section of outer pipe into abutting position with the working end of the pipeline under construction and welding it into place. The working end of the pipeline is then advanced through the slips to bring the end of the section of outer pipe added adjacent the weld floor and the foregoing steps are repeated as necessary to add additional sections of inner and outer pipe to complete the pipeline.
