Abstract: A finned tube for a heat exchanger has an inner surface in which is provided raised portions which are in rows and extend in the longitudinal direction of the tube. The raised portions are arranged, within each row, at irregular intervals and each raised portion may either increase or decrease toward a radially inward tip. The raised portions may have a cross-section which is substantially triangular or trapezoidal or in the shape of a parallelogram and lateral surfaces of the raised portions, together with the internal surfaces of the tube are roughened during drawing. In a process of making such a tube, an unhardened tube having a plurality of circumferentially disposed longitudinally extending fins is drawn through a die so as to subject the tube to a cross-sectional decrease of at least 50% to thereby fragment the fins to provide gaps between remaining raised portions of the fins. A drawing die for use in the process has an entry angle .alpha..gtoreq.40.degree..

Abstract: A machine for performing double exposure, interferometric analysis of the changes in an object surface that result from changes in the ambient pressure on the object, as by holography, includes a pressure chamber partially formed by a horizontal base operative to support the test object and interferometric camera on its upper surface. A semispherical pressure dome is placed on the base over the test object and camera. A manifold volume bounded by a thin resilient steel disc supported beneath the base plate on a rubber gasket has its pressure equalized with the area beneath the dome by passages formed beneath the base plate. When the pressure is changed beneath the dome a similar pressure change occurs in the manifold volume beneath the base so that no net pressure forces are exerted on the base plate and no deformation of the camera or test object occurs.

Abstract: An inflation anchor for sealing a conduit bore. A tubular elastomeric bladder is attached to a shoe assembly, with two layers of calendered steel cable being fixed to the shoe assembly and surrounding the bladder. At the free end of the bladder, an elastomeric cup is bonded thereto and overlaps the layers of cable. In operation, a valve is closed between the interior and exterior of the anchor, and fluid pressure increased in the conduit. The initial seal is made by the trailing cup edge expanding to firmly contact the conduit wall, after which the remainder of the cup expands into contact with the wall, and the tubular bladder subsequently expands as pressure is further increased, pressing the cable into frictional engagement with the conduit wall.
