Abstract: A method of salvaging a pipe conduit which is buried under ground, especially a sewer pipe, includes soaking a resin-absorbing inner layer of a lining hose, which further includes an impermeable outer layer that outwardly adjoins and surrounds the inner layer, with a first resin. The lining hose is then placed into the pipe conduit. A surface region of a calibrating hose which is to contact the inner layer of the lining hose is provided with a layer containing a second resin. The lining hose is then shaped to conformingly line the pipe conduit. Such shaping involves introducing the calibrating hose into the lining hose in such a manner that the resin-containing layer of the calibrating hose contacts the inner layer of the lining hose and pressing the calibrating hose against the lining hose to urge the latter against the pipe conduit. Finally, at least one of the first and second resins is hardened.

Abstract: A contact for a multicontact probe assembly for testing at least partially conductive elements has a conductive contact rod extending along a axis and having a rear end and a forwardly directed and pointed front test end of construction suitable for using alone as a test point. A respective conductive cap engageable axially snugly over the pointed front end of the rod can be releasably secured on the pointed front end for use of the same rod to test, for example, a bushing or a bore connection. Thus a single contact can serve several functions, making the probe assembly having it much more versatile than prior-art systems. Only some of the contact rods of a probe assembly, those destined to engage large-diameter bores or bushings, need be equipped with the heads, and the small pointed tips of the remaining rods of the assembly can engage and contact the strips or smaller holes or bushings directly.
