Abstract: An element removal tool for use with transmission lines for fluids (such as natural gas) under pressure which permits replacement of the element, in a specific case the axle box which is coupled between a metering chamber and the indexing mechanism in a gas meter, in a fluid transmission system, without shutting off downstream-customer service, the problem of properly seating the axle box in the undergear which drives it, despite slow rotation of the driving mechanism in the metering chamber, being overcome by dual concentric shafts relatively rotatable and slidable with respect to each other, the inner shaft carrying a socket which engages, firmly, the rotatable indexing shaft of the axle box, the outer shaft carrying a socket which is adapted to firmly engage the flange of the axle box for removal and replacement of the axle box, each shaft having at its end remote from its respective socket, a knob for rotating that shaft, the outer shaft passing through and hermetically engaging a stuffing box, connected

Abstract: To assist in locating an underground or otherwise hidden non-electrically-conducting plastic pipe carrying a fluid such as heating gas a tool is provided which comprises a reel of relatively stiff but flexible locator wire, a hermetically-sealing first bushing through which the locator wire passes and a coupler for engaging a pipe exposed to view but coupled to and communicating for fluid flow with the pipe to be located, such coupler being adapted to receive, in snug fashion, said first bushing and including a packing membrane through which said locator wire passes to further assure no loss of fluid from the pipe being located, said locator terminating at its extremity remote from the reel in a guide member having a shape which may be described as suggestive of an oblate spheroid; i.e.
