Abstract: A pipe tapering device adapted to receive the outer peripheral marginal end of a tubing or pipe therewithin and to grind a circumferentially extending taper on a marginal end of a pipe. The apparatus is particularly suited for forming a taper on the outer surface of the marginal end of fiberglass or plastic pipe. The apparatus is adjustable and can be employed to taper the ends of a number of different size pipe diameters. The apparatus is hand held and can be powered by an ordinary drill motor.

Abstract: A probe-type electrical identifying device for identifying individual conductors in a multiple conductor group such as in a cable or extending through a conduit pipe, including a conductor indicator probe and voltage supply unit, wherein the probe has a pair of light emitting diodes (LEDs) of different color and is capable of distinctively identifying as many as five individual conductors in the group. Connector leads having alligator clamps are provided to connect to the individual conductors at one end. The voltage supply unit has switches assigned to five of the connector leads and electrical circuitry is provided to enable distinctive identification of the five different conductors by different activation of the two LEDs in the probe.
