    摘要: A tape measure includes a guide at the end of the free end of the measurement tape that seats a marking instrument in a perpendicular orientation with respect to the tape and disposes the center line of the marking instrument aligned with the end of the tape. The tape measure may include at least one sharpener incorporated in its housing. The guide, or other attachments for the end of a tape measure, may include measurement markings on its upper surface aligned with measurement markings on the tape to permit precise measurements to be taken at the very end of the tape.

    摘要: A molded, non-metallic insert is disclosed that is of a form which replicates the seat configuration of the oxy-fuel cutting torch into which it is intended to be inserted. The insert material is compressible and resilient and allows a cutting tip, without special requirements, to be installed into the cutting torch so equipped with the insert. The insert is resistant to the difficult environmental conditions in which it is required to operate, in the industrial situations in which it is used. The insert resists elevated temperatures and the chemical and physical effects of the gases it contacts while sealing the flowpaths of the oxygen and fuel flowing through the torch head and cutting tip.
