  • Tire sidewall deformation detection techniques
    Patent number: 4475384
    Abstract: An improvement in a tire manufacturing system including means for testing the extent of sidewall deformation of a tire. The tire is rotated and measured for lateral runout of both sidewalls. The resulting data is converted to digital form and analyzed by groups in order to increase the accuracy by which unacceptable sidewall bulges and valleys are detected.

  • Hose structure
    Patent number: 4474217
    Abstract: Hose structure suitable for transport of highly abrasive media including at least two concentric tube layers of elastomeric material. The radially innermost tube layer material is of greater abrasion resistance than a tube layer radially outwardly thereof. A radially outer tube layer material is of greater resilience than that of the radially innermost tube layer. The tube layers may be made visually distinguishable, for example, by being of different colors, so as to serve as a wear indicator.
