  • Patent number: 5375350
    Abstract: An excavating tool tooth includes a mounting area (10) and a working area (11). The working area (11) includes longitudinal bars (14-18) made of a hard material. The bars are inserted in the steel and snugly contact the tooth's cutting face. The presence of the rods made of a hard material substantially increases the tooth's service life. The bars are produced by infiltration.

  • Patent number: 5261170
    Abstract: A wear strip (A) for use on material handling equipment, such as chutes, plough blades, scrapers and gates, comprises an elongate body (30) of metal of substantially rectangular cross-section, and wear resistant tiles (31) bonded to the body and extending across one face (32) from at least one edge (33), the tiles being spaced along the body which is provided with slots (34) in alignment with the gaps (36) between the tiles (31), to make it possible to bend the strip (A) to suit the curvature of say a plough blade or a scraper to which the strip can then be "stitch" welded and readily removed (when worn) by a cutting torch or an angle grinder. Other wear strips (B and C) have, respectively, further tiles on an adjacent face, and a cross-section of substantially right-angled triangular form.
