  • Publication number: 20150144571
    Abstract: Techniques are described that relate to enhancing flocculation and dewatering of thick fine tailings, for example by reducing process oscillations. One example method includes dispersing a flocculant into thick fine tailings having a turbulent flow regime to produce turbulent flocculating tailings; subjecting the turbulent flocculating tailings to shear to build up flocs and increase yield stress, to produce a flocculated material having a non-turbulent flow regime; and shear conditioning the flocculated material to decrease the yield stress and produce conditioned flocculated tailings within a water release zone; and dewatering the conditioned flocculated tailings, for example by employing sub-aerial deposition. The thick fine tailings may have a Bingham Reynolds Number of at least 40,000 upon flocculant addition.

  • Publication number: 20040009313
    Abstract: Apparatus and method of manufacture therefor for containing heated substances without cover deformation. The apparatus has a container bottom and a lid member, where the container bottom has integrated within it a support structure such that when the lid member engages the container bottom, the support structure provides additional support to the lid member. The integrated structural support can be provided substantially at the area of the container bottom where the lid member, when attached, has relatively weak support at a predetermined temperature range.

  • Patent number: 5526656
    Abstract: A fiber string having a plurality of loops extending outwardly therefrom is formed by knitting a loop pile fabric with non-soluble and soluble yarns and then dissolving the soluble yarns in a solution to release the knitted loops. The loop pile fabric includes a central rib, or backbone, knitted from a plurality of non-soluble yarns, a plurality of loops knitted into the central rib such that terminal ends thereof extend outwardly from opposite sides of the central rib, and a strip of retaining fabric respectively knitted into the terminal ends of the loops on each side of said central rib. The loops are knitted from a plurality of non-soluble yarns, and the strips of retaining fabric are knitted from a plurality of soluble yarns. The retaining fabrics hold the ends of the loops during knitting. However, the loops are subsequently freed from the retaining fabric by immersing the entire fabric in a solution capable of dissolving the soluble yarns, i.e. the retaining fabric.
