  • Publication number: 20040238663
    Abstract: A first rigid body has a horizontal surface on which a composite is to be placed and a non-horizontal surface on which the composite is not to be placed, with the horizontal surface and the non-horizontal surface forming a continuous horizontal linear edge. The continuous horizontal linear edge has a first portion, which is an edge of the non-horizontal surface, and a second portion, which is an edge of the horizontal surface, and the composite has a first region provided with a first member and a second region provided without the first member. While the composite is placed so that the first portion corresponds to the first region or the first region and a part of the second region and that the second portion corresponds to the remaining second region, the composite is separated by moving down a second rigid body from above the substrate.

  • Patent number: 5797547
    Abstract: A superior grade of flake mica product may be produced by applying shear forces to sedimentary mica to delaminate it into flakes. Shear forces are applied by rotating a plurality of arcuate blades within a confined cylindrical chamber containing the mica, such that the mica is forced between an outer portion of each blade and the chamber. Each one of the arcuate blades is curved to define an end portion that is spaced from, and substantially concentric with, a portion of the cylindrical chamber.

    Abstract: An abandoned or inactive portion of an asbestos open pit or underground shaft mine is used to permanently bury asbestos waste material produced from asbestos mining, asbestos processing and building demolition or renovation. The asbestos waste material is deposited in the mine, preferrably, in sealed containers and covered with tailings or non-asbestos material, such as soil or the like. As the asbestos waste material is deposited in the mine, it is covered with a layer of tailings or non-asbestos material within any twenty-four hour period. This procedure is repeated until the mine if filled and ultimately covered with a layer of non-asbestos material. A layer of vegetation is then planted on top of the former mine site.
