  • Method for making plastic materials using recyclable plastics
    Patent number: 7081217
    Abstract: A method of making plastic materials, such as plastic lumber, wherein recyclable plastics are sorted into at least two categories and the recyclable plastics in each category are then shredded and chipped, extruded, and mixed with selected colour concentrates to produce the plastic materials of a selected colour. This invention allows for the control of the selected colour to enable replication of such colour of the plastic materials, regardless of any variation in colour of the recycled plastics in each category.

  • Magnetic paint composition and method
    Patent number: 5587102
    Abstract: A magnetic paint composition comprising a carrier, particulate magnetically permeable material, a binder, and a thickening agent having thixotropic and viscosity characteristics such that the paint composition has high viscosity when stationary, and low viscosity when shear forces to the paint composition, as it is being applied to a wall surface. When the paint is dried, magnetic objects can be mounted to the wall surface and held in place by the interaction by the magnetically permeable material.
