  • Patent number: 6096385
    Abstract: A magnetic disk having improved tribological characteristics in the data zone of the disk surface while retaining a low sliding stiction in the landing zone is disclosed. It contains the conventional elements of a substrate, a magnetic recording layer, a protective overcoat, and a lubricant layer on the protective overcoat. However, the lubricant layer is UV irradiated under a photo mask to cause a radially inner zone and a radially outer zone. The photo mask is designed so that the radially outer zone of the lubricant layer has a ratio of bonded/unbonded lubricant molecules greater than that in the radially inner zone. The reduced proportion of mobile lubricant molecules in the data zone prevents the lubricant molecules from being collected by the magnetic head. On the other hand, a large proportion of the lubricant molecules in the landing zone remained mobile. This allowed the sliding stiction in the landing zone to stay at the desiredly low value.

  • Patent number: 5800866
    Abstract: A method of preparing a dispersion of small particles in a polymeric precursor, which method involves providing a mixture of a particulate material and a surfactant in a nonaqueous solvent, forming a dispersion of the particulate material in the nonaqueous solvent, combining the resulting dispersion of particulate material in the nonaqueous solvent with a precursor material, and heating the combination of the dispersion of particulate material and the precursor material, with mixing, to a temperature sufficient to volatilize the nonaqueous solvent. The surfactant is soluble in the nonaqueous solvent and is adapted to stabilize the particulate material against agglomeration. The nonaqueous solvent swells the polymeric precursor near the boiling point of the nonaqueous solvent. The boiling point of the nonaqueous solvent is greater than a temperature at which the polymeric precursor may be mixed and below a temperature at which the polymeric precursor polymerizes or decomposes.

  • Patent number: 5750269
    Abstract: A removable coating composition comprises oxidized polyethylene wax, paraffin wax, and acrylic copolymer. A process of protecting surfaces comprises applying the coating composition in an aqueous emulsion to a surface and drying. The resulting coated surface is protected such that when graffiti is applied to the coated surface, the graffiti and coating are easily removed with hot water or steam.

  • Patent number: 5716662
    Abstract: For efficient waxing of the running surface of a workpiece such as a snowboard, one or more skis, or a toboggan, the invention provides a single wax-heating element in the form of an elongate flexible sheet sized to fully cover the running surface when upside down and horizontally oriented. The single sheet of the heating element also provides articulating connection between an array of like transverse elements which gravitationally load the heating element sheet into self-adapting conformance with flat and convexly curved features of the workpiece, so that a wax-laden sheet draped over the running surface of the workpiece can be gravitationally loaded by the heating element sheet.

  • Patent number: 5654039
    Abstract: Recyclable and compostable coated paper stock comprising a substrate coated on at least one surface with a primer coat and a top coat both of which are water based dispersions. The primer coat comprises a water based dispersion of a polymer selected from the group comprising acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, poly-ethylene vinyl acetate, poly-ethylene vinyl chloride, styrene butadiene copolymers, polyvinylidiene chloride or starch. The top coat comprises a water based dispersion of a polymer selected from the group comprising acrylic polymers, acrylic copolymers, styrene butadiene copolymers or polyvinylidiene chloride. In another embodiment the top coat further includes a wax component comprising 15-90 wt. % of the polymer and 5-85 wt. % of the wax. The substrate is coated with a primer coat prior to the application of the top coat to seal the substrate surface.
