  • Publication number: 20030008112
    Abstract: The present invention relates to ink-jet transfer media that can be printed with images using ink-jet printers. The printed image can be thermally transferred to fabric materials such as such as black or white colored T-shirts. The ink-jet transfer media of this invention comprise a support paper containing independently removable panels. Each removable panel is capable of being peeled away from the film coating. The removable panels are divided by means of a peel line in the paper.

  • Publication number: 20020192434
    Abstract: The present invention relates to ink-jet transfer papers that can be printed with images using ink-jet printers. The ink-jet printable transfer papers comprise a support paper having a surface coated with layer (a) and ink-receptive layer (b). Layer (a) comprises a polyurethane binder and inorganic pigment, and layer (b) comprises a polyurethane binder and organic polymeric particles. The printed image can be heat-transferred to fabric materials particularly dark-colored fabrics such as black T-shirts.

  • Publication number: 20020039757
    Abstract: The present invention is an enzymatic method and diagnostic kits for detecting and quantifying the presence of one or more lysophospholids in a sample of bodily fluid taken from a test subject. The method uses enzymes in a two step assay and may be used to detect disease conditions associated with altered levels of lysophospholipids and to correlate such conditions with altered levels of lysophospholipids.

  • Patent number: 4731539
    Abstract: Method and apparatus for introducing normally solid metals or metalloids into electrically conductive substrates. The invention is particularly useful in surface alloying of metal substrates and makes it possible to introduce metals into ferrous metal substrates to depths of 200 microns and more. The metal or metalloid to be introduced is maintained at an elevated temperature below the boiling point, the surface portion of the substrate is maintained at an elevated temperature below the deformation point, and a double glow discharge is employed under controlled conditions to transfer the metal or metalloid to the substrate.

  • Patent number: 4520268
    Abstract: Method and apparatus for introducing normally solid metals or metalloids into electrically conductive substrates. The invention is particularly useful in surface alloying of metal substrates and makes it possible to introduce such metals as tungsten into ferrous metal substrates to diffused depths of 100 microns and more without undue expense. The metal or metalloid to be introduced is maintained at an elevated temperature below the boiling point but equal to at least 40% of the melting point, the surface portion of the substrate is maintained at an elevated temperature below the deformation point, and a double glow discharge is employed under controlled conditions to transfer the metal or metalloid to the substrate.
