John E. Mahn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6241841
    Abstract: A heat activated transfer is formed having a lower thermoplastic or thermoactive adhesive layer, an upper transparent thermoset layer and indicia. The indicia is formed from sublimation dye or diffusion dye which is heat transferred into the thermoset material, preferably as the heat activated transfer is being applied to a cloth substrate. This permits printing and application of individual unique indicia on each individual heat activated transfer at a very low cost. Due to the extreme clarity of the formed product as well as the ease by which different unique indicia can be provided with each heat activated transfer, this method and product is uniquely suitable for use in preparing coated machine-readable indicia such as bar codes. This permits inventory control for cloth items such as hospital garments, linen and the like. It also permits uniforms and the like to be marked with the individual user's name at a relatively low cost.

  • Patent number: 5480506
    Abstract: An ornamental heat transfer is described which is especially adapted for application to nylon fabrics. The ornamental heat activated transfer includes an upper layer which is generally a thermoset layer, cloth such as twill or flock which is bonded to a lower layer. The lower layer is an uncured linear saturated polyester film which includes a heat activatable isocyanate curing agent. Upon application of the transfer to nylon the transfer is heated which melts the uncured saturated polyester and activates the curing agent. Thus while the linear saturated alkyl polyester is in a molten state the curing agent causes the polyester to cure in tight confinement with the nylon fabric.

  • Patent number: 4786349
    Abstract: The present invention is a method of applying a heat activated transfer to a cloth substrate. The transfer includes a thermoplastic adhesive layer and printed thereon a thermoset ink layer. The thermoset ink layer is discontinuous leaving exposed areas of thermoplastic material. The transfer is applied by setting the thermoplastic layer against a substrate, such as a cloth shirt, placing a piece of blotting paper or other absorbent material above the transfer in contact with the thermoset layer and applying heat and pressure forcing the thermoplastic material to melt. The thermoplastic material which contacts the blotting material is absorbed by the blotting paper whereas the thermoplastic material covered with the thermoset ink absorbs into the substrate bonding the thermoset ink to the substrate providing an emblem or the like.

  • Patent number: 4610904
    Abstract: A heat activated decorative includes a lower thermoplastic layer and an upper layer which is a thermoset ink. The decorative is suitable for use on clothing which is laundered in industrial laundries wherein the wash cycle subjects the garments to pHs greater than 10 and the dryer subjects the garments to ambient temperatures of 400.degree. F. and momentary contact with the dryer drum wall which is about 500.degree. F. The lower thermoplastic layer is a high melt thermoplastic having a melting point of at least about 380.degree. F. and the upper layer is a thermoset ink which has a thickness effective to protect the thermoplastic layer from the effects of the industrial laundry and specifically about 25 microns in thickness or more. The decoratives of the present invention can be in the form of machine readable bar codes to provide a method of sorting rented garments.

  • Patent number: 4423106
    Abstract: A laminated material is formed of a layer of polyurethane or polyether and a layer of extruded polyester. The polyester adhesive layer, which may contain five to fifteen percent by weight of polyurethane homogeneously mixed therein, is bonded to the layer of polyurethane or polyether under pressure at a sufficiently high temperature to permit an even viscous molecular flow between adjacent surfaces of the layers. When the layer is polyurethane, the temperature is above the softening point of polyurethane so that it is high enough to remove at least enough of the toluene solvent from the layer of polyurethane so that curling is prevented. When the laminated material is applied to a material with sufficient pressure and heated sufficiently that the layer of polyester becomes adhesive, the laminated material adheres to the material against which the layer of polyester is pressed.

  • Patent number: 4390387
    Abstract: A flocked material is formed of a first layer of a thermoset acrylic copolymer cross-linking water base adhesive having polyester or rayon flock fibers extending from one surface and a second layer of an amorphous thermoplastic polymer adhesive bonded to the other surface. The polymer adhesive is a homogeneous mixture of polyester and polyurethane or of polyamide and polyurethane. When the flocked material is applied to a material with sufficient pressure and heated sufficiently that the layer of polymer adhesive becomes adhesive, the flocked material adheres to the material against which the layer of polymer adhesive is pressed. Thus, the flocked material has particular utility as a letter, numeral, design, or silk screen print product for a sport uniform or wearing apparel, for example, of any material.
