Abstract:
Reactive inks and methods of generating an image on a substrate using both reactive and heat activated inks are presented. An image is printed on a substrate, without reacting the reagents in the ink. Subsequently, the reagents are reacted to fix the image to a substrate, with substantial permanency and fastness. Sublimation or similar heat activated dyes are printed are also printed on the substrate. The sublimation or similar heat activated dyes are activated, and have an affinity for polymer that is applied to the substrate.

Abstract:
Delivery systems for incorporating functional compounds into substrates for use in various consumer products are disclosed. Specifically, the delivery system includes a carrier component comprising an ultrasonically energized adsorbent and one or more functional compounds. The ultrasonically energized adsorbent can adsorb the desired functional compounds and bind the functional compounds to the surface of the substrate.
Abstract:
A color image is digitally printed onto an intermediate transfer medium. The image is subsequently transferred from the intermediate transfer medium to a final substrate, which may be a cellulosic textile, such as cotton. Bonding of the color images is provided by the reaction between compounds selected from each of two chemical groups contained in the intermediate transfer medium. The first group comprises compounds with functional groups capable of reacting with active hydrogen, such as isocyanate or epoxy groups. The second group comprises compounds with functional groups containing active hydrogen, or compounds with functional groups containing active hydrogen after a conversion process. The functional groups of one or both reactive chemical groups may be protected either by blocking with internal or external blocking agents or by a physical barrier such as encapsulating agents. The blocking agents are removed by the application of energy, such as heat, during the transfer of the image from the intermediate transfer medium to the final substrate. The intermediate transfer medium may be comprised of additional components which may be combined with either or both of the above two chemical groups, or applied as separate layers. Examples of such components are a thermally expandable material, an exothermic chemical, a release agent, and/or absorbent material. Transferred images so produced have a soft hand, particularly when applied to a textile, and excellent fade and abrasion resistance.
Abstract:
Ultrasonic treatment method and system for separating compounds in an aqueous effluent is disclosed. More particularly, the ultrasonic treatment system uses ultrasonic energy to energize adsorbent to provide efficient and effective removal of compounds from aqueous effluents, such as textile effluents.
Abstract:
A method for rapidly assessing upper respiratory conditions is provided. More specifically, the method involves contacting a sample obtained from the upper respiratory tract of a host with a test strip. The test strip contains an indicator that provides a broad spectrum response in the presence of bacteria, mold, yeast, or other microorganisms that is different than its response in the presence of viruses. This allows for a rapid and simple assessment as to whether the test sample is infected with a virus or some other microorganism. To help a clinician identify the proper course of treatment, it may also be desirable to obtain further information about the particular type of microorganism present. In this regard, the test strip contains any array of one or more differentiating indicators that provides a certain spectral response in the presence of different types of microorganisms. For example, the array may provide a certain spectral response in the presence of gram-negative bacteria, but a completely different spectral response in the presence of gram-positive bacteria. Likewise, the array may provide a certain spectral response in the presence of Rhinoviruses (associated with the common cold), but a different response in the presence of Influenza viruses. Detection of the spectral response provided by the indicators may thus allow for rapid differentiation between different types of microorganisms.
Abstract:
A method for detecting a microorganism or class of microorganisms is provided. More specifically, the method employs an array that contains a plurality of discrete regions (referred to as "addresses") spaced apart on a solid support in a predetermined pattern. The addresses are selected so that the array provides a distinct spectral response (e.g., pattern of colors) or "fingerprint" for a particular microorganism or class of microorganisms. For example, the array may provide a certain spectral response in the presence of one microorganism or class of microorganisms (e.g., gram-negative bacteria), but provide a completely different spectral response in the presence of another microorganism or class of microorganisms (e.g., gram-positive bacteria). Detection of the spectral response provided by the array may thus allow for differentiation between microorganisms.
