  • Patent number: 10398644
    Abstract: A medicant composition is provided. The composition includes a film layer and a powder matrix layer. The powder matrix layer includes a medicant. The powder matrix layer is applied to the film layer by admixing particulate to form a powder matrix and by then applying the powder matrix to the film layer by any desired method. The composition of the powder matrix is varied to alter the dissolution rate of the medicant, the adhesion of the medicant composition, and other physical properties of the powder matrix. The powder matrix layer can be cured.

  • Patent number: 9301397
    Abstract: Metalized web substrate is wet etched in a reaction vessel by contacting with oxidizing and metal complexing agent to remove metal from unpatterned region. Following etching, substrate is rinsed, and rinse is at least partly recycled. Concentrations of oxidizing and metal complexing agents in the etchant bath are maintained by delivering replenishment feeds of each. Concentration of metal in the etchant bath is maintained by discharging some of the etchant bath. Replenishment rates of oxidizing and metal complexing agents and etchant removal rate are determined based at least in part on rate that metal etched from the substrate enters the etchant bath.

  • Publication number: 20150174068
    Abstract: In accordance with a composition aspect of the invention, a composition for applying to skin comprises one or more pharmaceutically active ingredients contained in a plurality of hydrophobic carriers dispersed throughout a hydrogel, a skin permeation enhancer for enhancing the permeation of the active ingredients into skin, and an emulsifier. The amount of hydrogel is sufficient to allow the hydrogel to dry to as a substantially continuous film over and in contact with the skin to which it is applied. Related method and apparatus aspects are also described.

  • Patent number: 8901588
    Abstract: Disclosed herein are LED devices having lenses and methods of making the devices. The LED devices are made using an optical layer comprising a plurality of lens features. The optical layer is disposed relative to the LED die such that at least one LED die is optically coupled to at least one lens feature. A lens can then be made from the lens feature and excess optical layer removed to provide the device.
