  • Patent number: 10027076
    Abstract: A current carrying system for use in transporting electrical current between a plurality of electrical devices is provided. The current carrying system includes a busbar having a first axial end, a second axial end, an electrically conductive shaft extending from the first axial end to the second axial end, and at least one cooling feature defined in at least a portion of the electrically conductive shaft. The current carrying system also includes a casing that defines a busbar channel configured to receive the busbar such that the casing at least partially circumscribes the busbar. The current carrying system also includes an air vent defined by the at least one cooling feature and the casing, wherein the air vent is in flow communication with ambient air, and the cooling feature is configured to facilitate a flow of air from the ambient air through the air vent.
    Type: Grant

  • Patent number: 9303330
    Abstract: The present disclosure relates to methods for manufacturing porous mesh plates for use in ultrasonic mesh nebulizers, and the porous mesh plates manufactured by those methods. Cone-shaped dimples are first drilled in a substrate (e.g. a plate), but do not penetrate the bottom of the substrate. Next, the substrate (e.g. a plate) is subject to an electrochemical process to remove a layer of material from the surface of the substrate. Enough material is removed to allow the dimples to penetrate the substrate, thereby creating holes in the substrate. The size of the holes can be controlled by the conditions of the electrochemical process.
