  • Sublingual compositions including epinephrine nanoparticles
    Patent number: 10251849
    Abstract: The invention provides compositions including epinephrine nanoparticles and methods for therapeutic use of the compositions for the treatment of conditions responsive to epinephrine such as a cardiac event or an allergic reaction, particularly anaphylaxis. The epinephrine nanoparticles can be incorporated into orally-disintegrating and fast-disintegrating tablet pharmaceutical formulations and can significantly increase the sublingual bioavailability of epinephrine, and thereby reduce the epinephrine dose required. Additionally, the invention provides methods for fabrication of stabilized epinephrine nanoparticles for use in the described compositions.

  • CLEANING DENTAL MIRRORS
    Publication number: 20190090731
    Abstract: A cleaning tool is attachable to a dental air-water syringe tip. The tool has a frame which supports a mirrored surface. tool grip is attached to the frame, and includes a resilient body and a channel extending through the body. The channel is sized smaller than a diameter of the syringe tip. A support arm connects the frame and the tool grip, and the frame and the tool grip are each connected to the support arm at a predetermined angle which causes there to be a predetermined angle between a longitudinal axis of the channel, and thus the output of the tool tip, and the mirror surface.

  • Surface planarization system and method
    Patent number: 10226852
    Abstract: A surface planarization system is presented. The system comprises an external energy source for generating a localized energy distribution within a processing region, and a control unit for operating the external energy source to create, by the localized energy distribution, a predetermined temperature pattern within the processing region such that different locations of the processing region are subjected to different temperatures. This provides that when a sample (e.g. semiconductor wafer) during its interaction with an etching material composition is located in the processing region, the temperature pattern at different locations of the sample's surface creates different material removal rates by the etching material composition (different etch rates).

    Patent number: 10221266
    Abstract: A method is provided to control the short chain branching (SCB) distribution of an ethylene-butene (EB) polyethylene resin that is prepared in a gas phase polymerization process using a specific type of magnesium-titanium Ziegler Natta catalyst. The method allows the level of short chain branching to be increased in the low molecular weight fraction of the resin by increasing the polymerization residence time. The polymers that are produced in accordance with this invention may be useful for the preparation of cast films and blown films, especially for stretch film applications.
