  • Patent number: 11857520
    Abstract: A nasal spray formulation and a method of using a locally acting sodium channel blocker to treat pain is disclosed, wherein the nasal spray formulation comprises from about 5% to about 30% w/v of a locally active sodium channel blocker, from about 0.25% to about 5% w/v of a buffering agent, and from about 5 to about 99% w/v of a pharmaceutically acceptable carrier for nasal administration. The nasal spray formulation is preferably contained in a mechanical multi-dose pump which sprays a unit dose of the nasal spray formulation with a wide plume and small droplet size, such that the unit dose is administered by actuating the mechanical multi-dose spray pump device and spraying a volume of the nasal spray formulation into each nostril of a human subject. Preferably, the nasal spray formulation does not include a preservative.

  • Publication number: 20230194587
    Abstract: A method for determining a capacitance value of a capacitor is provided. The method includes receiving a current signal flowing through the capacitor and receiving a voltage signal applied across the capacitor. The received voltage signal and the received current signal are filtered with a low pass filter. The filtered voltage signal and the filtered current signal are then discretized. The discretized voltage signal and the discretized current signal are transformed into a frequency domain. The capacitance value of the capacitor is determined from the transformed voltage signal and the transformed current signal.

  • Publication number: 20210060509
    Abstract: A reforming reactor and process of using same in which a flow distributor distributes the process gas circumferentially to the reactive zone. Feed is injected into the reactor into a non-reactive zone. The non-reactive zone has two portions, a first portion receiving the feed, and a second portion receiving a purge gas. The purge gas will flow from the second portion to the first portion to prevent flow of the feed from the first portion to the second portion. The combined gas may be passed to a reaction zone for catalytic reforming. The first portion and the second portion may be separated by a flow distributor having two horizontal portions connected to opposite ends of a vertical portion.
