Publication number: 20250087772Abstract: A cell-testing apparatus for testing one or more cells includes a cell-test enclosure that includes at least one internal vent. The cell-testing apparatus also includes an external housing that contains the cell-test enclosure and that includes at least one exhaust vent that vents to outside the external housing. During testing, the cell-test enclosure is located within the external housing so as to define at least one explosion-gas pathway from the at least one internal vent to the at least one exhaust vent. In some embodiments, the venting axis of the internal vent(s) is perpendicular to the venting axis of the exhaust vent(s). In some embodiments, the vents each comprise one or more fenestrated plates. In some embodiments, the cell-test enclosure is a drawer-type enclosure including a cabinet and a drawer that is designed and configured to receive a battery cell for testing.Type: ApplicationFiled: August 19, 2024Publication date: March 13, 2025Inventors: Yong Duan, LuYong Shen, Biao Xu

Publication number: 20240334962Abstract: A tobacco-free oral pouch product providing immediate and long lasting flavor release comprises a pouch wrapper and tobacco-free flavor beads contained within the pouch wrapper. The flavor beads comprise at least one of microcrystalline cellulose, pectin and sodium alginate, at least one polymer having a higher solubility in saliva than microcrystalline cellulose, pectin and/or sodium alginate, and at least one flavorant. The pectin and sodium alginate are cross-linked. The tobacco-free flavor beads provide immediate release of the flavorant upon placement of a pouch product in a user's mouth and long lasting release of the flavorant for about 15 minutes to about 80 minutes.

Publication number: 20170189881Abstract: The invention teaches a method of efficiently dewatering a microcapsule slurry to form a water re-suspendable filter cake of microcapsules. The process comprises providing an aqueous slurry of microcapsules dispersed in an aqueous solution; adding an agglomeration agent and dispersing the agglomeration agent into the aqueous slurry; adjusting the pH to a pH level sufficient to agglomerate the dispersed microcapsules; and filtering the aqueous slurry of microcapsules by gravity, vacuum or pressure filtration to thereby form a filter cake of dewatered microcapsules. The agglomeration agent is sodium polyphosphate, sodium tetrapolyphosphate, sodium hexametaphosphate, and/or sodium tripolyphosphate; or with anionic microcapsules or coatings even alkaline earth metal salts such as magnesium chloride, calcium chloride or barium chloride, or even aluminum salt such as aluminum chloride.Type: ApplicationFiled: February 20, 2017Publication date: July 6, 2017Applicant: Encapsys, LLCInventor: Biao Duan
