Patent number: 12138350Abstract: The present invention relates to a method of producing a direct compression tablet composition comprising the step of processing ibuprofen, a hydrophilic polymer, and an inorganic excipient by an extrusion process to produce an extruded composition in which the ibuprofen forms a solid dispersion/solution within the hydrophilic polymer. The invention is particularly useful in preparing oral dissolvable tablets. Also provided are composition comprising an inorganic excipient and ibuprofen within a hydrophilic polymer.Type: GrantFiled: February 9, 2016Date of Patent: November 12, 2024Assignees: Cubic Pharmaceuticals Ltd., Delta Pharmaceuticals Ltd.Inventors: Dennis Douroumis, Mohammed Maniruzzaman, Saumil Kiritkumar Bhatt, Anwar Ali, Arun Jangra

Publication number: 20240301523Abstract: Disclosed herein is an example track pad having a ground-contacting portion for use in a track-based machine to propel and support the machine across a supporting surface. The track pad may be a track pad that forms a link of a chain forming the track for the track-based machine. The track pad includes a cast body formed of a first alloy steel having a first strength and toughness. The track pad includes a roll path that contacts a roller of the track-based machine. The roll path is hardened through an induction hardening process to achieve a hardness level at a depth of 32 millimeters or more from the surface of the roll path. The roll path is shaped and positioned to contact rollers of the track drive assembly and thereby reduce wear and fatigue on the track pad as a result of contact and force transferred through the roller.Type: ApplicationFiled: March 10, 2023Publication date: September 12, 2024Applicant: Caterpillar Inc.Inventors: Scott Howard Magner, Mircea Dumitru, Brian Konrad Loeffler, Mohammed Maniruzzaman, Yongqiang Li, Simon Jiang
