Patent number: 11460384Abstract: A pressure test apparatus is provided for performing a pressure test on a part. The method of pressure testing the includes attaching the part to the pressure test apparatus and moving down a top plate assembly of the pressure test apparatus, where the moving down of the top plate assembly engages a connection to a transducer for the pressure test and blocks a connection to an air supply to the pressure test apparatus. Furthermore, the method includes measuring a level of pressure in the part.Type: GrantFiled: November 25, 2019Date of Patent: October 4, 2022Assignee: International Business Machines CorporationInventors: Douglas Alexander Smalley, Mateusz Koziol, Oswald J. Mantilla, Leung M. Hung

Patent number: 10314219Abstract: A device comprises a rail configured to span and detachably couple to a housing. The device includes a plate that engages the housing and a mechanism securing the tool to the housing. The housing contains a printed circuit board configured with at least one row of slots, each slot configured with a retainer mechanism. A jaw assembly slides along the rail over more than one card positioned in the row of slots. The assembly includes a pair of inserts that perform either seating or extracting more than one card positioned in more than one slot. The device includes a lever for biasing the jaw assembly, where the inserts engage a selected one of more than one card positioned in more than one slot and the retainer mechanism for performing either simultaneously seating more than one card into or simultaneously extracting more than one card from more than slot.Type: GrantFiled: January 18, 2017Date of Patent: June 4, 2019Assignee: International Business Machines CorporationInventors: Karl O. Casserly, Mark L. Monroe, Leung M. Hung, Ronny R. Shipley, Tracy A. Tong, James Verzi
