Patent number: 10613450Abstract: The present disclosure relates generally to a method to make a chemically prepared toner that employs a crash cooling process. In particular, the crash cooling process involves the addition of a toner slurry having a temperature between 70° C. and 90° C. to an equivalent amount of cold water having a temperature between 5° C. and 20° C. Polyester and styrene acrylic toners as well as polyester core shell toners having a borax coupling agent between the toner core and toner shell made from this cooling process results in an improvement to the amount of toner waste, thereby achieving a higher toner usage efficiency for an electrophotographic printing system.Type: GrantFiled: April 3, 2019Date of Patent: April 7, 2020Assignee: LEXMARK INTERNATIONAL, INC.Inventors: Kasturi Rangan Srinivasan, Rahel Bekru Bogale, Trent Duane Peter, Brian David Munson

Patent number: 7648450Abstract: An apparatus for physical fitness physical strength, agility and endurance training. A controllable pressurized flow of fluid is first received via a hose to a source of the pressurized fluid. In response to this flow of fluid, a force is generated along at least one of a plurality of selected directions using one or more apertures or nozzles. The force is then transferred to a user of the apparatus so as to supply physical resistance training to the user. The apparatus further includes a user engaging mechanism that is connected to the propulsion system, and is configured to transmit exercise forces to an associated user. The apparatus further includes controls for controlling the magnitude and direction of the reaction force vector applied to the user engaging mechanism. Various embodiments of user engaging members, including blocking dummies, handles, gloves, helmets, shoes, straps or balls, may be attached to the propulsion system.Type: GrantFiled: March 21, 2007Date of Patent: January 19, 2010Assignee: FOI Group, LLCInventor: David Munson, Jr.

Patent number: 7547269Abstract: An improved method and apparatus for physical strength, agility and endurance training uses fluid jet reaction forces to train and strengthen muscles. The device for physical training includes a source of pressurized fluid connectable through a hose to a propulsion system and one or more apertures or nozzles for forming one or more jets of fluid that are discharged from the propulsion system such that a nozzle reaction force, acting in a direction opposite the direction of the jet stream, is exerted on the jet propulsion system. Fluid can also be delivered through a curved tube or passage in the propulsion system such that a stream of fluid that is discharged from the propulsion system is not traveling in the same direction as it was before it was discharged such that the change in direction of the fluid causes a change in the momentum of the fluid for exerting an additional reaction force on the propulsion system.Type: GrantFiled: December 16, 2003Date of Patent: June 16, 2009Assignee: FOI Group, LLCInventor: David Munson, Jr.
