Publication number: 20120259297Abstract: An apparatus for cleansing and applying therapy or prophylaxis to wounds, in which irrigant fluid containing a physiologically active material from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. A biodegradable scaffold underlies the dressing on the wound bed to promote tissue growth. The cleansing means (which may be a single-phase, e.g. micro-filtration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing, an assembly comprising the dressing and scaffold, and a method of treatment using the apparatus.Type: ApplicationFiled: February 13, 2012Publication date: October 11, 2012Applicant: SMITH & NEPHEW PLCInventors: Patrick Lewis Blott, Bryan Greener, Edward Yerbury Hartwell, Tina Michelle Walker, Julian Lee-Webb, Derek Nicolini, Robin Paul Martin

Patent number: 8235151Abstract: A return to neutral control mechanism for a zero turning radius mower is disclosed. The return to neutral control mechanism includes a pair of control levers pivotable between forward, neutral and reverse positions. A brake pedal is moveable between a disengaged position to an engaged position. In response to engagement of the brake pedal, a control pivot attached to each control lever moves each control lever to the neutral position. The return to neutral control mechanism may include a cam that rotates in response to engagement of the brake pedal, and a control pivot that follows the cam during engagement of the brake pedal.Type: GrantFiled: August 14, 2007Date of Patent: August 7, 2012Assignee: Deere & CompanyInventors: Dimitri Nunez, Franklin Patrick Lewis, Damon C.
