Patent number: 6715490Abstract: A respirator 15 has a harness 10 that allows the respirator body 20 to be conveniently disposed beneath a wearer's chin when not in use. The harness 10 includes a substantially flat, flexible strap 14 and an element 12 that contains a curved elongated slot 16. The substantially flat, flexible strap 14 is threaded through the curved elongated slot 16. The curved configuration of the slot 16 causes the flat flexible strap 14 to be deformed to assume the curved configuration of the slot. This deformation of the strap 14 allows the strap 14 to frictionally engage element 12, and the frictional engagement allows the respirator body 20 to be incrementally withdrawn from the wearer's face so that it can be temporarily stored beneath the wearer's chin, and allows the respirator body 20 to be conveniently repositioned over the nose and mouth of the wearer by simply pulling on free ends 34 of each strap 14 and joining a buckle 32 behind the wearer's neck.Type: GrantFiled: March 18, 2003Date of Patent: April 6, 2004Assignee: 3M Innovative Properties CompanyInventor: David C.

Patent number: 6494021Abstract: A method and apparatus for transferring a wet object, such as a contact lens, from a first station to a second station includes a probe having a barrel with a passage for communication with a vacuum source and a pressurized gas source, a nozzle at the end of the passage, and a hood around the nozzle in communication with a vacuum source. The barrel is moved in a first direction to place the nozzle adjacent the object in the first station and the vacuum from the nozzle attaches the object to the nozzle. Moving the barrel in a second direction removes the nozzle with the object attached from the first station. The probe is moved to the second station with the object attached. The barrel is moved in the first direction to place the object at the second station, the vacuum is removed from the nozzle and pressurized gas is applied through the barrel passage to remove the object from the nozzle and deposit it at the second station and, at the same time, blow off matter from the object.Type: GrantFiled: February 18, 1999Date of Patent: December 17, 2002Assignee: Johnson & Johnson Vision Care, Inc.Inventors: Mark E. Schlagel, David C. Byram, Darren S. Keene
