David Kalman Biegelsen, Warren Bruce Jackson, Lars Erik Swartz: Modular air jet array with coanda exhausting for module decoupling. Xerox Corporation, Oliff & Berridge, September 14, 1999: US05951006 (13 worldwide citation)

A decoupling mechanism is provided for passively or actively decoupling an exhaust from a modular air transport system by diverting an amount of air exiting a channel in a first module in a direction other than the process direction through use of the Coanda effect. This decouples the amount of air ...

Lars Erik Swartz, David Kalman Biegelsen: Air bearing mechanism for flattening paper in a printing machine. Xerox Corporation, Perman & Green, August 27, 2002: US06442369 (7 worldwide citation)

A device for enhancing the transport of sheets in a printing machine is constructed upstream of the image transfer station to flatten the paper against the transport belt or drum on which it is riding. An air cushion is generated by expelling pressurized air through an array of holes to provide an a ...
