20130279948 | MULTI-TONER DISCHARGED AREA DEVELOPMENT METHOD - Printing methods are provided. A surface charge is provided on the primary imaging member and the surface charge is partially discharged in areas in which a first toner is to develop. The charge pattern is formed with a first area having a surface potential that is at least 30 percent less than a surface potential of an adjacent second area that creates an inter-area field between the first area and second area that extends into a portion of the first area that is proximate to the second area. A first development field is applied and a first toner is partially developed in the first area based upon the influence of the inter-area and first development fields. The charge pattern and the first toner are further developed with a different second toner. The surface charge on the primary imaging member, first toner and second toner have the same polarity. | 10-24-2013 |

20140150284 | ACOUSTIC DRYING SYSTEM WITH INTERSPERSED EXHAUST CHANNELS - An acoustic air impingement drying system is provided for drying a material. An inlet chamber receives air from an airflow source provides air at a supply flow rate. A plurality of acoustic resonant chambers are provided, each having an inlet slot that receives air from the inlet chamber and an outlet slot that directs air onto the material, wherein the acoustic resonant chambers impart acoustic energy to the transiting air, the outlet slots being oriented at an oblique angle relative to the width dimension of the pneumatic transducer unit. A plurality of exhaust air channels interspersed between the outlet slots remove the air directed onto the material by the acoustic resonant chambers. A blower pulls air through the exhaust air channels at an exhaust flow rate. | 06-05-2014 |
