Drive Roller For Belt In An Electrophotographic Image Forming Apparatus

US Patent:
6965748, Nov 15, 2005
Filed:
Mar 26, 2004
Appl. No.:
10/811188
Inventors:
Kerry Leland Embry - Midway KY, US
Richard Seman - Delmont PA, US
Edward Lynn Triplett - Lexington KY, US
Assignee:
Lexmark International, Inc. - Lexington KY
International Classification:
G03G015/00
US Classification:
399302, 399167
Abstract:
An electrophotographic image forming apparatus comprises a drive roller having a textured finish with a plurality of microscopic protrusions and a plurality of microscopic depressions; the drive roller comprising a shaft and a surface coating on the shaft; a flexible belt having a first hardness driven by the drive roller, the belt moving at least one of a toner image or a recording media having a toner image thereon; with the surface coating comprising a base compound and plurality of grit particles having a second hardness which is higher than the first hardness. The grit coating may advantageously have a thickness of not more than about 50 microns. The grit particles may comprise one or more ceramics, or one or more polymer compounds, or other materials. The drive roller advantageously has a coefficient of static friction of at least 0. 5 with the belt.

Modular Pressure Support System

US Patent:
2007016, Jul 26, 2007
Filed:
Sep 23, 2005
Appl. No.:
11/234351
Inventors:
Jeffrey Kepler - Export PA, US
Michael Mort - Somerset PA, US
Richard Seman - Delmont PA, US
Mark DiMatteo - Irwin PA, US
Christopher McCracken - Monroeville PA, US
James Vreeland - Greensburg PA, US
Steven Radney - Pittsburgh PA, US
Michael Bobeck - Sarver PA, US
Allan Cameron - Natick MA, US
David Chastain - Boston MA, US
Patrick McDermott - Oxford MA, US
William Palm - Newtonville MA, US
Roy Thompson - Dorchester MA, US
International Classification:
A61M 11/00
US Classification:
128200230, 128200140, 128200210
Abstract:
A pressure support system that comprises a patient circuit, a docking assembly, and a tank. The patient circuit delivers a pressurized flow of breathable gas to a patient. The docking assembly has an inlet and an outlet that is adapted to receive the pressurized flow of breathable gas, and is also adapted to be connected with the patient circuit. The tank is constructed and arranged to be removably connected with the docking assembly, and enables the pressurized flow of breathable gas to pass therethrough. The tank is also adapted to contain a liquid such that a humidity level of the pressurized flow of breathable gas is elevated as the pressurized flow of breathable gas passes therethrough.

Continuous Fluid Delivery System

US Patent:
2011000, Jan 6, 2011
Filed:
Dec 10, 2008
Appl. No.:
12/745849
Inventors:
Christopher D. Capone - Pittsburgh PA, US
James R. Neill - Oakdale PA, US
Richard A. Seman - Delmont PA, US
Jason L. Bazala - Irwin PA, US
Roger V. Delonga - Pittsburgh PA, US
Assignee:
MEDRAD, INC. - Indianola PA
International Classification:
F04B 19/00
US Classification:
417486
Abstract:
The continuous fluid delivery systems includes a fluid pumping device comprising a pump housing comprising a base member with a plurality of inlet ports and at least one outlet port and at least two pairs of opposing pistons movably associated with the housing. Each pair of opposing pistons at least in part defines a respective pumping chamber of the fluid pumping device. The pistons in each pair of opposing pistons may be independently controlled such that any one of the plurality of inlet ports or the at least one outlet port is independently selectable to be in fluid communication with one of the respective pumping chambers. A drive system may be interfaced with the respective pistons to at least reciprocally operate the pistons relative to the base member. The pump housing and the at least two pairs of opposing pistons may comprise a disposable unit.
