Auger Fingers For Harvesting Assemblies, And Combines Used Therewith

US Patent:
2003004, Mar 6, 2003
Filed:
Aug 31, 2001
Appl. No.:
09/944645
Inventors:
Ronald Sheedy - Eldridge IA, US
Fredrick Ward - Moline IL, US
Keith Dennehy - Winona MN, US
Kyle Tingle - Colona IL, US
Assignee:
Deere & Company - Moline IL
International Classification:
A01D057/03
US Classification:
056/364000
Abstract:
Intake fingers and finger assemblies for use with intake portions of harvesting assemblies, on harvesting machines such as combines, haybines, bailers, corn pickers, and the like. The fingers and finger assemblies cooperate with crop-gathering augers, and crankshafts inside the augers, in feeding cut crop material toward discharge portions of such harvesting assemblies. The fingers extend and retract through apertures in the auger cylinder according to an eccentric mounting of the finger crankshaft inside the auger cylinder. A respective finger comprises a reinforced polyester or polyurethane shaft, and a polyurethane sleeve overlying a crop-engaging end portion of the finger, such as along 50% to 80% of the length of the shaft. In preferred embodiments, the shaft is reinforced with fiberglass or other fiber, the composition of the sleeve comprises polyester-based thermoplastic polyurethane, and the sleeve has a hardness of about Shore D-45 to about Shore D-70.

Superconducting Electrical Machine With Compliant Winding Support

US Patent:
2016020, Jul 14, 2016
Filed:
Jan 9, 2015
Appl. No.:
14/593928
Inventors:
Darrell Morrison - Eagle Lake MN, US
Keith T. Dennehy - Winona MN, US
International Classification:
H02K 3/30
Abstract:
A superconducting electrical machine includes a stator and a rotor configured to rotate in a cavity defined by the stator. The rotor and the stator each include superconducting windings. The rotor and the stator also each include a composite configured to compensate for a volume change of various components of the rotor and stator during a change in temperature from a first temperature to a second temperature.
