Patent number: 8992379Abstract: A hybrid drivetrain for a motor vehicle includes an automated mechanical transmission (AMT) having an output shaft. The drivetrain includes an alternative energy source including a motor and an energy storage unit and two torque transfer arrangements. The first transfer arrangement is separate from engageable gear sets of the AMT for transferring torque from the output shaft to a motor when the energy storage unit is being charged and for transferring torque from the motor to the output shaft when the energy storage unit is being discharged. Additionally, an alternative energy source clutch for selectively coupling the first torque transfer arrangement to the output shaft is included. The second torque transfer arrangement is for transferring torque from the output shaft to a driven axle of the motor vehicle. At least one of the first and second torque transfer arrangements has different first and second torque transfer ratios.Type: GrantFiled: October 27, 2011Date of Patent: March 31, 2015Assignee: Eaton CorporationInventors: Robert L. Isaacs, Benjamin M. Hoxie

Patent number: 8365637Abstract: An output transfer group, or drop box, can include a housing and a gear transfer train, rotatably supported within the housing, that includes an input gear adapted for enmeshing engagement with a transmission output shaft and a gear transfer output shaft that is rotatable upon rotation of the input gear. A coupler can be provided that includes a hub rotatively coupled with the gear transfer output shaft, a bearing carrier, a coupler output shaft rotatively coupled to the bearing carrier, and a coupling mechanism rotatively coupled to the bearing carrier. The coupling mechanism can be movable between an engaged position, wherein the coupling mechanism is rotatively coupled to the hub, and a disengaged position, wherein the coupling mechanism is disengaged from the hub. A solenoid can be arranged with the coupling mechanism to selectively move the coupling mechanism from the disengaged position to the engaged position.Type: GrantFiled: October 23, 2007Date of Patent: February 5, 2013Assignee: Caterpillar Inc.Inventors: Robert A. Herold, Nuwan Janaka Gallege, Dean A. Worrell, Robert L. Isaacs, Samuel Shropshire

Patent number: 5576364Abstract: The present invention is directed toward a fibrous web having improved strength characteristics which, in the presence of water, rapidly disintegrates when subjected to standardized agitation testing. The web includes a plurality of fibers joined together by a binder. The binder makes up from about 0.20 to about 15 percent of the dry weight of the web. The binder is formed from a blend of from about 10 to about 40 weight percent of a water dispersible polymer; from about 10 to about 40 weight percent of an elastomeric latex emulsion; from about 20 to about 40 weight percent of a xerogellant; and from about 5 to about 20 weight percent of a plasticizing agent. The fibrous web is useful in the formation of disposable diapers and feminine care products which may be flushed down the toilet.Type: GrantFiled: May 22, 1995Date of Patent: November 19, 1996Assignee: Kimberly-Clark CorporationInventors: Robert L.

Patent number: 5470424Abstract: Disclosed are a number of processes for forming a liquid-impermeable sheet having a fibrous cloth-like surface. In one embodiment the process includes the steps of: (1) forming a sheet having first and second fibrous surfaces; and subjecting the sheet to pressure and a z-gradient temperature differential sufficient to melt the fibers of the first surface and form the melt into a liquid impermeable skin without significantly altering the fibers of the second surface.Type: GrantFiled: November 30, 1993Date of Patent: November 28, 1995Assignee: Kimberly-Clark CorporationInventors: Robert L. Isaac, Bernard Cohen, Lee K. Jameson

The binder is formed from a blend of from about 10 to about 40 weight percent of a water dispersible, high molecular weight amorphous polyester having one or more ionic substituents attached thereto; from about 10 to about 40 weight percent of an elastomeric latex emulsion; from about 20 to about 40 weight percent of a xerogellant; and from about 5 to about 20 weight percent of a plasticizing agent. The fibrous web is useful in the formation of disposable diapers and feminine care products which may be flushed down the toilet.Type: GrantFiled: August 17, 1993Date of Patent: November 14, 1995Assignee: Kimberly-Clark CorporationInventors: Robert L.
