Patent number: 11590891Abstract: A control system for a machine includes a machine, a plurality of proximity sensors coupled to the machine, and a controller in communication with the plurality of proximity sensors. The controller is configured to activate and monitor proximity information from the proximity sensors during a containerization mode and indicate an alert if the proximity information is below a threshold distance.Type: GrantFiled: January 16, 2020Date of Patent: February 28, 2023Assignee: Caterpillar Paving Products Inc.Inventors: Terry R. Stoe, Andrew J. Steinbach

Patent number: 6613106Abstract: Membrane electrode assemblies are described that include an ion conductive membrane a catalyst adjacent to the major surfaces of the ion conductive membrane and a porous particle filled polymer membrane adjacent to the ion conductive membrane. The catalyst can be disposed on the major surfaces of the ion conductive membrane. Preferably, the catalyst is disposed in nanostructures. The polymer film serving as the electrode backing layer preferably is processed by heating the particle loaded porous film to a temperature within about 20 degrees of the melting point of the polymer to decrease the Gurley value and the electrical resistivity. The MEAs can be produced in a continuous roll process. The MEAs can be used to produce fuel cells, electrolyzers and electrochemical reactors.Type: GrantFiled: November 13, 2000Date of Patent: September 2, 2003Assignee: 3M Innovative Properties CompanyInventors: Mark K. Debe, James M. Larson, William V. Balsimo, Andrew J. Steinbach, Raymond J. Ziegler

Patent number: 6425993Abstract: A method is provided for making a membrane electrode that employs a composite membrane, which include both a porous membrane and an ion conducting electrolyte, by partially filling a porous membrane with an ion conducting electrolyte to form a partially filled membrane and then compressing the partially filled membrane with electrode particles so as to remove void volume from the partially filled membrane and embed the electrode particles in the partially filled membrane. The membrane electrode of this invention is suitable for use in electrochemical devices, including proton exchange membrane fuel cells, electrolyzers, chlor-alkali separation membranes, and the like.Type: GrantFiled: March 23, 2000Date of Patent: July 30, 2002Assignee: 3M Innovative Properties CompanyInventors: Mark K.
