Publication number: 20230024887Abstract: A concave section for a harvester includes a concave body having an upstream side, a downstream side, a leading end and a trailing end. The concave body defines an arcuate crop engagement face facing radially inwardly. A plurality of crop passage openings are defined through the arcuate crop engagement face. A cover is configured to at least partially cover at least some of the crop passage openings. The cover is carried by the concave body and is movable thereon between at least two different positions to adjust a degree of openness of at least some of the crop passage openings.Type: ApplicationFiled: September 28, 2022Publication date: January 26, 2023Applicant: Kondex CorporationInventors: Andrew J. Theisen, Keith A. Johnson, Neal J. Stoffel, Joseph W. Schaffer

Publication number: 20200325584Abstract: A boring bit or other component for horizontal directional drilling is provided which includes a hard faced layer that is preferably made by a laser cladding bead. A subsequent or post heat treatment is applied to modify the heat affected zone (HAZ) to eliminate or reduce the hard brittle regions and/or softer regions in the base iron or steel material of the HAZ. Further, the hard faced layer may be applied in combination with carbide insert teeth that are embedded within the steel base of the boring bit body, such as by press fitting.Type: ApplicationFiled: March 28, 2020Publication date: October 15, 2020Applicant: Kondex CorporationInventors: Keith A. Johnson, Andrew J. Theisen, Mark More, Casey Placek

Publication number: 20200224499Abstract: A boring bit such as for horizontal directional drilling is provided which includes a hard faced layer that is preferably made by a laser cladding bead. The laser clad bead may be applied in some regions to a greater extent and in other regions to a lighter extent and with thicker coverage or longer regions of application in different regions of the boring bit. Additionally, circumferential segments of the hard faced layer bead may be applied to impart a spiral path on the outer periphery of the boring bit which may be overlapped upon more general hard faced layer application. Further, the hard faced layer may be applied in substantially complete coverage over carbide insert teeth that are embedded within the steel base of the boring bit body.Type: ApplicationFiled: March 31, 2020Publication date: July 16, 2020Applicant: Kondex CorporationInventors: Keith A. Johnson, Andrew J. Theisen, Mark More, Casey Placek
