20120210691 | Bell Knife for Rotary Mower - A crop harvesting header has a cutter bed to cut crop material as the harvester advances through a field. The cutter bed includes a plurality of rotatable cutters having knives extending from opposing ends of the cutters. Each cutter has a generally elliptical knife carrier, and a pair of knives at opposites ends of the carrier, wherein a portion of each knife extends beyond the end of the carrier to expose a cutting surface to sever the standing crop. Each knife is shaped such that its width dimension at a proximal end where mounted on the knife carrier is narrower than its width dimension at a distal end extending away from the knife carrier. | 08-23-2012 |
20120210692 | Fixed Rotary Knife - A crop harvesting header has a cutter bed to cut crop material as the harvester advances through a field. The cutter bed includes a plurality of rotatable cutters having knives extending from opposing ends of the cutters. Each cutter is ninety degrees out of phase with respect to its adjacent cutters such that the circular paths of travel of the knives of adjacent cutters overlap one another, and adjacent cutters rotate in opposite directions. Each cutter has a generally elliptical knife carrier, and a pair of knives at opposites ends of the carrier, wherein a portion of each knife extends beyond the end of the carrier to expose a cutting surface to sever the standing crop. The cutter also includes an attachment device connecting each knife to the knife carrier, and a fixed stop restricting rotational movement of the knife with respect to the carrier about the attachment device. | 08-23-2012 |

20160069154 | PRESSURE RELEASE ASSEMBLY FOR CASING OF DRILLING RIG - An apparatus is for a drill rig platform configured to be operative with a casing system having a check valve fixedly positioned in a casing joint. The apparatus includes a casing pressure relief assembly fixedly positionable relative to the check valve positioned in the casing system. The casing pressure relief assembly is configured to actuate the check valve in such a way that the check valve actuatably releases internal pressure from the casing system. In this manner, the internal fluid pressure of the pressurized fluid trapped in the casing system is released once the casing pressure relief assembly actuates the check valve. | 03-10-2016 |
