Patent number: 9752434Abstract: In such fields as road milling, mining and trenching it is often desirable to engage and degrade tough materials such as asphalt, concrete and rock. To do so, degradation picks comprising hardened distal tips may be secured to an exterior of a movable support such as a rotatable drum or continuous chain so as to be repeatedly brought into contact with a material to be degraded. To secure such degradation picks to the movable support, a block comprising a body with a base surface rigidly attachable to a movable support is disclosed. A first receptacle with a first central axis may be disposed on an external surface of the body and formed to receive a first removable degradation pick. A second receptacle with a second central axis may also be disposed on the external surface and formed to receive a second removable degradation pick where the first and second central axes are nonparallel.Type: GrantFiled: July 24, 2015Date of Patent: September 5, 2017Assignee: NOVATEK IP, LLCInventors: David R.

Patent number: 9741460Abstract: A system and method of disposing nuclear waste and other hazardous waste includes means for, and the steps of, blending a waste stream, which includes either a radioactive waste or a hazardous waste (or both), with a liquid and, optionally, a solid material to produce a dense fluid and pumping the dense fluid into a tubing string of an injection boring. The dense fluid then exits a perforation in a casing of the injection boring and enters a fracture in a rock strata, where it continues to propagate downward until it reaches an immobilization point. The dense fluid may be a slurry formed by a metal and a cross-linked polymer gel or hydrated clay slurry. The metal can be one that has a melting temperature less than the temperature at the bottom of the injection boring. The solid material could also be other nuclear waste or a radionuclide.Type: GrantFiled: November 4, 2016Date of Patent: August 22, 2017Assignee: Grand Abyss, LLCInventors: Leonid Germanovich, Lawrence C.

Patent number: 9714488Abstract: The invention relates to a road milling machine, with a milling drum housing partially surrounding a milling drum, wherein the opening between the milling drum housing and the surface of the material to be milled can be closed off by a hold-down device. The distance between the axis of rotation and the hold-down device increases in the specified direction of rotation of the milling drum at least over a section of the gap between the milling drum and the hold-down device. The particular configuration of the hold-down device leads to an improvement in transport of the milled material to the transport arrangement. The gap width increasing in the direction of rotation of the milling drum improves material flow with a relatively small power requirement and relatively low wear of the milling drum.Type: GrantFiled: January 20, 2015Date of Patent: July 25, 2017Assignee: Wirtgen GmbHInventors: Dirk Franzmann, Christian Berning, Herbert Ley, Cyrus Barimani, Günter Hähn
