Abstract: A material processing tool assembly includes a tool for material processing having a base section and a processing section extending from the base section; and a tool mounting block mountable on an outer surface of a support base. The mounting block has a base surface and a tool mounting surface intersecting the base surface. The base surface has a protuberance extending away therefrom and spaced apart from the tool mounting surface to define a tool receiving gap between the protuberance and the tool mounting surface. The base section of the tool is snugly received in the tool receiving gap between the tool mounting surface and the protuberance in abutment with the tool mounting surface, the processing section of the tool extending past the protuberance. A displaceable material processing head and method of mounting a material processing tool to a mounting block secured to a displaceable head are also discussed.

Abstract: A system and method may model physical geological structures. Seismic and geologic data may be accepted. A three-dimensional (3D) transformation may be generated between a 3D present day model having points representing present locations of the physical geological structures and a 3D past depositional model having points representing locations where the physical geological structures were originally deposited. An indication may be accepted to locally change the 3D transformation for a subset of sampling points in a first model of the models. The 3D transformation may be locally changed to fit the updated subset of sampling points. A locally altered or updated version of the first model and, e.g., second model, may be displayed where local changes to the first model are defined by the locally changed 3D transformation. The transformation may also be used to extract geobodies in the past depositional model.

Abstract: A method, apparatus and system for modeling a fault surface in a subsurface region. A direction may be determined in which a first portion of the subsurface region being on one side of the fault surface has moved relative to a second portion of the subsurface region being on the other side of the fault surface. A model of the fault surface may be generated having substantially no protrusions in the determined direction. A visualization of the model of the generated fault surface may be displayed.

Abstract: A system and method for modeling a subsurface structure. Data representing a configuration of faults, horizons, and/or unconformities may be transformed to a depositional model comprising cells representing an estimated configuration of subsurface structure at a depositional time period when the subsurface structure was formed. Groups of cells in the depositional model may be divided into sub-meshes using iso-surfaces, where one set of iso-surfaces may represent the horizons at the depositional time period. The sub-meshes may be divided into one or more parts using the transformed geological data representing an estimated depositional configuration of the faults. For each group of cells in each sub-mesh part, the group of cells in the sub-mesh part may be represented by a single polyhedron. The polyhedrons may be transformed to generate a current model to represent the current configuration of the faults and horizons using transformed polyhedrons.

Abstract: A cutting tooth having a blade-like cutting section and a mounting section extending down from the bottom of the cutting section. The mounting section is narrower and shorter than the cutting section, and generally centered with respect to the cutting section. The mounting section has laterally extending flanges spaced from the cutting section. At least a quarter of the cutting section extends past the front of the mounting section and terminating in a cutting edge. The cutting tooth is adapted to be mounted in a mounting block to form a cutting assembly. The mounting block has a slot extending into the block from the front face, the slot open in the top surface of the block. The mounting section of the tooth slides into the slot in the block to locate the cutting section on the top of the block with the cutting section projecting forwardly of the block. The flanges on the tooth hold the tooth in place in the block against centrifugal forces.

Abstract: A wear liner for use with a brush cutter, the cutter having a cylindrical, rotatable, cutting drum carrying cutting teeth and a cover at least partially covering the drum to limit dispersal of cut material. The liner comprises a sheet of material which can be shaped to fit against the inner surface of the cover. The liner has holes on its sides for use in detachably connecting the liner with fastening means to the cover against the cover's inner surface. The liner has protective means mounted on its inner surface adjacent each hole to protect part of the fastening means located adjacent the inner surface of the liner, when the liner is mounted to the cover and the fastening means extend through the opening, from wear by material thrown by the cutter during its operation. The invention is also directed toward a brush cutter incorporating the liner.

Abstract: A rotary cutter for a brush cutter. The cutter has a rotatable cylindrical drum with a plurality of flat, annular, collars mounted on the drum. The collars are fastened to the drum by their inner circular edge, are equally spaced apart on the drum, and extend transverse to the rotational axis of the drum. A cutting tooth mounting block is mounted between each adjacent pair of collars, the block located at the outer edge of the collars and spaced above the surface of the drum to provide a gap for passing chips and residue. The mounting block carries a detachable cutting tooth, the tooth extending forwardly generally tangentially from the block and terminating in a cutting edge above the collars.
