A method of producing a drill bit, such as for drilling a well into an earth formation, includes forming a bit body having a plurality of blades. Each of the plurality of blades includes a forward facing face with respect to a direction of rotation of the bit. The forward facing face includes individual cutter pockets at least partially recessed into the forward facing face. The method also includes securing a cutting element at least partially within each of the individual cutter pockets. Each cutting element has an abrasion resistance. Each of the plurality of blades is formed of a blade material having an abrasion resistance that is less than the abrasion resistance of the cutting element.

Drill bit with continuously sharp edge cutting elements

A method of optimizing drill bit design and an optimized drill bit for drilling a well into an earth formation comprising a bit body; a number of blades spaced around the bit body, each blade having a curved outer edge and a forward face; a first row of cutter pockets recessed into the face along the outer edge of each blade; a second group of cutter pockets recessed into the face of each blade offset from the first row; and a plurality of cutting elements, each cutting element being brazed into a different one of the cutter pockets.

Earth-boring tools include wear-resistant materials disposed in at least one recess formed in an exterior surface of a body thereof. Exposed surfaces of the wear-resistant material are substantially level with exterior surfaces of the body adjacent the wear-resistant material. In some embodiments, recesses may be formed in formation-engaging surfaces of blades of earth-boring rotary tools, adjacent one or more inserts secured to bodies of earth-boring tools, or adjacent one or more cutting elements secured to bodies of earth-boring tools. Methods of forming earth-boring tools include filling one or more recesses formed in an exterior surface of a body with wear-resistant material and causing exposed surfaces of the wear-resistant material to be substantially level with the exterior surface of the body.

Methods for applying wear-resistant material to exterior surfaces of earth-boring tools and resulting structures

A drill bit having a bit body includes a blade face surface on at least one blade extending longitudinally and radially outward over a face of the bit body. The blade face surface of the at least one blade includes a contact zone and a sweep zone. The sweep zone rotationally trails the contact zone with respect to a direction of intended bit rotation about a longitudinal axis of the bit body provides reduce rubbing contact when engaging with a subterranean formation.

A method of constructing an earth-boring, diamond-impregnated drill bit has a first step of coating diamond grit with tungsten to create tungsten-coated diamond particles. These coated particles are then encapsulated in a layer of carbide powder held by an organic green binder material. The encapsulated granules are then mixed along with a matrix material and placed in a mold. The matrix material includes a matrix binder and abrasive particles. The mixture is heated in the mold at atmospheric pressure to cause the matrix binder to melt and infiltrate the encapsulated granules and abrasive particles.

An earth boring drill bit comprising cones, each cone having a land on its mid portion with at least two rows of compacts that are staggered with respect to adjacent compacts on another row. The compacts of these two rows may also have the same size. The compacts of these two inner rows are closer to each other than to any other compacts on the cone.

Educational model

An exercise device for simulating walking and stairclimbing and providing low impact aerobics for exercising the lower body. The exercise device includes a frame mounted on a base. The frame includes an upright standard mounted on a front of the base and angled rearwardly. A handle bar with handle bar grips is attached to a top of the standard. An upper end of a pair of hydraulic cylinders is attached to the standard. A lower end of the hydraulic cylinders is attached to a first and second independent step. A front pivot portion of the steps is mounted on a pivot shaft which is mounted on the standard. A pair of torsion springs is disposed around opposite ends of the pivot shaft. The torsion springs bias the steps upwardly at an angle above the horizontal. When a user of the exercise device steps on a rear step portion of the steps and downward pressure is applied on the first step, the cylinder telescopes downwardly and the torsion spring is flexed around the pivot staff. When downward pressure is applied on the second step and the pressure relieved from the first step, the second step moves downwardly as the first step returns to its upward position. By first applying pressure on one foot and lifting the other foot, a natural floating type simulation of climbing steps occurs when using the subject exercise device.
