A marking stylus for use in automated marking systems with one of the following superabrasive components as the scribing tip: polycrystalline diamond or polycrystalline cubic boron nitride. The superabrasive may have one or more chamfers, as well as a sharp, rounded, or blunt tip. The superabrasive is preferably attached to the body of the stylus by one of the following methods: brazing, press fit, shrunk fit, clamped, casted, injection molded, or a high pressure high temperature cycle.

Marking stylus for automated marking systems

A vacuum cup assembly that generates a local vacuum using a prime mover that may be an electrical motor or a solenoid. The vacuum cup may have one or more ports to remove and vent air between the cup and the atmosphere. The prime mover drives a piston or a flexible membrane, which may be a diaphragm, through one or more reciprocating cycles to generate the local vacuum. The vacuum cup assembly may be used to form a temporary attachment to a work piece, the act on the work piece, such as by moving the work piece, and then release the work piece from the vacuum cup assembly. The vacuum cup assembly disclosed herein is self-contained inasmuch as the assembly may have a power source, such as a battery, located on a housing. This makes its operation quiet and effective.

Vacuum cup assembly

A cutting element for an earth-boring drilling tool and its method of making are provided. The cutting element may include a substrate, a superhard layer, and a sensing element. The superhard layer may be bonded to the substrate along an interface. The superhard layer may have a working surface opposite the interface and an outer peripheral surface. The outer peripheral surface may extend between the working surface and the interface. The sensing element may comprise at least a part of the superhard layer.

Cutter tool insert having sensing device

A polycrystalline diamond compact (PDC) is fabricated using a process of delayed diffusion (i.e., post-sintering) of a diffusion species (i.e., a metalloid) introduced from the back side of a carbide further away from the diamond grit or from the flank side of the carbide, as opposed to the side of the carbide adjacent to the diamond grit. The process of fabricating the PDC includes depositing, in a metal container, a synthetic diamond grit, a carbide, and a diffusion species, then applying a high pressure and high temperature (HPHT) to the contents of the metal container wherein (1) the carbide diffuses across the diamond grit, and (2) the diffusion species diffuses across the carbide followed by the diamond grit, thus providing a protective coating to the PDC.

Delayed diffusion of novel species from the back side of carbide

A system and a method of testing a superabrasive cutter are disclosed. The system of testing a superabrasive cutter may comprise a spinning wheel holding the superabrasive cutter; a rock feeding into a rotation of the superabrasive cutter on the spinning wheel; and a plurality of sensors operably attaching to the spinning wheel and the rock to detect properties of the superabrasive cutter. The method of testing a superabrasive cutter may comprise steps of attaching a superabrasive cutter to a spinning wheel; moving a rock into a rotation of the superabrasive cutter on the spinning wheel; and communicably coupling a first sensor to the superabrasive cutter.

Laboratory assessment of PDC cutter design under mixed-mode conditions

A method of making a polycrystalline diamond compact includes mixing a diamond particle feed with a binder to form a mixture, forming the mixture into a precompact, heating the pre-compact in a non-oxidizing atmosphere to substantially drive off the binder, oxidizing the pre-compact in an oxidizing atmosphere at a temperature and for a time sufficient to burn off non-diamond carbon without overoxidizing diamond, and sintering the pre-compact at high pressure and high temperature to form a polycrystalline diamond compact. The method may also include oxidizing the diamond particle feed prior to mixing with the binder.

Polycrystalline diamond compacts having improved wear characteristics, and method of making the same

A cutting element and a method of making the superabrasive cutter are disclosed. The cutting element has a substrate and a superabrasive layer. The substrate has an inner face and an annular face. The inner face may have a center. The annular face may have a periphery. A superabrasive layer attaches to the substrate along the inner face and the annular face, wherein the inner face slopes outwardly and upwardly from the center at an angle ranging from between about 1&#xb0; and about 7&#xb0; from horizontal.

Polycrystalline diamond drill blanks with improved carbide interface geometries

A polycrystalline diamond compact (PDC) is fabricated using a process of delayed diffusion of a diffusion species (e.g., a metalloid) introduced from the back side of a cemented carbide further away from the diamond grit or from the flank side of the cemented carbide, as opposed to the side of the cemented carbide adjacent to the diamond grit. The process of fabricating the PDC includes depositing, in a metal container, a diamond grit, a cemented carbide, and a diffusion species, then applying a high pressure and high temperature (HPHT) to the contents of the metal container wherein (1) the binder of cemented carbide diffuses across the diamond grit, and (2) the diffusion species diffuses through the cemented carbide, and then through the diamond grit, thus providing a protective coating to the diamond grains of the PDC.
