A cutting element includes a metallic carbide body, a first layer of polycrystalline diamond material, and at least one transition layer between the metallic carbide body and the first layer. The polycrystalline diamond material includes a plurality of interconnected diamond grains, first metal carbide particles, and a first binder material in interstitial regions between the interconnected first diamond grains, wherein the first metal carbide particles form a matrix in which the second diamond grains are dispersed and wherein the first metal carbide particles are present in the outer transition layer in an amount ranging from about 15 to 35 volume percent. The at least one transition layer includes a composite of diamond grains, second metal carbide particles, and a second binder material.

Sensor-enabled cutting elements for an earth-boring drilling tool may comprise a substrate base, and a cutting tip at an end of the substrate base. The cutting tip may comprise a tapered surface extending from the substrate base and tapering to an apex of the cutting tip, and a sensor coupled with the cutting tip. The sensor may be configured to obtain data relating to at least one parameter related to at least one of a drilling condition, a wellbore condition, a formation condition, and a condition of the earth-boring drilling tool. The sensor-enabled cutting elements may be included on at least one of an earth-boring drill bit, a drilling tool, a bottom-hole assembly, and a drill string.

A cutting element assembly includes a sleeve, a lining extending a distance axially from an end of the sleeve, and an inner cutter. The inner cutter has a cutting end, wherein the cutting end extends a depth from a cutting face, a side surface, and a body, wherein the body is at least partially disposed within the sleeve, and wherein the side surface of the cutting end interfaces with an interfacing surface of the lining.

A composite tungsten carbide insert (B, I) with heterogeneous composition and structure has a working part (W) and a non-working part (N). The working part (W) is made of a tungsten carbide material consisting of tungsten carbide powder and cobalt powder or nickel. The non-working part (N) is made of a low density tungsten carbide material consisting of titanium carbide powder, tungsten carbide powder, and cobalt powder or nickel powder. During pressing, the tungsten carbide material for the working part (W) and the low density tungsten carbide material for the non-working part (N) are weighed and added to a steel die successively for molding and then sintering. The non-working part (N) which accounts for most of the overall product volume has low density and less material consumption, and can greatly reduce the raw material costs of the product, significantly improving the performance-cost ratio of the insert (B, I).

A drill bit assembly for drilling a hole through earth, the drill bit comprising: a bit body extending between a first end and a second end along a longitudinal axis of the bit body with a connecting arrangement positioned at the first end of the bit body for coupling the bit body to a rotating shaft for providing rotational torque to the bit body; a cutting head including a leading tip portion for cutting into earth and a trailing receiving portion for receiving the second end of the bit body in an internal cavity defined by the receiving portion to allow the cutting head to be removably coupled to the second end of the bit body; a retaining arrangement to retain the second end of the bit body in the receiving portion of the cutting tip.

A method of positioning a slide for examination is disclosed. The method includes the steps of placing the slide in a carrier configured to retain the slide, placing the carrier in a cartridge configured to accept the carrier, coupling the cartridge to a microscope, and activating the microscope to automatically extract the carrier from the cartridge and position the carrier such that a portion of the slide is disposed within a field of view (FOV) of the microscope.

A cartridge is disclosed that secures and controls removal of carriers within one or more compartments. The cartridge employs a row of movable spacers biased by a spring and governed by a locking mechanism that selectively restricts or permits carrier removal. When locked, seated carriers are retained in place; when unlocked, carriers may be withdrawn in a controlled sequence. A travel-limiting feature ensures that only one carrier can be partially removed at a time, thereby preventing simultaneous extraction of multiple carriers and enhancing secure handling.
