An earth cutting tool can include one or more earth cutting devices. Each earth cutting device can include a plurality of inserts positioned within a body of the cutting device. The inserts can be tapered to correspond to a tapering of pockets defined in the body to facilitate insertion and attachment of the inserts to the body to avoid cracking of the body during brazing and/or heat treatment that may occur after the inserts are positioned in the pockets.

A valve seat installation tool is disclosed. The valve seat installation tool includes a force conversion shaft extending from a shaft front surface to a shaft rear surface along a central axis, a torque nut secured to the force conversion shaft adjacent to the shaft front surface, a head adjacent to the shaft rear surface and a pump adapter secured to the force conversion shaft between the torque nut and the head.

Valve seat installation tool system

A multi-component electro-mechanical flame spray deposition system is disclosed having a first electro-mechanical feeder and a second electro-mechanical feeder, each in communication with a mixing hopper, and wherein the mixing hopper is in communication with a powder nozzle having an orifice, and a combustion torch having an orifice, wherein the orifice of the powder nozzle is in juxtaposition to the orifice of the combustion torch. A method of using the multi-component electro-mechanical flame spray deposition system is provided for depositing substrates on or to articles of manufacture.

A valve seat assembly includes a body having an insert pocket with an axially extending inner surface and a radially extending bottom surface. The valve seat further includes an insert disposed within the insert pocket of the body. The insert includes an axially extending outer surface and a radially extending bottom surface for mating with the axially extending inner surface and a radially extending bottom surface of the insert pocket of the body. The axially extending inner surface of the body is formed with a non-zero reverse taper angle, A, for securing the insert within the insert pocket of the body. The axially extending outer surface of the insert is formed with a reverse taper angle, A, equal to or greater than zero degrees. A valve assembly includes a valve and the valve seat assembly in reciprocating contact with the valve.
