An electrode for a plasma arc torch includes a generally cylindrical elongated body formed of an electrically conductive material. The elongated body includes a proximal end that connects to a power supply and a distal end that receives an emissive element. The electrode can include a flange that is disposed about a surface relative to the distal end of the elongated body, extends radially from the surface of the elongated body, and is utilized to establish a uniform gas flow distribution of a plasma gas flow about the distal end of the elongated body. The electrode can include a contact element that is in electrical communication with the proximal end of the electrode. The contact element includes seating portion that has an outer width that is greater than the outermost diameter of the electrode body and is configured to position the contact element within the plasma arc torch.

Apparatus and method for securing a plasma torch electrode

A connector component is provided for assembly into a torch. The connector component comprises a body that includes a proximal end and a distal end disposed along a longitudinal axis. At least two thread regions are disposed radially about the longitudinal axis on a surface of the body near the proximal end. Each thread region includes at least two parallel threads disposed on the surface of the body. In addition, at least two smooth regions are each disposed radially about the longitudinal axis between a pair of thread regions on the surface of the body.

A mechanism for indexing the movement of a firearm cylinder to load and unload cartridges from a plurality of cartridge-receiving chambers in the cylinder. The firearm may generally comprise a cylinder, a supporting structure rotatably carrying the cylinder and a loading gate cutout. The indexing mechanism may comprise a cylinder indexing member, which in one embodiment may be a stop pin. The cylinder is configured to be stoppingly engaged by the indexing member when the cylinder is rotated in a first direction to align a cartridge-receiving chamber with the loading gate cutout in the frame, thereby creating an indexed position of the cylinder. Preferably, a plurality of indexed positions are created to allow each chamber to be aligned with the loading gate cutout for loading and unloading cartridges. In one embodiment, the cylinder is further freely rotatable in a second direction opposite the first direction without stopping engagement between the cylinder and indexing member. The mechanism may further include a pawl which is moveable into and out of engagement with the cylinder for advancing the cylinder as the firearm is discharged.
