    摘要： A rectangular shaped cutting tool having an upwardly, forwardly and sidewise opening V-shaped recess formed in one side face, with the edges of the V being uniformly sloped to form an acute angle with the inner wall of the recess, and a replaceable triangular shaped cutting insert formed of a hard, brittle metal, having its edges bevelled to correspond to the slope of said edges, vertically positioned in the recess and jammed downwardly and against the recess inner wall by both an upper releasable clamp and by cutting forces upon the exposed cutting corner of the insert. The uniform slope of the recess edges and its three openings permit the interchangeable use of inserts which are inaccurate or slightly variable in thickness and edge length. The improvement wherein the insert edges are bevelled from its opposite faces to define a cental raised ridge along its edges, rather than from one side, to allow the insert to be used in either left or right hand insert holders interchaneably.

    摘要： In a method of producing an electrode comprising a layer of an electrocatalytic material on a substrate, at least one liquid medium containing a precursor to the electrocatalytic material is atomized to produce droplets containing the precursor and the droplets are entrained in a stream of carrier gas moving in a first direction. The droplets entrained in the carrier gas stream are then heated to remove the liquid medium and convert the precursor to particles of the electrocatalytic material. The electrocatalytic material particles entrained in said carrier gas stream are then brought into contact with the substrate, whereby the electrocatalytic particles are separated from the carrier gas and collected on the substrate. By imparting relative movement between the substrate and the carrier gas stream in a second direction substantially perpendicular to the first direction a continuous layer of the electrocatalytic material can be progressively deposited on the substrate.
