    Abstract: A bond for a single layer metal bond abrasive tool can be easily chemically and electrochemically stripped from the metal core of a recovered used tool to facilitate reuse of the core. Relative to conventionally bonded tools, the speed of stripping the novel bond is quick, and the stripped core has a smooth, clean surface which needs only minimal mechanical repair prior to reuse. In one aspect, the novel bond consists essentially of a ternary bond composition of copper, tin and titanium, in which the copper and tin are pre-alloyed and the pre-alloy and titanium component are incorporated in the bond composition as fine particle size powders. In another aspect, the bond is a quaternary bond composition consisting essentially of copper, tin, titanium and silver. The powder components can be used dry or mixed with a fugitive liquid binder as a paste. The novel bond can be brazed at lower temperature than copper/tin/titanium bonds prepared otherwise. The bond composition forms a good melt at braze temperature that flows smoothly, evenly over a tool preform and provides consistent quality bonding of abrasive from tool to tool.

    Abstract: A tool manufactured by brazing a hard sintered body such as a diamond or cBN to a tool substrate through a bonding layer comprising at least one of Ti and Zr by 15-65 wt % and Cu. Two ridges of the tool substrate on both sides each has a first ridge adjacent to and aligned with a ridge of the hard sintered body and a second ridge provided nearer to an inscribed circle of the tool than is the ridge of the hard sintered body. Also, an upright side face and a bottom of each seating groove formed in the tool substrate intersect each other at an angle smaller than the intersecting angle between a back side and a bottom of each hard sintered body.

    Abstract: A snow plow skid shoe is formed of a mounting plate, which is bolted upon the rear face of a plow moldboard, and a skid plate having a bottom, ground engaging, surface. The plow is positioned so that the lower edge of the blade, which is bolted upon the forward face of the moldboard, rests upon the ground. Then the skid plate is supported upon the ground and is manually freely moved relative to the mounting plate until its ground engaging surface is leveled and aligned with the snow plow blade ground engaging edge and the closely adjacent plates form an acute angle. A rigid, fixing member, is moved into the acute angle space until it contacts both plates and then is welded to both plates for fixing the position of the skid plate. Thereafter, the mounting plate may be unbolted, for moving the skid shoe to an accessible place where the plates may be welded together along their adjacent edges and the fixing member to form a rigid, permanently adjusted shoe for the particular plow upon which it may then be re-bolted for use.

    Abstract: The present invention is a method of marking a metal device with an identification symbol or a serial number which is not detectable by a visual examination. The method of marking includes the steps of locally heating a specified area of the metal so that its microstructure is altered. For example, a laser, the intensity of which has been adjusted so as to maintain a designated area at a temperature within an appropriate temperature range for the particular metal, may be used to trace out either an identification symbol or serial number. The method is used in combination with the step of etching away the surface area of the metal device which includes both unaltered microstructure and altered microstructure with a selected chemical etching solution that will etch away the altered microstructure at a different rate than the unaltered microstructure thereby exposing the mark.
