摘要： Ferrous metal articles, such as stainless steel articles, characterized by at least one brazed joint, in which the braze is a non-ferrous alloy are aluminized by first selectively coating the braze alloy with an aluminide-forming metal, such as nickel, and then thermally diffusing aluminum over the entire surface of the article including the selectively coated braze, such that a sacrificial corrosion resistant coating is produced wherein the aluminum coating on the ferrous metal surface is characterized by the presence of iron aluminide, and wherein the aluminum coating on the metal-coated braze is characterized by the presence of metal aluminide, such as nickel aluminide. The aluminide coatings are further enhanced by the application of a non-metallic coating, e.g., a conversion coating.

摘要： A door stop for a laterally movable door which is hung on a building wall includes a bracket mounted near the forward edge of the door on the surface toward the wall and a slide member which is horizontally slideable in the bracket and has an offset stop bar at its front end and ears at its rear end. As the door nears closed position the stop bar engages one door jamb, and the door continues to move until the bracket abuts the stop bar. The door is stopped in open position when the stop bar is engaged with the other door jamb and the bracket abuts the ears. A latch strike on the first jamb engages the stop bar to ''''snug'''' the door against the wall, and to permit the door to be locked shut.

摘要： An agricultural implement is disclosed having a center frame and wings hinged to either side thereof on which are supported soil working tools. First remotely controlled hydraulic means actuate links which swing the wings between stable horizontal ''''transport'''' positions at rest on the center frame and horizontal ''''field working'''' positions to opposite sides of said frame. The links hold the wings against movement when in their ''''transporting'''' position and allow the wings freedom to swing when in their ''''field working'''' position to follow the contour of the field over which the implement is moved. Further hydraulic means operate other linkages which include screw-threaded swivel links on or by the axes about which the wings swing to interconnect the soil working tools and/or pivotally mounted wheels on the wings with those on the center frame so that the tools on the wings move into their working positions with corresponding movement of the tools on the center frame under the remotely controlled operation of the further hydraulic means.

摘要： A method is provided herewith for the production of multi-metal diffusion coatings on metal articles providing prolonged protection against chemical or galvanic corrosion of the surface of the coated article during prolonged exposure to corrosive conditions, and particularly high saline content marine atmospheres, especially where the protective coating is also subjected to mechanically erosive and abrasive environments, with the multiplicity of coating metals being selected so that the combination thereof provides a coating varying through the thickness thereof from outer surface toward the interface of coating layer and coated article so that the mechanical resistance to chemical corrosion is greatest at the outer surface but decreases as the coating thickness is eroded away, while the components of the coating offering sacrificial or cathodic protection are more concentrated adjacent the coating-article interface so that cathodic protection of the coated article increases as the coating is removed by abrasion or erosion. As illustrative, the outer coating surface includes a high concentration of metallic components inherently resistant to saline corrosion and/or abrasion, although offering less cathodic protection for the coated article; while inner layers of the coating are rich in metallic components offering high sacrificial or cathodic protection, although less erosion or saline corrosion resistance.

摘要： A powder metallurgy produced wear resistant magnetic pole piece for use as a pickup head with magnetic playback tapes is provided made of a magnetically soft ferrous alloy containing effective amounts of silicon and aluminum. A powder of the alloy is oxidized to provide a thin oxide on the particles thereof. The powder is then hot pressed in vacuum at an elevated temperature into a dense sintered body. The presence of oxide in the grain boundaries confers wear resistant properties to the alloy. An oxygen content of about 3,400 to 4,400 ppm is preferred.

摘要： The invention contemplates a vane-twist measuring or gaging instrument in which the overall twist of the vane is assumed to be indicated by the angular relation between a reference alignment, taken on one buttress surface, and a measured-offset alignment, taken on the corresponding surface of the other buttress for the same vane. Basically, a reference plane is established for the reference surface of the first abutment, as by using two fixed and precisely positioned spaced point-contact elements, and a gage carried by the instrument near the other buttress senses the inclination of the other buttress (with respect to the reference plane) when the other buttress is applied against a single, or third, fixed point of support on the instrument. In one form, the third support point is established by an elongated bar, with provision for central pivotal support, so that its angular orientation about the pivot may reflect contact with, and therefore slope of, the other vane buttress; in another form, the third support point is a fixed abutment near one end of the other buttress, and a probe responds to a given location near the other end of the buttress when the vane is applied to the three fixed support contacts.
