Abstract: The present invention relates to powder metal articles that can be successfully welded to ferrous base materials. A formed part having an initial part density of at least 5.8 grams per cubic centimeter subsequently compressed is to at least ninety-two per cent (92%) of theoretical full density at a controlled area, including a contact area at which the part is adapted to be welded to the other material and at least a 0.025 inch wide margin of the surface laterally contiguous the contact area to a subsurface depth of at least 0.025 inch while retaining the initial part density throughout the balance of the article. Such increased densification is accomplished by applying inwardly directed, localized surface pressure against the controlled area of a formed powder metal part.

Abstract: A laminated article for electrical applications is disclosed which comprises at least two sheets of electrically isolated electrical steel each having a thickness of less than 0.020 inch, and an adhesive between adjacent sheets bonding the adjacent sheets to one another without creating significant compressive stress in the plane of the sheets. The adhesive is characterized by substantially instantaneous bonding at a temperature less than 750.degree. F.

Abstract: A system comprising a ferritic stainless steel substrate having a tightly adherent oxide coating and a catalytic material thereupon. The ferritic stainless steel is of a chemistry which forms a tightly adherent non-spalling scale suitable for application of a catalytic bearing material. It consists essentially of, by weight, up to 26% chromium, from 1 to 8% aluminum, from 0.02 to 2% hafnium, up to 0.3% yttrium, up to 0.1% carbon, up to 2% silicon, balance essentially iron.

Abstract: A method and machine are disclosed for screen printing acid-resist mirror inversion images in registration on opposite sides of a metal web with a degree of precision sufficient to permit the incorporation of screen printing techniques in the fabrication of lead frames, electromagnetic core laminations, and other metal plate products by chemical milling processes. A matched pair of upright screen stencils supported in spaced relation on opposite sides of the web is provided with a cooperable pair of squeegees for printing through the image areas of the stencils. The directly opposed squeegees are mounted on a common reciprocable carriage for conjoint movement such that printing on opposite sides of the web is effected synchronously. In preferred forms, a web drive is provided for incrementally advancing the web between the stencils and for holding the web under tension during printing.

Abstract: A flexible mechanical coupling for torque transmission is capable of being connected and disconnected by only manual manipulation. The collar of the coupling has diametrically opposed cutouts in its sidewall for loosely receiving complementally shaped resilient locking members which in turn are held in place by a sleeve telescopically disposed over the collar. Flats formed in the shaft beneath each cutout are engaged by the respective members for locking the shaft and the collar against relative rotation. A removable roll pin passing through the shaft and the resilient members restricts axial movement between the collar and shaft. The sleeve is releasably restrained in position over the locking members by a pair of manually removable elastic bands on the collar. One embodiment of the invention provides the manual connection feature for both shafts in the coupling, while in the preferred embodiment only one shaft in the coupling has this feature.
