    摘要： The invention is an extrusion device comprising an interleaving block portion. The interleaving block portion includes at least two first chambers, each first chamber including a width, a length, a height, and an input aperture. The length dimension of the first chambers are generally parallel. An output aperture is included in each first chamber, the output aperture is wider and shorter in height than the input aperture. A series of first distances are defined between the input aperture to points along the output aperture. A die portion is included in the extrusion device. The die portion has a laminate chamber having a height dimension. The height dimension of the laminate is disposed generally perpendicular to the length dimension of the first chambers. An output is disposed at one end of the height dimension. The laminate chamber is disposed so as to be in communication with the output apertures of the parallel first chambers.

    摘要： A driving tool for an elongated fastener of ferro-magnetic material, including an elongated hollow tubular body reciprocably receiving a driving rod having an impact end and a drive end. The drive end is characterized by an internal cavity receiving an Indalloy permanent magnet, the open end of the cavity being closed by a magnetic head, or pole piece, in such a manner that the axial impact forces imparted to the drive rod are transmitted substantially entirely to the magnetic head and not through the magnet. The Indalloy magnet is utilized within the drive end of the drive rod so that its magnetism will be retained, even if fragmented.
