Abstract: A method and apparatus for optimizing the drilling position of a multi-layer printed circuit board prior to drilling. 
     A template (115) having precisely located target holes (A',B',C',D') and fixture reference marks (118, 119) provides initial coordinate reference information for multi-layer printed circuit boards (25) to be inspected by x radiation. Each board (25) is processed by insertion into a holding fixture, examination of four quadrant target areas using x-ray sources (21-24) and detectors (26-29), digitization of the target area images in each quadrant, and computation of the optimum board position in a follow-on drilling apparatus. After optimization, three reference holes are punched along one edge of the board (25) to provide accurate fiducial positioning marks when the board is placed in the drilling apparatus.

Abstract: The process herein described provides the weaving of a manufactured product consisting of an upper fabric (2) made of cotton or any other suitable material and a lower fabric (3) with weft yarns (3a) made of wool and warp yarns (3b) interlaced with the weft yarns (2a) of the upper fabric (2). The weaving operation is followed by a printing step carried out on the upper fabric (2) of the manufactured product and by one or more teaseling steps on the lower fabric (3). Subsequent to each teaseling step there is a dimensional stabilization step of the manufactured product accomplished by a combined action of moistening, heating and tensioning the product, tensioning lasting till the end of the moistening and heating steps. A napping operation is also carried out together with the last teaseling step. By said process a blanket is obtained which comprises an upper fabric (2) with weft yarns (2a) interlaced with the warp yarns (3b) of a lower fabric (3). The lower fabric (3) has a teaseled and napped visible surface (6) and the upper fabric (2) a printed visible surface (7).

Abstract: When two 4-naphthoxyphenyl moieties are connected through a polar linking group, Y, it does not interfere with an oxidation process which results in dehydrogena­tive polymerization to yield polyarylene polyether (PAPE) polymers having a weight average mol wt greater than 10,000. Homo- and copolymers having a repeating unit in which a 4,4ʹ-di(1-naphthoxyphenyl) moiety is connected through its phenyl rings to a bivalent polar residue are descrbed. A specific monomer is selected from the group consisting of 4,4ʹ-di(1-naphthoxy)diphenyl sulfone (DNDPS, Y= SO₂) and, 4,4ʹ-di(1-naphthoxy)benzophenone (DNBP, Y= CO). Because the process provides thermoplastic PAPE poly­mers having a Tg in the range from about 250°C to about 350°C with excellent physical properties, the polymers are suitable for use in the fabrication of composites for aerospace vehicles subjected to elevated temperatures.
