Patent number: 5500272Abstract: Thin perforated sheets of titanium are interleaved between adjacently situated graphite/epoxy plies--in the area where metal fittings are to be installed. Epoxy flows through these perforations so as to achieve a gripping mechanism between the titanium sheet and the graphite/epoxy plies. The result is efficient transfer of load in the titanium to the composite fiber materials without suffering the cost penalty of extensive graphite/epoxy buildups (without interleaved titanium sheets). Epoxy plugs within the titanium sheet perforations bond to confronting surfaces of the graphite/epoxy plies and provide a fail safe gripping mechanism between the titanium sheet and adjacent graphite/epoxy plies to allow for the load transfer between the titanium sheet and the graphite/epoxy plies in the unlikely event that the shear bond between the faces of the titanium sheet and the graphite/epoxy plies becomes completely disbonded.Type: GrantFiled: January 11, 1995Date of Patent: March 19, 1996Assignee: Northrop Grumman CorporationInventor: Vincent T.

Patent number: 5484641Abstract: A method of fixing plastic reinforcing pins into non-woven filamentary material includes the steps of: (a) providing an elongated web of randomly-aligned synthetic fibers, (b) creating a repeating pattern of holes through the by a hole-punching mechanism having a plurality of heated punch heads maintained at a temperature above the melting point of the synthetic fibers, (c) conveying the web from the punching mechanism over a supporting belt such that the belt provides a closed bottom for each hole, (d) injecting a quick-setting liquid polymer into the holes with an injector mechanism having a plurality of liquid injector nozzles arranged in an identical pattern as the pattern of punch heads and operated in coordinated sequence with the punching mechanism, such that an injector nozzle is inserted into a corresponding hole, and (e) allowing the severed ends of the fibers to imbed into the liquid polymer before it sets.Type: GrantFiled: November 1, 1993Date of Patent: January 16, 1996Inventor: Martin J. Rotter

Patent number: 5472768Abstract: The present invention relates to a tubular section which may be constructed from a sheet having a pair of opposed edges. The opposed edges are releasably connectable such that the section may be stored in a relatively flat configuration. The screw fasteners used to connect the edges together may be restrained from rotation using for example a stringer element appropriately stabilised relative to the fasteners.Type: GrantFiled: November 1, 1993Date of Patent: December 5, 1995Inventor: Andrew P. Anson

Patent number: 5397625Abstract: Disclosed herein is a duo-functional nonwoven composite having a support layer with a top surface and a bottom surface separated by a thickness. On the bottom surface of the support layer is a fibrous nonwoven web with all or a portion of the fibers being formed from a material which is soluble in a fluid such as water. At least a portion of the fibers extend through the thickness of the support layer from the bottom surface and project beyond the top surface to give the top surface a cloth-like appearance. Upon wetting the top surface of the support layer by a fluid such as water, urine or menses, the soluble fibers begin to shrink and dissolve until all or a portion of the filaments have retracted back into and through the thickness of the support layer. In so doing, the applied fluid is transported substantially away from the top surface of the composite.Type: GrantFiled: November 24, 1992Date of Patent: March 14, 1995Assignee: Kimberly-Clark CorporationInventors: D. Keith Osteen, Hannong Rhim, Lawrence H. Sawyer, E. G. Varona, M. Chris Wanek, Kenneth Y. Wang

Patent number: 5273803Abstract: An apparatus and method for fabricating accurate, numerically defined curved surfaces and volumes comprising a skeleton framework having a plurality of bulkheads fixed in spaced relationship with each other, each of the bulkheads having an equal number of boreholes passing through the outer perimeter thereof so as to provide a set of selected boreholes. A flexible spline having a memory is passed through each set of mating boreholes and is secured with the boreholes after the splines have reached their static states. The resultant framework is encased in a cured polymer and the polymer is trimmed and faired between the outer edges of the splines.Type: GrantFiled: September 17, 1992Date of Patent: December 28, 1993Inventor: Michael Metcalf

Patent number: 5250342Abstract: An EMI shield is disclosed for providing EMI protection. The shield is lightweight, and easily moldable into complex shapes, having conductive mating surfaces provided on opposite sides thereof. The clean, highly conductive mating surfaces are part of an embedded aluminum wire mesh sandwiched between at least two face plies which add strength to the shield. By sandwiching the metal mesh alternately with a nonporous tape, and a barrier tape ply, clean conductive areas can be provided on either side of the shield, easing attachment to adjacent structures. During curing, the tapes prevent direct resin inclusion into the metal mesh. After curing, the nonporous tape is removed to expose the clean, highly conductive mating surfaces.Type: GrantFiled: April 16, 1992Date of Patent: October 5, 1993Assignee: United Technologies CorporationInventors: Charles F. Lang, Rocco R. DiGenova

Patent number: 5176946Abstract: A method of manufacturing a core for an electrical inductive device. A blind hole is provided through a stack of laminations into which an oil or an epoxy resin adhesive is placed. The blind hole provides a slow release for the oil to the outer surfaces. This obviates the contamination of the outer surfaces of the coil during manufacture as in the case with a dipping procedure. When the epoxy resin adhesive is employed in the blind hole, a wicking action takes place for better fastening of the laminations together. In another embodiment of the fastening feature, epoxy resin adhesive is molded to the outside of the end piece laminations as well as through a passage in the laminations. An improved resulting core is also provided.Type: GrantFiled: May 10, 1991Date of Patent: January 5, 1993Assignee: Allen-Bradley Company, Inc.Inventor: Christopher J. Wieloch
