Patent number: 7513968Abstract: Using a ¼ inch end mill a grid pattern of one inch squares or lands separated by concave troughs or grooves 0.025 inches deep is milled on to the surface of a one quarter inch thick magnesium plate. A conductive barrier such as a titanium foil is then laid over the magnesium plate, and is then pressed into the pattern with a one inch thick 80 durometer rubber sheet. Pressure of 250 pounds per square inch is then applied to the rubber to create indentations in the foil creating the same pattern as the one on the magnesium plate. The foil is then removed. An electrically conductive adhesive is then screen printed on the magnesium lands only, avoiding the grooves. The titanium foil is oriented to the pattern on the magnesium plate and mated to the magnesium plate by applying 200 pounds per square inch of pressure.Type: GrantFiled: July 11, 2005Date of Patent: April 7, 2009Assignee: The United States of America as represented by the Secretary of the NavyInventors: Earl S.

Patent number: 6131530Abstract: A platform for servicing of vertically positioned missiles in a ballistic ssile submarine. The platform includes a vertically inclined rail and a horizontal frame. In the frame there is a first element having a first and a second end superimposed over the inclined rail. This first element is movably mounted directly on the rail at the first end and movably mounted in vertically spaced relation above said inclined rail at said second end. At least one second element is spaced laterally from the first element to enclose a missile tube access opening. A vertical support means is also positioned in opposed relation to the inclined rail. The vertical support means is adjustable to the curved hull surface of the submarine to maintain the frame horizontal. The platform is constructed from a lightweight material such as aluminum, and it can be carried and assembled by two men for the efficient servicing of VLS equipped submarines and other similar vessels.Type: GrantFiled: December 21, 1998Date of Patent: October 17, 2000Assignee: The United States of America as represented by the Secretary of the NavyInventors: Leonard E.

Patent number: 5691482Abstract: An apparatus for testing adhesive shear strength having a cylindrical adhve bond between test specimens which is subjected to pure shear. The test specimens are two cylindrical rods. One rod has a bore and counterbore reamed into one end along its longitudinal axis. The other rod has a diameter essentially equal to the diameter of the bore. The adhesive to be tested is placed within the bore and counterbore and the smaller diameter rod is inserted into and seated at the base of the bore. The adhesive fills the space between the smaller rod and the counterbore, creating a uniform, cylindrical layer of adhesive between the exterior surface of the smaller rod and the inner surface of the counterbore. When the adhesive cures, the assembly is subjected to a tensile load along its longitudinal axis, tending to pull the inserted rod from the bore and subjecting the cylindrical adhesive bond to a pure shear load.Type: GrantFiled: July 11, 1996Date of Patent: November 25, 1997Assignee: The United States of America as represented by the Secretary of the NavyInventors: Earl S. Nickerson, Jr., Wayne C. Tucker

Patent number: 5535904Abstract: The present invention relates to an improved etchant for iron materials and method for etching iron materials. The etchant is an aqueous solution of ferrous chloride and phosphoric acid. The etchant preferably consisting of essentially of 20.6 gm FeCl.sub.2 .multidot.4H.sub.2 O, 88 ml H.sub.3 PO.sub.4 (concentrated 85%) and deionized water sufficient to make a 500 ml solution total. The method of etching includes the steps of preparing the surface of the iron material to be etched by degreasing and abrading the surface and etching the surface by immersing the iron material in the ferrous chloride and phosphoric acid solution. After the surface has been completely dried, an epoxy material may be bonded thereto. The method and etchant of the present invention provide an iron surface which bonds well with an epoxy, but does not destroy any existing epoxy bond in the material as would be present in a wound iron core material bonded with an epoxy cement.Type: GrantFiled: January 25, 1995Date of Patent: July 16, 1996Assignee: The United States of America as represented by the Secretary of the NavyInventor: Wayne C.
