Patent number: 5952072Abstract: This invention provides a method for restoring at least one means defining a railroad spike hole located in a used railroad tie. In this way, the restored railroad tie can be reused in subsequent rail replacement operations. The restored railroad tie is capable of having a railroad spike penetrate and be retained within the confines of the restored railroad spike hole without substantial bending problems. The used railroad tie provided has at least one spike hole located therein. In each the means defining a railroad spike hole is formed a polymeric plug. The polymeric plug comprises a substantially non-foaming, non-cellular polymeric material. The polymeric material preferably comprises a polyurethane. The polymeric plug infiltrates and tightly bonds with the railroad spike hole to prevent moisture infiltration. Thus, substantial tie rot due to moisture is impeded, and the leaky railroad spike hole is effectively and efficiently dammed to enable complete filling thereof.Type: GrantFiled: June 9, 1997Date of Patent: September 14, 1999Assignee: Willamette Valley CompanyInventors: Scott Adams Colby, Robert Mark Loomis, Amy Laverne Clement

Patent number: 5928448Abstract: The present invention is a dowel-adhesive method for repairing ceramic matrix composites. The dowel adhesive method embodied in the present invention incorporates both adhesive and mechanical bonding of a patch to a damaged CMC surface area. The damaged area is first identified and then pre-processed. Next, a CMC patch plug is produced and adhesively and mechanically bonded to the pre-processed area. Mechanical bonding is accomplished with dowel pins and corresponding dowel pin holes in the patch plug and the panel. The dowel pins anchor the CMC patch plug to the panel. Adhesive bonding is accomplished by placing a ceramic adhesive between the patch plug and the panel. Also, the dowel pins are adhesively bonded within the dowel pin holes of the plug and the panel. The ceramic adhesive is set by a low temperature cure (if required) and a high temperature firing.Type: GrantFiled: November 1, 1997Date of Patent: July 27, 1999Assignee: Northrop Grumman CorporationInventor: David Eric Daws

Patent number: 5139840Abstract: A trapezoidally-shaped rubber patch for patching the sidewall of a radial-ply tire with broken or damaged cords. The rubber patch has a first layer of rubber containing radial metallic cords and at least one second layer of rubberized fabric with synthetic cords under the first layer. Beneath the second layer is at least one third layer of rubber. The patch has a knurled attachment surface for attaching it to a coresponding knurled tire attachment surface. The rubber patch also has a trapezoidally-shaped rubber plug extending outwardly from the attachment surface. The rubber plug fits into a window which is cut in the sidewall of the tire in the area of the broken or damaged cords. The first layer of rubber is raised with respect to the attachment surface. The first layer of rubber is as wide as the base of the plug in the area beneath it.Type: GrantFiled: July 14, 1989Date of Patent: August 18, 1992Assignee: R.F.P.

Patent number: 5104708Abstract: An improved wood patch, in combination with a slot formed in a blemished wooden surface, and apparatus and method of manufacture thereof. The improved wood patch has, where the wooden surface to be repaired is horizontal, three faces: a flat horizontal exterior face, a flat vertical interior face, and an angled arcuate interior face. The patch has both a larger vertical radius of curvature and a larger angle between the flat vertical interior face and the angled arcuate interior face than the slot. Apparatus for manufacture includes a router utilizing a double router bit having a straight cutting edge oriented perpendicular to the axis of rotation of the bit and an angled cutting edge oriented at an angle to the straight cutting edge.Type: GrantFiled: March 23, 1990Date of Patent: April 14, 1992Assignee: Arthur H. FitzgeraldInventor: David L. Murphy

Patent number: 5102706Abstract: Substantially self supporting composites of glass pieces are made without having to cover the edges of the glass pieces with lead or copper tape that overlaps the sides of the glass pieces. The composites can be two or three dimensional assemblies. The method of making the composites comprises arranging a plurality of individual precut glass pieces with uncovered edges in a pattern with a flexible material adhering to surfaces of adjacent glass pieces, providing gaps between the glass pieces to expose edges of adjacent glass pieces, and applying a bonding agent in the gaps to rigidly bond the edges between the adjacent glass pieces but not to overlap onto the surfaces of the adjacent glass pieces.Type: GrantFiled: August 7, 1990Date of Patent: April 7, 1992Inventor: Richard C. Latte

Patent number: 5087496Abstract: A self-adhesive stocking patch for mending a nylon stocking. In its broadest aspects, the stocking patch comprises a thin resilient element of a shape and size to approximate typical tears occurring in nylon stockings. Adhesive attachment means is affixed to the element for securely attaching the element to portions of the nylon stocking adjacent to such a tear. The adhesive attachment means includes at least one piece of synthetic material of the type that adheres when pressed together with nylon (i.e. VELCRO.TM.). When applied to the stocking the patch provides an expedient means for temporary repair.Type: GrantFiled: February 14, 1991Date of Patent: February 11, 1992Inventor: Michel Bouchoucha

Patent number: 5084318Abstract: An overlay structure is provided for resurfacing a bowling lane. The structure includes a relatively thick homogeneous laminate sheet having a print layer to simulate the appearance of a wood bowling lane. A plurality of mechanical fasteners are positioned in respective recesses in the upper surface of the sheet and extending through the sheet for securement to the lane. Plugs are force fit into the recesses to hide the mechanical fasteners. The plugs are fabricated similarly to and have the same appearance as the print layer of the sheet.Type: GrantFiled: November 8, 1990Date of Patent: January 28, 1992Assignee: Brunswick CorporationInventors: Michael F. Stirling, Michael G. Gautraud, William C. Murphy
