Patent number: 5958506Abstract: A method of restoring damaged portions of paper (Japanese and machine-made) paintings and calligraphic works, which does not require a high degree of skill, retains the original thickness of the work, improves durability after restoration and ensures neutralization of the work and simplification of any further restoration. A raw restoration liquid prepared from paper stock, water and an adhesive such as a liquid extract of Hibisci radix and optionally a colorant is placed in a vat. A target paper work to be restored is laid over a cloth or paper-making sheet which is laid over a filtering sheet-like member fitted into a paper-making frame. The paper-making frame is soaked in the raw restoration liquid so that the fibers contained in the raw restoration liquid are filled into the damaged portions of the paper work. The cloth or paper-making sheet is removed from the paper-making frame while the fibers are dried to the point of dampness.Type: GrantFiled: January 13, 1998Date of Patent: September 28, 1999Inventor: Mitihiro Kihara

Patent number: 5954901Abstract: A method and apparatus for repairing dimpled or cracked windshields is set forth. One portion of apparatus utilizes a suction cup, a laterally extending support member, three adjustable legs to level the support member approximately parallel to the windshield, and a threaded housing in inserted therethrough to bear against the windshield. The housing incorporates a plunger which operates as a syringe to inject a fluid resin for repair. On the opposite face, a set of suction cups holds a support member so that the end face of a bolt can be moved against the windshield to slightly bow the back side of the damaged area.

Patent number: 5948505Abstract: The invention relates to a composite comprising a thermoplastic resin and a glass fabric that can be used in the form of a linear extrudate as a structural member or as a repair unit. The resin glass fiber composite structural member can be manufactured in an extrusion process. The linear extrudate can have a cross-section of any arbitrary shape or can be a regular geometric shape. The profile is made by first preforming the glass fabric into a useful shape, combining the preform fabric with melt resin and extruding the resin and glass fiber in a useful shape. When contacted with melt resin, the glass fiber becomes intimately contacted with and substantially coated with the melt resin.Type: GrantFiled: March 28, 1997Date of Patent: September 7, 1999Assignee: Andersen CorporationInventor: Giuseppe Puppin

Patent number: 5932046Abstract: A method for manufacturing a fabric covered cushion includes the steps of coating one side of a stretchable fabric with gel/foam in order to make said fabric resistant to passage of air therethrough, disposing the coated fabric over a mold adapted for vacuum forming the cooled fabric and positioning at least one strap member in the mold with a portion of the strap member extending beyond a boundary of the mold. Thereafter, a vacuum is applied between the mold and the fabric in order to stretch the fabric and cause intimate contact between the fabric and the mold. An additional volume of foam is deposited on the fabric coating while the vacuum is being applied in order to enable bonding between the additional volume of gel/foam, the coated fabric and strap member. The additional gel/foam is allowed to set and bond with the fabric and the strap member, and a fabric covered cushion is removed from the mold having the selected contour.Type: GrantFiled: May 15, 1997Date of Patent: August 3, 1999Inventor: Paul M.

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: 5928465Abstract: The invention relates to a method and an apparatus for the production of a plate with depressions or apertures which is coated on at least one side. Plates of this kind are employed, for example, as passage-containing plates in hydraulic blocks for ABS/ASR/VDC systems, the depressions or apertures serving as passages or holes and the coating being a seal. In this invention the depressions or apertures are formed in an uncoated plate and then the plate is coated. As a result, the life of the machining tools is extended, the machining tolerances become smaller and the rate of machining can be increased.Type: GrantFiled: August 18, 1997Date of Patent: July 27, 1999Assignee: Robert Bosch GmbHInventor: Guenther Schmidt

Patent number: 5916405Abstract: A speaker enclosure having a substantially seamless rigid outer skin, a middle sound absorbing layer, and a substantially seamless flexible inner skin. The speaker enclosure is comprised of two basic parts, a box section and a baffle section where each of these sections include the rigid outer skin, the middle sound absorbing layer and the seamless flexible inner skin and are made according to the same method. The outer skin is formed from multiple layers of resin impregnated carbon fiber, the middle sound absorbing layer includes pieces of honeycomb material and the inner layer is formed from multiple layers of resin impregnated fiberglass. The layers of material are arranged in a substantially seamless manner into a mold and then cured by vacuum bagging and heating thereby producing a strong, lightweight speaker enclosure made of materials which dampen the transmission of errant sound waves in the enclosure and thereby minimize distortion of the sound signal produced by the speaker.Type: GrantFiled: February 12, 1996Date of Patent: June 29, 1999Assignee: Southern California Sound Image, Inc.Inventors: Ross Ritto, Michael Adams
