Patent number: 6645549Abstract: A process for providing bond enhancement and an etch resist for a printed circuit board is provided. A sheet comprising at least a layer of copper is immerses in a first immersion tin solution comprising a tin metal and a complexing agent in an acidic medium for a time sufficient to deposit a first heavy tin deposit on the sheet. The sheet is then immersed in a second immersion tin solution comprising stannous tin ions and stannic tin ions and a complexing agent in an acidic medium for a time sufficient to deposit a second thin tin deposit on the sheet. The second thin tin deposit has a thickness less than a thickness of the first heavy tin deposit. A rough surface texture providing mechanical adhesion sites results. The board is then treated with a coupling agent, such as silane, for enhanced bonding to a subsequent epoxy or other polymer prepreg. Additionally, the first heavy tin deposit may serve as an etch resist in subsequent fabrication of the provided circuit board.Type: GrantFiled: October 11, 2001Date of Patent: November 11, 2003Assignee: Parlex CorporationInventors: Darryl J. McKenney, Arthur J. Demaso, Kathy A. Gosselin, Craig S. Wilson

Patent number: 6645565Abstract: A coated textile fabric is disclosed for manufacturing an air holding device for a vehicle restraint system, including a base woven, knitted or non-woven base textile fabric having a first surface and a second surface. The base textile fabric is completely or partially coated with an adhesive polyurethane to form a first coating layer, the first coating layer being coated with a second composite coating layer. The second composite coating layer is preferably a polyurethane, a polysiloxane, and an epoxy resin which acts as a filler and adhesion promoter. A third coating layer is formed of a polymeric polyurethane material coated on the second composite layer. A method of producing the coated textile fabric is also disclosed. A heat sealing die for forming sealing beads to seal such coated textile fabrics to form air holding devices is also disclosed.Type: GrantFiled: January 2, 2002Date of Patent: November 11, 2003Assignee: Bradford Industries, Inc.Inventor: Manuel J.

Patent number: 6635143Abstract: A token is manufactured using a combination of minting or casting operations and printing operations. The token comprises a metal base material that is minted or cast to the size and shape desired including embossed or debossed areas at selected locations on the token. In selected recessed or countersunk portions of the token, there are provided thin disks of material capable of carrying printed material such as single-colored or multi-colored pictures or indicia. The imprinted disk portions of the token are covered with a first protective coating and, optionally a second protective coating, that eliminates wear and tear on the printed areas of the token. Additionally or alternatively, the entire token can be covered with an outer coating to minimize wear and tear and preserve the unique designs carried by the token.Type: GrantFiled: December 20, 2002Date of Patent: October 21, 2003Assignee: Independence Mint, Inc.Inventors: Stanley Zurawski, Scott Martin, James Warren
