Abstract: A method of coating a metal substrate with a protective metal coating by melting the coating, heating the surface only of the substrate with a high frequency induction heater to the melting temperature of the coating or greater and substantially immediately applying the molten metal coating to the heated substrate prior to penetrate of the heat through the substrate.

Abstract: A retro-reflective system for increasing the safety of a railroad crossing includes at least one railroad crossing panel. A sealer is applied to a prepared surface of the railroad crossing panel. An adhesive applied over the sealer after the sealer is partially cured adheres a retro-reflective material thereto. The retro-reflective material increases visibility of the railroad crossing. Anti-skid elements may also be applied over the adhesive, to provide enhanced traction for vehicles or pedestrians traversing the railroad crossing.

Abstract: An improved method of shipping and installing a new hard drive in a computer comprising the steps of packaging a new hard drive in an improved static dissipation bag having a conductive coating on its exterior surface; boxing the packaged new hard drive in a shock-absorbing medium within a transportation box, connecting the new hard drive to the computer, transferring the data from the computer to the new hard drive, disconnecting the new hard drive from the computer, grounding the static dissipation bag to the computer and to an operator, removing the new hard drive from the bag and transportation box, and installing it in the computer.

Abstract: An improved method of installing a new hard drive in a computer comprising packaging a new hard drive with a connected hard drive connector assembly having a hard drive PCMCIA connector in a static dissipation bag having a conductive coating on its exterior surface; grounding the static dissipation bag by connecting the bag to the computer and to an operator, extending the PCMCIA connector outside the bag, connecting the new hard drive via the PCMCIA connector to the PCMCIA or equivalent port of a computer, transferring the data on the computer to the new hard drive, disconnecting the PCMCIA connector from the computer, removing the new hard drive from the static dissipation bag, disconnecting the hard drive connector assembly from the new hard drive, and installing the new hard drive in the computer.

Abstract: The method for coating the seam of a welded tube of this invention includes applying a mixture of the desired protective metal coating in powdered form and a liquid flux over the internal surface of the welded seam with the welded seam located in a lower portion of the tube, then heating the welded seam to the melting temperature of the protective metal coating, melting the metal coating which flows over the seam forming an adherent metallurgical bond. The preferred apparatus includes a wand which extends between the opposed edges of the open seam tube in the welding apparatus and extends axially through the tube to overlie the welded seam spaced from the welding apparatus. The wand includes three conduits transmitting the powdered protective metal coating, liquid flux and nonoxidizing gas to the applicator which includes a nozzle which atomizes and sprays the liquid flux over the internal surface of the seam and which combines with the powdered protective metal coating to form a paste.

Abstract: An improved method of coating the welded seam of a metal tube comprising heating the weld area only of the metal tube to a first temperature which is less than the melting temperature of the protective metal coating, applying the protective metal coating over the seam and heating the entire tube preferably with a full body induction coil to a second temperature which is at least equal to the difference between the first temperature and the melting temperature of the metal coating, such that the temperature of the seam area is heated to a temperature equal to or greater than the melting temperature of the metal coating, whereby the metal coating firmly adheres to the welded seam.
