Adolphe A. Bragard has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for producing a metal product having improved lustre after painting
    Patent number: 5044076
    Abstract: A metal product, such as cold rolled steel sheet, has a surface comprising a plurality of flat, smooth facets which are preferably 50 to 200 .mu.m across and which make up at least 30% of the area of said surface. The facets may be formed either by pressing a network of valleys in a flat, smooth surface or by flattening the peaks of a rough surface.
    Type: Grant
    Filed: January 29, 1990
    Date of Patent: September 3, 1991
    Assignee: Centre de Recherches Metallurgiques--Centrum voor Research in de Metallurgie
    Inventors: Jean R. Crahay, Adolphe A. Bragard
  • Metal product having improved luster after painting
    Patent number: 4917962
    Abstract: A metal product, such as cold rolled steel sheet, has a surface comprising a plurality of flat, smooth facets which are preferably 50 to 100 .mu.m across and which make up at least 30% of the area of the surface. The facets may be formed either by pressing a network of valleys in a flat, smooth surface or by flattening the peaks of a rough surface.

    Inventors: Jean R. Crahay, Adolphe A. Bragard
  • Surface treatment of a rolling mill roll
    Patent number: 4850089
    Abstract: The surface of a rolling mill roll is coated with a coating comprising a metallic substance and is then marked by means of an intermittent laser beam. As a result, micro-craters are formed which penetrate the roll and which have rims containing components from the roll and the coating. The longevity of the roughness of the roll can thereby be enhanced.

    Date of Patent: July 25, 1989
    Assignee: Centre De Recherches Metallurgiques-Centrum Voor Research In De Metallurgie
    Inventors: Guy Monfort, Jean Crahay, Adolphe Bragard
  • Process for marking the surface of a rolling mill
    Patent number: 4806731
    Abstract: A rolling mill is rotated while microscopic dents with peripheral ridges are formed by an intermittent laser beam in the presence of a gas jet directed at the beam impact zone. The output and the angle of incidence of the gas jet are controlled and microscopic dents are formed with a ridge on only part of their periphery. Steel sheet cold-rolled by means of such a roll has uniformly distributed hollows, each hollow partially surrounding an elevation.

  • Continuous measurement of the surface roughness of a cold-rolled product
    Patent number: 4803374
    Abstract: A light beam, e.g. from a laser, is transmitted onto the surface of a cold-rolled product such as steel strip. The light beam has a wavelength at least equal to the maximum roughness of the product surface. The reflected light energy is measured, preferably in the specular direction with respect to the incident beam; the surface roughness is deduced from that measurement. The light beam may be interrupted to provide two beams alternately incident on the same spot at different angles.

  • Method and device for improving the properties of thin steel plates
    Patent number: 4329562
    Abstract: In order to improve the surface characteristics of steel structure, it is oposed according to the invention to make at least one roll of a rolling-mill with a motif or pattern of motifs. The invention also includes apparatus for marking the roll which includes means for driving the roll marking device itself from the roll so that proper synchronization between the movements of the roll and marking device is achieved.
