    Abstract: A method for repairing a multi-layered damage area in a multi-layered composite structure. The method first includes obtaining depth measurement data, and obtaining topographical measurement data by laser scanning the surface of the damage area. This depth measurement data and topographical measurement data are inputted into a microprocessor along with thickness data of each layer. All inputted information is correlated among itself to thereby internally produce a three-dimensional damage area display-replica and interpolate a two-dimensional pattern of each layer of the damage area and of the surface of the damage area. The damage area is removed by first projecting a two-dimensional laser pattern of the damage area thereat on the surface of the structure, and thereafter manually removing the area to produce a void. Repair is accomplished by projecting onto respective replacement material a two-dimensional laser image pattern of each layer and manually cutting that layer according to the appropriate pattern.

    Abstract: A method for engraving an image pattern onto an impression die plate utilizes laser engraving and acid attacking techniques. In one embodiment, a brass plate is provided having a nickel coating thereon. A laser removes selected portions of the nickel coating according to a preselected image pattern so as to expose the underlying portions of the brass plate. Upon immersion of the plate into an acid bath, the acid attacks the exposed plate portions so as to present depressions in the plate. Upon removal of the plate from the bath a series of depressions and remaining coating portions on the plate present undulations thereon corresponding to the desired pattern image. This image is then impressed onto a medium, e.g. as a foil or the like. Various materials may be used for the plate, coating and acid bath. An electrically charged chrome coating may also be used with a non-electrically charged chrome being the acid bath.

  • Patent number: 5782026
    Abstract: A number of non specific, preexisting images are combined using an optical process of masking that (for purposes of clarity the following assumes 3 images are used) removes 2/3 of the first image in a sequential/lenticular pattern, replacing the removed image segments with 1/3 of each of the other two images also sequentially. These combined images are then separated by thin black separation lines using a special burning mask. This series of images and black lines is then visually decombined through the use of a clear thickness of material sandwiched together with the combined transparency and, using a non opaque adhesive, to a decombining mask in registration. This product is then able to be trimmed down and inserted into any preexisting light box. The product when back lit and viewed from the front creates the illusion of 3 complete, separate and sequential, non ghosting images that appear separately depending upon the viewers angle in relationship to the horizontal plane of the standing image.

  • Patent number: 5783005
    Abstract: A method is provided for producing a composite work from a single two-dimensional work having an image thereon. A flat backing member is provided having generally the same shape and size as the two-dimensional work. The work and the backing member are bonded together to form a work piece. The work piece is cut to define a geometrically shaped center section and a separate perimeter section, thereby breaking the image of the two-dimensional work regardless of individual sculptural components of the work so that each of the sections displays the respective portion of the broken image. The center section and border section are then assembled such that the continuity of the image formed by the sections is broken.

  • Patent number: 5506607
    Abstract: The 3-D Model Maker of the present invention is a device that builds three dimensional models of computer generated (e.g., CAD) structures by vector plotting layer-upon-layer applications of solidifiable substances. The layers are formed by expelling minuscule beads of the substances in liquid or flowable phase onto a platform from one or more jets, the jets and platform being relatively movable in X, Y and Z coordinate system. The beads are deposited along vectors, during X/Y relative movement, on the stage, one at a time, layer-upon-layer, to build the model. The jets and platform are moved relatively to one another in accordance with instructions from the computer (controller) to form each layer in the X-Y plane (in a manner analogous to an X-Y vector plotter) and either the stage or the jets may move in the Z direction to allow the jets to form subsequent layers.

  • Patent number: 5496683
    Abstract: A photo-setting resin is shaped into a three-dimensional resin model by scanning successive resin solution layers of a photo-setting resin solution with a radiation beam to form a stack of scanned set layers of photo-setting resin, each of the successive resin solution layers having a shaped region of an isometric section. The radiation beam is scanned along a contour line of the shaped region to set the shaped region along the contour line, and scanned in a raster scanning mode to set the shaped region inwardly of the contour line. Specifically, the radiation beam is scanned along a first line which is spaced a first distance inwardly from the contour line thereby to set the shaped region along the first line, and the radiation beam is scanned inwardly of a second line which is spaced a second distance inwardly from the contour line thereby to set the shaped region inwardly of the second line. The first distance is smaller than the second distance.

  • Patent number: 5432045
    Abstract: A photo-solidification modeling apparatus and a photo-solidification modeling method, wherein the reliability of an operation for coating the upper surface of a solidified layer with an unsolidified liquid is improved and the time required to carry out the same operation is reduced. To meet the purpose, a clearance is formed between the lower surface of a recoater travelling on a solidified layer and the upper surface of the solidified layer. When this condition is satisfied, an unsolidified liquid is introduced onto the solidified layer by virtue of both the force of the lower surface of the recoater which drags the unsolidified liquid and the nature of the unsolidified liquid entering the clearance. When recesses are provided in the lower surface of the recoater, the liquid adsorbed to the surfaces of the recesses is also introduced onto the unsolidified layer.

  • Patent number: 5284536
    Abstract: A method of fabricating model trees and plants for decorating a diorama. The model is made from stacking foliage disks on a telescoping dowel, which functions as an imitation trunk. First, an outline of leaves and branches is drawn within a panel on paper. Next, the outline is shaded in to obtain a silhouette thereof. Numerous foliage disks can be clustered on a single panel to conserve space and to facilitate mass production. The silhouette is photographed to obtain a reverse image. Then through photolithography and etching, a metal template of the reverse image is made. The template is overlaid on a wood veneer having a kraft paper backing, and is laser cut. After laser cutting, each foliage disk can be separated from the veneer sheet. An assembly hole is provided in each foliage disk to facilitate attachment to the dowel. In an alternative embodiment, the trunk can be fashioned from braided wire with one end that is unraveled and flared outwards.

  • Patent number: 5203944
    Abstract: A method for forming a three-dimensional article by thermal spraying utilizes a plurality of masks having a support layer with a removable liner thereon and a cut-away portion. The masks correspond to cross-sections normal to a centerline through the object. A set of masks defines all cross-sections through the object. A first mask is placed above a work surface and sprayed with a deposition material forming a first layer portion of the deposition material within the cut-out and second layer portion on the liner. The liner and second layer portion of deposition material thereon are removed. A second mask is placed over the remaining support portion of the first mask and sprayed with deposition material therein. Then the liner portion of the second mask and deposition material therein are removed. This process is repeated until the three dimensional article is formed. Then the mask support portions surrounding the article are removed from the article.
