|20120247693||STRUCTURAL ASSEMBLY WITH A TIED, FLEXURALLY DEFORMED PANEL - An assembly includes a flexurally deformed panel, which is connected to a membrane tie by a linear connector and is tied by the membrane tie to form a geometrically stable pre-stressed structure. More than one panel may be flexurally deformed and tied together in an assembly and more than one membrane tie may be present within an assembly. Panels are typically semi-rigid sheet materials, for example metal sheets, plastic sheets, or sheets of composite materials, such as glass or carbon fibre reinforced plastics or resins. Membrane tie members are typically flexible, for example plastic films, fabrics or nets or arrays of rods or cables. The assemblies have many different geometric forms and many different practical applications. Assemblies may be relatively large, for example demountable and reusable shelters or flat-pack point-of-purchase display assemblies, or may be relatively small, for example a photograph or postcard display system.||10-04-2012|
|20120145017||PRINTING LAYERS OF CERAMIC INK IN SUBSTANTIALLY EXACT REGISTRATION DIFFERENTIAL INK MEDIUM THERMAL EXPULSION - A method of partially imaging a substrate, for example glass, with a print pattern comprising layers of ceramic ink in substantially exact registration. The method relies on a mask ink layer defining the print pattern and differential thermal expulsion of ceramic ink medium during a heat fusing process between the areas outside the print pattern and within the print pattern. This results in pigment and glass frit forming a durable image material adhered to the substrate within the print pattern and non durable material outside the print pattern, enabling its removal outside the print pattern to leave the desired layers of ceramic ink within the print pattern in substantially exact registration.||06-14-2012|
|20100181020||VISION CONTROL PANEL ASSEMBLY WITH A CONTRASTING COLORED LINER - An assembly includes a light-permeable film layer, a release liner, and a print pattern. The print pattern includes a base layer. The print pattern sub-divides the film layer into a plurality of discrete base layer areas and/or a plurality of transparent areas. The base layer includes a design imaging surface of a first color. The release liner includes an imperforate material. The release liner includes a release surface. The imperforate material when viewed through said light permeable film layer is a second color contrasting with said first color by the graytone of said second color differing from the graytone of said first color by at least 10%. This contrast may provide a more realistic perception of how the assembly will look in situ (e.g., on a window).||07-22-2010|
|20100134542||INKJET PRINTING PARTIALLY IMAGED PANELS WITH SUPERIMPOSED LAYERS - A panel and method for making the panel are disclosed. The panel includes a substrate sheet partially imaged with a print pattern. The print pattern subdivides the panel into a plurality of discrete printed areas and/or a plurality of discrete unprinted areas. The design is superimposed on or forms a part of said print pattern. The design comprises a design layer. The print pattern includes a base layer. The print pattern includes elongate printed areas orientated lengthways in one direction. The design layer and base layer include inkjet printable ink in elongate ink deposits orientated lengthways in the one direction. The elongate ink deposits may have an aspect ratio of length:width greater than 1.5:1. The base layer may include white ink. The panel may be made using a digital inkjet cylindrical printer that prints the base layer during at least 10 revolutions of the cylinder.||06-03-2010|
|20100112223||PRINTING SUPERIMPOSED LAYERS - An apparatus and method for making a panel with superimposed layers of marking material in substantially exact registration is provided. An assembly includes a stencil layer sandwiched between a substrate and a transparent coating. The stencil includes a release surface. The coating tends to secure the stencil layer to the substrate, e.g., for storage and/or transport, and may protect the stencil layer from marking materials that might otherwise penetrate the stencil layer. A design and background layers are then printed onto the coating. A force is then applied to remove the background layer, design layer, and coating that are disposed on the stencil layer, leaving the remainder of the background layer, design layer, and coating adhered to the substrate in substantially exact registration within portions of the substrate that are devoid of the stencil layer. The design layer is right-reading visible through the substrates.||05-06-2010|
|20100107459||ALTERNATING SIGN - An alternating sign assembly includes a sheet of light permeable material comprising a front surface and a rear surface; a front design that includes a front design layer; a silhouette pattern including light-restricting imaging material, said front design being superimposed on or forming a part of the silhouette pattern, said silhouette pattern subdividing said sheet into a plurality of discrete areas of said imaging material and/or a plurality of discrete areas devoid of said imaging material; a switchable front source of artificial illumination of said front design; a rear design disposed rearwardly of the front design; and a switchable rear source of artificial illumination of said rear design. The sources of illumination may be alternately turned on to make the front and rear designs alternately visible to an observer in front of the assembly.||05-06-2010|
