  • Publication number: 20210162704
    Abstract: Fabricate a panel (5) by building a sacrificial relief (10) by an additive process of multilayer deposition, applying a facade layer (20,30) over the sacrificial relief so as to conform to the contour of the sacrificial relief, depositing a foamable composition (40, 50, 60) over the facade layer.

  • Patent number: 6255363
    Abstract: An organosol comprising a high molecular weight (co)polymeric steric stabilizer covalently bonded to an insoluble, high molecular weight thermoplastic (co)polymeric core is described which has the ability to form a three dimensional gel of controlled rigidity. The gel provides improved liquid ink or liquid electrophotographic/electrographic toner compositions by increasing sedimentation stability of the colorant, without compromising print quality or ink transfer performance. The gel is formed by manipulating the solubility parameter difference between the stabilizer and the solvent to achieve optimum performance of the dispersion.

  • Patent number: 6103781
    Abstract: A liquid ink composition containing organosols having side-chain or main-chain crystallizable polymeric moieties is described. The incorporation of organosols having crystallizable polymeric moieties into the ink compositions provide improved blocking resistance and improved erasure resistance when used in ink transfer, ionographic, electrographic and electrophotographic color printing or proofing processes.

  • Patent number: 5737674
    Abstract: A vapor control system and an electrophotographic system having a vapor control system for reducing vapor emissions. A vapor collection mechanism collects at least some of the vaporized carrier which is then transmitted to a container having a vapor inlet and a vapor outlet containing a cooling liquid, the cooling liquid having a temperature less than the temperature of the vaporized carrier but greater than zero degrees Centigrade. A vapor inlet located at a point below the surface of the cooling liquid results in the vaporized liquid bubbling through the cooling liquid and being condensed therein. The cooling liquid is immiscible with water and, preferably is the carrier liquid. Mechanical resistance devices promote increased bubble residence time and smaller bubble size.
