Abstract: The fluid jet applicator of the present invention utilizes a piezoelectric crystal to artificially stimulate the fluid supply chamber with coherent acoustic energy to pruposely generate and exploit the acoustic standing waves therein. As a result, although sized droplets will be formed at substantially the same frequency from each orifice, individual droplets will be formed so as to be out of phase with its adjacent neighbors in accordance with the standing acoustic wave pattern. By selecting only a very short print time, e.g., such that only one or two drops are formed within such a time and by controlling the frequency of such print time, a wide range of aesthetically appealing, unique, random interference of patterns can be created. Patterns closely simulating natural wood grains including knot holes can be readily produced by the present invention. More, the present invention allows patterns to be modified with relative ease and remarkable flexibility.

A shaft extends from the chamber through the passage and terminates, at a tip, at a location adjacent the first end of the passage. The shaft is positioned in the passage to provide a symmetric orifice between the passage and the shaft. The tip has a second surface flared outwardly at least 15 degrees from the longitudinal axis.

Abstract: A method of treating a body to produce a wood like appearance. A treating material is created by combining urethane mixtures aged different periods of time, from as little as one day up to five days, respectively. The combined mixture is allowed to flow into a water bath to create a line stream. The body to be treated is immersed in the water bath in the path of the line stream, removed and then dried. The treating material adhering to the body creates a wood-like appearance.

Abstract: Methods and apparatus are described for the random coloring of concrete roof tiles during the manufacture of such tiles. This enables the tiles to be installed in random fashion and without following any particular sequence. At the same time a roof is achieved which has an aesthetically pleasing random variation of the tile colors and which is absent the displeasing color patterns which often occur when tiles colored by a simple and frequently repeating pattern are not installed in proper sequence. Newly formed concrete tiles are sequentially advanced by a conveyor beneath a base applicator which sprays a base coat of coloring slurry over essentially the entire top surface of each tile. One or more overspray applicators located downstream from the base applicator then spray additional colors over different portions of the top surfaces of the tiles in intermittent, randomly varying fashion so that the color pattern on each tile is essentially unique and is not repeated on any other tile.

Abstract: The invention relates to a resinous polymer sheet material having surface decorative effects of contrasting gloss and to the method of making the same. The material is made by applying to a base a printing composition layer forming a pattern with designated areas containing a photoinitiator and then applying to said printing composition layer a resinous polymer wear layer having therein an actinic radiation curable polymerizable and cross-linkable monomeric materials. The composite thus produced is exposed to actinic radiation so that the areas above where the photoinitiators were applied are cross-linked. The product is then heated to form the composition. The resulting product has a lower gloss in such areas as compared to the remainder of the surface of the sheet.

Abstract: A method for producing a painting using a flotation process in which a floating elongate member is placed in a shallow pan of water and one or more oil based litho inks having different viscosities are placed on the surface of the water within the closed shape of the elongate member. Using an external force such as an air stream, the litho ink is formed into a desired pattern on the surface of the water and it is allowed to float undisturbed by external forces for a time lapse of about six to fourteen hours to form a textured pattern having finer and more textured paint globules than when the paint was first blown into a desired pattern. The paint pattern is lifted off of the surface of the water and onto a flexible sheet, and after the paint is at least partially dried, artists non-oil base ink is applied to the flexible sheet within the closed shape of the painting to areas of the sheet on which paint is not present.

Abstract: Production of a longitudinally striated coating on a strip article by advancing the article past an open side of an otherwise-enclosed trench so that the article surface to be coated closes the open trench side, while delivering concurrent laminar flows of two different liquid coating materials to the trench at least at one locality spaced from the trench open side, to keep the trench completely filled and to deposit a layer of coating material on the moving article surface. Liquid circulation in the trench caused by the motion of the article surface so distributes the two coating materials along the trench that the applied coating layer is constituted of alternating longitudinal striations of the two materials.

Abstract: In the coating of a major surface of a strip article, wherein the strip surface is advanced longitudinally past a dam and, immediately beyond the dam, past an extended wall spaced from the strip surface by a gap equal to a desired wet coating thickness, a first liquid coating material is applied to the strip surface ahead of the dam and a second liquid coating material is delivered under pressure to the gap beyond the dam through one or more apertures in the wall to produce a stripe or stripes of the second coating material. The apertures can be provided in a rotatable disk, constituting a portion of the wall; rotary movement of the disk angularly displaces the apertures so as to vary the location and spacing of the produced stripes, for example in a manner simulating the appearance of natural wood grain.

Abstract: In coating a support, such as a flexible web of synthetic organic polymer, with a coating composition comprising a film-forming material in an evaporable liquid vehicle, at least two of (1) the temperature of the atmosphere in the coating zone, (2) the temperature of the coating composition at the point where it is coated on the support, and (3) the temperature of the support at the point where the coating composition is applied thereto, are maintained at a temperature substantially equivalent to the equilibrium surface temperature of the coated layer within the coating zone. The equilibrium surface temperature is defined as the temperature assumed by the surface of a layer of the coating composition under steady state conditions of heat transfer following evaporative cooling of the layer in the coating zone. Such temperature control minimizes thermal gradients within the coated layer and significantly reduces the formation of mottle and similar coating defects.

Abstract: A fibrous building element such as a panel which can be used for roofs, soffits and walls. The fibrous element is coated on the side which will be positioned on the exterior of a building structure with a material which forms a crackled surface. The crackled surface permits water vapor or steam from the interior of the structure to pass through the panel. The crackled surface presents a surface-active hydrophobic agent to prevent rain, snow and moisture from penetrating the panel. The surface-active hydrophobic agent may be applied to the outer face of the crackled surface coating or may be mixed in the crackled surface coating.

Abstract: A method of enhancing the properties and appearance of polymeric substances is disclosed. The method involves treating a polymer so as to effect graft polymerization over the entire surface thereof in such a manner that variations in graft density occur across the surface of the polymer. This may be accomplished by forming chemically active species, e.g., ions or free radicals, in the polymer which vary in concentration across the surface of the latter and at least once contacting the surface of the polymer with a substance, for instance, a monomer such as a vinyl compound, which undergoes a graft polymerization reaction with the chemically active species. The chemically active species may be formed by irradiating the surface of the polymer with high energy radiation, for example, a beam of electrons. Different possibilities exist for achieving a varying concentration of the chemically active species across the surface of the polymer.
