Abstract:
A method of providing a substrate with a decorative coating simulating the appearance of grained wood. A continuous layer comprising an aqueous medium which contains a polymeric binder and a particulate, non film-forming material is applied to an opaque surface of the substrate (the particulate material and the resulting layer both being lighter in color than the opaque surface. While the layer remains in the liquid state, a tool having a longitudinal extending face which has a convex section transverse to the longitudinal direction thereof, is drawn along the layer, the face of the tool having a series of spaced ridges along the longitudinal direction. The tool is rocked about the face as the tool is drawn along the layer, so as to discontinuously remove parts of the layer and selectively expose part of the underlying surface and to produce a decorative appearance resembling heart grains of cut timber.
Abstract:
A method of printing using dry pigments is introduced, wherein a binder material is applied to the surface of an object uniformly or in a pattern, and then dry pigment is applied to the binder material in a pattern or uniformly. The dry pigment sticks to the patterned binder, or the patterned pigment may be bound to the uniform binder, to produce a pattern.
Abstract:
A method for producing a, in particular thin-walled, pipe conduit element with a surface structure reinforcing the pipe conduit element is proposed wherein the pipe conduit element continuously passes by at least one embossing element guided about the periphery of the jacket thereof and the surface structure is embossed onto the jacket of the pipe conduit element by the embossing element using pure mechanical pressure. For embossing the surface structure onto the pipe conduit element, an arrangement of preferably several embossing elements, in particular balls or rollers are used which are distributed about the periphery of the pipe conduit element jacket. The invention also concerns a device for producing a surface structured pipe conduit element using a guidance having embossing elements and which can be rotated about the periphery of the jacket of a pipe conduit element continuously supplied to the device.
Abstract:
This invention features a method of labeling objects for anti-counterfeit purpose, especially refers to a method employing ribonucleic acid for product anti-counterfeit labeling and authenticity verification by PCR method. The procedure involves label objects with medium which contains ribonucleic acid. For verification of authenticity, the medium is removed and extracted for ribonucleic acid which is then amplified by PCR method for comparison.
Abstract:
A method for painting a panel using a paint applicator defines a painting pattern with a plurality of points on a surface of a panel to be painted, the pattern extending in a predetermined direction and the points defining opposite edges of the pattern extending in a predetermined direction, with at least one edge of the pattern being adjacent an edge of the panel. The applicator is moved relative to the panel to apply the paint in the painting pattern having a desired film thickness. The pattern including a first plurality of pattern segments and a second plurality of reinforcing segments, the pattern segments being connected together each extending between an associated pair of the points on the opposite edges of the pattern, and the reinforcing segments each extending between an associated pair of the points adjacent the edge of the panel. A plurality of different painting patterns can be stored in a memory for selecting the one pattern to be used.
Abstract:
Aqueous electroplating solutions and methods are provided for the codeposition of zinc and chromium. The solutions include effective amounts of zinc, chromium, and hydroxyl ions. The solutions further include an effective amount of one or more ions of alkali metals, alkaline earth metals, or a combination thereof other than sodium and potassium, to in major part balance the hydroxyl ions. A preferred alkali metal is rubidium.
Abstract:
A method for making laboratory containers includes designating an area for the container label, applying a ceramic base coating material in that area, the coating and the container having a very similar coefficient of thermal expansion, and then etching the label area with a laser.
Abstract:
The present invention is a method and system of marking data media products by introducing a predetermined tracing substance constituting a security marking into a polycarbonate (or polystyrene) composition during the manufacturing stages of the polycarbonate material into a data media, such as a compact disc (CD) or digital versatile disc (DVD). This marking technique is useful in tracking pirated data and/or sources, such as CDs or DVDs, to thereby prevent future pirating of data. Using mass spectrometry, specific types and/or quantities of isotopes of each tracing substance, on a structural level, are used to indicate a specific marking and product identity characteristics, such as a specific lot number, batch number, manufacturer identity, shipping date and the like. The security marking is preferably invisible to the naked eye. The security marking technique is also useful for tracking, authenticating and quality control purposes.
Abstract:
To provide a method capable of producing a separator integrated with a gas flow channel of fuel cells efficiently at low costs without deteriorating processing accuracy and the like. A plane-facing electrode nozzle 30 is placed oppositely to the face to be processed, which is partially covered with a mask M, of base material B of a separator. Under the condition of feeding electricity to the electrode nozzle 30 and the base material B of a separator, an electrolytic solution is injected and fed from the side of the electrode nozzle 30 to the face to be processed of the base material B from a direction that is almost perpendicular to the face. Thereby, the unmasked portion undergoes electrolytic etching with the electrolytic solution lying between the face to be processed and the electrode nozzle 30 to form recessed portions for making a gas flow channel.
Abstract:
This invention describes methods of synthesis and applications of planarized photonic crystals. Provided are simple, quick, reproducible and inexpensive methods that combine self-assembly and lithography to achieve the first examples of vectorial control of thickness, structure, area, topology, orientation and registry of colloidal crystals that have been patterned in substrates for use in lab-on-chip and photonic chip technologies. 1-, 2 and 3-D colloidal crystals patterned either on or within substrates can be used for templating inverted colloidal crystal replica patterns made of materials like silicon as well as building micron scale structural defects in such colloidal crystals. These photonic crystals can form the basis of a range of optical devices that may be integrated within photonic chips and coupled to optical fibers and/or waveguides to enable development of highly compact planarized optically integrated photonic crystal devices and circuits for use in future all-optical computers and optical telecommunication systems.
