Abstract:
A paint roller assembly is provided comprising a handle, first and second arms supported by the handle, a substantially cylindrical first paint roller rotatably supported by the first arm and a substantially cylindrical second roller rotatably supported by the second arm, whereby the two rollers are spaced from each other such that the first roller can rotate without contacting the second roller. Using this and similar paint roller assemblies, the painter can implement the method embodiment of the invention, by dipping only the first roller in a supply of paint and then contacting the wall with the first roller to apply paint to a region of the wall. The first roller is then removed from the wall and the painter rotates the assembly to position the second roller at the wall whereupon only the second roller is rolled over at least a portion of the region previously painted with the first roller. Thereafter, the painter withdraws the paint assembly from the wall, rotates the assembly and dips only the first roller in the supply of paint, whereupon the foregoing method steps are repeated for successively different regions of the wall.
Abstract:
A system and method using reporter elements provides retrospective identification of articles. An article is marked with reporter elements such that the mark has a characteristic spectral response when exposed to energy stimulation. To verify the authenticity of the article, a reader scans the mark containing the reporter elements and obtains a spectral signature. The reader then compares the detected signature to the characteristic signature to determine the authenticity or identity of the marked article.
Abstract:
A method of forming a metallic feature on a substrate, comprising the steps of: providing a stamp having a raised region; depositing catalytic particles on a selected area of the stamp, including the raised region thereof; providing a substrate; applying the stamp to the substrate, such that the raised region of the stamp causes a corresponding indented region in the substrate and at least some of the catalytic particles are transferred to a selected area of the substrate; and plating the selected area of the substrate.
Abstract:
A process and an installation for the production of a bituminous sealing sheet, comprises an armature impregnated and/or coated with a given bitumen and having a zone in the shape or a band or a portion of a band of a different bitumen from the first bitumen. An armature strip (2) is produced which is impregnated and/or coated except for at least one zone in the form of a strip or a strip portion (4) on at least one of its surfaces (2null, 2null), having a thinner thickness of bitumen (3, 3null) or no application of bitumen (3, 3null), to be used at the at least one strip or strip portion (4), over a controlled thickness, a different bitumen (5) from that initially applied and finally, after cooling and solidification of the eventually added bitumen (5), processing the resulting sheet or sealed membrane (11) in the desired form, the processing operations being carried out by continuous movement of the armature (2) in an installation (6) or suitable coating line comprising at least two coating stations (7, 7null, 8).
Abstract:
This invention pertains to the repair of parts comprising metals, and surfaces and coatings of these parts using reactive metals coating processes. Processes such as chemical vapor deposition (CVD), physical vapor deposition (PVD), plasma spray, and reactive coating (boronizing, carburizing, nitridizing, carbonitridizing, etc.) are known for producing durable coatings or surfaces on metal parts, and the present invention provides a means to spot-repair these coatings or surfaces without excessive buildup of repair material on undamaged areas.
Abstract:
The evaporative casting of molten metals has been shown to produce castings having smooth surfaces with significantly less signs of carbon deposits thereon by using expandable vinyl aromatic polymer particles containing a bromine-attached aliphatic or aromatic flame retardant and optionally, an organic peroxide.
Abstract:
A method for producing a painted ceramic body. A transfer material containing an inorganic pigment, or hot melt ink containing an inorganic pigment is directly or indirectly disposed on the surface of a ceramic body in an imagewise manner. Subsequently, the ceramic body with the image formed thereon is heated and the inorganic pigment contained in the image is sintered on the surface of the ceramic body.
Abstract:
A process for the incorporation of an antimicrobial agent into a fibre, fabric or piece goods is described comprising treating said material by passing said fibre into an aqueous liquor containing an antimicrobial agent selected from (a) halogeno-o-hydroxydiphenyl compounds; (b) phenol derivatives; (c) benzyl alcohols; (d) chlorohexidine and derivatives thereof; (e) C12-C14 alkylbetaines and C8-C18 fatty acid amidoalkylbetaines; (f) amphoteric surfactants; (g) trihalocarbanilides; (h) quaternary and polyquaternary compounds; and (i) thiazole compounds.
Abstract:
A faux finishing device including a paint roller having a core defined along a central axis. The core has an aperture therethrough that is aligned along the central axis. The device also has one or more roller bodies attached to the exterior surface of the core. Each body has an exterior surface that allows the device to create a random pattern when the body is coated with paint and placed in contact with a surface to be painted.
Abstract:
A method of treating a carbonaceous cell component of an electrolyte cell for the production of aluminum, to impart protection against deterioration during operation of the cell. A liquid suspension of a refractory material dispersed in a lignosulfonate binder solution is prepared and applied as a protective coating to the surface of carbonaceous cell components and allowed to dry.
