Abstract:
A method for manufacturing a fire retardant cellulose insulation with reduced density and reduced settling. The method consists of adding a material, the fibers of which have a positive electrostatic charge, onto a shredded newspaper base either before or after the addition of a pre-coat, consisting of a mixture of limestone and an antistat. A fire retardant agent is then added and the materials are ground in a finish mill. The newspaper fibers become positioned at an angle to the paper pieces, increasing the distance between the paper pieces, thereby lowering the density of the cellulose. Fibers such as ground cardboard, wood mulch, sawdust, fiberglass fibers and polyester fibers are examples of materials with electrostatically positively charged fibers.
Abstract:
A process to coat granular through powdered material for particular bulk products that is cost-effective for bulk products and in which the coated product is produced continuously and in a quality and throughput that meets requirements for bulk products is provided. This is attained by the coating material being applied to the granular through powdered material particles in the form of a coating matrix that does not completely envelope the material particles with coating material, with the matrix then being dried and solidified by the process air, the coating material is applied continuously to the bed of material in a continuously operated fluidized bed in at least two different zones. The coating material is applied to the material particles located in the fluidized bed in the form of solutions, suspensions or melts with a solids fraction of 0.5 to 100%, preferably 2 to 20%. The coating materials are preferably inorganic salts, fats, waxes, celluloses, stearates, metals or metal compounds, and the temperature of the air fed to the fluidized bed for the coating area is dependent on the material, and is between null20null C. to null300null C. The end product is continuously discharged from the fluidized bed.
Abstract:
The invention concerns a method for collecting and encapsulating with a coating agent particles dispersed in a fluid at supercritical pressure and an installation for implementing said method. Said method is characterised in that it comprises steps which consist in: expanding said fluid at a pressure less than its critical pressure, so as to bring it to a gaseous state; causing said gas to trickle down in a liquid consisting of a solution substantially saturated with the coating agent in a solvent in which the particles are insoluble, so as to exact at least partially the solvent; and causing the coating agent to precipitate onto the particles thereby forming microcapsules.
Abstract:
A process for mechanical plating zinc alloys onto metal substrates is disclosed. The process is particularly suited to plating zinc-aluminium or zinc-manganese alloys onto aluminium or magnesium substrates. The zinc alloy particles are immersion coated with tin prior to plating upon the metal substrate. Fluoride ions are preferably added to the plating media to increase plating efficiency, particularly when zinc aluminium alloys are being plated.
Abstract:
A conductive paste having a desired viscosity which does not change with time, and having stable viscosity characteristics, and an electronic component formed using the conductive paste are provided, the conductive paste including a conductive powder, an organic vehicle, at least one compound selected from the group consisting of a compound which has a tertiary amine structure and which is dissolved into the organic vehicle, and a compound which has a heterocyclic structure including nitrogen but not including sulfur and which is dissolved into the organic vehicle.
Abstract:
A manufacturing process of Christmas tree decorations where glass half-products are first blown to required dimensions and shapes, including the process stem. This glass half-product is fixed into the rack and placed into the metal-coating device where, under vacuum conditions, a thin (1 to 7 microns) layer of metals and/or their alloys is coated on its surface by vacuum plating or vacuum powder coating processes. The metal-coated surfaces created this way may be finished in various colors using clear and color varnishes either gloss or matt. The glass half-products for Christmas tree decorations may be provided with shading in the place of intended decor before the half-product is put into the vacuum metal-coating device. After the shading elements are removed, clear non-coated spots are created on the decoration surfaces. The rack accommodating the glass half-products of decorations is for their placement into the metal-coating device when above methods are performed.
Abstract:
A coating with a low coefficient of friction on a body, with at least its coated surface zones containing polymers, is provided. A method for producing the coating is provided. The coating acts as a lubricant for a body of this type. The coating, being bonded to the surface of the body at least by intermolecular forces and having LC properties, is provided. The method for producing a coating of this type, in which compounds having at least one mesogenic group are produced, and in which a plurality of components are bonded, at least in some areas, to the surface of a body of this type either directly or via the primary chain of a polymer, is also provided.

Methods of coating particles with nanometer to multiple nanometer thick coatings in atmospheric pressure, and using pneumatic fluidization, are also provided.
Abstract:
Disclosed is an image forming method comprising the steps of: providing a print output by a nonsilver photographic color hard copy recording system; providing a protective layer transfer sheet comprising a thermally transferable protective layer having a single or multi-layer structure separably provided on a substrate sheet; putting the print and the protective layer transfer sheet on top of each other and thermally transferring the protective layer onto an image in the print so as to cover at least the printed portion in the print; and separating the substrate sheet from the protective layer transfer sheet.
Abstract:
Apparatus and method for applying liquid coating to pellets in a flowing feed stream are provided. An incoming bulk material feed is conditioned to produce a ribbon-like agglomerated flow pattern, and the bulk material is passed through a first spray section which coats an exposed surface of the pellets flowing therethrough. The flow direction is reversed in a second spray station, which operates to expose an opposite surface of the pellets, such that the second spray section coats substantially the remainder of the outer surface of the pellets.
