Abstract:
A printing medium in cylindrical form consists of a dimensionally stable solid, partly hollow or hollow cylinder and a photopolymerizable crosslinkable cylinder layer which is applied in particular in part-layers by means of a coaxial coating apparatus and on which an IR radiation-sensitive layer is applied, preferably as a single layer, by means of a coaxial coating apparatus. The result is an economically produced printing medium having uniform layer formations and layer thicknesses and the advantage of simple imagewise exposure and development and rapid use in the printing press.
Abstract:
The purpose of the invention is a coating precursor comprising a silicone resin, a mineral filler and an organic solvent capable of dissolving the said resin and putting the said mineral filler into suspension, the said silicone resin and the said mineral filler being capable of chemically reacting so as to produce a solid layer on a substrate after the organic solvent has evaporated and a cohesive refractory layer after a calcination operation. Another purpose of the invention is a method for coating a given surface of a substrate with at least one refractory layer containing silicon in which the substrate is coated with a coating precursor according to the invention so as to form a green layer and a heat treatment is carried out to calcine the said green layer and to form a cohesive refractory layer. The invention is a means of obtaining a protective coating capable of resisting oxidising environments, liquid metal and solid or molten salt.
Abstract:
A method of applying a heat-rejection coating directly on a substrate of a metallic component is disclosed. The steps include supplying a metallic component, such as of a gas turbine engine, before applying a reflective-coating mixture onto the component, wherein the reflective-coating mixture comprises a metallic pigment and a reflective-coating-mixture carrier, and wherein the step of applying is accomplished by a method selected from the group consisting of air-assisted spraying, airless spraying, brushing, and decal transfer. The component having the reflective-coating mixture thereon is fired to form a reflective coating on the component.
Abstract:
Disclosed are carrying method and a carrying apparatus capable of carrying a flexible member to be carried in a way that flattens it. Further disclosed are a coating method of uniformly stably coating the thus flattened flexible member as a flexible support member with a coating liquid and a manufacturing method of manufacturing a coating material having uniform coating layer thickness by this coating method. In the carrying method and the carrying apparatus, a web is corrugated by deforming the web in a widthwise direction, a first guide roll disposed downstream thereof stretches the corrugation and thus corrects the web, thereby carrying the web in a flattened state. In the coating method and the coating material manufacturing method, downstream of the first guide roll, the corrugation is corrected, and the flat web is coated with a coating liquid.
Abstract:
A method and an apparatus for forming a coating of a paint composition on a moveable substrate is disclosed. The method involves determining the volume flow rate of the paint composition that is required to form a desired wet film thickness for a given substrate speed and coating width and supplying the paint composition to a pool in the nip between an applicator roll and a metering roll or other suitable metering means at a flow rate that is substantially equal to the calculated flow rate, and then monitoring the level of the paint composition in the pool and adjusting operating parameters, such as the pressure between the rolls to maintain the paint composition level substantially constant. Maintaining a substantially constant level of the paint composition in the pool in a situation where the volume flow rate of the paint composition into the pool is substantially equal to that required to form the desired wet paint thickness on the substrate ensures that the required volume flow rate of the paint composition is being transferred from the pool to the substrate.
Abstract:
The present invention relates to compositions for treating shoes, especially leather-containing shoes, such as athletic shoes, and methods and articles of manufacture employing same to treat the shoes prior to and/or during and/or after washing the shoes. More particularly, the present invention relates to compositions applied to one or more shoes in need of treatment prior to and/or during and/or after washing the shoes for imparting a desired benefit to the shoes such as cleaning and/or conditioning and/or disinfecting and/or deodorizing.
Abstract:
The present invention relates to a system and method suitable for automatic cleaning of a coating or extrusion head of a coating apparatus. The invention includes a scrubbing station wherein a combination of physical contact and strong solvent solution combine to remove coating fluid from the exterior of an extrusion head. A second cleaning station, preferably a rinsing station then further cleans the head of coating fluid and removes solvent used at a first cleaning station. The solvent used at the rinsing station is preferably self-drying thereby obviating the need for any further cleaning action. The invention also provides for the ability to prime the coating bead at the extrusion head so as to have a fully formed bead ready before the head begins coating a substrate, thereby providing an even coating across said substrate. The priming operation preferably comprises holding the head steady over a rotating priming roller while extruding fluid preferably at a constant volumetric flow rate. The extrusion head is removed from the priming station when the coating bead is properly formed, and the extruded coating material is dissolved in a solvent bath at the priming station. The priming operation may also be performed at either of the cleaning stations.
Abstract:
A coating layer, which has the property of releasing a coated liquid, is formed on the outer peripheral surface of a cylindrical rod. The rod is engaged with a first roll, and rotates in a predetermined direction. A coating liquid is supplied to a nip surface portion between the first roll and the rod in the predetermined direction, and a film of coating liquid is formed on the outer peripheral surface of the first roll. After the thickness of the coating-liquid film is adjusted at the nip surface portion, the thickness-adjusted film is transferred from the first roll onto a surface of the base paper directly, or indirectly through the second roll.
Abstract:
A coating apparatus for applying a coating liquid to a printing substrate. The coating apparatus has a rotatable first roll and a rotatable second roll, each having a surface energy. The second roll is positioned adjacent to the first roll and defines with the first roll a first nip through which the printing substrate passes A metering device is provided for applying a substantially uniform layer of coating liquid onto the second roll. The second roll in turn transfers the coating liquid to the printing substrate. The surface energy of the second roll is greater than the surface energy of the coating liquid. In one embodiment, the metering device includes a rotatable third roll and a doctor blade contacting the third roll, each having a surface energy. The surface energy of at least a portion of either or both the third roll and doctor blade is less than the surface energy of the coating liquid.
Abstract:
Continuous void-free uniform coatings are formed on filamentous articles by applying a voided or otherwise substantially uneven coating to at least some of the exposed portion of a filamentous article or to a rotating substrate. The filamentous article or substrate is passed through an improvement station containing a plurality of coating-wetted rolls that contact and re-contact the wet coating at different positions along the length of the filamentous article or rotating substrate, wherein the periods of the rolls improve the uniformity of the coating. For coatings applied to a rotating substrate, the uniform wet coating is transferred to the filamentous article. The final coating can be very thin, very uniform and completely or substantially void-free. The coating improvement can be quickly and easily obtained using low cost equipment.
