  • Patent number: 5061527
    Abstract: Spray coating is performed utilizing a mixture of refractory material and a combustionable metal powder. The size of the particle of the metal in the mixture is selected so that the particle size is large enough to be treated safely and is small enough to be transported by means of a gas flow. As a carrier gas for carrying the mixture, a non-combustionable gas or fuel gas is used. A fuel gas and a combustion-assisting gas are discharged toward the section to be treated on the surface for directing a combustioning frame. The refractor material with the carrier gas is discharged into the frame established by the fuel gas and the combustion-assisting gas. The average size of the metal particle to be used in the spray coating is limited to be greater than 50 .mu.m. By enlarging the particle size of the metal, combustion of the metal particle becomes difficult. Combustion of such large particle size metal can be assisted by discharging the combustion-assisting gas together with the fuel gas.

  • Patent number: 5045342
    Abstract: A gloss control system is provided for controlling the surface gloss of a sheet material. The system provides separate and independent control of heat and moisture applied to the sheet material, rather than the fixed ratio of heat and moisture applied by previous steam shower systems. Heat may be applied by a plurality of infrared lamps whose radiation is directed to the sheet material surface. A plurality of upwardly facing atomizing spray nozzles act to provide streams of atomized water directed at the surface of the sheet material. A scanning gloss sensor detects the degree of surface gloss of the sheet material at various cross-directional locations and control the application of heat and moisture in accordance with the detected surface gloss to thereby achieve a desired gloss profile.

  • Patent number: 5045355
    Abstract: A carbon chalcogenide macromolecular composition prepared from carbon dichalcogenide and to a process for the preparation thereof. A carbon dichalcogenide, for example, carbon disulfide, in entrained in an inert gas, and the mixture formed therefrom is passed over a hot tungsten filament wherein carbon disulfide is degraded into fragments. The fragments are then deposited onto a surface of a nonreactive substrate. The deposited fragments recombine to form the macromolecular composition. A significant characteristic of the composition is its threshold voltage above which its electrical resistance drops precipitously. This characteristic also exhibits a unique temperature dependence. Dopants may be added to the composition to reduce the electrical resistance.

  • Patent number: 5029553
    Abstract: An apparatus for providing a uniform application of a functional coating to one or both sides of a moving metal strip includes an enclosed cabinet in which a corona discharge field is established between high voltage electrodes and the strip. The coating liquid and air are separately supplied under pressure to atomizing nozzles within the enclosure. The nozzles create a dense flat spray that is directed into the discharge field at an acute angle relative to the strip. The particles in the spray become charged and are attracted to the grounded strip, while those that are not charged are directed onto the strip by the force of the discharge field. The rate at which the coating liquid is supplied to the nozzles is varied in accordance with the speed of the strip to thereby obtain a uniform coating regardless of variations in strip speed or width.

  • Patent number: 5024864
    Abstract: Methods and apparatus are provided for applying a colorant material to the surface of a plastic insulation material which has been applied to an elongated material such as a metallic conductor (22) or an optical fiber which is being moved at any of a wide range of speeds along a path of travel. The coolant material is applied by nozzles which are staggered along the path of travel and which direct the colorant into engagement with the plastic insulation material at different radial directions. A first plurality of nozzles (46--46) each cause the colorant to be in a spray pattern (45) which is in the area of a plane. Advantageously, those nozzles cooperate to stabilize the conductor and prevent undulations thereof as the conductor is moved along its path of travel. A second plurality of nozzles (50--50) cause the colorant to be in a solid conical pattern (53).

  • Patent number: 5023116
    Abstract: Organic vapor and particulate matter resulting from spray painting in continuous painting lines are separately collected and disposed of in a closed painting system that permits access for touch up. The painting line typically includes an automatic painting booth, a touch up booth, a flash off tunnel, and a curing oven, and a conveyer that conveys objects to be painted through the line in that order. The automatic painting booth recirculates air through a filter and through the booth to maintain proper painting conditions, and is tightly closed except for the conveyer entrance. The touch up booth has an opening through which workers have access to the painted objects, and through which a makeup flow of air is drawn to prevent particulate and organic compounds from escaping. The make up airflows to the automatic painting booth. A portion of the flow of organic-laden air is withdrawn from the automatic painting booth to maintain the air within the booth at a safe organic concentration level, and burned.

  • Patent number: 5021265
    Abstract: A roll arrangement for the non-deforming treatment of moving web-type or strip-type products. The arrangement includes at least two rotatable rolls which are adjustable radially relative to each other. The arrangement is used, for example, for drying one or both surfaces of the product. The rolls are axially adjustable in opposite direction and each roll has slightly S-shaped or bottle-shaped contour over the entire length of the roll body, in such a way that the contours of two rolls arranged on both sides of a roll gap complement each other only in a certain relative axial position of these rolls. In other axial positions of the rolls, the roll gap becomes narrower either in the center or at the ends of the rolls, so that a uniform pressing action or other uniform non-deforming treatment of the product is possible over the entire width of the product independently of the bending of the rolls and/or deviations from the plane-parallelism of the surfaces of the product.
