Abstract: An apparatus for applying an adhesive pattern to a chip mounting surface by means of an adhesive dispensing head movable in z, y, and z dimensions, contains a first carriage, which is movable in x and y dimensions using first and second actuators. A second carriage with a dispensing head is movable in the z dimension, perpendicular to the chip mounting surface, on a guide mounted on the first carriage. A third actuator is provided with a positioning motor mounted in a stationary manner and an auxiliary carriage displaceable in the z direction. The auxiliary carriage, driven by the positioning motor, runs in a stationary guide. The auxiliary carriage has a positioning surface parallel to the chip mounting surface and a stop, the stop kept in constant contact with the positioning surface. Preferably, this contact is a gliding contact retained by a spring. The apparatus has good dynamic properties which make possible a rapid "drawing" of adhesive patterns with a high degree of precision.

Abstract: A method for treating magnesium die castings sufficiently cleans the die castings and improves their paint adhesion and corrosion resistance by utilizing hydroxy acetic acid, among other constituents. The method includes cleaning the castings with an alkaline cleaning solution, rinsing with water, pickling the castings with an aqueous hydroxy acetic acid solution, rinsing with water again, and then contacting the castings with a chrome-free pretreatment. The alkaline cleaning and pickling steps appear to remove substantially all die casting impurities in order to adequately prepare the metal for application of the pretreatment. The chrome-free pretreatment may be an organofunctional silane solution or an aqueous polymeric system having hydroxyl and carboxylic functional groups along with a compound of a group IV-B element. The pretreatment is then painted or contacted with another decorative coating, with no rinsing step occurring between the pretreatment and painting steps.

Abstract: A method and an industrial robotic device for uniformly applying coatings at appropriate thickness and pitch upon a surface moves a spray applicator foam dispenser between two parallel tracks.

Abstract: A spinning rotor (1) with a spinning cup (2) has an interior surface coated with a nickel dispersion layer (6) of an essentially even layer thickness having a concentration of hard material grains (7) embedded therein which is clearly less at the surface of the fiber slide face (9) than in the rotor groove. The coating is produced by bathing the spinning cup in a nickel dispersion bath during the final stage of which the concentration of the hard material grains in the bath is reduced at least in the bathing area, while the spinning cup is moved in this bath and rotated around its longitudinal axis while maintaining the spinning cup in a spatial orientation relative to the bath wherein an imaginary plane passing through the rotor groove is at least approximately perpendicular to the surface of the nickel dispersion bath.

Abstract: A method for bonding a resin which has a high glass transition temperature but low affinity to copper surfaces with a copper surface with sufficient adhesive strength. The method comprises coating the copper surfaces with an aqueous solution containing at least 0.05% of aminotetrazole or an aminotetrazole derivative, or an aqueous solution containing at least 0.05% of aminotetrazole or an aminotetrazole derivative and at least 0.1% of aminotriazole or an aminotriazole derivative.

Abstract: A method and apparatus for coating a moving web of paper of paper-board. In the method, the web to be coated is passed to a coater station, wherein a coat layer is applied to at least one surface of the web, and the web is dried at least to some degree and passed to the next treatment step. The coat is applied by spraying the coating mix on the web surface by a high-pressure spraying nozzles, the pattern width covered by a single nozzle is essentially narrower than the cross-machine width of the web being coated.

Abstract: Method comprising a thermal treatment step proper during which said sheets are in contact with a part of their surface (that is they are, for example, coiled or in tight packets) and a step of preliminary treatment of these surfaces by means of an aqueous solution or a water-alcohol solution into which an organic product of the silane type has been introduced.This treatment makes it possible to prevent the sticking of the sheets; it is particularly effective and it does not require any preliminary activation of the surface.

Abstract: A two-part coating system comprises a first part comprising a blend of an aliphatic polyisocyanate with a non-reactive resin or a liquid epoxide resin and a second part comprising an aromatic polyamine, such that the two parts when mixed together and applied to a surface form a rapid-setting impervious coating. The coating system is suitable for application by spraying using equipment in which the two parts of the system are first combined at the point of spraying, at the spray head. In particular the system may be used to apply an impermeable lining to the internal surfaces of pipelines, for example by means of a centrifugal spinning head.

Abstract: A sampler containing a sample material applied to a substrate with a cover over the sample material. Sample material is deposited on the substrate by spray depositing the sample material on the substrate, which causes the sample material particles to lie in a substantially flat orientation. To enable the spraying of a material, a slurry is formed by mixing the sample material with a suitable carrier. The carrier then evaporates, leaving the sample material on the substrate.

Abstract: A radiator hose is provided with an inner tube rubber and a cover rubber. The inner tube rubber is coiled on the outer circumference with filament yarns made of nylon 6,6 separating predetermined spaces each other. The filament yarns are twisted at predetermined twist number before coiling, and pass through an adhesive agent supplying step, a dry-heating step while applying tension to the filament yarns and reel-hank steps, and goes into a wet-heating step. For the wet-heating step, the filament yarns are given temperature equivalent to a vulcanizing temperature, applying no tension to the filament yarns. By the wet- and dry-heating, the filament yarns are prevented from biting into the inner tube rubber. Since the filament yarns are immersed into the solution of an adhesive agent before the dry-heating, the solution attached on the filament yarns is dried off rapidly by the dry-heating thereafter.
