Abstract: The coating device features a first applicator which, to begin with, forces coating substance applied on the shell of a web roll (1), in a press gap formed between said roll and a press roll (2), into the web (W), thereby impregnating it. This makes it possible to apply with maximum uniformity and without web breaks and wrinkles, immediately successively, a second coating layer during the still wet condition of the first layer where, naturally, again a web guide roll (3) is provided.

Abstract: In a coating, line a first substrate such as a vehicle body, made of a steel plate, is coated separately from a second substrate made of a different material including a plastic, such as vehicle parts, i.e., bumpers and so on, and the parts are assembled with the vehicle body. The vehicle body and parts are coated separately to form each a highly reflective surface coating. The coating is implemented by a spraying step for spraying the paint on them to form a coat; and a drying step for drying the coat. The paint is sprayed in the spraying step in a film thickness which is thicker than a thickness at which the paint sags on a surface extending at least upwardly and downwardly.

Abstract: A nozzle, nozzle assembly and method for internally coating containers uses a dual orifice nozzle and method to direct divergent spray patterns at separate interior surface portions of the container where the coating liquid is most needed and to minimize misting, overspray and waste. The nozzle comprises a generally cylindrical body having a forward portion, a middle portion, a rear portion, a first conduit extending longitudinally therethrough terminating in a first opening disposed in the forward portion, and a second conduit extending longitudinally therethrough terminating in a second opening formed in the forward portion of the body. The first and second openings are oriented at an acute angle with respect to a central longitudinal axis of the nozzle to direct the separate sprays of coating liquid from the body generally in separate patterns diverging from the central longitudinal axis of the nozzle.

Abstract: The invention is a method of perfusing a material, such as wood, with a chemical composition that is insoluble in a given first fluid under supercritical conditions. A cosolvent is mixed with the first solvent to provide adequate solubility at supercritical conditions for the chemical composition. The method is useful for uniformly impregnating otherwise difficulty permeable materials. Impregnation of lumber or structural timbers with a preservative would be a typical use of the method.

The invention also relates to a method of operating the assembly and having features providing inter alia for movement of the distributor head relative to the carrier members in order to improve the distributor of liquid over the top surface of the carrier.

Abstract: A coating line contains a water paint coating step for forming a coat by coating a substrate with a water paint; a pre-heating step for pre-heating the coat; and a baking step for drying the coat by baking. In the coating line, the substrate coated with an oil base solid paint is further coated with the oil base solid paint in the water paint coating step. The substrate is then transferred to the next step by bypassing the pre-heating step or by passing through the pre-heating step which is not heated by turning a pre-heating device disposed therein OFF. The coating line may be provided with an oil base clear paint coating step to thereby form an oil base clear paint coat yielding a two-layer coat. By coating the oil base solid paint in the clear paint coating step only, a one-layer coat can be given.In the clear paint coating step, an oil paint can be coated in the coating line which is provided with a second pre-heating step subsequent to the clear paint coating step yet prior to the baking step.

Abstract: A focused ion beam is irradiated on a predetermined area of a substrate on which a film is to be formed, and a vapor stream of film-forming depositable material is directed onto a localized area of the substrate which is being irradiated with the focused ion beam to convert the film-forming material to a film deposit on the predetermined area of the substrate. The process can be used to repair white-spot defects in masks and to otherwise deposit films having sharply defined edges and widths in the submicron range.
