Abstract: In-line flat-rolled steel cleansing and finishing methods and apparatus are disclosed which enable flat-rolled steel, as supplied with surface areas contaminated with iron fines and other debris from gauge reduction operations, to be continuously processed in-line, free of interruptions for cleansing purposes. Continuous-strip methods and apparatus are disclosed which enable in-line continuous-strip cleansing in a manner which decreases iron fines carried by strip surfaces to a desired level while providing for continuous uniform cleansing. Carry-over of iron fines from the cleansing operations so decreases such that iron content of a coating means is decreased resulting in improved corrosion-protection coating. Diminishing iron content in a hot-dip galvanizing bath increases efficiency of aluminum additions and diminishes iron-aluminum dross.

Abstract: In a regenerating method and apparatus of a recorded material in which at least a portion of the recorded material in the vicinity of a surface thereof on an image forming side is wet and expands with a liquid, the wet and expanding liquid (also called an image removing accelerating liquid in the following description) is provided to the recorded material so that the portion of the recorded material in the vicinity of the surface thereof is wet and expands with this liquid.

An image in the vicinity of the surface of the recorded material is transferred onto the separating member so that the image forming substance on the recorded material is removed therefrom.

Abstract: A process for removing scale from stainless steel using an aqueous solution containing hydrogen peroxide and an inorganic acid, i.e., hydrochloric or sulfuric acid. A hot rolled or annealed stainless steel strip (10) covered with scale is immersed into hot inorganic acid contained within pickling tanks (12) and (14). Thereafter, the strip may have residual amounts of tightly adherent scale (11). This scale is activated by a solution containing the inorganic acid and hydrogen peroxide applied to the strip such as by a spray header (16) extending completely transversely across and positioned above the strip and another spray header (18) extending completely transversely across and positioned below the strip. It may be desirable to pass the activated strip through the hot inorganic acid again and reactivate the strip at very high line speeds to insure complete removal of scale from the strip. Any hydrogen peroxide spray dripping from the strip is collected on a catch pan (30) and flowed into a tank (28).

In addition the invention is directed to a device for implementation of the process, characterized by, in particular, several processing stations such as venturi modules being provided in the treatment chamber which cause an increase in the shearing force between the strip and the treatment liquid.

Abstract: Method for removal of a liquid edge bead from the side marginal edges of a moving web, such as a strip. The method involves providing a moving web and two pair of manifolds, which are positioned above and below the top and bottom surfaces of the web, discharging a gas curtain approximately normal to the plane of the web, and introducing gas to the manifolds to produce a gas curtain from each manifold so that a portion of the gas curtains are deflected towards the edge of the web. The gas curtains that directly impact the web, in combination with a portion of the gas curtain that extends beyond the edge of the web and the portion that is created by the opposing gas curtain, create turbulence at the side marginal edges of the moving web to remove the liquid edge bead and to carry the liquid away from the marginal edges and the moving web.

Abstract: A process for removing scale from stainless steel using an aqueous solution containing hydrogen peroxide. A hot rolled or annealed stainless steel strip (10) covered with scale is immersed into hot sulfuric acid contained within tanks (12) and (14). Thereafter, the strip may have residual amounts of tightly adherent scale (11). This scale is activated by the aqueous solution containing hydrogen peroxide applied to the strip such as by a spray header (16) extending completely transversely across and positioned above the strip and another spray header (18) extending completely transversely across and positioned below the strip. Any peroxide spray dripping from the, strip is collected on a catch pan (30) and flowed into a tank (28). Preferably, the peroxide solution is a dilute concentration of the acid in tanks (12) and (14). The hydrochloric acid removes smut from the strip formed by the sulfuric acid to improve the cleanliness of the pickled strip.

Abstract: A method and a device for cleaning and exposing portions of limited length of strands of steel wire which are surrounded by a corrosion protection substance, particularly grease, wherein the strands of steel wire and the corrosion protection substance are enclosed by a sheathing of synthetic material.

Subsequently, a flushing pipe is connected to the sheathing at the end of the strand and the strand is cleaned by admitting a flushing liquid under high pressure into the space surrounded by the sheathing, so that the corrosion protection substance and the flushing liquid emerge at the opening. Finally, the sheathing is removed entirely from the strand by pulling off the sheathing.

Abstract: An ablating gelatin pig for use in tubulars which can easily negotiate the bends, etc in a tubular. Due to the properties of gelatin, the pig will ablate thereby depositing a protective layer onto the wall of the tubular. The pig can be molded outside the tubular or it can be formed in situ. The pig is formed by mixing common gelatin with a heated liquid and then allowing the mixture to cool to ambient temperature. Preferably, the liquid includes a treating solution (e.g. corrosion inhibitor, drag reducer, etc ) which is to be used to treat the pipeline. In some applications, a slug of the treating solution is also passed through the pipeline between two ablating gelatin pigs. For high temperatures applications, a hardener may be added to the pig to increase the melting temperature of the pig and/or a slug of the hardener can also be passed through the pipeline between two ablating gelatin pigs if necessary.
