Abstract: The invention relates to a corrosion inhibitor for a metal material such as steel, of the type consisting of an aqueous solution containing an alkali metal nitrite, wherein said solution contains 0.01 to 0.3 mol/l of an alkali metal nitrite, 0.01 to 0.3 mol/l of an alkali metal phosphate, and phosphoric acid in a proportion of a quantity sufficient to maintain the pH of said solution, measured at ambient temperature, between 6.9 and 7.2.

Abstract: The process is characterized by the fact that, before drawing, a salt of the alkaline metal group formed by Li, Na, and K, and of an anion which is chemically inert with regard to the essential metal of the sheet chose from among the phosphates is deposited on the drawing tools. To deposit the salt, preferably, a solution of said salt is applied to the tools or to the sheet metal.

Abstract: The installation comprises a set of radial type cells (25a, 25b). The electrical supply of the strip (16) to be coated constituting the cathode is ensured by way of two electrically conducting deflector rollers (20) each mounted rotatably about an axle parallel to the axle of the drum (8) of the electrolysis cell. The deflector rollers (20) are arranged at least in part below the upper level of the drum (8) close to its outer surface. Two support rollers (21a, 21b) associated with each of the deflector rollers ensure the holding of the strip against the deflector roller over a substantial part of its periphery and as far as a zone close to the part of the outer surface of the drum (8) which is submerged in the electrolytic liquid (2). The invention applies in particular to the electrogalvanizing of a steel sheet.

Abstract: A system is provided for accurately positioning bales of fibrous material in relation to a mechanical means for transporting fibers from said bales to the hoppers of fiber feeders.

Abstract: For use with fiber feeding machines having a plurality of fiber bales arranged in two rows extending from each machine, and a fiber plucker device that moves along such bales to pluck fibers therefrom and transport the plucked fibers to such machines, a control system by which the fiber plucker device is selectively operable to pluck fibers from a predetermined number of bales in one bale row of each machine and to then automatically proceed directly to pluck fibers from a predetermined number of bales in the other bale row of such machine. A control system is also disclosed for causing the fiber plucker device to pluck fibers sequentially from both bale rows behind one or more of the fiber feeding machines, and to pluck fibers, alternatively, from only one of the two bale rows behind other fiber feeding machines. Additional control means are provided for selectively determining the number and combination of bales which are plucked from any row of bales by the fiber plucker device.

Abstract: A plurality of safety devices associated with apparatus for picking-up fibers from bales and delivering such fibers to a hopper or the like, such safety device acting to warn the operator of such apparatus of a variety of malfunctions of the apparatus when they occur, and to activate controls for preventing damage to such apparatus or injury to personnel upon the occurrence of such malfunctions.

Abstract: A system is provided for accurately positioning bales of fibrous material in relation to a mechanical means for transporting fibers from said bales to the hoppers of fiber feeders.

Abstract: An improved method and apparatus are described for removing the wrapping from a bale of cotton, or other fibrous material, and precisely positioning the bale in a predetermined location for further processing with greater accuracy than heretofore possible and without the necessity of heavy manual labor heretofore required.
