Title: Improvements in methods and apparatus for pickling iron and steel
IPC: C23G1/36
Filed: 1942-12-24
Abstract: 562,596. Pickling iron and steel. SWINDIN, N. Dec. 24, 1942, No. 18331. [Class 82 (ii)] [Also in Group III] Iron and steel is pickled in a bath composed of hydrochloric acid saturated with ferrous sulphate and preferably maintained at 50‹- 60‹ C. and when the acid balance of the bath is upset by the decomposition of hydrochloric acid, the latter is regenerated by the addition of sulphuric acid in an amount approximately equivalent to the ferrous chloride present so that the excess of ferrous sulphate is thrown out of solution in a form having only one or two molecules of water and is removed. The bath may be formed by carrying out a preliminary pickling with hydrochloric acid until the free acid is reduced to a “ or ¢ of its original make-up, adding sulphuric acid while maintaining the temperature at 40‹ C. and then raising the temperature to 50‹ or 60‹ C. for cyclic regeneration of hydrochloric acid and elimination of the ferrous sulphate. Alternatively the bath may be formed by adding to a strong solution of brine and anhydrous ferrous sulphate the equivalent amount of sulphuric acid to form hydrochloric acid and then eliminating the sodium salts formed. Acid liquors are lifted by a pump B via a line 4 from the channel 3 in the sloping bottom 2 of the pickling tank 1 into a line 5 and delivered to the bottom of a settling tank C, the acid flowing upwards and overflows as clear liquor into an annular trough 6. The suspended particles, e.g. scale dust ferrous particles and anhydrous ferrous sulphate are removed by valve 18 and pass into a filtering tank D, the filtrate draining by a pipe 19 into the tank.. The liquor from the trough 6 passes by a pipe 7 into a decomposing tank E fitted with an agitator 21 and connected by a conduit 20 controlled by a valve 22 to a sulphuric acid tank F. The precipitated ferrous sulphate is removed by opening a valve 9 passing down a pipe 10 into a centrifugal machine provided with a revolving basket. The filtrate passes by a pipe 16 to a tank 5 from which acid is passed back to the tank 1. The tanks S, C, D and the pipe 19 may be omitted. The pump B may be of the kind described in Specification 551,528 and the whole of the vessels and acid-contacting parts may be rubber or ebonite covered.

Abstract: 1535971 Making composite superconductors TOKYO SHIBAURA ELECTRIC CO Ltd and SHOWA ELECTRIC WIRE & CABLE CO Ltd 7 May 1976 [31 July 1975] 18885/76 Heading B3A [Also in Division H1] A method of making a composite superconductor comprises forming a stock product 1 from portions of Nb or Nb alloy 4 and Sn alloy 2 with a Cu portion 3 interposed between them, placing the stock product in intimate contact with a matrix (7), Fig. 2 (not shown), having good thermal and electrical conductivity so as to form a composite body, submitting the composite body to a cross-section reducing treatment and heat treating the reduced composite body. The stock product is placed in a copper jacket 5 and drawn to provide good mechanical contact between its constituent elements. A stabilized multi-filamentary superconductor is made by placing a plurality, e.g. several dozen to several hundred, of drawn stock products in the matrix (7), which is also of copper. Alternatively, the jacket 5 and matrix (7) may be of Al or Cu-Al alloy. The assembly is then drawn down to the required size and heat treated at 700 C. for 25-100 hours depending on the thickness of the Nb tube 4. The Cu plays a catalytic role in the formation of Nb 2 Sn resulting in a reduction in the reaction temperature, while the use of a Sn based alloy eliminates the need for heat treatment between cold working processes. Prior to insertion in the matrix (7), the stock product may be rolled flat, Fig. 3 (not shown), or it may be comprised of a Cu core (11), Fig. 4 (not shown), clad with a Nb tube (12) surrounded by a Cu jacket (13) surrounded in turn by a Sn-Cu alloy tube (14). The assembly is then surrounded by a Cu, Al or Cu-Al alloy matrix (9).
