Patent GB-869218-A (GB)
Title: Improvements relating to the picking of ferrous surfaces
IPC: C23G1/36
Filed: 1959-06-04
Abstract: Ferrous metal surfaces are pickled using an aqueous phosphoric acid solution containing ferrous and ferric ions in a ratio between 11 : 1 and 1 : 7 the ferrous ion concentration being controlled by removing some of them by treatment with an ion exchange resin, so as to maintain the concentration of ferric ions between 20% and 85% of the saturation concentration.  The pickling solution may contain 15-45% phosphoric acid, and the desired ferric ion concentration may be maintained by continuously recirculating a portion of the solution through a bed of said resin.  The solution may contain inhibitors such as dibutylthiourea, di-isopropylthiourea, or sodium iodide. Pickled surfaces may be given a flash coating of nickel, cobalt, or a nickel cobalt alloy prior to vitreous enamelling.  The nickel or cobalt coating may be formed from an aqueous solution of a nickel or cobalt salt which also contains controlled quantities of hypophosphite radicals, and a nickel cobalt coating by treating the surface with a bath containing nickel sulphate, cobalt sulphate, boric acid, citric acid, dextrose, sodium hydroxide, chromic oxide, glutamic acid, and sodium bisulphite.  In using this solution the bath is maintained at a pH of 4.9-5.1 and the pickled surface is contacted with the solution for 15/20 minutes. The coated surface may be heated in an oxidizing atmosphere at 1100-1900 DEG F. for 1-10 minutes.  Instead of using a nickel or cobalt coating a phosphate coating may be formed in the conventional manner and heated in air at 1100-1900 DEG F. for 3-15 minutes, to convert it to an oxide-phosphate coating prior to vitreous enamelling.

Title: Improvements in or relating to reduction valves for pressure liquids
IPC: G05D16/10
Filed: 1944-10-06
Abstract: 587,901. Fluid -actuated valves. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 6, 1944, No. 19229. Convention date, Oct. 7, 1943. [Class 135] In a reducing valve having a pressure liquid inlet 22 and an outlet 23, the pressure is reduced by a spring- loaded valve 14 which coacts with a seat 13, adjustable through a screw 17 and wheel 18 to control the pressure at the outlet. The valve 14 is formed integrally with a relief valve 16, which coacts with a seat at the end of a relief passage formed in a piston 12, which is pressed downwards by air introduced through an inlet 19 and imprisoned in the cylinder 11 by pressure liquid admitted initially through the inlet 22, past the valve 14 into the chamber 43 beneath the piston, and thence past the piston packing 20. When the pressure in the chamber 43, and therefore in the outlet 23, falls below the desired value, the piston moves downward and opens the valve 14, thus allowing more liquid to pass to the outlet. If the pressure in the outlet rises above the desired value, the piston moves upward, thus allowing the valve 14 to close and the relief valve 16 to open.
