IPC: C01C1/247
Filed: 1930-02-10
Abstract: Ammonium sulphate is made by the reaction of dry ammonia and sulphur dioxide and treatment of the product, which has the formula NH4.SO2.NH2, with water or steam, and oxygen or oxidizing gases, if desired in the presence of known oxygen carriers, such as cobalt, nickel or iron, salts, e.g. cobaltous or nickelous sulphate, a solution of which may be sprayed into the reaction chamber.  The first reaction may be effected at ordinary temperatures, but, to favour the subsequent oxidation, temperatures of 100 to 120 DEG  C. are used.  The pressure may be greater than, less than, or equal to atmospheric.  Dry sulphur dioxide and ammonia are introduced continuously into the top of a vertical tube fitted with a stirrer, and having an internal temperature of about 115 DEG  C.  The walls are cooled to produce deposition of the intermediate product, which is scraped off and is oxidized to ammonium sulphate by an upward current of humid air.  Rather less than the theoretical amount of water is used to obtain a dry product.

Abstract: 1330440 Soldering BUCKBEE-MEARS CO 1 Feb 1972 [8 July 1971] 4559/72 Heading B3R [Also in Divisions B6 C7 and G2] A printing screen comprises a stainless steel mesh 20, with its wires held together by tinlead solder bodies 30, fastened by a tin-lead solder layer 18 to the surface of an apertured nickel sheet 16. The apertures in the nickel sheet are in the shape of the image which it is desired to print, and the initial step in making the screen is to form a resist image on a copper support, e.g. by use of a light-sensitive enamel. Nickel is electrodeposited on the copper support to form the nickel sheet, then tin and lead in eutectic proportions (approx. 60% Sn by weight) is electrodeposited over the nickel to form the layer 18. A stainless steel mesh 20 is electroplated with the same tin-lead solder, and is positioned over the solder- and nickel-coated support, then the assembly so formed is heated to approximately the melting point of the solder and pressure is applied, causing local melting of the solder. The coated mesh is joined to the support by the layer 18, and the solder coating on the parts of the mesh which overlie the resist image migrates towards the intersections of the mesh, which are under greater pressure. Some solder from the layer 18 joins in the migration, and the bodies 30 form at the intersections of the mesh, rigidizing the mesh without closing its pores. Etching away of the copper support and resist leaves the completed screen.
