Abstract: 1,198,883. Sodium tripolyphosphate. MONSANTO CO. 12 June, 1968 [12 June, 1967], No. 27949/68. Heading C1A. A process for the production of sodium tripolyphosphate comprises calcining a sodium orthophosphate salt in the presence of an amount of a source of potassium ions not exceeding 5% by weight of the sodium orthophosphate salt. Potassium hydroxide, phosphate and carbonate are preferred as potassium sources. The method of calcination is not important providing (a) the potassium source is uniformly distributed throughout the orthophosphate and (b) no more than 20% (preferably 10%) wt. of the sodium orthophosphate has been condensed to polymeric salts before the addition of potassium. Calcination temperatures do not exceed 520‹ C. and are preferably in the range 350‹ to 480‹ C. The examples illustrate the calcination of a slurry prepared from soda-ash and phosphoric acid in a gas-fired rotary stainless steel calciner and calcination of a mixture of monosodium orthophosphate, disodium orthophosphate water and pentapotassium orthophosphate in a fluidized bed reactor at 450‹ C. using sodium tripolyphosphate particles for the fluidized bed.

Patent GB-427394-A (GB)
Title: Improvements in the removal of weak acids from gases
IPC: C01B32/50
Filed: 1933-10-14
Abstract: In the removal of weak gaseous acids, such as carbon dioxide or hydrogen sulphide, from gases containing them by scrubbing the gases with a liquid medium, the active constituent of which is an alkaline compound and heating the spent medium to regenerate it, the gases and vapours evolved in the regeneration step are cooled and the aqueous condensate thus formed on the aqueous portion thereof is evaporated, the resulting vapours being returned to the circulating scrubbing medium.  Any basic constituents driven off with the acidic gases in the regeneration are thereby returned to the circulating liquor.  The alkaline compound may be a weak or strong organic base or the salt of a strong inorganic base with a weak inorganic or organic acid such as an aminocarboxylic acid, a phenol or an aminosulphonic acid.  The condensate is preferably obtained under such conditions that it does not contain any of the weak gaseous acids, e.g. in a counter-current dephlegmator from which the condensate is withdrawn at as high a temperature as possible.  According to one example, a coke oven gas containing benzene and hydrogen sulphide is washed with a solution of butyl diethanolamine in a washing oil.  The saturated oil is treated directly with steam after being heated to 130 DEG  C.  The gases and vapours evolved are condensed by cooling, the benzene is separated from the condensate and the remainder is evaporated whereby the steam to be blown directly into the saturated oil is produced. According to a second example, a gas containing carbon dioxide and hydrogen sulphide is washed with an aqueous solution of monoethanolamine containing boric acid.  The saturated solution is treated directly with steam in a regenerating column.  The condensate from the waste gases is vaporized and the steam thus obtained containing the basic constituents precipitated in the condensate is introduced into the regenerating column.  Any bases contained in the weak gaseous acids, in any hydrocarbons withdrawn from the condensate, or in the purified gases may be recovered by scrubbing with sulphuric acid or the like.
Patent GB-466251-A (GB)
Title: Improvements in and relating to electric cutouts
IPC: H01C7/10
Filed: 1936-10-20
Abstract: Metal oxide cutouts are made by oxidizing the metal to form an oxide coating having a thickness sufficient to give a breakdown value greater than that desired, the thickness of the coating being then reduced in an acid bath to the thickness which gives the desired breakdown value.  The coated metal may then be annealed to stabilize the breakdown characteristics of the coating.  Copper may be oxidized at about 1055 DEG  C. to form a coating of red and black oxides, the metal is then cooled and washed in a sulphuric acid bath to remove a substantial proportion of the black oxide and to leave a coating of the desired thickness and breakdown value.  The metal is then annealed at about 1000 DEG  F. for 11-16 minutes, quenched in a bath at about room temperature, and dried by a current of compressed air the temperature of which is a few degrees lower than room temperature.  If the sulphuric acid bath comprises a solution of 35 cc. of commercial acid in 1000 cc. of water and the treatment is continued until only about 5 per cent of the original black oxide is left, the finished article will have a breakdown value of between 50 and 90 volts.

Filed: 1975-07-08
Abstract: 1496946 Rolling sheets NIPPON KOKAN KK 8 July 1975 [6 Aug 1974] 28653/75 Heading B3M  The flatness of a metal sheet 5 being rolled between rolls 1 is controlled by changing the tension distribution across the width of the sheet by means of short rollers 4 which are individually vertically displaceable against the sheet. A local increase in tension in the sheet produces a slight decrease in reduction produced by the rolls 1 in the same region of the sheet. Sensors 6 detect any non-flatness in the sheet and are used to regulate the rollers 4 to produce the desired tension changes. An auxiliary roller 5 may be located on the side of each set of rollers remote from the mill rolls, the roller being cylindrical or crowned and serving to regulate the basic tension acting on the sheet. The method can be applied to hot, cold, or skin-pass rolling.

Filed: 1923-11-17
Abstract: 229,235. Anderson, W., and Brown, W. Nov. 17, 1923. Engines working on special systems or cycles; vapour engines. -An engine works on a four-stage cycle comprising compression, heating at approximately constant pressure, expansion, and cooling at approximately constant pressure. The working- fluid during compression and expansion passes the critical temperature and changes from liquid to vapour and vice versa respectively in the working cylinder. The working fluid is moved from one end of the motor cylinder to the other end by means of a displacer connected to a power shaft driven thereby. The cylinder is heated at its upper end by circulating furnace gases through a jacket j, and is cooled at its lower end by circulating water through a second jacket k. The distribution of the heating and cooling fluids is controlled by cocks i, m worked by the engine. The displacement of working-fluid towards the cold end of the cylinder is done at a relative low pressure, and towards the hot end at a higher-pressure. The change of pressure is effected by a pressure changer c connected to the shaft n. The cylinder or displacer or both may be tapered and the heat jacket lengthened.
