Title: Improvements relating to ammonia saturators
IPC: C01C1/24
Filed: 1955-09-27
Abstract: <PICT:0805558/III/1> <PICT:0805558/III/2> In operating an ammonia saturator, where lye is drawn off constantly into a settling tank and, after separation of tarry impurities, and possibly reheating, is returned to the saturator, a circulation of lye is maintained between the settling tank and an intermediate tank, so that the lye reaches the intermediate tank by an overflow from the settling tank, and is pumped back to the settling tank from a layer of liquid in the intermediate tank as free from tar as possible, and the separation of tar takes place wholly, or mainly, in the intermediate tank.  The fuel gas to be treated enters cylindrical saturator 10 having a conical bottom 11, through inlet 13 in lid 12, and passes through dipping pipe 14 and distributer ring 15.  After reaction of ammonia with the acid, e.g. sulphuric, the gas is withdrawn through 18 and crystals are removed by ejector 19.  Lye overflows constantly through 20 to a settling tank, from which it is returned by pump 21, through heater 22, pipe 23, vessel 24, and pipe 25, to the saturator.  The settling tank has a conical base 27 surmounted by cylindrical portion 26, and has tray 28 suspended therein.  Lye inlet 29 connected to overflow 20 reaches nearly to the bottom of tray 28, and the lye rising in tray 28 round inlet 29 passes through the tray outlet, which is still in the liquid, against deflector plate 30a, which imparts vigorous, preferably rotary, movement to the lye in the upper part of the settling tank.  The lye passes constantly through overflow 32 to intermediate tank 33, which is preferably the acid-resistant lined tar pit.  The tar separates as the lye comes to rest in the intermediate tank, and substantially tar-free lye is sucked out from the bottom of the intermediate tank 33 by ejector 34, and is returned to the settling tank through pipe 31, which is tangentially directed, to increase the rotary movement of the upper layers of lye in the settling tank, with consequent inhibition of tar separation.  The pump 21 sucks lye, from the bottom of the settling tank, through pipe 46 for return to the saturator.  The tar may be hand-skimmed from the surface of tank 33, but preferably a tarcollecting tank 35 is used.  This tank (Fig. 3) is suspended in the intermediate tank at the correct level, and tar enters opening 37 through strainer 36.  The tar in the tank 35 raises float 38, closing opening 37, and opening steam valve 42 by linkage 40, when steam, flowing through pipe 43, drives tar out through pipe 44 to storage. The float 38 and valve 42 may be manually operated by lever 41.

Title: Process for the production of mineral wool products
IPC: C03C1/00
Filed: 1977-06-30
Abstract: An hydraulic binder, a particulate material and in particular an inorganic particulate fine material containing at least 75% of SiO2 are used to form a mouldable mixture. The average particle size of the SiO2-containing fine material is less than 100  mu m. The mixture is used to form mouldings. These are then melted in a melt oven and made into mineral wool products. The admixture of the SiO2-containing fine material results in mouldings which retain their shape in the course of the melting process until their surface starts to melt.

Title: The manufacture of new derivatives of higher fatty acids containing nitrogen
IPC: C11C3/00
Filed: 1929-09-11
Abstract: 339,675. Carpmael, A., (I. G. Farbcnindustrie Akt.-Ges.). Sept. 11, 1929. Fatty acid derivatives containing nitrogen are obtained by treating halogenated fatty acids having more than eight carbon atoms in the molecule and which may contain hydroxy groups and be saturated or unsaturated, with solutions of ammonia in organic solvents. Copper or a copper compound may be used as a catalyst and pressure may be employed in the reaction. Carboxyamides are at first formed, and in part esters, when alcohols are present. The halogen atoms are gradually replaced by amino groups, and also may be split off with formation of double bonds. The products, which are saponified by means of hot alkalies have soap-like properties and may be used in the textile industry. According to examples, (1) hexachlororicinoleic acid. prepared by introducing chlorine into the parent acid is heated in an autoclave with a solution of ammonia in ethyl alcohol. At first a mixture of chlorinated unsaturated fatty acid and a carboxyamide is formed, but on continuing the reaction at raised temperature, a mixture of an ester with a carboxyamide or an inner salt formed by amino and carboxylic groups results. A tetrachlororicinoleic acid, similarly yields a product having less basic products; (2) hexachlorstearic acid prepared according to example 7 of Specification 336,623 is treated with ammonia dissolved in methyl or butyl alcohol or acetone, under pressure in the presence of copper sulphate as catalyst: (3) a chlorinated linoleic acid is heated with alcoholic ammonia. The product contains two amino groups, two chlorine atoms and one double bond.

Title: Modified drying oil and method of making
Inventor: WILLIAMS GORDON MITCHEL
IPC: C09F7/00
Filed: 1950-11-14
Abstract: The siccative power of double bonded fatty oils and fatty acids thereof is increased by halogenating at least a portion of the double bonds of the fatty compounds and thereafter reacting the halogenated product with a metallic-unsaturated aliphatic compound to eliminate a metal halide.  Specified metallo-compounds are 1-sodium-1,2-propene, 1-sodium-oxybutadiene and magnesium-di-propene-1.  For the best siccative results only a few points of unsaturation of the original oil should be halogenated since a too complete halogenation leads to polymerized products. In examples: (A) hempseed oil is treated with 1/4 of the theoretical quantity of bromine in the absence of strong light and then with 1-sodium-1,2-propene at 250 DEG  F.; and in (B) chlorine is bubbled through fish oil and the product treated with 1-sodium oxybutadiene at 250 DEG  F.

Abstract: 1,178,818. Measuring flash point. PRECISION SCIENTIFIC CO. June 13, 1968 [June 14, 1967], No.28178/68. Headings G1D and G1N. In the automatic determination of the flash point of a liquid in which the liquid is continuously supplied to a heating chamber 14, Fig.1, where it is heated at a controlled rate so as to produce a vapour which rises into a flash chamber 17 together with air from an inlet 20, and in which the airvapour mixture is ignited at the flash point by a spark periodically produced between electrodes 24, 25', detection by a thermocouple TCV of the sudden increase in temperature consequent upon ignition causes the liquid to be diverted by a solenoid-operated valve 12 from the heating chamber 14 into the air inlet 20. This arrangement causes rapid cooling of the flash chamber 17 before the next test cycle commences. The heater 15 of the heating chamber is supplied with a constantly increasing voltage from a motor driven variable transformer (35, Fig.4, not shown), and the liquid passes through the chamber between an inlet 10 and an outlet 23. The temperature of the liquid is detected by a thermocouple TCL and indicated on a recorder 26. When the flash point is reached, the output pulse from thermocouple TCV is supplied to a magnetic amplifier (33) and causes de-energization of the heater. At the same time a reverse D.C. voltage from a converter (43) is applied to the recorder to cause an abrupt drop in the recorded trace, the peak temperature recording being the flash point of the liquid. Other operations consequent on the output pulse from thermocouple TCV are the rotation of valve 12 to divert the liquid from the heating chamber, the disconnection of the electrodes from the pulse generator and reduction of the heater voltage by reversal of the motordriven variable transformer. To prevent an excessive temperature rise in the heating chamber driving a test, a thermocouple TS2 is connected to a shut down circuit.
