The valves 18 and 10 are preferably opened with a slow or dashpot action. A delay action switch is included in the circuit of the motor 4. When the motor 4 is being started up an overload clutch holds the 17, 9 and 16 circuits open. The immersion heaters may be thermostatically controlled. The drive to the stirrers 3 may be periodically interrupted to allow for the usual yeast action. A time switch in the circuit of the motor 4 may arrest mixing after a predetermined period. The electric immersion heaters 9 and 17 may be replaced by steam coils. Specification 539,616 is referred to.

Patent GB-1043466-A (GB)
Title: Melamine synthesis
IPC: C07C273/12
Filed: 1964-02-18
Abstract: Melamine is synthesized from urea by a process in which urea is synthesized at an elevated temperature and pressure from ammonia, carbon dioxide and a recycled stream of ammonia and carbon dioxide, the urea synthesis stream containing ammonium carbamate is processed to generate a first off-gas containing ammonia and carbon dioxide, which off-gas is at least part of the recycle stream, and to form a residual urea synthesis stream which is processed to anhydrous urea, at least part of the urea is melted and heated at elevated pressure to form melamine and a second off-gas containing ammonia and carbon dioxide, and the second off-gas is combined with the first off-gas to form the recycle to the urea process.  The conversion of urea to melamine may be conducted in the presence of an excess of ammonia. The recycled ammonia and carbon dioxide may be converted to ammonium carbamate prior to the urea synthesis.

Filed: 1917-05-16
Abstract: 107,374. British Westinghouse Electric & Manufacturing Co., (Assignees of McCulloch, L.). June 8, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Resistances.-A resistance for heating, regulating, &c., is coated with a boron compound containing oxygen, for instance boron trioxide, one of the sodium borates, or lead borate. With this compound may be mixed a small proportion of a filler such as kaolin, silica, a metallic oxide, or a clay of the " Bentonite " type. The resistance conductor may be an iron or other alloy, for instance nickel-steel containing 30 per cent. of nickel, copper-nickel containing 40 per cent. of nickel, or German silver. It may be dipped in or brushed with a solution or suspension of ammonium orthoborate preferably in ammonia water, or of boric acid in water, alcohol, glycerine, turpentine, &c., being then heated to aboot 500‹ C. to drive off water and ammonia. Boron trioxide or boric acid may be applied also as a dry powder and spread over the conductor when softened after being softened by heating. It is convenient to apply the coating after the resistance is mounted on its insulating-support, for instance of mica, lava, &c. in heating-apparatus such as sad-irons and percolators. The whole structure may be thus coated. The coating may be protected by refractory cement. It is softened, but not melted, by temperatures usually attained by resistances, and it has good heat conductivity.

Filed: 1929-03-04
Abstract: 307,303. I. G. Farbenindustrie Akt.- Ges. March 2, 1928, [Convention date]. Samples furnished. Monoazo dyes are made by coupling a diazotized amine of the general formula- (in which one x = an acidylamino-group, the other x and y an alkyloxy- or a methyl group, but in any case only one of the symbols x and y being a methyl-group) with a component of the general formula- (in which " ac " = an acidyl group and n = 1 or 2). The products dye wool from an acid bath clear reddish-violet to greenish-blue shades. The following dyestuffs are specified : (1) 5-acetamino- 2-amino-1 : 4-dimethoxybenzene # N-acetyl-H- acid. The acetyl group in H acid may be replaced by a carbethoxy-, chloracetyl-, #-chlorpropionyl-, phenylacetyl- or a substituted or unsubstituted benzoyl-residue. (2) 6-amino-4- acetylamino-1 : 3-dimethoxybenzene # N- acetyl-H acid. The acetyl-residue in the first .component may be replaced by a benzoyl-residue. (3) 4-methoxy-5-acetamino-2-amino-1-methylbenzene # N-acetyl-H acid. The acetyl-residues in both components may be replaced by other acidyl residues. (4) 5-Amino-4-ethoxy-2-acetylamino-1-methoxybenzene # N-(4<1>-toluenesulpho)-H acid or N-(5<1>-acetylamino-2<1>-methylbenzenesulpho)-H acid. S - Amino - -4-ethoxy-2-acetylamino-1-methoxybenzene is made by acetylating 1-methoxy-2- amino-4-ethoxy-5-nitrobenzene and reducing. N-(5<1>-acetylamino-2<1>-methylbenzenesulpho) H acid is made by treating H acid with 4-nitrotoluene-2-sulphochloride, reducing and acetylating. The Specification as open to inspection under Sect. 91 (3) (a), comprises also diazo components of the above general formula when x and y = an aralkyloxy or aryloxy group and 6-amino- 4-#.chlorethanesulpho- or toluenesulphoamino- 1 : 3-dimethoxybenzene. In an example the dyestuff 5-amino-4-phenoxy-2-acetylamino-1-methoxybenzene # N-acetyl-H acid or N-(#-chlorethane sulpho)-H acid is described; the phenoxy group in the diazo component may be replaced by a benzylhydroxy residue. Reference is also made to dyestuffs derived from diazo components of the general formula above in which x may be a heterocyclic ring attached through a nitrogen atom and from coupling-components of the above general formula in which ac may be the residue of a heterocyclic ring. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 12679/98 and 22886/99.
