Title: Manufacture of new chromiferous monoazodyestuffs
Filed: 1949-02-21
Abstract: 2 : 5 - Dimethoxy - aniline - 4 - sulphonic acid is obtained by (1) heating the acid sulphate of 2 : 5-dimethoxy-aniline, or (2) sulphonating 2 : 5-dimethoxy-aniline with sulphuric acid or with chlorsulphonic acid in the presence of tetrachlorethane.ALSO:Monazo dyestuffs of the formula <FORM:0665372/IV (c)/1> where R1 is a benzene nucleus with the -OA2 and -OA2 groups in the 2 : 5-positions with respect to the azo group, A1 and A2 are alkyl or cycloalkyl and R2 is a naphthalene nucleus with at most one sulphonic acid group (the hydroxy and azo groups being in the 1 : 2- or 2 : 1-positions), are treated with a chroming agent so that the group A1 is split off. The benzene nucleus may be further substituted, e.g. by chlorine, bromine or fluorine.  A1 and A2 are preferably methyl or other alkyl groups up to C4.  The naphthalene nucleus may be further substituted, e.g. by methyl or bromine.  Chroming may take place on the pure monoazo dyestuff or on the crude coupling mixture obtained in its preparation, with suitable adjustment of pH.  Various chromium salts are suitable, in an acid medium at 110-140 DEG  C.  The products are suitable for dyeing and printing animal fibres (e.g. wool, silk, leather) and superpolyamides and superpolyurethanes. The starting materials are made by diazotizing and coupling the appropriate components in the usual way.  In the examples: (1) the dyestuff 2 : 5-dimethoxyaniline-4-sulphonic acid --> 1-naphthol-5-sulphonic acid is chromed with chromic sulphate; 2-naphthol-4-sulphonic acid may also be used; (2) as in (1), using 2-naphthol; (3) wool is dyed with the product of example (2). Other suitable coupling components are listed.  Specification 296,819 is referred to.  The Specification as open to inspection under Sect. 91 refers to the production and chroming of similar dyestuffs containing in the benzene nucleus instead of the sulphonic acid group, a group -SO2X, where X is alkyl, aryl or aralkyl, or a group -SO2NR3R4, where R3 is hydroge or alkyl and R4 is hydrogen, alkyl, aryl or aralkyl.  In this case, the naphthalene residue must contain one but not more than two sulphonic acid groups.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in cooling and maintaining cool double walled liquefied gas transport tanks
IPC: F17C3/10
Filed: 1966-03-14
Abstract: 1,135,965. Liquefied gas storage containers. J. J. McMULLEN. 14 March, 1966 [15 March, 1965; 16 March, 1965; 24 Sept., 1965], No. 4825/68. Divided out of 1,135,963. Heading F4P. Cooling of a liquefied gas, e.g. methane, cargo tank having spaced inner and outer walls 24, 22 and insulation 20 spaced from wall 22 is effected by circulating through the insulation and interwall spaces nitrogen gas having been cooled at 44 by heat exchange with liquid methane withdrawn from a storage tank 48, and the so-vaporized methane is passed through pipes 50, 52 to the interior of the cargo tank. The cold nitrogen gas leaving exchanger 44 is circulated through a pipe 30 in the insulation space and is returned through an aperture 32 in said pipe 30 and through a pipe 38 to the inlet of a blower 40 which discharges into exchanger 44, whilst a portion of cold nitrogen leaving aperture 32 passes through an aperture in the outer wall 22 into the interwall space and is returned through an aperture 38a to the blower inlet. The tank is also cooled by liquid methane from storage tank 48 passing through a spray pipe 60. Final cooling is effected by passing liquid nitrogen instead of liquid methane through exchanger 44. During cooling, methane vapour is withdrawn from the cargo tank through a pipe 53 and is either heated at 54 for use as fuel gas or is returned to a liquefier 58. Prior to the abovementioned cooling, the cargo tanks, insulation space and interwall space is dehydrated then purged with nitrogen gas at 0 C. withdrawn from a source 36 and passed through pipes 30, 34; the purged nitrogen being withdrawn from the interwall and insulation spaces by blower 40 which then delivers to atmosphere through a pipe 46. The cargo tank is then filled with liquid methane through line 60 and the circulating nitrogen is cooled by withdrawing by means of a pump (not shown), a small portion of liquid cargo and passing it through exchanger 44 and returning the methane vapour to the tank through pipes 50, 52. After unloading the cargo the circulating nitrogen is cooled by a portion of residual methane being passed through exchanger 44.

IPC: F27B3/26
Filed: 1926-02-23
Abstract: 248,012. K³hn, P. Feb. 23, 1925, [Convention date]. Open-hearth furnaces.-In a furnace for smelting and refining iron, steel and other metals, fuel in solid, liquid or gaseous form is injected by burners f at an angle of about 90‹ into a stream of heated air passing through the furnace so that hot short narrow flames are directed on to the charge. The waste gases traverse the rest of the hearth, and then pass through regenerating chambers a, b, and through other adjoining regenerating chambers arranged in series so as to provide an unusually long path for preheating the air for combustion, and thus give up practically the whole of their beat before passing to the chimney, the said heat being utilized for preheating the air for combustion of the fuel, the air passing in opposite direction to the gases. The waste gases are cooled to about 1100‹ C. in traversing the chambers a b and to about 100‹ C. in passing through the other regenerative chambers. The slag formed in the chequer work flows back to the hearth. The fuel used may comprise distillation, lighting and coke oven gases, tar and mineral oils, tar, pulverized coal and mixtures of poor gases with pulverized fuel, distillation gases, &c.
