Title: Improvements relating to the treatment of industrial effluents
Inventor: TODHUNTER KENNETH HOPE
IPC: C02F3/12
Filed: 1957-07-31
Abstract: 847,640. Treating waste effluents. SIMONCARVES Ltd. July 25, 1958 [July 31, 1957], No. 24244/57. Class 111. Industrial waste effluents, e.g. coal carbonisation liquors, containing as toxic constituents (a) phenols and (b) thiosulphates, thiocyanates, cyanides and (c) ammonia (fixed or free) are treated with bacteria capable of destroying the toxic constituents while maintaining the pH and temperature of the effluents between limits at which the bacteria are active, and continuously introducing nutrients and oxygen for the bacteria, the bacteria for treating (a), (b) and (c) being respectively Vibrio Cyclosites, Vibrio O1, Pseudomonas S7 and Actinomycetaceae S2; Thiobacillus thiocyanoxidans, Thiobacillus S3, S4 and S5 ; and Nitrobacteraceae S6 to S11. The bacteria may be employed together in a single step treatment of effluents containing the toxic constituents using either percolating filters or sludge tanks inoculated with appropriate bacteria. Preferably the treatment is effected in stages with successive removal of (a), (b) and (c) in that order,, the toxic constituents of each group being reduced to a low concentration before subjecting the effluent to the next stage. Fig. 2 shows a plant for the treatment of coal carbonisation effluents. Effluent from a pipe 1 is passed through a hydraulic cyclone or settling tank 2 for removal of solid material, principally lime, is cooled by heat exchanger 3 and has its pH adjusted at 4 by addition of hydrochloric or sulphuric acid or waste pickle liquor from a tank 5. Nutrient solution for phenol destroying bacteria is added from tank 8. The liquor is pumped into activated sludge tanks 6 and 7 connected in series (as shown), or in parallel, where the concentration of phenols is substantially reduced by phenol-oxidising bacteria with which the tanks have been inoculated, air being introduced into tanks 6 and 7 by devices 24 and 25. The phenolfree liquor passes to a settling tank 9 where activated sludge separates at 11 and is recycled by pump 12. In the second stage, thiosulphates, thiocyanates, and cyanides are removed by passing liquor from 9, via heat exchanger 13, into an inoculated percolating filter 14. In the third stage, effluent now free of phenols, thiosulphates, thiocyanates, and cyanides are passed to sludge tanks 16 and 17 inoculated with ammonia-destroying bacteria. Nutrient solution from tank 19, calcium carbonate (to neutralize acids) from a hopper 20, and air from devices 26 and 27 are also added. Effluent is passed to a settling tank 18 from which it is discharged to waste through line 22 or recycled as dilution water through a pipe 23. One form of sludge tank for phenol and ammonia destruction consists, Fig. 3, of a turbine-type agitator 31 fitted with spaced beades 35 carried on a disc 36, the agitator operating in a tank 32 fitted with baffles. 33 Air is admitted through a sparger 34.

Title: Improvements in and relating to the manufacture of azodyestuffs
IPC: C09B43/10
Filed: 1934-08-24
Abstract: Copper complex compounds of azo dyes are made by treating with an agent yielding copper under conditions such that the two alkoxy groups are split up, the dyes obtained by reducing in a caustic alkaline medium with grape sugar a monoazo dyestuff of the general formula <FORM:0443242/IV/1> wherein R1 may be substituted and R2=the residue of the naphthalene or carbazole series containing at least one SO3H group.  The products which are probably disazoazoxy dyestuffs yield redder shades on cotton and regenerated cellulose. In examples: (1) the dyestuff 5-nitro-2-amino-1-methoxybenzene --> 1-naphthol-3 : 6-disulphonic acid is reduced and coppered with ammoniacal copper sulphate; 8-chlor-1-naphthol-3 : 6-disulpho acid, 1-naphthol-3 : 8-disulphonic acid and 5-nitro-4-chloro-2-amino-1-methoxybenzene may also be used as components; (2) the dyestuff 5-nitro-2-amino-1-methoxybenzene --> (alkaline) 2-(4<1>-or 3<1>-carboxyphenylamino)-8-naphthol-6-sulphonic acid is treated as above; N-(3<1>-sulphophenyl) 2 : 8 : 6-acid, N-(3<1>-carboxy-phenyl)-J acid or 2-amino-5-naphthol-1 : 7-disulpho acid; (3) and (4) the dyestuffs 5-nitro-2-amino-1-methoxybenzene --> 2-naphthol-5 : 7-, 3 : 6- or 3 : 7-disulpho acid, 1-hydroxycarbazole-3 : 6-disulphonic acid or 1 : 8- or 2 : 8-dihydroxycarbazole - 3 : 6 - disulphonic acid are similarly treated.  The Specification as open to inspection under Sect. 91 refers also to the use of functional equivalents of glucose, such as arsenious oxide and formaldehyde as reducing agents and states that the coppering may take place at higher temperatures and under pressure.  The ammonia may be replaced by pyridine or other organic base and the reaction may also be performed in acid medium, e.g. with copper sulphate and sodium acetate.  This subject-matter does not appear in the Specification as accepted.

Title: A new or improved process and apparatus for coating surfaces with plastic and other semi-liquid composition
Inventor: HAWES ALBERT HENRY
IPC: B28C5/46
Filed: 1947-09-06
Abstract: <PICT:0644638/III/1> <PICT:0644638/III/2> <PICT:0644638/III/3> An improvement in the apparatus of the parent Specification consists in the provision of a vessel for effecting preliminary mixing of the composition, said vessel being separate from the closed circuit and having means for transferring the mixture after initial mixing to the main container by the pressure of air or other gas provided for effecting final mixture of the composition.  A further improvement consists in the provision of means for introducing air or other gas under pressure to the mixing circuit at a position immediately adjacent the discharge orifice provided at the base of the main container for discharging the mixture therefrom around the mixing circuit.  Referring to the drawings, air under pressure is supplied to preliminary mixing vessel 60 with air-tight lid 64 through pipe 65 (which carries valve 66) leading via receiver 52 from air compressor 51.  Vessel 60 is connected to vessel 11 by pipe 67 with control valve 68, so that when valves 66 and 68 are opened the mixture is transferred by the pressure of air admitted to the upper part of vessel 60. Further, the pipe 53 carrying air under pressure and controlled by valve 54 is connected to the mixing circuit immediately beneath and adjacent to the discharge outlet 20 (see Fig. 3) the air from this pipe flowing upwardly through perforated grid 21 and hence mixing the contents of vessel 11.  Specification 627,440 is referred to.

Title: D.c. amplifying system
IPC: H03F3/36
Filed: 1946-08-20
Abstract: 633,551. Valve voltmeters, PRINZ, D. G. Aug. 20, 1946; No. 24749. [Class 37] [Also in Group XL (c)] A system for the amplification of direct voltages and/or currents comprises a D.C. valve amplifier and means operated by the output of the amplifier for re-adjusting the correct zero. Fig. 1 shows a D.C. amplifier of conventional type in which improved linearity is obtained by negative feed-back across resistor 9 to the input circuit 6, 7 and in which the zero error may be corrected for by shorting the input and causing the output voltage to vary the setting of the bias potentiometer 11 by means of a motor, Fig. 3 (not shown), until the output voltage is zero. A system of switches is provided which periodically short the input to the amplifier and corrects the zero drift in this manner. Fig. 6 shows a modification in which the correcting voltage is obtained by charging a capacitor 15 from the output of the amplifier during the " correcting zero interval, the input of the amplifier being shorted with switches 16, 17 in the Z position. When the switches are in the A position for normal amplification the input voltage at terminal 6, 7 is placed effectively in series opposition with the amplified zero error voltage of the amplifier and the effective zero error voltage is reduced by a factor equal approximately to the forward gain of the amplifier. Normal negative feed-back is applied to the input by resistor 9, the meter 8 indicating the output of the amplifier. The switch may be operated repeatedly, e.g. by an electric motor at intervals small enough to reduce the effect of zero drift during these intervals to negligible values. The amplifier may be used to operate a recorder of the " dotting " type, the operation of the zero drift correction switch then being synchronized with the printing cycle of the recorder. Two such amplifiers may be connected in parallel, the zero correcting switches being synchronized so that one amplifier is always in the normal amplifying position. In order that the external D.C. connection between one input and output terminal of the amplifier should not affect the performance of the amplifier, means may be provided to interrupt the D.C. connection between the initial and final stages. Reference has been directed by the Comptroller to Specification 620,140, [Group XL (c)].
