Filed: 1955-07-08
Abstract: <PICT:0793560/III/1> In a process for scrubbing coke oven gas or other gas containing ammonia, hydrogen sulphide and hydrogen cyanide with spent pickling liquor comprising ferrous sulphate and sulphuric acid in countercurrent flow so as to produce an ammoniacal ammonium sulphate solution and a sludge comprising ferrous hydroxide, ferrous sulphide, and ferrocyano compounds, the sludge and ammonium sulphate solution are separated in a separator 23, the sludge from line 5 together with additional acid from line 3 and optionally water from line 4 is mixed with the spent pickling liquor from line 2 in a decomposition zone 1 so as to produce a pH of 1-6, the pretreated spent pickling liquor is passed via line 8 to a two-stage scrubbing zone comprising a first section 11 at a pH of 1-7 in which ferrous hydroxide is precipitated, and a second section 20 at a pH of 7-9.5 in which ferrous hydroxide, ferrous sulphide, and ferrocyano compounds are precipitated, hydrogen sulphide and a residue comprising ferrocyano compounds are recovered through lines 6 and 7 respectively, the ammonium sulphate solution is passed via line 14 to a vessel 15 wherein it is mixed with all or part of the solution from the first section 11 of the scrubbing zone (the remainder, if any, being passed to the second section) so as to produce a further precipitate of ferrous hydroxide and preferably so as to produce a neutral solution, the resulting ammonium sulphate solution and ferrous hydroxide are separated in a separator 17, the ferrous hydroxide is removed via line 18, and the ammonium sulphate solution is passed partly to the second section 20 of the scrubbing zone via line 19 and partly to a crystallization zone 25 via line 24 for the recovery of ammonium sulphate.  The gas may be pretreated so that the ammonia content is at least equivalent to the sum of the hydrogen sulphide and hydrogen cyanide contents by scrubbing with ammonia liquor.  The pretreated spent liquor from the decomposition zone may be degassed in a degasefier 9 before passing to the scrubbing zone by passing therethrough purified gas via line 12a which is then recycled via line 10 to the crude gas entering the scrubbing zone via line 21. The solution to be processed for the recovery of ammonium sulphate may be purified by treating with hydrogen sulphide-containing gas, preferably that evolved from the decomposition zone through line 6, removing precipitated compounds, neutralizing the solution with sulphuric acid, and degassing with gas free from hydrogen sulphide. After treatment with hydrogen sulphide, the solution may alternatively be heated and degassed with gas free from ammonia and hydrogen sulphide, e.g. scrubbed gas from line 12.

Title: Method of indicating the tuning condition of a television receiver
IPC: H04N5/50
Filed: 1958-06-20
Abstract: 863,042. Radio receiving circuits. STANDARD TELEPHONES & CABLES Ltd. June 20, 1958 [June 22, 1957], No. 19829/58. Class 40(5) In a television receiver the picturetube is used for tuning indication, the indication modifying the size of a narrow vertical strip across the centre of the picture. Line frequency oscillations from line A are passed through a filter 2 to select the fundamental frequency, which is fed via a phase-shifting network 3 to a frequency-doubler 4. The output of the doubler comprises a train of positive-going "spikes" (Fig. 5, not shown) of twice line repetition frequency which is applied via a blocking condenser to the grid of an amplifier 6 (also Fig. 6, not shown). To this grid is also applied, from terminal C, a D.C. voltage which is dependent upon the accuracy of tune, the output of the amplifier comprising voltage pulses (Fig. 7, not shown) whose height and width is proportional to the magnitude of the D.C. voltage. These voltage pulses are fed via a condenser to a clipper 7 (also Fig. 8, not shown), the output of which comprises current pulses of uniform amplitude but whose width is proportional to the D.C. voltage. These are combined with the video signal, either by superposition in the video rectifier circuit or by application to an otherwise unused electrode in a video amplifier or the picture tube : a vertical bar of variable width is produced, across the centre of the picture (Fig. 1, not shown). The sensitivity may be increased by width modulating the pulses with a saw-tooth wave of frame repetition frequency, in which case the indication comprises a triangular area of variable height and width (Fig. 2, not shown). The modulating wave may alternatively be triangular or paraboloid in shape, and may give a pair of triangular indicating areas of variable separation (Fig. 3, not shown). The modulating waveforms are applied to the grid of amplifier 6 via line C<SP>1</SP> and blocking condenser K. The indicating pulses which occur during the line retrace periods-the frequency being double line repetition frequency-may be suppressed, either by the normal receiver blanking or by applying a line-frequency blanking pulse to stage 6 or 7. Alternatively the output of the frequencydoubler 4 may be combined with a waveform of the fundamental line frequency (Fig. 10, not shown), obtained over a phase-shifting network 8.

Title: Improvements in electrical resistances
IPC: H05B3/14
Filed: 1924-08-25
Abstract: 223,875. McQuinn, T. H., and Evans, P. Oct. 22, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Powdered resistances; materials.-Granular or finely-divided carbon in any of its allotropic forms is used as a resistor in electric heaters, rheostats, switches, motor armatures and controllers and transformers. When high resistances are required, one or more non-conductors may be mixed with the powdered carbon. Asbestos, silica, borates, silicates, oxides or fluorides may be used for this purpose. The powdered carbon may also be used in the form of a paste by mixing it with wax or a mineral oil. In Fig. 1 the resistance material is placed in concentric grooves 4 on a base 1 of refractory material and is retained in position by a cover 2 of the same substance. The cover 2 is secured by bolts 3 and is readily removable to renew the resistor. Conducting studs 6 passing through the base 1 are in contact with the resistor and are wired as shown in Fig. 3. Alternatively, the resistance material may be placed in a carbon casing 8, Fig. 4, having a non- conducting cover 11 supporting a conducting bar 14 in electric connection with a terminal 15. A second terminal 10 is provided' in the base of the casing. In the form shown in Fig. 6, the resistance is placed in a series of pockets 21 in a casing of non-conducting material. Current is supplied through two conducting rods 17, 18 which pass through all the pockets and are attached to a plate 22 secured to the casing. In another form the casing is not divided into pockets, the resistor being in the form of a single rectangular mass penetrated by the two conducting rods 17, 18.

Title: Improvements in automatic differential balances
IPC: G01G3/10
Filed: 1957-06-25
Abstract: 844,170. Differential weighing-apparatus. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. June 25, 1957 [June 29, 1956], No. 20061/57. Class 40 (1). A specimen is suspended from a differential balance system and an electromotive force proportional to the displacement of the balance from its null position is derived and integrated by a servomotor or a coulometer and maintains the balance substantially in its null position. The electromotive force necessary to do this is measured and gives the rate of change of weight of the specimen. In one embodiment (Fig. 2) the specimen 4 is suspended from an arm of a beam 2 attached to a torsion wire 1 fixed at 8 and attached via a torsion head to a motor through a high gear ratio at 14. A small A.C. signal is also applied to the motor in order to increase the linearity of its response. A lightsensitive cell at 10 is used to detect the displacement of the beam and the output of this device is fed through a magnetic amplifier and rectifier mixed with a bias from biasing means 17 and fed to the motor. This mixed output is also fed to a voltage divider 20 from where it is passed to a recording device 21. A slide wire 24 attached to the torsion head is fed with a small D.C. potential and its output is indicative of the cumulative weight change and is added to a small correcting voltage derived from voltage divider 20 for correcting the error due to the retarded position of the torsion head and is also fed to recorder 20. The specimen being weighed is contained in an electrical furnace and the temperature of this furnace is caused to vary linearly with respect to time and is also recorded on recorder 21. An alternative means of converting the deflection of the beam into an electromotive force using a phototransistor and an associated circuit is described. A further embodiment of the invention is described wherein the specimen is suspended from one arm of a balance and the silver anode of a coulometer is suspended from the other. The deflection as before is sensed by a light-sensitive device and the resultant signal is amplified and causes a current to flow through the coulometer to change the weight of the suspended electrode.
