Title: Improvements relating to the washing and cooling of gases containing sulphur dioxide
IPC: C01B17/56
Filed: 1952-04-02
Abstract: Roasting and combustion gases containing sulphur dioxide are washed and cooled in two or more successive towers by spraying with dilute sulphuric acid continuously circulated in a separate closed circuit for each tower in which the acid fed to the first tower is at about the temperature to which the gases are to be cooled in that tower, said acid being maintained at a concentration such that the desired cooling occurs due to the evaporation of water therefrom without substantial rise in temperature of the acid, there by utilising the sensible heat of the gases to supply the latent heat of vaporisation of the wash liquid which latent heat is reconverted to sensible heat on condensation in the second tower and which sensible heat is removed from the wash liquid in the second tower by passing it during circulation thereof, in contact with cooling surfaces. According to an example a gas at 400 DEG C. containing 6 vols. per cent. of SO2 is cooled to 117 DEG C. by washing in a first tower with 70 per cent strength sulphuric acid.  The arsenic trioxide content of the gas is removed by the acid in the first tower and can be recovered therefrom as a sludge.  Preferably, however, the hot acid is cooled and diluted to deposit the arsenic trioxide before recirculation.  In a subsequent tower or towers the water evaporated in the first tower condenses in the circulating wash liquid of that tower and the heat is removed from the combined condensate and wash liquid at cooling surfaces.  The temperature of the final gas is reduced to 30 DEG C. by the washing liquid in the second or subsequent towers.

Title: Automatic brightness control circuit
IPC: H04N5/59
Filed: 1974-02-26
Abstract: 1431228 Cathode-ray tube circuits SONY CORP 26 Feb 1974 [28 Feb 1973] 8647/74 Heading H4T An automatic brightness control circuit for a (colour) television receiver employs two brightness limiters one of which is responsive only to the occurrence of beam currents representative of a brightness level in excess of a first threshold level but limited in its control effect to occurrences which has a repetition frequency below a first value, the other of the brightness limiters being responsive only to beam currents representative of brightness levels in excess of a second threshold level, higher than the first threshold and limited in its control effect to occurrence repetition frequencies higher than the first value. The first limiter, corresponding to a conventional brightness control limiter, has a time-constant of 50 to 60 m. seconds so that it responds only to brightness changes that are slower than the vertical scanning period whilst the second limiter with a time-constant of about 50 Ásec. is responsive to rapid or momentary brightness changes such as occur when the tuner or channel selector is operated. Thus, in addition to preventing eyestrain due to excessively bright flashes damage to the EHT supply and to the screen of the tube due to the corresponding high beam current is prevented. In one embodiment (Fig. 1) the threshold level of the first limiter is determined by the potential at point 22, a drop in this potential due to an increase in beam current (corresponding to an increase in brightness) operating via a 50 to 60 m. sec. time constant circuit 23 to control (reduce) the gain of the luminance channel 5 and so reduce the beam current. The threshold level of the second limiter is determined by the potential at point 25 which, under normal conditions, is so high that transistor Q1 is non-conductive. When, however, the tuner or channel selector is operated and the brightness of the image suddenly increases to a high level the resulting increase in beam current causes the potential at point 25 to drop below the second threshold level so that Q1 conducts and causes the potential at point 25 to be supplied to grid G1 via a 50 Ásec. time constant circuit, determined mainly by R4, R11 and C3, to reduce the beam current. Alternatively, the potential at point 25 may be supplied via a second time constant circuit 26 and the broken line connection 27 to control the luminance channel. In a second embodiment the transistor Q1 is replaced by a neon tube (Fig. 3, not shown).
