Title: Improvements in recovery of sulphur dioxide from gases
IPC: C01B17/60
Filed: 1936-12-24
Abstract: In recovering sulphur dioxide from gases by absorbing the sulphur dioxide in an aqueous salt solution and recovering the absorbed sulphur dioxide and regenerating the salt by heating, there is dissolved in the solution an appreciable quantity of a free weak acid, this quantity being additional to acid formed or liberated by the absorbed sulphur dioxide or formed by the hydrolysis of the salt. The salt employed may be ammonium sulphite or the salt of a weak acid, e.g. the alkali metal or ammonium salts of acetic, benzoic, chloracetic, citric, fumaric, lactic, phosphoric, phthalic, salicylic, sulphanilic, or tartaric acids.  The free weak acids employed may be those specified above. The free weak acid may be the same as or different from that forming the salt.  When the acid forming the salt is water-insoluble, a different water-soluble free acid should be employed.  Preferably, both the acid present as a salt and that present in the free state should be stable and substantially non-volatile at the boiling temperature of the solution.  The Specification as open to inspection under Sect. 91 comprises also the employment of a solution containing tri-ammonium citrate and citric acid in the proportions of 445 to 189 by weight.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to frequency detectors
IPC: H04L27/156
Filed: 1969-07-16
Abstract: 1,270,571. Frequency discrimiriater. DIGITRONICS CORP. 16 July, 1969, No. 35907/69. Heading H3A. A frequency shift demodulator comprises: means 10, Fig. 1, for generating at a pulse for each cycle of a signal from source 8, which pulses are fed to an integrator C2; means 24 for reducing the value stored in the integrator at a uniform rate and for preventing the stored value passing upper and lower limits; and means L6 for switching the level of the output signal whenever the stored value changes by a predetermined amount. As shown in Fig. 1 the pulses produced by zero-crossing detector 10 trigger monostable circuits 12, 14 to produce constant width pulses having the frequency of the incoming signal. These pulses are integrated by capacitor C2 to give a voltage at one of two levels depending on whether the frequency corresponds to a mark or a space. This voltage is then passed to a bistable 34 to cause it to take up a corresponding stable state. In order to avoid any errors due to the capacitor charge being at an intermediate value, feedback path L6 from the bi-stable ensures that the capacitor is clamped to one or other of its two levels depending on the state of the bi-stable. In a second embodiment, Fig. 2, the frequency of the input signal is determined by the number of stages of a shift register 112 which are set to their "1" state when it is triggered by clock pulses from source 112A. The outputs from each stage are summed at point 114J, so that the potential at that point is proportional to frequency and corresponds to the voltage on capacitor C2 in the first embodiment. Feedback depending on the state of bi-stable 115 is similarly provided.
