Title: Claus process control system - using hydrogen sulphide and sulphur dioxide concns to control air supply
IPC: C01B17/04
Filed: 1974-10-15
Abstract: In an improved Claus process control scheme the rate of supply of oxygen to a hydrogen sulphide burning face is controlled so that at a sample point, the concentration of hydrogen sulphide is twice the concentration of produced sulphur dioxide. Two titrators are used to analyse scrubbed and unscrubbed samples to give outputs indicative of the hydrogen sulphide concentration and the total sulphur concentration respectively.

Patent FR-2333558-A1 (FR)
Title: Electrochemical purification of exhaust gases - esp. removal of nitrogen oxides
IPC: B01D53/32
Filed: 1976-12-06
Abstract: Purification of exhaust gases, esp. removal of NOx, is carried out electrochemically by contacting the gases with the cathode and/or the anode of an electrolytic cell with a liquid electrolyte. The cathode is made from a metal or alloy more electropositive than hydrogen, or from a porous inert material such as carbon or iron oxide. The anode is made from a metal or alloy less electropositive than hydrogen, or from an inert material, such as carbon or iron oxide; it can be executed in the form of a gas-diffusion electrode. The exhaust gases may be recycled, if one passage is insufficient to attain the required purity. A gas pretreatment chamber can be opt. provided pref. adjacent to the cathode, where NOx is decomposed in such a manner that NO predominates; it is then electrochemically converted to N2 and H2O. The minor quantity of NO2 is converted to NO3- and NO2-. The removal of nitrogen oxides (NOx) from exhaust gases is carried out very effectively at room temp. or an elevated temp. The method can be applied to purificn. processes other than the NOx removal, or for recovery of valuable substances from gas mixts. Oxidn. or redn. reactions can be preformed by suitably changing the polarity of the cell.

Title: Transparent moisture-impermeable lining for interior of buildings - comprises acrylic! resin and transparent (in)organic fibres
IPC: C09D7/62
Filed: 1977-06-21
Abstract: The lining comprises a colourless synthetic resin in the bulk of which is a reinforcement comprising strands of (in)organic yarns. The yarns are transparent or translucent and UV resistant and are uniformly distributed in the resin. They are 5-20 mu in dia. and 1.5 mm in length. The resin is pref. an acrylic resin and the fibres are pref. glass fibres which have been pretreated with a wetting agent to facilitate their swelling and the penetration of the resin between the yarns. The lining is applied by spraying a mixt. of the resin and the prewetted fibres. The process is quicker than prior art. methods and the lining has better mechanical strength than whe using a fabric as reinforcing agent. It also has better appearance as the fibres are not visible from a distance.
