Title: Reducing emission of sulphur cpds in waste gases - esp from incinerators for "black liquor" in cellulose industry
Inventor: PATERSON THOMAS RANKINE
IPC: B01D53/50
Filed: 1974-07-04
Abstract: In a process for reducing the emission of gaseous S-cpds. from a furnace in which the cpds. are subjected to an incineration process, the supply of oxygen to the combustion process is so controlled that the cpds. are oxidised to SO2 and SO3 or H2SO4, whilst a metal carbonate is injected into the flue gases to react with the SO3 or H2SO4 to form solid metal sulphate which is sepd. from the waste gas as a solid. The technique overcomes the problems caused by the difficulty of accurate controlling the supply of air, i.e. corrosion by strongly acid as when too much air is supplied, and emission of odorous S-cpds. when too little air is supplied.

Title: Flexible trimaran sailing boat - with flexible spars to prevent outriggers being submerged due to wind pressure on sail
Inventor: MOLL HANS HEINRICH DR ING
IPC: B63B1/14
Filed: 1974-07-20
Abstract: Trimaran sailing boats, in which a main central hull is stabilised by two outrigger hulls, are easily capsized if a squall forces the lee outrigger under the water. the invention provides special joining spars which have a flexible section to give if the main hull heels over too far. This reduces the effective area of sail instantly and maintains the stability of the craft. The other outrigger is still lifted out of the water. The joint is either fibre glass or sprung, and the joint line runs at an angle towards the main hull bows, so that if an outrigger is lifted out of the water then its stern trails down to prevent it submerging if suddenly dropped back.
