Title: Plastics bags with valves made from continuous sheet - valves are not in line with folds thus ensuring symmetrical reeling
IPC: B31B160/10
Filed: 1974-12-06
Abstract: A method of making plastic bags with lateral folds and valves utilises as starting material a flat plastics sheet to which the valve seats are fitted before the sheet is bent over so that its edges overlap to form a tube; while the sheet is still flat, slits are formed in it near to one edge, the valve seats are then placed over these slits with their outer edges stitched to the outer edge of the fold to be formed in the tube later, and are then welded by a seam situated between the transverse or longitudinal weld of the tube and the opening slit itself. Pref., the tube has transverse lines of perforations between successive transverse seams. The entire train of bags are pref. rolled up while still in the form of a tube. By locating the valves not at the folded joint, the superimposition of extra thickness at this joint, which normally results to a conical or distorted rolled up tube, is avoided. Instead, the tube rolls up to a generally cylindrical shape.

Title: Ammonia removal from ammoniacal vapours - by partial combustion followed by total combustion to minimise nitrogen oxides
IPC: F23G7/06
Filed: 1975-02-04
Abstract: The removal of NH3 from ammoniacal vapours obtd. by steam stripping of NH3 absorption solns. (esp. those used in coke-oven gas purificn.) is carried out by (a) subjecting the vapours to partial combustion at 950-1150 degrees C with a substoichiometric amt. of O2 and then (b) subjecting the prod. to total combustion with excess O2 at 950-1050 degrees C, the optimum temp. in stage (b) being adjusted by recycle of effluent gas and the sensible heat of the combustion gases being utilised to generate steam. The process minimises the NOx content of the effluent gas emitted into the atmosphere; the NOx content is only about 30% of that in effluent gases produced by simple combustion with excess O2. In stage (a) the vapours are pref. burnt together with added fuel (e.g. coke-oven gas). The amts. of O2 used are pref. 90-99.9% of the stoichiometric amt. in stage (a) and 100.1-110% of the stoichiometric amt. in stage (b). The recycled effluent gas is pref. divided into several streams, which are introduced at different points into the combustion chamber.
