Abstract: A multi-circulation heat recovery steam generator (HRSG) for steam assisted gravity drainage (SAGD)/Enhanced Oil Recovery (EOR) processes comprises a steam drum internally partitioned to provide a clean side and a dirty side. The clean side downcomer pipe supplies water to one or more generating banks as part of a clean circuit located in a high heat flux zone of the boiler. Boiler water is fed from the clean side of the drum to the dirty side of the drum via natural head differential. Water is then fed through a corresponding downcomer to a dirty generating bank, which is located in a low heat flux zone of the boiler.

Abstract: A CAD model of a component is designed by means of a CAD system that modifies the shape of the design of the component represented by the CAD model by means of templates held in a database of templates. The templates include machining data concerning the machining actions necessary to effect the alteration, represented by the template, of the shape of a work-piece. The CAD system outputs a computer model of the component comprising not only part geometry data concerning the shape of the component but also machining geometry data concerning the machining actions necessary for manufacturing from a work-piece a component having a shape in accordance with the outputted model of the component. This outputted computer model is then converted into an NC (numeric control) program by means of an NC program conversion module, by extracting NC code sequences from a database, the NC code sequences extracted corresponding to the templates of the UDF library used to design the shape of the CAD model.

Abstract: a process for the manufacture of a foamed thermoplastic aromatic polyethersulphone comprising heating a solid thermoplastic composition comprising an aromatic polyethersulphone which is not in admixture with another type of thermoplastic polymer, said composition containing 0.25 to 20% by weight of an absorbed volatile liquid selected from water, acetone, ethyl acetate, methyl ethyl ketone, methylene chloride and chloroform, to a temperature above (Tg-50).degree. C where Tg is the glass/rubber transition temperature of the thermoplastic polyethersulphone.Preferably the thermoplastic composition contains 0.5 to 20% and particularly 1 to 20% by weight, of the absorbed volatile liquid.The solid thermoplastic composition may be in the form of a powder or granules so as to produce a foamed puff-ball type of structure or it may be in the form of a shaped article such as a sheet, film, coating, moulding or extrusion so as to produce a foamed shaped article.
