Abstract:
When a user programme is executed, the invention calls for the function code associated with an output signal (A1 to A4), and the function parameters associated with this function code, to be read. Per function parameter, depending whether the parameter refers to an input signal (E1 to E4) or to another instruction (B5), either the input signal (E1 to E4) is temporarily stored or branched off to the other instruction (B1 to B5), and its function code and function parameter executed. Generation of the user programme is carried out in analogous fashions. In addition, however, storage or identification as valid of the user programme is prevented if not all of the function parameters for all the instructions (B1 to B5) for at least one output signal (A1 to A4) have been input.
Abstract:
The invention concerns a continuous process for preparing expandible styrene polymers by polymerizing styrene in the presence of expanding agents in three stages: a) preparing a solution of polystyrene in styrene; b) dispersing the solution in an aqueous phase; and c) continuously polymerizing out the prepolymer in an aqueous suspension.
Abstract:
A process is disclosed for continuously producing expandable styrene polymers by polymerising styrene in the presence of expanding agents in three steps: (a) prepolymerising styrene in the mass; (b) dispersing the prepolymer in an aqueous phase; and (c) polymerising the prepolymer in an aqueous suspension.
Abstract:
The invention relates to a method for producing an aqueous powder-paint dispersion, which is characterized in that a liquid molten mass containing binders and cross-linking agents, and possibly catalysts, auxiliary substances and other additives such as degassing agents, UV absorbers, radical traps and/or antioxidants, is mixed and placed into an emulsifier, preferably together with water and stabilisers, and in that the resulting emulsion is cooled and filtered.
Abstract:
The invention concerns a method of producing multi-layer medicaments in solid form for oral or rectal administration. At least two substances, which each comprise a thermoplastic, pharmacologically acceptable polymer binder which is soluble or can swell in a physiological environment, at least one of the substances comprising a pharmaceutical active substance, are coextruded and the coextruded multi-layer material is shaped to form the desired medicament.
