Abstract: Disclosed are radiation treatment systems with enhanced control architectures that enable more complex treatment plans to be implemented, and radiation treatment systems with enhanced resistance to the effect of neutrons. An exemplary control architectures comprises: a digital packet network; a supervisor electrically coupled to the digital packet network and having a treatment plan; and a plurality of nodes, each node coupled to digital packet network and controlling one or more treatment-related components of the radiation treatment system; and wherein the supervisor periodically communicates control orders to the nodes over the digital packet network.

Abstract: The invention provides additive mixtures comprising A) at least one terpolymer of ethylene, propene and at least one ethylenically unsaturated ester, which i) contains from 6.0 to 12.0 mol % of structural units derived from at least one ethylenically unsaturated ester having a C1- to C3-alkyl radical, ii) contains from 0.5 to 4.0 methyl groups derived from propene per 100 aliphatic carbon atoms, iii) has fewer than 8.0 methyl groups stemming from chain ends per 100 CH2 groups, and B) from 0.5 to 20 parts by weight, based on A), of at least one further component which is effective as a cold additive for mineral oils and is selected from B1) copolymers of ethylene and ethylenically unsaturated compounds whose content of ethylenically unsaturated compounds is at least 2 mol % higher than the content of ethylenically unsaturated esters in the terpolymer defined under A), B2) comb polymers, and B3) mixtures of B1) and B2), and also their use as a cold additive for middle distillates.
