    摘要: Ethylene amines are extracted from a solution containing at least 10 wt.% of NaCl and a maximum of 5 wt.% of NaOH using a water-miscible solvent with a boiling point below 105°C, which solvent is immiscible with an aqueous salt solution. Such extraction allows for an economically favourable process for the recovery of ethylene amines to be obtained that will cause no environmental problems.

    摘要: Apparatus for withdrawing blood from a donor, comprising a blood line (5) forming part of the blood flow conduit means for conducting the blood withdrawn from the donor. To the blood line (5) there are further connected a pressure transducer (6) and a blood pump (7). The pressure transducer (6) has a visual display (10) for reading the actual pressure P A at the exit of the needle (2). Along a signal line (11), the transducer (6) supplies to a control device (8) an electric signal representing the pressure P A . Moreover, the blood pump (7) co-operates with means for measuring the blood flow rate of the pump. The electric signal representing the measured blood flow rate is supplied to the control device (8) by means of a signal line (13). Said control device serves to control the flow rate of the blood pump (7) in response to the actual values of the pressure P A and the blood flow rate Q. The control device (8) operates according to a certain control algorithm in such a way that during the withdrawal procedure the pump (7) withdraws an optimal amount of blood per unit time from the donor.

    摘要: The present invention pertains to a dispersion in an organic liquid of a (meth)acrylate based addition polymer stabilized by a graft copolymer of a polybutadiene with particular monomer components grafted thereon. The pre­sent invention also pertains to a coating composition based upon such dispersion and to a process of coating a substrate with the coating com­position. Finally, the present invention relates to a process for the pre­paration of the stabilizer of the disperion.
