Abstract:
L’invention concerne de nouveaux dérivés de la pyrazolo[1,5-a]-1,3,5-triazine et leurs applications dans le domaine thérapeutique tout particulièrement pour le traitement de pathologies impliquant l’activité d’une phosphodiestérase de nucléotides cycliques. Elle concerne également des procédés pour leur préparation et de nouveaux intermédiaires de synthèse.
Abstract:
A method for controlling a drive unit mechanically connected to a reciprocating linear-motion double-acting pump includes the use of speed-regulating control during the phase in which the piston is moving in just one direction, ascent (109) or descent (102), and the use of torque-regulating control immediately after the reversal (107, 114) of the direction of travel. The method is applicable to a control device and to a drive unit mechanically connected to a reciprocating linear-motion double-acting pump.
