A process for the preparation of C.sub.14 -C.sub.18 -alkylphosphocholines by reacting an n-alkanol with a chain length of C.sub.14 -C.sub.18 with phosphorus oxychloride in an inert solvent or also without solvent in the presence or absence of a basic substance in a single vessel process and subsequent reaction of the reaction product in an inert solvent with a choline salt in the presence of a basic substance to form phosphoric acid diester chloride, subsequent hydrolysis and isolation of alkylphosphocholine as well as optionally purification using a mixed-bed ion exchanger or in successive steps with an acid ion exchanger and a basic ion exchanger.

摘要:
A telecommunity alarm system having a plurality of security surveillance modems that can be connected to a telecommunication network via an analog or digital subscriber terminal port, the security surveillance modems forming a group of a predetermined size. The security surveillance modems each have a first memory for storing telephone numbers of the other modems in the group, a second memory for identifying the particular modem and a programmable control unit. The modems are designed to dial automatically, in the event of an alarm, the other security surveillance modems belonging to the group and signal the alarm status.
摘要:
One or several vibration dampers of a vehicle suspension have a damping force arrangement wherein a control signal is computed within the actuating range in accordance with a standard control method for adjusting the damper characteristic. The drive of a damper adjustable in accordance with this invention is so improved that body movements (notwithstanding a harder adjusted damping for critical driving situations) are substantially suppressed as early as possible. In specific driving situations, the adjusting range of the damper force is changed in that the upper limit of the adjusting range is raised or lowered and/or the lower limit of the adjusting range is raised or lowered. A soft damper setting takes place preferably in dependence upon signals which announce or display a change of the vehicle longitudinal deceleration or vehicle transverse acceleration.
