    摘要： The present invention relates to a process for the recovery of N-phosphonomethylglycine from an aqueous mixture which contains N-phosphonomethylglycine, ammonium halides, and alkali metal or alkaline earth metal halides and optionally organic impurities in dissolved form, where (a) the pH of the mixture is adjusted to a value in the range from 2 to 8, (b) a separation of the mixture on a selective nanofiltration membrane is performed, a retentate which is richer in N-phosphonomethylglycine and poorer in halides and a permeate which is richer in halides and poorer in N-phosphonomethylglycine being obtained, and (c) the N-phosphonomethylglycine is recovered from the retentate. The process according to the invention makes possible the recovery of the N-phosphonomethylglycine with simultaneous separation of the halide salts.

    摘要： The invention is directed to an air spring (2) having a flexible member wherein a roll-off piston (8) is connected to a flexible member (6) of the air spring (2) via a threaded fastener assembly. The piston volume (8a) is used to provide a softer spring constant in that the piston volume (8a) and the volume (6a) of the flexible member (6) communicate with each other. The sealing ring configured at the lower edge (6c) of the flexible member (6) is clamped tightly between a clamping plate (12) and the sealing surface (8c) of the piston by utilizing a threaded spindle (10) which is sufficiently long. The clamping plate (12) is provided with holes (14). The clamping plate (12) can be configured as a deep-drawn pot provided with several bores (14).
