  • Publication number: 20180106106
    Abstract: The invention relates to an operating device (1) for a screen, comprising: a first operating mechanism with a first operating element (7) which is connected to a first movement transfer element connected by means of a first transmission to a drive element (60) for a screen shaft. The first operating mechanism is configured to convert a linear movement of the first operating element to a rotational movement of the drive element for operating the screen shaft in a first rotational direction (R). The operating device (1) further comprises a second operating mechanism comprising a second operating element (8) which is connected to a second movement transfer element connected by means of a second transmission to the drive element (60). The second operating mechanism is configured to convert a linear movement of the second operating element to a rotational movement of the drive element for operating the screen shaft in a second rotational direction (L) opposite to the first rotational direction.

  • Publication number: 20130326903
    Abstract: The invention relates to a process for dehydrating a water-containing medium, said medium being a pressurized gas having a pressure of at least 0.5 MPa, said process comprising:—contacting the water-containing medium with a dry ionic liquid choline salt to dehydrate the water-containing medium; and—separating a dehydrated medium from the hydrated ionic liquid choline salt. Ionic liquid choline salts offer the advantage that they can be regenerated very easily as they are surprisingly heat-stable. Furthermore, these liquid choline salts offer the advantage that they are non-toxic and largely inert. Thus, these ionic liquid choline salts can suitably be used to dehydrate water-containing media that are subsequently employed in the production of foodstuffs, beverages, nutritional formulations, pharmaceutical preparations etc.
