    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.

  • Patent number: 8181356
    Abstract: A substrate processing method is arranged to perform a heat process on a substrate with a coating film formed thereon to bake and cure the coating film. At first, the substrate, with the coating film formed thereon, is held at a preparatory temperature lower than a lower limit of temperature for baking and curing the coating film, to adjust distribution of a predetermined component in the coating film. Then, the substrate, with distribution of the predetermined component thus adjusted, is subjected to a heat process at a temperature not lower than the lower limit of temperature.

  • Patent number: 8132629
    Abstract: A sprinkler system and a method for mitigating scaling, microbiological influenced corrosion and oxidative corrosion are disclosed. The system includes a piping network in fluid communication with a source of pressurized water and an air pump. The network is vented to the ambient. The air pump moves initially dry ambient air through the system, either by maintaining a negative or a positive air pressure within the network. The dry air absorbs residual water within the network and exhausts it to the ambient. Rate of air flow through the system is controlled by restrictor elements such as orifices, throttle valves or venturies within the piping network.

  • Patent number: 8112902
    Abstract: A spin or tumble dryer having an air outlet with a moisture sensor is connected to a controller. The moisture sensor determines and stored the measured absolute atmospheric humidity values in the air outlet during operation. Specific characteristic values of the detected moisture can be determined, such as at a point in time and the duration to reach a maximum value or an absolute atmospheric humidity at a specific instant, which can be compared with the values stored in the controller. From this, it is possible to determine the laundry load quantity that is located in the spin dryer, and as a result a program sequence for drying the load can be optimized.

  • Patent number: 8056258
    Abstract: A cord drying apparatus dries cords for forming cord-inserted bands, such as belts and components of tires, such as carcasses. A plurality of cords C unwound from a plurality of reels 1a held in a wheeled creel 1 are passed through guide holes formed in a guide plate 21 and are extended to an insulation head 6. Vertically movable rollers 4 are moved down from their home positions above the cords C to cause the cords C to extend along curved heating surfaces of heating boards 5. The cords C are moved along the heating surfaces of the heating boards 5 to dry the cords C. The cords C can be easily extended along and pressed against the heating surfaces of the heating boards 5. Thus cords C can be changed in a short time and the efficiency of operations for drying cords C by a drying process can be improved.
