Jet drying

Many modern dishwashers have a container for Jet-Dry cleaning liquid. The use of Jet-Dry eliminates unsightly water stains from clear glassware. This liquid or its equivalent is typically filled once a month or whenever the storage container is empty. The traditional approach to monitor the level of Jet-Dry liquid was to use a little window that showed the liquid level. This, however, was not a very precise indicator of the true level of the liquid left in the container. 

To replace the old-fashioned eye-control method of detecting the level of the liquid, appliance manufacturers now use reed sensors to show when the container for Jet-Dry needs refilling. The reed sensor is mounted underneath, or next to, the liquid container. A floater with an internal permanent magnet is placed in the container and floats on the liquid. If its level falls to a minimum, the floater activates the reed sensor which, in turn, activates a light on the front control panel of the dishwasher, signaling the need to refill the Jet-Dry container. 

The storage container must be free from contamination before use. A solution of strong non-metallic detergent may be used for most applications. After soaking in detergent for a time, rinse the container with tap water, then distilled or deionised water. Dry in an oven at approximately 50°C before use. The use of air-jet drying after application of a volatile solvent, such as acetone, often gives rise to contamination.

A friend of mine told me about his way of cleaning keyboards Remove the electronics and then place the keyboard in a dishwasher in the rinse cyclel Then, let them air dry. I wouldn t recommend this for some of the newer, capacitive keyboards. However, this will actually work for the older keyswitch keyboards (as long as the water isn t hard enough to leave residue inside the key switches or hot enough to melt the keys). Jet-Dry, anyone My friend actually had a part-time business—PM PM (Preventative Maintenance at night) and offered keyboard cleanup services for 20 eachl (In the late 70s this was easy moneyl)...

Polymeric nanofibers can be made using the electrospinning process which has been described [20-35]. Electrospiiming, Figure 1 uses a high electric field to draw a polymer solution from tip of a capillary toward a collector. A voltage is applied to the polymer solution which causes a jet of the solution to be drawn toward a grounded collector. The fine jets dry to form polymeric fibers which can be collected as a web.

Often, the jet dries too rapidly to allow extensive crystallization, but some orientation can still result. With PEO electrospun from a 10wt% water solution. X-ray studies (WAXD pattern) shows broad diffused peaks as opposed to characteristic powder patterns for the polymer (Deitzel et al. 2001b, 2001c). The effect of macromolecular strain on the secondary structure of the nanofiber is particularly important in processing biological polymers. Changes in secondary and tertiary stmcture in biopolymers can result in corresponding loss of activity. Nylon-6 and nylon-12 electrospun from 15 wt%...
