What we claim is:
1. An evaporative stand-alone cooling device comprising:
a housing having a multiple of open vertical sides including wettable evaporative pads placed in each of said openings of said vertical open sides;
said open sides having at their tops horizontal support braces in the form of downwardly open channels;
means for delivering water to each top of said evaporative pads to flow downwardly through said pads by way of gravity;
said means for delivering water is located within said downwardly open channels of said support braces;
a sump is located at the bottom of said housing to collect excess water therein from said evaporative pads.
a pump is placed in said sump to deliver water to said means for delivering water located in said downwardly open channels including a float located in said sump to detect a minimum level of water in said sump to stop said pump;
said housing further includes a centrifugal blower being driven by a first electric motor, said blower being mounted in said housing so as to create a positive pressure of vertically flowing air while at the same time creating a negative pressure of laterally flowing air through said evaporate pads;
said housing further includes a cover at its top having an opening therein to accommodate said vertically flowing air;
a rotatable spout is placed over said opening in said cover including means for oscillating said spout in a multiple of substantially horizontal directions.
2. The evaporative cooling device of claim 1, wherein said means for oscillating said spout includes a second electric motor driving an eccentrically rotating block which in turn is driving a linkage connected to said spout.
3. The evaporative cooling device of claim 1, wherein said first electric motor is a direct drive motor.
4. The evaporative cooling device of claim 1, wherein said first electric motor is a belt drive motor.
5. The evaporative cooling device of claim 1 including a water connection in said sump for delivering water into said sump.
6. The evaporative cooling device of claim 5, wherein said water connection is connected to a water valve device including a float to detect a maximum of a water level in said sump to shut off said water valve.
7. The evaporative cooling device of claim 1, wherein a drainage plug is provided in the bottom of said sump.
8. The evaporative cooling device of claim 1, wherein a movable access door is provided in one of said evaporative pads to be able to gain access to the interior of said housing.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A key sheet in which a resin film, provided with a mirror-like evaporation deposit layer on a part or all of the back, and with a colored layer is further on its back, is integrated with the top face side of a button made of resin, wherein the optical concentration of the laminated portion of resin film and evaporation deposit layer is 0.35 to 0.85.
2. The key sheet of claim 1, wherein the colored layer colored has a plurality of colors
