Patent number: 8007687Abstract: An organic solvent which is very useful in paints is made up primarily of n-butyl acetate, n-heptane, methyl ethyl ketone, methyl isobutyl ketone, acetone and a light hydrotreated petroleum distillate. The solvent typically has a closed cup flash point of about 50 to 75° F. The petroleum distillate typically has a boiling range from 230 to 320° F., a closed cup flash point from 35 to 75° F. and a kauri-butanol value not less than 25. A mixture of 8-carbon and 9-carbon hydrocarbons which are typically primarily paraffins or cycloparaffins typically makes up the vast majority of the petroleum distillate.Type: GrantFiled: February 25, 2009Date of Patent: August 30, 2011Inventor: Lawrence A. Boville, Sr.

Patent number: 7997098Abstract: An adsorption heat exchanger (20) is constituted by a fin-and-tube heat exchanger. In the adsorption heat exchanger (20), a first tube column (41), a second tube column (42) and a third tube column (43) are formed in order from upstream to downstream in air flow. The adsorption heat exchanger (20) is formed of a first column part (21) including the first tube column (41), a second column part (22) including the second tube column (42) and a third column part (23) including the third tube column (43). In the adsorption heat exchanger (20), a first adsorption layer (36) is formed on the fins (30) in the first column part (21), a second adsorption layer (37) is formed on the fins (30) in the second column part (22) and a third adsorption layer (38) is formed on the fins (30) in the third column part (23). The amount of adsorbent contained in each adsorption layer increases in order of the first adsorption layer (36), the second adsorption layer (37) and the third adsorption layer (38).Type: GrantFiled: April 25, 2005Date of Patent: August 16, 2011Assignee: Daikin Industries, Ltd.Inventors: Tomohiro Yabu, Shuji Ikegami
