  • Patent number: 6558705
    Abstract: Parent disclosure, now U.S. Pat. No. 6,303,133 B1, taught a calcium hydroxide containing evaporation retardant having particles that mutually repel one another because of water-induced ionization. Calcium hydroxide makes the retardant unsuitable for treating overly alkaline agricultural soil, and to substitute plain calcium sulfate for calcium hydroxide would degrade the particle repulsion effect. Substitutable acidified gypsum is made by absorbing about 5 milliliters sulfuric acid per 300 grams calcium sulfate. Blending unemulsified detergent range alcohol in a parts by weight ratio of about one-to-ten with the acidified gypsum produces a soil treatment product for suppressing evaporation of water from treated soil without impairing water infiltration into the same soil.

After addition of thickener, the follower is made depressurized preferably at 0.2 atm or lower. Simultaneous heating and stirring are preferable. When the ink follower is solely debubbled in advance, fine bubbles contained in particulate silica, clay thickener, etc. can be very highly removed even if the centrifugal debubbling is not so strong and there is no bad affection to the writing property of the pen. It is also possible that, after adding the thickener, a centrifugal force greater than or equal to 200-fold of the gravitational acceleration is applied to debubble.

  • Patent number: 6303133
    Abstract: The invention pertains to enhancing the dispersion on the surface of a still or moving body of a polar liquid, such as water, of particles of a powder of the composition essentially comprising a monolayer-forming constituent, such as hexadecanol or octadecanol or a blend thereof, together with a high proportion of a soluble or sparingly soluble alkaline earth metal hydroxide, more particularly about five times the monolayer-forming constituent's weight when the hydroxide constituent is—as preferred for potable water evaporation reduction—calcium hydroxide procured as inexpensive pre-powdered agricultural hydrated lime. A melt-processing manner of producing the composition is described. When particles of the composition contact the body of water, so long as lime remains present in any floating particles, they will be individually positively charged, resulting in their repulsion from one another. This enhanced dispersal effect is due to the ionization of the calcium hydroxide.

  • Patent number: RE32991
    Abstract: The disclosed wound dressings have a drug dispersed throughout a polyurethane matrix that is the reaction product of: (A) An isocyante terminated prepolymer formed by reaction of isophorone diisocyanate and a marcoglycol and (B) a monomer containing hydroxyl and vinyl groups. The reaction product is a vinyl terminated polyurethane oligomer which is liquid at room temperature and which may be readily admixed with a pharmacoactive substance and a photosensitizer, formed into a film and cured by exposure to UV light without release of heat.In the most preferred embodiments the foregoing oligomer is codissolved in an organic solvent with a polyurethane polymer which is the reaction product of:dicyclohexyl methane diisocyanate;a polytetramethylene ether polyol having a molecular weight in the range of 1000-3000 daltons; and1,4-butane diol.That solution is then admixed with the pharmacoactive agent, formed into a film and cured.
