Patent number: 6589442Abstract: A stable concentrated dust control composition comprises a mixture of crude tall oil and vegetable oil emulsified in water. The dust control composition is completely organic, non-corrosive, non-flammable, non-toxic, ecologically safe, readily dilutable with water, safe to use, easy to apply to a desired surface and environmentally responsible. The water soluble formula may be designed to penetrate into the surfaces to bind with surface materials to create a dust free durable surface safe to motorists.

Patent number: 6558705Abstract: 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.Type: GrantFiled: December 20, 2000Date of Patent: May 6, 2003Inventor: Robert Neville O'Brien

Patent number: 6303133Abstract: 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.

Patent number: 5344482Abstract: The present invention relates to the use of thiadiazoles of the type ##STR1## in which R.sub.1, R.sub.2 and R.sub.3 =hydrogen,alkyl groups having 1-4 carbon atomssubstituted alkyl groups having 1-4 carbon atoms which are substituted by halogen, carboxyl, hydroxyl or nitro group,an alkoxyCN, halogen, NO.sub.2 orCOOR in which R=H or alkyl groups 1-4 carbon atoms,and the use of synergistic combinations of thiadiazoles with other biocidal substances as biocides for material protection. The compounds according to-the invention, which are distinguished by a broad, biocidal action spectrum, can be used in particular for wood preservation for preventing the destruction of wood by fungi or bacteria, for the biocidal treatment of plastics and as preservatives or disinfectants. The recommended concentrations for use are 0.01 to 15 percent by weight-preferably 0.1-3.0 percent by weight.Type: GrantFiled: September 15, 1993Date of Patent: September 6, 1994Assignee: Witco GmbHInventors: Horst Landsiedel, Dirk Ventur

Patent number: 5196473Abstract: The present invention is directed to substantially dust-free granules. The granules are constituted by a normally dusty inorganic solid material and a water-dispersible nonionic vinyl polymer distributed thereon. The vinyl polymer promotes retention of dust size particles to the granules of the inorganic solid material.Type: GrantFiled: February 28, 1989Date of Patent: March 23, 1993Assignee: Oil-Dri Corporation of AmericaInventors: Rudolph C. Valenta, Leslie C. Giron

Patent number: 5156768Abstract: R12, which contains chlorine, and hydrogen-contributing lubricants react to form acids such as hydrogen chloride and hydrogen fluoride and simultaneously, R12 is converted to R22. Such reactions are undesirable because the acids which form destroy the metallic components of a refrigeration system and cause the breakdown of the lubricants.The present invention provides a compositions for use in compression refrigeration and air-conditioning which substantially reduce the occurrence of the foregoing problem.Type: GrantFiled: April 5, 1991Date of Patent: October 20, 1992Assignee: Allied-Signal Inc.Inventors: Raymond H. P. Thomas, Ruth H. Chen, Kenneth Harris
