Patent number: 5186979Abstract: An improved method of prevention of adhesion of hot-mix asphalt to dump trucks and other containers or equipment comprises preparing an aqueous dispersion of a vegetable oil and applying the dispersion to the surface of the container before loading the hot-mix asphalt therein. Vegetable oils which are useful as release agents in aqeous dispersion include cottonseed oil, soya oil, rate (canola) oil, peanut oil, corn oil, sunflower oil, palm oil, coconut oil, and palm kernel oil. The oil is emulsified in water, using a suitable emulsifier, preferably a sorbitol base emulsifier, in the amount of 1-5 oz. per gallon of water. The oil and emulsifier are preferably premixed and supplied as a self-emulsifier composition. The resulting emulsion is applied in an amount to provide a thin coating on the wall of the container or equipment.

Patent number: 5133909Abstract: A biologically degradable film is prepared consisting of a synthetic polymer and a biologically degradable polymer. The biologically degradable polymer is divided into small particles in an aqueous suspension by means of enzymes that split and release small molecules from the surface of the biopolymer particles. After achieving desired particle size, an emulsion is formed with vegetable oil and the particles coated with enzyme protein become coated with vegetable oil, which at the same time interrupts the degradation of the biopolymer particles by the enzyme. The coated particles with the oil are separated from the suspension to remove small molecules after which the particles are re-dried and then pulverized. The final film is prepared in a film extruder in which the biopolymer is mixed with the synthetic polymer and possibly other additives that are generally used informing polymer films.Type: GrantFiled: October 4, 1990Date of Patent: July 28, 1992Assignee: Biodata OyInventor: Hannu L.

Patent number: 5089298Abstract: The invention relates to the impregnation of clothing, specifically Battle ress Uniforms (BDUs) used by the U.S. Military, with amylopectin fabric wrinkle inhibitor and permethrin insect/arthropod repellent in combination. In one disclosed embodiment of the invention, BDUs are loaded into a field laundry, are rinsed with clear water at 120 degrees Fahrenheit, and amylopectin is applied at a particular concentration.

Patent number: 4112191Abstract: Lead paint can be extremely hazardous when ingested as a result of ionic lead, produced by the action of stomach acids, being subsequently absorbed into the blood stream. According to this invention, it has been found that certain metal salts of the dithiocarbamates of multifunctional amines are effective precipitants for lead ions. When ingested simultaneously with lead paint they precipitate the lead ion in a substantially insoluble and indigestible form and thereby prevent absorption of lead into the blood stream. The preferred compounds are: zinc pentaerythrityl tetrakis (dithiocarbamate), tetrasodium pentaerythrityl tetrakis (dithiocarbamate), disodium ethylene bis(dithiocarbamate), and zinc ethylene bis(dithiocarbamate). These materials can be included in a digestible coating which can be applied over lead based paints to effectively detoxify the lead paint.Type: GrantFiled: May 31, 1977Date of Patent: September 5, 1978Assignee: United Technologies CorporationInventor: William S.

Patent number: 3940544Abstract: An improved polyethylene terephthalate tire yarn is prepared by applying to the yarn a finish composition comprising a polyalkylene glycol compound having the formulaR--(O--R.sub.1 --O--R.sub.2).sub.n --OHin which R.sub.1 and R.sub.2 are the same or different lower alkylene units such as ethylene, propylene and so forth up to 5 carbon atoms, R is an alkyl group containing 1 to 8 carbon atoms, and n has a value to produce a molecular weight of at least about 300; and about 5 to 35 parts per 100 parts, by weight, of said polyalkylene glycol compound of a triol compound having the formula: ##EQU1## WHEREIN R and R' are independently at each occurrence hydrogen, methyl or ethyl and r, s, and t are integers from 1 to about 20. This method of finishing the tire yarn results in an improved adhesion of the fiber to rubber.Type: GrantFiled: June 28, 1974Date of Patent: February 24, 1976Assignee: Allied Chemical CorporationInventors: Robert Moore Marshall, Kimon Constantine Dardoufas

Patent number: 3937640Abstract: A novel self-adhesive type multi-layer laminated bituminous roofing membrane suitable for the formation of the roofing or waterproofing layer on roofs, floors and the like is provided. It comprises a base sheet of a sheet-like material, one or more bitumen layers coated on all or part of one or both faces of the base sheet, at least one layer of compound bitumen including both bitumen and rubber and/or resin laminated on all or part of the surface of said bitumen-coated layer on the base sheet and at least one release sheet laid over the whole surface of said compound bitumen layer.This roofing membrane is produced by uniting the bitumen-coated base sheet and the compound bitumen-coated release sheet, and can be applied over a substrate in a simple manner, without the step of melting or liquefying bitumen as in the conventional application process.Type: GrantFiled: May 8, 1975Date of Patent: February 10, 1976Assignee: Tajima Roofing Co., Ltd.Inventors: Eiichi Tajima, Kaname Yamamoto, Takayoshi Imai
