摘要： Controlled release urea-based feed supplements for ruminant animals and controlled release urea-based plant nutrients are comprised of particles or granules comprised in whole or in principal part of urea or having urea at or on the exterior surfaces thereof, and a moisture resistant interpenetrating polymer network coating on the particles comprised of the reaction products of urea and a polyisocyanate, and the reaction products of polyisocyanate, an alkyd resin having at least one double bond in each repeat unit and an oil having at least one double bond, the double bonds being reactive with one another and with themselves. The coated plant nutrients have a substantially linear rate of release of nutrients to the soil over a controlled period of time, e.g., 30 to 120 days. The coated ruminant feed supplements have a substantially linear rate of NPN release in the rumen over a controlled period of time, e.g., 12 to 24 hours. The ratio of nutrients to control agents is high, controlled release is achieved at minimal expense, and the products are economical to use.

摘要： Fresh produce is preserved by coating the exterior surface of the produce with a coating composition comprising an aqueous solution of from about 0.5 to about 4 percent by weight of a cellulose derivative, preferably sodium carboxymethylcellulose, from about 0.05 to about 0.5 percent by weight of konjac, and from about 0.03 to about 0.1 percent by weight of surfactant, preferably dioctyl sodium sulfosuccinate. Optional constituents include antimicrobials, plasticizers and antifoaming agents. The coating composition is effective to control respiratory exchange, i.e., the passage of gases, particularly oxygen, ethylene, carbon dioxide and water vapor, into and out of the produce, thereby to control maturation and ripening of the produce.

摘要： A powder injection molding composition or feedstock is made of 70% or more by weight of a powdered metal or ceramic and 30% or less by weight of a binder system. The binder system contains a sufficient amount of polypropylene or polyethylene to hold the so-called brown preform of the molded metal or ceramic powder together for the sintering step of the injection molding process and a sufficient amount of partially hydrolyzed cold water soluble polyvinyl alcohol water and plasticizer to facilitate molding of the composition into the so- called green preform of the article to be manufactured. The debinding step of the injection molding process for transforming the green preform into the brown preform consists simply of immersing the green preform in water at ambient temperature to dissolve the polyvinyl alcohol. The binder system is nonhazardous, safe, harmless and fully degradable.

摘要： Cold water insoluble, hot water soluble and/or dispersible, disposable films, fabrics and other useful articles of manufacture are formed from a miscible polymeric resin blend comprised of cold water soluble partially hydrolyzed polyvinyl alcohol, cold water insoluble hot water disintegrable aliphatic polyester, and minor proportions of processing and performance aids. The aliphatic polyester has a melt temperature above the normal body temperature of a human (37 degrees C.; 98.6 degrees F.) and is present in the resin blend at a concentration sufficient to constitute the continuous phase of the blend, with the polyvinyl alcohol constituting a discontinuous phase of the blend. The aliphatic polyester thus renders the resin blend, and the partially hydrolyzed polyvinyl alcohol in the blend, cold water insoluble and determines the temperature at which articles formed from the blend will be subject to dissolution in an aqueous bath and subsequent disposal in an environmentally and ecologically sound fashion.
摘要翻译：冷水不溶性，热水溶性和/或可分散的一次性膜，织物和其它有用的制品由可混溶的聚合树脂混合物形成，所述共混物由冷水溶性部分水解的聚乙烯醇，冷水不溶性热水可分解的脂族聚酯和次要比例的加工和性能辅助。脂肪族聚酯具有高于人体正常体温（37℃; 98.6华氏度）的熔体温度，并且以足以构成共混物的连续相的浓度存在于树脂共混物中，与聚乙烯醇构成共混物的不连续相。因此，脂族聚酯使树脂共混物和共混物中的部分水解的聚乙烯醇，冷水不溶，并确定由共混物形成的制品将在水浴中溶解的温度，随后在环境和生态环境中处理声音时尚。

摘要： A medical tube has one or more permanent passive integrated transponders associated therewith that are capable of being located by a detection apparatus which senses the electromagnetic field strength gradient generated by each passive integrated transponder associated with the medical tube and indicates the value of the gradient to the user. In one embodiment, the passive integrated transponder is associated with the distal end of an endotracheal medical tube in a fixed orientation with an electromagnetic field pointing at a preferred angle of no more than 15 degrees to the longitudinal axis of the medical tube. The passive integrated transponder's static electromagnetic field is sensed by the detection apparatus and indicates the location of the distal end of the medical tube within a body.
