  • Patent number: 6541518
    Abstract: Derivatives of simple carboxylic acids, particularly trisodium citrate and other citrate salts are effective agents for enhancing the production of blood clotting factors. Addition of citrate to plasma, especially at concentrations between 2 and 10% by weight, does not appreciably denature labile proteins. However, citrate is effective in inactivating or inhibiting a variety of pathogenic microorganisms. Further, the added citrate potentiates or enhances the killing of microorganisms by heat treatment. The added citrate causes a dramatic increase in the weight of cryoprecipitate that can be produced from plasma by the usual procedures. The majority of significant clotting factors are greatly concentrated in the resulting cryoprecipitate. Increasing the amount of citrate in blood bags so that the final concentration will be at least 2% by weight results in plasma that provides improved platelet concentrates because added citrate helps eliminate contaminating microorganisms.

  • Patent number: 6541524
    Abstract: Facilities to convert natural gas into syncrude often are located at remote sites. At these sites and in their surrounding communities there exists demand for salable products: gasoline, distillate fuels, solvents, lubricants, etc. While it would be possible to produce these products from syncrude, the construction of such production facilities would be very expensive, and their operation would be difficult at the remote site. Fischer-Tropsch syncrude will be waxy and will also contain volatile components, complicating the shipping of both Fischer-Tropsch products from remote production sites to developed sites and salable products from developed sites to remote sites. This invention describes a safe process to both transport Fischer-Tropsch syncrude from the remote site to the developed site and supply salable products from the developed site to the remote site.

  • Patent number: 6541526
    Abstract: Mechanical/chemical method and composition for de-vulcanization of rubber maintains the macromolecules, renders sulfur passive for later re-vulcanization, is cost effective, environmentally friendly and produces high quality de-vulcanized rubber to replace virgin rubber. Waste rubber is shredded, crushed and metal-removed. Modifying composition is added as the particles of shredded waste rubber are poured between two rollers that further crush the particles. The modifying composition is a mixture of (1) a proton donor that selectively breaks the sulfur bonds and renders the sulfur passive, (2) a metal oxide and (3) an organic acid that build new bonds between macromolecules for later re-vulcanization, (4) an inhibitor that prevents re-attachment of sulfur radicals with each other before the proton donor attaches itself to the sulfur and (5) a friction agent that prevents sliding of the waste rubber between the rollers. The particles are subjected to at least ten sets of rollers.

  • Patent number: 6541531
    Abstract: This invention relates to an improved dosing assembly (valve/feed line/liquid collecting vessel) which permits nearly immediate response time to an actuator signal. Such an assembly is used for the controlled introduction of any liquid through a valve into a collecting vessel. In particular, the inventive assembly exhibits substantially no leakage from the feed line into the liquid collecting vessel when the valve is closed and an instantaneous introduction of the feed line liquid into the liquid collecting vessel upon opening of the valve, both when a liquid possessing a surface tension of about 50 dynes/cm2 is used as the measurement standard. This assembly is particularly and preferably suited for injecting colorants into reactants for the production of polyurethane slabstock foam and permits a substantial reduction in foam waste due to low colorations during an on/off cycle.

  • Patent number: 6541532
    Abstract: New, useful and surprisingly effective antiscorch compositions for utilization within polyurethane foam production methods which utilize very popular tertiary amine catalysts are provided. Such compositions require the presence of nominal yet effective amounts of organic cyclic ester materials. The ring systems of such materials appear to open during exposure to heat (during the curing process) and release carboxylic acids into the curing formulation. The tertiary amines become quenched by the carboxylic acids and thus do not exhibit heat destabilization. The resultant foams exhibit extremely low, if no, areas of excessive heating (i.e., scorch) and thus are substantially uniformly colored throughout. The processes and resultant foams are also contemplated within this invention.

  • Patent number: 6541537
    Abstract: A compound and a method of forming a photopolymerizable acrylated glycidyl acrylic terpolymer resin compound is disclosed. The polymeric resin may be formed in a two-step process. A photopolymerizable acrylic hybrid polymer is suitable for forming films having glass transition temperatures from about −55 degrees C. to about 110 degrees C. A non-aromatic photopolymerizable acrylate polymer may be formed by combining, in a first step, a reactive source of epoxide ion groups. In a second step, the glycidyl acrylic terpolymer formed in the first step is reacted with a catalyst and a source of unsaturated acid or anhydride to form an acrylate polymer. A ring opening reaction is employed such that an acid or an anhydride containing a conjugated double bond forms an acrylated acrylic, an acrylated fluorinated acrylic, an acrylated silonted acrylic, or an acrylated halogenated grafted acrylic. The cure process is initiated with specific UV or visible light promotors and/or with a UV or visible light source.
