  • Patent number: 8729404
    Abstract: A method and apparatus for filling a via with transparent material is presented, including the steps of providing a panel having a via, occluding the via with transparent material in a workable state so that a portion of the occluding material is internal to the via and a portion of the material is external to said via. The external and internal portions are separated so the transparent filler material, when set, forms a smooth and featureless surface. This causes the filled via to have a substantially even and uniform appearance over a wide range of viewing angles when lit.

  • Publication number: 20140121402
    Abstract: Methods and systems for making dibasic esters and/or dibasic acids using metathesis are generally disclosed. In some embodiments, the methods comprise reacting a terminal olefin ester with an internal olefin ester in the presence of a metathesis catalyst to form a dibasic ester and/or dibasic acid. In some embodiments, the terminal olefin ester or the internal olefin ester are derived from a renewable feedstock, such as a natural oil feedstock. In some such embodiments, the natural oil feedstock, or a transesterified derivative thereof, is metathesized to make the terminal olefin ester or the internal olefin ester.

  • Patent number: 8680311
    Abstract: High-pressure electrokinetic (“EK”) pumps comprising a hybrid monolith provide a high surface charge density and a continuous stable skeleton morphology with micrometer-sized through-pores. The hybrid monolith of the subject invention has superior mechanical strength and better stability in comparison to prior art monoliths with equivalent mechanical stability. The surface charge of the hybrid monolith can be modified and/or made stable by the use of different chemical reagents. The chemical reagents and resulting modification to the monolith serves to expand the usefulness of the hybrid monolith to a variety of pumping applications including chip-based systems and other applications where the ability to pump an acidic solution is required.

  • Patent number: 8458018
    Abstract: A consumer is provided with a first asset in return for a promise to earn an agreed to number of points over an agreed to redemption period. The consumer subsequently earns the points by purchasing one or more second assets. At least one of the second assets is different than the first asset. Each purchase has an associated point value, at least one of the point values being different than at least one other point value. An electronic trading system includes a first set of web sites where a consumer can select a first asset it wants to obtain in return for a promise to earn points by making future purchases of one or more second assets. The number of points which the consumer must earn varies as a function of which of the first assets is selected by the consumer. The consumer can fulfill its obligation to earn the stated number of points by purchasing one or more second assets at a second set of web sites. Each of the second assets has an associated point value.

  • Patent number: 8426535
    Abstract: A process is disclosed for the preparation of zinc alkyl chain growth products via a catalyzed chain growth reaction of an alpha-olefin on a zinc alkyl, wherein the chain growth catalyst system employs a group 3-10 transition metal, or a group 3 main group metal, or a lanthanide or actinide complex, and optionally a suitable activator. The products can be further converted into alpha-olefins by olefin displacement of the grown alkyls as alpha-olefins from the zinc alkyl chain growth product, or into primary alcohols, by oxidation of the resulting zinc alkyl chain growth product to form alkoxide compounds, followed by hydrolysis of the alkoxides.

  • Publication number: 20130085288
    Abstract: Methods are provided for refining natural oil feedstocks and producing dibasic esters and/or dibasic acids. The methods comprise reacting a terminal olefin with an internal olefin in the presence of a metathesis catalyst to form a dibasic ester and/or dibasic acid. In certain embodiments, the olefin esters are formed by reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters, separating the olefins from the esters in the metathesized product, and transesterifying the esters in the presence of an alcohol to form a transesterified product having olefin esters.
