- Abstract:
When describing unique or local materials, librarians and archivists often create high-quality metadata which then gets stored in collection-specific silos. The systems we use often make reuse difficult, even when the metadata might apply to other materials. I will be talking about a project conducted at the NASA Goddard Library to extract local authorities from one collection of objects in a Fedora repository, then create a localized authority reconciliation service, and finally apply the au…

- Patent Number:
- US 5286698 B2
- Description:
Solid oxide solutions of the formula La.sub.1-x Sr.sub.x CrO.sub.3-.differential. have been found to exhibit surprisingly high specific activity as catalysts for oxidation and hydrogenation reactions. The oxide solutions can be utilized in particulate form or applied as films to the surfaces of refractory substrates. The oxide solution catalysts are expected to be a viable alternative to the noble metal catalysts now used commercially for treatment of combustion chamber exhaust gases to reduc…

- Metal oxide catalysts
- Description
- Solid oxide solutions of the formula La.sub.1-x Sr.sub.x CrO.sub.3-.differential. have been found to exhibit surprisingly high specific activity as catalysts for oxidation and hydrogenation reactions. The oxide solutions can be utilized in particulate form or applied as films to the surfaces of refractory substrates. The oxide solution catalysts are expected to be a viable alternative to the noble metal catalysts now used commercially for treatment of combustion chamber exhaust gases to reduce environmental pollutants.

- Patent Number:
- US 4595532 B2
- Description:
N-Mono or N-disubstituted methyl-2-azetidinones are provided via cyclization of .beta.-hydroxy or .beta.-halo substituted acid sec-amides wherein the amide nitrogen is substituted with a mono- or di-substituted methyl group having activating substituents. Cyclization of .beta.-hydroxy acid amides is mediated by triphenylphosphine-dialkylazodicarboxylate while cyclization of .beta.-halo acid amides is mediated by strong bases e.g. lithium dialkylamides. E.g. Diethyl amino-protected L-serylamin…

Cyclization of .beta.-hydroxy acid amides is mediated by triphenylphosphine-dialkylazodicarboxylate while cyclization of .beta.-halo acid amides is mediated by strong bases e.g. lithium dialkylamides. E.g. Diethyl amino-protected L-serylaminomalonate is cyclized with 200 mole % TPP-diisopropylazodicarboxylate to N-(diethoxycarbonylmethyl)-3-protected-amino-2-azetidinone. The 2-azetidinones provided are useful intermediates.

- Patent Number:
- US 5637795 B2
- Description:
A novel process and apparatus have been contrived for the study of the bit/stabilizer balling phenomenon in the laboratory. The device permits a standard testing procedure using a specially designed bob simulating the drill bit for comparing degrees of balling for different rock formations under different drilling conditions involving variable and controlled parameters like weight-on-bit, revolutions-per-minute (rpm), drilling fluids, etc.

- Patent Number:
- US 4058505 B2
- Description:
Aromatic polyimides with amine end groups are chain-extended (molecular weight increased) by reacting them with aromatic di- or tri- anhydrides. The reaction can either be at a temperature above the melting point of the reactants or in solvents for the reactants. The polyimides can be shaped and formed prior to chain-extending.
