  • SINTERED POROUS ELASTOMERIC MATERIAL AND APPLICATION OF THE SAME
    Publication number: 20220323933
    Abstract: A sintered elastomeric material combined with at least one absorbent material and formed into a thin compressible sheet. The material finds particular use in venting or filtering gasses. In specific examples, the elastomeric material may be a thermoplastic elastomer and the absorbent material may be carbon. When an amount of carbon (or any other type of conductive material) included with the elastomeric material is high enough, the material may also find use as a conductive material.

  • Storage bypass driver operation in a highly available computer system
    Patent number: 10871908
    Abstract: A highly available computer system has a primary compute node and a secondary compute node, both of which operate to support at least one similar process using the same instructions and the same information at substantially the same time, and in the event that the secondary compute node generates a read request that is not able to be serviced by cache memory local to it, then the secondary compute node redirects the read request to the primary compute node for servicing.

  • Process for the synthesis of 3-cyano-6-alkoxy-7-nitro-4-quinolones
    Patent number: 6933388
    Abstract: There is provided a process for the preparation of 3-cyano-6-alkoxy-7-nitro-4-quinolone intermediates useful for the preparation of protein tyrosine kinase (PTK) inhibitors which are useful in the treatment of cancer of the formula: wherein R is alkyl(C1-C3) prepared by reacting a substituted anthranilate with N,N-dimethylformamide dimethyacetal to obtain a N,N-dimethylamidine which is condensed with t-butylcyanoacetate to obtain a N-(2-cyano-2-t-butoxycarbonylvinyl)anthranilate, which is hydrolyzed to yield a N-(2-cyano-2-carboxyvinyl)anthranilate followed by decarboxylating to obtain a N-(2-cyano-2-carboxyvinyl)anthranilate followed by cyclizing to obtain a 3-cyano-6-alkoxy-7-nitro-4-quinolone.
