  • Patent number: 7496784
    Abstract: A method is provided to protect against ill-behaved microcode by balancing between an actual occurrence of a hardware problem and a microcode bug setting a flag appearing as a hardware problem. In this method, the error recovery is performed only on a single piece of hardware and no further error recovery action is taken on other pieces of similar hardware. The approach addresses the problem by treating a hit on one card as a hardware problem, but as a bug on subsequent cards. The invention keeps track of whether or not the same event has occurred on the same type of hardware so not to take action on more than one instance of the hardware. Subsequent hits on another instance of the hardware will not trigger the hardware related recovery on additional hardware.

  • Publication number: 20080134883
    Abstract: In order to synthesize semi-interpenetrating polymer networks (semi-IPNs) with molecular sieve characteristics, polyetherimide/bismaleimide (PEI/BMI) chromophore composites were made through sol-gel technique. A tunable and compatible chemical structure with fine morphology was obtained through in situ controlled sol-gel polymerization, crosslinking, chemical modification and membrane fabrication. The novel semi-IPN, synthesized and assembled by using ethanol as polar protic modifier and pore former, had a superior structure and morphology suitable for making gas separation membranes. These semi-IPN membranes gave fifteen times higher gas flux without significant decrease in their gas permselectivity than membranes prepared from pure PEL The chemical structures of these novel semi-IPNs were characterized by using FTIR, XPS and SEM.

  • Patent number: 6989097
    Abstract: The invention disclosed relates to feed spacers used in various filtration membrane modules, such as in spiral wound membranes, used in cross-flow filtration. Such spacers have an influence in promoting the mixing between the bulk of the fluid and the fluid element adjacent to the membrane surface so as to keep the membrane surface relatively clean. To optimize these properties, novel spacer designs are disclosed having a plurality of rows of elongated strands, the strands in each row being arranged substantially in parallel to one another, with adjacent rows being attached and disposed at an angle to one another, the strands of at least one row when viewed in cross-section having a central portion of a width smaller than the width of its extremities. Novel membrane modules incorporating such feed spacers are also disclosed.
