Title: Fixed-bed reactor and process for producing 2,2-bis(4-hydroxyphenyl)propane with the same
Inventor: YOSHITOMI KAZUYUKI
IPC: C07C37/20
Filed: 2006-10-16
Abstract: A fixed-bed reactor having an ion-exchange resin catalyst layer. The reactor has a liquid collection/discharge mechanism in a lower part thereof, and a liquid reaction mixture yielded is discharged through the liquid collection/discharge mechanism. In the fixed-bed reactor, the liquid collection/discharge mechanism comprises: inflow pipes which have, at the front ends thereof, a screen or perforated board for enabling the liquid reaction mixture to pass therethrough and which have lengths regulated so that the ends thereof conform to the curved bottom surface of the fixed-bed reactor; liquid collection pipes which have been connected to the back ends of the inflow pipes and serve to collect the liquid reaction mixture which has passed through the inflow pipes; and a liquid discharge pipe which has been connected to the liquid collection pipes and serves to discharge the liquid reaction mixture outside the system. Due to the constitution, the liquid reaction mixture passing through the packed-catalyst layer flows evenly, and the lower part of the reactor can be prevented from having a space not filled with the catalyst. Thus, the fixed-bed reactor has an improved product yield per unit reactor capacity and unit time. Also provided is a process for producing bisphenol A in which the reactor is used.

Title: Power supply testing architecture
Inventor: KIM JIN KI
IPC: G01R31/40
Filed: 2007-03-08
Abstract: A power supply testing architecture for embedded sub-systems is described, where each embedded sub-system can have at least one testable internal voltage supply. A plurality of embedded sub-systems are organized into groups, where each group of sub-systems shares a common voltage test line connected to the internal voltage supplies of the sub-systems. Accordingly, the collective internal voltages of each group can be tested in parallel. A power control signal can disable the internal voltage supply of all the sub-systems to allow application of an external power to the common voltage test lines. Alternately, the sub-systems in each group can be tested sequentially, such that each enabled sub-system of the group has dedicated access to its common voltage test line. In such a scheme, dedicated power control signals are used to independently disable each sub-system of the groups. ® KIPO & WIPO 2009

Title: Fouling resistant membranes formed with polyacrylonitrile graft copolymers
Inventor: MAYES ANNE M
IPC: B01D71/82
Filed: 2007-04-10
Abstract: The present application is generally directed towards polyacrylonitrile-(PAN-) based, amphophilic graft copolymers, for example, for the production of membranes for liquid filtration. In one aspect, the present invention provides systems and methods for preparing high flux, fouling resistant nanofiltration membranes whose pore size can be readily tuned. In some cases, microphase separation of a graft copolymer comprising a backbone comprising polyacrylonitrile (PAN) and hydrophilic side-chains is used. In some cases, nanochannels of tunable width are formed, which may give the membrane permselective properties and/or anti-fouling character. In some cases, a copoylmer may be used as an additive in the immersion precipitation casting of ultrafiltration or microfiltration membranes. In certain instances, the additive can segregate to the membrane exterior and/or pore surfaces, e.g., due to favorable interactions between the hydrophilic side chains and the surrounding environment, which may create a surface that resists fouling, e.g., by biological molecules.
