  • Patent number: 9940379
    Abstract: A system for accelerating database transaction processing by controlling data replication is provided. The system includes a first control unit configured to manage a first storage device and at least one second control unit configured to manage a second storage device. The first control unit writes first data to the first storage device and sends the first data to the second control unit in response to receiving from a host a first write command including the first data. The first control unit writes second data to the first storage device without sending the second data to the second control unit in response to receiving from the host a second write command. The second control unit writes the first data to the second storage device in response to receiving the first data. The second control unit writes the second data to the second storage device in response to receiving from the host a third write command.

  • Patent number: 5581000
    Abstract: Hydrogen peroxide is produced by oxidizing alkylammonium salts of sulfonic acid-substituted anthrahydroquinones. As said salts are highly soluble in protic polar solvents such as water and lower aliphatic alcohols, the concentration of hydrogen peroxide in the reaction product thereby obtained may be advantageously high. The anthraquinone salt co-product generated by such oxidation may be readily converted in high yield back to the starting anthrahydroquinone salt by hydrogenation.
