  • Patent number: 8496472
    Abstract: The present invention is directed to a process for the clean and convenient combustion of high viscosity liquid fuels, such as glycerol, as well as an apparatus useful for carrying such processes. In certain embodiments, the invention provides a process for glycerol combustion comprising providing a combustion apparatus with a glycerol combustion chamber that facilitates reflective heating, pre-heating the glycerol combustion chamber, atomizing the reduced viscosity glycerol, and combining the atomized glycerol with air in the glycerol combustion chamber to thereby completely combust the glycerol. In one embodiment, such as when using a pressure-atomizing nozzle, the inventive method may further comprise treating the glycerol to reduce the glycerol viscosity.

  • Publication number: 20090240956
    Abstract: A system and method for allowing application programs that are external to the relational database to access the sensitive data in the database in a seamless fashion are described. The application programs are allowed to use existing query statements without having to modify such statements for accessing encrypted data in the relational database.

  • Publication number: 20090240937
    Abstract: A novel approach introduces an extra layer of data security by storing files and the keys required to access the files separately. When the files are being accessed, the host of the files sends a request to an access device that stores the keys to access the files. The key will be provided to the host only if at least one of the following conditions is met: the host is within close proximity of the access device, the identity of the person attempting to access the files is authenticated, or the security status of the host is verified.

  • Publication number: 20090225987
    Abstract: A system and method for a mechanism is provided for automatically selecting a new encryption key for re-encrypting data in a target database. New initialization vectors may be specified for re-encrypting each column of data selected for re-encryption. Further, a new initialization vector may be specified for one or more rows of data of a database table in the target database that is selected for re-encryption.

  • Publication number: 20050133654
    Abstract: A paper back tape dispenser that includes a cylindrical outer shell with a center cavity designed to receive a standard roll of paper back tape. The outer shell includes a side opening with a forward extending lip. Formed on the distal edge of the lip is a serrated cutting edge. Aligned and attached to the rear surface of the outer shell is a hollow pipe Formed on the inside and outside surfaces of the short pipe are two longitudinally aligned slots. Located inside the short pipe is a sliding piston. Extending through the piston and the pipe is an axle that partially extends into the cavity to hold a spool that fits inside a roll of tape. A spring is disposed inside the pipe that automatically holds the axle in an upward position on the pipe. During use, the portion of the axle that extends outward acts as a finger bar that is used to lift the axle upward so that new, large roll of tape may be placed over the axle and into the cylindrical cavity.

  • Patent number: 6808611
    Abstract: Embodiments of the invention provide an electro-analytical method for determining the concentration of an organic additive in an acidic or basic metal plating bath using an organic chemical analyzer. The method includes preparing a supporting-electrolyte solution, preparing a testing solution including the supporting-electrolyte solution and a standard solution, measuring an electrochemical response of the supporting-electrolyte solution using the organic chemical analyzer, and implementing an electro-analytical technique to determine the concentration of the organic additive in the plating bath from the electrochemical response measurements. The method is performed for independently analyzing one organic additive component in a plating bath containing multi-component organic additives, regardless of knowledge of the concentration of other organic additives and with minimal interference among organic additives.
