Title: Specifying indexes for relational databases
Inventor: LENZIE ROBERT STEPHEN
IPC: G06F17/30
Filed: 1996-12-16
Abstract: An index set for a database is specified by analysing a sample (718) of SQL statements applied to the database (701) . Indexes (707) are identified. that could assist in the execution of the analysed statements and levels of improved operation are evaluated for each of said indexes.      The evaluated levels are then processed (708) to specify an index set for inclusion on the database. The database may not include sufficient storage (702) for all of the specified indexes to be included, therefore the available storage space is allocated and indexes are selected on a prioritized basis.

Title: Parallel file system and method using tokens and metadata nodes
Inventor: SCHMUCK FRANK B
IPC: G6 F15/167
Filed: 1998-07-09
Abstract: A computer system having a shared disk file system running on multiple computers each having their own instance of an operating system and being coupled for parallel data sharing access to files residing on network attached shared disks. Methods are provided for use as a parallel file system in a shared disk environment by use of a scalable directory service for the system with a stable cursor, a segmented allocation map. Dynamic prefetch and cached balance pools for multiple accesses improve the system. Extended file attributes and attribute value sharing are used for implementation of access control lists in a parallel file system. A metadata node manages file metadata for parallel read and write actions. For our system, tokens are used for metadata node selection and identification. Enhanced token modes for controlling file size, as well as smart caching of byte range tokens using file access patterns and a byte range lock algorithm using a byte range token interface are provided. Locking techniques reduce the overhead of a token manager which is also used in the file system recovery if a computer participating in the management of shared disks becomes unavailable or failed. Synchronous and asynchronous takeover of a metadata node occurs for correction of metadata which was under modification. Locks are not constantly required to allocate new blocks on behalf of a user. Recoverable local shares for quota management are provided. A quota server and a quota client are provided for each file system, and a quotacheck utility allows parallel environments with minimal interference to other applications which require the use of quotas.

Inventor: OBERLE TIMOTHY T
IPC: B65D75/00
Filed: 1998-09-22
Abstract: An L-seal patch bag has an open top, a bottom seal, a seal along a first side edge, and a patch covering a seamless second side edge. The bag is preferably made by adhering, at intervals and across a continuous flat film, a plurality of discrete film patches. Each of the patches covers a centerline naming the length of the elongate flat film. The resulting laminated article is then folded along its length, preferably at the centerline, making a first seal by sealing the elongate flat film to itself by sealing along a first (open, non-seamless) side edge of the elongate flat film. A second seal is then made by sealing across an entirety of the folded, laminated article, which is thereafter cut across below the second seal, whereby an L-seal patch bag is produced. Analogous processes can be used to produce a side-seal patch bag or a backseamed patch bag. Still another process of making a side-seal patch bag involves folding the elongate flat film transversely before sealing along the side edges and cutting the resulting side-seal bag from the remainder of the elongate flat film.

Patent CA-2256744-A1 (CA)
Inventor: KOUTITONSKY SERGE
IPC: D21H23/28
Filed: 1997-06-05
Abstract: A method for making a surface coated or impregnated paper or paperboard by applying an aqueous additive dispersion to the wet web between the press and drying sections of a conventional paper or paperboard making machine. The aqueous additive dispersion is premetered onto a transfer roll and is applied to the wet web at a pressure nip between the transfer roll and a back-up roll.  High solids content dispersions can be applied at high web speeds without tearing the web. The use of a high solids content aqueous dispersion having a solids content substantially equal to the solids content of the wet web at the point of application permits the method to be performed without increasing the drying load and therefore at an unreduced speed. The method contemplates the use of a hydrophilic transfer roll running in a direction opposite to the web, permitting a saturant to be impregnated into the web, and has particular application to the production of containerboard treated with a lignosulfonate saturant to improve strength and surface character.

Title: Improved transcutaneous electromagnetic energy transfer
Inventor: CHEN JAMES C
IPC: H02J17/00
Filed: 1997-06-26
Abstract: A method and apparatus for enhancing transcutaneous energy transfer to provide power to a medical device that is disposed within the body of a patient. A  magnetic field is created by an external transmitting coil (200), which induces an electrical current in a receiving coil (300) that has been placed under the patient's skin (100). The flux path magnetic permeability between the receiving and transmitting coils is enhanced by the implantation of particles (120) into dermis (104) within the skin at that site. The particles, which comprise soft iron or other material having a characteristic high magnetic permeability, are preferably implanted using either a hypodermic needle (150) or a medical air injection device (160). A biocompatible material such as TeflonTM is applied as a coating (123) to the particles. To implant the particles, they are preferably first suspended in a liquid, forming a mixture that is readily delivered to the desired location. The particles are dispersed in a deposit below the epidermis, so that the deposit is between pole faces of the transmitting and the receiving coils. The efficiency of transcutaneous power transfer increases because the magnetic flux density coupling the transmitting and receiving coils is improved by the particles.
