Title: Efficient storage of objects in a file system
Inventor: ZBIKOWSKI MARK
IPC: G11B27/32
Filed: 1994-06-10
Abstract: A file system provides a hierarchical approach to storage of file data. Logically contiguous bytes of file data are stored in stream data structures, and streams which hold related file data are stored in a variable sized onode data structures on disk. The variable-sized onode data structures are stored in fixed sized buckets, and the buckets are organized into a variable sized array. Thus, the file system provides a combination of variable-sized storage with fixed-sized storage to provide a very efficient approach to storing file data. In addition, indexes may be provided within the structures to allow quick access to onodes and streams.

Title: Carton for bulk pack cut single paper
Inventor: GOTTFRIED THOMAS M
IPC: B65D5/32
Filed: 1994-06-30
Abstract: ABSTRACT OF THE DISCLOSURE       A cardboard carton is constructed that is particularly useful for holding a stack of paper so that individual cut sheets from the stack may be readily removed.  The carton bottom has an open top and substantially open ends and closed sides, while the carton top has a Z-fold top panel, and one or more tear strips between adhesive connecting the carton top to the carton bottom and the main part of the carton top.  The carton bottom, with its open top facing downwardly, is either moved over a stack of paper, or formed over the stack of paper.  Then it is rotated 180° about a horizontal axis (as by pivoting a U-shaped continuous conveyor about a horizontal axis), and conveyed to a station where it is moved with respect to a carton top so that the open bottom of the carton top goes over the carton bottom, and then is glued in place.  Two opposite flaps on the carton lid may be glued to the bottom surface of the carton bottom panel to provide a lifting space beneath the carton.  The side and end flaps of the carton bottom may be connected to the bottom panel by perforations to allow ready detachment.

Title: Method and Apparatus for the Removal of Hydrogen Sulfide from a Process Gas Stream
Inventor: HUESTIS ALLAN C
IPC: F27B1/10
Filed: 1994-08-16
Abstract: An improved method and apparatus for forming metallized iron by direct reduction of particulate iron oxide is disclosed.   Spent reducing gas  is recycled from the reduction furnace through a cooler-scrubber  and  a  catalyst-containing stoichiometric  gas reformer.  Upon removing the process gas from the cooler-scrubber, it is contacted with a chlorine dioxide spray, then compressed and cooled, the sulfur compound removed, and the process gas recycled either into the furnace cooling zone, or directly into the reformer, or divided and directed into both uses.  Thus, most of the sulfur containing components of the spent reducing gas are removed, thereby reducing the sulfur contamination of the gas reformer catalyst. Reducing sulfur contamination of the gas reformer catalyst improves the overall efficiency of the direct reduction process.  Either high sulfur ores, or high sulfur process gas, or both can be utilized in the invented process.

Title: H-bridge type power amplifier and its blocking means
Inventor: GERFAULT BERTRAND
IPC: H03F3/217
Filed: 1994-11-02
Abstract: ABSTRACT OF THE DISCLOSURE          H-Bridge type power amplifier and its blocking means The invention concerns H-bridge type power amplifiers and their blocking means. The memory effect of the capacitive impedance of control inputs of each of the two blocking transistors in the H-bridge is used to block and unblock the amplifier synchronously with the amplifier input signal: a first switch and a semi-conductor element are placed in parallel with each other, in series with each of these control inputs, such that the blocking of the blockingtransistor necessitates the opening of the first switch under the control of theblocking signal, and is dependent on the sign of the charge carried by said capacitive impedance; a second switch controlled by the half periods of the input signal only enables the first switch to close and therefore unblocking of the considered blocking transistor for half periods that are not amplified by this blocking transistor.

Abstract: 2135284 9323131 PCTABS00028 In a solvent recovery plant comprising a recovery tower (4) from which solvent product is recovered overhead, an isothermal separator, preferably a cyclone (13), is used to separate liquid phase contaminant (i.e. oil in a lubricating oil extraction process) in overhead product and to feed the separated liquid to the recovery tower as reflux. In addition, a portion of the feed to the tower can be branched off (in branch line 10) and mixed with the overhead product (in overhead line 11), to bring its temperature down to close to the dew point of the solvent vapour. In this way, flooding of the uppermost tower trays and distillation of oil overhead can be overcome.

Title: Application of microspheres to in situ separation of water and oil
Inventor: GLEADALL GEORGE B
IPC: E21B33/13
Filed: 1995-05-09
Abstract: To combat the problem of water infiltration into an oil reservoir, a technique of injecting a fluid into the reservoir to cause separation between the oil and water is now available.  This fluid will have a specific gravity matched to the conditions of the reservoir so as to float on the water and sink in the oil.  In this way, it can be assured that the fluid will form a separation barrier between the water and oil.   This invention contains two procedures, one to create a hard barrier and the other to create a soft barrier.   Once the barrier is in place, it is possible to resume profitable production of the well yet again.
