Title: Method of dip moveout analysis on a massively parallel computer
Inventor: WILLEN DENNIS E
IPC: G06F15/80
Filed: 1996-10-02
Abstract: The invention relates to a method of processing seismic data (102, 104) on parallel processors (106, 108, 110), preferably on a massively parallel processor (MPP) (100). The input to the process is seismic data from one or more of a number of seismic lines (2). The end product of the invention is a DMO corrected, zero-offset seismic image of the subsurface. By repeating the method on different input offsets, the variation in reflection strength of a reflector as a function of the angle of incidence can be examined. The method includes a two stage parallelization. First, a parallelization over the incoming traces generates a suite of DMO-corrected partial images for each point on each incoming trace. Secondly, a parallelization over output locations accumulates and combines the partial images, and produces output traces.

Title: Apparatus for drying forage
Inventor: DOEL REGINALD GARTH
IPC: A01F17/00
Filed: 1998-01-07
Abstract: Hay is dried in a mobile vehicle operating directly in the fields. The apparatus gathers hay, and pre-compresses the hay into discrete flakes. A conveyor receives the pre-compressed flakes, and conveys the flakes, in spaced-apart configuration, along a drying tunnel. A propane burner on the vehicle provides drying air, which is blown into the tunnel at entry-ports, and escapes through exhaust-ports. The many ports arestationed alternatingly along the length of the tunnel. The tunnel side-walls are flexible enough that they can be biassed inwards into contact with the passing flakes. This arrangement in the tunnel dries the flakes of hay evenly, right through, while the flakes remain coherant. Upon emerging from the tunnel, the flakes of hay are dry enough for immediate baling, ready for transport and sale.

Inventor: KOHNO YASUYUKI
IPC: B30B1/18
Filed: 1998-01-22
Abstract: A slide driving device employs a variable-displacement pump/motor for driving a rotating element of the slide driving device. The displacement volume of the variable-displacement pump/motor, whose output drives the slide, is varied in response to deviation of measured driver parameters from commanded driver parameters. An energy storage device temporarily absorbs excess energy during a portion of a molding cycle, and returns the energy to the system for reuse. In one embodiment, the energy storage device is an accumulator. In a second embodiment, the energy storage device is a flywheel. The combination of variable displacement volume and energy storage maintains the fluid pressure substantially constant during a cycle of the slide driving device.

Title: Process for preparing supported olefin polymerization catalyst
Inventor: JEREMIC DUSAN
IPC: C08F4/64
Filed: 1998-02-06
Abstract: A catalyst which is useful in slurry or gas phase olefin polymerizations and which is prepared by depositing a combination of an organometallic complex of a group 4 metal and a so-called ionic activator on a metal oxide support. The organometallic complex is characterized by being unbridged and by having a cyclopentadienyl ligand, a phosphinimine ligand and an activatable ligand. The "ionic activator" (for example, triphenylcarbenium tetrakis (pentafluorophenyl) boron) is co-deposited with the organometallic complex. The metal oxide support is pre-treated with, for example, an aluminum alkyl in an amount which is at least equivalent to the molar concentration of surface hydroxyls on the support.      The catalyst prepared by this process is highly active for ethylene polymerization.

Title: Method and apparatus for wrapping a roll
Inventor: EKBLOM KARL
IPC: B65B25/14
Filed: 1997-05-28
Abstract: A method and apparatus for wrapping cardboard and paper rolls for protection during shipping and handling. The rolls are wrapped in a strip of wrapping material, that has a width which does not exceed the length of the roll. The roll is transferred to the wrapping station on a transporter and is stopped using a mechanical positive stop so that an edge of the cylindrical part of the roll is aligned with a first edge of the wrapper roll mounted in the wrapping station. When the roll is stopped, a first layer of the wrapper is wound on the roll. Then, if the length of the roll is greater than the width of the wrapper, the relative position of the roll and the wrapper is changed so that the second edge of the cylindrical part of the roll is aligned with the second edge of the wrapper roll, and a second layer of wrap is wound on the roll.

Patent CA-2241684-A1 (CA)
Inventor: DENNEN MICHAEL WILLIAM
IPC: H01L21/336
Filed: 1997-02-04
Abstract: A Fermi-FET includes a drain field termination region between the source and drain regions, to reduce and preferably prevent injection of carriers from the source region into the channel as.a result of drain bias.      The drain field terminating region prevents excessive drain induced barrier lowering while still allowing low vertical field in the channel. The drain field terminating region is preferably embodied by a buried counterdoped layer between the source and drain regions, extending beneath the substrate surface from the source region to the drain region. The buried counterdoped layer may be formed using a three tub structure which produces three layers between the spaced apart source and drain regions. The drain field terminating region may also be used in a conventional MOSFET. The channel region is preferably formed by epitaxial deposition, so that the channel region need not be counterdoped relative to the drain field terminating region. Higher carrier mobility in the channel may thereby be obtained for a given doping level.
