Title: Cold dense slurrying process for extracting bitumen from oil sand
Inventor: SPENCE JONATHAN
IPC: C10G1/04
Filed: 1997-10-02
Abstract: Average grade oil sand is mixed with water to produce a low temperature (preferably 20 - 35°C), dense (1.4 -1.65 g/cc) slurry. The slurry is pumped through a pipeline for sufficient time to condition it. Air is injected into the slurry after the last pump. The slurry density is adjusted to about 1.5 g/cc by adding flood water near the end of the pipeline. The slurry is introduced into a primary separation vessel (PSV), excess air is vented from the slurry as it is introduced into the PSV and a hot water underwash is used to heat the froth produced. Slurry loading to the PSV is greater than about 4.78 tonnes of oil sand/hour/square meter to reduce velocity gradient in the fluid in the vessel. Bitumen froth is recovered. When fed low grade oil sand, the process is modified by adding flotation aid chemicals to the slurry in the pipeline and subjecting the PSV tailings and middlings to secondary recovery with agitation and aeration in a secondary separation vessel.

Inventor: ROOS UWE-VOLKER
IPC: B29C49/06
Filed: 1997-12-02
Abstract: The present invention relates to a parison loading station for reheat blow-molding machines.  Such machines pose the problem that the sleeve-like or cartridge-like cold parisons which are produced as a supply unit have to be moved from the feed position ~bottom down" into the attachment position ~bottom up" before being moved through a heating path on the transportation mandrels of a transportation means where they are heated to the right blow-molding temperature.  Such a movement is performed by means of a reversing wheel (7) which rotates the parisons by 180° and transfers them to a loading wheel (15) from which they are pressed onto the transportation mandrels 12.  This is accomplished according to the invention in that the loading stationcomprises a continuously rotating reversal wheel 7 with a horizontal axis 13 and a cyclically rotating loading wheel 15 which removes the parisons from the reversing wheel and has a vertical axis 14 and from which the parisons are put or attached onto the transportation mandrels 12 by means of a press-on system 16, the attaching operation being performed in a standstill phase of the transportation means of the reheat machine at a simultaneous standstill of loading wheel, and the drive of the loading station being connected to the permanently rotating drive shaft of the drive system 17 of the transportation means of the reheat machine.

Filed: 1996-11-05
Abstract: A cell population or subpopulation enrichment procedure (10) for separating undesired populations or subpopulations from a biological sample (12) utilizing relatively heavy, dense particles (14) and gravity sedimentation. The particles have one or more reactants bound thereto which are specific to and will bind with the selected population or subpopulation to be eliminated from the sample. The particles preferably are mixed with the sample by repeatedly causing the particles to settle through a substantial portion of the sample to bind to the selected population. The particles with the bound selected population to be eliminated then are allowed to preferentially settle in the sample and the supernatant including the enriched population or subpopulation is separated from the particles with the population to be eliminated bound thereto. The enriched population supernatant can then be analyzed, utilized as is, have other populations or subpopulations removed or have additional amounts of remaining cells of the previously eliminated populations removed in additional steps.

Title: Method and apparatus for photogrammetric assessment of biological tissue
Inventor: DERKSEN GRANT D
IPC: G01C11/00
Filed: 1996-11-14
Abstract: A remote wound assessment method and apparatus includes forming an oblique image (32) of a wound (34) and a target object such as a plate (36) containing a rectangle (37) and placed near the wound. Using a novel method of determining vanishing points (V1, V2) where photographic images of parallel lines on the target object intersect, coordinate transformations are calculated which map the oblique image (36I) of the rectangle (37I) into a normal image (36N) thereof. Using the same coordinate transformations, an oblique image (34I) of a wound (34) adjacent to the target plate (36) is mapped into a normal view (34N) thereof, allowing precise measurement of wound features.      By forming two separate images (32L, 32R) of a wound (34) and target plate (36) at two different oblique inclinations, three-dimensional features of a wound may be measured.

Title: System and method for electrosurgical cutting and ablation
Inventor: THAPLIYAL HIRA V
IPC: A61B17/00
Filed: 1996-11-19
Abstract: An electrosurgical probe (10) comprises a shaft (13) having an electrode array (58) at its distal end and a connector (19) at its proximal end for coupling the electrode array to a high frequency power supply (28). The shaft includes a return electrode (56) recessed from its distal end and enclosed within an insulating jacket (18). The return electrode defines an inner passage (83) electrically connected to both the return electrode and the electrode array for passage of an electrically conducting liquid (50). By applying high frequency voltage to the electrode array and the return electrode, the electrically conducting liquid generates a current flow path between the return electrode and the electrode array so that target tissue may be cut or ablated. The probe is particularly useful in dry environments, such as the mouth or abdominal cavity, because the electrically conducting liquid provides the necessary return current path between the active and return electrodes.

Patent CA-2252842-A1 (CA)
Inventor: ARAI HIDEAKI
IPC: B60L50/13
Filed: 1998-02-20
Abstract: An alternator for an engine normally operated as a generator is caused to operate as a synchronous motor according to the operating condition of the engine. If power generation by the alternator 1 is no longer necessary because a battery 9 is fully charged, or when the engine enters an acceleration condition, a switching controller 5 switches stator coils 12 for the alternator 1 from an output controller 7 to a rotating magnetic field generator 8. The rotating magnetic field generator 8 causes a stator 1S to generate a rotating magnetic field that rotates with a same rotation speed of a rotor 1R, so that the alternator 1 operates as a synchronous motor to generate such a torque as to assist the torque or rotation of the engine. If the engine speed is likely to exceed a maximum limit, or when the engine enters a deceleration condition, the stator is caused to generate a rotating magnetic field with a phase angle relative to a direct-current magnetic field of the rotor so that the alternator generates such a torque as to suppress the engine speed.
