Title: Tip for a liquefaction handpiece
Inventor: COHEN DONALD M
IPC: A61B18/04
Filed: 1999-04-19
Abstract: A tip for a liquefraction surgical handpiece. The tip uses at least two lumens. One lumen is used for aspiration and another, smaller lumen is used to inject heated surgical fluid for liquefying a cataractous lens. The distal portion of the injection lumen terminates just inside of the aspiration lumen so that heated fluid escaping the injection lumen is reflected off of the internal wall of the aspiration lumen prior to entering the eye. Such an arrangement prevents the injected fluid from directly entering the eye. The handpiece may also contain other lumen, for example, for injecting relatively cool surgical fluid.

Title: Multiple drain method for recovering oil from tar sand
Inventor: SCHMIDT BRIAN H
IPC: E21B43/24
Filed: 1999-05-21
Abstract: A thermal method is described for recovering normally immobile hydrocarbon oil from a subsurface tar sand deposit. The procedure comprises: (a) establishing at least one substantially vertical production bore hole extending from the surface of the earth to at least the bottom of said subsurface formation; (b) providing a plurality of bore holes extending downwardly from the surface of the earth through the tar sand formation to substantially the bottom thereof and then substantially horizontally at or near the bottom of the tar sand formation and converging radially inward to each bore hole, each radial bore hole containing a perforated or slotted tube; (c) continuously injecting steam downwardly through the perforated or slotted tubes whereby the steam discharges through the perforations or slots and into the tar sand formation to reduce the viscosity of the normally immobile oil, with a substantial proportion of the steam being injected into the formation via the portion of each tube extending downwardly through the tar sand formation whereby the steam reduces the viscosity of the normally immobile oil over an area extending substantially between the perforated tube and the top of the tar sand formation with this viscosity reducing area expanding radially and moving axially inwardly toward the vertical production bore hole thereby creating an expanding generally conical-shaped production chamber; and (d) draining the less viscous oil and steam condensate thus obtained downwardly by gravity to the bottom of the production chamber and then through the horizontal tubes into the bottom of the vertical production bore hole for collection.

Title: Method and apparatus for providing failure detection and recovery with predetermined replication style for distributed applications in a network
Inventor: SHIH CHIA-YEN
IPC: G06F15/177
Filed: 1999-06-03
Abstract: An application module (A) running on a host computer in a computer network is failure-protected with one or more backup copies that are operative on other host computers in the network. In order to effect fault protection, the application module registers itself with a ReplicaManager daemon process (112) by sending a registration message, which message, in addition to identifying the registering application module and the host computer on which it is running, includes the particular replication strategy (cold backup, warm backup, or hot backup) and the degree of replication associated with that application module. The backup copies are then maintained in a fail-over state according to the registered replication strategy. A WatchDog daemon (113), running on the same host computer as the registered application periodically monitors the registered application to detect failures. When a failure, such as a crash or hangup of the application module, is detected, the failure is reported to the ReplicaManager, which effects the requested fail-over actions. An additional backup copy is then made operative in accordance with the registered replication style and the registered degree of replication. A     SuperWatchDog daemon process (115-1), running on the same host computer as the ReplicaManager, monitors each host computer in the computer network. When a host failure is detected, each application module running on that host computer is individually failure-protected in accordance with its registered replication style and degree of replication.

Abstract: A rotary disc refiner includes a pair of spaced apart refiner discs for refining or grinding a material that typically is fibrous material such as wood pulp or the like. Pressurized vapor, typically steam, produced as a result of the refining or grinding is exhausted through a channel in the refiner disc which extends through the bo dy of the disc. Preferably, the channel is located in a refiner disc that rotates. The  channel includes a vapor inlet opening located preferably in the high pressure midsection of the refiner disc, a vapor outlet opening which discharges the steam to the relatively low pressure outer section of the disc, and a passageway behind the refining or grinding surface of the refiner disc connecting the inlet to the outlet.
Patent CA-2278396-A1 (CA)
Inventor: SHIMIZU JOHSUKE
IPC: C07K14/78
Filed: 1999-07-22
Abstract: A collagen is extracted and produced from a raw fish skin through the steps: a salt admixing step for admixing a salt (e.g. NaCl, KCl or the like) with raw fish skin so as to allow non-collagen substances or portions (including fats and tissue portions other than collagen portions) to be removed from the fish skin, while simultaneously degreasing and deodorizing the skin under the salt effect; a salt removal step for causing the admixed salt and non-collagen substances or portions to remove from the skin, achieving the fats removal and deodorization; a collagen extraction step for extracting a collagen (gelatinous) from the this-treated skin; and a filtration step for filtering and refining the extracted collagen so as to obtain a refined collagen. The refined collagen may be dried and solidified. Thus, since inexpensive salt is used for effective removal of non-collagen substances or portions to obtain a collagen portion, the method itself is simplified and economical. Further, the fish collagen obtained thereby, be it fluid or dried, is of a highly refined property, i.e., colorless, odorless and degreased, which is suitable for food product elements and various industrial uses.
Patent CA-2279613-A1 (CA)
Inventor: TOYAMA KEISUKE
IPC: A61B5/04
Filed: 1999-08-04
Abstract: Disclosed herein is a technique for accurately determining states of bioelectric currents occurring in particular positions in a site of interest of a patient. Transfer functions between the particular positions and each magnetic sensor are derived from a positional relationship between the site of interest and each magnetic sensor. Weight coefficients are computed from an inverse matrix obtained by adding a pre-determined value to a matrix of the transfer functions, and virtual biomagnetism information obtained virtually by bioelectric currents set to the particular positions.      Enhanced biomagnetism information with only the biomagnetism from the particular positions enhanced is acquired by superposing the weight coefficients on measured biomagnetism information. Based on this enhanced biomagnetism information, states of bioelectric currents occurring in the particular positions are determined accurately.
