Patent CA-2191512-C (CA)
Inventor: ZHOU ZHIHONG
IPC: E21B33/138
Filed: 1996-11-28
Granted: 2003-08-05
Abstract: A method is provided for blocking high permeability channels in subterranean geological formations, using swelling clay. A slurry is prepared by mixing swelling clay, such as bentonite, into an aqueous solution containing the salt of certain cations, which inhibit clay swelling. The cations K~, Ca2~ and Mg2~, among others, are inhibitive of clay swelling. The clay slurry is introduced into a geological formation, where it preferentialy enters channels of high permeability. There the slurry is contacted by NaCl brine solution present in natural or injected drive fluids, and the inhibitive cations bound to the clay particles are replaced by Na~ ions, which attract water molecules and promote clay swelling. The Na~ - clay swells to up to 10 times its original volume, causing the shiny to acquire a gel- like consistency. The clay gel so formed is capable of blocking the flow of water, and can resist pressure of up to 500 kPa per meter.

Title: Process for peeling off temporarily protecting coating film
Inventor: TOJO HIDEAKI
IPC: B08B3/02
Filed: 1997-01-09
Granted: 1999-09-28
Abstract: In peeling off, from a coating surface, temporarily protecting coating films formed by applying a protecting coating material onto the coating surface after completion of the coating, high-pressure water is jetted toward between the coating surface and end edges of the temporarily protecting coating films to peel off the end edges from the coating surface.      Then, the high-pressure water is jetted sequentially to between the coating surface and peeled-off portions of the temporarily protecting coating films from the coating surface to peel off the entire temporarily protecting coating films from the coating surface. Thus, the temporarily protecting coating films can be easily peeled off without being influenced by the temperature of an environment, leading to a shortened peeling-off time.

Granted: 2001-02-13
Abstract: A non-broadcast multi-access network system comprises a plurality of network servers at least specific one of which servers employs Next Hop Resolution Protocol for converting a network layer address into a corresponding data link layer address.  The specific network server comprises a routing table access section (102) for accessing a routing table to refer to the routing table representative of a routing of a network layer.  An NHRP server table (103) stores server address information of at least particular one of the network servers and network layer address information of the network layer managed by the particular network server as an address set.  An NHRP server processing section (101) is supplied with a Next Hop Resolution Protocol packet having a destination network layer address for accessing the NHRP server table to judge whether or not the destination network layer address exists in the address set.  The NHRP server processing section transmits the Next Hop Resolution Protocol packet to the particular network server when the destination network layer address exists in the address set.  The NHRP server processing section controls the routing table access section to make the routing table access section refer to the routing table when the destination network layer address does not exist in the address set.

Abstract: On a découvert qu'en utilisant un vecteur viral d'ADN recombiné, de préférence un vecteur viral de poxvirus présentant au moins un site d'insertion contenant un segment d'ADN codant l'antigène auto-associé à un carcinome ou son épitope faisant apparaître des lymphocytes T cytotoxiques, lié fonctionnellement à un promoteur capable d'une expression dans l'hôte, il est possible de produire des lymphocytes T humains cytotoxiques spécifiques des antigènes auto-associés à un carcinome. Le procédé consiste de préférence à introduire une dose suffisante du vecteur de poxvirus recombiné dans un hôte pour stimuler la production de lymphocytes T cytotoxiques, puis à mettre en contact l'hôte avec un antigène supplémentaire à intervalles périodiques. Ledit antigène supplémentaire peut être ajouté à l'aide d'un second vecteur de poxvirus tiré d'un autre genre de pox. Dans un autre mode de réalisation, on ajoute l'antigène supplémentaire en mettant en contact l'hôte avec l'antigène. Ledit antigène peut être formulé avec un adjuvant ou dans une formulation liposomique. On peut isoler les lymphocytes T. Le nombre de lymphocytes T peut être augmenté par mise en contact des lymphocytes T cytotoxiques isolés alternativement avec l'antigène auto-associé à un carcinome ou avec son épitope et l'IL-2. Les lymphocytes T isolés peuvent être utilisés dans un procédé de traitement d'un hôte présentant une tumeur exprimant un antigène auto-associé à un carcinome, consistant à introduire des lymphocytes T cytotoxiques spécifiques de l'antigène dans l'hôte, puis à introduire dans l'hôte, au moins après un intervalle périodique, un épitope faisant apparaître des lymphocytes T de l'antigène auto-associé à un carcinome.

Granted: 2005-05-24
Abstract: A separating system for separating material transported by air utilizing apparatus having a tangential inlet for a stream of air and entrained material, a bottom material exit, a boundary wall air exit and a central interior air exit. Each air exit includes a perforated wall or screen through which air is removed or separated from the entrained material.      Enhanced separating action is achieved through coupling two such separators in a loop arrangement such that the material discharge from a first separator is conveyed via a relay stream of air to serve as the input to a second separator, while the entire air exhaust from the second separator is returned as one of a plurality of inlet streams to the first separator. A further advantage is realized by partitioning the air exhaust of the first separator into a plurality of parallel passageways which can be individually closed. Associated with each passageway is a nozzle through which a compressed air blast is introduced into the passageway that is effective to reverse the air flow therein and clear the associated perforated wall or screen of accumulated scrap material without halting the material separating operation.
