Patent CA-2125405-A1 (CA)
Title: Reaction-based selection for expression of and concentration of catalytic moieties
Inventor: BLACKBURN GARY F
IPC: C12Q1/70
Filed: 1993-02-24
Abstract: Disclosed and claimed are methods for selecting a recombinant virus, phage or cell expressing a catalytic antibody or catalytic portion thereof, or for selecting catalytic activity by a moiety.  The method employs reaction-based selection for catalytic activity. The method can also be used to concentrate (increase the proportion of catalytic to non-catalytic moieties) a sample containing a catalytic moiety or viruses, phages or cells expressing a catalytic moiety. The selection or concentration can be by employing a mechanism-based inhibitor, catalysis-accelerated movement, surface binding, changes in enthalpic component of binding as a function of temperature, or changes in binding by competition, or combinations thereof. The invention also comprehends a method for producing a recombinant virus or a cell-line expressing a catalytic moiety such as a catalytic antibody or catalytic portion thereof;  and, this method can include infecting a suitable host with viruses which are screened for the expression. In addition, recombinant viruses and cell-lines so expressing a catalytic moiety such as a catalytic antibody or catalytic portion thereof are also disclosed and claimed.

Title: Molded structure comprising a thermoplastic, process for its production and its use
Inventor: VONKEN HUB A G
IPC: B29C48/14
Filed: 1994-08-02
Abstract: A molded structure 1 produced by extrusion, such as an expanded plastic foam, a sheet, a profile or the like, contains at least 10% by volume of open cells 2, 4 which have a polyhedron-like shape and are adjacent to one another. A higher temperature during the extrusion in comparison with the extrusion of thermoplastic molded structures having a closed-cell structure results in deformation-free opening of the cells. Webs 3 of cell walls 5, 6 remain intact in shape whether they have orifices 7 or no passages, so that the mechanical strength of the cell skeleton or of the space matrix is retained.

Patent CA-2133902-A1 (CA)
Title: Coded seal
Inventor: YUEN KI S
IPC: G06K19/06
Filed: 1994-10-20
Abstract: The present invention is directed to a coded seal which allows a device to determine whether unauthorized access to a terminal or other electronic or security device has been made.  The code includes a series of continuous and discontinuous members which are used to form a code. Breaking of the seal causes the members to be discontinuous and makes it difficult to determine what the code was.  In this way, it is difficult to replace the seal, as this would only be successful if the replacement seal had the same code.

Title: Dual fuel gas turbine combustor
Inventor: MARSHALL DIANE M
IPC: F23R3/06
Filed: 1994-12-02
Abstract: A combustor for a gas turbine having primary and secondary combustion zones.  The combustor has a centrally disposed dual fuel nozzle that can supply a fuel rich mixture of either liquid and gaseous fuel to the primary combustion zone.  The combustor also has primary gas fuel spray bars for supplying a lean mixture of gaseous fuel to the primary combustion zone via a first annular pre-mixing passage and secondary gas fuel spray bars for supplying a lean mixture of gaseous fuel to the secondary combustion zone via a second annular pre-mixing passage.  In addition, the combustor also has a plurality of liquid fuel spray nozzles for introducing a lean mixture of liquid fuel into the secondary combustion zone via the second annular pre-mixing passage.  The liquid fuel spray nozzles are disposed in fan shaped channels that are arranged in a circumferential array and that are connected to the second annular pre-mixing passage.   The fan shaped channels cause expansion of the spray of fuel from the liquid spray nozzles and serve to ensure good atomization of the liquid fuel prior to its introduction into the second annular pre-mixing passage.

Title: Surface-normal semiconductor optical cavity devices
Inventor: GOOSSEN KEITH WAYNE
IPC: G02F1/21
Filed: 1995-04-19
Abstract: A multi-layer mirror structure included in a surface-normal semiconductor optical cavity is fabricated in a deposition reactor dedicated to that purpose alone. Additional layers of the device are subsequently deposited on top of the mirror structure in a second reactor. In practice, the dedicated reactor produces layers whose thickness variations over their entire extents are considerably less than the thickness variations of layers made in the second reactor. This coupled with the fact that the actual achieved thickness of the mirror structure can be conveniently measured before commencing deposition of a prescribed thickness of the additional layers makes it possible to fabricate a specified-thickness optical cavity within tight tolerances in a high-yield manner.

Abstract: In multilevel construction it is well known that the Flying-form Tables are used for supporting cast in place concrete slabs. The Flying-form Tables are constructed of trusses and a deck on top. Currently the deck on top is constructed of aluminum or wood joists and plywood deck. The joists provide the basic surface on which the plywood deck is mounted. The plywood deck could be used only for a very limited number of times.  In this invention the deck on top is constructed of reusable metal deck and metal flat plate on top which is spot welded or screwed to the deck. This assures much better utilization of the flying system, reducing labor and material costs, permits faster cycling and reduces overall costs.
