Patent CA-2240097-A1 (CA)
Title: Process for the preparation of recombinant proteins in e.coli by high cell density fermentation
Inventor: KNUEPFER UWE
IPC: C12N15/09
Filed: 1996-11-28
Abstract: The invention relates to a fed-batch fermentation process which uses special E. coli host/vector systems for the purpose of efficiently forming recombinant proteins, in particular recombinant antibody molecules, preferably antibody fragments such as miniantibodies. Under the given conditions, the E. coli cells are able to grow at a maximum specific growth rate up to very high cell densities. After the recombinant product formation has been switched on, it is only the formed product which restricts growth; there is no growth restriction due to substrates or metabolic by-products. High space-time yields of recombinant proteins can be achieved in this manner.

Title: Apparatus for coating zinc on steel sheet, and method therefor
Inventor: CHO NOI HA
IPC: C23C24/00
Filed: 1997-10-23
Abstract: An apparatus and a method for coating zinc on steel sheets for use on automobiles and electronic apparatuses are disclosed. A fluidized bed forming chamber is provided to fluidize zinc powders in carrying out a zinc coating on a heated steel sheet, so that not only a uniformly coated layer but also a thick coated layer can be obtained. The apparatus for continuously coating zinc on a steel sheet according to the present invention includes a zinc coating chamber (220) for forming a fluidized bed of zinc powders, for passing a heated steel sheet (201) through the fluidized bed of the zinc powders, and for making the zinc powders melt-adhere on the steel sheet during its passing through the fluidized bed. A fluidized bed forming chamber forms a fluidized bed of the zinc powders by making the zinc powders suspended by spouting a gas. A cyclone (250) separates the zinc powders from the gas after recovery of them from the zinc coating chamber (220), to discharge the gas, and to return the separated zinc powders to the fluidized bed forming chamber (240). A  deflector shifts (211) the advancing direction of the steel sheet after its admittance into the zinc coating chamber (120). A tension roll (232) shifts the advancing direction of a zinc coated steel sheet. Further, the zinc coating chamber includes one or more electrodes for electrostatically charging the zinc powders.

Title: Load reduction of a visitor location register
Inventor: LAHTINEN LAURI
IPC: H04W68/00
Filed: 1996-12-20
Abstract: A problem arises when the data of the visitor location register (VLR) are lost for some reason. In this case, only the visitor location register (VLRn) in whose area the mobile station (MS) is located is known. The mobile station (MS) must then be paged in all location areas (LAn) of the visitor location register (VLR). Such paging of mobile stations causes a significant overload.  The overload is reduced, according to the invention, by dividing the area covered by a physical visitor location area (VLR) into areas of a plurality of logical visitor location registers (LVLRn). In connection with location updatings, not only the physical visitor location register (VLR) is stored but also information on the logical visitor location register (LVLRn) in whose area the mobile station (MS) is located; in a problematic situation where the switching centre (MSC) is not aware of the location area of the mobile station (MS), the mobile station (MS) is paged, at least at first, only in the area of the logical visitor location register (LVLRn).

Title: Video game apparatus and memory medium therefor
Inventor: KOIZUMI YOSHIAKI
IPC: A63F13/5372
Filed: 1998-10-27
Abstract: A video game apparatus includes an RCP. The RCP performs a conversion process on image data to display a player object or non-player object according to image data transferred from an external ROM to a RAM, and supplies the image signal through the display. The RCP detects whether or not there exists a non-player object at around the player object on the display in response to an operation of a Z button. If a non-player object is detected, the RCP selects the non-player object as an attention non- player object. At this time, the hypothetical camera is changed in position and photographing direction such that photographing can be made for the player object directly facing the non-player object.

Title: Portable modular support system
Inventor: FORBES RANDOLPH L
IPC: F24H9/06
Filed: 1998-11-18
Abstract: A modular, dis-assemblable light-weight, portable tubular bridge structure is used for supporting an elongated infra-red (I.R.) heater.  The modular structure enables its use with I.R. system of different length and varying configurations.  The bridge structure has A-frame style support stands with adjustable legs of square section; and carries a square section tubular bridge member or members from which the I.R. heater is suspended.  The A-frame legs impart a degree of flexibility such that a moderate degree of flexing may take place, to accomodate factors such as uneveness of the standing, rough usage and environmental changes.  The system components are not rigidly joined, for mutual accomodation, to minimize stress generation.  One A-frame embodiment has a Tee-bar extending axially, to which the bridge tube is coupled and pinned, by a "sloppy" fit, to ease assembly and stresses.  Some stand embodiments use one or more apex gusset plates, with one or more oversized ports, enabling mis-alignment of adjoining sections of the bridge.  Muff-sleeve couplings can be used to couple pairs of bridge rods together, and for connection to the gusset plates.  Use of a cranked muff-coupling can accomodate charges in direction of the bridge.

Abstract: An occluder (10) insertable into a body passage for limiting the migration of fragments resulting from the disintegration of stones, calculus or the like includes an elongated mandrel (12); a coil (18) closely positioned over part of the mandrel (12), having proximal and distal ends (20 and 22) defining a proximal segment (24) and a distal segment (26) of the mandrel (12) not covered by the coil (18); and a braid (28) positioned over and encircling all of the distal segment (26) of the mandrel (12) and preferably at least part of the wire coil (18). The distal end (16) of the elongated mandrel (12) is fixed with respect to the distal end (34) of the braid (28), while the proximal end (32) of the braid (28) is fixed with respect to the coil (18). The coil (18) and the elongated mandrel (12) are longitudinally moveable with respect to one another between relatively adjacent and relatively spaced-apart positions, such that movement to their relatively adjacent position expands the braid (28) radially so as to occlude the body passage and form a filter (36) which blocks the migration of fragments in the body passage while allowing the flow of fluid in the body passage. The coil (18) is preferably wound from flat wire, while the braid (28) is preferably formed from a woven plurality of strands (30). The occluder (10) can also include a handle (44) connected to the proximal end (14) of the mandrel (12) and to the proximal end (20) of the coil (18), for moving the mandrel (12) and coil (18) between their two relative positions.

Abstract: A coin dispenser is provided for dispensing coins from a stack of coins contained therein. The dispenser includes an elongate casing having an opening at a dispensing end and an inner chamber extending longitudinally through the casing from the opening. The chamber is suitably sized to receive a stack of coins therein.  The dispensing end of the casing is inclined such that the opening therein is generally elliptical in shape while being suitably sized to dispense the coins therethrough. A retaining member spans only partway across the opening for inhibiting the passage of coins through the opening while permitting access to the coins to manually urge the coins sequentially through the opening.

Filed: 1998-12-10
Abstract: A method of cross-compiling computer programs includes the step of extracting constants and field references (62) from an inheriting computer program (44B) written in a first computer language. The extracted constant and field references refer to a generating computer program (60) written in a second computer language. A new generating program (66) in the second computer language is then created using the constants and field references. The new program is then compiled for a target computer (68) to ascertain compiled constant values (70). The compiled constant values are then substituted into the inheriting computer program to produce a final inheriting computer program (47).
