Patent CA-2353792-A1 (CA)
Inventor: LIAO HANS
IPC: C12Q1/6865
Filed: 1999-12-07
Abstract: The present application relates to mutated RNA polymerases from bacteriophages that have increased stability, for example under high temperature conditions. One example of bacteriophage encoded RNA  polymerase is the T7 RNA polymerase. 77 is a bacteriophage capable of infecting E. coli cells. Examples of other E. coli infecting T7-like bacteriophages are T3, .slzero.I, .slzero.II, W31, H, Y, A1, croC21, C22 and C23. An example of a Salmonella typhimurium infecting bacteriophage is SP6. The present invention is concerned with the RNA polymerases of T7-like bacteriophages that have been mutated. Due to these mutations the RNAP's have an increased stability.  Preferred mutated RNA polymerases according to the invention are mutant RNA  polymerases from 77 or SP3 bacteriophages. Due to the high homology between these enzymes, mutations in the T7 gene 1 sequence are likely to have the same effect in the corresponding gene sequence of the T3 bacteriophage. An especially preferred embodiment of the present invention is a T7 RNA polymerase with a serine to proline amino acid change in the protein at position 633 of the amino acid sequence. Since there is 80 % homology between the T7 RNA  polymerase and the T3 RNA polymerase the same effects of the 633 serine.fwdarw.proline mutation in the 17 gene may be expected for a 634 serine.fwdarw.proline amino acid mutation in the T3 RNA polymerase.

Title: Steam cooling apparatus for gas turbine
Inventor: KITA YOSHIYUKI
IPC: F01K23/10
Filed: 2001-11-27
Abstract: An apparatus and method for steam cooling a gas turbine. An intermediate-pressure drum 106 of a recovery boiler supplies outlet steam, as a cooling steam, to a combustor 117 through a steam channel 116. The flow rate of steam guided into the combustor 117 is adjusted through opening or closing of a first flow control valve 120 by a controller 125 such that the pressure of the intermediate-pressure drum 106 becomes a set value set according to a load status of a gas turbine 101. A required amount of steam according to the load status of the gas turbine 101 is fed to the combustor 117. Thus, the flow rate of steam guided into the combustor 117 is controlled by adjustment of the existing first flow control valve 120 for maintaining the pressure of the intermediate- pressure drum 106 in a predetermined state, without the need to provide an expensive valve device in the steam channel 116. 59

Abstract: A device and a method for simulation (1) of firing by means of a weapon (2). The simulator is mounted onto a weapon with a sight (3), with the simulator arranged to emit an electromagnetic simulator beam exiting along a simulator axis (5). Furthermore, the simulator (1) is arranged to emit a visible alignment beam along an alignment axis (7) that has a fixed angular relationship to the aforementioned simulator axis (5). The simulator contains a means of adjustment to collectively control both of the aforementioned axes so that they maintain their fixed relative angular relationship during an alignment. The alignment beam may generate an alignment mark (9) which, when observed in the sight (3) of the weapon, indicates the error in alignment between the simulator axis (5) and the sight (3). This makes it possible for a firer easily to align the sighting axis to the simulator axis with the aid of the means of adjustment.

Title: Lzw data compression/decompression apparatus and method with embedded run-length encoding/decoding
Inventor: COOPER ALBERT B
IPC: H03M7/30
Filed: 2000-06-15
Abstract: In an LZW data compressor, the occurrence of a character run in the input character stream is determined and the run count is added to the existing code in the compressor code counter to generate a compressor code output representative of the run count. The LZW data decompressor subtracts the existing code in the decompressor code counter from the received compressed code to recover the run count. In accordance with a further feature, large length runs are processed by reducing the run count to less than the system maximum code by subtracting a selected predetermined constant from the run count. The reduced run count is outputted by the compressor preceded by a reserved code representative of the selected predetermined constant. In response to the received reserved code and the reduced count that follows, the decompressor adds the selected predetermined constant corresponding to the received reserved code to the received reduced count to recover the original run count.
Patent CA-2374492-A1 (CA)
Title: Connection for floor covering in vehicles, in particular, in rail vehicles
Inventor: MARTENS HOLGER
IPC: B61D17/18
Filed: 2000-06-06
Abstract: The invention aims to compensate for tolerances which occur in the interior construction of rail vehicles, using a floating floor construction and to allow a force-reducing relative displacement between the installation components which are permanently mounted onto the construction shell, such a s seats, back panels, cupboards etc. and the floor, whilst excluding the penetration of moisture between the permanently mounted attachments or installed sections and the floor, which can be displaced in relation to each  other. This is achieved by a corner profile (12), located between the floor plate (5) and the attachments or installed sections (18) that are permanentl y mounted onto the construction shell. Said corner profile runs both longitudinally and transversally in relation to said attachments and section s, forming a bearing surface (11) for the floor covering. One limb (13) of said  corner profile forms the edge of the floor plate (5) which is to receive the  floor covering and the other limb (15) is positioned so that it can be displaced in a longitudinal and transverse direction, in relation to the construction shell. The horizontal tolerance compensation can be absorbed by  a flexible seal (17) which is fixed to the limb (15) and lies against the construction shell.
