Title: Water-in-oil microemulsions and their preparation
Inventor: ZARD PAULINE WILLIAM
IPC: C09K23/16
Filed: 1997-05-02
Abstract: A surfactant composition is described. This composition is used for the emulsification of oil and water to form microemulsions.

Patent CA-2291805-A1 (CA)
Inventor: FAIR DELOME D
IPC: B01D47/06
Filed: 1998-06-05
Abstract: A system for quenching and scrubbing hot partial oxidation gas and washing and cooling hot partial oxidation gas is disclosed. During the quenching and scrubbing phase, removal of particulate contaminants is facilitated by using a high pressure settler assembly in combination with a scrubbing tower (10). Preferably, the high pressure settler consists of a sump (18) internal to the scrubbing tower or a sump and quiet zone combination that is internal to the scrubbing tower.  Use of the high pressure settler allows for increased settling rates and increased scrubbing efficiency. During the cooling and washing, a knockout drum (45) having an integral washing system is advantageously employed. Use of the knockout drum during the condensing and washing phase of gasification process facilitates removal of ammonia and water vapor from a partial oxidation gas containing water vapor and ammonia. The knockout drum (35) comprises a bottom section (46) and top section (50) with a transfer means (53) connecting the bottom section to the top section. The top section comprises a series of trays (55) capable of channeling water from the upper end of the top section to the lower end of the top section. The transfer means provides unidirectional flow of a fluid from the bottom section to the top section.

Title: Recombinant construct for enhancement of gene expression in plants
Inventor: MOROZOV SERGEY
IPC: C12N15/67
Filed: 1998-05-28
Abstract: The present inventions focuses on the super-expression of foreign genes in transgenic cells by combining within a single cDNA construct and respective RNA transcript, several trans- and cis-acting genetic elements of viral origin which will act in concert to trigger the following functional events: a) the primary chimeric continuous RNA transcript is produced by the transformed cells from plant-expressible promoter (35S promoter); b) RNA  replicase produced by direct translation of the 5'-proximal gene of a single continuous primary transcript will synthesize secondary monocistronic (or dicistronic) mRNA as a result of the transcription from sgPr sequence. Expression of the 5'-proximal gene of these mRNAs will be enhanced by the .alpha..beta.-leader. Translation of the 5'-distal gene of dicistronic mRNA will be promoted by internal ribosome entry site (IRES) sequence derived from crTMV tobamovirus mentioned above; c) it is probable that at least part of RNA transcripts originated from sgPr will include at their 3'-end the minus copy of RNA replicase gene and genomic promoter for plus-RNA synthesis. It can be expected that RNA replicase produced in transgenic cell will bind with the 3'-terminal sequence of this RNA (genomic promoter) producing upon transcription the RNA molecules carrying the plus-polarity replicase gene at the 5'-end. Translation of these mRNAs will result in production of additional replicase in transgenic plant.
