Title: Continuous production of reduced gel content hydroxylated addition polymers
Inventor: ANDRIST KEVIN M
IPC: C08F220/28
Filed: 1995-10-13
Abstract: A process is disclosed for the continuous production, with reduced gel formation, of free radical addition polymers from ethylenically unsaturated monomers containing at least one free hydroxyl group such as 2-hydroxyethyl methacrylate, from about 0 to about 5% by weight of an alpha-beta unsaturated carboxylic acid such as acrylic acid or methacrylic acid, and the remainder of the monomers used are free radical addition copolymerizable compounds such as styrene, methyl methacrylate and butyl acrylate. The free radical addition polymerization is conducted at from about 150 DEG  C. to about 310 DEG  C. under superatmospheric pressure in the presence of one or more solvents. The solvent or the volume average of the solvent mixture has an overall calculated root mean square value of the hydrogen bonding and polar contributions of each solvent's solubility parameters in the range of from about 6 to about 15. The solvent or solvents in total have sufficient volatility under the conditions being used to conduct the polymerization such that any liquid condensate of vapor mixture forming on interior surfaces of the reactor equipment located above the surface of the monomer reactants contains at least 50 mole percent of the solvent to reduce gel formation on such interior surfaces. The process permits the continuous polymerization of the polymers over extended periods of time with reduced formation of gel particles and gel deposits.

Title: Quinazolines and pharmaceutical compositions
Inventor: TANG PENG CHO
IPC: C07D239/74
Filed: 1996-06-04
Abstract: The present invention relates to molecules capable of modulating tyrosine signal transduction to prevent and treat cell proliferative disorders or cell differentiation disorders associated with particular tyrosine kinases by inhibiting one or more abnormal tyrosine kinase activities. The present invention also provides pharmaceutical compositions and methods for inhibiting cell proliferation of differentiation and related disorders. Examples of such disorders include cancers, blood vessel proliferative disorders, psoriasis, hyperimmune response and fibrotic disorders. Example ofother disorders include the HER2 disorders, EGF disorders, IGFR disorders, PDGFR disorders, met disorders, SrC disorders, and KDR/FLK-1 disorders described herein. It is to be understood that compounds which are effective for diseases related to one TK will also likely be effective for diseases related to other TK's, especially those from the same family. Thus, for example, compounds shown to have good effect against Her2 are likely to also have good effect against other members of the Her family, i.e., EGFR, Her3,and Her4.

Title: Novel 3' terminal sequence of hepatitis c virus genome and diagnostic and therapeutic uses thereof
Inventor: KOLYKHALOV ALEXANDER A
IPC: C12N5/08
Filed: 1996-08-28
Abstract: The invention relates to the discovery of a novel RNA sequence at the 3' terminal sequence of hepatitis C virus (HCV) genome RNA. Included in the invention are the 3' sequence, its complement, and their use for nucleic-acid based diagnostics and for developing and evaluating novel anti-HCV therapies.  This sequence element, which is conserved among HCV genotypes, is likely to be essential for viral replication, and required for construction of full-length HCV  cDNA clones capable of yielding infectious RNA, progeny virus or replication-competent HCV replicons. Such functional clones are useful tools for evaluation of therapeutic approaches and as substrates for developing candidate attenuated or inactivated HCV derivatives for vaccination against HCV.

Filed: 1998-03-04
Abstract: Casting metal strip by delivering molten metal to a casting pool (81) supported on a pair of parallel casting rolls (16) and passing metal downwardly between the rolls to produce solidified strip (20). Flow of metal to the casting pool (81) is controlled by an input flow control valve (47). At start of casting when pool (81) is being filled speed of rolls (16) is varied in response to variations between actual instantaneous pool level and predicted level until pool approaches desired operational level. Thereafter any varia-tions between instantaneous roll speed and desired operational roll speed are caused to adjust valve (47) to being pool level and roll speed to desired operational valves.
Patent CA-2233974-A1 (CA)
Inventor: BRAATHEN COLIN WALTER
IPC: G01P5/24
Filed: 1996-10-17
Abstract: A method and device (60) is described which measures the speed of a flowing fluid (F) by measuring the difference in time taken for an ultrasonic signal to travel first upstream and then downstream in the fluid. In each direction the device (60) calculates the time taken for an ultrasonic wave packet emitted by one ultrasonic transducer (62) to be received by another (63). The method used consists of the digitisation (85) of the received waveform and the subsequent identification of waveform features by comparison with a standard template of the waveform. The position in time of these features is then determined with respect to a high speed clock (70). The results are then used in a weighted computation to determine the time of arrival of the waveform at the transducer (63).

Title: Effluent filtering apparatus
Inventor: KOTESKEY GARY L
IPC: B01D29/27
Filed: 1998-05-14
Abstract: An effluent filtering apparatus including an effluent filter fluidly connected to the output of an effluent pump disposed in an effluent tank, for providing filtered effluent to a drain field having a plurality of finger pipes defining a plurality of finger apertures. The effluent filter includes a tubular member defining a plurality of filtering orifices through a cylindrical wall. Effluent flows into the tubular member through an open first end and flows out of the tubular member through the filtering orifices, with turbulence within the tubular member preventing at least a portion of solid material present in the effluent from lodging within the filtering orifices. Effluent containing solid material smaller in size than the filtering orifices flows from the effluent tank to the drain field, but larger solid material present in effluent is filtered by the filtering orifices, with the filtering orifices remaining unobstructed for an extended period of time due to turbulent flow within the tubular member. A basket-like filter insert may be disposed within the tubular member proximate to the first end, defining a plurality of openings therethrough permitting flow of effluent but preventing solid material aggregated within the tubular member larger than the dimensions of the openings from flowing backwards from the tubular member and into the pump when the pump is deactivated.
