Patent CA-2379384-A1 (CA)
Inventor: HAMMONDS CARL L
IPC: B01F13/08
Filed: 2000-07-13
Abstract: Apparatus and method for dissolving chemical tablets (5) for creating a variable rate of chemical dissolution in a stream of constant flow rate of untreated liquid, especially water. The apparatus includes a housing (12) in which a container (20) is placed. The container (20) includes a sieve plate or perforated grid (28) which separates the container (20) into an upper chamber (30) in which chemical tablets (5) are stored and a lower mixing chamber (32).  A collection reservoir (26) is defined in an annular region outside the container wall (22) and inside of the housing ( 12).  Several arrangements are illustrated by which a vortex of liquid is generated of controllable variable intensity in the lower or mixing chamber (32) thereby creating uneven liquid pressure beneath the perforated grid (28) as a function of radial distance. As a result, fluid passes aggressively through outer radial perforations or holes (30) in the grid (28).

Title: Method and device for desalting water
Inventor: WOBBEN ALOYS
IPC: B01D61/06
Filed: 2000-03-18
Abstract: The invention concerns a method for desalting water by reverse osmosis, in particular for desalting sea water, whereby salt water at a first pressure level is introduced into a pressure compensating device, and is conveyed from the pressure-compensating device at a second, higher pressure level into a membrane module, whereby desalted water and concentrated salt water are discharged from the membrane module. In order to increase the efficiency and consequently the energy balance of such a method, the invention proposes to continuously introduce the concentrated salt water, which has been discharged from the membrane module, at a second pressure level into the pressure-compensating device, wherein it is used to subject the salt water introduced into the pressure compensating device to the second pressure level, and to discharge the salt water and convey it to the membrane module. The invention also concerns a device for implementing this method.

Title: Mutated il-13 molecules and their uses
Inventor: JOSHI BHARAT H
IPC: A61P35/00
Filed: 2000-11-10
Abstract: The present invention provides antagonists and agonists of IL-13 activity. The antagonists comprise a mutation in which the glutamic acid at position 13 of the IL-13 molecule is changed to a neutral or a positively charged molecule.  The antagonists can be used to reduce or end symptoms in conditions, such as asthma, allergic rhinitis, atopic dermatitis, and hepatic fibrosis in schistosomiasis, in which IL-13 is an initiator, mediator, or enhancer of the abnormal state. Additionally, the antagonists can be used to slow the growth of cells of cancers for which IL-13 is an autocrine growth factor. Such cancers include renal cell carcinoma, Kaposi's sarcoma, and Hodgkin's disease.  The agonists comprise mutated IL-13s in which one or more of the residues at positions 112, 110, 109, 92, 69, or 66 are mutated to a neutrally charged residue, or one with a charge opposite to the charge of the residue found at that position in native IL-13, provided that the residue at position 13 of the molecule is not negatively charged. The agonists can be used as more potent agents to provoke an effect provided by IL-13. In particular, the agonists can be used as reagents in the maturation of monocytes into dendritic cells, or to pretreat bone marrow stem cell donors to reduce graft versus host disease in the recipient of the stem cells. Finally, the invention provides IL-13 receptor binding molecules with affinity for the IL-13 receptor at least about 3 times greater than that exhibited by wild-type IL-13. Also provided are methods and compositions for specifically delivering an effector molecule to a tumor cell by chimeric molecules comprising the effector molecule and an IL-13 receptor binding molecule, and pharmaceutical compositions comprising such chimeric molecules.

IPC: H04N7/30
Filed: 2001-01-12
Abstract: A method of encoding and compressing a video sequence, for transmission across a video channel, includes converting the original sequence of frames (O) to a compressed sequence (C) which includes intra-frames, predicted frames and interpolated frames. A sequence of residual images (R) is then determined by subtracting the original frames from the compressed frames. Finally, a spatial/temporal transform is applied to the residual image sequence, the output of which is transmitted across the video channel from the video encoder to a video decoder. A similar approach, using a temporal transform on the residuals, may be applied to audio compression.
