Title: Method for conversion of biomass to chemicals and fuels
Inventor: DAVISON RICHARD R
IPC: C12P7/54
Filed: 1998-06-12
Abstract: This invention provides a method for thermally converting volatile fatty acid (VFA) salts to ketones by mixing dry calcium salts of VFAs with hot heat transfer agent in an evacuated container, thereby causing thermal decomposition of the calcium salts of VFAs to form ketone-containing vapor and calcium carbonate; and separating the ketone-containing vapor from the calcium carbonate and heat transfer agent by condensing a mixture of ketones from the ketone-containing vapor. This invention also provides a process for conversion of VFA salts, produced by anaerobic fermentation of cellulosic biomass, into liquid fuels, volatile fatty acids, aldehydes, alcohols and lactic acid.

Title: A fluid diverter valve
Inventor: KARG JEFFREY A
IPC: F16K11/044
Filed: 1998-06-23
Abstract: A fluid diverter valve for selectively switching fluid flow between two paths is disclosed. The valve (200) includes an intake port (16), two output ports (17, 18), and a valve member (220) mounted for reciprocating movement between a first position wherein fluid is substantially prevented from flowing through the first output port, and a second position wherein fluid is substantially prevented from flowing through the second output port. The valve includes two switches (74, 276). Actuating one of the switches causes the valve member to move from the first position to the second position. Actuating the other switch causes the valve member to move from the second position to the first position. The disclosed valve acts as an integral diverter valve and vacuum break.

La morphologie cristalline est en outre caractérisée par une répartition autour du pic (ouverture angulaire totale à mi-hauteur de pic) d'environ 40· à 75·. Les nouveaux films présentent de préférence un allongement à la rupture dans le sens de référence d'environ 45 % à 90 %, de manière plus préférée d'environ 45 % à 80 %. De plus, les nouveaux films nécessitent une énergie de rupture inférieure à environ 350 N-cm/cm?2¿ lorsqu'on les rompt à l'aide d'un couteau de distributeur dentelé en métal, et inférieure à environ 70 N-mm/mm?2¿ lorsqu'on les rompt à l'aide d'un distributeur en polystyrène moulé par injection équipé d'un couteau dentelé en plastique. Enfin, les nouveaux films présentent un étirement inférieur à environ 4 %, de préférence inférieur à environ 3 % lorsqu'on les rompt au moyen de distributeurs de ruban disponibles dans le commerce.

Patent CA-2314515-A1 (CA)
Title: Flyless stream shingling and stream merging apparatus and method
Inventor: DESAULNIERS EDWARD
IPC: B65H29/66
Filed: 2000-07-24
Abstract: A machine assembly that receives like printed copies, one by one, or shingled, and/or nested, in one or two streams, to reforming said copies into a single-file stream of copies such that they may then be shingled into a single stream for further in-line finishing operations such as trimming and stacking. To reform two streams of copies into one stream, the copies of one stream must have a controlled and reasonably steady copy symmetry within itself and in relation to the other stream. The first operation of the machine assembly of this present invention is to create sufficient space between the copies of each stream such that the copies of the second stream may be deposited sequentially, on or between, the books of the first stream to create a single-file stream of copies with its own internal copy symmetry. This first operation applies whether the incoming streams are shingled or not and/or nested. The second operation is to open said copies into a single-file stream with a constant gap between said copies to monitor using the gap in real-time between copies in reference to a prescheduled norm and to use this data to set the relative surface speeds of the various sections of the machine assembly of these present inventions. The third operation of this machine assembly, its Flyless Shingling section, is to transition each copy of the single-file stream of copies (signatures or books) downward in a controlled fashion to reform same into a single shingled stream, the preferred copy configuration of the printing industry for the subsequent printing operations such as copy trimming, stacking or print-roll collection.

Title: Method and apparatus for dispensing liquids and solids
Inventor: CLARK TIMOTHY S
IPC: G05D27/02
Filed: 1999-02-24
Abstract: A system (Fig. 16) for metering and dispensing component liquids and solids has a microprocessor-based control system and progressive cavity pumps which provide accurate control of component ratios, shot sizes, flow rates and dispense durations. The system has feedback components (58, 66, 60, 68) for controlling the pressure, flow rates, fluid levels and amounts of fluids dispensed. The pressure in the flow system is used to control the pumps (34, 36) rather than a valved nozzle (49). The system may be used as a sprayer with compressed air added. Back and forth movement of the pump provides compensation for pressure changes. A mold charging system uses pressure to control the pumps which are cycled on and off to avoid overpressurizing the mold. The rate of pressure increase is used to control the rate of flow from the pumps as the mold approaches completion of the charge to avoid overpressurizing the mold.
Patent CA-2324284-A1 (CA)
Inventor: ANDERSON DAVID
IPC: C07K14/47
Filed: 1999-04-02
Abstract: The present invention is directed to compositions and methods comprising peptides which have a high affinity for each other and, when linked to a protein, are used to help fold the protein into a compact structure. By virtue of its stability and constraints, this scaffold can prolong the activity of any embedded protein sequences in the presence of cellular and other proteases. The compact structure can have other functional sequences embedded, and is preferable to linear and less constrained peptides for library screening, for creating structurally-biased peptide libraries and for targeting to specific intracellular and extracellular compartments. Compositions of the present invention can be displayed on the surface of viruses, archaebacteria, prokaryotic and eukaryotic cells for library screening, drug screening and display. Methods of the present invention are useful for screening in vivo for intracellular effector proteins modulating signaling pathways and to identify interacting proteins in vitro. Thus, the present invention is useful as a scaffold for gene therapy, for the isolation of new therapeutic drug leads and for potential use as a therapeutic in physiological fluids.

Abstract: Surface coverings with mechanical and chemical embossing, and methods of manufacture thereof, are disclosed. The surface coverings include a substrate, a foam layer disposed on the substrate, wherein the foamed layer has a chemically embossed pattern imposed therein, a wear layer disposed on the foam layer, and a mechanically embossed, cross-linked top layer disposed on the wear layer. In one embodiment, a web is formed including a substrate, a curable wear layer, an expandable foam layer between the substrate and the wear layer, and at least one inhibitor composition disposed as a pattern proximate the foam layer. The wear layer is coated with a cross-linkable top coat and then heated to a temperature at which the top coat is substantially cross-linked and cured, the wear layer is substantially cured, the foam layer substantially expands, and the pattern is chemically embossed to form a surface covering. Thereafter, the surface covering is tempered to a temperature above ambient temperature. The top coat is then heated and at least one surface texture is mechanically embossed and set thereon. The mechanical embossing can be performed in register with a printed or chemically embossed pattern of the surface covering. In one embodiment, the surface covering lacks the top coat and the wear layer is mechanically embossed.
