Title: Polymerization process controller
Inventor: HAVLENA VLADIMIR
IPC: C08F2/00
Filed: 1998-06-26
Abstract: A batch polymerization process controller using inferential sensing to determine the integral reaction heat which in turn is used to indicate the degree of polymerization of the reaction mixture batch. The system uses a reaction temperature compared with a desired temperature, and the result is used as a feedback to monitor and control the process. One version of the process controller also uses a feedforward signal which is an integral reaction heat indication from a process model. In another version of the process controller, the integral reaction heat is compared with a desired integral reaction heat, and result is used as another feedback to monitor and control the process. Heat production and reaction temperature profiles may be used, along with the thermokinetic equations to determine the polymerization process and reactor models which are utilized by the process controller to optimize the polymerization process in terms of efficient use of cooling water and desired polymerization of each mixture batch.

Title: A metering device for paint for digital printing
Inventor: ANDERSON DEAN ROBERT GARY
IPC: B05D1/02
Filed: 1998-06-10
Abstract: A paint injector (10) for digital printing in which paint is deposited in metered amounts on a print medium (69) comprises a wheel (13) rotatable by a shaft (15) of a motor (48), an idler (34) disposed in a paint reservoir (24), and an endless cable (36) disposed around the wheel (13) and the idler (34).  The motor (48) is preferably computer controlled (57) such that the rotation of the wheel (13) and thus movement is selectively controlled. As the wheel (13) is rotated, paint contained within the paint reservoir (24) coats the cable (36) and is thus drawn by the cable (36) in front of the air stream (67). The air stream (67) pulls the paint from the cable (36) and carries it toward the print medium (69). By employing a plurality of such paint injectors (10) into a single print head, each containing a different color of paint, and secured to a computer controlled, movable carriage (16) positioned over the print medium (69), a digital image can be painted by the print head on the print medium (69).

Patent CA-2298957-A1 (CA)
Title: Advantageous use of battery mass in electric watercraft
Inventor: MOTSENBOCKER MARVIN ANDREW
IPC: B63B1/10
Filed: 2000-02-15
Abstract: Electric powered watercraft that lack an open-hull capsizable design utilize a low energy density heavy power supply for stabilization. The power mass is enclosed in one or two torpedo-like structures that are mostly or completely submerged. The structure(s) are combined with at least one enclosed float, preferably of convex shape. A  platform is spaced above the float(s) via struts that allow wave energy to pass through the watercraft rather than collide with large vertical surfaces. The design also minimizes wake formation. This configuration of a low-energy density power supply, particularly within tapered hull(s) is useful for electric powered houseboats and personal pleasure craft that can withstand stormy conditions more easily than equivalent sized open vessel designs.

Title: Hypersensitive response elicitor from erwinia amylovora, its use, and encoding gene
Inventor: BEER STEVEN V
IPC: C12N15/52
Filed: 1998-07-24
Abstract: The present invention is directed to an isolated protein or polypeptide which elicits a hypersensitive response in plants as well as an isolated DNA molecule which encodes the hypersensitive response eliciting protein or polypeptide. This isolated protein or polypeptide and the isolated DNA molecule can be used to impart disease resistance to plants, to enhance plant growth, and/or to control insects on plants. This can be achieved by applying the hypersensitive response elicitor protein or polypeptide in a noninfectious form to plants or plant seeds under conditions effective to impart disease resistance, to enhance plant growth, and/or to control insects on plants or plants grown from the plant seeds. Alternatively, transgenic plants or plant seeds transformed with a DNA molecule encoding a hypersensitive response elicitor protein or polypeptide can be provided and the transgenic plants or plants resulting from the transgenic plant seeds are grown under conditions effective to impart disease resistance, to enhance plant growth, and/or to control insects on plants or plants grown from the plant seeds.

Patent CA-2306234-A1 (CA)
Title: Catalyst support, catalyst, reactor for hydrogenation reaction, and catalytic reaction method
Inventor: NAKAMURA KENJI
IPC: C10G49/00
Filed: 1998-10-14
Abstract: A catalyst carrier composed of a refractory inorganic oxide has a rotationally symmetrical shape having a hollow portion, such as a doughnut shape. An outer peripheral surface and the inner peripheral surface separating the hollow portion are linked by curved surfaces, and the height h of the carrier along the rotational symmetry axis is less than the outer diameter D 0 of the carrier. Using a catalyst having this carrier shape for a fixed bed makes it possible to prevent granular substances from causing catalyst plugging, and catalyst life can be extended because the catalyst-induced differential pressure increase is low even when granular substances accumulate on the catalyst.      It is also possible to prevent the reaction fluid from undergoing channeling. Also provided is a hydrogenation reactor whose fixed bed is packed with the catalyst.

Title: Make-your-own cigarette
Inventor: BRACKMANN WARREN A
IPC: A24C5/40
Filed: 2000-06-14
Abstract: A non-smokeable cigarette unit which may be rendered smokeable by application of a tubular sleeve to the cigarette filter region has a tobacco rod, a filter plug portion and connecting material for connecting the filter plug to the tobacco rod. At least a portion of the periphery of the filter plug is of a sufficient porosity to render the cigarette unit unsmokeable. The filter has a diameter less than the diameter of the tobacco rod. The connecting material bridges a transition from the smaller filter to the larger tobacco rod. This transition portion assists in sliding the sleeve onto the larger tobacco rod to provide a smokeable cigarette.

Title: Manufacturing a dental implant drill guide and a dental implant superstructure
Inventor: POIRIER MICHEL
IPC: A61B6/14
Filed: 1997-12-18
Abstract: Dental implant drill holes and the shape of a dental implant superstructure are chosen by creating a computer model giving jawbone structural details, gum surface shape information and proposed teeth or dental prosthesis shape information. The computer model shows the bone structure, gum surface and teeth images properly referenced to one another so that implant drill hole positions can be selected taking into consideration proper positioning within the bone as well as proper positioning with respect to the dental prosthesis. Similarly, manufacture of the dental implant superstructure used for fixed dental prosthesis or overdentures can be designed based on knowledge of the actual implant positions referenced to an image of the gum surface and proposed dental prosthesis.

Title: Application of enzyme prodrugs as anti-infective agents
Inventor: SHEPARD H MICHAEL
IPC: A61P31/04
Filed: 1998-12-22
Abstract: The present invention provides a method for targeting toxic antimetabolites to gram negative infections. It provides a means of taking advantage of a key disease resistance mechanism to activate these drugs locally, and to overcome the resistance phenotype of the microbes. The invention further provides a method for selecting for antibiotic sensitivity, since a likely mechanism by which organisms are likely to gain resistance to the prodrugs is via loss of enzyme activity, which will make the bacteria sensitive to antibiotics once again.
