Title: Image revealing squeegee device for an electrocoagulation printing apparatus
Inventor: DAVIDSON NORMAND
IPC: B41C1/10
Filed: 1997-12-10
Abstract: An image revealing squeegee device for an electrocoagulation printing apparatus including a positive cylindrical electrode having a central longitudinal axis and a passivated surface on which dots of colored, coagulated colloid representative of a desired image are formed by electrocoagulation of an electrolytically coagulable colloid present in a colloidal dispersion containing a coloring agent, the positive electrode having a predetermined radius and being rotatable about the longitudinal axis in a predetermined direction.  The squeegee device of the invention comprises an elongated blade member of resilient material having two planar surfaces intersecting one another to define a rectilinear edge extending parallel to the longitudinal axis of the positive electrode and adapted to contact the surface thereof, one of the planar surfaces defining a colloid arresting surface for retaining upstream of the blade member excess colloidal dispersion carried by the positive electrode and containing non-coagulated colloid, the colloid arresting surface being inclined in a direction opposite to the direction of rotation of the electrode at an angle of about 100° to about 160° relative to the radius thereof, and means for holding the blade member in pressure contact engagement with the positive electrode.  Upon rotation of the positive electrode, non-coagulated colloid contained in the dispersion is retained by the colloid arresting surface, thereby uncovering the dots of colored, coagulated colloid without adversely affecting the coagulated colloid.

IPC: G16B20/20

Abstract: Normalization of experimental fragment patterns for nucleic acid polymers having putatively known sequences starts with obtaining at least one raw fragment pattern for the experimental sample. The raw fragment pattern represents the positions of a selected nucleic acid base within the polymer as a function of migration time or distance. This raw fragment pattern is conditioned using conventional baseline correction and noise reduction technique to yield a clean fragment pattern. The clean fragment pattern is then evaluated to determine one or more "normalization coefficients". These normalization coefficients reflect the displacement, stretching or shrinking, and rate of stretching or shrinking of the clean fragment, or segments thereof, which are necessary to obtain a suitably high degree of correlation between the clean fragment pattern and a standard fragment pattern which represents the positions of the selected nucleic acid base within a standard polymer actually having the known sequence as a function of migration timeor distance. The normalization coefficients are then applied to the clean fragment pattern to produce a normalized fragment pattern which is used for base-calling in a conventional manner. This method may be implemented in an apparatus comprising a computer processor programmed to determine normalization coefficients for an experimental fragment pattern. This computer may be serapate from the electrophoresis apparatus, or part of an integrated unit.

Title: Hydraulic system having boost pump in parallel with a primary pump, and a boost pump drive therefor
Inventor: MEMORY RUSSELL JAMES
IPC: F04B41/06
Filed: 1998-05-01
Abstract: This invention pertains to hydraulic systems for agricultural implements whereby two or more fluid power sources are combined in parallel. Total fluid capacity is increased so that one source may have reserve capacity for serving other loads. Flow controls for the system are set so that one source maintains at least a minimum flow to a load when the flow provided by the other source diminishes. Specifically, an aircart fan is operated by fluid power combined from a tractor source and a ground driven pump source with controls being provided to control the fan speed and proportions of flow from each source. The ground driven source (boost pump) boosts available fluid power volume to meet demands of the aircart fan. The boost pump is located near the aircart fan and connected with short lines to minimize power loss in the lines. The boost system shares the tractor components for fluid reservoir, filtering, and cooling so that it does not require its own such components.

Title: System for providing an interactive response to direct mail
Inventor: SHANE TERENCE MARTIN
IPC: G06Q30/02
Filed: 1998-05-25
Abstract: A system for providing an interactive response to direct mail programs comprises a recipient database, a mail generator, and a web server computer operationally connected through the Internet to remote computers accessible by direct mail recipients. The recipient database stores data records containing addressing information such as the name, mail, fax or e-mail address, and a unique personal identification code for each direct mail recipient. The mail generator retrieves recipient data from the database and generates a multiplicity of direct mail pieces each displaying the name, address, and a uniform resource locator containing the personal identification code for one recipient. A responding recipient accesses the web server computer by entering the uniform resource locator displayed on the direct mail piece into a web browser on a remote computer. The web server computer retrieves recipient data from the recipient database correlated to the personal identification code contained in the uniform resource locator and uses this recipient data to create a unique interactive web page.

Title: Non-toxic mutants of pathogenic gram-negative bacteria
Inventor: APICELLA MICHAEL A
IPC: A61K39/02

Patent CA-2247542-A1 (CA)
Inventor: NYGARD STINA
IPC: D21H19/38
Filed: 1998-09-16
Abstract: The present invention concerns a method for producing a base paper for fine papers, the base paper being produced from a mixture of a mechanical pulp and a chemical pulp. The chemical pulp used comprises a chemical softwood pulp having a elastic modulus close to that of the mechanical pulp and a great bonding strength. It is preferred to use a chemical softwood pulp which produces a sheet having a elastic modulus of less than 6000 N/mm2 when the bonding strength is 400 J/m2. A pulp of this kind has a goodScottBond strength at the same light scattering. The base paper produced by the method can therefore be used in double-coated fine papers which require a large bonding strength of the base paper.
