Patent CA-2281291-A1 (CA)
Inventor: ARDITO MARCO
IPC: G03F1/00
Filed: 1999-09-02
Abstract: A method of surface etching silica glass. The method comprises depositing a layer of electrically conductive material on a silica glass substrate with a surface to be etched. A pattern reproducing the etching pattern to be fabricated on the substrate surface is formed on such conductive material through deposition, exposure and development of a resist, by leaving uncovered the areas of said conductive material layer corresponding to the areas of the substrate to be etched. As a conductive material, a material such as titanium is chosen, which can be etched by the same etching medium, such as CHF3, used for etching the substrate. The removal of said conductive material layer and the etching of the substrate in the areas left uncovered by the resist are then performed in a single step.

Filed: 1999-09-02
Abstract: A system and method of use to help a person to stop or modify an adverse habitual health-related behavior, e.g., smoking, weight control, stress management, etc., by following a calculated regimen to commence on a day to be selected by the person. The system comprises a computer and a series of customized visually perceptible messages establishing a customized regimen to aid the person to stop or modify the adverse habitual health-related behavior. The computer is arranged to receive personal information about the person and which is relevant to the behavior and makes use of expert system software to provide the customized messages in response thereto. The customized messages are in the form of a daily sequence measured relative to day selected by the person for the regimen to begin. Each of the messages is arranged to be read by the person in sequence on a daily basis and includes respective numerical indicia representing the number of days from the selected day to the day of said message. The messages are provided to the person in various ways, e.g., delivered to the person on a daily basis by means of some electronic communication medium, such as the Internet, e-mail, facsimile, etc., where they are printed out by the person.  Alternatively, the cards or sheets may be generated by the system and provided to the person in hard copy form. The messages produced by the system may be updated and modified based upon information provided to the system by the person. Moreover, messages may be provided by the system to a support person to aid the person wishing to change his/her health-related behavior.

Title: Variants of ciliary neurotrophic factor with enhanced receptor selectivity and method for their selection
Inventor: DE MARTIS ANNA
IPC: A61P25/00
Filed: 1998-03-20
Abstract: The subject of the present invention are variants of ciliary neurotrophic factor with enhanced receptor selectivity (CNTFR), useful for the treatment of diseases and disorders including motor neuron diseases and muscle degenerative diseases. Another subject of the invention is to provide a method for identifying the above mentioned CNTF variants. The hCNTF variants with the amino acid substitutions in accordance with the present invention, have a reduced ability, as compared to the human CNTF, to elicit biological effects through soluble CNTFR, without affecting its ability to activate membrane-bound neuronal CNTF receptors, thereby improving its therapeutic properties.  Fig. 1 shows the reduced CNTFR binding affinity of a CNTF variant according to the invention (IA-CNTF; SEQ ID NO:2). It is evident that the binding affinity of this variant to the CNTFR is reduced as compared to the wild-type human CNTF molecule.

Title: Flange feeder for wooden i-beam assembly machine
Inventor: CROSTON VICTOR W
IPC: B27M3/00
Filed: 1999-09-29
Abstract: A flange feeder utilizes a pair of left and right handed gripper assemblies mounted to an overhead horizontal transport drive to successively convey a pair of flange members into overhead vertical alignment with left and right handed infeed sections of a longitudinal conveyor leading into a chords and webs assembly machine. The pair of flanges are successively conveyed from a lateral flange conveyor into two or more sets of rotating grippers mounted on a common rotating shaft. The arrangement of the grippers to simultaneously grip or release a flange enables flange stock to be gripped, rotated, transported and then fed into the infeed conveyor in positively controlled and predictably oriented manner.

Abstract: Apparatus for a home workshop to collect wood dust from a plurality of locations and deposit the dust in a central container. The apparatus consists of a tubing manifold, running along the wall of the workshop, with multiple connection points for tools. The manifold contains a vacuum tee fitting that allows the vacuum source to be connected in the middle of the manifold, rather than at one of the ends, without sacrificing collection efficiency. This reduces the average length of the suction path to the tools, further enhancing collection efficiency, and allows location of the vacuum source where convenient.
