Patent CA-2262853-A1 (CA)
Title: Stable, concentrated solutions of high molecular weight polyaniline and articles therefrom
Inventor: MATTES BENJAMIN R
IPC: H01B1/12
Filed: 1997-05-29
Abstract: Stable, concentrated solutions of high molecular weight polyaniline. In order to process high quality fibers and other articles possessing good mechanical properties, it is known that solution concentrations of the chosen polymer should be in the range from 15-30 % (w/w). Moreover, it is desirable to use the highest molecular weight consistent with the solubility properties of the polymer. However, such solutions are inherently unstable, forming gels before processing can be achieved. The present invention describes the addition gel inhibitors (GIs) to the polymer solution, thereby permitting high concentrations (15 % (w/w)) of high molecular weight ((Mw)120,000, and (Mn)30,000) emeraldine base (EB) polyaniline to be dissolved. Secondary amines have been used for this purpose in concentrations which are small compared to those which might otherwise be used in a co-solvent role therefor. The resulting solutions are useful for generating excellent fibers, films, coatings and other objects, since the solutions are stable for significant time periods, and the GIs are present in too small concentrations to cause polymer deterioration. It is demonstrated that the GIs found to be useful do not act as co-solvents, and that the gelation times of the solutions are directly proportional to the concentration of GI. In particular, there is a preferred concentration of GI, which if exceeded causes structural and electrical conductivity degradation of resulting articles. Heating of the solutions significantly improves solubility.

Patent CA-2272281-A1 (CA)
Title: Collector apparatus and method
Inventor: MOSER JAMES R
IPC: B65H31/30
Filed: 1997-08-26
Abstract: The invention is directed to a collector apparatus and method for collecting and advancing sheet articles in high speed media processing. A conventional collecting apparatus includes a collector plate with continuously running transport belts for advancing and collecting the sheets, movable stop brackets for stopping the sheets on the collector plate, and upper idler drop rollers for pressing the collected sheets against the belts to facilitate movement of the collected sheets. The conventional apparatus maintained continuous contact between the collected sheets and the continuously running sheets, leading to smearing of toner on the sheets and limited the sheet collecting capacity of the apparatus. The present invention overcomes these drawbacks by selectively inhibiting contact between the collected sheets and the transport mechanism.  The collecting apparatus (10) includes a collector plate (12) having a sheet collection surface (14); movable stop brackets (20A, 20B) for temporarily stopping sheet advancement; upper idler stop rollers (52A, 52B) movable toward the collector plate; and a transport mechanism (B1, B2) movable through an opening in the collector plate to selectively advance the sheets.

IPC: C12N5/08
Filed: 1997-11-19
Abstract: Genetic modification of pluripotent hemopoietic stem cells of primates (P-PHSC) by transduction of P-PHSC with a recombinant adeno-associated virus (AAV). The genome of the recombinant AAV comprises a DNA sequence flanked by the inverted terminal repeats (ITR) of AAV. The DNA sequence will normally comprise regulatory sequences which are functional in hemopoietic cells and, controlled by these regulatory sequences, a sequence coding for a protein or RNA with a therapeutic property when introduced into hemopoietic cells. Preferred examples of DNA sequences are the human lysosomal glococerebrosidase gene, a globin gene from the human .beta.-globin gene cluster, a DNA sequence encoding an RNA or protein with anti-viral activity, the .alpha. 1-antitrypsin gene and the human multidrug resistance gene I (MDRI). The invention provides for effective gene therapy with PHSC of primates, in particular humans.

IPC: G01R31/58
Filed: 1999-06-29
Abstract: A fault indicator contained within a protective equipment closure of the type used to house pad-mounted components of a power distribution system detects the occurrence of a fault current in a monitored conductor and provides a light indication thereof. The fault indicator includes a circuit monitoring module, having an integral fault indicator flag module, and a remote fault indicator light module. A status-indicating flag is rotatably mounted in the integral fault indicator flag module. The flag is positioned in either a reset indicating position or a fault indicating position by a magnetic pole piece, which is magnetized in one magnetic direction or the other by momentary application of a current in one direction or the other to an actuator winding on the pole piece. A magnetically actuated reed switch in an auxiliary magnetic circuit comprising an auxiliary pole piece magnetized by the actuator winding and a bias magnet magnetically aligned to oppose the reset magnetic orientation and reenforce the trip magnetic orientation of the magnetic pole piece closes upon occurrence of the fault current to connect an internal battery to an LED contained within the remote fault indicator light module so that the LED is visible from the exterior of the protective equipment enclosure. The light indication of the fault occurrence may be reset automatically by a timed reset circuit, which includes a timing capacitor, or manually by a manual reset circuit, which includes a magnetically actuated switch housed in the remote light module and connected across the timing capacitor.

Title: Automatic setup of services for computer system users
Inventor: CHANG LINDA Y
IPC: H04L12/24
Filed: 1997-06-18
Abstract: Various services within a computer system are automatically set up as users are added to the system through a directory service (420). A user template (506) is selected that already contains default settings (530-540) for each of the services available on a system such as e-mail and a web service. Various user templates exist and contain different default settings for each available service depending upon the user. Default settings from each service (504) are copied onto a new user form (508). Next, default settings from the selected user template are copied to the new user form and override any conflicting default settings from the services. The default settings from the new user form are used to automatically set up and enable each service for the new user. The data from the new user form is copied into a central account database (300) that contains rows (305) of user information, with columns (314-322) corresponding to a particular service. Each user is automatically enabled for use with available services including an e-mail account and a generated web page. When an individual user then logs on to the computer system, the services available have already been set up for that individual user. If the user has any special privileges such as being an administrator, webmaster, or a postmaster then that user may begin performing that role.

Patent CA-2284673-A1 (CA)
Title: An antenna and a feed network for an antenna
Inventor: TASSOUDJI ALI
IPC: H01Q1/36
Filed: 1998-03-25
Abstract: An area-efficient network is configured such that a section of the feed network (1804, 1808) is disposed on a radiator portion of an antenna (1304, 1308) and the remainder of the feed network is disposed on a feed portion. Because part of the feed network is disposed on the radiator portion, the remainder of the feed network requires less area on the feed portion. As a result, the feed portion of the antenna can be smaller as compared to antennas having conventional feed networks. Preferably, the traces of the feed network that are disposed on the radiator portion are disposed opposite the ground portion of the radiators. As such, the ground portion of the radiators serves as a ground plane for this part of the feed network. The area-efficient feed network can be implemented with numerous different types of antennas of varying configurations, including single-band and multi-band helical antennas. As a result of this configuration, the overall size of the antenna and the amount of loss in the feed are reduced as compared to antennas having conventional feed networks.
