Title: Tamper-evident slider bag
Inventor: CAPPEL CRAIG E
IPC: A44B19/16
Filed: 1999-07-01
Abstract: A plastic bag comprises opposing body panels (12, 14) fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. A  reclosable zipper (32) extending along a mouth portion formed opposite the sealed bottom of the plastic bag. The zipper is preferably free of graspable upper pull flanges in order to best accommodate a slider (32) and inhibit operation of the zipper without the slider (32). The slider (32) is mounted to the zipper for movement between a closed position and an open position. The zipper is closed while the slider is in the closed position. The zipper is opened in response to movement of the slider to the open position. To inhibit tampering with the contents of the bag, the bag includes a tamper-evident feature (40). In one set of embodiments, the tamper-evident feature (40) initially maintains the slider in the closed position and allows the slider to move away from the closed position toward the open position in response to removing or breaking the tamper-evident feature. In another set of embodiments, the tamper-evident feature initially maintains a mouth portion of the plastic bag in a folded position and allows the mouth portion to be unfolded in response to removing or breaking the tamper-evident feature.
Patent CA-2338145-A1 (CA)
Inventor: MIRAL KIM E
IPC: G06Q40/00
Filed: 2000-03-22
Abstract: L'invention concerne un système et un procédé d'échange de titres en réseau associant des économies d'échelle appréciées par les investisseurs institutionnels et les fonds de placement à la propriété directe de titres, ce qui permet à des investisseurs privés d'opérer sur le marché des obligations avec efficacité. Grâce à l'investissement d'équipe (600), on offre des économies d'échelle de niveau institutionnel à des particuliers en permettant à des groupes de particuliers d'acheter et de vendre des obligations en <= équipe >=, ce qui leur permet d'effectuer un échange rémunérateur sur le marché institutionnel au lieu de devoir procéder à de nombreux petits échanges sur le marché de détail, qui s'avère peu lucratif. De même, grâce au commerce de client à client (C2C), les clients peuvent négocier un échange directement entre eux au lieu de vendre leurs titres sur le marché intermédiaire. Le système et le procédé comprennent également une évaluation de risque automatique et une routine d'acceptation d'échange destinées à examiner une proposition d'échange d'un instrument financier reçu à partir d'un client sous forme électronique.
Patent CA-2338507-A1 (CA)
Title: Electronic ballast with frequency management
Inventor: CROUSE KENT E
IPC: H05B41/392
Filed: 1999-07-20
Abstract: A microprocessor controlled, electronic ballast operates a lamp at nominal settings and shifts the operation of the ballast away from nominal settings to reduce interference. The shift is randomized by a test -flip - [shift] routine that prevents all ballasts from attempting the same correction at the same time. On DC input voltage, the frequency of the boost controller (21) is varied to reduce EMI. The ballast operates in bands (91, 92, 93) according to the input voltage. Some bands correspond to full brightness, some to a fixed amount of dimming and some to a variable amount of dimming. In the event of an abrupt change in load, the microprocessor (31) changes the frequency of the inverter, thereby reducing output power and gradually unloading the boost circuit and maintaining power to the microprocessor.

Patent CA-2342538-A1 (CA)
Title: Optical fiber transmission system with polarization multiplexing to reduce stimulated brillouin scattering
Inventor: DELAVAUX JEAN-MARC PIERRE
IPC: H04B10/532
Filed: 2001-04-03
Abstract: A technique for suppressing stimulated Brillouin scattering SBS along an optical fiber signal path utilizes polarization modulation at the transmitter to split the launched power into orthogonal polarization states. By reducing the power along each polarization, SBS will be reduced. Linewidth broadening of the optical source is achieved by introducing: (1) a incoherence between the polarization states (using a time delay along the signal path of one polarization state); and (2) a frequency shift between the polarization states (using an acousto-optic modulator along the signal path of the remaining polarization state).

Abstract: A process of making a composite vessel with superior mechanical and aesthetic characteristics includes the steps of:  A) preforming a composite thermoplastic shell (41a) (e.g., by winding a commingled roving of fiberglass and a thermoplastic material onto a thermoplastic liner) having an opening for access to the interior B) placing the shell (which may optionally be preheated) into a mold (40) (which itself may optionally be preheated); C) introducing an inflatable bag (42) containing a heater (48) into the shell through the opening; D) heating the inflatable bag to a temperature which is sufficient to render the shell fluid while pressurizing the interior of the inflatable bag: E) continuing step D) until the shell forms against the interior walls of the mold; F) allowing the formed composite vessel to cool; G) removing the inflatable bag; and H) removing the formed composite vessel from the mold. Prior to step C), an insert (43) having an opening may be juxtaposed in alignment with the opening in the shell such that, during step C), the inflatable bag is inserted through the opening in the insert. If desired for the intended purpose of the composite vessel, a portion of the exterior surface of the insert may be threaded such that threads are formed in the opening of the shell whereby the insert can be unscrewed leaving a threaded po into the vessel.

Title: Hypodermic syringe with selectively retractable needle
Inventor: HOECK ROGER W
IPC: A61M5/315
Filed: 2001-08-03
Abstract: A hypodermic syringe with a selectively retractable includes an barrel having an proximal end and a distal end that defines a receiver with a shoulder. The barrel has a hollow bore therethrough and the receiver includes a plurality of inwardly projecting cams distal to the shoulder. There is an elongate plunger with a proximal end and a distal end sized to fit slidably within the bore of the barrel to define a chamber. There is a hub with a flange and a stem that has a passageway therethrough extending distally into the receiver. The stem has distal recesses disposed to engage the projecting cams so that the hub is retained with the distal end of the stem in the receiver. The syringe includes a needle mounted in the passageway in the hub with the distal point projecting distally and the fluid path communicates with the chamber. There is a clip about the elongate plunger initially allowing movement of the plunger for drawing and expelling fluid. When sufficient distal force is applied to the plunger moving and rotates the hub, the clip engages the barrel permitting only proximal movement of the plunger. The syringe includes a spring disposed about the stem compressed between the flange and the inward shoulder. When sufficient distal force is applied to the flange the hub is no longer retained. The spring urges a proximal movement into the barrel as the plunger is moved proximally.

IPC: A24D1/02
Filed: 2000-07-21
Abstract: The invention relates to a tobacco smoking article wrapper which selectively reduces the content of gaseous components in the smoke delivered during the use of the smoking article. The gaseous components can be low molecular weight aldehydes in the smoke produced during combustion/pyrolysis of the smoking article. The wrapper can comprise cigarette paper having an ammonium-containing compound filler therein for reducing the aldehyde content in the smoke. The ammonium-containing compound filler evolves ammonia upon combustion/pyrolysis of the smoking article which can chemically react with aldehydes in tobacco smoke and/or modify the combustion/pyrolysis reactions thereby reducing the initial formation of aldehydes to selectively reduce such aldehydes from the smoke inhaled by a smoker. The ammonium-containing compound can be magnesium ammonium phosphate used alone or in combination with one or more other fillers such as calcium carbonate.
