Patent CA-2307461-A1 (CA)
Inventor: SESSA EUGENE D
IPC: B05D7/14
Filed: 2000-04-03
Abstract: The present invention is directed to a process for the application of fluoropolymer to a preselected area of a threaded fastener, and particularly to substantially all of the threads of the fastener. The fluoropolymer is supplied to a spray nozzle in powder form and is subjected to a triboelectrostatic charging process so that individual  particles discharged from the spray nozzle are electrically charged. In the preferred form of the invention, the fluoropolymer powder is triboelectrically charged, entrained in an air stream discharged from the nozzle and directed onto the preselected area of the fastener. In this manner a generally uniform powder coating is deposited onto the preselected area of the fastener while the fastener is maintained at room temperature. Thereafter, t he fastener is heated to a temperature above the melting point of the fluoropolymer to thereby coalesce the deposited powder into a continuous film coating which adheres, upon cooling, to the pre-selected area of the fastener. In accordance with a preferred embodiment , the fastener is heated in a manner which raises the temperature of only the preselected area of the fastener to the fluoropolymer melting point. This preferred heating technique minimizes the retention of fluoropolymer inadvertently deposited on areas of  the fastener other than the preselected area, and allows this undesired fluoropolymer to be easily removed, even after heating.

Title: Network for providing switched broadband multipoint/multimedia intercommunication
Inventor: DEAVILA MIGUEL J
IPC: H04L12/56
Filed: 1998-11-10
Abstract: The present invention provides broadband multimedia communication over the standard circuit-switched public switched telephone network infrastructure (PSTN) and other physical or virtual circuit-switched infrastructures while simultaneously and transparently interoperating with the public Internet packet-switched infrastructure to effectively merge the capabilities of the two types of infrastructures into a seamless capability that can bring the benefits of using both types of existing switching infrastructures to large groups of users under the control of the same common and simple interface tools such as web browsers. The invention enables users to establish both packet-switched connections for sending or receiving content for which low-latency and unpredictable response times are not a problem (i.e. text, small graphics, e-mail, small file transfers); and circuit-switched connections for sending or receiving content that benefits from streaming data at fixed data rates, without contention for bandwidth from other users during a communication session, (i.e. video, voice, complex graphics and animations, or large file transfers). The broadband network of the present invention thus mates the convenience of point and-click on-demand Internet-type packet-switched connectivity with the continuity of a circuit switch connection, and bundles B channels, or controls connections on virtual circuit switches such as ATM or RSVP for the required bandwidth on-demand for video conferencing and other high-bandwith applications.

IPC: B63B35/79
Filed: 2000-08-25
Abstract: A canoe carrying pad is disclosed for use in the carrying (portaging) of a canoe by a single person. Canoes are normally turned upside down for carrying and placed and the user's shoulders by way of the carrying thwart (yoke) of the canoe. In doing such, the weight of the canoe is transferred onto the shoulder and neck area of the user. The resulting pressure on the user's body creates various levels of discomfort caused by the weight of the canoe, and a lack of fit of the thwart with the user's neck and shoulder area. The pad of this invention helps to essentially eliminate the discomfort to the user in the shoulder and neck area. The pad includes a pre-shaped padding material which is enwrapped in fabric material and has attachment straps which permit the ease of installation and removal of the portage pad to and from the carrying thwart (yoke). The portage pad is shaped and constructed such that when attached to the thwart (yoke) it will provide maximum contact with the user's neck and shoulder area to reduce localized pressure points. The padding is composed of material that will conform to the anatomical contours of the shoulder and neck area.

Abstract: A technique for bonding soft biological tissue (2) having an incision (4) therein with forceps (8) adapted to grip a portion of the tissue on both sides of the incision. Electrodes (11) are secured to the forceps for contacting the tissue portion. An electrical power source (12) provides a high frequency electrical signal to the electrodes to be passed through the tissue portion. The electrical power source is controlled to provide the electrodes with one voltage signal during a first of two stages, and another voltage signal during a second of the two stages. During the first stage the voltage rises linearly. During the second stage the voltage is stabilized, and is modulated with a low frequency rectangular signal. A clamping means applies force with the forceps to compress the tissue at one level or at different levels during two time periods while the high frequency voltage is passed through the electrodes. The tissue impedance is measured as a function of time with its minimal value being determined, and stored.
