Title: Swabbable needleless low reflux injection port system
Inventor: RYAN DANA WM
IPC: A61M39/04
Filed: 1999-10-01
Granted: 2008-04-15
Abstract: A needleless IV injection port assembly (100) includes a spiked body (102) provided with a hollow spike (104), a female luer component, a flexible and resilient spike boot (108) having a tip (170) and spring portion (172), a centering member (110), and a resilient swabbable septum (112). When a separate male luer is positioned over a protuberence on the septum (112) and pushed into the female luer component, the male luer urges the septum (112) toward the spike (104), causing the spring portion (172) of the boot (108) to be compressed and the tip portion (170) of the boot to be pierced by the tip of the spike (104). The injection port causes minimal reflux, and the spike boot (108) and septum (112) provide a swabbable antibacterial double barrier over the spike (104).

Title: Fault location in a telecommunications network
Inventor: DRURY IAN RICHARD
IPC: H04M3/30
Filed: 2001-03-29
Granted: 2007-06-19
Abstract: A fault is located along a telecommunications line between the network terminating equipment and the local exchange by measuring a change in the capacitance of the line when compared with the capacitance under normal operating conditions. A geographical information system is used to plot all possible routes for the line between the terminating equipment and the exchange, and the most probable route is selected based on the known positions of nodes along the line, such as pole mounted distribution points and streetside cabinets. The distance of the fault along the line is then plotted along the most probable route to determine an accurate fault location, which is given to a field technician as the location of the nearest premises or a grid reference.

Patent CA-2439552-C (CA)
Inventor: FIELD STEPHEN
IPC: B29C65/02
Filed: 2002-06-07
Granted: 2005-02-08
Abstract: Vibratory welded connections are formed between first and second members (32, 33) of thermoplastic material by interposing a junction piece (47) of similar material and vibrating the junction piece (47) at high speed while pressing the first and second members (32,33) in a controlled manner against opposite sides of the junction piece (47). Friction created by the vibration generates heat which melts a small amount of material at the engaging surfaces which upon cooling provides a strong welded joint having minimal flash. Entire frame systems such as window frames can be fabricated by an apparatus system (120) which forms a friction welded joint between adjacent ends of the frame members (134, 135, 136, 137). Furthermore the frame can be fabricated around a panel such as a glazing panel. The welded connections formed by the system do not mar the finish of the frame members and produce no unsightly flash bead requiring subsequent machining steps for its removal.
