Title: Discontinuously expandable web materials
Inventor: DIVO MICHAEL
IPC: D04H13/00
Filed: 1999-05-05
Abstract: The present invention is a web material which can be used in the production of large quantities of articles which are assembled from, inter alia, continuously fed web materials. In particular, the web material of the present invention can be expanded by a predetermined amount whilst exhibiting a relatively low resistance to expansion. This material property is assessed in the Discontinuous Expansion Test which determines the Relative Expansion Tension reduction during the discontinuous expansion. A web material according to the present invention has a Relative Expansion Tension Reduction of at least 50 %. Another object of the present invention is the process for making such discontinuously expandable web materials comprising the step of incorporating longitudinal expansion means and optionally tearable expansion obstruction means into the web material.

Patent CA-2344569-A1 (CA)
Inventor: SMITH DONALD JOSEPH
IPC: E05B27/00
Filed: 2001-04-23
Abstract: The present invention relates primarily to the field of Locksmithing, wherein lock cylinders are stripped and re-assembled during re-combination.    In re-assembly the loading of pins and springs into the pin chambers of the cylinder shell is a difficult process entailing the manipulation of pins and springs within the confines of the cylinder's bore. Use of a top pin loader, whilst simplifying the process, still requires that springs be individually compressed as they are entered into the cylinder shell's bore. There is a clear need within the Locksmithing industry for a better means of loading the cylinder shell. The invention herein disclosed provides a practical means of rapidly loading the cylinder shell in two simple steps; the first being to compress the pins and springs into a carrier and transfer them smoothly into the cylinder shell; the second being to transfer them into the pin chambers of the shell.

Title: Telecommunication subscriber connection using a domain name system
Inventor: LAUSON DAVID J
IPC: H04L29/12
Filed: 1999-11-10
Abstract: A system and method for facilitating a telecommunication subscriber connection using a domain name system is disclosed. The system, which is part of a DNS  server, supports connection to a mobile terminal through a data network and includes multiple connections to external devices or systems, although one or more of the connections may be serviced by a single link. The connections link the system to the data network, to a home location register ("HLR") associated with the terminal and to a mobile switch associated with the terminal. Upon initiation of a query to the DNS server through the PDN, the DNS server signals the HLR for the identification of the switch that is associated with the mobile terminal. The HLR returns an identifier for the switch and the DNS  server then requests the switch to provide an address for the mobile terminal.  The switch establishes a connection with the mobile terminal and provides a temporary address through a network interface system such as an interworking function. The switch then returns this new address to the DNS server.
