Title: Techniques for dispensing postage using a communication network
Inventor: LEON J P
IPC: G06Q20/00
Filed: 2000-11-07
Abstract: Techniques for dispensing postage using a communication network such as the Internet. A postage vendor system (PVS) is assigned a single postal license number by a postal authority, such as the USPS, and is used by the PVS to cater to postage requests from a plurality of unrelated users who may be at different geographical addresses. The PVS may comprise a plurality of server systems and may receive requests to purchase stamps from one or more user systems. In response to the postage purchase requests, the PVS may generate information for printing indicia corresponding to the stamp requests based upon the single postal license number associated with the PVS. The PVS may then communicate the information for printing the indicia to the one or more user systems. The user systems may print the indicia based upon the information for printing the indicia received from the PVS.

Title: Generating a non-reproducible printed image
Inventor: TAME GAVIN RANDALL
IPC: G07D7/12
Filed: 2001-03-14
Abstract: A method of generating a non-reproducable printed image, for example on a cheque, involves printing a first, background layer of ink on the document, and then printing data on top of the background layer. The ink used to print the background layer is reflective of light of a predetermined wavelength, typically in the infra red spectrum. The ink used to print the data is visually indistinguishable from the first ink, but absorbs light in the infra red spectrum, so that when the printed image is illuminated with infra red light, the image can be discerned.

Patent CA-2432013-A1 (CA)
Inventor: NICHOLSON ALLAN
IPC: H01R43/00
Filed: 2001-12-20
Abstract: An electrical connector and method of making the electrical connection are disclosed for use in particularly arduous conditions, such as down hole oil production applications. The invention provides high electrical integrity with an ability to accommodate steady and/or fluctuating mechanical forces placed via the cable into the connector. Synergy between the mechanical and electrical aspects of the design is taught in which an insulating member, fitted with annular upstands, co-operates with a mechanically soft, essentially incompressible, insulating substance (gel) to cause vibrations in the cable to be dissipated over a length of the insulated cores inside the connector rather that at a single point where it would cause the core to fracture. In addition, annular collars of the gel are provided between the insulating member and the crimped pin-core connections and between the annular upstands and insulated cores to give further cushioning. Because the core insulation sits deep inside the annular upstand of the insulating member and gel collars, this creates a good electrical interface with a long creepage distance. The method covers the creation of the gel collars, alignment of contact pins and insulated cores and assembly of the connector.
