Inventor: TUROCK DAVID L
IPC: H04L12/66
Filed: 1996-10-29
Abstract: A method and apparatus are provided for communicating audio information over a computer network (214). A standard telephone (202) connected to PSTN (210) can communicate with any other PSTN-connected telephone (204), where a computer network, such as the Internet (214), is the transmission facility instead of conventional telephone transmission facilities. The caller dials the number of an access port (206) for the computer network and transmits the number of the called party when connected to the port. The port receives the number of the called party and establishes a two-way, full-duplex communication link via the computer network (214) to a corresponding remote access port or specialized computer system (216) in the vicinity of the called party (204). The port at the receiving end is connected to the local PSTN in the region of the called party, and uses the local PSTN to connect the call to the called party.

Patent CA-2241339-A1 (CA)
Inventor: POULIN RICHARD
IPC: C07C323/41
Filed: 1997-10-22
Abstract: The present invention describes the design, synthesis and therapeutic use of a variety of novel inhibitors of polyamine transport. The main feature of this class of transport inhibitors is to incorporate a linker or side chain that prevents the uptake of polyamines and helps to conjugate polyamine analogs to form dimers with high inhibitory potency against polyamine uptake. These new compounds incorporate features that are designed to maximize their chemical and metabolic stability and their ability to bind to the polyamine transporter, and to minimize their toxicity by preventing their absorption by the cells. The purpose of such inhibitors is to prevent the uptake or salvaging of circulating polyamines by rapidly proliferating cells such as tumor cells, in order to potentiate the effect of therapeutic inhibitors of polyamine biosynthesis such as Eflornithine.

Patent CA-2246152-A1 (CA)
Inventor: RENSHAW ANTHONY A
IPC: G11B19/26
Filed: 1998-08-27
Abstract: A stress induction method can be used to increase the operational speed range of rotating disks such as industrial circular saws and computer disk drives. In this method, stresses are generated in the disk by producing displacements or tractions at the inner radius of the disk. The magnitude of the displacements or tractions depends on the rotation speed. For example, by allowing concentrated masses to rest along the inner radius of the disk in-plane stresses proportional to the square of the rotation speed are generated. This technique can double the maximum speed for hydrodynamically uncoupled disks and can increase the maximum speed of disks with substantial hydrodynamic coupling by an order of magnitude.

Patent CA-2257702-A1 (CA)
Inventor: HALLETT RICHARD A
IPC: F04D13/16
Filed: 1998-12-31
Abstract: A floor mounted sump pump assembly for pumping particulate laden dirty coolant discharged by a floor mounted machine tool station includes a sump tank having a cylindrical wall spaced around a central axis and an inclined bottom with a central lower region. A pump is positioned within the sump tank offset from the central axis. The pump has an inlet oriented above and adjacent to the central lower region. A conduit has an outlet coupled to the sump tank for discharging dirty coolant from the machine tool station into the sump tank. The discharged dirty coolant swirls down around the inclined bottom to the central lower region for the pump inlet to pump the dirty coolant out of the sump tank. An overflow tank is adjacent to the sump tank to collect overflow coolant from the sump tank. A return pump is operable with the overflow tank to discharge the overflow coolant back into the sump tank. The sump tank is sized sufficiently small to maintain a sufficient coolant swirl velocity to prevent particulate from settling out.
Patent CA-2258680-A1 (CA)
Title: Desiccant entrained polymer
Inventor: HEKAL IHAB M
IPC: B29C45/16
Filed: 1998-03-05
Abstract: The present invention includes processes and resulting structures for producing moisture absorbing desiccant entrained polymers. A polymer is caused to assume a molten state, typically by applying heat and melting the polymer. To achieve certain results in the hardened end product, such as rigidity and durability, the polymer normally acts as a moisture barrier in a solidified state, both before and after melting. A  desiccating agent is blended into the polymer so that the desiccating agent is distributed within the polymer. A channeling agent is also blended into the polymer so that it is distributed within the polymer. The blending of the components is preferably done before the polymer is caused to assume a molten state. Together, the polymer, desiccating agent and channeling agent create a blended mixture. The mixture is solidified so that the channeling agent forms passages in the mixture through which moisture is communicable to desiccating agent that is entrained within the mixture. The solidified mixture may be used to form plug type inserts and liners for closed containers, or it may be used for producing laminated sheeting employed as package wrap.
