Patent CA-2290180-A1 (CA)
Title: Rotary die laser machining and hardening apparatus and method
Inventor: PFAFF ALAN R JR
IPC: B23P15/40
Filed: 1999-11-23
Abstract: A pair of rotary die cylinders having co-acting cutting blades formed by integral lands projecting generally radially outwardly from the main body of each cylinder and a method of making them by rough machining a tool steel workpiece with conventional cutting tools to form the general contour and path of the cutting blades and thereafter final machining and simultaneously heat treating the cutting blades with a laser to provide an accurately formed and hardened cutting blade. Preferably, the rough machining with conventional cutting tools and the final machining and heat treating by a laser are performed with the same machine tool, such as a computerized numerical control (CNC) machining center. Such a machining center permits rapid and accurate rough machining as well as accurate final laser machining of the cutting blades. The more accurate final machining accomplished by a laser produces a more accurately formed cutting blade and also simultaneously heat treats the blade with minimal distortion of the blade and without any significant distortion of the core or body of the cylinder.

Filed: 1998-06-06
Abstract: The invention relates to biodegradable linear polyester urethanes and to biodegradable cross-linked polyester urethanes obtained from linear polyester urethanes by virtue of the fact that they are cross-linked by diisocyanate bridges. By varying the degree of crosslinking, the physical, chemical and biological properties of the inventive cross-linked polyester urethane can be adjusted and the biodegradability thereof can also be varied considering that biological degradability occurs more slowly as the degree of crosslinking increases. The invention also relates to a method for producing the inventive polyester urethanes and to the use thereof as films, rubber bodies, containers, packaging materials and in galenical preparations, as adhesives, adhesive strips and the like. The invention also relates to polymer blends containing the inventive polyurethanes.

Patent CA-2293424-A1 (CA)
Inventor: PERSSON MAGNUS STIG
IPC: H04B7/005
Filed: 1998-06-05
Abstract: Methods of controlling the power levels of transmitted signals in telecommunication systems are described. For example, a remote terminal measures the quality of a received signal, either by determining the frame error rate or the bit error rate, and reports its quality measurement to a network by sending a quality message. The network causes the signal transmitters to adjust their transmit power levels appropriately. Faster power control methods may be combined with slower power control methods for downlink (network to remote terminal) transmissions in various communications scenarios, such as soft hand-overs.

Abstract: The cardioprotective effects of estrogen are well recognized. In in vitro experiments, and upon systemic administration, 17 - beta estradiol has shown to inhibit vascular smooth muscle cell proliferation and intimal hyperplasia. We hypothesized that locally delivered 17 - beta estradiol could inhibit neointimal proliferation following balloon angioplasty in porcine coronary arteries. Immunohistochemical, and morphometric analyses revealed that, arterial segments treated with local delivery of 17 - beta estradiol showed significantly less smooth muscle cell proliferation and neointima formation. Compared to PTCA only, or vehicle alone, 17 - beta estradiol decreased neointima formation by 54.6 % and 64.9 % respectively.

Abstract: A method and apparatus for assembling idler rollers. A pipe is positioned on a pipe cradle. A first end cap is positioned on an extendible support pin of a first end cap support. A second end cap is positioned on a retractable support pin of a second end cap support. A shaft is extended through the pipe and supported between shaft support lips carried by the first end cap support and the second end cap support. A first drive is activated to press the first end cap and the second end cap into the ends of the pipe. A second drive is then activated to extend the extendible support pin to exert a force upon the shaft to axially move the shaft into a central passage of the second end cap. Such axial movement is accommodated by the retractable support pin until a stop position is reached.

Title: Private network access point router for interconnecting among internet route providers
Inventor: WHEELER CHRISTOPHER D
IPC: H04L12/56
Filed: 1998-09-02
Abstract: A P-NAP routing complex (100) for routing packet traffic on the Internet using core routers connected to National Internet Services providers such as MCI  (420), Sprint (422), and the like. Configuration files that instruct BGP4 Border Gateway Protocol version 4 to control the path of outgoing packets as well as the packet return path are created and loaded into the core routers as ASCII text files. The code routers read off the commands one-by-one and act upon the commands by taking the appropriate action. In creating the router configuration files, it is necessary to instruct BGP4 to place different preference values on routes determined to be within a provider to which the P-NAP (100) has a connection from all other routes. There are four alternative methods for creating commands which instruct BGP4 on how to determine which routes are within a provider and which are not. There is a choice either specifically permitting all routes known to be a part of a provider or denying all routes known not to be part of a provider and permitting everything else.
