Title: Routing area updating in packet radio network
Inventor: KANGAS ISMO
IPC: H04L12/56
Filed: 1998-01-19
Abstract: The invention relates to a cellular packet radio network and to a method for updating a routing area in a packet radio network. Packet radio support nodes (SGSN) are connected to a digital cellular radio network (BSS), which provides a radio interface for the support nodes for packet-switched data transmission between the support nodes and mobile stations. There is a logical link between a mobile station (MS) and a serving packet radio support node (SGSN). The packet radio network utilizes logical routing areas, each of which comprises one or more cells. Each cell broadcasts information on the routing area to which it belongs. The mobile station sends a routing area update request to the packet radio network when it roams to a new cell which belongs to a different routing area than the old cell. The update request includes the identifiers of the old and new muting area. When the packet radio node detects a routing area update carried out by an unknown mobile station, it initiates the establishment of a logical link by sending a link establishment message (L,L.C Subm, 21, 21') to the mobile station, the message including the same identifier the mobile station used for itself in the routing area update request. The mobile station initializes the logical link at its own end and sends and acknowledgement to the serving packet radio support node.

Title: Strengthened fiber optic cable
Inventor: WAGMAN RICHARD S
IPC: G02B6/44
Filed: 1999-09-02
Abstract: A fiber optic cable having strength assemblies (30) adjacent a tube for imparting crush resistance to the cable, at least one of the strength assemblies including a strength member in contact with a tube having at least one optical fiber therein. The strength member is coupled to a first jacket, and may be surrounded a single jacket, or by an armor tape and a second jacket. The strength member may be disposed in a recess of the tube. When crush loads are applied to the fiber optic cable, the stresses created in the cable are advantageously distributed by strength assemblies (30) whereby stress concentrations and undue deflection of the cable in response to the crush loads are avoided. Tight coupling and minimized gaps between the cable components in strength assemblies (30) inhibits slippage and/or warping of the components under stress, and thereby evenly distribute the stress for preventing crush induced attenuation in the optical fibers. Figures 1 and 2.

Title: Implantable delivery device with self adjustable exit port
Inventor: GUMUCIO JUAN C
IPC: A61K9/22
Filed: 1998-03-10
Abstract: A delivery device having a first chamber containing an osmotic agent, 'a membrane forming a wall of the first chamber through which fluid is imbibed by osmosis, a second chamber containing a beneficial agent to be delivered, and a moveable piston separating the two chambers. In fluid communiation with the second chamber is an orifice which comprises a slit valve. In the presence of pressure, the beneficial agent pushes through the slit, opening up a channel for delivery of the beneficial agent and creating flow. Because the slit remains closed in the absence of flow (or when the pressure is below the pressure required to open the slit), back diffusion of external fluids is eliminated when the slit is closed, which prevents contamination of the beneficial agent in the second chamber by external fluids. In addition, forward diffusion of the beneficial agent out of the capsule is prevented when the slit is closed. The slit valve opens only to the minimum dimension required to allow the flow generated by the osmostic pumping rate. The slit valve also allows a flow path to open around any obstruction in the slit valve to prevent clogging.

Abstract: A self-adhesive label for a container, such as a pharmaceutical bottle, comprises three sections. The first and third sections adhere the label to the bottle. The second section is contiguous with the first section, and is attached to the third section by means of a perforation. This second section is the "peel-away" section and contains printed information on both its front and rear surfaces. The second section has a non-adhesive rear surface and contains a tab for ease of gripping. The second section may be torn along the perforation by use of the grip tab, to enable viewing of the information printed on the rear surface of the second section of the label. The second section can then swing free of the bottle, yet remains attached to the first section.      After reading the information contained on the rear surface of the second section, the consumer can than reseal this portion of the label to its original position on the bottle. This is possible due to the presence of relatively minute spots of adhesive on the rear surface of the second label section which will reseal the label to the bottle until such a time as the consumer wishes to reopen the label.

Filed: 2000-04-07
Abstract: A mig welding gun handle is in two sections that are offset from each other by an angle of approximately 20 degrees.      The offset handle makes the gun exceptionally comfortable for an operator to maneuver when welding various workpieces. A non-right angle gear set in which the pinion axial centerline intersects the gear axis of rotation at an angle of approximately 70 degrees makes the offset handle possible. The gun further comprises a gas seal that blocks atmospheric air in the weld wire liner from reaching the welding arc. The gas seal comprises a passage that bleeds inert gas to the interior of the liner. The relatively high pressure of the inert gas in the liner interior blocks atmospheric air from flowing through the hole in the contact tip to the arc.
