Patent CA-2279667-A1 (CA)
Title: A mobile point-to-point protocol
Inventor: RAI GIRISH
IPC: H04L12/56
Filed: 1999-08-05
Abstract: Apparatus for transferring packet data incorporates a "hand-off" feature that allows the transfer of an existing PPP connection from one packet server to another packet server. Such a hand-off control message or call continue transaction can be initiated by any of the servers involved in the transactions. For instance, assume an initial arrangement where a point-to-point call is set up and in progress between a user and a private network via a first packet server (e.g., a first Serving LAC) and a second packet server (e.g., an Anchor LAC). If, for example, the user moves out of the region served by the first packet server into a region served by a third packet server (e.g., a second Serving LAC), then a hand-off control message transaction, according to the invention, is initiated. Either the second Serving LAC or the Anchor LAC may initiate the call continue transaction. Alternatively, radius servers respectively associated with the packet servers may be employed to perform the call continue transaction. Furthermore, assuming that a communication path is not yet established between the second packet server (e.g., Anchor LAC) and the third packet server (e.g., the second Serving LAC), a communication path (e.g., tunnel) set-up control message transaction may be performed concurrent with the call continue transaction. Still further, at least one packet server (e.g., the Anchor LAC) monitors state variables associated with the packet servers (e.g., the second Serving LAC and the private network) from which it receives packet data.

Title: Drain valve assembly and method of cleansing
Inventor: JACUZZI REMO C
IPC: A61H33/00
Filed: 1999-12-23
Abstract: A drain valve assembly for use with an air bath including an air distribution system and a method of cleansing channels of an air distribution system for a bath vessel.  The drain valve assembly is located within an opening in the bath vessel to control the flow of water from the bath vessel to an effluent drain, to control the flow of air and water from the air distribution system to an effluent drain and to maintain a fluid pressure within the air distribution system. The drain valve assembly includes a valve housing for extending between the bath vessel and a fluid waste pipe connected to the effluent drain. The valve housing has an upper opening for positioning proximate the bath vessel and a lower opening for receiving fluid from the air bath distribution system. The drain valve assembly also includes a stopper having first and second vertically aligned plungers. The stopper is secured within the valve housing and is capable of moving relative thereto. When the stopper is in a closed position and the second plunger is positioned below a lower surface of the lower opening, fluid from the air distribution system is sealed within the valve housing and fluid within the bath vessel is prevented from entering the valve housing.  Conversely, fluid from the bath vessel and the air distribution system flows through the valve housing and into the fluid waste pipe when the stopper is in an open position and the second plunger is above a lower surface of the lower opening.

IPC: B01J20/30
Filed: 1999-12-29
Abstract: A process for the preparation of high surface area, low-swelling macroporous polymeric adsorbents is disclosed.

Patent CA-2303432-A1 (CA)
Title: Modulation of drug loading in multivesicular liposomes
Inventor: SANKARAM MANTRIPRAGADA
IPC: A61P9/12
Filed: 1998-09-08
Abstract: Disclosed is a method for making liposomes, for example multivesicular liposomes (MVLs), containing one or more biologically active agents, wherein the loading of the active agents into the liposomes is modulated by adjusting the osmolarity of the aqueous component into which the agents are dissolved prior to encapsulation. To increase the loading of the active agent, the osmolarity of the aqueous component is reduced, and to decrease the loading of the active agent, the osmolarity of the aqueous component is increased. In the making of MVLs, the process involves dissolving the active agent and an optimal osmotic excipient in a first aqueous component encapsulated within the liposomes. For any given concentration of drug, the osmolarity of the first aqueous component can be adjusted by increasing or decreasing the concentration or molecular weight of the osmotic excipients used therein.  The rate of release of the active agent into the surrounding environment in which the liposomes are introduced can be simultaneously controlled by incorporating into the lipid component used in the formulation at least one long chain amphipathic lipid. For example the amphipathic lipid can have from about 13 to about 28 carbons for example, from about 18 to about 22 carbons, in its carbon chain. Use of the long chain amphipathic lipid in the lipid component is particularly helpful in controlling the release rate and encapsulation efficiency for high drug load formulations.

Patent CA-2308277-A1 (CA)
Inventor: LI XIANFENG
IPC: C07K14/805
Filed: 1998-11-03
Abstract: Hemoglobin cross-linked with disulfide linkages at sites external to the native globin chains is prepared by reacting hemoglobin with site-directed reagents exemplified by N,N'-bis Cbz-cysteinyl bis (methyl phosphate). Reaction with deoxy hemoglobin produces two main products: cross-linked hemoglobin as the bis cysteinyl amide of the .epsilon.-amino group of the side chain of Lys-82 of the two .beta. subunits, and modified but non-cross-linked hemoglobin that has each of the same amino groups modified as the cysteinyl amide. Disulfide cross-linked hemoglobin has a variety of uses. The disulfide bonds can be cleaved with reducing agents to give terminal sulfhydryl groups, useful in chemical bonding to sulfhydryl group-containing biochemically active compounds to form conjugates thereof for drug delivery. Hemoglobin crosslinked through disulfide bonds can be formed from the sulfhydryl group terminated reduction products, for use as a hemoglobin-based oxygen carrier.
