IPC: A61K47/48
Filed: 1997-10-24
Abstract: An aqueous local anesthetic solution having a pH of 6.5-8.5, which contains a local anesthetic included in cyclodextrin or a derivatives thereof in a concentration of the local anesthetic of not less than 0.02%, a method for improving solubility of local anesthetic in water at a pH of 6.5-8.5, comprising including the local anesthetic in cyclodextrin or a derivative thereof, a local anesthetic agent comprising an inclusion compound of local anesthetic in cyclodextrin or a derivative thereof, a method for decreasing neurotoxicity of local anesthetic agent, comprising including the local anesthetic in cyclodextrin or a derivative thereof, and an inclusion compound of local anesthetic in cyclodextrin or a derivative thereof. The local anesthetic agent and aqueous local anesthetic solution of the present invention have decreased neurotoxicity, so that the duration of anesthesia can be controlled clinically safely by reducing/increasing its concentration or dose. In particular, the aqueous local anesthetic solution can be used at a pH near that of a living body. Thus, it can be used even when living tissue has an acidic pH. Moreover, the pain caused by local acidosis at an injection site by a conventional local anesthetic dissolved in an acidic solution can be reduced.

IPC: H04M7/12
Filed: 1997-11-05
Abstract: A system that dynamically creates a mailbox if the mailbox does not exist for a message at the time that the message is to be stored when dynamic mailbox creation is enabled. A system level process indicates that the mailbox exists and provides default subscriber information to a voice messaging application during the receipt of a message when a mailbox does not exist on the system for the recipient of the message and dynamic mailbox creation is enabled. At the time the message is to be stored the mailbox is created with the default subscriber information. The system checks for erroneous mailboxes by requesting confirmation of the recipient telephone number from the telephone system using a message waiting indication packet. This check can be performed before the mailbox is created when the mailbox address is available, while the message is being held before being stored, or it can be used to delete the mailbox after it is created. When the message is retrieved, the mailbox is initialized. Mailboxes that are not initialized and that are dynamically created are deleted after a mailbox expiration time period has elapsed.
Patent CA-2222276-A1 (CA)
Inventor: KIRCHGESSNER MICHAEL
IPC: B65D41/48
Filed: 1996-06-04
Abstract: A closure cap for closing containers has a closure floor (2), a jacket (3) and a tear-off ring (7). The latter is attached to the jacket (3) at connection points (8). To open the closure cap, force is exerted on the tear-off ring (7), thereby destroying two vertical tear lines (9) situated next to the connection points (8). This allows a region of the jacket (3) to bend outwards and makes opening the closure cap easier.

Abstract: Apparatus for measuring very low levels of polarization mode dispersion of optical devices, that is inexpensive, robust and portable, comprises a broadband source and a polarizes for directing substantially completely polarized broadband light into the device under test with the polarization in a plane substantially perpendicular to the propagation direction of the light. Light leaving the device is analyzed spectrally to produce a spectrum of intensity in dependence upon wavelength or frequency of such light for each of at least two mutually orthogonal polarization axes in a plane perpendicular to the propagation axis of the light leaving the device. The spectra are used to compute Stokes parameters s 1, s 2 and ~ s 3 ~ for each of a plurality of wavelengths within the bandwidth of the broadband light. The polarization mode dispersion of the device is characterized in dependence upon the Stokes parameters using one of several techniques including standard Fixed Analyzer techniques and polarimetric techniques, especially the Poincaré sphere technique. The apparatus is particularly suitable for measuring PMD of components of optical telecommunications systems, including optical fibers, optical isolators, couplers, light amplifiers, and dispersion compensators.

Patent CA-2242050-A1 (CA)
Title: Composite honeycomb sandwich structure
Inventor: ERICKSON DAVE G
IPC: B32B7/12
Filed: 1997-01-06
Abstract: We eliminate resin flow into the cells of honeycomb in sandwich structure by using an unsupported film adhesive (108), a barrier layer (110), and a scrim supported adhesive layer (112) between the composite laminate (102) and the core (106). We produce superior panels with lighter weights, improved mechanical properties, and more predictable structural performance by keeping resin in the laminate rather than losing it to the core cells. We reduce core crush and ply wrinkling in composite honeycomb sandwich structure by preventing slipping of tiedown plies relative to the mandrel and to one another during autoclave curing. We produce superior panels with lighter weights, improved mechanical properties, and more predictable structural performance. The method involves applying a film adhesive to the tiedown plies in the margin of the part outside the net trim line. During heating of the autoclave and prior to the application of high pressure to the composite structure, the film adhesive cures to form a strong bond between the plies and to the mandrel. When pressure is applied, the tiedown plies are locked together and to the mandrel to prevent slippage between any layers in the panel.
