Patent CA-2231977-A1 (CA)
Inventor: TERAYAMA HIDEO
IPC: A61K31/56
Filed: 1998-03-12
Abstract: The conventional aqueous suspension of loteprednol etabonate is not easily amenable to production pH control and entails a pH depression on long-term storage, thus irritating the eye or the nasal mucosa on instillation. When a C2-7 aliphatic amino acid is added to an aqueous suspension of loteprednol etabonate for topical ophthalmic use, the suspension does not undergo pH depression even on prolonged storage, with the result that no irritable response is elicited in the eye or nasal mucosa.

Patent CA-2248081-A1 (CA)
Title: Chromatic dispersion compensating node
Inventor: ELLIS ANDREW DAVID
IPC: H04B10/2519
Filed: 1997-03-05
Abstract: In the present invention, wavelength division multiplexed transmission line functions of chromatic dispersion compensation and channel drop are performed by a node having a concatenated series of wavelength selective dispersion compensating elements (F1-F3) and switches (S1-S4). The switches (S1-S4) are arranged to select or bypass each wavelength selective dispersion compensating element (F1-F3). If a wavelength selective dispersion compensating element (F1-F3) is appropriately selected, the corresponding channel (1-3) is dispersion compensated and reflected to a drop port (3). Any remaining channels are circulated by the switches (S1-S4) to the remaining dispersion compensating elements (F1-F3) where they are dispersion compensated and reflected to an optical output (5). In the preferred examples, the node includes an insert port (6) to allow multiplexing of additional channels. This allows the node to perform both drop and insert functions in addition to dispersion compensation and so forms a dispersion compensating drop and insert node.

Title: Optical multi-channel separating filter with electrically adjustable photon crystals
Inventor: KOOPS HANS WILFRIED PETER
IPC: G02F1/29
Filed: 1997-03-03
Abstract: The invention relates to the construction of optical multipath switches based on electrically switchable photonic crystals. A filled photonic crystal, switchable electrically and/or by light, is used as a tunable mirror.  By creating selective optical deformations in the photonic crystal, its properties can be influenced in selected areas in terms of transmission capability. This is done preferably by application of a strong electrical field.      Light is coupled in and out via fixed photonic mirrors located at an angle to the photonic crystal. The optical switches of the invention find application in switching networks and serve the purpose of service selection. A very high packing density may be achieved.

Title: Apparatus and method used in multiple, simultaneous synthesis of general compounds
Inventor: HORMANN ROBERT EUGENE
IPC: C40B40/06
Filed: 1998-11-02
Abstract: The apparatus and method of the present invention provides for conducting simultaneous multiple synthesis of general compounds, which often takes place under varied uneven conditions requiring heating, cooling, agitation, reagent/solvent additions to the reactor contents at each reaction vessel location, supply and maintenance of inert atmosphere and means to facilitate the reflux ofthe reactor contents. Thus, it becomes necessary to monitor and control the reaction conditions during the simultaneous multiple synthesis of general compounds. The apparatus allows the user to connect various independently controlling and conveying means to each reaction vessel through multiple ports provided on a stopper mounted on each reaction vessel. The apparatus of the present invention permits user to readily access the reaction vessels without interrupting the reactions occurring in the adjacent reaction vessels. The unique geometry and shape of the stopper allows positioning of multiple ports, while still providing the stopper with a compact size. As a result, a large array of reaction vessels can be accommodated in the device of the present invention without significantly increasing the overall size of the apparatus. Some of the general compounds that can be readily synthesized by the apparatus and the method of the present invention include inorganic compounds as well as organic compounds, such as oligomers, polymers, agricultural chemicals, drugs, peptides and oligonucleotides.

Patent CA-2254428-A1 (CA)
Inventor: BARNES KENYON
IPC: B28D1/04
Filed: 1998-11-24
Abstract: A masonry reinforcement system includes a number of tensioning rods extending from the top to the bottom of a masonry wall structure in spaced columns. In each column, several rod segments are interconnected at each floor diaphragm using a double conical connector assembly. In portions of the wall structure where rod columns cannot be placed, such as window regions, spring tensioning assemblies are installed using a similar double conical connector assembly. Each type of connector assembly is embedded in a pocket formed in the masonry wall structure using a hardenable grout. After installation, the rods are post-tensioned to provide a compressive axial load to the masonry wall structure. The spring tensioner assemblies are tensioned prior to applying the grout to the void in the wall. For deteriorated masonry walls, reinforcing members are installed in bore holes formed in the mortar using a hard epoxy bonding agent and a finishing mortar layer so that the reinforcing members blend into the appearance of the masonry wall structure.

Title: Purification of biologically active peptides from milk
Inventor: HAYES MICHAEL L
IPC: C12N15/09
Filed: 1997-05-13
Abstract: A method of separating a soluble milk component from milk (e.g., in a closed-loop continuous extraction system) is disclosed. The method involves the use of tangential flow filtration across a membrane to form a retentate and a permeate, subjecting the permeate to a capture device to substantially remove the soluble milk component, combining the effluent from the capture device with the original milk sample (retentate), and continuing this procedure until the milk has been sufficiently purified. Preferably, the milk is combined with a chelating agent, such as EDTA, to improve the purification efficiency. This procedure is advantageously employed with milk from transgenic animals which have been genetically altered to express exogenous proteins, such as therapeutic proteins, in their milk.

Inventor: WARD ANTHONY J I
IPC: C05G5/23
Filed: 1997-08-14
Abstract: A novel method is provided wherein plants are first treated with an exogenous chemical (e.g., glyphosate herbicide) and then sequentially treated with a liquid accession agent which provides improved biological (e.g., herbicidal) effectiveness such that plants are controlled with lower rates of the applied exogenous chemical (e.g., glyphosate herbicide). Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that can be exhibited when the accession agent is added to a herbicide in a tank mix or simple coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain organosilicone-based and fluorocarbon-based surfactants.
