Patent CA-2202300-A1 (CA)
Title: Active agent transport systems
Inventor: SARUBBI DONALD J
IPC: A61K9/16
Filed: 1995-10-24
Abstract: Methods for transporting a biologically active agent across a cellular membrane or a lipid bilayer. A first method includes the steps of: a) providing a biologically active agent which can exist in a native conformational state, a denatured conformational state, and an intermediate conformational state which is reversible to the native state and which is conformationally between the native and denatured states; b) exposing the biologically active agent to a complexing perturbant to reversibly transform the biologically active agent to the intermediate state and to forth a transportable supramolecular complex; and c) exposing the membrane or bilayer to the supramolecular complex, to transport the biologically active agent across the membrane or bilayer. The perturbant has a molecular weight between about 150 and about 600 daltons, and contains at least one hydrophilic moiety and at least one hydrophobic moiety. The supramolecular complex comprises the perturbant non-covalently bound or completed with the biologically active agent. In the present invention, the biologically active agent does not form a microsphere after interacting with the perturbant. A method for preparing an orally administrable biologically active agent comprising steps (a) and (b) above is also provided as are oral delivery compositions. Additionally, mimetics and methods for preparing mimetics are contemplated.

Patent CA-2209316-A1 (CA)
Title: Fluidized bed assembly with flow equalization
Inventor: HYPP NEN TIMO
IPC: B01J8/26
Filed: 1996-01-04
Abstract: A fluidized bed assembly, such as an ash cooler, includes first and second fluidized bed chambers each having a bottom portion and side walls. Fluidizing gas is introduced into the bottom portions to fluidize particulates within the chambers. A flow equalizer (such as a barrier having a number of openings associated with it) separates the chambers and provides a substantial uniform flow of particulates from the first chamber to the second chamber so that no dead spots or corners form in the chambers adjacent the flow equalizer. Heat exchanger components are typically provided in the barrier for circulating heat exchange fluid through the barrier. Also, heat exchangers are provided in one or both of the chambers to cool the particulates. The particulates mix in the second chamber, and after cooling may be recirculated to a gasifier/combustor for supplying ash to the first chamber. A classifier chamber is connected between the reactor and the first chamber. Fluidizing gas may be returned from the chambers to the reactor.

Title: Coexisting communication systems
Inventor: DIXON ROBERT C
IPC: H04J3/06
Filed: 1996-10-07
Abstract: An integrated communication system supporting multiple TDMA or TDD  communication protocols, and includes means for selectively communicating according to either protocol. Each protocol defines time frames and/or time slots of a different duration (901, 911), from which is derived a composite time frame (925) having a predefined timing structure. A first base station unit (104) communicates in a first set of time slots of the composite time frame according to a first TDMA or TDD protocol, and a second base station unit (104) (which may be collocated with the first base station unit) communicates in a second set of time slots of the composite time frame according to a second TDMA or TDD protocol. Coordinating electronics (such as a GPS receiver in one or both base station units) are provided so as to prevent collisions between communications occurring between each base station unit and its respective users. In a particular embodiment, a first protocol is GSM protocol, and a second protocol is a TDD protocol utilizing spread spectrum techniques. The TDD protocol is structured so that each time slot is twice the duration of a GSM time slot, and each time frame is four times the duration of a GSM time frame. The system may comprise a number of "stacked"  base stations in a single cell, each operating over a different frequency or using different spreading codes.

Title: Preparation of aqueous solutions of free hydroxylamine
Inventor: SCHNEIDER HANS-MICHAEL
IPC: B01D1/28
Filed: 1996-12-20
Abstract: A process is disclosed for producing an aqueous solution of free hydroxylamine. A solution obtained by treating an hydroxylammonium salt with a base is treated with water or water vapour at a temperature ? 80 C, so as to separate the solution into an aqueous hydroxylamine fraction and a salt fraction. This process is soft and easy to implement on a Large scale. The risk of decomposition is minimised because of the low thermal stresses, the low hydroxylamine concentration and the short dwelling time during implementation of the process.
