Patent CA-2110903-A1 (CA)
Title: Transdermal drug delivery system
Inventor: D ANGELO JOSEPH
IPC: A61M37/00
Filed: 1993-03-26
Abstract: A multidose transdermal drug delivery assembly comprises a laminate composite having a plurality of reservoirs (7) formed therein.  Unit doses with transdermal drug actives for transdermal administration are disposed in the reservoirs. Individual seals (5) enclose the drug in each of the reservoirs. The unit doses are in the form of a multiphase composition of microspheres wherein an internal phase comprises the drug actives and adjuvants surrounded by an outer phase of film-forming polysaccharides engrafted with transdermal promoters. The microspheres are distributed through a diffusable matrix for the composition. The individual seals (5), upon activation, disrupt the microspheres (8) to release the drug actives and adjuvants in the unit dose compartment (7), and the drug diffuses through the matrix to a patient's skin. A security strip (14) may be provided to prevent accidental activation of the drug.

Title: Flow coat galvanizing
Inventor: UNGER CARL H
IPC: C23C2/00
Filed: 1992-06-23
Abstract: This continuous galvanizing method and apparatus passes a linear element to be galvanized, e.g., wire, rod, or tube, through a surrounding, relatively short length of conduit which is attached as a cross-tee to the end of a delivery pipe rising from a centrifugal pump submerged in a vat of molten zinc, and continuously flooded with liquid zinc to coat the linear element. The zinc flowing from the open ends of the conduit, and falling as excess from the element being coated, drops back into the vat for recirculation. The vat is covered to provide a substantially closed operating space above the pool of molten zinc to enable the coating to take place in an inert atmosphere.

Title: Method for reducing volume of a radioactive composition
Inventor: NAGEL CHRISTOPHER J
IPC: G21F9/30
Filed: 1992-11-06
Abstract: 2121813 9309543 PCTABS00022 A method is disclosed for reducing the volume of a radioactive composition by separating a radioactive first component from a second component of the radioactive composition. The method includes directing the radioactive composition into a reaction zone. The reaction zone includes a molten bath, wherein oxidation of a component of the radioactive composition in the molten bath will cause separation of the radioactive first component from the second component. An oxidizing agent is directed into the molten bath, which oxidizes a component of the radioactive composition, whereby the radioactive first component is separated from the second component. The net volume of the radioactive composition is thereby reduced.

Title: DS/CDMA Receiver for High-Speed Fading Environment
Inventor: USHIROKAWA AKIHISA
IPC: H04B1/7097
Filed: 1994-07-08
Abstract: A receiver is disclosed for a DS/CDMA communication system wherein a symbol is spread with a predetermined spread code to produce a DS/CDMA signal which is transmitted on a radio frequency carrier. The receiver includes an interference canceller for cancelling signals from undesired sources introduced to a signal received from a desired source using a feedback signal. A phase variation canceller is provided for cancelling a phase variation that occurs in an interval between successive symbols of the received signal. Both cancellers are connected in series. A decision circuit compares an input signal from the interference canceller or from the phase variation canceller with a threshold and produces an output representing one of two discrete values depending on whether it is higher or lower than the threshold. A correction circuit derives a correction signal from a signal produced by the interference canceller and applies it to the interference canceller as the feedback signal.

Patent CA-2154404-A1 (CA)
Title: Prevention of parameter excursions in gas turbines
Inventor: MIRSKY SAUL
IPC: F04D27/02
Filed: 1995-07-21
Abstract: An improved method is provided for controlling fuel flow to the combustor of a gas generator turbine during sudden changes in load or during a surge cycle of the process turbocompressor. Surge control is intiated by analog input signals emanating from various devices located throughout the compressor-process system. The fuel control system includes input signals from the gas turbine driver. These signals are acted upon by the fuel control system which transmits a signal to a fuel valve actuator that controls the valve that meters fuel to the combustor. In addition to this sequence of control communication, however, is a rate-of-change in the amount of the fuel provided. The rate of the increase of the amount of fuel is determined by current operating functions of the fuel control system. However, because of the characteristics ofgeneral load rejection and recovery, and the abrupt nature of surge, the rate ofchange in the flow rate of fuel is extremely high. This rapid increase of fuel to the combustor may lead to dangerous excursions in temperature,  resulting in high temperatures in gas turbine elements. Consequently, a new function is added to the fuel control system's operation whereby improved regulation of the rate of increase of fuel is achieved. This new function receives a signal that either surge or a change in load has been detected. Next, a signal is transmitted to the fuel valve actuator, regulating fuel to the combustor, thus power to the power turbine, thereby preventing overspeeding. After that, the rate of change of the fuel valve is limited for a period of time. Once recovery has been accomplished, the change rate of the fuel valve is gradually returned to a normal operating setting.

Title: Diffusion barrier layers
Inventor: DEAKIN MARTIN JOHN
IPC: C23C14/16
Filed: 1994-02-15
Abstract: A method of applying a continuous stable intermetallic diffusion barrier layer to a high temperature metallic article is described. In many instances, protective coatings are incompatible with the material of the substrate to which they are applied. Such incompatilibility is overcome in the invention through in situ formation of an intermediate stable diffusion barrier layer by sequential deposition and subsequent reaction of suitable metals to form a continuous intermetallic layer. A  conventional overlay coating may then be applied to the intermetallic layer without risk to the underlying substrate. The invention also contemplates creation of unitary diffusion barriers from multi-layer deposits; deposition of plural diffusion barriers, and formation of complete protective systems comprising substrate, diffusion barrier(s) and overlay coating prior to heat treatment in situ.
