Patent CA-2234585-C (CA)
Inventor: LAWTER JAMES RONALD
IPC: A61K39/39
Filed: 1996-10-10
Granted: 2007-05-01
Abstract: Formulations for controlled, prolonged release of GM-CSF have been developed.  These are based on solid microparticles formed of the combination of biodegradable, synthetic polymers such as poly(lactic acid) (PLA), poly(glycolic acid) (PGA), and copolymers thereof with excipients and drug loadings that yield zero order or first order release, or multiphasic release over a period of approximately three to twenty-one days, preferably one week, when administered by injection. In the preferred embodiment, the microparticles are microspheres having diameters in the range of 10 to 60 microns, formed of a blend of PLGA  having different molecular weights, most preferably 6,000, 30,000 and 41,000. Other embodiments have been developed to alter the release kinetics or the manner in which the drug is distributed in vivo. For example, in some cases a polymer is selected which elicits a mild inflammatory reaction, for example, PLGA and polyanhydrides can act as chemoattractant, either due to the polymer itself or minor contaminants in the polymer, or polymers which are bioadhesive are used for transmucosal or oral delivery. In another embodiment, the GM-CSF is administered in a hydrogel which can be injected subcutaneous or at a specific site for controlled release. The microparticles or hydrogel are administered to the patient in an amount effective to stimulate proliferation of hematopoietic cells, especially white cells.

Granted: 2003-04-08
Abstract: Two shingled streams of signatures are stacked independently of each other in separate stacking bins that are aligned vertically one above the other and also vertically aligned with the collection bin of a re-feeder.      The collection bin is replenished periodically by stopping the shingled streams and unloading the contents of the lower and upper stacking bins to form a combined stack of signatures in the re-feeder collection bin. Signatures in the re-feeder collection bin are delivered by an out-feed conveyor belt in a single reshingled stream of signatures to an in-line processing station. In an alternative embodiment, the stacking bins are laterally separated with respect to each other for separately stacking signatures from two incoming shingled streams that are being output from separate web presses or other independent sources.

Patent CA-2283859-C (CA)

IPC: H04J13/02
Filed: 1998-02-24
Granted: 2005-08-02
Abstract: A discret multitone stacked-carrier spread spectrum communication method is based on frequency domain spreading including multiplication of a baseband signal by a set of superimposed, or stacked, complex sinusoid carrier waves. In a preferred embodiment, the spreading involves energizing the bins of a large Fast Fourier transform (FFT). This provides a considerable savings in computational complexity for moderate output FFT sizes. Point-to-multipoint and multipoint-to-multipoint (nodeless) network topologies are possible. A code-nulling method is included for interference cancellation and enhanced signal separation by exploiting the spectral diversity of the various sources. The basic method may be extended to include multielement antenna array nulling methods for interference cancellation and enhanced signal separation using spatial separation. Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment. Such systems are compatible with bandwidth-on-demand and higher-order modulation formats and use advanced adaptation algorithms. In a specific embodiment the spectral and spatial components of the adaptive weights are calculated in a unified operation based on the mathematical analogy between the spectral and spatial descriptions of the airlink.

Title: Railway locomotive ecp train line control
Inventor: KULL ROBERT C
IPC: B60T17/18
Filed: 1999-11-23
Granted: 2003-03-11
Abstract: An interface adapter is provided between the locomotive MU cable and the ECP  trainline permitting ECP data from the lead locomotive to be transmitted via the MU  cable on trailing locomotives to a train of ECP cars. On the lead locomotive, the HEU  Echelon interface is on a suitable line in the MU cable instead of the separate ECP  tramline such that trailing locomotives do not require a separate ECP trainline. The adapter generally employs two transceivers configured as back-to-back repeaters to bridge ECP  data between the locomotive MU cable and the ECP trainline. A DC-DC converter can be used to provide the ECP trainline voltage, either as 230 VDC or as a lower voltage. In lower voltage systems the converter may be replaced by a voltage regulator, or may be eliminated. In any case, an inductor is employed on the output to provide a high impedance to the overlay transceiver.

Those calculated partial derivatives are rebinned to the first derivative of the Radon transform, for both the circular orbit data and the arc orbit data. The second partial derivative of the Radon transform is then calculate d and then the reconstructed 3-D images are obtained by backprojecting using the inverse Radon transform.

Title: Stable cosmetic compositions with different ph emulsions
Inventor: MUKHERJEE SURAJIT
IPC: C09K23/00
Filed: 1998-10-06
Granted: 2008-02-26
Abstract: The inventive compositions contain an oil-in-water and a water-in-oil emulsion, each buffered to a specific pH, so that the difference in pH values of the two emulsions is at least two units. The molecular mixing is minimized by selecting suitable oil and oil phase in a water-in-oil emulsion. The change in pH is further minimized by buffering each emulsion. The particular advantage of the inventive compositions is the ability to separate within a single composition, with minimal intermixing, active compounds which require different pH  environments for stability and/or optimum efficacy.
