Patent CA-2557582-A1 (CA)
Title: Methods, compositions, and apparatuses for forming macrocyclic compounds
Inventor: JOHNSON THOMAS E
IPC: C07D491/08
Filed: 2005-02-17
Abstract: This invention relates to methods, compositions, and apparatuses for producing macrocyclic compounds. First, one or more reactants are provided in a reaction medium, which are capable of forming the macrocyclic compound through a desired reaction pathway that includes at least cyclization, and which are further capable of forming undesired oligomers through a undesired reaction pathway that includes undesirable oligomerization. Oligomerization of such reactions in the reaction medium is modulated to reduce formation of undesired oligomers and/or to reduce separation of the undesired oligomers from the reaction medium, relative to a corresponding unmodulated oligomerization reaction, thereby maximizing yields of the macrocyclic compound. The macrocyclic compound so formed is then recovered from the reaction medium.  Preferably, the macrocyclic compound spontaneously separates from the reaction medium via phase separation. More preferably, the macrocyclic compound spontaneous precipitates from the reaction medium and therefore can be easily recovered by simple filtration.

Title: Video processing with multiple graphics processing units
Inventor: DIARD FRANK R
IPC: H04N5/91
Filed: 2006-11-03
Abstract: One embodiment of a video processor includes a first media processing device coupled to a first memory and a second media processing device coupled to a second memory. The second media processing device is coupled to the first media processing device via a scalable bus. A software driver configures the media processing devices to provide video processing functionality. The scalable bus carries video data processed by the second media processing device to the first media processing device where the data is combined with video data processed by the first media processing device to produce a processed video frame. The first media processing device transmits the combined video data to a display device. Each media processing device is configured to process separate portions of the video data, thereby enabling the video processor to process video data more quickly than a single-GPU video processor.

Inventor: FORSTER IAN J
IPC: G01M99/00
Filed: 2005-06-29
Abstract: An RFID device preparation system includes a printer combined with a short-range tester/reader. The tester/reader operatively couples to the RFID device using capacitive and/or magnetic coupling. By use of capacitive and/or magnetic coupling, good read characteristics may be obtained, while obtaining excellent discrimination between various RFID devices that may be in or near the tester/reader. Thus, RFID devices may be inexpensively and reliably tested one at a time, without appreciable interference or effect due to the presence of other RFID devices. The tester/reader may include electric-filed and/or magnetic-field coupling elements that are configured to receive different signals, in order to test a variety of configurations of RFID devices. This may enable the device preparation system to accommodate various types and configurations of RFID devices, increasing versatility of the system.

Title: Device for storing and dispensing cosmetic compositions
Inventor: KUREK JOHN S
IPC: B43K5/06
Filed: 2005-08-05
Abstract: A drive screw having an axial bore is disposed within a tubular container. A  cap for closing the container has mounted therefrom an applicator that is insertable in the bore of the drive screw. A first seal and a second seal, on the drive screw, form with the inner wall of the container and the outer wall of the drive screw an annular compartment for housing a cosmetic composition.  A normally closed channel is provided between the compartment and the bore of the drive screw. A drive on the cap and a complementary drive on the drive screw cooperate with the first seal and the second seal to decrease the volume of the compartment in which the composition is housed each time the container is opened by removing the cap. A valve opens the channel in response to the decrease in volume in the compartment when the cap is removed so as to permit composition to flow through the channel into the bore of the drive screw to contact the applicator.

Filed: 2005-08-30
Abstract: L'invention porte sur un procédé et un système de stabilisation destinés à stabiliser la consommation énergétique dans des chargements multiples, ou dans des chargements uniques à phases multiples. Le procédé et le système permettent également de compenser le déséquilibre dans des chargements à phases multiples. Une commande centrale contrôle la réactance variable dans les charges et identifie des situations de variation de puissance et/ou de courant et/ou de déséquilibre. Elle détermine la mesure de correction appropriée prise par les autres charges/phases pour compenser la variation de puissance et/ou de courant ou de déséquilibre causée par la charge critique, et émet des signaux de commande qui donnent la consigne à des commandes de réactance variable associées aux autres charges, de se régler en conséquence. Le procédé et le système peuvent être appliqués à des installations de fours électriques à arc. Dans ce contexte, le procédé et le système prévoient une commande de position d'électrode couplée à la commande de vitesse d'avance, de façon à anticiper par prédiction l'introduction d'un nouveau matériau source et d'enlever les électrodes de façon à empêcher le soufflage de l'arc pendant que les éléments à réactance variable maintiennent des points de réglage de puissance. La commande de position de l'électrode peut être utilisée à la place du système de commande de réactance variable pour prendre des mesures de correction des variations de puissance et/ou de courant ou des déséquilibres.
