Title: Systeme de fixation par difference de pression s'adaptant automatiquement
Inventor: LEVIN DANIEL
IPC: B25J15/06
Filed: 2000-08-20
Granted: 2008-05-06
Abstract: Dispositif de fixation par différence de pression s'adaptant automatiquement et comprenant une source de vide (51), un réservoir de vide (54) communiquant de façon fluide avec la source de vide; une surface de contact (56) et une pluralité de conduits (55), dont chacun possède une entrée (2) placée sur la surface de contact et une sortie (3) communiquant de façon fluide avec le réservoir de vide. Ce conduit comporte une pluralité d'ailettes (4, 5) montées sur la paroi interne dudit conduit en deux groupements se faisant pratiquement face. Chacune des ailettes des groupements, à l'exclusion de celle située en position la plus proche de l'entrée et de celle située en position la plus proche de la sortie du conduit, est placée sensiblement en face d'une pluralité de cavités dans lesquelles les groupements opposés d'ailettes sont disposés de façon asymétrique. Quand du liquide s'écoule à travers le conduit, ceci produit une pluralité de tourbillons (6, 7) à l'intérieur des cavités qui existent au moins temporairement pendant l'écoulement, ce qui crée un blocage aérodynamique permettant à un écoulement central, entre les tourbillons et les extrémités des ailettes supprimant l'écoulement de manière unidimensionnelle, de limiter le débit-masse et de maintenir une chute de pression importante à l'intérieur du conduit.
Patent CA-2388003-C (CA)

Granted: 2013-02-19
Abstract: A portion of the lysostaphin gene of Staphylococcus simulans has been cloned and overexpressed in the cytoplasm of E.coli to yield mature lysostaphin, in the absence of preprolysostaphin and prolysostaphin, under the transcriptional control of an IPTG-inducible promoter and a ribosome binding site. IPTG  induction of the transformed host cells produces intracellular, soluble, mature lysostaphin (27 kDa), in the complete absence of preprolysostaphin and prolysostaphin. The mature lysostaphin so formed does not require post-translational modification. The mature lysostaphin so formed can be used to treat and prevent staphylococcal infections.

Title: Limited-bandwidth electronic data communication system
Inventor: PIDDUCK PATRICK
IPC: H04L29/06
Filed: 2001-03-13
Granted: 2005-01-04
Abstract: A limited-bandwidth network electronic data communication system (100) includes an electronic data transmission system (200) and a network terminal (300) in communication with the electronic data transmission system over a communications network (112). The electronic data transmission system includes a data receiver, a data formatter (218) and a data transmitter.      The electronic data terminal includes a data receiver, a data reformatter and a data transmitter. Using the data transmitter an operator of the electronic data terminal transmits a request for transmission of an electronic message from the electronic data transmission system to the electronic data terminal. Upon receipt of the transmission request, the data formatter of the electronic data transmission system formats the electronic message in accordance with a default filtration parameter associated with the electronic data terminal, and assembles the electronic message as part of an electronic data package. Alternately, the retransmission request may include at least one data filtration parameter defining a desired alternate resolution for the electronic message, in which case the data formatter of the electronic data transmission system formats the electronic message in accordance with the specified filtration parameter.  When the formatting step is completed, the data transmitter of the electronic data transmission system transmits the electronic data package to the electronic data terminal. Upon receipt of the electronic data package, the data reformatter of the electronic data terminal extracts the electronic message from the data package for review by the operator of the electronic data terminal.

Abstract: A method and apparatus are provided for fabricating of continuous castings with fine and uniform microstructure, which can be used as feedstock for secondary processing routes, such as thixoforming, forging and machining or direct application in industry. An overheated liquid alloy is fed into a high shear device (for example, a twin-screw extruder) and sheared intensively to produce a sheared liquid alloy or a semisolid slurry, wherein the sheared liquid alloy is at a temperature close to its liquidus and the semisolid slurry is then transferred to a shaping device for production of continuous castings with fine and uniform microstructures through a solidification process. The shaping device is any device capable of forming continuous (i.e.  infinite length) products, such as a direct chill (DC) caster (2) (DC  rheocasting) for production of continuous billets, an extrusion die (8) (rheo-extrusion) for production of continuous bars or wires, or a twin-roll caster (twin-roll rheocasting) for producing of continuous strips. In all those cases, the cross-section of the continuous castings exhibits a microstructure in which a controlled volume fraction of fine and spherical primary particles are uniformly distributed in a fine structured matrix.

Title: Local oscillator leakage control in direct conversion processes
Inventor: PETERZELL PAUL E
IPC: G01N33/14
Filed: 2002-01-10
Granted: 2011-01-04
Abstract: A system and method for generating a local oscillator (LO) frequency in a zero intermediate frequency (IF) receiver or transmitter is presented. A signal is received from a voltage controlled oscillator (VCO). The signal has a VCO frequency. The VCO frequency is divided by a number N to produce a signal having a divided-down frequency. The signal having the VCO frequency is then mixed with the signal having the divided-down frequency to produce an output signal having an output frequency. Local oscillator leakage is reduced. Thus, the receiver or transmitter may operate in multiple wireless communication bands and modes and meet the associated specifications.

Abstract: L'invention concerne une batterie de piles à combustible dotée d'un générateur d'électricité comprenant une électrode à oxygène, une électrode à combustible et une pellicule électrolytique de type polymère solide pincée par l'électrode à oxygène et par l'électrode à combustible. L'invention concerne également un procédé permettant de commander une telle batterie de piles à combustible. Jusqu'à présent, l'inconvénient majeur des batteries de piles à combustible résidait dans la réduction de la sortie même de la batterie en raison du dessèchement du film électrolytique provoqué par la baisse des caractéristiques d'échange d'ions en cas de réduction du courant de charge pendant le fonctionnement, d'une augmentation de la quantité d'air fournie ou d'une inactivité de longue durée. La batterie de piles à combustible est pourvue d'une section de commande de charge ou d'un section de commande d'alimentation en air, afin de permettre la modification d'une charge de la batterie en fonction d'une condition de sortie. Lorsque les caractéristiques de sortie baissent ou qu'une valeur de résistance interne augmente, la batterie de piles à combustible décrite dans cette invention est commandée de manière à augmenter le courant de charge ou à supprimer l'alimentation en air.
