Patent CA-2526197-A1 (CA)
Inventor: GULCICEK EROL
IPC: H01J49/42
Filed: 1995-02-27
Abstract: Un guide d'ions multipolaire qui commence dans une étape de pompage et s'étend en continu dans une ou plusieurs étapes ultérieures de pompage a été incorporé dans un système de spectromètre de masse à source d'ionisation à la pression atmosphérique. Les ions livrés dans le vide à partir d'une source à ionisation chimique à la pression atmosphérique ou une source d'ions plasmatiques à couplage inductif d'électronébulisation sont guidés et focalisés sur un analyseur de masse avec une grande efficacité en utilisant le guide d'ions multipolaire. La pression de fond sur une partie de la longueur du guide d'ions multipolaire est suffisamment élevée pour provoquer le refroidissement de l'énergie cinétique des ions traversant la longueur du guide d'ions en raison de collisions d'ions avec les molécules de gaz de fond neutres. Ce refroidissement de l'énergie cinétique d'ions réduit la propagation de l'énergie des ions traversant la longueur du guide d'ions multipolaire. Le potentiel de décalage en courant continu du guide d'ions multipolaire peut être utilisé pour ajuster l'énergie moyenne des ions et les valeurs a et q du guide d'ions peuvent être définies pour réduire ou étendre la gamme de masse des ions à être chargés qui seront transmis au travers du guide d'ions multipolaire. Ces caractéristiques de guides d'ions multipolaires et de plusieurs guides d'ions multipolaires d'étape de pompage sont utilisées pour améliorer les performances et réduire le coût des instruments de spectrométrie de masse à source d'ionisation à la pression atmosphérique.

Title: System and method for redirecting communications for a mobile device
Inventor: LAZARIDIS MIHAL
IPC: H04M3/54
Filed: 2005-12-20
Abstract: A method and system for automatically triggering call redirecting in response to a mobile device detecting its connection to a host such as a personal computer, is provided. In one embodiment, the mobile device detects connection by sensing application of a charging voltage via a Universal Serial Bus (USB) connection, and signaling the mobile device processor of the event. In response, the mobile device processor automatically decides to which alternative endpoint communications should be forwarded, and either instructs its transmitter to transmit a forwarding command to a network operations centre or instructs the host to transmit the command through the Internet. The network operations centre switch is operable to receive a call redirecting command respecting the mobile device from either the mobile device or the host to which the mobile device is connected, and adjusting its settings to effect call redirecting for subsequent communications for the mobile device.

Inventor: GANCARCIK EDWARD PETER
IPC: H04L12/413
Filed: 2006-05-02
Abstract: A midspan power adapter is provided for use in a balanced communication system, such as an Ethernet system, where differential signals are transmitt ed between two devices. The adapter passes data signals through, and provides power to an end device, such as an IP phone, with significantly less contribution to the electromagnetic emissions of the system than known midspan adapters. Balance and symmetry inherent in a structured cable can be maintained by a termination network connecting center taps of a transformer and the spare pairs of both the incoming and outgoing cable s to a common point. The adapter can provide power through unused wires (known as spare pair power) or by combining power with data signals (known as phantom feed). A common mode choke is included in the power feed to prevent noise currents fr om flowing through the power supply connections to earth ground, helping to minimize radiated noise.

Abstract: The invention can be defined in its most general form as a device for sheet material corrugation by means of bending and can be applied in the devices for production of single curvature folded core used in production of aircraft and craft curvilinear panelsThe invention has for its object to broaden the technological capabilities. For that the mandrel is made in the form of a set of alternating rows of plane elements (4, 6, 7) made in the form of trapeziums (4) and isosceles triangles (6, 7) fixed on the flexible material of the base (5) forming thus the gap-pivots between the elements. At the same time the bases of the triangular elements (6, 7) face each other in pairs along the bending lines while said bending lines correspond to the protrusions lines of the core folded structure. The base of the triangular elementS (6, 7) is the function of the folded core block curvature radius and the geometrical parameters of the zigzag crimp structure.The width of the gap-pivots is taken so that to provide the folding of the mandrel together with the blank forming thus the single curvature zigzag corrugated structure with the lateral direction of crimps.

Title: Snow and/or ice liquefier
Inventor: MONROE JAMES C
IPC: B07B13/00
Filed: 2004-10-20
Abstract: A method of and system for liquefying snow. The system includes a rotor-stator device (104) mounted within a melting reservoir (102) and having a slotted rotor(224) and a slotted stator (132). Snow and/or ice is deposited in a water bath in the melting reservoir. The rotor rotates at high speed, hurling particles of crystalline snow from the tips of the rotor slots onto the perpendicular faces of the stator, thereby fracturing the crystals and promoting liquefication. The high mechanical forces generated during operation of the rotor-stator device also contribute a significant amount of heat that is applied directly to the snow. The system also includes ancillary assemblies, such as heat-exchangers and snow-transport means (360). The system is operable as a stationary unit or a mobile unit.

Abstract: A flow control valve comprising a housing, in turn comprising a substance inlet opening and a substance outlet opening and a substance channel extending between the substance inlet and outlet openings. The valve further comprises:  a piston carried by the housing and movable relative thereto; a first biasing member biasing the piston towards a first piston postion in which the piston seals the substance channel; a guide channel carried by the housing; and a valve actuator movable along and whithin the guide channel between first and second actuator positions. Furthermore, the control valve comprises a second biasing member capable of biasing the piston against the bias of the first biasing member towards a second piston position in which the piston clears the substance channel, whereby the bias of the second biasing member overtakes the bias of the first biasing member on the piston when the valve actuator is in the second actuator position, without however overtaking the bias of the first biasing member when the valve actuator is in the first actuator position. When the elongated guide channel is sufficiently tilted, the valve actuator will move from the first actuator position towards the second actuator position resulting in the bias of the second biasing member overtaking the bias of the first biasing member on the piston and the piston thus being moved towards the second piston position. The movement of the piston is delayed according to the time it takes for the valve actuator to move from the first actuator position to the second actuator position.
