Abstract: Il s'agit d'un chalumeau soudeur pour soudage à l'arc sous gaz qui comprend les éléments qui suivent. Un col; un diffuseur, à la première extrémité du col; un tube contact qui se prolonge du diffuseur; un raccord qui constitue la seconde extrémité du col et qui sert à raccorder le col au câblage d'alimentation; et un gâchette de déclenchement. Le câblage d'alimentation alimente en électricité et en gaz le chalumeau soudeur, le gaz servant à protéger les soudures de la contamination atmosphérique au fur et à mesure du soudage à l'aide du chalumeau soudeur. Le col comprend un conducteur électrique et une voie de passage pour le gaz. Le col comprend un isolant sous la forme d'un surmoulage des matières plastiques, ce surmoulage fournissant aussi au col la rigidité et la résistance aux chocs. La gâchette de déclenchement est logée par emboîtement-pression dans une douille du col.

Title: Method and system for preventing overfilling of a track system
Inventor: FIERZ WERNER
IPC: G08G1/123

Granted: 2010-10-19
Abstract: The invention relates to a decision procedure in combinational logic which requires a computing time of n for determining the congestion of a railway track system. The railway track system supports n trains, each with a route length of m itineraries. The processing steps before the request for the provision of a route can be reduced by the following steps: a) verification of whether a train can reach the next immediate track sector of a route; b) verification for a two-train variation whether a reference position of the first train prevents the second train from traveling on its route; c) new dependencies are created using transitivity and for combinations of two trains, a verification is made whether a cogent sequence exists. Step c) is iterated until no new dependencies occur or no train can reach its destination.

Abstract: A spread spectrum meter reading system enables the use of high power frequency hopping spread spectrum (HFSS) transmission at both the encoder transmitter and repeater levels of the meter reading system. A plurality of end point encoder transmitter devices (RF devices) are each connected to a utility meter and transmit high power FHSS signals containing metering data for the corresponding utility meter. A plurality of intermediate transceiver units (PET Repeaters) both receives and retransmits the high power FHSS signals. The base station (PETRC Base Unit) can receive the high power FHSS signals from both the encoder transmitter devices and the intermediate transceiver units. The intermediate transceiver units aggregates metering data from multiple encoder transmitter devices prior to block retransmission of the metering data to the base station. The high power FHSS signals are transmitted at a maximum hopping rate to reduce power consumption and increase battery life of the devices.

Abstract: A ventilation valve of a hydraulic jack is dedicated to be mounted at an outer wall of an oil storage tank of a hydraulic jack. The hydraulic jack includes a valve seat, a valve ball, and a cap. When the jack is not operated, a valve hole is opened; the vent of the cap is communicated with the oil storage tank of the jack so as to maintain the equilibrium of the pressure of the oil storage tank; thereby the piston of the pump can suck oil successfully so that the oil is absorbed into the oii chamber of the pump to be saturated therein. At the moment that the valve ball ejects upwards rapidly. the oil buffer chamber can buffer high pressure draining oil until the oil return operation of the jack is accomplished.

Title: An embolic protection device
Inventor: BRADY EAMON
IPC: A61F2/06
Filed: 1998-11-09
Granted: 2007-11-06
Abstract: An embolic protection device has a collapsible filter element (105) mounted on a carrier such as a guidewire (101). The filter element (105) collapses into the outer end of a catheter (118) for deployment and retrieval through a vascular system of a patient. The filter element (105) has a collapsible filter body with a proximal inlet end and a distal outlet end. The proximal inlet end has inlet openings sized to allow blood and embolic material enter the filter body. The outlet end has outlet openings which allow through a passage of blood but retain embolic material with the filter body. After use, the catheter (118) is movable along the guidewire (101) to engage the proximal end of the filter element and close the inlet openings before sliding over the filter element from the proximal end to the distal end to progressively collapse the filter body on the guidewire (101) for retrieval. The filter element (105) may conveniently be mounted on a tubular sleeve (104) which is slidable and rotatable on the guidewire (101) between spaced-apart stops (106, 120) on the guidewire (101) which allows some manipulation of the guidewire independently of the filter when the filter is in use.
