Title: Low profile vascular filter system
Inventor: YADAV JAY S
IPC: A61B17/00
Filed: 2003-03-11
Abstract: A removable, low profile, vascular filter system for capture and retrieval of emboli while allowing continuous perfusion of blood, comprising a guidewire having proximal and distal markers, a filter delivery and deployment system, having an outer member and an inner member, and a filter removably attached near the distal end of the inner member. The filter comprises proximal and distal basket sleeves which position the filter between the proximal and distal markers on the guidewire, after the guidewire is in position past the vessel occlusion. The guidewire placement prior to filter delivery may facilitate access to the interventional site, especially through tortuous anatomy. Also, retrievability of the filter from the wire may avoid loss of guidewire position, which may occur following removal of filters permanently attached to guidewires.

Abstract: The invention relates to a clamping tool comprising a clamping jaw (5), which is releasably fixed on a rail, preferably at the end (2) thereof, and which comprises a pin (4) that passes through an opening of the rail. The clamping jaw is releasably fixed on the rail, whereby, after pulling the pin (4) out of the opening, the clamping jaw can be fixed at an opening (3) located at another position of the rail, preferably at its other end by reinserting the pin into an opening (3) located at that position. A second clamping jaw (7) is displaceably arranged on said rail (1). A tightening element (8) is used to bring the second clamping jaw, according to the location of the first clamping jaw (5) on the rail (1), into a clamping position in the direction of the latter or in a direction away from the latter. The aim of the invention is to achieve a simplified changing from one fixing position to another fixing position on the rail. To this end, the pin (4) is assigned in a captive manner to the first clamping jaw (5) and is held i the engaged position inside the opening by the force exerted by a spring (9) that is tensioned when the bolt is pulled out of the opening (3).

Title: Remotely actuated multiple pressure direct acting relief valve
Inventor: OLSZEWSKI RICHARD A
IPC: F16K17/06
Filed: 2003-03-21
Abstract: A multiple pressure direct acting relief valve is disclosed. The multiple pressure relief valve comprises an actuating cylinder, a relief valve and an adjustment screw interconnecting the actuating cylinder and the relief valve. The relief valve includes a low pressure spring which biases a poppet valve arrangement permitting the poppet valve arrangement to be actuatable at a first pre-determined pressure. The actuating cylinder includes a piston that is biased by a high pressure spring causing an additional compressive force to be applied to the poppet valve arrangement through an actuating rod received through the adjustment screw. When pressure is applied to the piston within the actuating cylinder, an additional compressive force is applied by the high pressure spring and the actuator rod to the poppet valve arrangement causing the poppet valve arrangement to be actuatable at a second pre-determined pressure. Lock nuts are provided on the adjustment screw that interconnects the actuating cylinder and the relief valve. When the lock nuts are disengaged, the position of the adjustment screw can be moved relative to the actuating cylinder and the relief valve permitting the adjustment of both pre-determined actuating pressures for the poppet valve arrangement.

Abstract: A method of dispensing a draught beverage, for example a beer, having a water content and a dissolved gas content; the beverage issuing from a mixing nozzle 24 into a drinking glass 26. The beverage is subjected to nucleation causing nucleation sites to occur in the beverage, at which sites ice is encouraged to form. Draught beverage from a beverage supply 12 is initially cooled by chiller 16 before reaching the mixing nozzle 24 in which the beverage mixes with coolant from a coolant supply 14 before going into the glass 26. This mixing and cooling by the coolant in the mixing nozzle causes nucleation and ice to form in the beverage before it is delivered into the. glass. The coolant may be cold liquified gas, for example liquid nitrogen, or may be solid carbon dioxide.

Title: Method and device of fault location
Inventor: ROSOLOWSKI EUGENIUSZ
IPC: G01R31/08
Filed: 2001-12-14
Abstract: The present invention relates to a method for location of a fault utilizing unsynchronized measurements of three phase voltages and currents acquired at  the line terminals without synchronization. Phasors for symmetrical componen ts of the measured quantities are determined and used in the fault location algorithm. According to one embodiment, positive sequence phasors of post- fault quantities are used for estimation of the distance to fault and it is distinctive that such an estimation of a distance to fault is performed without essentially involving iterative techniques. In this embodiment, the fault location algorithm step is performed regardless of the fault type. In later steps, the type of fault may be obtained. According to another embodiment of the invention, at the occurrence of a fault, the type of fault  is determined. If it is determined that it is not a three-phase balanced fault, negative sequence phasors are used for the estimation of the distance  to fault. On the other hand, if it is a three-phase balanced fault, the incremental positive sequence phasors are used.
