Abstract: A catheter for ablating tissue is disclosed that has a self-centering multiray electrode assembly. The self-centering multiray electrode assembly may have a plurality of spines, each of which a preshaped, expanded configuration that curves to change an orientation of the spine from being directed towards the distal end of catheter body to being directed towards the proximal end of the catheter body. The ablation electrodes engage ostial tissue when a maximal outer diameter of the self-centering multiray electrode assembly is engaged with an inner diameter of a vessel. The compliance of each spine may vary along its length. When the self-centering multiray electrode assembly is engaged within a vessel, the ablation electrodes are brought into contact with tissue and may be used to form lesions in a circumferential path around the vessel.

Abstract: A tool (1) to insert a plurality of elongated flexible electric conductors (4) into the slots (3) of an elongated flexible insulating housing (2). The tool (1) has a passage (13) through which the housing (2) and conductors (4) move to have the conductors (4) urged into the slot (3). The passage (13) is bordered by a plurality of ramps (10) which engages the conductors (4) to urge them into the slot (3).

Abstract: A flexible electrically conductive track including an elongated flexible insulating member providing at least one longitudinally extending slot to receive an electric conductor. The conductor includes a pair of generally parallel co-extensive contact strips joined by a plurality of transverse ribs. The slots are closed by resiliently displaceable flanges which are displaced to provide access to the conductor.

Abstract: An electrical supply assembly (10) which includes an elongated base (11) which receives longitudinally extending conductors (29). The conductors (29) are formed by a plurality of “U” shaped ribs joined by longitudinally extending strips (37). An adaptor (40) is mounted on the assembly (10) and is provided with pins (22, 23 and 24) to engage the conductors (29). The adaptor (40) has a base (45) within which there are located sockets (57) to be engaged by the pins of an electric plug. The sockets (57) are attached to the pins (22, 23 and 24). The base (45) is rotatable so as to move the pins (22, 23 and 24) into contact with the conductors (29). A shutter member (47) is located within the base (45) to selectively provide access to the sockets (57).

Abstract: An opposed piston engine (10) comprising upper (12) and lower (14) cylinders and opposed pairs of pistons (16, 18) slidable therein and interconnected by rocker pivots (24, 26). A crankshaft (56) coupled to the rocker pivots (24, 26) constrains the movement of the pistons (16, 18) and is disposed with the crankshaft axis (58) intersecting the axis (44) of one of the cylinders (12, 14), whereby the geometry of the engine (10) is significantly changed thereby reducing torsional vibration and enabling a two stroke diesel version of the engine to be used as a power source for an aircraft propeller.

Abstract: An elevator door monitoring system determines if any hatch door at any floor along an elevator shaft or any other door leading to the shaft is opened while an elevator cab is away from the door. The system includes a plurality of non-contact hatch door monitors, such as infrared proximity detectors. At least one monitor is positioned on the elevator shaft at a respective location generally opposite each hatch door along the shaft. Each monitor detects the opening of the respective hatch door without direct contact therewith, e.g., by directing radiation toward the door and measuring the distance to the door. If the distance is too great, indicating that the door is open and no elevator is present, the monitor produces an alarm signal. The alarm signal is sent to a control circuit which takes the elevator out of service and operates audible and visual alarms in response thereto.
