Patent IE-921975-A1 (IE)
Title: Bidirectional valved catheter
Inventor: JR PAUL V FENTON
IPC: A61M25/00
Filed: 1992-07-01
Abstract: A valved catheter is disclosed having an elongated, flexible tubular element defining a lumen extending along an axis substantially parallel to the central axis of the tubular element, and a bidirectional check valve assembly near its distal end which controls fluid flow in the tubular element. The valve assembly includes an aspiration valve offset from the tip of the distal end and an infusion valve formed at the tip of the distal end. The aspiration valve is generally defined by port(s) in the tubular element and a sleeve within the element underlying the ports, where the sleeve normally closes the ports. The aspiration valve permits fluid flow from the bloodstream into the element when the static fluid pressure inside the distal end is lower than the static fluid pressure outside the aspiration valve by an amount sufficient to displace the sleeve to allow fluid flow through the ports. The infusion valve includes a throat formed in the distal end which tapers down to a mouth formed by jaws at the tip. The mouth is essentially closed to fluid inflow from the patient into the tubular element and normally closed to fluid outflow from the tubular element into the patient. The infusion valve permits fluid infusion into the bloodstream when the static fluid pressure inside of the tubular element sidtal end is higher than the static fluid pressure outside of the infusion valve by an amount sufficient to force the mouth open. A bidirectionally valved multiple lumen catheter is also disclosed.

Title: Device for producing light effects
IPC: A63J17/00
Filed: 1987-08-27
Abstract: A device for a loudspeaker (1) used at the same time to produce light effects has a membrane (2) and light sources (10). The opening of the membrane (2) is covered by a rotating perforated disk (5) and by a stationary perforated disk (6). The rotation of the rotating disk (5) produces the desired light effects by covering in a changeable manner the holes of both disks (5, 6). The rotation is effected by entrainment elements (11) secured to the membrane (2) and the free extremity of which lies on the rotating disk (4). The vibrations produced when the loudspeaker (1) is in operation cause said elements (11) to slide, their movement being transferred by frictional engagement to the disk (5), rotating the same.

Title: Optical communication system with two parallel transmission paths
Inventor: PERSSON ULF A
IPC: H04B10/27
Filed: 2001-02-21
Abstract: In an optical communication link a first node (30) with transmission means (50) and a second node with receiving means (40) are connected by at least two optical fibre transmission paths (100,200). One path serves as the working path, while the remaining path or paths serve as protection paths. The transmission means in the first node is connected to an optical signal power splitter (60) which couples the signal power from the transmitting means unequally into the different transmission paths. This uneven coupling of signal power imposes greater losses in one path than in the other or others. By arranging the splitter to couple a higher proportion of the transmitted optical power into the path that has the highest inherent losses the additional loss imposed on this path is reduced. Thus the maximum path loss between any two nodes can be minimised. This in turn means that the link length and also the size of the network is virtually unaffected by using the same transmitter. <IMAGE>
