  • Publication number: 20040006361
    Abstract: An inner support structure for an embolic filtering device includes a tubular member having a first support region for supporting the proximal portion of a filter assembly and a second support region for supporting the distal portion of the filter assembly. The inner support structure facilitates rotation and restricts longitudinal movement of the embolic filtering device relative to a guide wire. Alternatively, the inner support structure includes a bushing coupled to the guide wire and a sleeve with a head on its proximal end positioned within a cavity in the bushing, thereby facilitating rotation and restricting longitudinal movement of the sleeve. The proximal portion of the filter assembly is supported on the sleeve. A sleeve for retaining the struts of an expandable cage of the embolic filtering device includes a central lumen for positioning the sleeve onto a guide wire and peripheral lumens for positioning and retaining the struts.

  • Patent number: 5815073
    Abstract: The system is designed to instantaneously produce the activation of the emergency lamps included in the vehicle wherein the system is applied in the event of collision, sudden braking, overturning, etc. The system may be provided fully independently from the vehicle's standard emergency lights or else may form a complement thereof to be activated as a result of any of the abovementioned situations. The activation of the system is based on the movement of a piston in the event of collision, sudden stoppage or similar situations, closing a circuit that feeds the emergency lamps via remote-controlled switches associated to lamps on either side and via an interlocking remote-controlled switch which is deactivated through a master switch that is a part of the circuit itself.

  • Patent number: 4818357
    Abstract: A vacuum chamber is provided for sputter deposition of a semiconductor homojunction. A target made of a semiconductor compound containing at least one non-metallic element is provided. A substrate for receiving the sputtered species from the target to form sequential layers of deposited semiconductor material is also provided. An electric field is provided between the target and the substrate. An inert gas is introduced sequentially at a plurality of discrete partial pressures to adjust the incident energy of the sputtered species by thermalization, for altering the mean free path of the sputtered and incident species to control the ratio of non-metallic to metallic elements in the deposited semiconductor material and create a plurality of different semiconductor material layers.

  • Patent number: 4125962
    Abstract: A gravity-operated electric switch in a figure toy. The switch has a stationary part mounted at the doll periphery, for example, in the doll's head, and a movable part slidably mounted in the stationary part and having a knob permanently projecting exteriorly of the doll. A pull exerted on the projecting end moves electrical contacts on the slidable and stationary parts together closing the switch and operating an electric device, e.g., an acoustic device, within the doll. Releasing the pull allows gravity to open the switch and merely allowing the doll sit or lie undisturbed keeps the electrical device in "off" condition. Thus if the doll is hung up by the knob the device operates, and if it is removed and laid down, operation ceases.

  • Patent number: 3994968
    Abstract: New compounds, 2-(6'-methoxynaphth-2'-yl)-propylene oxide, 2-(6'-methoxynaphth-2'-yl)proppionaldoxime, 2-hydroxy-2-(6'-methoxynaphth-2'-yl)-propionitrile, 2-(6'-methoxynaphth-2'-yl)acrylonitrile, 2-(6'-methoxynaphth-2'-yl)acrylic acid, the corresponding 5'-halo compounds and 2-(5'-halo-6'-methoxynaphth-2'-yl)propionaldehyde are useful intermediates in producing 2-(6'-methoxynaphth-2'-yl)propionic acid and the corresponding 5'-halo acids from 6-methoxy-2-acetylnaphthalene and the corresponding 5-halo compounds. The 2-propionic acids are anti-inflammatory, analgesic, anti-pyretic and anti-pruritic agents. The 2-propionaldehydes, obtained from the 2-acetyl compounds by way of the 2-propylene oxide, can be converted directly to the 2-propionic acids by way of the 2-propionaldoximes and the 2-priopionitriles or more directly by Jones oxidation.
