Title: Apparatus and method of removing occlusions using an ultrasonic medical device operating in a transverse mode
Inventor: RABINER ROBERT
IPC: A61B17/00
Filed: 2002-01-23
Granted: 2007-11-06
Abstract: A method for removing an occlusion includes the steps of introducing a transverse mode ultrasonic probe (22) into a blood vessel, positioning the probe (22) in proximity to the occlusion, and transmitting ultrasonic energy to the probe, until the occlusion is removed. The probe (22) has a small cross-sectional lumen and is articulable for navigating in a tortuous vessel path.  The probe (22) can be used with acoustic and/or aspirations sheaths to enhance destruction and removal of an occlusion. The probe can also be used with a balloon catheter (91).

Granted: 2009-01-27
Abstract: Cellulosic fiber composites and methods for preparing cellulosic fiber composites are provided. The cellulosic fiber composites comprise cellulosic material and a resin binder. The resin binder comprises protein hydrolysates and a synthetic resin. The synthetic resin can be phenolic resin, isocyanate resin, or combinations thereof. The protein hydrolysates provide a composite with a reduced amount of petrochemicals. The composite contains an amount of resin binder sufficient to bind the cellulosic material. The composite can also contain a silicone, silane, or combination thereof. The method employs a low moisture-content mat that does not require drying prior to pressing. Additional methods can be employed to produce finished cellulosic fiber composite articles.

Abstract: The invention consists in a capacitative electromagnetic flow meter is which excitation is performed at a frequency above the commercially available frequency and having a characteristic correction filter that corrects the gain frequency characteristic of the exciting current such that the exciting flux waveform has a flat section. In the detection unit, the value of the electrostatic capacitance between the face electrodes 4A, 4B and guard electrodes 5A, 5B is made smaller than the value of the electrostatic capacitance between the detecting face electrodes 4A, 4B and the fluid to be measured. The exciting coils are fixed to a cylindrical yoke, being electrostatically screened by coil fixing plates. Fixing by en earth ring is performed with this cylindrical yoke and the two ends or the measurement tube being symmetrical with respect to the tube axis and electrode axes. In addition, fixing is effected by filling the entire interior of the detection unit with epoxy resin.

Title: Non-fluorocarbon oil and grease barrier methods of application and packaging
Inventor: EGAN PHILIP A
IPC: D21H25/06
Filed: 2002-12-11
Granted: 2011-04-19
Abstract: A non-fluorocarbon oil and grease barrier packaging for storing materials, particularly products that need oil and grease resistant characteristics. The barrier packaging does not contain fluorocarbons, which improves the environmental rating of the oil and grease barrier packaging. The packaging is made by applying an acrylate based overprint varnish (11) to a substrate (115) and then curing the overprint varnish (11) with a curable energy source (117), which regulates a cross-link density of the overprint varnish (11).  Application can be flexography, rotogravure, or either rod or blade coated.  The overprint varnish (11) possesses oil and grease resistant characteristics, which allows packaging producers to forego use of oil and grease resistant coated substrates in their packaging manufacturing processes.

Le réseau FP en ligne comprend une pluralité de réseaux de Bragg de fibres disposés périodiquement le long d'une fibre optique. Les capteurs sont formés entre chacun des réseaux de Bragg. Une source de lumière fournit des impulsions multiplexées comme impulsions d'interrogation pour le réseau. Les impulsions de lumière sont appliquées à une extrémité du réseau de capteurs et un détecteur de lumière détecte des impulsions réfléchies. Les impulsions détectées comprennent un composite de réflexions provenant de tous les réseaux de Bragg le long de la fibre. L'appareil traite les signaux détectés en utilisant un algorithme de diffusion inverse pour détecter une réponse en phase exacte de chacun des capteurs de Bragg, tout en réduisant la diaphonie à partir d'autres capteurs de Bragg dans le réseau. Une forme de l'algorithme de diffusion inverse est un algorithme d'épluchage de couches.
