Abstract: High performance, metallic coated staple fibers and nonwoven insulating webs made up of such fibers are produced. The process includes providing a nonwoven substantially two-dimensional web of fibers wherein at least a portion of 50 percent of the fibers are exposed to one or the other side of the web. This web is metallized with a low emissivity metal(s) and/or alloy(s) to produce a coated web wherein at least 50 percent of the surface area of the web fibers are coated with metal and or alloy. The coated web is shredded into individual, staple fibers which are thereafter united to produce a nonwoven, lofty three-dimensional insulating web having a density of between about 0.02 to 2 pounds per cubic foot.

Filed: 1990-10-31
Abstract: The stent (1) forms a hollow cylindrical element which is made of plastic and which is plastically deformable within a range from 45 to 75 DEG  Celsius. The stent (1) is brought to the desired position, for example a stenosed area of an artery, with the aid of a heatable balloon catheter. At the position to be treated, the stent (1) is heated and is expanded in the plastic state by dilatation of the balloon (3). After cooling to the body fluid temperature, the expanded stent maintains the shape it has assumed. The implanted stent is completely degraded biologically by the vessel fluid.

Title: Apparatus for assisting the practice of the mother tongue or a foreign language,with a view to total assimilation thereof
Inventor: TOMATIS ALFRED ANGE AUGUSTE
IPC: G10L25/60
Filed: 1984-05-18
Abstract: An apparatus for assisting the practice of the mother tongue or a foreign language, with a view to total assimilation thereof, comprises a standard signal generator constituted by a mobile support of sound recordings on which are previously recorded, independently of one another, blocks of phrases or words, expressed in the language to be assimilated by a subject. A reader of these blocks of information emits the standard signals. An analysis and comparison circuit compares a standard signal and a vocal signal which corresponds to the word pronounced by the user, based on at least one parameter. When the vocal signal is not within a predetermined tolerance of the standard signal, the standard signal is repeated. If the vocal signal is within the tolerance, the next standard signal is generated. In this way, the user repeats each word until he pronounces it correctly.

Title: Assay using porosity-reduction to inhibit migration
Inventor: BARRADINE MARTIN
IPC: G01N33/558
Filed: 1999-10-01
Granted: 2000-12-06
Abstract: Device for assaying an analyte, comprising a labelling zone, where a label can bind to the analyte, in communication with a capture zone, wherein the pore size of the capture zone is such that label which is not bound to the analyte can migrate therethrough, whereas label which is bound to the analyte cannot. During migration from the labelling zone (large pore size) to the capture zone (small pore size), unbound label can pass into and through the capture zone, whereas bound label will be captured at the junction of the labelling zone and the capture zone. The device relies upon the label being smaller than the analyte, such that free label is not retarded by the capture zone. It is particularly suitable for assaying analytes such as spermatozoa, which are large in comparison with a label such as a labelled antibody.

Filed: 2000-02-02
Granted: 2003-03-12
Abstract: A blood pump 51 for assisting a heart is provided by a stator and a rotor. The rotor is rotated relative to the stator by a motor. The blood pump apparatus includes a flow rate controller 92 and a flow rate sensor 91 to avoid excessively low or reverse flow through the pump when a pulsatile flow rate is provided. The flow rate controller may include a heart caliper 400/500 for measuring the dimension of a heart ventricle to control the flow rate to avoid overly distending or contracting the ventricle. The caliper 400/500 comprises two caliper arms positioned at opposing sides of the ventricle. Measurement of the ventricle dimension may be achieved by an angular measurement device measuring changes in the angle between the arms (fig 9) or by a pair of ultrasonic transducers located at opposite sides of the ventricle (504, 505, figs 10a and 10b). The motor for the pump may comprise a magnetic drive comprising a permanent magnet (31 fig 1a) armature windings (32, fig 1a) and back-iron (33, fig 1a). The rotor may be suspended in the stator by a magnetic suspension comprising two permanent magnet arrays (11, 12 fig 1a). The rotor may be axially supported by a Lorentz-force bearing (13-18, fig 1a). The pump may also include an axial position actuator engaged with the stator or rotor to permit the axial alignment between the stator and rotor to be adjusted.
