Abstract: A body implantable stent (16) consists of two or more generally tubular, coaxial and slidably connected stent segments (20, 22).  Each segment (20, 22) is of open weave construction, formed of multiple braided, helically wound strands of resilient material. The stent is elastically deformed to a reduced radius when deployed.  When released after positioning, the stent (16) self-expands radially and each segment (20, 22) contracts in the axial direction.  To preserve a consistent length of the stent (16) the axially outward and non-overlapping portions (30, 32) of the stent (16) can be designed for secure fixation to the tissue, for example as radially outward flares (34, 36). Alternative approaches to maintain axial length include the addition of reinforcing filaments (62) near the stent opposite ends to increase the restoring force, the provision of fixation hooks (70) at opposite ends of the stent, and securing an elongate, axially directed, flexible and inextensible wire (104) to the opposite ends of the stent.

Abstract: In a dried sludge melting furnace apparatus, at least one of following two controls is executed.  In one of the controls, the primary combustion chamber (PCC) upper combustion air supply amount and the PCC lower combustion air supply amount are adjusted so as to respectively become a target PCC upper combustion air supply amount and a target PCC lower combustion air supply amount which are obtained from an inferred PCC upper combustion air supply amount and an inferred PCC lower combustion air supply amount.  The inferred PCC upper and lower combustion air supply amounts are obtained by a fuzzy inference device (221).  In the other control, the total combustion air supply amount and the second combustion chamber (SCC) burner fuel supply amount are adjusted so as to respectively become a target combustion air supply amount and a target SCC burner fuel supply amount which are obtained from an inferred combustion air supply amount and an inferred SCC burner fuel supply amount.

Abstract: In a method of producing molten pig iron from lumpy, iron-ore-containing charging substances, the latter are reduced in a reduction shaft furnace by means of a reducing gas, wherein the iron sponge particles obtained are melted in a melter gasifier under supply of coal and oxygen-containing gas under simultaneous formation of the reducing gas, and the reducing gas is returned to the reduction zone of the shaft furnace.            To enable charging of larger amounts of fine ore and/or ore particles, such as oxidic iron fine dust incurred in a metallurgical plant, in addition to the charging substances, the fine ore and/or the ore dust is supplied with solid carbon carriers to at least one dust burner working into the melter gasifier and is reacted in a substoichiometric cumbustion reaction.

Abstract: Cette invention consiste notamment à classifier des particules selon leur composition. Les particles (12, 68, 200) sont irradiées au moyen de rayonnements électromagnétiques, habituellement des rayons X, aux deux premiers niveaux d'énergie. Les deux premières valeurs dérivées représentent l'atténuation du rayonnement de chaque particule. Une troisième valeur correspond à la différence ou au rapport entre les deux premières, et les particules sont classifiées selon que la troisième valeur indique la présence d'une substance particulière dans les particules. Dans une application, la méthode peut servir à classifier de la kimberlite diamantifère dans une fraction de particules de kimberlite contenant des inclusions de diamant et une fraction de particules de kimberlite stérile.

Title: Method and apparatus for encoding/decoding broadcast or recorded segments and monitoring audience exposure thereto
Inventor: AIJALA VICTOR A
IPC: H04H60/31
Filed: 1993-11-16
Granted: 2006-01-31
Abstract: Methods and apparatus for encoding and decoding information in broadcast or recorded segment signals are described. In certain embodiment, an audience monitoring system encodes identification information x(w) in the audio signal portion of a broadcast or recorded segment using spread spectrum encoding (100). A personal monitoring device (200) receives an acoustically reproduced version of the broadcast or recorded signal via a microphone (230), decodes the identification information from the audio signal portion despite significant ambient noise and stores (260) this information, automatically providing a diary for the audience member which is later uploaded to a centralized facility. A separate monitoring device (700) decodes additional information from the broadcast signal, which is matched with the audience diary information at the central facility. This monitor (700) may simultaneously send data to the centralized facility using a dial-up telephone line, and receive data from the centralized facility through a signal encoded using a spread spectrum technique and modulated with a broadcast signal from a third-party.

Title: Prosthesis fixturing device
Inventor: PAPPAS MICHAEL J
IPC: A61F2/46
Filed: 1995-10-10
Granted: 2003-12-30
Abstract: A tibia fixturing device comprises a metal tray formed with annularly spaced recesses in its underside at a depth of at least about 1.5 mm and from which a stem depends for axial insertion into a tibia conical cavity. The stem has a circular cylindrical portion proximal the tray and a conical portion distal the tray. Fins radially extend from the stem cylindrical portion and penetrate the tibia to provide some torsional resistance. Axially extending channels are formed about the stem periphery which channels have bottom surfaces parallel to the stem axis to provide further torsional resistance. The channels are arranged to not interlock with the cement in the axial direction to permit the cement to separate first from the device during axial removal of the device from the bone. The fins have inclined edges distal the tray and inclined radial outer edges to align and center the stem to the bone cavity edge. Cement in the tray recesses bonds the tray to a tibia resected surface to provide major torsional resistance of the tray about the cavity longitudinal axis.

The electrical conductor is connected to the n egative terminal of a power source. The other end of all the heaters are adapted to be connected to the positive terminal of the source. Accordingly, an electrically resistive heating circuit i s formed wherein the tube serves as a common for all of the heating elements. The tub ular heater can comprise an exposed end hub with a plura lity of blades extending therefrom. Each blade can have an individual heater depo sited thereon. Alternatively, every other blade can have a heater deposited thereon. The blades having no heaters function as barriers to minimize outward escape of generated vapors. These ba rrier blades also function as heat sinks for the heaters on adjacent blades.</SDOA B>

Abstract: A Brassica sp. genomic clone containing a gene promoter, which directs expression in the tapetum, was isolated. When the promoter was fused with the GUS gene and introduced into B. napus by Agrobacterium mediated transformation, this promoter controlled GUS expression in the tapetum in transgenic B. napus plants. Expression was observed from bud length 2-3 mm, which corresponds to the uninucleate microspore stage, peaked at 4-5 mm which corresponds to the binucleate microspore stage and declined to no detectable level at the open flower stage. There was no GUS expression in other tissues such as root, stem, leaf, sepal, petal or pistil. This promoter will be useful for the temporal and spatial control of gene expression in plants.
