Title: Method of preparing a composite bone graft
Inventor: MUSCHLER GEORGE FREDERICK
IPC: A61L27/58
Filed: 1997-07-03
Abstract: The present invention provides a new and improved method for preparing a composite bone graft. The method comprises providing a bone marrow aspirate suspension and passing the bone marrow aspirate suspension through a porous, biocompatible, implantable substrate (12) to provide a composite bone graft having an enriched population of connective tissue progenitor cells. Because the method is preferably performed intraoperatively, it reduces the number of occasions the graftee must undergo invasive procedures. The invention also relates to an improved composite bone graft prepared according to the present method. The improved composite graft comprises an enriched population of connective tissue progenitor cells and a greater number of connective tissue progenitor cells per unit volume than that found in the original bone marrow aspirate. The present invention also relates to a kit comprising the apparatus (10) used for preparing the composite bone graft.

IPC: G06F11/16
Filed: 1998-07-13
Abstract: Les défaillances dans un système informatique à tolérance de pannes comprenant deux processeurs d'entrée/sortie connectés à un système de communication de données, sont détectées par la surveillance de la communication de données. Le système informatique est capable de détecter les défaillance associées à un processeur d'entrée/sortie principal ainsi qu'à des processeurs d'entrée/sortie de secours, et de distinguer les défaillances des processeurs d'entrée/sortie des défaillances de communication dans le réseau de communication de données lui-même. Outre les transmissions rythmées, divers autres types de communication de données sont utilisés pour la détection des défaillances. Le système est également capable de détecter les défaillances lorsque les processeurs d'entrée/sortie sont sur un segment de réseau commun, ce qui permet aux processeurs de surveiller le trafic de données identiques, et lorsque les processeurs sont sur différents segments où, de par le comportement de filtrage des éléments du réseau tels que les concentrateurs actifs, les processeurs sont susceptibles de ne pouvoir surveiller le trafic de données identiques.

Title: Device for outward guidance of articles transported on a conveyer
Inventor: GOLLER HANS-ULRICH
IPC: B07C5/36
Filed: 1998-09-14
Abstract: According to the invention, a stream of ar-ticles (10), e.g. drink bottles, are transported on a conveyer (12) during which certain, e.g.  de-fective, articles are guided in an outward direc-tion by means of a number of guiding segments (22), said segments moving synchronously with the conveyer over a given distance, in order to push an article (10) from the conveyer (12). The guiding segments (22) located inside a cradle (18) are adjacent to one another in the direction of transportation and can move in and out. The cradle (18) can move back and forth in the di-rection of transportation. Said cradle (18) is gen-erally controlled in such a way that it operates somewhat synchronously with the conveyer (l2) over a given distance. The length of the distance during which the cradle (18) operates somewhat synchronously with the conveyer (l2) is shorter than the distance between the first and the last guiding segment (22) inside the cradle (18) together with the minimum distance of the articles. A traveling rail (26) which is perpendicular to the direction of transportation enables said guiding segments (22) to be coupled in an individual manner according to choice.

Title: Down/up-conversion apparatus and method
Inventor: SCHIER THORSTEN
IPC: H03M1/12
Filed: 1998-09-28
Abstract: A down-converter converts an amplitude modulated high frequency signal into a low frequency or baseband signal. A first mixer (30, 32) mixes the high frequency signal into a composite signal having an in-phase component and a quadrature component. A complex bandpass filter (34) bandwith limits the composite signal into a bandwidth limited signal with an in-phase component and a quadrature component. A second mixer (36, 38) mixes the bandwidth limited signal into an intermediate signal with an in-phase component and a quadrature component, and an adder (40) adds one component of the intermediate signal to the other. A similar up-conventer performs the reverse process.

Patent CA-2316357-A1 (CA)
Inventor: VAN WECHEM GUSTAAF LOUIS
IPC: E21B19/20
Filed: 1997-12-24
Abstract: For making or breaking a coupling between a pipe section (1) and a pipe string (2) projecting from a rotary drilling rig into a bore hole in the lithosphere, the pipe section (1) is rotated relative to the pipe string (2) by applying a torque up to a make-up or breaking torque. Exertion of said torque generates a reactive torque in an opposite sense of rotation. Rotation induced by a motor (17; 50) is transferred to the pipe string (2) so that said pipe string (2) is rotated as well. The reactive torque is transferred to the pipe string (2) along a path bypassing the motor (17; 50). Thus, the make-up or breaking torque can be exerted without requiring a substantial change of the torque exerted to rotate the pipe string (2) at a constant rotational velocity in order to avoid changes of the rotational velocity of the pipe string (2). A pipe coupling device and a pipe handler for carrying out this method are described as well.

Title: Frequency selective reflector
Inventor: CHANDLER CHARLES W
IPC: H01Q19/195
Filed: 2000-08-24
Abstract: A frequency selective reflector is provided for use in an electromagnetic antenna system, wherein the frequency selective reflector reflects electromagnetic waves having two or more frequencies. The reflector includes an inner portion which has a reflective surface which will reflect at least first and second frequencies. The reflector also includes an outer portion which will reflect electromagnetic waves having the first frequency in substantially the same direction as electromagnetic waves of the first frequency reflected from the inner portion. On the other hand, the outer portion is constructed to prevent the constructive reflection of electromagnetic waves of the second frequency in the same direction as electromagnetic waves of the second frequency reflected from the inner portion. By setting the diameter between the inner and outer circuit portions to have a predetermined relationship to one another, the reflector's electrical size in terms of wavelength can be substantially equalized for the first and second frequencies so that the beam width of the radiation patterns for the first and second frequencies will be superimposed and substantially equal to one another.

Abstract: A storage container with gripping handle sidewall. The container includes a sidewall, top wall and bottom wall. The sidewall is formed with a peripheral shape which permits grasping by the user. At two spaced points the sidewall thickness is reduced to form areas of increased flexibility. The portion between the areas remains at the original strength. The user grips the container by placing the palm over the area of original strength, with the fingers and thumb, respectively, on the spaced areas of increased flexibility.      Exerting gripping pressure deforms the sidewall at the spaced areas, creating the impression of a handle in the container sidewall, and improving the reliability of the grip on the container.

Title: Identification of bacterial avirulence genes and their products; vaccines and pharmaceutical compositions containing them
Inventor: MAURELLI ANTHONY T
IPC: A61K31/455
Filed: 1999-03-31
Abstract: "Black holes" in the genomes of bacterial pathogens represent deletions of "anti-virulence" genes, i.e. genes that are detrimental to a pathogenic lifestyle. Identification of the missing genetic loci in the "black hole" identifies genes that are incompatible with the bacteria's pathogenicity. These genes, their gene products, and compounds generated by the enzymatic action of these gene products represent potential new compounds that are inhibitory to the bacterial pathogen and thus useful as pharmaceuticals. The utility of this concept is demonstrated in the missing gene for lysine decarboxylase, and the resulting inhibitory activity of cadaverine (the diaminoalkyl reaction product of lysine decarboxylase) on the Shigella enterotoxins. Diaminoalkyl compounds are therefore potent inhibitors of E. toll and Shigella spp, enterotoxins. Lysine decarboxylase generated from the gene cadA results in attenuation of the enterotoxic effects. New methods of use of diaminoalkyl compounds as medicaments are described. New uses of genetic constructs containing a cadA sequence, or other "anti-virulence" gent, for biochemical probes, for toxin receptor identification, and for pharmaceutical discovery are described. Additional uses are described for vaccines and DNA vaccine delivery.
