Granted: 2006-03-07
Abstract: Systems, methods and computer program products are provided for simultaneously transmitting data over a plurality of subscriber lines, such as twisted pair telephone wires, extending between a shared device and a respective plurality of remote devices using a symbol-based discrete multi-tone transmission scheme. A destination code within a first group of frequency bands and modulated data within a second group of frequency bands different from the first group of frequency bands, are transmitted from the shared device to the remote devices. The second group of frequency bands is selected for a subscriber line connected to a remote device having the destination code within the first group of frequency bands. A number of bits transmitted within each of the frequency bands in the second group of frequency bands for a remote device is selected during a communication handshake between the remote device and the shared device by probing a subscriber line connected to the remote device to determine data rates that can be supported by the subscriber line at each of a plurality of frequency bands.

Abstract: The present invention provides a method and apparatus for forming a plurality of parts, such as spade--type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material prior to separating the continuous stock material into discrete parts, thereby enhancing the efficiency of the forming process. The present invention also provides an improved forge for forming portions of the continuous stock material into parts having a predetermined shape. The forge can be designed to provide a clearance region proximate the forward end of the ram to permit slight flexing of the forward end of the ram in a radially outward direction during forging operations. The forge can also include a lubrication system for lubricating its various components. In addition, the forge can incrementally rotate the ram after one or more parts have been forged. By repeating the incremental rotation of the ram, the forge will eventually rotate the ram a full 360°. An improved forging die is also provided which includes a back surface having a conical medial section and a pair of conical lateral sections that are recessed relative to the medial section such that forces will principally be applied to the medial section during forging operations.

Abstract: An upright carpet extractor for solution cleaning of floor and above floor surfaces has a low profile base assembly (A) including a base housing (10) and a recovery tank and nozzle assembly (18) removably mounted on the housing. The recovery tank and nozzle assembly includes a recovery tank (120, 552) for collecting recovered cleaning solution and a nozzle cover (134) which is attached to a forward portion of the recovery tank exterior to define a nozzle flowpath (138) therebetween. Working air and recovered cleaning solution are drawn through the nozzle flowpath and into the recovery tank by a motor and fan assembly (20,534) mounted to the base housing, rearward of the recovery tank. The nozzle flowpath is removed from the base together with the recovery tank when the recovery tank is to be emptied, allowing the nozzle flowpath to be rinsed conveniently to remove trapped dirt. A carrying handle (250), pivotally mounted to the recovery tank, selectively locks the recovery tank to the housing and locks a removable lid (204) of the recovery tank to the tank to seal a discharge opening (200).

Abstract: The gas to be treated, containing CO2 and a certain amount of liquid hydrocarbons greater than 14 litres per 10<6> Nm<3> of gas, is put in an absorption zone consisting of an aqueous methyldiethanolamine and an activator consisting of an aminoalkylethanolamine, to produce a treated gas with reduced CO2 content and an absorbent liquid charged with CO2. Said absorbent liquid charged with CO2 is subjected to a regeneration treatment to release the CO2 it has fixed and produce a gas fraction rich in CO2 and a regenerated adsorbent liquid, which is recycled in the absorption zone. The invention is applicable to de-acidification, in particular, of natural gases containing CO2, liquid hydrocarbons and optionally H2S.

Abstract: Provided are nucleic acid molecules which comprise at least a portion of a polymorphic genetic marker for determining whether a canine has a mutated progressive rod-cone degeneration disease (prcd) gene locus in one or both alleles. The genetic markers are located on canine chromosome 9 in a genomic region identified as the prcd-informative region. A method for making genetic markers representing polymorphic sequences located in the prcd-informative region of canine chromosome 9 comprises isolating a polymorphic DNA sequence in the prcd informative region, using oligonucleotides complementary with at least a portion of the sequence to amplify the sequence, and analyzing canine chromosome 9 in a prcd-informative region for the ability of the polymorphic sequence to co-segregate with the prcd gene locus by a linkage test. The presence of a mutated prcd gene locus in one or both alleles of a canine in a pedigree is detected by analyzing canine chromosome 9 in the canine for the presence of at least one polymorphic genetic marker, which co-segregates with the prcd gene locus, by a linkage analysis.

Abstract: Cet appareil consiste en une lampe (10) remplie de gaz et émettant des ultraviolets que l'on utilise dans un purificateur de liquides. Cette lampe (10) est alimentée par une source de haute tension en CA, mais ne possède aucune électrode métallique qui soit à l'intérieur ou en contact avec l'enceinte du gaz. Cette enceinte se compose de deux cylindres de quartz concentriques (16, 20) qui sont scellés l'un à l'autre à leurs extrémités, le gaz remplissant l'espace entre les cylindres. Un liquide de refroidissement est pompé à travers le volume (14) défini par l'intérieur du cylindre de quartz interne (16), tandis qu'un tube conducteur d'électricité (12) espacé du cylindre interne (16) assure l'apport du liquide de refroidissement et joue le rôle d'une électrode à haute tension. L'enceinte de gaz (18) est entourée d'un boîtier métallique (28) duquel elle est espacée. Ce boîtier, qui est connecté de manière à jouer le rôle de l'électrode de mise à la masse du circuit, est traversé par le fluide en écoulement que l'on traite. Le circuit électrique commence donc au tube central (12), passe par le liquide de refroidissement, l'enceinte de gaz (18) ainsi que le liquide traité à l'extérieur du cylindre de quartz externe (20), et s'étend jusqu'au boîtier (28). L'électrode à haute tension (12) est isolée électriquement de la source du liquide de refroidissement par une longueur de tuyau isolé qui assure également l'alimentation en liquide de refroidissement.

Abstract: A method and device for high speed spectroscopic constituent verification. The method includes the steps of illuminating the sample with broadband light and measuring two preselected wavelenghts of reflected light: a first nar row-range of wavelenghts a.lambda.1 that is not significantly absorbed by the constituent of interest, and a second narrow-range of wavelengths .lambda.2 that is substantially absorbed by the constituent of interest. Given the two measurements of reflection, upper and lower thresholds are determined, the latter based on a percentage of the measured baseline reflected light of wavelengths .lambda. 1.  Finally, the presence of the constituent of interest is indicated if the measure of reflected discriminant wavelength .lambda.2 is within the upper and lower threshold measures of reflected baseline light .lambda.1.  The compact device that implements the above described method includes a base unit (10) housing a near-IR discriminator circuit with a pair of selective light sensors and a light source. A  sensor unit connects to the base unit (10). The sensor unit includes a flexible neck (20) with a connecting block (24) attached at one end for mating with the base unit (10), and a hood assembly (30) attached at the other end for enclosing a light collecting and transmitting lens (32). The optics are connected by an optical fiber bundle inside the flexible neck.
