Title: Process for making shaped copper articles
Inventor: WRIGHT ROGER N
IPC: C25D1/04
Filed: 1996-11-12
Granted: 2002-05-21
Abstract: This invention relates to a process for making shaped copper articles directly from a copper-bearing material wherein a copper bearing material (10) is contacted with an effective amount of an aqueous leaching solution (40) to form a copper-rich aqueous solution which is contacted with a water-insoluble extractant in which copper ions are transferred from the former to the latter (20, 18) forming a copper-rich extractant (51) and a copper-depleated aqueous solution (73) which are separated followed by contacting the copper-rich extractant with an aqueous stripping solution (60) transferring the copper ions from the former to the latter thereby creating a copper-rich aqueous stripping solution which is piped to an electrowinning cell (124) wherein the copper ions contained in the solution are deposited as copper powder on the cathodes (126), followed by the removal of the copper powder from the cathode (129), followed by extruding, forging, or molding the copper powder (154) to produce a shaped copper article.

Abstract: Detonator Apparatus, such as a blasting machine detonator, is provided with a miniature transformer having multi-turn primary and secondary coils. The transformer feeds a bridge wire detonator element, and has sufficient impedance to permit impedance matching with a carrier that may be as long as 7500 m. The impedance of the detonator is such that the detonator resists firing when subject to stray currents or commonly present power or communications signals. A blasting machine is provided that is specifically designed to provide a signal having a frequency in the range in which the detonator is sensitive. The blasting machine relies upon semi-conductor switching and timing circuits to control the discharge from a pair of capacitors, rather than upon an output transformer.

Abstract: L'invention concerne un procédé et un système de synchronisation d'un récepteur de signaux numériques. L'information de synchronisation est dérivée du centre de gravité de la réponse impulsionnelle du canal élevée au carré, qui est calculé directement à partir des valeurs d'échantillonnage de la courbe de fréquence du canal, ce qui rend superflu un calcul séparé de la réponse impulsionnelle du canal par l'intermédiaire d'une transformation de Fourier inverse à partir de la courbe de fréquence du canal. La courbe de réponse du canal peut être déterminée aisément par corrélation d'un signal reçu avec un signal de référence mémorisé.

Abstract: A method and apparatus for wrapping cardboard and paper rolls for protection during shipping and handling. The rolls are wrapped in a strip of wrapping material, that has a width which does not exceed the length of the roll. The roll is transferred to the wrapping station on a transporter and is stopped using a mechanical positive stop so that an edge of the cylindrical part of the roll is aligned with a first edge of the wrapper roll mounted in the wrapping station. When the roll is stopped, a first layer of the wrapper is wound on the roll. Then, if the length of the roll is greater than the width of the wrapper, the relative position of the roll and the wrapper is changed so that the second edge of the cylindrical part of the roll is aligned with the second edge of the wrapper roll, and a second layer of wrap is wound on the roll.

Abstract: A method of correcting an object-dependent spectral shift in radar interferograms has two main procedures.  In the first, the phase of the interferogram is reconstructed through phase unwrapping and subsequently smoothed for reducing noise.  In the second, the two complex-value radar images intended for forming the interferogram are suitably multiplied by a factor derived from the smoothed phase, and are subsequently low-pass-filtered.          The spectral shift dependent on the local inclination of the terrain is thus adaptively corrected and the decorrelation caused by the image geometry is extensively eliminated.  Particularly in the region of critical, mountainous terrain, the phase noise drops to a very low level.

Title: Use of dipeptidyl peptidase iv inhibitors for lowering the blood glucose level in mammals
Inventor: PAULY ROBERT P
IPC: A61K31/425
Filed: 1997-04-24
Granted: 2005-04-12
Abstract: The present invention relates to a novel method in which reduction of the activity of the enzyme Dipeptidyl Peptidase (DP IV or CD 26), or of DP IV - like enzyme activity, in the blood of mammals by specific enzyme effectors will result in a reduced degradation of the endogenous, or exogenously administrated, insulinotropic peptides (incretins), Gastric Inhibitory Polypeptide Glucose-dependent Insulinotropic Polypeptide 1-42 (GIP1-2) and Glucagon-like Peptide 1 7-36 amide (GLP-1 7-36) (or analogs of these peptides). The decrease in concentration of these peptides or their analogs, resulting from degradation by DP IV and DP IV-like enzymes, will be thus be reduced or delayed. As a consequence of the enhanced stability of the endogenous, or exogenously administered, incretins or their analogs, caused by a reduction in DP IV-activity, their insulinotropic effects are enhanced, resulting in a potentate stimulation of insulin secretion from the pancreatic islets of Langerhans, and more rapid removal of glucose from the blood. As a result, glucose tolerance is improved. As a consequence, metabolic abnormalities associated with Diabetes mellitus, including abnormalities of carbohydrate and lipid metabolism, glucosuria and severe metabolic acidosis, and chronic alterations such as microvascular and macrovascular disease and polyneuropathy, which are the consequence of prolonged, elevated circulating glucose concentrations, are prevented or alleviated. The present invention is a new approach to lowering elevated concentrations of blood glucose. It is simple, commercially useful, and is suitable to be used in the therapy, especially of human diseases, which are caused by elevated or extraordinary blood glucose levels.

Abstract: A method and a system for controlling a dynamic channel reconfiguration of an access facility in which a first bit stream is connected on a first channel to a second channel. A status associated with the first bit stream is queried. In response to the query, status information, which includes a configuration map status, is received for the first bit stream. The configuration map status for the first bit stream is then stored in a first memory area. A command is received for disconnecting the first bit stream on the first channel from the second channel, and the first channel is disconnected from the second channel. A set of parameters associated with the first channel are then groomed to match a set of parameters associated with the third channel. A command is received for connecting a second bit stream on the first channel to a third channel. A  configuration status for the second bit stream is stored in a second memory area. The first channel is then connected to the third channel, and the second bit stream on the first channel is directed to the third channel. The dynamic channel reconfiguration implementation is restored by disconnecting the first channel from the third channel, regrooming the parameters associated with the first channel, storing retrieved configuration map status for the first bit stream in the second memory area, connecting the first channel to the second channel, and directing the first bit stream on the first channel to the second channel.

Abstract: An AAL2 packet exchange device is placed in front of an ATM switch for executing CPS packet re-multiplexing into ATM cells. The AAL2 packet exchange device extracts CPS-PDUs (Common Part Sublayer- Protocol Data Units) from ATM cells which are supplied from input ATM lines, extracts CPS packets from the CPS-PDUs, alters CIDs (Channel IDentifiers) of the CPS packets if necessary so that CID collision will not occur between CPS packets supplied from different sources to be outputted to the same output ATM connection, multiplexes the CPS packets to be outputted to the same output ATM connection in ATM cells of the same output ATM connection. The CID alteration is executed by referring to a path setting table which stores each correspondence between a first internal address for discriminating between input ATM connections, an input CID, a second internal address for discriminating between output ATM connections, and an output CID.    By the CID alteration, CPS packets which have been contained in ATM cells from different sources can be multiplexed onto the same VP/VC.    Therefore, multiplexing efficiency on each ATM connection can be improved, and thereby increase in the number of ATM cells can be avoided and the load on ATM switches can be lightened.
