Title: A method for leakage control and localisation of leakages in the internal faces of heat exchangers
Inventor: BRUUN FAMME PER
IPC: G01M3/20
Filed: 2000-03-21
Granted: 2009-08-04
Abstract: The invention relates to a method for leakage control and localisation of leakages in the internal faces that separate the primary and secondary sides of a plate heat exchanger, wherein a leakage control is performed in a first step by a solution containing a fluorescent colorant being supplied to one of the primary and secondary sides, whereas a clear liquid that is recycled is supplied to the opposite side, whereby the presence of leakages in the heat exchanger is verified by detection of the presence of the fluorescent colorant in the clear liquid, and that, in a second step, the presence of leakages results in the other side with the solution of the fluorescent substance being pressurised for a period of time while the other side is allowed to remain filled with air, following which the heat exchanger is drained and disassembled, and the location of the leakages is determined by visual inspection of the plates.

Title: Methods for the syntheses of alfentanil, sufentanil and remifentanil
Inventor: KILLGORE J KENDALL
IPC: C07D211/58
Filed: 2000-12-04
Granted: 2009-05-26
Abstract: Synthetic pathways are disclosed for synthesizing derivatives or analogs of fentanyl. Specifically set out are pathways for synthesizing alfentanil, sufentanil and remifentanil. The disclosed methods require fewer steps and produce a greater yield of product than methods reported in the prior art. The pathways to all these compounds begin with a common pathway of condensing a piperidone with a primary amine so as to form a 4-amino-4-carboxyamino- piperidine, wherein N of said piperidone is a-N-COO- (CH2)n CH3, alkylating an N of said primary amine which was condensed with said piperidone thereby producing an N-alkyl-anilide, and hydrolyzing said -COO-(CH2)n CH3 group of said 4-amino-4-carboxyamino- piperidine following the condensation reaction so as to form a piperidine hydrolysis product. This product can then be converted to remifentanil in a 4 step reaction. Also, this hydrolysis product can be treated with a hydride to yield a 4-hydroxymethyl-piperidine which can be converted to alfentanil in 3 further steps, to sufentanil in 3 more steps, or to a variety of remifentanil analogs in tw o steps.

Patent CA-2395053-C (CA)
Inventor: AFAR DANIEL E H
IPC: C07K14/72
Filed: 2000-12-06
Granted: 2012-05-29
Abstract: Cette invention a trait à une nouvelle famille d'antigènes transmembranaires du type serpentin de surface cellulaire. Deux des protéines de cette famille sont  exclusivement ou essentiellement exprimées dans la prostate, notamment dans la prostate cancéreuse; c'est pourquoi des membres de cette famille ont été nommés "STEAP" (Six Transmembrane Epithelial Antigen of the Prostate   six antigènes transmembranaires épithéliaux de la prostate). Quatre protéines STEAP humaines particulières sont décrites et caractérisées dans cette invention. Ces protéines STEAP humaines font montre d'un degré élevé de conservation structurale entre elles mais ne témoignent pas d'une homologie structurale significative avec une quelconque protéine humaine connue. Le prototype de la famille des STEAP, la protéine STEAP-1 se présente comme étant une protéine membranaire du type IIIa, essentiellement exprimée dans des cellules prostatiques, dans des tissus humains normaux. Du point de vue structural, STEAP-1 est une protéine renfermant 339 acides aminés et caractérisée par une topologie moléculaire de six domaines transmembranaires et par la présence de N-terminus et de C-terminus intracellulaires, laissant entendre qu'elle se plie en "serpentin" en trois boucles extracellulaires et deux boucles intracellulaires. L'expression de la protéine STEAP-1 se maintient à des niveaux élevés pendant les différents stades du cancer de la prostate. La protéine STEAP-1 est, par surcroît, largement sur-exprimée dans certains autres cancers humains.

Title: Access channel structure for wireless communication system
Inventor: HOFFMANN JOHN E
IPC: H04B1/7075
Filed: 2001-02-05
Granted: 2009-06-02
Abstract: A technique for efficient implementation of pilot signals on a reverse link in a wireless communication system. An access channel is defined for the reverse link such that within each frame, or epoch, a portion is dedicated to sending only pilot symbols. Another portion of the frame is reserved for sending mostly data symbols; however, within this second portion of the frame, additional pilot symbols are interleaved among the data symbols. The pilot symbol or preamble portion of the access channel frame allows for efficient acquisition of the access signal at the base station, while providing a timing reference for determining the effects of multipath fading. In particular, a pilot correlation filter provides a phase estimate from the pilot symbols in the preamble portion, which is then used to decode the data symbols in the payload portion. An access acquisition portion of the receiver uses the phase estimates provided by the pilot correlation filter to process the output of a data symbol correlation filter. The additional pilot symbols embedded in the payload portion are used in a dot product operation to further resolve the effects of multipath fading.

Title: Rapid connection coupling
Inventor: FARWER JENS
IPC: F16L37/407
Filed: 2002-03-27
Granted: 2009-02-17
Abstract: The invention concerns a rapid connection coupling (10) for transferring high-pressure gases ad/or liquid, in particular for refilling a high-pressure, mobile container such as a gas cylinder with oxygen in a home environment or at a transfill station with a transfill device. The coupling in question comprises the following elements: a tubular housing (11), an outer sliding sleeve (18) which can slide relative to the housing (11); a number of radially expanding collet chuck elements (15) mounted on the housing (11) and provided with an engaging contour (17) which facilitates connection to a matching connection fitting (30); and a sealing piston (22) capable of sliding centrally inside the housing (11), the said sealing piston being brought into contact with the connecting fitting (30). Internal parts (e.g., pin 25b and pin 25c) of the coupling are characterized by having a reduced or minimized volume, thereby reducing the volume of fluid expelled when removing the fitting (30) from the coupling (10), thereby reducing the intensity of sound created by disconnecting the fitting (30) from the coupling (10). Additionally, the coupling (10) is characterized by being easy to use and by having a relatively low parts count.
