Abstract: A portable marine shelter that includes a frame assembly having two lower spaced apart longitudinally extending members, or float bars, and a flexible cover that fits over the frame assembly to provide an enclosure to store a boat and the like.  A floatation system includes numerous sphere-shaped floats that are rotatably attached to the lower frame members, the floats are also free to move longitudinally along predetermined sections of the lower frame members.  The floats are substantially equally distributed between the two lower members and along each individual member.  The loosely attached floats enables the shelter to accommodate wave and wind generated motion without unduly stressing the frame assembly of the boat sheltered therein.  The entire shelter is loosely attached to a dock and loosely anchored to the bottom of the lake, etc. to provide a structure that securely protects a boat yet is capable of being moved easily to different locations.

Abstract: An efficient protocol for the synthesis of paclitaxel, paclitaxel analogs and their intermediates is described. The process includes the attachment of the paclitaxel A-ring side chain to baccatin III and for the synthesis of paclitaxel and paclitaxel analogs with variable A-ring side chain structures. A rapid and highly efficient esterification of O-protected isoserine and 3-phenylisoserine acids having N-benzyloxycarbonyl groups to the C-13 hydroxyl of 7-O-protected baccatin III is followed by a deprotection-acylation sequence to make paclitaxel, cephalomannine and various analogs, including photoaffinity labeling candidates.  The chemical process of the present invention for the production of paclitaxel, paclitaxel analogs and their intermediates may be generalized, then, as the condensation of a compound of the general formula:     (see formula I) with a taxane of the general structure:    (see formula II) to give an intermediate of the general structure:     (see formula III)

Title: Methode de mesure predictive des tensions sur une ligne telephonique
Inventor: VOGT JOHN VINCENT III
IPC: G01R31/02
Filed: 1994-07-20
Granted: 1999-01-19
Abstract: Afin de mesurer des caractéristiques (résistance, capacité et tensions étrangères) sur une ligne téléphonique, des tensions d'entrée sont couplées à la ligne par l'intermédiaire de résistances d'entrée sous trois conditions d'essai, et les paramètres sont calculés à partir de tensions de régime permanent au niveau des bornes de la ligne. Chaque tension de régime permanent est calculée par prédiction à partir de neuf échantillons de la tension à la borne au moyen d'une solution de deuxième ordre complète d'un modèle de circuit de la ligne téléphonique dérivée d'une transformation dudit modèle de circuit dans le domaine des Z à l'aide de la technique zéro-à pôle adapté. Les tensions de régime permanent peuvent ainsi être déterminées sans attendre que les tensions transitoires causées par les constantes de temps de la ligne téléphonique disparaissent, ce qui permet d'effectuer des mesures d'une rapidité considérablement accrue sur des lignes téléphoniques à constantes de temps importantes.

Title: Synthesis of speech using regenerated phase information
Inventor: GRIFFIN DANIEL W
IPC: G10L25/93
Filed: 1996-02-19
Granted: 2006-01-10
Abstract: The spectral magnitude and phase representation used in Multi-Band Excitation (MBE) based speech coding systems is improved. At the encoder the digital speech signal is divided into frames, and a fundamental frequency, voicing information, and a set of spectral magnitudes are estimated for each frame. A spectral magnitude is computed at each harmonic frequency (ie. multiples of the estimated fundamental frequency) using a new estimation method which is independent of voicing state and which corrects for any offset between the harmonic and the frequency sampling grid. The result is a fast, FFT compatible method which produces a smooth set of spectral magnitudes without the sharp discontinuities introduced by voicing transitions as found in prior MBE based speech coders. Quantization efficiency is thereby improved, producing higher speech quality at lower bit rates. In addition, smoothing methods, typically used to reduce the effect of bit errors or to enhance formants, are more effective since they are not confused by false edges (i.e.  discontinuities) at voicing transitions. Overall speech quality and intelligibility are improved. At the decoder a bit stream is received and then used to reconstruct a fundamental frequency, voicing information, and a set of spectral magnitudes for a sequence of frames. The voicing information is used to label each harmonic as either voiced or unvoiced, and for voiced harmonics an individual phase is regenerated as a function of the spectral magnitudes localized about that harmonic frequency. The decoder then synthesizes the voiced and unvoiced component and adds them to produce the synthesized speech. The regenerated phase more closely approximates actual speech in terms of peak-to-rms value relative to the prior art, thereby yielding improved dynamic range. In addition the synthesized speech is perceived as more natural and exhibits fewer phase related distortions.

Title: Dispersion de copolymeres a teneur elevee en solides a partir d'un latex et son utilisation dans des materiaux d'etancheite
Inventor: DUNAWAY JAMES H
IPC: C08F265/04
Filed: 1995-10-04
Granted: 2003-05-06
Abstract: Un procédé de polymérisation essentiellement d'un ou de plusieurs monomères d'acrylate et/ou d'acétate de vinyle en présence d'un latex a pour résultat des dispersions de particules polymères à teneurs élevées en solides, présentant des viscosités inférieures à celles traditionnellement observées. Un pourcentage pondéral important de monomères ajoutés peut être présent dans des grosses particules de formes non-sphériques. Certaines des particules de latex d'origine sont retenues pendant la polymérisation, elles augmentent la teneur en solides et abaissent la viscosité par accumulation dans les interstices entre les grosses particules. On peut faire varier facilement les teneurs en solides polymères totales de 70 à 92 % en poids ou plus, teneurs supérieures à celles obtenues par n'importe quelle polymérisation en phase aqueuse connue à ce jour. Les viscosités à des teneurs en solides très élevées deviennent pâteuses mais les matériaux restent stables en stockage ainsi que lors d'autres manipulations, sans décomposer la dispersion en une partie polymère agglomérée et une partie eau libérée. Les dispersions sont utiles pour former des agents d'étanchéité, des membranes, etc., soit avec, soit sans autres additifs. Une utilisation préférée réside dans un composé d'imperméabilisation à base d'eau d'acrylate dans lequel la teneur élevée en solides et la thixotropie de la dispersion permettent la formation d'un agent d'imperméabilisation aqueux à faible retrait.

Abstract: A metal cutting drill with replaceable cutting inserts and a length to diameter ratio of four to one or more.  Two cutting inserts are positioned in exactly opposed diametric positions, and engage the workpiece in a substantially identical manner to precisely balance -the radial forces resulting from drill axially advancing though a workpiece.  Through the use of dual cutting inserts, the drill cuts the full circumference of a bore with each one-half revolution and therefore achieves the a faster axial feed rate.  By virtue of the inserts being triangular, the curved corners on the cutting edges of the two inserts may be positioned relatively close together and yet sufficient space is left between the inserts to enable the drill shank between the inserts to be relatively thick and strong even at increased length to diameter ratios.  Through the provision of a length to diameter ratio greater than four to one, the bores which the drill is able to produce are substantially deeper at any given diameter than those achievable by prior art indexable drills.

Abstract: The invention relates to an on-load tap changer of a step switch with an energy accumulator having a lifting slide continuously movable by a drive shaft and a depressor actuating a switching shaft. According to the invention, on the switching shaft there is an axially movable insert bearing cam discs to actuate vacuum switches and mechanical switching components. Depending on the switching direction, i.e. the linear movement of the lifting slide of the energy accumulator, the switching insert is taken to an upper or lower position on the switching shaft in such a way that different cam discs become operative. It is possible with this on-load tap changer to make asymmetrical circuits in which there is the same sequence of switchgear to be moved or actuated regardless of the switching direction.
