Title: Procede et appareil de compression de signaux dans un format de point fixe sans introduction d'une distorsion
Inventor: LEVIN JEFFREY A
IPC: H03M7/24
Filed: 1999-08-13
Abstract: L'invention concerne un procédé et un appareil de compression de signaux en point fixe sans introduire de distorsion. Les signaux sont comprimés selon une méthode d'arrondissement par vibration, les valeurs des signaux étant arrondies au chiffre supérieur et arrondies au chiffre inférieur avec une probabilité approximativement égale, ce qui annule la distorsion qui pourrait découler de l'opération d'arrondissement. On exploite les propriétés numériques du signal d'entrée afin de déterminer si la valeur du signal doit être arrondie au chiffre supérieur ou au chiffre inférieur. On peut donc introduire une compression de signaux à des points multiples dans un système sans accumuler une distorsion des signaux et dégrader les performances en aval. En outre, on peut effectuer une compression de signaux à un bit de manière particulièrement efficace avec une quantité minimale de matériel.

Title: A pipe liner, a liner product and methods for forming and installing the liner
Inventor: WOOD PETER
IPC: B29C63/34
Filed: 1999-12-01
Abstract: A method for lining, rehabilitating, repairing, and rejuvenating pipelines and passageways is disclosed. The method comprises the steps of hauling a tubular liner (10) into a section of pipeline (14) to be repaired, disposing a reforming member (34) within the liner at one end proximate one end of the pipeline, depositing a cement slug (16) in the host pipeline proximate the said one end, and expanding the liner within the pipeline against the inner surface of the said pipeline by urging the reforming member along within the liner under pressure. The outer surface of the liner is provided with a plurality of protrusions (12) in the form of grout anchor hooks which penetrate the cement along the length of the said liner thus ensuring a mechanical bond between said liner and said cement. The cement also adheres to the inner surface of the pipeline and thus a rigid, secure, water impermeable lining construction is achieved. The anchor hooks both prevent gravitational slump of the mortar, and also ensure that the liner does not fall from the cement.  A substantially uniform thickness of cement is obtained, and the lining constructions adopts a substantially identical shape to that of the host pipe after the cement has hydrated.

Filed: 2001-09-21
Abstract: A winder for winding wire onto coil supports of dynamo-electric cores with translational, rotational, and stratification motions with respect to a central longitudinal axis of the dynamo-electric core is provided. The rotational motion may preferably be provided by the rocking motion of a gear sector. The stratification motion may preferably be provided by the implementation of a spiral groove. The spiral groove preferably shares the same longitudinal axis as the winder. The rotation of the spiral groove preferably creates a relative motion between the groove and the needles, thereby producing the radial stratification motion of the needles. Additionally, the winder includes a motor arrangement which is programmable and controllable. The motor arrangement may also provide a dampening effect to limit unwanted stratification motion.

Title: Fixed address analysis of sequence tags
Inventor: FENG LI
IPC: C12Q1/6837
Filed: 2000-04-06
Abstract: Disclosed is a method for the comprehensive analysis of nucleic acid samples  and a detector composition for use in the method. The method, referred to as  Fixed Address Analysis of Sequence Tags (FAAST), involves generation of a se t of nucleic acid fragments having a variety of sticky end sequences; indexing  of the fragments into sets based on the sequence of sticky ends; associating  a detector sequence with the fragments; sequence-based capture of the indexed fragments on a detector array; and detection of the fragment labels. Generation of the multiple sticky end sequences is accomplished by incubatin g the nucleic acid sample with one or more nucleic acid cleaving reagents. The  indexed fragments are captured by hybridization and coupling, preferably by ligation, to a probe. The method allows a complex sample of nucleic acid to be quickly and easily cataloged in a reproducible and sequence-specific manner.  One form of the method allows determination of associations, in a nucleic ac id molecule, of different combinations of known or potential sequences. Another  form of the method assesses modification of sequences in nucleic acid molecules by basing cleavage of the molecules on the presence or absence of modification.

Abstract: Nestable trays are part of a pill crushing device. The trays have cylindrical midportions, spherical end portions and a planar flange. The pill crushing device has an anvil or mortar portion to engage a bottom tray, and a hammer or pestle portion to engage a top tray. The anvil portion has a recess the perimeter of which supports the bottom tray flange. A finger gap is conveniently left in the perimeter for access to the bottom tray. The hammer portion extends between two pivotable lever arms and has sufficient tolerance to allow limited independent movement of the lever arms, which in turn allows relative movement of the trays to crush pills. The hammer can contact the top tray, and may be of cylindrical form with hemispherical ends, which can itself nest in the top tray, in another version it is slightly larger and does not nest but engages the tray near the top. Another hammer version has gripping blocks, separated by a connector tube, which have concave grooves to engage the end flanges of the top tray.
